Some languages, like C or C++, use a preprocessor to implement such
features. The compiler itself takes its translations units whole and
consistent, just like Lua. I believe you can use existing
preprocessors (m4, gcc -E, etc.) and apply them to Lua source files.
I wrapped the mcpp preprocessor [1] as a Lua module. You can find it
here [2].
An example:
function preprocess(filename, defines, includes)
require 'mcpp'
local mcppInput = {}
mcppInput[#mcppInput + 1] = "-P"
mcppInput[#mcppInput + 1] = filename
for _, define in ipairs(defines) do
mcppInput[#mcppInput + 1] = "-D"
mcppInput[#mcppInput + 1] = define
end
for _, includeDirectory in ipairs(includes) do
mcppInput[#mcppInput + 1] = "-I"
mcppInput[#mcppInput + 1] = includeDirectory
end
return mcpp.preprocess(mcppInput)
end
