Included Plugins

I recommend reading the docs of these plugins to understand them better. Each plugin provides a much better Neovim experience!

• ack.vim: Vim plugin for the_silver_searcher (ag) or ack -- a wicked fast grep
• bufexplorer.zip: Quickly and easily switch between buffers. This plugin can be opened with <leader+o>
• ctrlp.vim: Fuzzy file, buffer, mru and tag finder. It's mapped to <Ctrl+F>
• goyo.vim:
• lightline.vim: A light and configurable statusline/tabline for Vim
• NERD Tree: A tree explorer plugin for vim
• mru.vim: Plugin to manage Most Recently Used (MRU) files. This plugin can be opened with <leader+f>
• open_file_under_cursor.vim: Open file under cursor when pressing gf
• snipmate.vim: snipmate.vim aims to be a concise vim script that implements some of TextMate's snippets features in Vim
• ale: Syntax and lint checking for vim (ALE requires NeoVim >= 0.2.0 or Vim 8 with +timers +job +channel)
• vim-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.
• vim-expand-region: Allows you to visually select increasingly larger regions of text using the same key combination
• vim-fugitive: A Git wrapper so awesome, it should be illegal
• vim-indent-object: Defines a new text object representing lines of code at the same indent level. Useful for python/vim scripts

Included color schemes

• onedark The default
• vim-one
• iceberg
• gruvbox
• Oceanic Next
• Deep Space

Key Mappings

The leader is ,, so whenever you see <leader> it means ,.

Normal mode mappings

Fast saving of a buffer (<leader>w):

nmap <leader>w :w!<cr>

Map <Space> to / (search) and <Ctrl>+<Space> to ? (backwards search): map / map ? map :noh

Disable highlights when you press <leader><cr>: map :noh

Smart way to move between windows (<ctrl>j etc.): map j map k map h map l

Closing of the current buffer(s) (<leader>bd and (<leader>ba)): " Close current buffer map bd :Bclose

" Close all buffers
map <leader>ba :1,1000 bd!<cr>

Useful mappings for managing tabs: map tn :tabnew map to :tabonly map tc :tabclose map tm :tabmove

" Opens a new tab with the current buffer's path
" Super useful when editing files in the same directory
map <leader>te :tabedit <C-r>=expand("%:p:h")<cr>/

Switch CWD to the directory of the open buffer: map cd :cd %:p:h:pwd

Open ack.vim for fast search: map g :Ack

Quickly open a buffer for scripbble: map q :e ~/buffer

Toggle paste mode on and off: map pp :setlocal paste!

Visual mode mappings

Visual mode pressing * or # searches for the current selection:

vnoremap <silent> * :call VisualSelection('f')<CR>
vnoremap <silent> # :call VisualSelection('b')<CR>

When you press gv you Ack.vim after the selected text:

vnoremap <silent> gv :call VisualSelection('gv', '')<CR>

When you press <leader>r you can search and replace the selected text:

vnoremap <silent> <leader>r :call VisualSelection('replace')<CR>

Surround the visual selection in parenthesis/brackets/etc.:

vnoremap $1 <esc>`>a)<esc>`<i(<esc>
vnoremap $2 <esc>`>a]<esc>`<i[<esc>
vnoremap $3 <esc>`>a}<esc>`<i{<esc>
vnoremap $$ <esc>`>a"<esc>`<i"<esc>
vnoremap $q <esc>`>a'<esc>`<i'<esc>
vnoremap $e <esc>`>a"<esc>`<i"<esc>

Insert mode mappings

Quickly insert parenthesis/brackets/etc.:

inoremap $1 ()<esc>i
inoremap $2 []<esc>i
inoremap $3 {}<esc>i
inoremap $4 {<esc>o}<esc>O
inoremap $q ''<esc>i
inoremap $e ""<esc>i
inoremap $t <><esc>i

Insert the current date and time (useful for timestamps):

iab xdate <C-r>=strftime("%d/%m/%y %H:%M:%S")<cr>

Command line mappings

$q is super useful when browsing on the command line. It deletes everything until the last slash:

cno $q <C-\>eDeleteTillSlash()<cr>

Bash like keys for the command line:

cnoremap <C-A>		<Home>
cnoremap <C-E>		<End>
cnoremap <C-K>		<C-U>

cnoremap <C-P> <Up>
cnoremap <C-N> <Down>

Write the file as sudo (works only on Unix). Super useful when you open a file and you don't have permissions to save your changes. Vim tip:

:W 

Plugin related mappings

Open bufexplorer to see and manage the current buffers (<leader>o): map o :BufExplorer

Open MRU.vim to see the recently open files (<leader>f):

map <leader>f :MRU<CR>

Open ctrlp.vim plugin to quickly find a file or a buffer (<leader>j or <ctrl>f): let g:ctrlp_map = ''

NERD Tree mappings:

map <leader>nn :NERDTreeToggle<cr>
map <leader>nb :NERDTreeFromBookmark 
map <leader>nf :NERDTreeFind<cr>

ctrl-p mappings to easily find and open a file, buffer, etc.:

let g:ctrlp_map = '<C-f>'
map <leader>j :CtrlP<cr>
map <C-b> :CtrlPBuffer<cr>

vim-snipmate mappings to autocomplete via snippets:

ino <C-j> <C-r>=snipMate#TriggerSnippet()<cr>
snor <C-j> <esc>i<right><C-r>=snipMate#TriggerSnippet()<cr>

vim-surround mappings to easily surround a string with _() gettext annotation:

vmap Si S(i_<esc>f)
au FileType mako vmap Si S"i${ _(<esc>2f"a) }<esc>

ale to easily go to the next Ale syntax/lint error:

nmap <silent> <leader>a <Plug>(ale_next_wrap)

Spell checking

Pressing <leader>ss will toggle spell checking:

map <leader>ss :setlocal spell!<cr>

Shortcuts using <leader> instead of special characters:

map <leader>sn ]s
map <leader>sp [s
map <leader>sa zg
map <leader>s? z=

Cope

Query :help cope if you are unsure what cope is. It's super useful!

When you search with Ack.vim, display your results in cope by doing: <leader>cc

To go to the next search result do: <leader>n

To go to the previous search results do: <leader>p

Cope mappings:

map <leader>cc :botright cope<cr>
map <leader>co ggVGy:tabnew<cr>:set syntax=qf<cr>pgg
map <leader>n :cn<cr>
map <leader>p :cp<cr>
