Progress: Grammar::Modelica

Current status

Docker-based local testing and Docker-backed GitHub Actions CI are in place, module packaging has been modernized to .rakumod, and the grammar has now been aligned with key Modelica 3.6 concrete syntax updates.

What works

• Raku module files under lib/ now use .rakumod extensions instead of .pm6.

• META6.json provides entries now explicitly map all modules to .rakumod paths.

• README repository layout now references lib/Grammar/Modelica.rakumod.

• Docker test image support via Dockerfile and .dockerignore.

• Convenience commands via Makefile targets:

  • docker-build

  • docker-test

  • docker-shell

• GitHub Actions workflow (.github/workflows/ci.yml) that builds and runs tests in Docker.

• README documentation for Docker usage and CI status badge.

• Modelica 3.6 grammar alignment updates completed in parser code:

  • Added description / description_string productions.

  • Kept comment / string_comment as compatibility aliases.

  • Added function_partial_application and integrated it in function-argument grammar.

  • Updated import_clause to explicitly allow name.* / name .* form.

  • Updated class grammar rules to use description naming.

• Test coverage updated for 3.6-oriented behavior in:

  • t/ClassDefinition.t

  • t/Expressions.t

• Dockerized test suite currently passes:

  • docker build --no-cache --progress=plain -t grammar-modelica-test .

  • docker run --rm grammar-modelica-test

What remains

• Optionally pin rakudo-star to a specific version tag for stronger reproducibility.

• Optionally remove/retire legacy CI files (.travis.yml, appveyor.yml) once migration is fully validated.

• Continue parser modernization tasks from projectbrief.md (extensions, parser optimization, actions, metadata updates).

Known issues

• raku, prove, and make are still unavailable on PATH in the current shell; Docker remains the validated execution path in this environment.

Recent evolution

• Migrated module files and META6.json mappings from deprecated .pm6 usage to modern .rakumod usage to address deprecation warnings.

• Added first-class Docker workflow for local tests.

• Migrated active CI path to GitHub Actions using Docker-based execution.

• Synced implemented grammar portions from Modelica 3.4 to 3.6 concrete syntax for:

  • description/comment production naming,

  • function partial application production support,

  • explicit import wildcard tokenization (.*).
