Use parsers and queries in nvim-treesitter plugin

The Apex, SOQL, SOSL, and SFLog parsers in this repo are already part of nvim-treesitter repository. Any parser new version in this repo is automatically syned in nvim-treesitter.

Note. Nvim-treesitter maintains its own version of scm query files. It means that the query files stored in this repo is not used by nvim-treesitter.

How to install and use

Installing the nvim-treesitter plugin with whatever package manager you use. I use Lazy, and you can find my Nvim treesitter config here.

Once the plugin is installed, the parsers and query files are part of the plugin in your local installed version.

In your Nvim init configuraiton, you need to setup the filetypes so nvim-treesitter automatically kicks-in when corresponding filetypes are opened.

vim.filetype = on

vim.filetype.add({
  extension = {
    cls = 'apex',
    apex = 'apex',
    trigger = 'apex',
    soql = 'soql',
    sosl = 'sosl',
    log = 'sflog',
  }
})

Now when you open a .cls file, Nvim should use the Apex parser to parse the Apex language and highlights.scm to highlight syntax.

You may also want to check the sf.nvim which is a feature-rich Salesforce development plugin.

Troubleshoot

  1. Are the parsers successfully installed?

Run :TSInstallInfo to see the parser installation information

  1. No syntax highlight in Apex?

Sometimes the syntax higlight module is disabled, open an Apex file and run :TSEnable highlight to enable it.
