Navigator

Easy code navigation through LSP and 🌲Treesitter symbols, diagnostic errors.

Features:

• LSP easy setup. Support some of the most commonly used lsp client setup
• Unorthodox UI with floating windows
• fzy search with Lua-JIT
• Better navigation for diagnostic errors, Navigate through files that contain errors/warnings
• Group references/implementation/incomming/outgoing based on file names.
• Nerdfont, emoji for LSP and Treesitter kind

Why a new plugin

After installed a handful of lsp plugins, I still got ~800 loc for lsp and treesitter and still increasing because I need to tune the lsp plugins to fit my requirements. Navigator.lua help user setup lspconfig with only a few lines of codes. This plugin provide a visual way to manage and navigate through symobls, errors etc. It also the first plugin, IMO, that allows you to search in all treesitter symbols in the workspace.

Similar projects / special mentions:

• nvim-lsputils
• nvim-fzy
• fuzzy
• lspsaga
• fzf-lsp lsp with fzf as gui backend

Install

You can remove your lspconfig setup and use this plugin. The plugin depends on guihua.lua, which provides GUI and fzy support.

Plug 'ray-x/guihua.lua', {'do': 'cd lua/fzy && make' }
Plug 'ray-x/navigator.lua'

Packer

use {'ray-x/navigator.lua', requires = {'ray-x/guihua.lua', run = 'cd lua/fzy && make'}}

Setup

lua require'navigator'.setup()

Sample vimrc

call plug#begin('~/.vim/plugged')

Plug 'neovim/nvim-lspconfig'
Plug 'ray-x/guihua.lua', {'do': 'cd lua/fzy && make' }
Plug 'ray-x/navigator.lua'

call plug#end()

lua <<EOF
local nvim_lsp = require('lspconfig')
require'navigator'.setup()
EOF

Generally speaking, you could remove most part of your lspconfig.lua and use the hooks in navigator.lua

Depency

• lspconfig
• guihua (provides floating window, FZY)
• Optional:
  • lsp-status
  • lsp-signature
  • vim-illuminate

The plugin can be loaded lazily (packer opt = true ), And it will check if optional plugins existance and load those plugins only if they existed.

Usage

Please refer to lua/navigator/lspclient/mapping.lua on key mappings. Should be able to work out-of-box.

• Use <c-e> or :q! to kill the floating window
• <up/down> (or <c-n>, <c-p>) to move
• <c-o> to open location or apply code actions

Todo

• Early phase, bugs expected, PR and suggestions are welcome
• Async (some of the requests is slow on large codebases and might be good to use co-rountine)
• More clients. I use go, python, js/ts, java, c/cpp, lua most of the time. Do not test other languages (e.g dart, swift etc)
• Configuration options
