Ariadne is a Rust crate for producing fancy, colored compiler diagnostics and error reports with inline and multi-line labels, multi-file errors, and customizable output. It is a sister project of the Chumsky parser library and is now hosted on Codeberg.

Use cases

• report compiler errors with pretty source snippets
• show multi-line error spans in a Rust compiler
• print colored diagnostics to stderr for a parser
• generate multi-file error reports for an interpreter
• add nice error messages to a DSL toolchain
• write linter output with labeled source highlights

When to choose

• you are building a compiler, interpreter, parser, or linter in Rust and want high-quality error output
• you need multi-line and multi-file diagnostic labels with color support
• you want a generic diagnostics crate that works with custom span and cache types

When to avoid

• your project is not written in Rust
• you only need simple logging rather than source-annotated diagnostics
• you need diagnostics for a language with an existing mature tooling ecosystem
