Following up on #7180 with some feature cleanup: - Move the `database` feature from `plugin` to `default` - Rename the `database` feature to `sqlite` - Remove `--features=extra` from a lot of scripts etc. - No need to specify this, the `extra` feature is now the same as the default feature set - Remove the now-redundant 2nd Ubuntu test run

# Contributing
|
|
|
|
Welcome to Nushell and thank you for considering contributing!
|
|
|
|
## Review Process
|
|
|
|
First of all, before diving into the code, if you want to create a new feature, change something significantly, and especially if the change is user-facing, it is a good practice to first get an approval from the core team before starting to work on it.
|
|
This saves both your and our time if we realize the change needs to go another direction before spending time on it.
|
|
So, please, reach out and tell us what you want to do.
|
|
This will significantly increase the chance of your PR being accepted.
|
|
|
|
The review process can be summarized as follows:
|
|
1. You want to make some change to Nushell that is more involved than simple bug-fixing.
|
|
2. Go to [Discord](https://discordapp.com/invite/NtAbbGn) or a [GitHub issue](https://github.com/nushell/nushell/issues/new/choose) and chat with some core team members and/or other contributors about it.
|
|
3. After getting a green light from the core team, implement the feature, open a pull request (PR) and write a concise but comprehensive description of the change.
|
|
4. If your PR includes any use-facing features (such as adding a flag to a command), clearly list them in the PR description.
|
|
5. Then, core team members and other regular contributors will review the PR and suggest changes.
|
|
6. When we all agree, the PR will be merged.
|
|
7. If your PR includes any user-facing features, make sure the changes are also reflected in [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged.
|
|
8. Congratulate yourself, you just improved Nushell! :-)

## Developing
|
|
|
|
### Setup
|
|
|
|
Nushell requires a recent Rust toolchain and some dependencies; [refer to the Nu Book for up-to-date requirements](https://www.nushell.sh/book/installation.html#build-from-source). After installing dependencies, you should be able to clone+build Nu like any other Rust project:
|
|
|
|
```bash
|
|
git clone https://github.com/nushell/nushell
|
|
cd nushell
|
|
cargo build
|
|
```
|
|
|
|
### Tests
|
|
|
|
It is a good practice to cover your changes with a test. Also, try to think about corner cases and various ways how your changes could break. Cover those in the tests as well.
|
|
|
|
Tests can be found in different places:
|
|
* `/tests`
|
|
* `src/tests`
|
|
* command examples
|
|
* crate-specific tests
|
|
|
|
The most comprehensive test suite we have is the `nu-test-support` crate. For testing specific features, such as running Nushell in a REPL mode, we have so called "testbins". For simple tests, you can find `run_test()` and `fail_test()` functions.
|
|
|
|
### Useful Commands
|
|
|
|
- Build and run Nushell:
|
|
|
|
```shell
|
|
cargo run
|
|
```
|
|
|
|
- Build and run with dataframe support.
|
|
```shell
|
|
cargo run --features=dataframe
|
|
```
|
|
|
|
- Run Clippy on Nushell:
|
|
|
|
```shell
|
|
cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect
|
|
```
|
|
|
|
- Run all tests:
|
|
|
|
```shell
|
|
cargo test --workspace
|
|
```
|
|
|
|
- Run all tests for a specific command
|
|
|
|
```shell
|
|
cargo test --package nu-cli --test main -- commands::<command_name_here>
|
|
```
|
|
|
|
- Check to see if there are code formatting issues
|
|
|
|
```shell
|
|
cargo fmt --all -- --check
|
|
```
|
|
|
|
- Format the code in the project
|
|
|
|
```shell
|
|
cargo fmt --all
|
|
```
|
|
|
|
### Debugging Tips
|
|
|
|
- To view verbose logs when developing, enable the `trace` log level.
|
|
|
|
```shell
|
|
cargo run --release -- --log-level trace
|
|
```
|
|
|
|
- To redirect trace logs to a file, enable the `--log-target file` switch.
|
|
```shell
|
|
cargo run --release -- --log-level trace --log-target file
|
|
open $"($nu.temp-path)/nu-($nu.pid).log"
|
|
```
