This crate contains the comment function, which turns the passed input into a comment for the given file type

use commented::comment;

assert_eq!(comment("hello, world!", "index.html"), "<!-- hello, world! -->");
assert_eq!(comment("hello, world!", "main.rs"), "/* hello, world! */");
assert_eq!(comment("hello, world!", "script.lua"), "--[[ hello, world! --]]");

// files without an extension
assert_eq!(comment("hello, world!", "123456789"), "# hello, world!");
