Community

Iā€™m excited to announce the release of grace 0.3.0, an OCaml library for building, reporting and rendering beautiful compiler diagnostics :camel: :paintbrush:. Now available on opam-repository.

This release includes:

  • :window: Windows support: Grace now works on Windows, a long-awaited feature since its 0.1.0 release! :rocket:

  • :keyboard: TTY auto-detection: Grace_ansi_renderer can now automatically configure itself based on whether the output channel is a TTY. New functions: pr_diagnostic, epr_diagnostic, and output_diagnostic.

  • :elephant: Line elision: Grace_ansi_renderer now elides unnecessary lines in diagnostics, producing more focused output.

  • :zero: Zero-width ranges: Grace_ansi_renderer can now handle zero-width ranges within lines, as well as at end-of-line (EOL) and end-of-file (EOF) positions.

Many thanks to @giltho for their contributions to this release! :flexed_biceps:
