MODULES *nvim-treesitter-modules*
|nvim-treesitter| provides several functionalities via modules (and submodules),
each module makes use of the query files defined for each language,
you can add your own queries too, see |nvim-treesitter-query-extensions|.
All modules are disabled by default, and some provide default keymaps.
Each module corresponds to an entry in the dictionary passed to the
`nvim-treesitter.configs.setup` function, this should be in your `init.vim` file.

All modules share some common options, like `enable` and `disable`.
When `enable` is `true` this will enable the module for all supported languages,
if you want to disable the module for some languages you can pass a list to the `disable` option.

keymaps in Neovim, so you can write keymaps as `gd`, `<space>a`, `<leader>a`
`<C-a>` (control + a), `<A-n>` (alt + n), `<CR>` (enter), etc.
External plugins can provide their own modules with their own options,
those can also be configured using the `nvim-treesitter.configs.setup`
function.
