nvim-lspfuzzy

This plugin makes the Neovim LSP client use FZF to display results and navigate the code. It works by redefining your LSP handlers so that they call FZF.

The plugin requires Neovim 0.6+. For Neovim 0.5, use version v0.1.0.

demo

Installation

With packer.nvim:

use {
  'ojroques/nvim-lspfuzzy',
  requires = {
    {'junegunn/fzf'},
    {'junegunn/fzf.vim'},  -- to enable preview (optional)
  },
}

With paq-nvim:

paq {'junegunn/fzf'}
paq {'junegunn/fzf.vim'}  -- to enable preview (optional)
paq {'ojroques/nvim-lspfuzzy'}

Usage

Simply add this line to your init.lua:

require('lspfuzzy').setup {}

If you're using a .vimrc or init.vim:

lua require('lspfuzzy').setup {}

In addition, the plugin creates the following commands:

  • :LspDiagnostics <bufnr>: list diagnostics from given buffer (use 0 for current buffer).
  • :LspDiagnosticsAll: list diagnostics from all buffers.
  • :LspFuzzyLast: re-open the last results (requires save_last = true, see Configuration).

By default the following FZF actions are available:

  • tab : select multiple entries
  • shift+tab : deselect an entry
  • ctrl-a : select all entries
  • ctrl-d : deselect all entries
  • ctrl-t : go to location in a new tab
  • ctrl-v : go to location in a vertical split
  • ctrl-x : go to location in a horizontal split

Configuration

You can pass options to the setup() function. Here are all available options with their default settings:

require('lspfuzzy').setup {
  methods = 'all',         -- either 'all' or a list of LSP methods (see below)
  jump_one = true,         -- jump immediately if there is only one location
  save_last = false,       -- save last location results for the :LspFuzzyLast command
  callback = nil,          -- callback called after jumping to a location
  fzf_preview = {          -- arguments to the FZF '--preview-window' option
    'right:+{2}-/2'          -- preview on the right and centered on entry
  },
  fzf_action = {               -- FZF actions
    ['ctrl-t'] = 'tab split',  -- go to location in a new tab
    ['ctrl-v'] = 'vsplit',     -- go to location in a vertical split
    ['ctrl-x'] = 'split',      -- go to location in a horizontal split
  },
  fzf_modifier = ':~:.',   -- format FZF entries, see |filename-modifiers|
  fzf_trim = true,         -- trim FZF entries
}

The fzf_preview and fzf_action settings are determined as follows:

  1. Values passed to setup() are used first.
  2. Otherwise the plugin will try to load values from the respective FZF options g:fzf_preview_window and g:fzf_action if they are set.
  3. Finally the default values will be used.

For others FZF options such as g:fzf_layout or g:fzf_colors the plugin will respect your settings.

Supported LSP methods

You can enable FZF only for some LSP methods by passing them as a list to the methods option when calling setup(). The supported LSP methods are:

callHierarchy/incomingCalls
callHierarchy/outgoingCalls
textDocument/declaration
textDocument/definition
textDocument/documentSymbol
textDocument/implementation
textDocument/references
textDocument/typeDefinition
workspace/symbol

Troubleshooting

Preview does not work

You need to install fzf.vim to enable previews. If it's already installed, make sure it's up-to-date.

Preview does not scroll to the selected location

Try to append +{2}-/2 to either g:fzf_preview_window or to the fzf_preview option in setup() to make the preview respect line numbers. For instance:

vim.g.fzf_preview_window = {'down:+{2}-/2'}

Using the fzf_modifier option breaks the plugin

The plugin uses the filename embedded in the FZF entry currently selected to jump to the correct location. Therefore it must resolve to a valid path: for instance :. or :p can be used but not :t.
