Tree-sitter parser for Koto.
The justfile contains some commands that are
useful during development, in particular just test which will generate the
tree-sitter parser from grammar.js and then run the tests
contained in test/corpus.
just watch test will re-run just test when files are updated.
Arguments can be passed to just watch test,
e.g. just watch test --debug -f identifiers will generate the parser with
debug logging enabled, and then run only the identifiers test.
src/scanner.c contains the external scanner used
by the grammar, handling some of the more complex aspects of parsing Koto code.
Debug logging for the scanner can be enabled via a preprocesser definition at the
top of the file.
