CLIfe or my development setup – Hacker Noon

Like many other people, I’ve started my programming journey by using big, powerful, clunky IDEs. I’ve used Borland Delphi, MS VS, Netbeans, Eclipse, IntelliJ IDEA, etc. As the time passed, and I slipped more into the web development, I switched to lighter options. For a while, my editor of choice has been Sublime Text. About three years ago, I’ve completely migrated to Vim, Tmux, and other non-GUI tools, and I’m totally in love with them so far!

Two things triggered the migration. First, at my new job, we all had laptops for working remotely, but most of the development was happening on the powerful stationary workstation located in the office. Using SSHFS or VNC over a shaky internet connection was a pain in the butt, so I needed a better option. Second, I was doing more and more of a DevOps kind of work, which required me editing files on dozens of remote machines every day, and Vi was the only editor available everywhere. Switching to Vim solved both problems for me, and after I discovered the ergonomics, and the plugin ecosystem, I completely ditched Sublime as my primary editor. Recently I noticed that more and more people are asking about my setup whenever they see my screen, so I decided to share it in a blog post.

Installing Neovim

Neovim is an ambitious project of refactoring a 27 years old Vim codebase from scratch. You can read more about their vision here.
Ways to install Neovim vary per OS, so it’s better to refer to the original guide. From here on I’ll assume Ubuntu 18.04, but most of the configuration will be OS-independent, only installation steps will be different.
In Ubuntu 18.04 Neovim is included in the distribution, so you can just do

sudo apt-get install neovim

On Mac OS it is available via Homebrew:

brew install neovim

To invoke Neovim, you’d need to call nvim, which is one letter longer than just vim and isn’t compatible with machines where there’s only regular vim available. To fix this you can define an alias in your rc script:

alias vim=’nvim’

I personally chose a hardcore way: deleted a/usr/bin/vim and replaced it with a symlink to the Neovim:

sudo rm /usr/bin/vim && sudo ln -s /usr/bin/nvim /usr/bin/vim

Installing Plug

Before doing anything else with Vim, it’s better to install a plugin manager. I chose vim-plug, because it’s very minimalistic and still does the job. To install Plug for Neovim:

curl -fLo ~/.local/share/nvim/site/autoload/plug.vim --create-dirs

Vim-plug is the only plugin that needs to be added manually, the rest of them will be installed via Plug.

Installing Tmux

The next thing we’ll configure is Tmux. Tmux is a terminal multiplexer, which allows us to do these key things:

  • Split a terminal window into horizontal and vertical panels
  • Split a single terminal into multiple windows
  • Keep all the processes running in Tmux alive, even if we lost an SSH connection.

Tmux runs on the remote side (if we’re talking about development on the remote machine) and is itself split into a tmux-server, and a tmux-client. When you connect to your workstation via SSH, you first laucnh a tmux-client, which then connects to a tmux-server, running on the same machine as a daemon. When the connection drops, SSH terminates only the tmux-client part, as it was the only child started by the SSH process. Now, on Ubuntu 18.04, a fresh enough Tmux is already included in the distribution, so just do:

sudo apt-get install tmux

On other platforms, please make sure you’re installing tmux >= 2.0, as some things in my config are incompatible with older versions.

Installing Zsh

I prefer Zsh over bash, because of few extra features it provides: a command history, shared among all running shells, fancier command autocompletion, and extensibility through oh-my-zsh. On Ubuntu run:

sudo apt-get install zsh

and then make it a default shell for your user:

chsh -s /bin/zsh

(then re-login)

To add oh-my-zsh:

sh -c "$(curl -fsSL"


Who doesn’t love a fuzzy search?

sudo apt-get install git
git clone --depth 1 ~/.fzf

Then just answer yes to everything, and it will make your ZSH fuzzy in several ways. Just try pressing Ctrl+R or Ctrl+T.

~/.zshrc customizations

Here are some things I like to have in my rc file:
