(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: - - <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" - "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> - -...and the character encoding from this code: - - <meta http-equiv="Content-type" content="text/html;charset=ENCODING"> - -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 <http://www.gnu.org/software/libiconv/> -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: <http://htmlpurifier.org/live/configdoc/plain.html> 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 <http://htmlpurifier.org/demo.php> 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: - -<?php - require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php'; - - $config = HTMLPurifier_Config::createDefault(); - $purifier = new HTMLPurifier($config); - $clean_html = $purifier->purify($dirty_html); -?> - -If your website is in a different encoding or doctype, use this code: - -<?php - require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php'; - - $config = HTMLPurifier_Config::createDefault(); - $config->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); -?> - - vim: et sw=4 sts=4 diff --git a/library/htmlpurifier-4.6.0-lite/LICENSE b/library/htmlpurifier-4.6.0-lite/LICENSE deleted file mode 100644 index 8c88a20d4..000000000 --- a/library/htmlpurifier-4.6.0-lite/LICENSE +++ /dev/null @@ -1,504 +0,0 @@ - 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. - - <one line to give the library's name and a brief idea of what it does.> - Copyright (C) <year> <name of author> - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU - Lesser General Public License for more details. - - You should have received a copy of the GNU Lesser General Public - License along with this library; if not, write to the Free Software - 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.

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 <a><span>http://foo</span></a> -- Make %URI.Munge not apply to links that have the same host as your host. -- Prevent stray </body> tag from truncating output, if a second </body> - 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 -.

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 <a> 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 <![CDATA[<body></body>]]> 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, <img src="">) - 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. -.
