Features

  • Highlight text with configurable patterns and highlight groups (can be string or callable).

  • Highlighting is updated asynchronously with configurable debounce delay.

  • Function to get matches in a buffer.

See *MiniHipatterns-examples* tag in help page for examples of common use cases.

Notes:

  • It does not define any highlighters by default. Add to config.highlighters to have a visible effect.

Example usage

local hipatterns = require('mini.hipatterns')
hipatterns.setup({
  highlighters = {
    -- Highlight standalone 'FIXME', 'HACK', 'TODO', 'NOTE'
    fixme = { pattern = '%f[%w]()FIXME()%f[%W]', group = 'MiniHipatternsFixme' },
    hack  = { pattern = '%f[%w]()HACK()%f[%W]',  group = 'MiniHipatternsHack'  },
    todo  = { pattern = '%f[%w]()TODO()%f[%W]',  group = 'MiniHipatternsTodo'  },
    note  = { pattern = '%f[%w]()NOTE()%f[%W]',  group = 'MiniHipatternsNote'  },

    -- Highlight hex color strings (`#rrggbb`) using that color
    hex_color = hipatterns.gen_highlighter.hex_color(),
  },
})

Installation

This plugin can be installed as part of 'mini.nvim' library (recommended) or as a standalone Git repository.

There are two branches to install from:

  • main (default, recommended) will have latest development version of plugin. All changes since last stable release should be perceived as being in beta testing phase (meaning they already passed alpha-testing and are moderately settled).
  • stable will be updated only upon releases with code tested during public beta-testing phase in main branch.

Here are code snippets for some common installation methods (use only one):

With mini.deps
Github repo Branch Code snippet
'mini.nvim' library Main Follow recommended 'mini.deps' installation

Stable add({ source = 'echasnovski/mini.hipatterns', checkout = 'stable' })
With folke/lazy.nvim
Github repo Branch Code snippet
'mini.nvim' library Main { 'echasnovski/mini.nvim', version = false },

Standalone plugin Main { 'echasnovski/mini.hipatterns', version = false },
Stable { 'echasnovski/mini.hipatterns', version = '*' },
With junegunn/vim-plug
Github repo Branch Code snippet
'mini.nvim' library Main Plug 'echasnovski/mini.nvim'
Stable Plug 'echasnovski/mini.nvim', { 'branch': 'stable' }
Standalone plugin Main Plug 'echasnovski/mini.hipatterns'
Stable Plug 'echasnovski/mini.hipatterns', { 'branch': 'stable' }

Important: don't forget to call require('mini.hipatterns').setup() with non-empty highlighters to auto-enable highlighting in all normal buffers.

Note: if you are on Windows, there might be problems with too long file paths (like error: unable to create file <some file name>: Filename too long). Try doing one of the following:

  • Enable corresponding git global config value: git config --system core.longpaths true. Then try to reinstall.
  • Install plugin in other place with shorter path.

Default config

-- No need to copy this inside `setup()`. Will be used automatically.
{
  -- Table with highlighters (see |MiniHipatterns.config| for more details).
  -- Nothing is defined by default. Add manually for visible effect.
  highlighters = {},

  -- Delays (in ms) defining asynchronous highlighting process
  delay = {
    -- How much to wait for update after every text change
    text_change = 200,

    -- How much to wait for update after window scroll
    scroll = 50,
  },

}
