🎯 How It Works

Enhanced Keyword Matching Strategy

1. 🔍 Analysis: Commit message analyzed word by word
2. 🧹 Cleaning: Non-alphanumeric characters replaced with spaces for better word extraction
3. 📝 Extraction: Words split by whitespace and normalized to lowercase
4. 🎯 Matching: First word matched against comprehensive keyword database
5. ✨ Formatting: Complete commit message formatted with appropriate gitmoji

Keyword Categories

Architecture

The tool uses a clean strategy pattern with pluggable matchers:

pub trait GitmojiMatcher {
    fn match_emoji(&self, message: &str) -> Result<MatcherResult>;
    fn name(&self) -> &'static str;
}

pub type MatcherResult = Option<(String, String)>; // (emoji_code, formatted_message)

Current Matchers:

• SimpleMatcher: Keyword-based matching with 200+ keywords
• LLMMatcher: AI-powered matching (optional feature)
