Lum is a custom programming language made by me that compiles to lua.
It has two parts to it, a lua library, lum.lua, and a compiler, lumc.
I created lum because I had complaints about lua, namely a lack of +=, -=, and keywords making code long, like end and function.
Lum uses {} curly braces for blocks of code, and requires semicolons on each line.
To install, put lum.lua somewhere in your lua path, and put lumc somewhere in your executable path.
See example.lum for example lum code.
You can use lumc like this
# run a file
lumc filename.lum -r
# compile a file to lua
lumc filename.lum -o filename.lua
# preview generated lua code
lumc filename.lum
The lum library can be loaded from lua or lum using require.
Requiring the lum library gives you lum.loadfile, lum.dofile, lum.loadstring, lum.dostring, and the ability to require .lum files.
DEPENDENCIES:
lum.lua and lumc need to have lpeglabel installed. You can get lpeglabel with luarocks or something.
also, lumc is set up to run with luajit, but you can change it to whatever you want with the shebang.
I've only tested lum with 5.1 and luajit.
