mimetypes.lua Version 1.0.0
This is just a quick Lua library designed to provide a nice, non-server-bound database of MIME types. Usage is simple:
local mimetypes = require 'mimetypes'
mimetypes.guess "docs.txt" -- text/plain
mimetypes.guess "word.doc" -- application/msword
mimetypes.guess "init.lua" -- text/x-lua
Should you need your own MIME types, you can do this:
local mimedb = mimetypes.copy()
mimedb.extensions["ext"] = "application/x-cool-type"
mimetypes.guess("myfile.ext", mimedb) -- application/x-cool-type
If you want to make sure it works, run
lua test.lua(or use Shake).
mimetypes.copy([db])- Copies the default MIME types database and returns the copy. If you provide
db, it is copied instead of the default.
mimetypes.guess(filename[, db])- Guesses the MIME type of the file named
filename. If a MIME type could not be ascertained, nil is returned. If you provide
db, it is used to look up the MIME type instead of the default database.
Each database is a table that contains two fields -
filenamesis checked first, as it maps literal filenames (like
README) to MIME types.
If that doesn't work, the file's extension is taken and looked up in
extensions. (For example,
report.pdfwould look up
The default database is immutable (and hidden), because it's shared between everyone who calls
guesswithout arguments, and messing with it would be a bad thing.
