Vim beginner's customization guide

This article is for those who've been using Vim for a little while and have started to grasp modal editing and the powers of Vim, and now want to start customizing it. If you're completely new to Vim, I have another post describing some of the basic of learning Vim here but there are dozens of them on the internet, and Vim ships with vimtutor as well which is a great place to start.

I'm going to try to walk you through the process of creating your own configuration, by giving you my biased opinions in attempt to save you from some of the boring bits of testing things out (which admittedly can also be a rewarding process).

This is written under the assumption you're running a Linux distro, but much of this will work on Mac, and some of it on Windows too. Your mileage may vary.

Initial configuration

At this point I'm assuming you have no ~/.vim directory and no ~/.vimrc file. Let's make a directory skeleton to use in your vimrc later with this command:

mkdir -vp ~/.vim/{autoload,bundle,cache,undo,backups,swaps}

Then, let's install a plugin manager called vim-plug with this command:

curl -fLo ~/.vim/autoload/plug.vim

(Aside: There are definitely many choices of plugin managers, but to me, vim-plug is the best of them; the syntax is very clean and it does parallel processing which makes updates so much faster than others. The other biggest contender would be NeoBundle which offers more fine-grained control, but I find the extra control is rarely needed, and vim-plug will do just about all of that anyway and with cleaner syntax. There's also Vundle but it doesn't have delayed loading of plugins which is a really great feature not to be missed out on.)

Now, open your ~/.vimrc with Vim, and let's use Vim-plug to install a minimal, sensible, set of default options by adding the following lines:

call plug#begin('~/.vim/bundle')
Plug 'tpope/vim-sensible'
call plug#end()

There's an extra plugin there called vimproc that you'll want to let Vim do things asynchronously. The second half of that tells Vim-plug to run the command make whenever it's installed or updated.

Now let's save this file and install the plugin with this command: :w | so % | PlugInstall. You're hopefully familiar with :ex commands like :w, :q, and :s but you may not be aware you can chain them together with |. This is equivalent to running :w, then :so % which is a shortcut for :source <current filename>, and then running :PlugInstall. At this point I would recommend taking a look at the options Vim-sensible defines.

As you're working/reading through this article, try to add comments to help you remember what things do later on (comments are started with " but I prefer to use two of them). If you find yourself wondering what a setting does, put your cursor on the word and run :help <C-r><C-w> (where <C-r><C-w> means Ctrl+r then Ctrl+w).

More sensible configurations

Vim's default nature when handling buffers is to not allow opening a new one or changing to a new buffer without saving change to the current one. Anyone who's spent any time in another editor will likely find this incredibly annoying (at least I do), and want Vim to just remember their changes for the moment and focus on a new buffer without prompting to save first. This line will do that:

set hidden

I might have said this earlier, but any options you add to your vimrc are not read by the current instance, unless you run :source ~/.vimrc. You can write an autocmd to do this automatically whenever you save, but if you make a typo and save it, you're gonna have a bad time. See the bottom if you want this functionality. This is probably a good time to let you know that if you do make a typo and your config file for some reason stops you from using Vim properly, you can tell Vim to start in 'safe mode' with vim -u NONE (I tend to add the -N switch also to make Vim force nocompatible mode).

I quite like having line numbers in a text editor, and in recent versions there's also relative line numbering which is great to have in Vim, since you're most often moving around relative to your position rather than to an absolute line (which, of course, can still be done). The following lines will add line numbers and relative line numbers (or not if you're using a version that doesn't support it):

set number
if exists('+rnu') | set relativenumber | endif

If you prefer, you can split that into multiple lines where the | bars are.

I'm going to suggest yet plugin (did I mention this article will be filled with lots of them?) from Tim Pope called unimpaired that adds a bunch of keybinds that, I think, should be added by default.

Plug 'tpope/vim-unimpaired'

With this plugin you can now toggle line numbers with con and relative numbers with cor. My most used features of this plugin are changing buffers with [b and ]b and pasting with yo/yO. You should read the list of all these key-binds by running :vert help unimpaired. I cannot stress the importance of this: you should really, really, read the help file of every plugin you add to your vimrc. You can get a list of all help files for your plugins by running :help local-additions.

tpope has another great plugin that I use a lot that proves Vim commands for some common UNIX commands. As an example, I often decide I want to rename or move a file in the middle of working on it, and while :saveas almost does the trick, it still leaves the original file on disk, and (Eunuch)[] provides a :Move command to solve this problem. As another example, I sometimes start editing a file, and find that I need root privileges to write to it, and this plugin provides :SudoWrite.

Plug 'tpope/vim-eunuch'

Another one of tpope's great plugins is surround. This "provides mappings to easily delete, change and add such surroundings in pairs." The README and help file does a great job of explaining how to use it so I won't bother with that here.

Plug 'tpope/vim-surround'

Before I forget, and while I'm still talking about tpope, there's yet another plugin he's written that expands on the power of the . command which repeats the last action. . doesn't always work with plugins, so this plugin attempts to fix that.

Plug 'tpope/vim-repeat'

Vim has a very powerful undo tree, which is different from the linear undo lists most editors use. Having this tree be persistent even after quitting is one of my favorite features of Vim, and so is having your :ex command history be persistent. The following lines will accomplish this:

if version >= 703
if exists("&undodir")
set undodir=~/.vim/undo//
set undofile
set undoreload=10000
set undolevels=10000
if exists("&backupdir")
set backupdir=~/.vim/backups//
if exists("&directory")
set directory=~/.vim/swaps//

There's also a plugin called gundo that I recommend adding to graphically navigate the undo tree. Vim-plug also has the ability to not load this plugin until you actually use it, although most of the time this isn't necessary because Vim natively has on-demand loading of plugins if they're written correctly.

Plug 'sjl/gundo.vim', {'on': 'GundoToggle'}

If you want to bind opening this to a key, you can do that with

nnoremap <silent> <F5> <Esc>:GundoToggle<CR>

But you can, of course, replace <F5> with something else like <leader>u if you prefer. Make sure to read the help file for Gundo, there's several settings in there you can tweak.

This is probably a good time to explain mappings and why I chose that particular string of characters. map is the most primitive way in Vim to make a key map to a certain command or function, but map is recursive and this is usually an undesired effect, so noremap, as in "non-recursive" map is usually used. nnoremap (notice the extra n at the beginning) is a non-recursive map in normal mode. I used <silent> here because I don't prefer to have the command print in the command prompt. I add the <Esc> to make sure the :ex command is entered exactly as intended and there weren't any previously entered characters like numbers added that might cause undesired effects. The <CR> at the end is short for 'carriage return', which is how you tell Vim to push enter and actually execute the command.

Vim-sensible enables incsearch which highlights the first match as you type, which is great and all, but there's a pretty awesome plugin that expands on this power to not just highlight the first match, but all visible matches on the screen, which is extremely handy for writing regex. (Again, make sure to check the help file!)

A note on organization: Your vimrc can quickly become a jumbled mess if you're not careful, so I find it helps to group things into folds. For instance, in my vimrc, I use several settings for this plugin, so directly underneath the plugin definition I add the settings and then wrap the whole block in a fold. This lets me use zc to close the fold (which hides the contents), and then zo to open it (or zm/zr to increase/decrease the foldlevel). The entire block looks like so:

Plug 'haya14busa/incsearch.vim' " {{{
map / <Plug>(incsearch-forward)
map ? <Plug>(incsearch-backward)
map g/ <Plug>(incsearch-stay)
map n <Plug>(incsearch-nohl-n)
map N <Plug>(incsearch-nohl-N)
map * <Plug>(incsearch-nohl-*)
map # <Plug>(incsearch-nohl-#)
map g* <Plug>(incsearch-nohl-g*)
map g# <Plug>(incsearch-nohl-g#)
let g:incsearch#consistent_n_direction = 1
let g:incsearch#auto_nohlsearch = 1
let g:incsearch#magic = '\v'
" }}}

I also use incsearch in conjunction with vim-over for live preview of substitutions:

Plug 'osyo-manga/vim-over' " {{{
let g:over_command_line_prompt = ":"
let g:over_enable_cmd_window = 1
let g:over#command_line#search#enable_incsearch = 1
let g:over#command_line#search#enable_move_cursor = 1
nnoremap <silent> <Leader>s <Esc>:OverCommandLine %s///g<CR><Left><Left>
xnoremap <silent> <Leader>s <Esc>:OverCommandLine '<,'>s///g<CR><Left><Left>
" }}}

One of my new favorite plugins is vim-sneak and I can't believe how long I went without it. This overrides the s command (which has the same effect as xi or cl) to provide a motion that lets you jump to the next two characters you give it. If you've seen EasyMotion (which I strongly dislike), it's similar to that but faster and more lightweight, and actually provides a motion for use with operators (instead of just moving your cursor). It can also extend f F t T ; , to work across multiple lines which is killer. Be sure to read the :help file for it (have I said this enough yet?), there's some settings you'll definitely want to play with.

The settings I use for this are:

Plug 'justinmk/vim-sneak' " {{{
let g:sneak#prompt = '(sneak)» '
map <silent> f <Plug>Sneak_f
map <silent> F <Plug>Sneak_F
map <silent> t <Plug>Sneak_t
map <silent> T <Plug>Sneak_T
map <silent> ; <Plug>SneakNext
map <silent> , <Plug>SneakPrevious
" }}}

targets.vim is a very cool plugin that provides some extra modifiers and text-objects to operate on. Vim-surround adds the surround text-object, and while Vim provides you with ci) to "change inside parenthesis", this really only works if your cursor is inside the parenthesis. Targets provides (among many other things) modifiers like cin) to "change inside next parenthesis". You'll have to read the help file for all of the features it provides.

Since text-objects are arguably Vim's most compelling feature, why not take advantage of the ability to create our own? kana/vim-textobj-user/wiki has a list of dozens of custom text-objects you can install, and of course the engine gives you the ability to create your own.

Fancy suggestions

Determining whether a file is using tabs or spaces consistently isn't easily done, but Vim has a few features for handling non-visible chars. You'll want to check the help files for more information.

set list listchars=tab:\›\ ,trail:★,extends:»,precedes:«,nbsp:•
"" set listchars+=eol:↵ "" uncomment this line if you want to show end of line chars
set fillchars=stl:\ ,stlnc:\ ,vert:│,fold:\ ,diff:-

As far as looks go in Vim, compared to more modern editors, it's not exactly the nicest to look at. There are a dozens plugins that attempt to spice up Vim's interface, I have found Airline very attractive to look at and very functional while not being too heavy on resources. On top of having a nice statusline at the bottom telling you which mode you're in (and changing colors accordingly), it will also list all of your open buffers or tabs in the tabline.

If that's too fancy for you, you can play with the ruler, which by default only shows the current line number and column, but you can put many things in the ruler:

set rulerformat=%30(%=\:b%n%y%m%r%w\ %l,%c%V\ %P%)

If you want to learn how all the syntax works, check out :h statusline.

Programming specific plugins

If you're like me and you spend a lot of time using Vim to write code you'll probably want to make it behave a bit like an IDE, and get some syntax checking and/or code completion added to Vim.

If you want syntax linting, you can try Syntastic if you're stuck with an older version of Vim, but if you're using Vim 8 (or NeoVim) you should use look into ALE. The biggest selling point of ALE is that it shows errors while you're typing without making the editor hang (which is a problem with Syntastic which can grind the editor to a halt after a saving a file). NeoMake is another choice but I can't think of any reason to use it over ALE.

Next, I recommend using snippets. Snippets are shortcuts allow you to, for instance, type for<C-k> and have Vim move your cursor around while you fill in the blanks. There are two major choices: UltiSnips and NeoSnippet. Honestly I never tried UltiSnips, mostly because NeoSnippet ties in nicely together with the completion engine I use. Keep in mind both of those are just the engine, there are separate plugins for the actual libraries. As always, check the README.

When it comes to code-completion, while Vim's built-in completion is pretty great, it does leave something to be desired if you're looking for something that intelligently parses your code. There are at least half a dozen choices, and some of them have drawbacks compared to others, so you'll really want to spend a little time playing with each and see which you prefer most. I've narrowed it down to two:

  • YouCompleteMe - Perhaps the most popular, this is really good at completion for C-languages and also works for Python and has support for a few other languages. It's pretty kind of complicated to install and depends on clang.
  • NeoComplete - This is the one I use, mostly because I don't work with C-languages and it seems to function how I'd expect, but it depends on Vim's Lua support (which you can test by looking for +lua in vim --version). NeoComplCache is similar but doesn't have the same dependencies nor quite the same feature set. There's a newer version of NeoComplete called Deoplete that Shougo is working on for NeoVim and the new async features of Vim 8; as of this writing it's not 100% finished, but it's worth trying.

It's also possible to use YouCompleteMe if clang is available, or attempt NeoComplete if it can, and fall-back to NeoComplCache if all else fails, so I wrote a gist for this idea (though I never actually tested it, so let me know how it works if you try it).

If you do web development then you'll most definitely want emmett.vim which is more of a text expander: it lets you write CSS-style selections and then expands them in to the markup it requires. For example ul>li*2 expands to <ul><li></li><li></li></ul> (but with linebreaks and indention). Emmet is completely life-changing for writing HTML/XML/JSX. Here's a cheat-sheet to help you get started with some of the expansions it provides.

A few more goodies for you:

  • delimitMate - this will add matching parenthesis, quotes, braces, brackets as soon as you type the first one. I cry whenever I use Vim and this isn't available.
  • endwise - provides a few closing lines for things like if, for, function, etc in several languages
  • commentary - provides a gc verb for commenting lines with motions or selections
  • fugitive - another one of tpope's great contributions, it may very well be the best Git wrapper of all time
  • git-gutter - a handy companion to fugitive that shows diff signs from the current commit beside line numbers
  • gist - speaking of Git, it's often really handy to send a file or just a selection of a file to gist to share with people. This plugin does that very nicely
  • filebeagle - if you've come from IDE-land you may be tempted to try and find some sort of file browser for Vim. NERDtree is one of the more popular choices for this, but it uses splits which can be disruptive to your other splits, and personally just does too much. I've been using filebeagle which does two things: lists and opens files.

Prose plugins

If you're into writing prose there are a few plugins I've found that help with this:

  • vim-pencil - provides commands for changing word wrap settings between hard and soft style
  • vim-lexical - improves spell-check and adds thesaurus completions
  • vim-textobj-sentence - improves the built-in sentence text-object with recognition for common abbreviations and quotations
  • vim-wordy - highlights problematic phrases and words

Even more plugins

A popular choice for many users is CtrlP, which lets you fuzzy filter through files, buffer, tags, etc. It's pretty simple to configure and many users love it.

Another choice for filtering through lists is FZF. FZF isn't actually a Vim plugin (although Junegunn has made an extension for it), but a generic fuzzy filter program, that reads stdin and prints selections to stdout, so it can be used with any program. I've written probably half a dozen scripts with FZF and it's a great program, but the biggest catch is that for it to work cleanly in Vim you need to run Vim inside tmux so it can create a tmux split below Vim. If you use FZF without tmux or inside GVim, FZF will spawn an external terminal to show the filter list. Although, if you use NeoVim, this isn't an issue since it implements it's own terminal emulator, and can run FZF directly in a Vim split.

Unite.vim, is a bit more ambitious, and I think it takes a bit of inspiration from Emacs' helm. Unite is very extensible, it comes with a dozen sources (which is 'Unite speak' for inputs like the buffer list, yank history, register contents, etc) out of the box, and there are probably hundreds more you can install (there are plugins for this plugin). It doesn't come with any default mappings, you will have to define your own, and it will take some time configuring (and possibly/probably a bit of head scratching), but it is a very powerful plugin.
Arguably the best feature about Unite is that you can combine 'sources' to filter through. For example, I have <leader>f bound to show files in the current working directory (and I can navigate through folders by typing through paths), most recently used files, any file that might match what's under the cursor (similar to the gf command), or if nothing else matches, create a new file. It can be configured to show as a split below, above, or to the side of the current buffer, or can use the entirety of the current buffer (similar to the netrw interface, but with the whole interactive filter bit), and you can define certain commands to split and behave differently than others.

I've never used Sublime Text, but I found a plugin that tries to implement it's multiple cursors feature, which is useful for all kinds of things, especially variable renaming.

If you use tmux you might want some integration with it and REPLs in other panes. There are lots of these plugins that do things slightly differently so you should try a few and find one that does what you like. I use tmuxify because it was the first I found that worked how I expected.

Personal tweaks

If you have a lot of <leader> key mappings, you'll probably find that the default \ key can be a bit hard to reach. Well, the space bar doesn't really do much besides advance the cursor one char, just like l does, so I think it's a great candidate for being mapleader since it's so easily accessible.

let g:mapleader = "\<Space>"

The default behavior of Y is to yank the entire line (which can be done with yy), but I like Y to behave more like C and D, which work from the cursor to the end of the line.

nnoremap Y y$

When searching with n and N I often find it difficult to see exactly where the next search was, so I use zt to put that line at the top of the scrolling area (or zz to center the line). Sometimes the search is inside a fold that I have to open with zv to see it. At some point I realized I do this so often that I should really just make it my default behavior:

nnoremap n nzvzt
nnoremap N Nzvzt

note that if you're using the incsearch plugin to handle all of your searching you'll have to add the zvzt to the end of that plug mapping

If you've used Vim with wrapped text, you may have noticed that j and k don't quite behave as expected, as they jump literal lines and not visible lines, which is done with gj and gk. I thought it would be handy to have a function to swap them around as needed, so here it is:

function! Togglegjgk()
if !exists("g:togglegjgk") || g:togglegjgk==0
let g:togglegjgk=1
nnoremap j gj
nnoremap k gk
nnoremap gk k
nnoremap gj j
echo 'j/k swapped with gj/gk'
let g:togglegjgk=0
nunmap j
nunmap k
nunmap gk
nunmap gj
echo 'normal j/k'
nnoremap <silent> <leader>tgj <Esc>:call Togglegjgk()<CR>

Early in the text I mentioned autocmd, which is a very powerful feature in Vim. They do have some caveats to be aware of, and the syntax is slightly strange at first, so check out :h autocmd. Any time your vimrc is re-sourced Vim will re-add your autocmds to it's list, so it's good to wrap them in either an augroup to clear them, or a condition to not re-load them (I opt for the former). Here's a quick sample of how to :source your vimrc whenever it's saved, and, if you're using Airline, fix a strange quirk it has when re-sourcing:

augroup VIM
autocmd BufWritePost ~/.vimrc
\ source ~/.vimrc |
\ if exists(':AirlineRefresh') |
\ AirlineRefresh |
\ endif
augroup END

Because help files are so helpful in Vim, I find myself reading them a lot (and hopefully you have been too), but by default most of the help splits are horizontal (which makes no sense to me), so I have a couple autocmds for dealing with them. The first is to try and make all help splits vertical on the far right side and resized to 80 columns, and the other uses the :help <C-r><C-w> trick we used earlier and binds it to K, which by default runs man on the word your cursor is in. Again, this would go inside the augroup above:

autocmd FileType help
\ wincmd L |
\ vert resize 80
autocmd FileType Vim
\ nnore <silent><buffer> K <Esc>:help <C-R><C-W><CR>

You can also use an autocmd to load your last known cursor position whenever a file is read. Put this inside the block above.

autocmd BufReadPost *
\ if line("'\"") > 0 && line("'\"") <= line("$") |
\ exe 'normal! g`"zvzz' |
\ endif

If you want your Vim config to be more portable, it's possible to use your .vimrc to recreate your whole ~/.vim directory. This block will create missing directories and install Vim-Plug and the rest of your missing plugins: (works best at the top of the file)

let s:configdir = '~/.vim'
if has('nvim')
let s:configdir = '~/.config/nvim'
if empty(glob(s:configdir . '/bundle')) || empty(glob(s:configdir . '/autoload/plug.vim'))
augroup InstallPlugins
autocmd VimEnter * call s:InstallPlugins()
augroup END
function! s:InstallPlugins() abort
echo 'Install missing plugins? [y/N] '
let l:char = nr2char(getchar())
if l:char ==? 'y'
silent call system('mkdir -p ' . s:configdir . '/{autoload,bundle,cache,undo,backups,swaps}')
silent call system('curl -fLo ' . s:configdir . '/autoload/plug.vim')
execute 'source ' . s:configdir . '/autoload/plug.vim'
endif redraw!

Closing windows can be done a few different ways in Vim. :q will close the window and exit Vim if it's the only window open, :bd will delete the current buffer from memory but it will leave the window showing. <C-w>q will close the window but it won't remove the buffer, and that's without bringing tabs into it. That's a lot of thinking for a simple task, and keystroke or two more than I care for. Sayonara is a plugin that attempts to simplify this process with two commands: :Sayonara which removes the buffer and closes the window, and :Sayonara! (with the exclamation!) which removes the buffer but preserves the window. That's a lot more typing, so it needs a key-binding. The Q key starts you in :ex mode which is more often used on accident, and you can still get to this by typing gQ in normal mode, so I wrote this little function to override it and close buffers by typing QY, Qy, or Qc:

function! PromptQuit()
echo 'Y - kill buffer and current window'
echo 'y - kill buffer but preserve window'
echo 'c - kill window but preserve buffer'
echo 'close current buffer? '
let char = nr2char(getchar())
if char ==# 'Y'
elseif char ==# 'y'
execute 'Sayonara!'
elseif char ==? 'c'
wincmd q
silent! redraw!
nnoremap <silent> Q <Esc>:call PromptQuit()<CR>

Keep in mind that closing the last only window will also close Vim.

My last suggestion, which is not a tweak for Vim per-se, but is extremely beneficial for Vim users, is to swap your caps-lock and escape keys around. I mean, who actually makes consistent use of caps lock to want it on the home row within pinky's reach? That space would be much better suited for the escape key, and is actually how Bill Joy, the original author of vi expected the keyboard layout to be. On Linux you can do this with a single command:

setxkbmap -option 'caps:swapescape'

You may even want to look into xcape, which can make your caps-lock key function as escape when pressed by itself, or act as control when used as a modifier with another key.


this is still a work in progress
