Loading the Environment into Your Shell

This is the job mulle-sde and mulle-env do for you automatically. But you can do this also manually.

After editing environment files, you need to source them to apply the changes to your shell:

# Source the environment into your current shell
cd /path/to/your/project
. .mulle/share/env/environment.sh

This will load all environment variables according to their priority and scope applicability.

Testing Environment Without Affecting Your Shell

To preview what environment variables will be set without modifying your current shell:

# Run in a clean environment and display all variables
env -i bash -c '. .mulle/share/env/environment.sh && env | sort'

# Or export from the editor and test the exported script
env -i bash -c '. environment-export.sh && env | sort'

The env -i command starts with an empty environment, so you can see exactly what the environment files set up.

Environment File Structure

The editor works with mulle-env environment file structure:

.mulle/etc/env/           # Local environment files
├── environment-project.sh
├── environment-global.sh
├── environment-host-*.sh
├── environment-user-*.sh
├── environment-os-*.sh
└── auxscope              # Loading order configuration

.mulle/share/env/         # Shared environment files
├── environment-extension.sh
├── environment-plugin.sh
└── environment.sh
