Vimgo

Vimgo is a vim configuration that I used in daily coding. It is still in progress, but will become better and better.

Prerequisite

Vimgo uses vim-airline. For the nice looking powerline symbols to appear, you will need to install powerline fonts. Installation instructions can be found in this documentation.

Install

To install vimgo, simply do following in your terminal:

git clone https://github.com/pyericz/vimgo.git ~/.vimgo
cd ~/.vimgo && ./install.sh

Screenshots

Included Plugins

Start Screen

• Startify: Provides a start screen for Vim and Neovim.

File/Buffer Explorer

• vinegar: Combine with netrw to create a nice file system explorer. vinegar is my first choice to explore file system. You can toggle it on with -.
• NERDTree: In case you don't like vinegar, NERDTree is your second choice.
• BufExplorer: Easily switch between buffers. Can be opened with <leader+o>.
• MRU: Most recently used buffer. Can be opened with <leader+f>.

Fuzzy Finding

• CtrlP: Fuzzy file, buffer, mru and tag finder. Can be opened with <Ctrl+F>.
• fzf: Fzf wrapper for vim. Use <Ctrl-B> to open BTags, which is somewhat like Goto Symbol... feature using in Sumblime Text editor. If you had installed rg, with fzf you can search rg results with :Rg [PATTERN].

Lint

• ale: Syntax and lint checking for vim (async).

Git

• vim-fugitive: A Git wrapper so awesome.

Auto Completion

• coc.nvim: Intellisense engine for vim8 & neovim, full language server protocol support as VSCode.
• snippets: Snippets files for various programming languages.

Languages

• polyglot: A collection of language packs for Vim.

Status Line

• vim-airline: Lean & mean status/tabline for vim that's light as air.

Yank

• vim-yankstack: Maintains a history of previous yanks, changes and deletes

Misc

• commentary: Comment stuff out. Use gcc to comment out a line (takes a count), gc to comment out the target of a motion. gcu uncomments a set of adjacent commented lines.
• Multiple Cursors: Sublime Text style multiple selections.
• IndentLine: Display the indention levels with thin vertical lines.
• Auto Pairs: Insert or delete brackets, parens, quotes in pair.

Key Mappings

Basic

" With a map leader it's possible to do extra key combinations
" like <leader>w saves the current file
let mapleader = ","

" Smart way to move between windows
map <C-j> <C-W>j
map <C-k> <C-W>k
map <C-h> <C-W>h
map <C-l> <C-W>l

" Switch CWD to the directory of the open buffer
map <leader>cd :cd %:p:h<cr>:pwd<cr>

" Disable highlight when <leader><cr> is pressed
map <silent> <leader><cr> :noh<cr>

" Useful mappings for managing tabs
map <leader>tn :tabnew<cr>
map <leader>to :tabonly<cr>
map <leader>tc :tabclose<cr>
map <leader>tm :tabmove

" remove trailing space
map <leader>ts :%s/\s\+$//e<cr>:noh<cr>:w<cr>
