envmng is a tool for managing shell environments. I made it because I was fed up by the slow start-up time my shell was exhibiting.
stack install
Add the following snippet to your .zshrc, .bashrc, or similar:
envmng() {
eval $(envmng-exe "$@")
}envmng +d
envmng +ruby
envmng -java
envmng-exe --help
envmng-exe list
