Tim Starling	ce062407ab	Fix further non-local effects of library registration ... Fixed several accidental leaks to the global namespace due to missing "local" declaration. Removed extension of the string table by mw.uri, same justification as I5d0ddb70. Change-Id: Iba1bf8e651d4ce05812e4a9a7a074cb6679297a0	2013-02-13 15:40:18 +11:00
Tim Starling	f2f866cbdd	Remove global side-effects from mw.ustring library registration ... The point of putting the unicode library in mw.ustring instead of ustring was to avoid conflicts with future upstream work, and with other libraries. It rather defeats the purpose if you then modify the global string table during module startup. Users can always set up local aliases if they feel "mw.ustring" is too much to type.

Brad Jorsch	0a8757baba	Lua ustring implementation ... This is a reimplementation of Lua's string library with support for UTF-8. The entire ustring library is implemented in pure Lua. PHP callbacks are also available for overrides: in LuaSandbox these are used for almost all functions, while in LuaStandalone they are used only for the pattern matching. Also, ustring.upper and ustring.lower are overridden using mw.language's .uc and .lc if available. It also includes a bunch of unit tests. Note that if you download the normalization tests, they may fail under LuaSandbox if you have PHP's intl extension installed and libicu on your system is too old.
