Lua Library Compactor is a small terminal program, created for to easily the compaction of Lua libraries in a format nicknamed of Local Package.
In summary, Lim create a copy of the file used like argument and accomplish a serie of abbreviations and remotions of characters, trying not break the code logic. Its objective is not become the code more fast, but yes minor in relation to the characters size (and as a consequence in bytes)
Lim can be used in practically all type of program that use Lua, but its main finality is assist in the build of small libraries to the Tic80 Tiny Computer, like the libraries natives of the project TinyLibrary.
