Implement `uv pip freeze --exclude` flag by gaardhus · Pull Request #17045 · astral-sh/uv

gaardhus · 2025-12-09T10:20:22Z

Summary

Implements the --exclude flag to uv pip freeze, which allows to filter unwanted dependencies from the resulting requirements.txt file.

uv pip freeze --exclude pandas

part of #3141

Test Plan

Unit test with simple exclusion example of command argument(s)

crates/uv/src/commands/pip/freeze.rs

 /// Enumerate the installed packages in the current environment.
 pub(crate) fn pip_freeze(
    exclude_editable: bool,
+    exclude: &[PackageName],


Should this be a hash set instead?

crates/uv/src/settings.rs

 #[derive(Debug, Clone)]
 pub(crate) struct PipFreezeSettings {
    pub(crate) exclude_editable: bool,
+    pub(crate) exclude: Vec<PackageName>,


I presume we'd transform to a hash set here

+    let requirements_txt = context.temp_dir.child("requirements.txt");
+    requirements_txt.write_str("MarkupSafe==2.1.3\ntomli==2.0.1")?;
+
+    // Run `pip sync`.
+    context
+        .pip_sync()
+        .arg(requirements_txt.path())
+        .assert()
+        .success();


I might just pip install these packages instead since it's simpler, and you don't need to pin versions because we use exclude-newer in the test suite.

changed to pip_install, and can also remove pins, however I just adopted that from the other test cases, so unsure how to move forward with that.

As in https://github.com/astral-sh/uv/pull/17045/files#r2614916235 we can just open an issue to simplify some of the test cases.

crates/uv/src/settings.rs


        Self {
            exclude_editable,
+            exclude,


transform to hash set here seems to be how I can make it work? exclude: exclude.into_iter().collect(),

however, like pinning versions in pip_install test, I'm unsure if other similar cases should be changed, i.e. PipListSettings implements a similar exclude argument which is also currently a Vec.

@zanieb

We can pursue refactoring other cases separately, want to just open an issue to track that?

+    context
+        .pip_install()
+        .arg("-r")
+        .arg("requirements.txt")


I think you should drop the requirements.txt entirely and just use MarkupSafe and ntomli as arguments here.

@zanieb Sorry for the delayed response. I have rebased on main and created two issues, let me know if anything else is missing.

zanieb · 2026-01-17T15:34:23Z

Thanks!

Further simplify pip_freeze tests by passing package names directly to pip_install rather than creating temporary requirements files. This follows the suggestion from PR astral-sh#17045 review discussion.
