Flare is a syntax highlighting library built using the incremental parser GPeg.

Features:

• Supports fast incremental rehighlighting for use in an editor.
• Can load and use highlighters at runtime.
• Multiple languages are supported, and it is easy to add more (check the languages/ directory).
• Supports limited context-sensitivity (back references) for handling HERE-doc style blocks.
• Supports including languages within each other.
• Fairly efficient.
• Can format highlighted code as HTML output.

See the flare program in ./cmd/flare for an example that can highlight code files at the terminal or output highlighted HTML.
