nvim-biscuits

Every dev needs something sweet sometimes. Code Biscuits are in-editor annotations usually at the end of a closing tag/bracket/parenthesis/etc. They help you get the context of the end of that AST node so you don't have to navigate to find it.

Installation

In your nvim config, add the Plug dependencies:

call plug#begin()
Plug 'nvim-treesitter/nvim-treesitter', {'do': ':TSUpdate'}
Plug 'code-biscuits/nvim-biscuits'
call plug#end()

You will also need to configure which language parsers you want to have enabled for tree-sitter. "maintained" currently will install 40 languages. "all" will install even more.

lua <<EOF
require'nvim-treesitter.configs'.setup {
  ensure_installed = "maintained",
  ...
}
EOF

Configuration

Basic configuration is simple:

lua require('nvim-biscuits').setup({})

You can also configure your own global defaults as well as language specific defaults.

This is just an example config.

lua <<EOF
require('nvim-biscuits').setup({
  default_config = {
    max_length = 12,
    min_distance = 5,
    prefix_string = " 📎 "
  },
  language_config = {
    html = {
      prefix_string = " 🌐 "
    },
    javascript = {
      prefix_string = " ✨ ",
      max_length = 80
    },
    python = {
      disabled = true
    }
  }
})
EOF

Configuration (Custom events)

If you want to decorate only on specific vim events you can use the on_events config option. It is a string that takes in a comma separated list of vim autocmd events (http://vimdoc.sourceforge.net/htmldoc/autocmd.html#autocmd-events)

This example only updates the biscuits when leaving insert mode or hold the cursor in one place for long enough.

lua <<EOF
require('nvim-biscuits').setup({
  on_events = { 'InsertLeave', 'CursorHoldI' }
})
EOF

Configuration (Virtual Text Color)

You can configure the highlight group in your init.vim:


" global color
highlight BiscuitColor ctermfg=cyan

" language specific color
highlight BiscuitColorRust ctermfg=red

Configuration (Disabling Languages)

You may have tree-sitter set up for some languages in which you don't want nvim-biscuits to show up. Since we just use whatever supported languages tree-sitter has by default, you must disable languages individually.

To disable nvim-biscuits for any language, simply add { mylanguage = {disabled = true} } to language_config field in setup. (where mylanguage is the language that you want to disable. eg: python, dart, etc)

Configuration (Trim by words)

Using this settings, you can dictate the max length of a biscuit using whole words rather than just characters. The max_length determines how many words will show when this setting is enabled.

lua <<EOF
require('nvim-biscuits').setup({
  max_length = 2,
  trim_by_words = true,
})
EOF

Configuration (Keybinding to toggle visibility)

You can show or hide the biscuits by placing a toggle_keybind at the root of your config or inside a language config.

lua <<EOF
require('nvim-biscuits').setup({
  toggle_keybind = "<leader>cb"
})
EOF

OR

lua <<EOF
require('nvim-biscuits').setup({
  language_config = {
    rust = {
      toggle_keybind = "<leader>cb"
    }
  }
})
EOF

If you prefer to bind manually, the function is exposed as:

require('nvim-biscuits').toggle_biscuits()

Configuration (Cursor Line Only)

You can configure the biscuits to only show on the line that has your cursor. This can be useful if you find that default config makes the text too cluttered

lua <<EOF
require('nvim-biscuits').setup({
  cursor_line_only = true
})
EOF

Supported Languages

We currently support all the languages supported in tree-sitter. Not all languages have specialized support, though most will probably need some.

As we make tailored handlers for specific languages we will create a table here to track that.

Development

While doing local dev, it can be nice to use the utils.console_log command to write runtime logs to ~/vim-biscuits.log.

You can turn this on by passing DEBUG=true as an environment variable when launching Neovim.
