tree-sitter-pact

tree-sitter grammar for pact smart contract language

Neovim setup (WIP)

I will create a PR to add this to the official nvim-treesitter repo once it's ready, for now you can use it by following these steps:

Clone the repo

git clone https://github.com/kadena-community/tree-sitter-pact.git

Add those to your init.lua

vim.filetype.add({
  extension = {
    pact = "pact",
    repl = "pact",
  },
})
local parser_config = require("nvim-treesitter.parsers").get_parser_configs()
parser_config.pact = {
  install_info = {
    url = "~/path/to/c/tree-sitter-pact",
    files = { "src/parser.c" },
  },
  filetype = "pact",
}

Then run :TSInstall pact in neovim.

also you need to link the queries folder to your nvim config folder

mkdir -p ~/.config/nvim/after/queries/pact
ln ./queries/highlights.scm ~/.config/nvim/after/queries/pact/highlights.scm
ln ./queries/locals.scm ~/.config/nvim/after/queries/pact/locals.scm
ln ./queries/textobjects.scm ~/.config/nvim/after/queries/pact/textobjects.scm
ln ./queries/folds.scm ~/.config/nvim/after/queries/pact/folds.scm
ln ./queries/indents.scm ~/.config/nvim/after/queries/pact/indents.scm

Testing

To run the tests for the core grammar, you need to have tree-sitter-cli installed. You can install it with npm:

npm install -g tree-sitter-cli

Then, run the following command from the root of the repository:

npx tree-sitter generate && npx tree-sitter build && npx tree-sitter test

Language Bindings

To run the tests for the language bindings, you will need to have the respective toolchains installed (e.g., Python, Go, Swift, Rust).

• Rust:

  cargo test
  

• Swift:

  swift test
  

• Go:

  cd bindings/go
  go get -t
  go test -v
  

• Python: First, create and activate a virtual environment:

  python -m venv .venv
  source .venv/bin/activate
  

  Then, install the package in editable mode with its core dependencies:

  pip install -e ".[core]"
  

  Finally, run the tests:

  python -m unittest discover -v -s bindings/python/tests
  

• Nodejs

  node bindings/node/binding_test.js
  // or
  npm run test
