* Update Unicode Version to 9.0.0Fumiaki MATSUSHIMA2017-01-281-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | 9.0.0 was released on June 21, 2016 http://blog.unicode.org/2016/06/announcing-unicode-standard-version-90.html http://www.unicode.org/versions/Unicode9.0.0/ There are some changes about grapheme cluster in Unicode 9.0.0: http://unicode.org/reports/tr29/#Grapheme_Cluster_Boundary_Rules ------------ I noticed that `unpack_graphemes` returns [Other] when the argument is Other ÷ Prepend (it must be [Other, Prepend]). But in [Unicode 8.0.0's Prepend has no characters](http://www.unicode.org/reports/tr29/tr29-27.html#Prepend) so we don't have to backport following patch: ```diff should_break = + if pos == eoc + true ```

| * Support extended grapheme clusters and UAX 29Adam Roben2013-11-131-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | http://www.unicode.org/reports/tr29/tr29-21.html is the version of UAX 29 that corresponds to Unicode 6.2.0. Unicode.unpack_graphemes now implements all the rules listed there, including the ones for extended grapheme clusters. I added a new optional test, test/multibyte_grapheme_break_conformance.rb, that is heavily based on test/multibyte_normalization_conformance.rb, which runs the Unicode test suite.
| * Refactor Unicode.unpack_graphemes slightlyAdam Roben2013-11-131-13/+23
| | | | | | | | This will make it easier to add the rest of the rules listed in UAX 29.

* | Freeze string literals when not mutated.schneems2015-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I wrote a utility that helps find areas where you could optimize your program using a frozen string instead of a string literal, it's called [let_it_go](https://github.com/schneems/let_it_go). After going through the output and adding `.freeze` I was able to eliminate the creation of 1,114 string objects on EVERY request to [codetriage](codetriage.com). How does this impact execution? To look at memory: ```ruby require 'get_process_mem' mem = GetProcessMem.new GC.start GC.disable 1_114.times { " " } before = mem.mb after = mem.mb GC.enable puts "Diff: #{after - before} mb" ``` Creating 1,114 string objects results in `Diff: 0.03125 mb` of RAM allocated on every request. Or 1mb every 32 requests. To look at raw speed: ```ruby require 'benchmark/ips' number_of_objects_reduced = 1_114 Benchmark.ips do |x| x.report("freeze") { number_of_objects_reduced.times { " ".freeze } } x.report("no-freeze") { number_of_objects_reduced.times { " " } } end ``` We get the results ``` Calculating ------------------------------------- freeze 1.428k i/100ms no-freeze 609.000 i/100ms ------------------------------------------------- freeze 14.363k (± 8.5%) i/s - 71.400k no-freeze 6.084k (± 8.1%) i/s - 30.450k ``` Now we can do some maths: ```ruby ips = 6_226k # iterations / 1 second call_time_before = 1.0 / ips # seconds per iteration ips = 15_254 # iterations / 1 second call_time_after = 1.0 / ips # seconds per iteration diff = call_time_before - call_time_after number_of_objects_reduced * diff * 100 # => 0.4530373333993266 miliseconds saved per request ``` So we're shaving off 1 second of execution time for every 220 requests. Is this going to be an insane speed boost to any Rails app: nope. Should we merge it: yep. p.s. If you know of a method call that doesn't modify a string input such as [String#gsub](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37) please [give me a pull request to the appropriate file](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37), or open an issue in LetItGo so we can track and freeze more strings. Keep those strings Frozen ![](https://www.dropbox.com/s/z4dj9fdsv213r4v/let-it-go.gif?dl=1)

* | Update to Unicode 7.0.0Benjamin Fleischer2014-11-151-1/+1
| | | | | | | | | | | | | | | | 7.0.0 was released on June 16, 2014 http://unicode-inc.blogspot.com.ar/2014/10/unicode-version-70-complete-text-of.html ruby bin/generate_tables
* | As of Unicode 6.3, Mongolian Vowel Separator is not whitespaceMatthew Draper2014-09-151-1/+0
| | | | | | | | | | Ruby 2.2 knows this, and no longer matches it with [[:space:]], so it's not a good candidate for testing String#squish.
* | Preload UnicodeDatabase outside the loopAkira Matsuda2014-08-181-0/+1
| | | | | | | | | | | | This fixes random multibyte_chars_test fail under Ruby 1.9.3. I don't know why the tests fail. And I really don't know why this fixes. Maybe we need some more investigation...

* | Prevent using String#scrub on RubiniusRobin Dupret2014-07-301-1/+2
| | | | | | | | | | | | Rubinius' has built-in support for String#scrub but it doesn't have yet support for ASCII-incompatible chars so for now, we should rely on the old implementation of #tidy_bytes.
* | Fix tidy_bytes for JRubyJustin Coyne2014-02-101-3/+3
| | | | | | | | | | The previous implementation was broken because JRuby (1.7.10) doesn't have a code converter for UTF-8 to UTF8-MAC.

* Use ruby's Encoding support for tidy_bytesBurke Libbey2013-05-081-39/+19
| | | | | | | | | | The previous implementation was quite slow. This leverages some of the transcoding abilities built into Ruby 1.9 instead. It is roughly 96% faster. The roundtrip through UTF_8_MAC here is because ruby won't let you transcode from UTF_8 to UTF_8. I chose the closest encoding I could find as an intermediate.

| | | | | | | | | | | This reverts commit abf8de85519141496a6773310964ec03f6106f3f. We should take a deeper look to those cases flat_map doesn't do deep flattening. irb(main):002:0> [[[1,3], [1,2]]].map{|i| i}.flatten => [1, 3, 1, 2] irb(main):003:0> [[[1,3], [1,2]]].flat_map{|i| i} => [[1, 3], [1, 2]]
