crates/uv-python/src/installation.rs

+        match self.implementation() {
+            LenientImplementationName::Known(ImplementationName::PyPy) => "pypy",
+            LenientImplementationName::Known(ImplementationName::GraalPy) => "graalpy",
+            LenientImplementationName::Known(ImplementationName::CPython) => "python",
+            LenientImplementationName::Unknown(_) => "python",
+        }


FYI this duplicates some code found in ManagedPythonInstallation::executable:

uv/crates/uv-python/src/managed.rs

Lines 365 to 369 in a82c210

let implementation = match self.implementation() {

ImplementationName::CPython => "python",

ImplementationName::PyPy => "pypy",

ImplementationName::GraalPy => "graalpy",

};

That other code seems wrong, I think we should just do #14337

Here, I think we should probably do the same thing and make use of

uv/crates/uv-python/src/implementation.rs

Lines 74 to 81 in 2966471

impl<'a> From<&'a LenientImplementationName> for &'a str {

fn from(value: &'a LenientImplementationName) -> &'a str {

match value {

LenientImplementationName::Known(implementation) => implementation.into(),

LenientImplementationName::Unknown(name) => name,

}

}

}

Oh funny, that doesn't work because of cpython, I guess we need a special case for that 😭 I'll push a commit to that pull request for it

It would be a pretty big breaking change to just do this by default. I would think if we wanted to do this we'd want to default to installing it as both python3.12 and pypy3.12, with an option to opt out of the "default" name. This kind of change needs a lot of design work.

zanieb · 2025-06-26T14:44:18Z

The feature is in preview, so we can make changes like this though I agree we need to do some design work to be certain we should. I'm not sure if we should ever install PyPy or GraalPy as python, is that common? We'd definitely need to do some research to understand common patterns there.

I'm not sure if we should ever install PyPy or GraalPy as python, is that common?

I agree, and I don't think it's common. I'm not aware of any way to install PyPy (I have no experience with GraalPy) which would put it on your PATH as python... instead of pypy..., which is what my comment in #13565 about what brew and apt do was referencing.

See also https://doc.pypy.org/en/latest/build.html#installation (emphasis mine):

To install PyPy system wide on unix-like systems, it is recommended to put the whole hierarchy alone (e.g. in /opt/pypy) and put a symlink to the pypy executable into /usr/bin or /usr/local/bin.

Motivated by some code duplication highlighted in #14201, I noticed we weren't taking advantage of the existing implementation for casting to a str here. Unfortunately, we do need a special case for CPython still.

RazerM · 2025-07-24T13:53:52Z

Was this overlooked when the feature was stabilized for 0.8, or you decided pypy- should be installed as python-?

zanieb · 2025-09-25T16:26:41Z

We just didn't get to this, but we should.
