git2codeblock is a crate that converts git URLs into codeblocks. This is mainly for use in one of my Discord bots, but is written to be used anywhere.
Given the url: https://gitlab.com/ewpratten/DeepSpace/-/blob/master/CODEOWNERS#L2, git2codeblock will realize that this is GitLab, correctly process the file, and return a Markdown fenced codeblock.
let url = "https://gitlab.com/ewpratten/DeepSpace/-/blob/master/CODEOWNERS#L2";
let codeblock = git2codeblock::extract_codeblock(url).await.unwrap();
assert_eq!(codeblock, "```\n* @ewpratten @slownie @johnlownie @LordMichaelmort @awpratten\n```");
