BBL Zsh and other command line goodies

Notes on the "how", complementing the demo about the "why".

Make Zsh the default shell

chsh -s $(which zsh)

Install Oh-My-Zsh

ohmyz.sh

Plugin manager and other cool things.

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Theme

Font with usefull icons

www.nerdfonts.com / downloads

Install a "Nerd Font", with usefull icons included, then configure your terminal to use it. I recommend JetBrainsMono Nerd Font.

Fast and highly customizable theme

Don't use the one provided, they are obsolete and slow. I recommend Powerlevel10k which is fast, have great defaults, a simple configuration form (in command line), and can be customized to look like some other popular ones like pure.

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git $ZSH_CUSTOM/themes/powerlevel10k

Set ZSH_THEME="powerlevel10k/powerlevel10k" in ~/.zshrc.

Launch Zsh and complete configuration.

gitfast

Simpler and faster git integration plugin.

Just add gitfast to the .zshrc plugin list (plugins=(...)).

Fasd

GitHub clvv/fasd / Installation

Like autojump and z, fasd adds more command line for quick action (cd / vim / open / etc) by letting the machine figure out what file or folder you are talking about, loosely matching your history.

Some commands :

z
- smart cd
v
- smart vi
o
- smart open file
f
- smart print full path (to incorporate fasd intelligence in other command)

See link for install depending on your OS, then add fasd to the .zshrc plugin list (plugins=(...)).

zsh-autosuggestions

GitHub zsh-users/zsh-autosuggestions / Installation

Autocompletion suggestions.

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Then add zsh-autosuggestions to the .zshrc plugin list (plugins=(...)).

TheFuck

GitHub nvbn/thefuck / Installation

After a botched command, type fuck to have suggestions on the corrected command, and validate the new one with enter. For exemple, with a failed git push new_local_branch, it proposes automatically the better git push --set-upstream origin new_local_branch.

After installation, add this to your ~/.zshrc :

eval $(thefuck --alias)

Python Pyenv

GitHub pyenv/pyenv / Installation

After installation, add this to ~/.zshrc

export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
# pyenv-virtualenv: prompt changing will be removed from future release.
# configure to simulate the behavior.
export PYENV_VIRTUALENV_DISABLE_PROMPT=1

Then add pyenv in the plugin list already in this file (plugins=(...)).

Fix powerlevel10k right prompt

If you use a powerlevel10k theme, you might have duplicated information (virtualenv + pyenv). In your ~/.p10k.zsh file, comment out virtualenv from POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS.

Specific pip conf by pyenv environment

If some of your pyenv environment needs a specific pip conf but not all of them, you can create a function which configure the current pyenv environment with a specifice pip conf like this :

# Set a specific pip conf for the current pyenv environment
setspecificpipconf () {
   ln -s /XXX/SPECIFIC_pip.conf `pyenv prefix`/pip.conf
}

Bat

GitHub sharkdp/bat / Installation

Like cat, but with syntax highlighting and git status line indicator.
