If you are working in terminal - one of the important things is to keep your scripts and dotfiles in the order. Basically, you should consider them as one of your regular pet/side projects, and as any other of your pet projects:

  • you should be able to easily contribute to it;
  • you should have a good way to maintain dependencies;
  • you should make it reusable;

I am a Terminal user, I use combination of tmux, zsh and vim for everyday development. In this post I just want to share with you my dotfiles and few ideas/plugins I use to maintain my scripts and configuration. Hope that it may be useful for you as a reference.

Also I published two of my cheatsheets: vim and tmux

iTerm2

What to use?

If you were Windows user as me you probably have heard a lot of “Linux is great because it has bash”. And that is true, bash is great, but it is not only one shell is installed on your system (I’m on OS X 10.11)

# ls /bin/*sh
/bin/bash /bin/csh  /bin/ksh  /bin/sh   /bin/tcsh /bin/zsh

It is one of the popular, but there are alternatives. One of the alternatives is zsh. You probably have heard about oh-my-zsh which people blindly install because of nice prompts you can get with it. But it is much more than just a theme for your prompt. It is a good tool to manage your dotfiles, scripts and configurations, but it works better if you understand why you install it and which tools works great with it.

zsh

Zsh is a shell designed for interactive use, although it is also a powerful scripting language.

Why people choose zsh over bash?

Short answer: if we will compare it to bash it has much better competition and expansion. For some reason OS X also has very outdated version of bash.

Long answer: to see all benefits of zsh read From Bash to Z Shell or at least start with Master Your Z Shell with These Outrageously Useful Tips.

bash and zsh are very similar in syntax and most of builtin commands are the same, but you need to know that not everywhere you will be able to get zsh, somewhere you maybe will not have access to bash only sh.

oh-my-zsh

A delightful community-driven framework for managing your zsh configuration. Includes 200+ optional plugins (rails, git, OSX, hub, capistrano, brew, ant, php, python, etc), over 140 themes to spice up your morning, and an auto-update tool so that makes it easy to keep up with the latest updates from the community.

One of the reasons why I use oh-my-zsh because of great set of plugins. Also as we already discussed it has nice themes. Also I highly recommend to take a look on cheatsheet.

tmux

tmux is a terminal multiplexer

What is a terminal multiplexer? It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal. And do a lot more. See the manual.

If you are Mac user you probably know about iTerm2. It has integration with tmux. If you really want to feel benefit of tmux and make your life easier don’t use integration. You will not get benefit of tmux if you will cheat with iTerm2 and still use mouse for few things. And don’t just try tmux, if you really want to get benefit from tmux - you should read some docs, maybe this book tmux. Productive Mouse-Free Development.

Vim

Vim - the editor

Vim is great. Will you believe me that I was a heavy Visual Studio / ReSharper user, command line any non IDE editor hater and now I am happy vim user?

Vim itself is great editor (especially considering how many plugins it has). But it requires a lot of time to learn it. My timeline of learning vim was:

  1. What is that, how do I exit it? When I started to learn git I just had a rule to never commit without -m, because I could not understand how to exit this git editor. Yes exactly, the git editor, this is what I used in my Google searches to find how to exit it. I had no idea that it was Vim.
  2. I installed, learned how to exit it, learned about two modes and started to tell people that I know Vim. I was able to write a git commit message and even edit few configuration files.
  3. I read few articles and installed a lot of plugins. I was a little bit more advanced Vim lammer. Plugins made Vim look cool and I started to enjoy it more. I making Vim to look more like any non-Vim editor.
  4. I read few vimrc files, read more articles about Vim, and more important I have read Practical Vim. I wrote my own vimrc file and started to use Vim for small things like: small updates in source code, conf files, writing markdown text.
  5. My current stage. I’m very careful about plugins, before installing them at first I read docs and configure them in the way I think it should work. I feel more comfortable with Vim and Pythong-mode than with PyCharm, or Vim and Vim-go than with Sublime Text, or using Vim for C++ development than Xcode.

One more important thing, use Vim in terminal, don’t use MacVim. MacVim is great but if you want to be really productive you should learn Vim in terminal, using it with tmux is really great combination.

To manage plugins for Vim I use vundle.

git

Git is great for managing your own scripts and dotfiles. You want to have a history and you want to have a very simple way to sync changes between multiple work environments. Using public git repositories is hard for dotfiles, I prefer to keep my dotfiles private, because it is easy to keep private things in private repository, like some functions/scripts for new feature I’m working on right now. Or maybe links to private company websites and repositories. I tried at first to write some kind of dotfiles framework which can be reusable and easy to maintain, but considering how often you change things - it is really hard to do.

zgen

Most of the peoples use antigen, which looks more like dead than alive. It has huge issue with performance, depending on how many plugins you defined in your zshrc file - antigen can spend more than few seconds in parsing its sugar syntax. But at the end I just switched to zgen, which is much faster. The only one problem with zgen if you update your zshrc file you need to reset the cache with zgen reset. I had only one issue with it, when you are switching to root, but author took my pull request so no more issues.

My setup

Installation

I store my dotfiles in Git on my own GitLab server at home. On any computer with zsh I clone my repository in ~/.dotfiles

git clone \
    ssh://git@gitlab.example.com/outcoldman/dotfiles.git \
    ~/.dotfiles \
    --recursive

Content of cloned folder is

.git/
.gitignore
.gitmodules
dots/
install.zsh*
plugins/
powerline-fonts/
scripts/
settings/
vim/
zgen/

I have two submodules zgen and powerline-fonts. I may consider to actually move them to install.zsh script, so it will be easier to work with them. But for now they are submodules.

Also in the root folder I have

  • dots - my dotfiles
  • plugins - my zsh plugins
  • scripts - few python / shell / some other scripts I downloaded / wrote.
  • settings - folder to sync Alfred, iTerm and Sublime Text (I keep Sublime just in case if somebody else will need to use my computer).

My install.zsh looks like

#!/bin/zsh

# Change shell for current user to zsh
if [ ! "$SHELL" = "/bin/zsh" ]; then
  chsh -s /bin/zsh
fi

# remove old dot files
rm ~/.gitconfig
rm ~/.gitignore_global
rm ~/.tmux.conf
rm ~/.vimrc
rm ~/.zshrc

# link new dot files
ln ~/.dotfiles/dots/home/gitconfig               ~/.gitconfig
ln ~/.dotfiles/dots/home/gitignore_global        ~/.gitignore_global
ln ~/.dotfiles/dots/home/tmux.conf               ~/.tmux.conf
ln ~/.dotfiles/dots/home/vimrc                   ~/.vimrc
ln ~/.dotfiles/dots/home/zshrc                   ~/.zshrc

# Do special to sync sublime settings on OS X
if [[ "$OSTYPE" =~ "darwin" ]]; then
  rm ~/Library/Application\ Support/Sublime\ Text\ 3/Packages/User

  ln -s ~/.dotfiles/settings/SublimeText/User      ~/Library/Application\ Support/Sublime\ Text\ 3/Packages/User
fi


# install powerline fonts
~/.dotfiles/powerline-fonts/install.sh

Just to be clear here and later I clear listing of all files from information which I consider unnecessary, like work specific.

zshrc

Let’s take a look on the content of zshrc

#!/bin/zsh

# If I see that zsh takes to much time to load I profile what has been changed,
# I want to see my shell ready in not more than 1 second

setopt printexitvalue
# Do not share history
setopt no_share_history

# if profiling was on
if $PROFILING; then
    zprof
fi

As you can see I keep all my custom plugins under plugins folder, all of my plugins just some set of functions like my-brew/my-brew.plugin.zsh

#!/bin/zsh

brew-essentials() {
  brew install cloc
  brew install cmake
  brew install coreutils
  brew install ctags
  brew install cv
  brew install docker
  brew install docker-compose
  brew install docker-machine
  brew install git
  brew install gotags
  brew install hr
  brew install httpie
  brew install icdiff
  brew install jq
  brew install lnav
  brew install mercurial
  brew install ncdu
  brew install node
  brew install p7zip
  brew install pstree
  brew install pyenv
  brew install ranger
  brew install rbenv
  brew install ruby-build
  brew install sqlite
  brew install ssh-copy-id
  brew install the_silver_searcher
  brew install tmux
  brew install vim
  brew install watch
  brew install zsh
}

Or for example some of them to work in special configurations like my-aws/my-aws.plugin.zsh (another reason to keep my dotfiles private)

#!/bin/zsh

# Docker
docker-machine-aws() {
    export AWS_ACCESS_KEY_ID=MY_AWS_KEY
    export AWS_SECRET_ACCESS_KEY=MY_AWS_SECRET
    export AWS_VPC_ID=MY_VPC_ID
    export AWS_DEFAULT_REGION=us-west-2
}

For securtiy reasons I do not recommend to export these variables every time your zsh profile is loading. Only load it in sessions where you really need it.

Some plugins automatically load special things, like tpm/tpm.plugin.zsh

#!/bin/zsh

# If Tmux Plugin Manager is not installed - clone it
if [[ ! -d ~/.tmux/plugins/tpm/.git ]]; then
    git clone git@github.com:tmux-plugins/tpm.git ~/.tmux/plugins/tpm
fi

Also I have my special plugin which load oh-my-zsh tmux plugin only when I’m not in SSH and not root

#!/bin/zsh

# It takes control, so load last
# Load only when we are default user (not root) and not in ssh
if [[ ${DEFAULT_USER} == ${USER} ]] && [[ -z ${SSH_CLIENT} ]]; then
    source $ZSH/plugins/tmux/tmux.plugin.zsh
fi

tmux.conf

As you have seen I use Tmux Plugin Manager for tmux, which allows me to load few things from Tmux.

# List of plugins

# These are all plugins I load from GitHub, first is Tmux Plugin Manager
set -g @plugin 'tmux-plugins/tpm'

# Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
run '~/.tmux/plugins/tpm/tpm'

I also use tmuxinator to predefine some common used session.

Here also my tmux cheatsheet.
