This Visual Studio Code extension provides syntax highlighting for R and R Markdown extensions.

It brings more consistency with other VS Code language syntaxes (such as Python and C) and Sublime Text R syntax.

It only contains syntax definitions to allow users to switch to alternative formatters and language servers such as air and ark.

The releases are available in VSCode Marketplace or Open VSX Registry. Search for extension "R Syntax".

If you are interesting in contributing to the syntaxes, feel free to clone the repository and edit the r.yaml and rmd.yaml files under the syntaxes directroy. In order to build the json files, you will need to install node.js and run

npm install
npm run build
# or the following if you want to build the json files in watch mode
npm run build -- --watch

You should also run the grammar tests located in the tests/testdata. See vscode-tmgrammar-test for details.

npm run test:grammar
# or the following if you want to test in watch mode
npm run test:grammar -- --watch
