cratification: Example support (#8231)
# Description When the crate nu_cmd_lang crate was created last week example_test.rs was copied over from nu_command to nu_cmd_lang. By doing this there was a set of methods in example_test.rs that existed in both crates... This PR removes the redundancy by moving all of those duplicated methods into the crate nu_test_support in a newly created file called example_support.rs _(Thank you for improving Nushell. 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.)_ # User-Facing Changes _(List of all changes that impact the user experience here. This helps us keep track of breaking changes.)_ # 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` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass # 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. |

Re-implement aliases (#8123)
# Description This PR adds an alternative alias implementation. Old aliases still work but you need to use `old-alias` instead of `alias`. Instead of replacing spans in the original code and re-parsing, which proved to be extremely error-prone and a constant source of panics, the new implementation creates a new command that references the old command. Consider the new alias defined as `alias ll = ls -l`. The parser creates a new command called `ll` and remembers that it is actually a `ls` command called with the `-l` flag. Then, when the parser sees the `ll` command, it will translate it to `ls -l` and passes to it any parameters that were passed to the call to `ll`. It works quite similar to how known externals defined with `extern` are implemented. The new alias implementation should work the same way as the old aliases, including exporting from modules, referencing both known and unknown externals. It seems to preserve custom completions and pipeline metadata. It is quite robust in most cases but there are some rough edges (see later). Fixes https://github.com/nushell/nushell/issues/7648, https://github.com/nushell/nushell/issues/8026, https://github.com/nushell/nushell/issues/7512, https://github.com/nushell/nushell/issues/5780, https://github.com/nushell/nushell/issues/7754 No effect: https://github.com/nushell/nushell/issues/8122 (we might revisit the completions code after this PR) Should use custom command instead: https://github.com/nushell/nushell/issues/6048 # User-Facing Changes Since aliases are now basically commands, it has some new implications: 1. `alias spam = "spam"` (requires command call) * **workaround**: use `alias spam = echo "spam"` 2. `def foo [] { 'foo' }; alias foo = ls -l` (foo defined more than once) * **workaround**: use different name (commands also have this limitation) 4. `alias ls = (ls | sort-by type name -i)` * **workaround**: Use custom command. _The common issue with this is that it is currently not easy to pass flags through custom commands and command referencing itself will lead to stack overflow. Both of these issues are meant to be addressed._ 5. TODO: Help messages, `which` command, `$nu.scope.aliases`, etc. * Should we treat the aliases as commands or should they be separated from regular commands? 6. Needs better error message and syntax highlight for recursed alias (`alias f = f`) 7. Can't create alias with the same name as existing command (`alias ls = ls -a`) * Might be possible to add support for it (not 100% sure) 8. Standalone `alias` doesn't list aliases anymore 9. Can't alias parser keywords (e.g., stuff like `alias ou = overlay use` won't work) * TODO: Needs a better error message when attempting to do so # 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` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass # 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.
