Vim cfg

Personal Vim configuration focused on C/C++ development, code navigation, and fast project search.

Keymap

Quick reference: KEYMAP.md

Features

• LSP workflow via coc.nvim + clangd
• Fast file/symbol search via LeaderF (+ ripgrep)
• Git blame integration via vim-fugitive
• Project tree via NERDTree
• Async build task via asyncrun.vim
• ctags/cscope based code navigation

Requirements

Required

• Vim 8.2+ (newer is better for coc.nvim)
• nodejs (for coc.nvim)
• clangd
• universal-ctags

Install base dependencies (Ubuntu example):

sudo apt install nodejs clangd universal-ctags

Optional but recommended

• ripgrep (used by LeaderF grep search)
• cscope (for cs find)

sudo apt install ripgrep cscope

Installation

1. Clone this repo to ~/.vim.
2. Run:

bash install.sh

install.sh will:

• download vim-plug (autoload/plug.vim) if missing
• back up existing ~/.vimrc and ~/.vim to ~/.vimrc_bak / ~/.vim_bak
• create symlinks to this repo (~/.vim, ~/.vimrc)

Plugin setup

Open Vim and run:

:PlugInstall
:CocInstall coc-clangd

Optional index setup (project root)

ctags -R
cscope -Rb
