🧾 contenty

A tiny Gleam library for parsing and inspecting HTTP Content-Type headers.

✨ Features

• Parses Content-Type strings into a structured, opaque ContentType value
• Handles parameters like charset, boundary, version, etc.
• Ignores malformed parameters safely
• Case-insensitive, whitespace-tolerant, and RFC-aware
• No dependencies beyond the Gleam standard library

Installation

gleam add contenty

import contenty
import gleam/result
import gleam/dict

pub fn main() {
  let content_type = contenty.parse("text/html; charset=utf-8")

  contenty.mime(content_type)
  // "text/html"

  contenty.mime_type(content_type)
  // "text"

  contenty.mime_subtype(content_type)
  // "html"

  contenty.param(content_type, "charset")
  // Ok("utf-8")

  contenty.params(content_type)
  // dict.from_list([#("charset", "utf-8")])
}
