Quick Environment Variable Switcher (Qevs)

Provides a quick way to switch between values for environment variables.

Demo:

Usage

In the directory where you prepared the _qevs/*_options.txt files, run qs.

You can type to filter for the desired option (with fuzzy matching) or click on a choice with your mouse. If you need to set a new value that is absent in the options provided, simply enter it, and Qevs will remember it for the next time.

To unset an environment variable, just hit esc.

Setup

1. Install fzf.
2. For each environment variable X that you want to switch values, create a file named _qevs/X_options.txt, where each line is a possible value for this variable.

For bash, zsh, etc.

Run these lines:

curl https://raw.githubusercontent.com/tslmy/qevs/main/qevs.sh --output ~/bin/qevs.sh && chmod +x ~/bin/qevs.sh
echo 'alias qs="~/bin/qevs.sh && source /tmp/choices.sh && rm /tmp/choices.sh"' >> ~/.profile

For fish

Run these lines:

curl https://raw.githubusercontent.com/tslmy/qevs/main/qevs.fish --output ~/.config/fish/functions/qs.fish
