Fancy ZSH config

A fancy ZSH config that fits my needs.

Install locally

On a multi-user system you'll want to install this just for your user.

• Clone this repo to ~/.zsh (use --recursive to install the submodule)
• ln -s ~/.zsh/.zshrc ~/.zshrc

To run custom code, the easiest solution is replacing the .zshrc symlink with an actual file which sources ~/.zsh/.zshrc before running the custom code.

Install globally

If you are the only user of a machine, it might be nice to install it globally for all users (such as your primary user, root, and any other account you might use).

• Clone this repo using to /etc/zsh/custom (use --recursive to install the submodule)
• ln -s /etc/zsh/custom/.zshrc /etc/zsh/zshrc
• ln -s /etc/zsh/custom/.zshenv /etc/zsh/zshenv (to disable the new-user wizard)

Depending on your distribution you might need to use /etc/zshrc and /etc/zshenv instead of the paths shown above.

Autovenv

Loading Python virtualenvs is monkey work. The typical Linux user is not a monkey. You can create a ~/.autovenv file containing virtualenv path mappings which will automatically load the specified virtualenv if you are inside the specified directory. The syntax is quite simple:

# By default we want a Python 2 virtualenv
DEFAULT                 ~/.python2-env
# Misc scripts are using Python 3 though
~/dev/misc              ~/.python3-env
# The coolproject folder has an `env` subdirectory
~/dev/coolproject       env
# In /tmp we don't manage the virtualenv at all
/tmp                    IGNORE

The default DEFAULT is is to IGNORE the virtualenv. The only other value with a special meaning is GLOBAL which will deactivate any active virtualenv.

The autovenv check runs in a chpwd hook so after editing the file you will have to cd . to trigger it if you are already in the directory you added.

Note: You cannot use pyenv-virtualenv and autovenv simultaneously as having two utils activating/deactivating virtualenvs is a source for problems. You can either disable autovenv by not having a ~/.autovenv file or pyenv-virtualenv by not running its init command (nor putting it in your ~/.zshrc). Using plain pyenv is fine by the way.

Prompt

The hostname color in the prompt can be overridden by setting ZSH_HOST_COLOR to any value that's allowed inside %F{...}.
