local DIRSEP = package.config:sub(1,1) -- handle Windows or Unix
function listfiles(dir,list)
list = list or {} -- use provided list or create a new one
for entry in lfs.dir(dir) do
if entry ~= "." and entry ~= ".." then
local ne = dir .. DIRSEP .. entry
if lfs.attributes(ne).mode == 'directory' then
listfiles(ne,list)
else
table.insert(list,ne)
end
end
end
return list
end
for _,n in ipairs(listfiles(".")) do
print(n)
end
