envbot

envbot is a Bash script that, upon changing directory, looks for an .env file in the current working directory and parent directories and sets environment variables accordingly.

Existing environment variables are cached and reset when changing to another directory.

An .env file in a lower directory takes precedence over one in a higher directory.

Installation

Source this script from your .bash_profile or .bashrc.

The format of .env file is as you'd expect, and allows for parameter expansion:

ENVIRONMENT_VAR=value
ENVIRONMENT_VAR2="$PWD/value.txt"

To enable feedback when environment variables are changed, uncomment the following:

# printf "envbot: Set %s=%s\n" "$_name" "$_value"

Todo

• walk up directory structure
• unset prior variables?
• write proper README
