mime

MIME parsing and rendering helpers.

mime is a focused package for dealing with media types, parameters, and MIME syntax. It is useful anywhere Riot code needs to understand or produce content types cleanly instead of passing raw strings around.

Install

riot add mime

Typical uses

  • parsing Content-Type headers in HTTP code;
  • rendering MIME values back to strings;
  • working with parameters such as charset=utf-8 or multipart boundaries;
  • centralizing MIME handling in clients, servers, and tooling.

Example

open Std
open Mime

let headers = [
  ("Content-Type", "text/plain");
  ("Content-Transfer-Encoding", "base64");
] in

let body = "SGVsbG8gV29ybGQ=" in

match Mime.parse ~headers ~body with
| Ok (SinglePart part) ->
    let decoded = Mime.get_decoded_content part |> Result.expect ~msg:"example should decode" in
    println decoded
| Ok (MultiPart _) ->
    panic "expected a single part"
| Error err ->
    panic err

A runnable example is included:

riot run -p mime decode_attachment

Where to look next

  • src/Mime.mli is the public API.
  • tests/rfc2231_tests.ml covers parameter-handling edge cases.
  • the RFC notes in src/ explain the standards the implementation is following.
