Hi,
Has anyone written a Lua module for reading ID3 tags (both v1 and v2) in
MP3 files? If not, I may translate one of the available Python modules.
I wrote a tiny binding for id3lib for Lua 5.0 or 5.1. Now I
don't use it anymore. I simply use os.execute and get the
tags directly from "id3v2 --list". Sure, for images etc this
might not work. But for text it works just fine.
-- non-optimized kludge follows
function id3.read(f)
local f = io.popen("id3v2 --list '" .. f .. "'")
local s = f:read("*a")
f:close()
-- kill header
s = string.gsub(s, "^.-id3v2.-\n", "")
local t = {}
string.gsub(s, "(.-)%s+.-:%s+(.-)\n", function(a, b, c)
t[a] = c
end)
return t
end
If you have a decent bind, I guess I would use it instead. :)
If you want my old bind, I can send it to you.
[]s,
Diego
