Environment Variables

These variables are available as environment variables in scripts run by melos exec. They can also automatically replaced/injected on melos exec commands e.g. melos exec --file-exists="./test_driver/MELOS_PARENT_PACKAGE_NAME_e2e.dart" --scope="*example*" -- echo hello

MELOS_PARENT_PACKAGE_NAME

The name of the parent package of the current package that's currently executing a script (when using melos exec).

MELOS_PARENT_PACKAGE_VERSION

MELOS_PARENT_PACKAGE_PATH

What is a 'parent package'

If a package exists in a directory that is also a child of another package, then its parent is the 'parent package'. For example; the package firebase_auth has a example directory that is also a package, when running a melos exec script in the example package then the parent package would be firebase_auth.

Note, this 'parent package' functionality only currently works when the 'child package' name ends with example

User Defined

MELOS_PACKAGES
