Swytchit

Switch environment context easily in the shell

Usage

sw your/project/directory

• Performs a cd operation to the project
• Starts a subshell
• Within the subshell, runs source on .swytchitrc.sh files in the project directory and any ancestor directories

Use the exit command when done with the project to exit the subshell and clear the environment.

Note that .swytchitrc.sh can support any source operation, including:

• Set environment variables
• Define aliases
• Define functions

Why?

• Easily switch virtual environments for scripting languages (Python, Ruby, etc)
• Easily populate project-specific environment variables and aliases
• Use with the op CLI from 1Password to keep project-specific secrets in memory

Installation (MacOS)

brew install pipx
pipx install swytchit

Also do a profile/rc song and dance something like this:

echo 'if [[ -n $SWYTCHITRC ]]; then source $SWYTCHITRC; fi' >> $ZDOTDIR/.zshrc
source $ZDOTDIR/.zshrc

(use e.g. .profile or .bashrc if not on zsh)

Rules

• Only works in TTY shell (no piping)
• Only works for a descendent of user's home directory
• Resolves symlinks first
