go-emoji-shortcode

go-emoji-shortcode is a small, dependency-free Go library for mapping emoji shortcodes like :smile: and :wave: to Unicode emoji characters. It was extracted from matcha so that other Go projects can add emoji preview and suggestion support without dragging in a heavy emoji database or external dependencies.

What it does

• Lookup — convert a shortcode to an exact emoji character.
• Suggest — fuzzy-match shortcodes for a prefix, e.g. sm returns smile, smirk, etc.
• All — enumerate every known shortcode/emoji pair.

The library ships with ~1900 shortcodes generated from GitHub's gemoji database, so the names are the ones users already know from GitHub, Slack, Discord and many other apps.

Use cases

• Live emoji picker in a text editor or TUI composer.
• Autocomplete in chat apps, comment boxes, or wiki inputs.
• Rendering :shortcode: text into actual emoji in Markdown or email bodies.
