Please, check our [contributing guide](../CONTRIBUTING.md) and talk to the core team before making major changes. Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> https://github.com/nushell/nushell/pull/9773 introduced constants to modules and allowed to export them, but only within one level. This PR: * allows recursive exporting of constants from all submodules * fixes submodule imports in a list import pattern * makes sure exported constants are actual constants Should unblock https://github.com/nushell/nushell/pull/9678 ### Example: ```nushell module spam { export module eggs { export module bacon { export const viking = 'eats' } } } use spam print $spam.eggs.bacon.viking # prints 'eats' use spam [eggs] print $eggs.bacon.viking # prints 'eats' use spam eggs bacon viking print $viking # prints 'eats' ``` ### Limitation 1: Considering the above `spam` module, attempting to get `eggs bacon` from `spam` module doesn't work directly: ```nushell use spam [ eggs bacon ] # attempts to load `eggs`, then `bacon` use spam [ "eggs bacon" ] # obviously wrong name for a constant, but doesn't work also for commands ``` Workaround (for example): ```nushell use spam eggs use eggs [ bacon ] print $bacon.viking # prints 'eats' ``` I'm thinking I'll just leave it in, as you can easily work around this. It is also a limitation of the import pattern in general, not just constants. ### Limitation 2: `overlay use` successfully imports the constants, but `overlay hide` does not hide them, even though it seems to hide normal variables successfully. This needs more investigation. # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> Allows recursive constant exports from submodules. # Tests + Formatting <!-- Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect -A clippy::result_large_err` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass - `cargo run -- -c "use std testing; testing run-tests --path crates/nu-std"` to run the tests for the standard library > **Note** > from `nushell` you can also use the `toolkit` as follows > ```bash > use toolkit.nu # or use an `env_change` hook to activate it automatically > toolkit check pr > ``` --> # After Submitting <!-- If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. --> |
