# Modula-2 Language Support

GNU Modula-2 language support for VS Code and Theia: syntax
highlighting for `.mod`/`.def`, snippets, auto-uppercasing,
Outline, hover, go-to-definition, references, rename, formatting and
semantic tokens — backed by a Coco/R-validated language server
(`gm2` grammar) plus always-on local analysis.

## Requirements

Editing features work out of the box. External validator
diagnostics need a Coco/R validator binary (see `COCOR-LSP.md`)
configured via `modula2.cocoR.validatorCommand`; `gm2`, `gdb` and
`readelf` remain host prerequisites for compiling and debugging.

## Settings

- `modula2.uppercaseKeywords` — uppercase keywords while typing.
- `modula2.format.*` — formatter rules (indent, keyword case, spacing).
- `modula2.cocoR.validatorCommand` / `validatorArguments` — external
  Coco/R validator.
