패키지 설치 및 사용례

  • 패키지는 http://luarocks.org 참조 - 각 모듈 다운로드 순위도 참고

  • 실제 사용례 ```console $ luarocks search luafilesystem $ luarocks install –local luafilesystem $ luarocks list $ luarocks show luafilesystem $ vim attrdir.lua

#!/usr/bin/env lua local lfs = require”lfs” – import luafilesystem module

function attrdir (path) for file in lfs.dir(path) do if file ~= “.” and file ~= “..” then local f = path..’/’..file print (“\t “..f) local attr = lfs.attributes (f) assert (type(attr) == “table”) if attr.mode == “directory” then attrdir (f) else for name, value in pairs(attr) do print (name, value) end end end end end

attrdir (“.”)

$ chmod u+x attrdir.lua $ ./attrdir.lua ```
