Nvim Treesitter

Treesitter provides language specific parsing, highlight and indent features and so is a fundamental plugin to use with Neovim.

clojure, fennel, markdown and org parsers are automatically installed in the practicalli/neovim-config-redux configuration.

• :TSInstallInfo lists language parsers and install status
• :TSUpdate {language} to update a parser to the latest compatible version (specified in nvim-treesitter lockfile.json).
• :TSInstall {language} compiles and installs a parser for the given language.
• :TSUpdateSync to update all parsers to the latest available versions

nvim-treesitter configuration

clojure, fennel, markdown and org parsers are automatically installed if not already available.

:sync_install true automatically updates the parsers when the nvim-treesitter plugin is updated. Treesitter and its parsers are actively developed, so its important to ensure parsers are kept up to date. This is the equivalent of manually running :TSUpdateSync.

Parser highlight and indent modules are enabled by default

In fnl/config/plugin/treesitter.fnl

(module config.plugin.treesitter
  {autoload {treesitter nvim-treesitter.configs}})

(treesitter.setup
  {:ensure_installed ["clojure" "fennel" "markdown" "org"]
   :sync_install true
   :highlight {:enable true}
   :indent    {:enable true}})

Manually Install Parsers

nvim-treesitter provides the TSInstall command to generate a parser for a specific language, assuming that language is supported.

A compiler (gcc, clang, etc) should be installed in the operating system on which nvim is running

:TSInstall {language}

TAB completion lists the available language parsers, TAB and S-TAB to navigate the auto-completion popup.
