direnv

I use the command line a lot. Some projects require different settings, say Python virtual environment, GOPATH for installing go packages and more.

I'm using direnv to help with settings per project in the terminal. For every project I have a .envrc file which specifies required settings, this file is automatically loaded once I change directory to the project directory or any of it's sub directories.

You'll need the following in your .zshrc

if whence direnv > /dev/null; then
    eval "$(direnv hook zsh)"
fi

Every time you create or change your .envrc, you'll need to run direnv allow to validate it and make sure it's loaded. (If you did some changes and want to check them, run "cd .")

Here are some .envrc examples for various scenarios:

Python + pipenv

source $(pipenv --venv)/bin/activate

Go

GOPATH=$(pwd | sed s"#/src/.*##")

PATH=${GOPATH}/bin:${PATH}

This assumes your project's path that looks like /path/to/project/src/github.com/project

If you're using the new go modules (in 1.11+), you probably don't need this.

Python + virtualenv

source venv/bin/activate

Python + conda

source activate env-name

Replace env-name with the name of your conda environment.
