Both versions will output the same code, and the C API (tolua++.h) is the +same. + +The build system is not yet ready to detect/decide when to compile for 5.1, +the easiest way right now is to add a file called 'custom.py' on the root of +the package, with the following: + +## BEGIN custom.py + +CCFLAGS = ['-I/usr/local/include/lua5.1', '-O2', '-ansi'] +LIBPATH = ['/usr/local/lib'] +LIBS = ['lua5.1', 'dl', 'm'] +tolua_bin = 'tolua++5.1' +tolua_lib = 'tolua++5.1' +TOLUAPP = 'tolua++5.1' + +## END custom.py + +This will build the binary as 'tolua++5.1' and the library as 'libtolua++5.1.a' +(taken from tolua_bin and tolua_lib), and take the lua headers and libraries +from /usr/local/include/lua5.1 and /usr/local/lib. It will also link with +'-llua5.1'. Modify the parameters acording to your system. + +Compatibility +------------- + +There are a couple of things to keep in mind when running code inside tolua +using the -L option: + +* `...' and arg: you can still use 'arg' on 5.1, this is done automatically by +adding the 'arg' declaration to functions on files loaded with dofile. + +For example, the line: + +function foo( ... ) + +becomes + +function foo( ... ) local arg = {n=select('#', ...), ...}; + +This lets you use the same code on both versions without having to make any +modifications. + +* keep in mind that there are slight differences on the way string.gsub works, +and the original version of the function is always kept, so it will behave +diffently depending on which version of lua you're using. -- cgit v1.2.3
