OpenFOAM grammar for Tree-Sitter

This project is in early phases of development; expect things to change considerably

DISCLAIMER: This offering is not approved or endorsed by OpenCFD Limited, producer and distributor of the OpenFOAM software and owner of the OPENFOAM® and OpenCFD® trade marks.

This is a generic fail-tolerant parser for OpenFOAM case dictionaries. The goal is to reach a state that is "good enough" for syntax highlighting and feasible symbols extraction.

Features

• Semantic understanding of OpenFOAM IO entries (Dictionaries, key-value pairs, ... etc)
• Syntax highlighting (Targeting nvim-treesitter mainly)
• Highlighting of C++ code blocks and regular expressions, so if your client does not install those parsers automatically, you might have to install them manually
• Scope-awareness is there (Per-dictionary) although not used yet
• Text-objects for dictionaries and key-value pairs to use with TreeSitter textobjects plugin for NeoVim
• Text-subjects to use with TreeSitter textsubjects plugin for NeoVim
• Expression-based folding

Running tests

• Unit tests for both parsing and highlighting (Highlighting is not consistent between tree-sitter highlight and nvim-treesitter) are executed with tree-sitter test (Check the test folder)
• testOFFiles.sh $FOAM_TUTORIALS parses all OpenFOAM dictionaries in the tutorials directory
  • Currently, the parser works on almost all OpenFOAM 8 and Foam-Extend 4 tutorial files (Well, some files are faulty from source!)

Contributing

• Pull requests are welcome!
• And, no I'm not going to support specific keyword highlighting (eg. scalarField will never be treated in a special way) unless I find an "unattended" way to do that.
