musubi

Musubi (結び, "connection" in Japanese) is a high-performance diagnostics renderer
inspired by Rust's Ariadne library. It produces beautiful, color-coded diagnostic
messages with precise source location highlighting, multi-line spans, and intelligent
label clustering.

Features:
- Multi-line diagnostics with color-coded labels
- Intelligent label clustering and virtual row rendering
- Unicode and CJK character support (full-width characters, emoji, regional indicators)
- ASCII/Unicode glyph sets for terminal compatibility
- Line width limiting with smart truncation
- Customizable colors, character sets, and layout options
- Zero-copy source file handling with streaming support

This package provides C library with Lua bindings. A pure Lua implementation is also
available (ariadne.lua). For Rust users, see the musubi-rs crate on crates.io.
