(Two + extra characters were duplicated before the ending brackets.) + +* Faster function call syntax sugar optimization using a one-pass + token deletion loop. + +WHAT'S NEW IN VERSION 0.12.0 +---------------------------- + +* Added single-file versions of LuaSrcDiet in various sizes. First + done by some other projects that packaged LuaSrcDiet, e.g. eLua. + +* BUG FIX: String optimization of "\ddd" type escape mechanism, + "\00101" was incorrectly optimized to "\101". + +* --opt-srcequiv: Source equivalence checking. Tries hard to compare + 'before' and 'after' lexer token streams for equivalence. + +* --opt-binequiv: Binary chunk equivalence checking. Tries hard to + compare 'before' and 'after' binary chunks for equivalence. + +* When using --opt-eols, the last EOL character is now removed. + +* --opt-experimental: Turns on a few experimental optimizations: + (a) ';' operator removal (deleted or turned into whitespace). + (b) f("string") f('string') f([[string]]) calls are turned + into their syntactic sugar equivalents, e.g. f"string" + +* Plugins are now embedded into single-file versions. + +* First release of completed documentation files. + +* New Makefile and numerous minor updates. + +* Old code for Lua 5.0 removed. + +BUGS +---- + +* Nothing in my list. See below for limitations... + +INCOMPLETE SUPPORT +------------------ + +* Locals optimization does NOT understand implicit 'arg' locals in + vararg functions (see option LUA_COMPAT_VARARG in the Lua sources). + +* NO support in lexer for decimal points other than '.'. + +* NO support in lexer for Lua 5.0.x nested long strings. + +EXPERIMENTAL SOFTWARE +--------------------- + +LuaSrcDiet is "experimental software". For LuaSrcDiet, this means that +it was coded for one user -- the coder. Although I may be able to help +LuaSrcDiet users, there should not be any expectation of 'support'. + +Don't hook this thing up to nuclear missiles. + +I don't have the time for steady maintenance or for building up and +cultivating a user base, so developers are welcome to fork LuaSrcDiet or +incorporate it into their own software, as long as authorship +attribution for LuaSrcDiet source code is maintained. Say if LuaSrcDiet +is called as a separate program, then it is simply an aggregation of +separate software and each program should stick to its own license. + +Programs you process using LuaSrcDiet are of course not affected at all +by LuaSrcDiet's license; it's just a text filter. See COPYRIGHT. If you +insist on extreme COPYRIGHT views, then better delete this whole thing +right away, then gouge your eyes out. :-p + +OLDER STUFF +----------- + +There has been some slash-and-burn going on. I'm inclined to move +forward, and not spend time maintaining older stuff forever. If you +still need the older stuff, they can be found in: + +* Lua 5.0.x old versions: last seen in version 0.11.2. + +* Lua 5.1.x old codebase: last seen in version 0.11.2. + +FUTURE PLANS +------------ + +Lua 5.1.x releases for LuaSrcDiet will pretty much stagnate at 0.12.1 +after implementation of a couple more experimental optimizations, and +effort will be shifted towards something for Lua 5.2.x. The timeline for +this is indeterminate. + +======================================================================== + +USING LUASRCDIET + +Now is a good time to take a look at the documentation. Start with +LuaSrcDiet.html in the doc directory. + +LuaSrcDiet is now packaged as a single-file Lua script for maximum +convenience. Just drop it in and splice something into your Makefile. + +New source stream and binary chunk equivalence checking minimizes the +possibility of LuaSrcDiet borking your stuff. + +======================================================================== + +ACKNOWLEDGEMENTS + +Coded using SciTE. Developed mostly under Cygwin with a generic Lua +5.1.4 binary. + +======================================================================== + +FEEDBACK + +Feedback and contributions are welcome.

If your material is +self-contained, you can retain a copyright notice for those material in +your own name, as long as you use the same Lua 5/MIT-style copyright. + +Enjoy! + +Kein-Hong Man (esq.) +Kuala Lumpur +Malaysia 20120407 |
