discord-md

Parser and generator for Discord's markdown, written in Rust

Example

Parsing

use discord_md::ast::*;
use discord_md::parse;

fn main() {
  let message = "You can write *italics text*, `*inline code*`, and more!";

  let ast = MarkdownDocument::new(vec![
    MarkdownElement::Plain(Box::new(
      Plain::new("You can write ")
    )),
    MarkdownElement::ItalicsStar(Box::new(
      ItalicsStar::new(vec![
        MarkdownElement::Plain(Box::new(
          Plain::new("italics text")
        ))
      ])
    )),
    MarkdownElement::Plain(Box::new(
      Plain::new(", ")
    )),
    MarkdownElement::OneLineCode(Box::new(
      OneLineCode::new("*inline code*")
    )),
    MarkdownElement::Plain(Box::new(
      Plain::new(", and more!")
    )),
  ]);

  assert_eq!(
    parse(message),
    ast
  );
}

Generating

use discord_md::ast::MarkdownDocument;
use discord_md::builder::*;

fn main() {
  let ast = MarkdownDocument::new(vec![
    plain("generating "),
    one_line_code("markdown"),
    plain(" is "),
    underline(vec![
      bold("easy"),
      plain(" and "),
      bold("fun!"),
    ]),
  ]);

  assert_eq!(
    ast.to_string(),
    "generating `markdown` is __**easy** and **fun!**__"
  );
}

Features

• Minimal dependencies (only nom and derive_more)
• Supports the following syntax:
  • Italics (*italics*, _italics_)
  • Bold (**bold**)
  • Underline (__underline__)
  • Strikethrough (~~strikethrough~~)
  • Spoiler (||spoiler||)
  • One line code (`one line code`)
  • Multi line code

    ```sh
    echo "multi line"
    echo "code"
    ```
    

  • Block Quote (generator only)

    > block quote
    > some text

Parser limitations

The parser tries to mimic the behavior of the official Discord client's markdown parser, but it's not perfect. The following is the list of known limitations.

• Block quotes are not parsed. > will be treated as plain text.
• Nested emphasis, like *italics **bold italics** italics*, may not be parsed properly.
• Intraword emphasis may not be handled properly. The parser treats foo_bar_baz as emphasis, while Discord's parser does not.
• Escaping sequence will be treated as plain text.
