Goals
- Treesitter grammars
- Code highlighting, different schemes
- prettfying like carbon
- annotate
- spans with messages
- regions/scopes
- multi-part regions
- relate regions with arrows
- "annotate every line" explainers
- running code, annotate variables with values
- annotate based on nameres
- compiler output, error messages, expected error messages
- integrate with lsp; again....
- all metadata in source code
- intra-body arrows, graph layout
- export to
- rich text for slides
- terminals
- html
- PDF/typst?
Plan
- Architecture with different backends
- Treesitter parsers
- data format for arbitrary ASTs
- separate algorithms:
- highlighting
- graph layout
