About the source

30log-clean.lua

30log was initially designed for minimalistic purposes. But then commit after commit, I came up with a source code that was obviously surpassing 30 lines. As I wanted to stick to the "30-lines" rule that defines the name of this library, I had to use an ugly syntax which not much elegant, yet 100 % functional.
For those who might be interested though, the file 30log-clean.lua contains the full source code, properly formatted and well indented for your perusal.

30log-global.lua

The file 30log-global.lua features the exact same source as the original 30log.lua, excepts that it sets a global named class. This is convenient for Lua-based frameworks such as Codea.
