Over summer, I attended the Recurse Center. I noticed that around half the people in my batch were using Vim, and figured it would be a good time to try it out. I ran into two difficulties:
- I knew the basics of using Vim but I was less efficient than with my previous editor, Visual Studio Code
- I didn’t know how to configure Vim to use the syntax highlighting, indentation and linters I was used to. I was trying out lots of different programming languages, and needed to set Vim up for each one separately.
I decided to deal with these problems separately. I focused on the former by using a preconfigured Vim setup to defer having to think about the latter.
Initial Vim configuration
I installed Amir Salihefendic’s vimrc. It provided a really good starting point, and I’d recommend it to people who don’t want to roll their own config.
Once I felt productive at using Vim, I decided to write my own Vim configuration. This let me address some minor issues I had:
- I found it difficult to understand which features were and built into
Vim, and which came from the
vimrccontained features I didn’t use
vimrcvendored packages into the repo. To add new things, I needed to use git submodules, a lower level of abstraction than I wanted to use
- I forked the repo to make some changes. Maintaining the fork and keeping everything up to date was a lot of effort
Current Vim configuration
I wanted a configuration that was:
- Language agnostic and supported a wide range of languages
- Minimal and close to native Vim where possible
- Easy to edit and used a modern package manager
You can see my full configuration on GitHub. It’s just over 100 lines of code, including comments and newlines.
I use Tim Pope’s vim-vinegar to interact
with the filesystem and open files. It’s a thin wrapper around Vim’s built in
netrw. When editing a file, pressing
- opens a listing of that file’s parent
- again to moves you up a directory. To find a particular
directory or file, I use the normal Vim search (
I’ve heard good things about fuzzy finders such as fzf, but haven’t used them myself.
Splits and tabs
I use both tabs and splits to edit multiple files. At work I mostly code on a large number of microservices written in Go. I’ll use one tab per service, and two or three splits per tab.
To open splits, I’ve mapped
= to open the current file in a vertical split. I
use this in conjunction with
- command to quickly open files
from the same package/directory in a new split.
I don’t currently interact with the open buffer list directly.
To move between splits, I’ve added the mappings
" Easy split navigation map <C-j> <C-w>j map <C-k> <C-W>k map <C-h> <C-W>h map <C-l> <C-W>l
To create new tabs I use
T, and to switch between them, I use
" Simplify using tabs nnoremap ˙ gT nnoremap ¬ gt nnoremap T :tabnew<cr>
I use two plugins to get decent Vim support for most languages I’ll ever use:
Interacting with code
I use a couple of small plugins which make writing code marginally easier. The features they implement come built into Visual Studio Code:
- vim-commentary: Comment out lines or blocks of code. It works for most languages I’ve tried
- auto-pairs: When you type a left parenthesis, it automatically types a right parenthesis and moves your cursor between the two
- vim-gitgutter: Display a green
+or a red
-next to columns that have been edited in a file
:set colorcolumn = 80: Display a faint line at 80 chars
I use Junegunn Choi’s vim-plug as my
package manager. I like its simple API (add GitHub repos, run
operates at a higher level of abstraction than
Pathogen or Vim 8’s native package
loading in that you don’t interact with your plugins’ files directly. This feels
familiar if you’re used to brew/apt-get/pip etc.
