    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.
