Emoji Extractor

Overview

This skill provides a workflow and tools to extract emoji glyphs from font files and save them as standalone SVG files. It uses a Node.js script to parse the font and generate the SVG path.

When to Use

• You need an SVG version of a specific emoji.
• You have a font file (or URL to one) and want to extract one or more glyphs from it.
• Note: Works best with standard outline fonts (e.g. NotoEmoji-Regular). Color bitmap fonts (like NotoColorEmoji) might not be fully supported or may fail to yield vector paths.
• You want consistent emoji assets across different platforms by embedding them as SVGs.

Usage

Prerequisites

• Node.js installed.
• Dependencies installed in the scripts directory (run npm install in .agent/skills/emoji-extractor/scripts).

Extraction Command

Use the extract_emoji.js script to extract emojis.

node .agent/skills/emoji-extractor/scripts/extract_emoji.js --font <path_to_font> --emoji <emoji_list> --out <output_file_or_dir> [--force]

Arguments:

• --font: Path to local font OR URL. URL fonts are cached in tmp/fonts_cache/ to avoid repeated downloads.
• --emoji: Comma-separated list of emojis (e.g. "🔥, 🚀") or unicode hex codes.
• --out: Output directory (recommended for batch) or file path.
• --force: Overwrite existing files (default: skip if exists).

Examples

Extract 'Fire' emoji from local Noto font:

node .agent/skills/emoji-extractor/scripts/extract_emoji.js --font "assets/fonts/NotoColorEmoji.ttf" --emoji "🔥" --out "assets/emoji/fire.svg"

Extract 'Rocket' emoji from URL:

node .agent/skills/emoji-extractor/scripts/extract_emoji.js --font "https://example.com/fonts/NotoEmoji-Regular.ttf" --emoji "🚀" --out "assets/emoji/"
