👁️ bufignore

Bufignore is a plugin for Neovim that helps you keep your buffer list organized by automatically unlisting hidden buffers that match specific ignore sources, such as a Lua pattern or Git ignored files. It was designed to solve the annoyance of a cluttered buffer list when working with Git ignored files, such as those within .git or node_modules.

✨ Key features

• Multiple ignore sources: You can define multiple ignore sources, such as Lua patterns and Git ignored files, to filter out hidden buffers that match these patterns.
• Tidy buffer list: It unlists hidden buffers that match the defined ignore sources to keep your buffer list tidy.
• Efficient event processing: The plugin efficiently utilizes a queue for all events, which feeds batches of buffer events into processing.
• Supports changing working directory: Bufignore supports changing the current working directory by testing all current buffers, and only unlists files that are ignored and within the current working directory.
• Out-of-the-box usage: Bufignore works out-of-the-box without requiring any configuration tweaking.
• Customizable: Bufignore provides a callback function that allows you to further configure which buffers should be unlisted based on your needs.
• Ignores files outside the current working directory: Bufignore only considers files within the current working directory, ignoring files outside it.

⚡ Requirements

• Neovim, with the hidden option set to on.
• Git.
• plenary.nvim.

📦 Installation

lazy

{
  'sQVe/bufignore.nvim',
  dependencies = { 'nvim-lua/plenary.nvim' },
  opts = {
    -- Input configuration here.
    -- Refer to the configuration section below for options.
  }
},

packer

use({
  'sQVe/bufignore.nvim',
  requires = { 'nvim-lua/plenary.nvim' },
  config = function()
    require("bufignore").setup({
      -- Input configuration here.
      -- Refer to the configuration section below for options.
    })
  end
})

⚙ Configuration

The following code block shows the available options and their defaults:

{
  auto_start = true,
  ignore_sources = {
    git = true,
    patterns = { '/%.git/' },
    symlink = true,
    ignore_cwd_only = true,
  },
  pre_unlist = nil,
}

auto_start

A boolean value that determines whether to start the plugin automatically after calling setup().

ignore_sources

A table that sets which sources to use when checking whether a file is supposed to be unlisted or not.

git

A boolean value that determines whether Git ignored files are unlisted or not.

patterns

A table of Lua patterns that determines whether the file should be unlisted or not.

symlink

A boolean value that determines whether symlinked files are unlisted or not.

ignore_cwd_only

A boolean value that determines whether to only unlist files that are within the current working directory.

pre_unlist

A callback function that executes before unlisting a buffer. You can use this function to customize which buffers to unlist by returning a boolean value. The unlisting process will only proceed if the callback function returns true.

Parameters

• event ({ bufnr: number, file_path: string }) - A table with buffer information.

Return

Return true to proceed with the unlisting process, or anything else to prevent the buffer from being unlisted.

📗 Usage

Bufignore works out-of-the-box with the auto_start option enabled. The following API is available under require('bufignore') if you want to handle things manually:

  • Avoid processing duplicate file paths.
• Support for extending ignore lookup beyond Git.
  • Lua patterns.
  • Symlinks.
  • Filetypes.
  • Outside the Git repository.
  • Outside the current working directory.
  • Custom callback.
