How to specify extras to install optional-dependencies?

[posutsai]

Hi,
I would like to install the dependencies specified in "optional-dependencies" in pyproject.toml as pyO3-pure. However, I don't know how to add extras argument in maturin develop. There is no related information in help message. Thank you.

maturin develop doesn't support install optional dependencies yet. For now you can do maturin build and using pip to install the wheel to specify extras for example pip install path/to/pyo3-pure.whl[test]'

I think this could be useful feature, any idea what the effort might be to add this ability?

maturin/src/develop.rs

Lines 50 to 67 in b556ed1

	// Install dependencies
	if !build_context.metadata21.requires_dist.is_empty() {
	let mut args = vec!["-m", "pip", "install"];
	args.extend(
	build_context
	.metadata21
	.requires_dist
	.iter()
	.map(|x| x.as_str()),
	);
	let status = Command::new(&interpreter.executable)
	.args(&args)
	.status()
	.context("Failed to run pip install")?;
	if !status.success() {
	bail!(r#"pip install finished with "{}""#, status)
	}
	}

Just need to add optional dependencies here. The question is what to install since you can specify multiple extras with multiple dependencies in pyproject.toml for example:

[project.optional-dependencies]
test = [
  "pytest < 5.0.0",
  "pytest-cov[all]"
]
web = ["flask"]

are you referring to test / web or that pytest-cov[all] is nested in test ?

test / web

how about passing selected extras as arguments for the develop command?

I think it's ok.
