Description

This library contains a database of MIME types that maps filename extensions into MIME types suitable for use in many Internet protocols such as HTTP or e-mail. It is generated from the mime.types file found in Unix systems, but has no dependency on a filesystem since it includes the contents of the database as an ML datastructure.

For example, here's how to lookup MIME types in the [utop] REPL:

#require "magic-mime";;
Magic_mime.lookup "/foo/bar.txt";;
- : bytes = "text/plain"
Magic_mime.lookup "bar.css";;
- : bytes = "text/css"

magic-mime -- map filenames to common MIME types

This library contains a database of MIME types that maps filename extensions into MIME types suitable for use in many Internet protocols such as HTTP or e-mail. It is generated from the mime.types file found in Unix systems, but has no dependency on a filesystem since it includes the contents of the database as an ML datastructure.

For example, here's how to lookup MIME types in the utop REPL:

Magic_mime.lookup "/foo/bar.txt";;
- : bytes = "text/plain"
Magic_mime.lookup "bar.css";;
- : bytes = "text/css"

Internals

The following files need to be edited to add MIME types:

  • mime.types: this is obtained by syncing from the Apache Foundation's mime.types in the Apache Subversion repository.

  • x-mime.types: these are the extension types, so non-standard x- prefixes are used here.

  • file.types: full filenames of common occurrences that are useful to map onto a MIME type. OCaml-specific things like opam files show up here.
