-PHP Markdown Extra
-==================
-
-Description
------------
-
-This is a PHP port of the original Markdown formatter written in Perl
-by John Gruber. This special "Extra" version of PHP Markdown features
-further enhancements to the syntax for making additional constructs
-such as tables and definition list.
-
-Markdown is a text-to-HTML filter; it translates an easy-to-read /
-easy-to-write structured text format into HTML. Markdown's text format
-is most similar to that of plain text email, and supports features such
-as headers, *emphasis*, code blocks, blockquotes, and links.
-
-Markdown's syntax is designed not as a generic markup language, but
-specifically to serve as a front-end to (X)HTML. You can use span-level
-HTML tags anywhere in a Markdown document, and you can use block level
-HTML tags (like and as well).
-
-For more information about Markdown's syntax, see:
-

-Please include with your report: (1) the example input; (2) the output you
-expected; (3) the output Markdown actually produced.

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
- When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
- To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
- To protect each distributor, we want to make it very clear that
-there is no warranty for the free library. Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
- Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
- When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
- We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
- For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard. To achieve this, non-free programs must be
-allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
- In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
- Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
- GNU LESSER GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
- 6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (1) uses at run time a
- copy of the library already present on the user's computer system,
- rather than copying library functions into the executable, and (2)
- will operate properly with a modified version of the library, if
- the user installs one, as long as the modified version is
- interface-compatible with the version that the work was made with.
-
- c) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- d) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- e) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded. In such case, this License incorporates the limitation as if
-written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Libraries
-
- If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change. You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
- To apply these terms, attach the following notices to the library. It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-

- Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the

-Markdownify
-===========
-* handle non-markdownifiable lists (i.e. `- asdf
`)
-* organize methods better (i.e. flushlinebreaks & setlinebreaks close to each other)
-* take a look at function names etc.
-* is the new (in rev. 93) lastclosedtag property needed?
-* word wrapping (some work is done but it's still very buggy)
-
-
-Markdownify Extra
-=================
-
-* handle table alignment with KEEP_HTML=false
-* handle tables without headings when KEEP_HTML=false is set
-* handle Markdown inside non-markdownable tags
-
-
-Implementation Thoughts
-=======================
-* non-markdownifiable lists and markdown inside non-markdownable tags as well as the current
- table implementation could be rewritten by using a rollback mechanism.
-
- example:
-
- - asdf
- asdf
-
- we come to ``, know that this might fail and create a snapshot of our current parser
- we keep on parsing and when we reach `- ` we gotta rollback and keep this
- list in HTML format.

- // - Dashes rarely occur, but they fairly unproblematic

- // - Arbitrary Unicode characters not in ASCII. Because
- // most parsers give little thought to Unicode, treatment
- // of these codepoints is basically uniform, even for
- // punctuation-like codepoints. These characters can
- // show up in non-Western pages and are supported by most
- // major browsers, for example: "MS 明朝" is a
- // legitimate font-name
- // . See
- // the CSS3 spec for more examples:
- //
- // You can see live samples of these on the Internet:
- //
- // However, most of these fonts have ASCII equivalents:
- // for example, 'MS Mincho', and it's considered
- // professional to use ASCII font names instead of
- // Unicode font names. Thanks Takeshi Terada for
- // providing this information.
- // The following characters, to my knowledge, have not been
- // used to name font names.
- // - Single quote. While theoretically you might find a
- // font name that has a single quote in its name (serving
- // as an apostrophe, e.g. Dave's Scribble), I haven't
- // been able to find any actual examples of this.
- // Internet Explorer's cssText translation (which I
- // believe is invoked by innerHTML) normalizes any
- // quoting to single quotes, and fails to escape single
- // quotes. (Note that this is not IE's behavior for all
- // CSS properties, just some sort of special casing for
- // font-family). So a single quote *cannot* be used
- // safely in the font-family context if there will be an
- // innerHTML/cssText translation. Note that Firefox 3.x
- // does this too.
- // - Double quote. In IE, these get normalized to
- // single-quotes, no matter what the encoding. (Fun
- // fact, in IE8, the 'content' CSS property gained
- // support, where they special cased to preserve encoded
- // double quotes, but still translate unadorned double
- // quotes into single quotes.) So, because their
- // fixpoint behavior is identical to single quotes, they
- // cannot be allowed either. Firefox 3.x displays
- // single-quote style behavior.
- // - Backslashes are reduced by one (so \\ -> \) every
- // iteration, so they cannot be used safely. This shows
- // up in IE7, IE8 and FF3
- // - Semicolons, commas and backticks are handled properly.
- // - The rest of the ASCII punctuation is handled properly.
- // We haven't checked what browsers do to unadorned
- // versions, but this is not important as long as the
- // browser doesn't /remove/ surrounding quotes (as IE does
- // for HTML).
- //
- // With these results in hand, we conclude that there are
- // various levels of safety:
- // - Paranoid: alphanumeric, spaces and dashes(?)
- // - International: Paranoid + non-ASCII Unicode
- // - Edgy: Everything except quotes, backslashes
- // - NoJS: Standards compliance, e.g. sod IE. Note that
- // with some judicious character escaping (since certain
- // types of escaping doesn't work) this is theoretically
- // OK as long as innerHTML/cssText is not called.
- // We believe that international is a reasonable default
- // (that we will implement now), and once we do more
- // extensive research, we may feel comfortable with dropping
- // it down to edgy.
-
- // Edgy: alphanumeric, spaces, dashes, underscores and Unicode. Use of
- // str(c)spn assumes that the string was already well formed
- // Unicode (which of course it is).
- if (strspn($font, $this->mask) !== strlen($font)) {

-
- // Historical:
- // In the absence of innerHTML/cssText, these ugly
- // transforms don't pose a security risk (as \\ and \"
- // might--these escapes are not supported by most browsers).
- // We could try to be clever and use single-quote wrapping
- // when there is a double quote present, but I have choosen

- // of escapes by one depending on what quoting style you use)

---DESCRIPTION--
-If null, class will auto-detect the doctype and, if matching XHTML 1.1 or
-XHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise,
-it will use a relaxed CDATA definition. If true, the relaxed CDATA definition
-is forced; if false, the NMTOKENS definition is forced. To get behavior
-of HTML Purifier prior to 4.0.0, set this directive to false.
-
-Some rational behind the auto-detection:
-in previous versions of HTML Purifier, it was assumed that the form of
-class was NMTOKENS, as specified by the XHTML Modularization (representing
-XHTML 1.1 and XHTML 2.0). The DTDs for HTML 4.01 and XHTML 1.0, however
-specify class as CDATA. HTML 5 effectively defines it as CDATA, but
-with the additional constraint that each name should be unique (this is not
-explicitly outlined in previous specifications).

- This directive turns on auto-paragraphing, where double newlines are
- converted in to paragraphs whenever possible. Auto-paragraphing:
-
-
- - Always applies to inline elements or text in the root node,
- - Applies to inline elements or text with double newlines in nodes
- that allow paragraph tags,
- - Applies to double newlines in paragraph tags
-
-
- p
tags must be allowed for this directive to take effect.
- We do not use br
tags for paragraphing, as that is
- semantically incorrect.
-
-
- To prevent auto-paragraphing as a content-producer, refrain from using
- double-newlines except to specify a new paragraph or in contexts where
- it has special meaning (whitespace usually has no meaning except in
- tags like pre
, so this should not be difficult.) To prevent
- the paragraphing of inline text adjacent to block elements, wrap them
- in div
tags (the behavior is slightly different outside of
- the root node.)

-AutoFormat.RemoveEmpty
-TYPE: bool
-VERSION: 3.2.0
-DEFAULT: false
---DESCRIPTION--
-
- When enabled, HTML Purifier will attempt to remove empty elements that
- contribute no semantic information to the document. The following types
- of nodes will be removed:
-
--
- Tags with no attributes and no content, and that are not empty
- elements (remove
<a></a>
but not
- <br />
), and
-
- -
- Tags with no content, except for:
- - The
colgroup
element, or
- -
- Elements with the
id
or name
attribute,
- when those attributes are permitted on those elements.
-
-
-
-
- Please be very careful when using this functionality; while it may not
- seem that empty elements contain useful information, they can alter the
- layout of a document given appropriate styling. This directive is most
- useful when you are processing machine-generated HTML, please avoid using
- it on regular user HTML.
-
-
- Elements that contain only whitespace will be treated as empty. Non-breaking
- spaces, however, do not count as whitespace. See
- %AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.
-
-
- This algorithm is not perfect; you may still notice some empty tags,
- particularly if a node had elements, but those elements were later removed
- because they were not permitted in that context, or tags that, after
- being auto-closed by another tag, where empty. This is for safety reasons
- to prevent clever code from breaking validation. The general rule of thumb:
- if a tag looked empty on the way in, it will get removed; if HTML Purifier
- made it empty, it will stay.

---DESCRIPTION--
-
-
- If you would like users to be able to define external stylesheets, but
- only allow them to specify CSS declarations for a specific node and
- prevent them from fiddling with other elements, use this directive.
- It accepts any valid CSS selector, and will prepend this to any
- CSS declaration extracted from the document. For example, if this
- directive is set to #user-content
and a user uses the
- selector a:hover
, the final selector will be
- #user-content a:hover
.
-
-
- The comma shorthand may be used; consider the above example, with
- #user-content, #user-content2
, the final selector will
- be #user-content a:hover, #user-content2 a:hover
.
-
-
- Warning: It is possible for users to bypass this measure
- using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML
- Purifier, and I am working to get it fixed. Until then, HTML Purifier
- performs a basic check to prevent this.

- Warning: It is possible for a user to mount an
- imagecrash attack using this CSS. Counter-measures are difficult;
- it is not simply enough to limit the range of CSS lengths (using
- relative lengths with many nesting levels allows for large values
- to be attained without actually specifying them in the stylesheet),
- and the flexible nature of selectors makes it difficult to selectively
- disable lengths on image tags (HTML Purifier, however, does disable
- CSS width and height in inline styling). There are probably two effective
- counter measures: an explicit width and height set to auto in all
- images in your document (unlikely) or the disabling of width and

- used is left to the reader.

-
- This is a preferred convenience directive that combines

- Specify elements and attributes that are allowed using:

- if you would like to only allow paragraphs and links, specify

- You can also use newlines instead of commas to separate elements.

-TYPE: string/null
-VERSION: 1.3.0

---DESCRIPTION--
-
-
- Munges all browsable (usually http, https and ftp)
- absolute URIs into another URI, usually a URI redirection service.
- This directive accepts a URI, formatted with a %s
where
- the url-encoded original URI should be inserted (sample:
- http://www.google.com/url?q=%s
).
-
-
- Uses for this directive:
-
-
- -
- Prevent PageRank leaks, while being fairly transparent
- to users (you may also want to add some client side JavaScript to
- override the text in the statusbar). Notice:
- Many security experts believe that this form of protection does not deter spam-bots.
-
- -
- Redirect users to a splash page telling them they are leaving your
- website. While this is poor usability practice, it is often mandated
- in corporate environments.
-
-
-
- Prior to HTML Purifier 3.1.1, this directive also enabled the munging
- of browsable external resources, which could break things if your redirection
- script was a splash page or used meta
tags. To revert to
- previous behavior, please use %URI.MungeResources.
-
-
- You may want to also use %URI.MungeSecretKey along with this directive
- in order to enforce what URIs your redirector script allows. Open
- redirector scripts can be a security risk and negatively affect the
- reputation of your domain name.
-

- Starting with HTML Purifier 3.1.1, there is also these substitutions:

- Example <a href="">
-
-
-
-
- %r
- 1 - The URI embeds a resource
(blank) - The URI is merely a link
-
-
-
- %n
- The name of the tag this URI came from
- a
-
-
- %m
- The name of the attribute this URI came from
- href
-
-
- %p
- The name of the CSS property this URI came from, or blank if irrelevant
-
-
-
-
-
- Admittedly, these letters are somewhat arbitrary; the only stipulation
- was that they couldn't be a through f. r is for resource (I would have preferred
- e, but you take what you can get), n is for name, m
- was picked because it came after n (and I couldn't use a), p is for
- property.

-VERSION: 3.1.1
-DEFAULT: false
---DESCRIPTION--
-
- If true, any URI munging directives like %URI.Munge
- will also apply to embedded resources, such as <img src="">
.
- Be careful enabling this directive if you have a redirector script
- that does not use the Location
HTTP header; all of your images
- and other embedded resources will break.
-
-
- Warning: It is strongly advised you use this in conjunction
- %URI.MungeSecretKey to mitigate the security risk of an open redirector.

-URI.MungeSecretKey
-TYPE: string/null
-VERSION: 3.1.1
-DEFAULT: NULL
---DESCRIPTION--
-
- This directive enables secure checksum generation along with %URI.Munge.
- It should be set to a secure key that is not shared with anyone else.
- The checksum can be placed in the URI using %t. Use of this checksum
- affords an additional level of protection by allowing a redirector
- to check if a URI has passed through HTML Purifier with this line:
-
-
-$checksum === hash_hmac("sha256", $url, $secret_key)
-
-
- If the output is TRUE, the redirector script should accept the URI.
-
-
-
- Please note that it would still be possible for an attacker to procure
- secure hashes en-mass by abusing your website's Preview feature or the
- like, but this service affords an additional level of protection
- that should be combined with website blacklisting.
-
-
-
- Remember this has no effect if %URI.Munge is not on.

-URI.SafeIframeRegexp
-TYPE: string/null
-VERSION: 4.4.0
-DEFAULT: NULL
---DESCRIPTION--
-
- A PCRE regular expression that will be matched against an iframe URI. This is
- a relatively inflexible scheme, but works well enough for the most common
- use-case of iframes: embedded video. This directive only has an effect if
- %HTML.SafeIframe is enabled. Here are some example values:
-
-
- %^http://www.youtube.com/embed/%
- Allow YouTube videos
- %^http://player.vimeo.com/video/%
- Allow Vimeo videos
- %^http://(www.youtube.com/embed/|player.vimeo.com/video/)%
- Allow both
-
-
- Note that this directive does not give you enough granularity to, say, disable
- all autoplay
videos. Pipe up on the HTML Purifier forums if this
- is a capability you want.

-Install
- How to install HTML Purifier
-
-HTML Purifier is designed to run out of the box, so actually using the
-library is extremely easy. (Although... if you were looking for a
-step-by-step installation GUI, you've downloaded the wrong software!)
-
-While the impatient can get going immediately with some of the sample
-code at the bottom of this library, it's well worth reading this entire
-document--most of the other documentation assumes that you are familiar
-with these contents.
-
-
----------------------------------------------------------------------------
-1. Compatibility
-
-HTML Purifier is PHP 5 only, and is actively tested from PHP 5.0.5 and
-up. It has no core dependencies with other libraries. PHP
-4 support was deprecated on December 31, 2007 with HTML Purifier 3.0.0.
-HTML Purifier is not compatible with zend.ze1_compatibility_mode.
-
-These optional extensions can enhance the capabilities of HTML Purifier:
-
- * iconv : Converts text to and from non-UTF-8 encodings
- * bcmath : Used for unit conversion and imagecrash protection
- * tidy : Used for pretty-printing HTML
-
-These optional libraries can enhance the capabilities of HTML Purifier:
-
- * CSSTidy : Clean CSS stylesheets using %Core.ExtractStyleBlocks
- * Net_IDNA2 (PEAR) : IRI support using %Core.EnableIDNA
-
----------------------------------------------------------------------------
-2. Reconnaissance
-
-A big plus of HTML Purifier is its inerrant support of standards, so
-your web-pages should be standards-compliant. (They should also use
-semantic markup, but that's another issue altogether, one HTML Purifier
-cannot fix without reading your mind.)
-
-HTML Purifier can process these doctypes:
-
-* XHTML 1.0 Transitional (default)
-* XHTML 1.0 Strict
-* HTML 4.01 Transitional
-* HTML 4.01 Strict
-* XHTML 1.1
-
-...and these character encodings:
-
-* UTF-8 (default)
-* Any encoding iconv supports (with crippled internationalization support)
-
-These defaults reflect what my choices would be if I were authoring an
-HTML document, however, what you choose depends on the nature of your
-codebase. If you don't know what doctype you are using, you can determine
-the doctype from this identifier at the top of your source code:
-
-
-
-...and the character encoding from this code:
-
-
-
-If the character encoding declaration is missing, STOP NOW, and
-read 'docs/enduser-utf8.html' (web accessible at
-http://htmlpurifier.org/docs/enduser-utf8.html). In fact, even if it is
-present, read this document anyway, as many websites specify their
-document's character encoding incorrectly.
-
-
----------------------------------------------------------------------------
-3. Including the library
-
-The procedure is quite simple:
-
- require_once '/path/to/library/HTMLPurifier.auto.php';
-
-This will setup an autoloader, so the library's files are only included
-when you use them.
-
-Only the contents in the library/ folder are necessary, so you can remove
-everything else when using HTML Purifier in a production environment.
-
-If you installed HTML Purifier via PEAR, all you need to do is:
-
- require_once 'HTMLPurifier.auto.php';
-
-Please note that the usual PEAR practice of including just the classes you
-want will not work with HTML Purifier's autoloading scheme.
-
-Advanced users, read on; other users can skip to section 4.
-
-Autoload compatibility
-----------------------
-
- HTML Purifier attempts to be as smart as possible when registering an
- autoloader, but there are some cases where you will need to change
- your own code to accomodate HTML Purifier. These are those cases:
-
- PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
- Because spl_autoload_register() doesn't exist in early versions
- of PHP 5, HTML Purifier has no way of adding itself to the autoload
- stack. Modify your __autoload function to test
- HTMLPurifier_Bootstrap::autoload($class)
-
- For example, suppose your autoload function looks like this:
-
- function __autoload($class) {
- require str_replace('_', '/', $class) . '.php';
- return true;
- }
-
- A modified version with HTML Purifier would look like this:
-
- function __autoload($class) {
- if (HTMLPurifier_Bootstrap::autoload($class)) return true;
- require str_replace('_', '/', $class) . '.php';
- return true;
- }
-
- Note that there *is* some custom behavior in our autoloader; the
- original autoloader in our example would work for 99% of the time,
- but would fail when including language files.
-
- AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED
- spl_autoload_register() has the curious behavior of disabling
- the existing __autoload() handler. Users need to explicitly
- spl_autoload_register('__autoload'). Because we use SPL when it
- is available, __autoload() will ALWAYS be disabled. If __autoload()
- is declared before HTML Purifier is loaded, this is not a problem:
- HTML Purifier will register the function for you. But if it is
- declared afterwards, it will mysteriously not work. This
- snippet of code (after your autoloader is defined) will fix it:
-
- spl_autoload_register('__autoload')
-
- Users should also be on guard if they use a version of PHP previous
- to 5.1.2 without an autoloader--HTML Purifier will define __autoload()
- for you, which can collide with an autoloader that was added by *you*
- later.
-
-
-For better performance
-----------------------
-
- Opcode caches, which greatly speed up PHP initialization for scripts
- with large amounts of code (HTML Purifier included), don't like
- autoloaders. We offer an include file that includes all of HTML Purifier's
- files in one go in an opcode cache friendly manner:
-
- // If /path/to/library isn't already in your include path, uncomment
- // the below line:
- // require '/path/to/library/HTMLPurifier.path.php';
-
- require 'HTMLPurifier.includes.php';
-
- Optional components still need to be included--you'll know if you try to
- use a feature and you get a class doesn't exists error! The autoloader
- can be used in conjunction with this approach to catch classes that are
- missing. Simply add this afterwards:
-
- require 'HTMLPurifier.autoload.php';
-
-Standalone version
-------------------
-
- HTML Purifier has a standalone distribution; you can also generate
- a standalone file from the full version by running the script
- maintenance/generate-standalone.php . The standalone version has the
- benefit of having most of its code in one file, so parsing is much
- faster and the library is easier to manage.
-
- If HTMLPurifier.standalone.php exists in the library directory, you
- can use it like this:
-
- require '/path/to/HTMLPurifier.standalone.php';
-
- This is equivalent to including HTMLPurifier.includes.php, except that
- the contents of standalone/ will be added to your path. To override this
- behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
- be found (usually, this will be one directory up, the "true" library
- directory in full distributions). Don't forget to set your path too!
-
- The autoloader can be added to the end to ensure the classes are
- loaded when necessary; otherwise you can manually include them.
- To use the autoloader, use this:
-
- require 'HTMLPurifier.autoload.php';
-
-For advanced users
-------------------
-
- HTMLPurifier.auto.php performs a number of operations that can be done
- individually. These are:
-
- HTMLPurifier.path.php
- Puts /path/to/library in the include path. For high performance,
- this should be done in php.ini.
-
- HTMLPurifier.autoload.php
- Registers our autoload handler HTMLPurifier_Bootstrap::autoload($class).
-
- You can do these operations by yourself--in fact, you must modify your own
- autoload handler if you are using a version of PHP earlier than PHP 5.1.2
- (See "Autoload compatibility" above).
-
-
----------------------------------------------------------------------------
-4. Configuration
-
-HTML Purifier is designed to run out-of-the-box, but occasionally HTML
-Purifier needs to be told what to do. If you answer no to any of these
-questions, read on; otherwise, you can skip to the next section (or, if you're
-into configuring things just for the heck of it, skip to 4.3).
-
-* Am I using UTF-8?
-* Am I using XHTML 1.0 Transitional?
-
-If you answered no to any of these questions, instantiate a configuration
-object and read on:
-
- $config = HTMLPurifier_Config::createDefault();
-
-
-4.1. Setting a different character encoding
-
-You really shouldn't use any other encoding except UTF-8, especially if you
-plan to support multilingual websites (read section three for more details).
-However, switching to UTF-8 is not always immediately feasible, so we can
-adapt.
-
-HTML Purifier uses iconv to support other character encodings, as such,
-any encoding that iconv supports
-HTML Purifier supports with this code:
-
- $config->set('Core.Encoding', /* put your encoding here */);
-
-An example usage for Latin-1 websites (the most common encoding for English
-websites):
-
- $config->set('Core.Encoding', 'ISO-8859-1');
-
-Note that HTML Purifier's support for non-Unicode encodings is crippled by the
-fact that any character not supported by that encoding will be silently
-dropped, EVEN if it is ampersand escaped. If you want to work around
-this, you are welcome to read docs/enduser-utf8.html for a fix,
-but please be cognizant of the issues the "solution" creates (for this
-reason, I do not include the solution in this document).
-
-
-4.2. Setting a different doctype
-
-For those of you using HTML 4.01 Transitional, you can disable
-XHTML output like this:
-
- $config->set('HTML.Doctype', 'HTML 4.01 Transitional');
-
-Other supported doctypes include:
-
- * HTML 4.01 Strict
- * HTML 4.01 Transitional
- * XHTML 1.0 Strict
- * XHTML 1.0 Transitional
- * XHTML 1.1
-
-
-4.3. Other settings
-
-There are more configuration directives which can be read about
-here: They're a bit boring,
-but they can help out for those of you who like to exert maximum control over
-your code. Some of the more interesting ones are configurable at the
-demo and are well worth looking into
-for your own system.
-
-For example, you can fine tune allowed elements and attributes, convert
-relative URLs to absolute ones, and even autoparagraph input text! These
-are, respectively, %HTML.Allowed, %URI.MakeAbsolute and %URI.Base, and
-%AutoFormat.AutoParagraph. The %Namespace.Directive naming convention
-translates to:
-
- $config->set('Namespace.Directive', $value);
-
-E.g.
-
- $config->set('HTML.Allowed', 'p,b,a[href],i');
- $config->set('URI.Base', 'http://www.example.com');
- $config->set('URI.MakeAbsolute', true);
- $config->set('AutoFormat.AutoParagraph', true);
-
-
----------------------------------------------------------------------------
-5. Caching
-
-HTML Purifier generates some cache files (generally one or two) to speed up
-its execution. For maximum performance, make sure that
-library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver.
-
-If you are in the library/ folder of HTML Purifier, you can set the
-appropriate permissions using:
-
- chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer
-
-If the above command doesn't work, you may need to assign write permissions
-to all. This may be necessary if your webserver runs as nobody, but is
-not recommended since it means any other user can write files in the
-directory. Use:
-
- chmod -R 0777 HTMLPurifier/DefinitionCache/Serializer
-
-You can also chmod files via your FTP client; this option
-is usually accessible by right clicking the corresponding directory and
-then selecting "chmod" or "file permissions".
-
-Starting with 2.0.1, HTML Purifier will generate friendly error messages
-that will tell you exactly what you have to chmod the directory to, if in doubt,
-follow its advice.
-
-If you are unable or unwilling to give write permissions to the cache
-directory, you can either disable the cache (and suffer a performance
-hit):
-
- $config->set('Core.DefinitionCache', null);
-
-Or move the cache directory somewhere else (no trailing slash):
-
- $config->set('Cache.SerializerPath', '/home/user/absolute/path');
-
-
----------------------------------------------------------------------------
-6. Using the code
-
-The interface is mind-numbingly simple:
-
- $purifier = new HTMLPurifier($config);
- $clean_html = $purifier->purify( $dirty_html );
-
-That's it! For more examples, check out docs/examples/ (they aren't very
-different though). Also, docs/enduser-slow.html gives advice on what to
-do if HTML Purifier is slowing down your application.
-
-
----------------------------------------------------------------------------
-7. Quick install
-
-First, make sure library/HTMLPurifier/DefinitionCache/Serializer is
-writable by the webserver (see Section 5: Caching above for details).
-If your website is in UTF-8 and XHTML Transitional, use this code:
-
-purify($dirty_html);
-?>
-
-If your website is in a different encoding or doctype, use this code:
-
-set('Core.Encoding', 'ISO-8859-1'); // replace with your encoding
- $config->set('HTML.Doctype', 'HTML 4.01 Transitional'); // replace with your doctype
- $purifier = new HTMLPurifier($config);
-
- $clean_html = $purifier->purify($dirty_html);
-?>
-

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
- When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
- To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
- To protect each distributor, we want to make it very clear that
-there is no warranty for the free library. Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
- Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
- When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
- We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
- For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard. To achieve this, non-free programs must be
-allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
- In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
- Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
- GNU LESSER GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
- 6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (1) uses at run time a
- copy of the library already present on the user's computer system,
- rather than copying library functions into the executable, and (2)
- will operate properly with a modified version of the library, if
- the user installs one, as long as the modified version is
- interface-compatible with the version that the work was made with.
-
- c) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- d) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- e) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded. In such case, this License incorporates the limitation as if
-written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,

-= KEY ====================
- # Breaks back-compat
- ! Feature
- - Bugfix
- + Sub-comment
- . Internal change
-==========================
-
-4.6.0, released 2013-11-30
-# Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
- Please update any verification scripts you may have.
-# URI parsing algorithm was made more strict, so only prefixes which
- looks like schemes will actually be schemes. Thanks
- Michael Gusev for fixing.
-# %Core.EscapeInvalidChildren is no longer supported, and no longer does
- anything.
-! New directive %Core.AllowHostnameUnderscore which allows underscores
- in hostnames.
-- Eliminate quadratic behavior in DOMLex by using a proper queue.
- Thanks Ole Laursen for noticing this.
-- Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
- behavior in the rest of the purificaiton pipeline. Thanks Chedburn
- Networks for sponsoring this work.
-- Made Linkify URL parser a bit less permissive, so that non-breaking
- spaces and commas are not included as part of URL. Thanks nAS for fixing.
-- Fix some bad interactions with %HTML.Allowed and injectors. Thanks
- David Hirtz for reporting.
-- Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
- for reporting.
-
-4.5.0, released 2013-02-17
-# Fix bug where stacked attribute transforms clobber each other;
- this also means it's no longer possible to override attribute
- transforms in later modules. No internal code was using this
- but this may break some clients.
-# We now use SHA-1 to identify cached definitions, instead of MD5.
-! Support display:inline-block
-! Support for more white-space CSS values.
-! Permit underscores in font families
-! Support for page-break-* CSS3 properties when proprietary properties
- are enabled.
-! New directive %Core.DisableExcludes; can be set to 'true' to turn off
- SGML excludes checking. If HTML Purifier is removing too much text
- and you don't care about full standards compliance, try setting this to
- 'true'.
-- Use prepend for SPL autoloading on PHP 5.3 and later.
-- Fix bug with nofollow transform when pre-existing rel exists.
-- Fix bug where background:url() always gets lower-cased
- (but not background-image:url())
-- Fix bug with non lower-case color names in HTML
-- Fix bug where data URI validation doesn't remove temporary files.
- Thanks Javier Marín Ros for reporting.
-- Don't remove certain empty tags on RemoveEmpty.
-
-4.4.0, released 2012-01-18
-# Removed PEARSax3 handler.
-# URI.Munge now munges URIs inside the same host that go from https
- to http. Reported by Neike Taika-Tessaro.
-# Core.EscapeNonASCIICharacters now always transforms entities to
- entities, even if target encoding is UTF-8.
-# Tighten up selector validation in ExtractStyleBlocks.
- Non-syntactically valid selectors are now rejected, along with
- some of the more obscure ones such as attribute selectors, the
- :lang pseudoselector, and anything not in CSS2.1. Furthermore,
- ID and class selectors now work properly with the relevant
- configuration attributes. Also, mute errors when parsing CSS
- with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
-! Added support for 'scope' attribute on tables.
-! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
-! Properly handle sub-lists directly nested inside of lists in
- a standards compliant way, by moving them into the preceding -
-! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
- limited allowed comments in untrusted situations.
-! Implement iframes, and allow them to be used in untrusted mode with
- %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
-
for submitting an initial version of the patch.
-! The Forms module now works properly for transitional doctypes.
-! Added support for internationalized domain names. You need the PEAR
- Net_IDNA2 module to be in your path; if it is installed, ensure the
- class can be loaded and then set %Core.EnableIDNA to true.
-- Color keywords are now case insensitive. Thanks Yzmir Ramirez
- for reporting.
-- Explicitly initialize anonModule variable to null.
-- Do not duplicate nofollow if already present. Thanks 178
- for reporting.
-- Do not add nofollow if hostname matches our current host. Thanks 178
- for reporting, and Neike Taika-Tessaro for helping diagnose.
-- Do not unset parser variable; this fixes intermittent serialization
- problems. Thanks Neike Taika-Tessaro for reporting, bill
- <10010tiger@gmail.com> for diagnosing.
-- Fix iconv truncation bug, where non-UTF-8 target encodings see
- output truncated after around 8000 characters. Thanks Jörg Ludwig
- for reporting.
-- Fix broken table content model for XHTML1.1 (and also earlier
- versions, although the W3C validator doesn't catch those violations).
- Thanks GlitchMr for reporting.
-
-4.3.0, released 2011-03-27
-# Fixed broken caching of customized raw definitions, but requires an
- API change. The old API still works but will emit a warning,
- see http://htmlpurifier.org/docs/enduser-customize.html#optimized
- for how to upgrade your code.
-# Protect against Internet Explorer innerHTML behavior by specially
- treating attributes with backticks but no angled brackets, quotes or
- spaces. This constitutes a slight semantic change, which can be
- reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
- and Mario Heiderich.
-# Protect against cssText/innerHTML by restricting allowed characters
- used in fonts further than mandated by the specification and encoding
- some extra special characters in URLs. Reported by Neike
- Taika-Tessaro and Mario Heiderich.
-! Added %HTML.Nofollow to add rel="nofollow" to external links.
-! More types of SPL autoloaders allowed on later versions of PHP.
-! Implementations for position, top, left, right, bottom, z-index
- when %CSS.Trusted is on.
-! Add %Cache.SerializerPermissions option for custom serializer
- directory/file permissions
-! Fix longstanding bug in Flash support for non-IE browsers, and
- allow more wmode attributes.
-! Add %CSS.AllowedFonts to restrict permissible font names.
-- Switch to an iterative traversal of the DOM, which prevents us
- from running out of stack space for deeply nested documents.
- Thanks Maxim Krizhanovsky for contributing a patch.
-- Make removal of conditional IE comments ungreedy; thanks Bernd
- for reporting.
-- Escape CDATA before removing Internet Explorer comments.
-- Fix removal of id attributes under certain conditions by ensuring
- armor attributes are preserved when recreating tags.
-- Check if schema.ser was corrupted.
-- Check if zend.ze1_compatibility_mode is on, and error out if it is.
- This safety check is only done for HTMLPurifier.auto.php; if you
- are using standalone or the specialized includes files, you're
- expected to know what you're doing.
-- Stop repeatedly writing the cache file after I'm done customizing a
- raw definition. Reported by ajh.
-- Switch to using require_once in the Bootstrap to work around bad
- interaction with Zend Debugger and APC. Reported by Antonio Parraga.
-- Fix URI handling when hostname is missing but scheme is present.
- Reported by Neike Taika-Tessaro.
-- Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
- for reporting.
-- Fix harmless notice from indexing into empty string. Thanks Matthijs
- Kooijman for reporting.
-- Don't autoclose no parent elements are able to support the element
- that triggered the autoclose. In particular fixes strange behavior
- of stray - tags. Thanks pkuliga@gmail.com for reporting and
- Neike Taika-Tessaro
for debugging assistance.
-
-4.2.0, released 2010-09-15
-! Added %Core.RemoveProcessingInstructions, which lets you remove
- ... ?> statements.
-! Added %URI.DisableResources functionality; the directive originally
- did nothing. Thanks David Rothstein for reporting.
-! Add documentation about configuration directive types.
-! Add %CSS.ForbiddenProperties configuration directive.
-! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
- to utilize full-screen mode.
-! Add optional support for the file
URI scheme, enable
- by explicitly setting %URI.AllowedSchemes.
-! Add %Core.NormalizeNewlines options to allow turning off newline
- normalization.
-- Fix improper handling of Internet Explorer conditional comments
- by parser. Thanks zmonteca for reporting.
-- Fix missing attributes bug when running on Mac Snow Leopard and APC.
- Thanks sidepodcast for the fix.
-- Warn if an element is allowed, but an attribute it requires is
- not allowed.
-
-4.1.1, released 2010-05-31
-- Fix undefined index warnings in maintenance scripts.
-- Fix bug in DirectLex for parsing elements with a single attribute
- with entities.
-- Rewrite CSS output logic for font-family and url(). Thanks Mario
- Heiderich for reporting and Takeshi
- Terada for suggesting the fix.
-- Emit an error for CollectErrors if a body is extracted
-- Fix bug where in background-position for center keyword handling.
-- Fix infinite loop when a wrapper element is inserted in a context
- where it's not allowed. Thanks Lars for reporting.
-- Remove +x bit and shebang from index.php; only supported mode is to
- explicitly call it with php.
-- Make test script less chatty when log_errors is on.
-
-4.1.0, released 2010-04-26
-! Support proprietary height attribute on table element
-! Support YouTube slideshows that contain /cp/ in their URL.
-! Support for data: URI scheme; not enabled by default, add it using
- %URI.AllowedSchemes
-! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
-! Support for Internet Explorer compatibility with %HTML.SafeObject
- using %Output.FlashCompat.
-! Handle properly, by inserting the necessary - tag.
-- Always quote the insides of url(...) in CSS.
-
-4.0.0, released 2009-07-07
-# APIs for ConfigSchema subsystem have substantially changed. See
- docs/dev-config-bcbreaks.txt for details; in essence, anything that
- had both namespace and directive now have a single unified key.
-# Some configuration directives were renamed, specifically:
- %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
- %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
- %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
- %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
- As usual, the old directive names will still work, but will throw E_NOTICE
- errors.
-# The allowed values for class have been relaxed to allow all of CDATA for
- doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
- %Attr.ClassUseCDATA to false.
-# Instead of appending the content model to an old content model, a blank
- element will replace the old content model. You can use #SUPER to get
- the old content model.
-! More robust support for name="" and id=""
-! HTMLPurifier_Config::inherit($config) allows you to inherit one
- configuration, and have changes to that configuration be propagated
- to all of its children.
-! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
- the name attribute when set. Use with care. Thanks Ian Cook for
- sponsoring.
-! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
- tags that contain non-breaking spaces as well other whitespace. You
- can also modify which tags should have maintained with
- %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
-! Implement %Attr.AllowedClasses, which allows administrators to restrict
- classes users can use to a specified finite set of classes, and
- %Attr.ForbiddenClasses, which is the logical inverse.
-! You can now maintain your own configuration schema directories by
- creating a config-schema.php file or passing an extra argument. Check
- docs/dev-config-schema.html for more details.
-! Added HTMLPurifier_Config->serialize() method, which lets you save away
- your configuration in a compact serial file, which you can unserialize
- and use directly without having to go through the overhead of setup.
-- Fix bug where URIDefinition would not get cleared if it's directives got
- changed.
-- Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
-- Fix bug in Linkify autoformatter involving http://foo
-- Make %URI.Munge not apply to links that have the same host as your host.
-- Prevent stray tag from truncating output, if a second
- is present.
-. Created script maintenance/rename-config.php for renaming a configuration
- directive while maintaining its alias. This script does not change source code.
-. Implement namespace locking for definition construction, to prevent
- bugs where a directive is used for definition construction but is not
- used to construct the cache hash.
-
-3.3.0, released 2009-02-16
-! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
-! Implement generic property list classess
-- Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
- does not do the "right thing" with characters not supported in the output
- set.
-- Spellcheck UTF-8: The Secret To Character Encoding
-- Fix improper removal of the contents of elements with only whitespace. Thanks
- Eric Wald for reporting.
-- Fix broken test suite in versions of PHP without spl_autoload_register()
-- Fix degenerate case with YouTube filter involving double hyphens.
- Thanks Pierre Attar for reporting.
-- Fix YouTube rendering problem on certain versions of Firefox.
-- Fix CSSDefinition Printer problems with decorators
-- Add text parameter to unit tests, forces text output
-. Add verbose mode to command line test runner, use (--verbose)
-. Turn on unit tests for UnitConverter
-. Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
-. Fix newline errors that caused spurious failures when CRLF HTML Purifier was
- tested on Linux.
-. Removed trailing whitespace from all text files, see
- remote-trailing-whitespace.php maintenance script.
-. Convert configuration to use property list backend.
-
-3.2.0, released 2008-10-31
-# Using %Core.CollectErrors forces line number/column tracking on, whereas
- previously you could theoretically turn it off.
-# HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
- use handleEnd() instead.
-! %Output.AttrSort for when you need your attributes in alphabetical order to
- deal with a bug in FCKEditor. Requested by frank farmer.
-! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
-! Proper support for name attribute. It is now allowed and equivalent to the id
- attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
- is heavy (for all doctypes).
-! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
- use on hand-written HTML.
-! Add error-cases for unsupported elements in MakeWellFormed. This enables
- the strategy to be used, standalone, on untrusted input.
-! %Core.AggressivelyFixLt is on by default. This causes more sensible
- processing of left angled brackets in smileys and other whatnot.
-! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
- 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
- the --only-phpt parameter, although for backwards-compatibility the flag
- will still work.
-! AutoParagraph auto-formatter will now preserve double-newlines upon output.
- Users who are not performing inbound filtering, this may seem a little
- useless, but as a bonus, the test suite and handling of edge cases is also
- improved.
-! Experimental implementation of forms for %HTML.Trusted
-! Track column numbers when maintain line numbers is on
-! Proprietary 'background' attribute on table-related elements converted into
- corresponding CSS. Thanks Fusemail for sponsoring this feature!
-! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
- supertype.
-! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
- time of operation varies slightly from notifyEnd() as *all* end tokens are
- processed by the injector before they are subject to the well-formedness rules.
-! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
- basename of image when not present.
-! %AutoFormat.DisplayLinkURI neuters tags into plain text URLs.
-- Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
- the other involving an undefined $is_folder error.
-- Throw error when %Core.Encoding is set to a spurious value. Previously,
- this errored silently and returned false.
-- Redirected stderr to stdout for flush error output.
-- %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
- available.
-- Do not re-munge URL if the output URL has the same host as the input URL.
- Requested by Chris.
-- Fix error in documentation regarding %Filter.ExtractStyleBlocks
-- Prevent ]]> from triggering %Core.ConvertDocumentToFragment
-- Fix bug with inline elements in blockquotes conflicting with strict doctype
-- Detect if HTML support is disabled for DOM by checking for loadHTML() method.
-- Fix bug where dots and double-dots in absolute URLs without hostname were
- not collapsed by URIFilter_MakeAbsolute.
-- Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
- by reordering their addition.
-- Will now throw exception on many error conditions during lexer creation; also
- throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
- is being used.
-- Detect if domxml extension is loaded, and use DirectLEx accordingly.
-- Improve handling of big numbers with floating point arithmetic in UnitConverter.
- Reported by David Morton.
-. Strategy_MakeWellFormed now operates in-place, saving memory and allowing
- for more interesting filter-backtracking
-. New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
- index to reprocess tokens.
-. StringHashParser now allows for multiline sections with "empty" content;
- previously the section would remain undefined.
-. Added --quick option to multitest.php, which tests only the most recent
- release for each series.
-. Added --distro option to multitest.php, which accepts either 'normal' or
- 'standalone'. This supercedes --exclude-normal and --exclude-standalone
-
-3.1.1, released 2008-06-19
-# %URI.Munge now, by default, does not munge resources (for example,
)
- In order to enable this again, please set %URI.MungeResources to true.
-! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
- and height/width HTML with %HTML.MaxImgLength.
-! %URI.MungeSecretKey for secure URI munging. Thanks Chris
- for sponsoring this feature. Check out the corresponding documentation
- for details. (Att Nightly testers: The API for this feature changed before
- the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
- %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
-! Implemented post URI filtering. Set member variable $post to true to set
- a URIFilter as such.
-! Allow modules to define injectors via $info_injector. Injectors are
- automatically disabled if injector's needed elements are not found.
-! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
- Thanks Chris for sponsoring. If you've been using ad hoc code from the
- forums, PLEASE use this instead.
-! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
- embedded, tag name, attribute name, CSS property name). See %URI.Munge
- for more details. Requested by Jochem Blok.
-- Disable percent height/width attributes for img.
-- AttrValidator operations are now atomic; updates to attributes are not
- manifest in token until end of operations. This prevents naughty internal
- code from directly modifying CurrentToken when they're not supposed to.
- This semantics change was requested by frank farmer.
-- Percent encoding checks enabled for URI query and fragment
-- Fix stray backslashes in font-family; CSS Unicode character escapes are
- now properly resolved (although *only* in font-family). Thanks Takeshi Terada
- for reporting.
-- Improve parseCDATA algorithm to take into account newline normalization
-- Account for browser confusion between Yen character and backslash in
- Shift_JIS encoding. This fix generalizes to any other encoding which is not
- a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
-- Fix missing configuration parameter in Generator calls. Thanks vs for the
- partial patch.
-- Improved adherence to Unicode by checking for non-character codepoints.
- Thanks Geoffrey Sneddon for reporting. This may result in degraded
- performance for extremely large inputs.
-- Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
- for reporting.
-. Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
- handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
- this class.
-. API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
- to __construct($min, $max). __construct(true) is equivalent to
- __construct('0').
-. Added HTMLPurifier_AttrDef_Switch class
-. Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
- up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
- get this called with the configuration object. All modules now
- use this rather than __construct(), although legacy code using constructors
- will still work--the new format, however, lets modules access the
- configuration object for HTML namespace dependant tweaks.
-. AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
-. ConfigSchema data-structure heavily optimized; on average it uses a third
- the memory it did previously. The interface has changed accordingly,
- consult changes to HTMLPurifier_Config for details.
-. Variable parsing types now are magic integers instead of strings
-. Added benchmark for ConfigSchema
-. HTMLPurifier_Generator requires $config and $context parameters. If you
- don't know what they should be, use HTMLPurifier_Config::createDefault()
- and new HTMLPurifier_Context().
-. Printers now properly distinguish between output configuration, and
- target configuration. This is not applicable to scripts using
- the Printers for HTML Purifier related tasks.
-. HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
- fatal errors will ensue.
-. URIFilter->prepare can return false in order to abort loading of the filter
-. Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
- an external resource.
-. %URI.Munge functionality factored out into a post-filter class.
-. Added CurrentCSSProperty context variable during CSS validation
-
-3.1.0, released 2008-05-18
-# Unnecessary references to objects (vestiges of PHP4) removed from method
- signatures. The following methods do not need references when assigning from
- them and will result in E_STRICT errors if you try:
- + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
- + HTMLPurifier_ConfigSchema::instance()
- + HTMLPurifier_DefinitionCacheFactory::instance()
- + HTMLPurifier_DefinitionCacheFactory->create()
- + HTMLPurifier_DoctypeRegistry->register()
- + HTMLPurifier_DoctypeRegistry->get()
- + HTMLPurifier_HTMLModule->addElement()
- + HTMLPurifier_HTMLModule->addBlankElement()
- + HTMLPurifier_LanguageFactory::instance()
-# Printer_ConfigForm's get*() functions were static-ified
-# %HTML.ForbiddenAttributes requires attribute declarations to be in the
- form of tag@attr, NOT tag.attr (which will throw an error and won't do
- anything). This is for forwards compatibility with XML; you'd do best
- to migrate an %HTML.AllowedAttributes directives to this syntax too.
-! Allow index to be false for config from form creation
-! Added HTMLPurifier::VERSION constant
-! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
- and allows for version numbers like "3.1.0-dev".
-! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
-! HTML Purifier's URI handling is a lot more robust, with much stricter
- validation checks and better percent encoding handling. Thanks Gareth Heyes
- for indicating security vulnerabilities from lax percent encoding.
-! Bootstrap autoloader deals more robustly with classes that don't exist,
- preventing class_exists($class, true) from barfing.
-- InterchangeBuilder now alphabetizes its lists
-- Validation error in configdoc output fixed
-- Iconv and other encoding errors muted even with custom error handlers that
- do not honor error_reporting
-- Add protection against imagecrash attack with CSS height/width
-- HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
-- Fixed and revamped broken ConfigForm smoketest
-- Bug with bool/null fields in Printer_ConfigForm fixed
-- Bug with global forbidden attributes fixed
-- Improved error messages for allowed and forbidden HTML elements and attributes
-- Missing (or null) in configdoc documentation restored
-- If DOM throws and exception during parsing with PH5P (occurs in newer versions
- of DOM), HTML Purifier punts to DirectLex
-- Fatal error with unserialization of ScriptRequired
-- Created directories are now chmod'ed properly
-- Fixed bug with fallback languages in LanguageFactory
-- Standalone testing setup properly with autoload
-. Out-of-date documentation revised
-. UTF-8 encoding check optimization as suggested by Diego
-. HTMLPurifier_Error removed in favor of exceptions
-. More copy() function removed; should use clone instead
-. More extensive unit tests for HTMLDefinition
-. assertPurification moved to central harness
-. HTMLPurifier_Generator accepts $config and $context parameters during
- instantiation, not runtime
-. Double-quotes outside of attribute values are now unescaped
-
-3.1.0rc1, released 2008-04-22
-# Autoload support added. Internal require_once's removed in favor of an
- explicit require list or autoloading. To use HTML Purifier,
- you must now either use HTMLPurifier.auto.php
- or HTMLPurifier.includes.php; setting the include path and including
- HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
- as well to register our autoload handler (or modify your autoload function
- to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
- HTMLPurifier.safe-includes.php for a less performance friendly but more
- user-friendly library load.
-# HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
