If an open source Tree-sitter parser is available, we can run
./vendor.sh download
to download the C code thats needed to add a grammar.I'm using serenadeai/tree-sitter-scss to add the SCSS grammar.
One time updates
The
vendor.sh
script is using features from the latest version of Bash. MacOS includes an older version of Bash so I updated my system to v5.Per Grammar
Update vendor script
Add grammar: name; version / tag of repo to download; files to download
["scss"]="v1.0.0;parser.c;scanner.c"
Add repository
["scss"]="serenadeai/tree-sitter-scss"
Download C code
From root of repo run:
./vendor.sh download
Add Go binding
In new grammar directory add:
binding.go
binding_test.go
Run your test to verify the new grammar works!
