envy

Shell helper that automatically sets and unsets environment variables

Envy is a shell helper program that automatically sets environment variables when you enter certain directories, and properly undoes its actions when you leave them. Envy can be used to replace the shell integration part of tools like pyenv, nvm and asdf. It sets environment variables with the root of the current git repository and the active branch without executing git, which you can use to customize your shell prompt. It also loads custom environment variables from local .envy files.
