my variant. much simpler, but doesn't handle alternative separators:
-- OS-dependent directory separator
DIR_SEPARATOR = "\\"
-- Return filename directory: c:\dir\file.ext -> c:\dir
function get_dir(filename)
return (string.match (filename, "(.*)"..DIR_SEPARATOR..".+"))
end
-- Return filename without directory: c:\dir\file.ext -> file.ext
function drop_dir(filename)
return (string.match (filename, ".*"..DIR_SEPARATOR.."(.+)"))
end
-- Return extension: file.ext -> ext
-- Filename passed shouldn't contain path!
function get_ext(filename)
return string.match (filename, ".+[.](.*)") or ""
end
-- Drop extension: file.ext -> file
-- Filename passed shouldn't contain path!
function drop_ext(filename)
return string.match (filename, "(.+)[.].*") or filename
end
