Hi all,
LuaSrcDiet reduces the size of Lua 5.1.x source files by
aggressively removing all unnecessary whitespace and comments,
optimizing constant tokens, and renaming local variables to
shorter names.
New location: http://code.google.com/p/luasrcdiet/
Version 0.12.0 main changes:
* BUG FIX: String optimization of "\ddd" -- "00101円" was
incorrectly optimized to "101円".
* Added --opt-srcequiv: Source lexer stream equivalence checking.
* Added --opt-binequiv: Binary chunk equivalence checking.
* Single-file versions of LuaSrcDiet in various sizes.
* --opt-experimental: Experimental optimizations:
(a) Semicolon (';') operator removal
(b) Function call syntax sugar optimization.
* Some documentation files.
The important change is the addition of source lexer stream and
binary chunk equivalence testing. This provides better assurance
that a size-reduced file will still work in the same way.
The single file LuaSrcDiet.lua is 157KB in size, which reduces to
41.3KB using maximum and experimental settings.
I am planning for one more update before shifting focus to Lua
5.2.x. The update will add (a) simple local keyword removal and
(b) user directed name replacement.
Enjoy,
