[ANN] Grace 0.2.0 💅, fancy diagnostics library for compilers

[Alistair]

I’m excited to announce the release of grace 0.2.0, an OCaml library for building, reporting and rendering beautiful compiler diagnostics . Now available on opam-repository.

The three main features of this release include:

• UTF8 support: Source files can now contain Unicode characters, including emojis , with proper rendering of ASCII art for errors.

• Error Codes: Diagnostics can now include short, searchable error codes. Allowing compilers to integrate a Rust-like error code index.

• Compact ANSI Errors: Grace_ansi_renderer now supports a pp_compact_diagnostic for concise error messages, displaying only the file location and the error message.

Tap into the power of Grace for your error reporting! Happy hacking

CHANGES:

• fix(renderer): remove uncessary underlines when printing a unique ‘multi-line Top marker’ (#31)
• fix(renderer): replace unicode chars with ASCII in Config.ascii (#27)
• feat(renderer): add NO_COLOR and TERM support to Config (#8)
• feat(core,renderer): add support for error codes (#30)
• feat(renderer): add support for UTF8 encoding (#25)
• feat(renderer): re-introduce support for compact diagnostic rendering (#28)
• refactor(renderer)!: move grace.renderer library to grace.ansi_renderer (#29)

BREAKING CHANGE

• Grace_rendering has been removed. Use Grace_ansi_renderer instead.

This looks very promising, and very frustrating at the same time because I can’t compile it on windows yet (not the library itself, but I can’t get the dependencies yet).

I’ve seen you are planning to provide LSP integration? This would be fantastic to have a single library for managing all the error reports!

Just makes me wish I could have Unicode characters in OCaml source files for identifiers & operators in OCaml
