26 To compile a lua script to bytecode (luac) run:
27 vlc -I lua --lua-intf --lua-config 'luac={input="file.lua",output="file.luac"}'
28 Output will be similar to that of the luac command line tool provided with lua with the following arguments:
29 luac -o file.luac file.lua
36 vlc.msg.info("About to compile lua file")
37 vlc.msg.info(" Input is '"..tostring(config.input).."'")
38 vlc.msg.info(" Output is '"..tostring(config.output).."'")
39 if not config.input or not config.output then
40 vlc.msg.err("Input and output config options must be set")
44 local bytecode, msg = loadfile(config.input)
46 vlc.msg.err("Error while loading file '"..config.input.."': "..msg)
50 local output, msg = io.open(config.output, "wb")
52 vlc.msg.err("Error while opening file '"..config.output.."' for output: "..msg)
55 output:write(string.dump(bytecode))
