History

Brad Jorsch cd618c7a92 ustring: Handle "empty" charset like Lua does (part 2) Lua actually treats a close-bracket at the start of a bracketed character class as a literal, rather than using it to close the character class. Probably unintended behavior, but it happens. Also, have the pure-lua version throw our more informative errors on error even when falling back to string.find and the like, and fix some other weird edge cases that came up in testing.

README

This is ustring, a pure-Lua library to handle UTF-8 strings.

It implements generally the same interface as the standard string library, with
the following differences:
* Most functions work on codepoints rather than bytes or characters. Yes, this
  means that even though "á" and "á" should appear identical and represent the
  same character, the former is one codepoint (U+00E1) while the latter is two
  (U+0061 U+0301).
* Added functions isutf8, byteoffset, codepoint, gcodepoint, toNFC, toNFD.
* No workalike for string.reverse is provided.

Contents:
* README - This file.
* ustring.lua - The main file for the library.
* string.lua - Extend the string metatable with methods from this library.
* upper.lua - Data table for ustring.upper.
* lower.lua - Data table for ustring.lower.
* charsets.lua - Data tables for pattern matching functions.
* make-tables.php - Regenerate upper.lua and lower.lua using PHP's multibyte
  string library, and charsets.lua using PCRE.
* normalization-data.lua - Data tables for toNFC and toNFD.
* make-normalization-table.php - Regenerate normalization-data.lua based on the
  file includes/libs/normal/UtfNormalData.inc from MediaWiki core.
