@sbillinge ready for review

Looks good as long as all the edits were brought over correctly!

[cadenmyers13]

@sbillinge compared them side-by-side and the two PRs are the same

[sbillinge]

Let's then implement the method

[cadenmyers13]

@sbillinge ready for review. All tests pass except one that captures the bad output. Im still figuring out how to capture the statement, but wanted to make a push so you can leave comments on function styling and such

[cadenmyers13]

Added new force input param

[cadenmyers13]

I've included a test for the forced overwrite copy of examples.

[sbillinge]

this still seems to be failing tests

[cadenmyers13]

This function name is similar to the copy_examples fucntion except its private and doesnt have an extra s. I left it because its a private function, but let me know if you think we should rename it.

@sbillinge Pytest is passing locally now but this is failing CI for some reason. I'm trying to debug on my fork cadenmyers13#8 and I can't quite figure out whats going on. There is a shell script that runs (requirements/packs/scripts/_pytest.sh) and it calls tar_url.txt which contains this

@Tieqiong Do you know what might be causing this?

FYI, I forgot to pull from upstream before creating this branch so i had to merge the python 3.14 support 🤦‍♂️

[Tieqiong]

@cadenmyers13 seems like tests for srreal and pyobjcryst didn't run, probably not compatible with python 3.14 resulting in installation issue. You can see the test env runs on 3.14, which roots from recent 3.14 update on release-scripts/.github/workflows/_tests-on-pr.yml.
Not quite sure about the ones that got successfully tested though, they are supposed to support only up to 3.13 ... Let's try to add python_version: 3.13 in the test-on-pr workflow for now and see if it passes for now!

We also are out of free credits. Even though CMI is open software, it turns out Mac and Windows builds are not free even then, and CMI running all it's examples burned through our allocation. This is also causing tests to fail, at least the merge to main tests
