🐛 Run prek from root of target repository

[denialhaag]

Description

This PR fixes a bug encountered in munich-quantum-toolkit/core#1790. Because prek is not running from the current directory, it cannot find the pre-commit and rumdl configurations in the target repository. This PR fixes this by setting the cwd argument of subprocess.run.

Warning

Review limit reached

@denialhaag, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 45 minutes and 50 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

📝 Walkthrough

Walkthrough

_render_template is updated to accept target_dir instead of a pre-computed output_dir. It now constructs the output file path internally from target_dir and runs the prek run formatting subprocess with cwd=target_dir. CHANGELOG.md records this as the 1.3.1 release.

Changes

prek working directory fix

Layer / File(s)	Summary
_render_template signature and cwd fix src/mqt/templates/render_templates.py	render_templates now passes target_dir to _render_template instead of a pre-computed output_dir. _render_template's signature changes from output_dir to target_dir, and the output path is rebuilt as target_dir / template_container.output_dir / template_container.file_name. The prek run subprocess is invoked with cwd=target_dir.
CHANGELOG 1.3.1 release entry CHANGELOG.md	A new 1.3.1 release section with a "Fixed" entry for the prek working-directory change is added; the [unreleased] compare link and [1.3.1] release tag link are updated; PR #344 is appended to the reference list.

Poem

🐇 Hop, hop, said the rabbit with glee,
Now prek runs where the target should be!
No more lost in a faraway dir,
The right cwd brings us back to what's clear.
The changelog is stamped: 1.3.1—hooray!
Fixed and released on this fine summer day! 🌿

In `@src/mqt/templates/render_templates.py`:
- Around line 266-270: The subprocess.run call for prek is passing the full
output_path (which already includes target_dir) while also setting
cwd=target_dir, causing prek to receive a doubly-prefixed path when target_dir
is relative. Fix this by computing the relative path of output_path from
target_dir and passing that relative path to the prek subprocess instead of
passing str(output_path). Use output_path.relative_to(target_dir) to get the
correct relative path argument to pass to the --files option.
