Editor setup

Chute provides extensions for VS Code and Neovim. Both extensions add syntax highlighting and connect to the Chute language server for diagnostics, completions, hover information, and definition lookup.

VS Code

Install the extension

Install Chute from the VS Code Marketplace. To install a local .vsix file, run:

code --install-extension chute-x.x.x.vsix

The extension starts when you open a .chute file. If the chute CLI isn't on your PATH, the extension displays installation instructions.

Features

• Syntax highlighting covers keywords, interpolated strings, types, declarations, and comments.
• Diagnostics display type errors and warnings in the editor.
• Completions include standard library actions after a module name and ., plus dot-name enum cases.
• Hover information shows action and function signatures with descriptions.
• Definition lookup opens function, action, and variable declarations.

Settings

Setting	Default	Description
chute.lsp.enabled	true	Enables or disables the language server.
chute.lsp.serverPath	""	Sets the path to the chute binary. An empty value uses chute from your PATH.
chute.trace.server	off	Sets the LSP trace level to off, messages, or verbose.

Neovim

Install Neovim 0.10 or later and nvim-treesitter before installing the Chute extension.

Install the extension

lazy.nvim

{
  "chutelang/chute",
  init = function(plugin)
    vim.opt.rtp:append(plugin.dir .. "/packages/chute.nvim")
  end,
}

vim-plug

Plug 'chutelang/chute', { 'rtp': 'packages/chute.nvim' }

After you install the plugin, run :TSInstall chute to install the Tree-sitter parser.

Features

• Tree-sitter highlights keywords, types, declarations, interpolated strings, enum cases, and special variables such as #index.
• The Chute language server provides diagnostics, completions, hover information, and definition lookup when you open a .chute file.
• The plugin configures code folding and indentation.
• Text objects select syntax units such as a function body.
• Filetype detection configures two-space indentation and // comments for .chute files.

Configuration

Set vim.g.chute_cmd to a custom path if chute isn't on your PATH:

vim.g.chute_cmd = "/usr/local/bin/chute"

Health check

Run :checkhealth chute to check the chute binary and Tree-sitter parser.
