Warning

Rate limit exceeded

@nimratcoderabbit has exceeded the limit for the number of commits or files that can be reviewed per hour. Please wait 12 minutes and 2 seconds before requesting another review.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Walkthrough

A new Python file semgrep/example.py was added containing a function my_function that prints the sum of two parameters and a class myclass with methods for initialization and checking if a stored value is positive. The file imports os and sys (the latter unused) and ends by calling my_function. Additionally, a new configuration file .coderabbit.yml was introduced specifying review path filters for YAML files.

Changes

File(s)	Change Summary
semgrep/example.py	Added new Python file with `my_function(x, y)` and class `myclass` (`__init__` and `doSomething`).
.coderabbit.yml	Added new config file specifying `reviews.path_filters` for YAML files (`*/.yml`, `*/.yaml`).

Poem

In a file called example, fresh and new,
Functions and classes join the crew.
Numbers add, results appear,
"Positive" echoes, loud and clear.
With code that grows, let’s cheer and clap—
For every script begins with a single tap!
🐇✨

Impact Analysis

Introduction of new function and class in semgrep/example.py

i️ Low 🔗 Impacts API 🔄 Impacts behavior

A new Python file introduces the function my_function, which prints the sum of two arguments, and the class myclass, which provides a method to print whether its internal value is positive. Users can now import and use these new entities in their own code or scripts.

Verify that my_function prints the correct sum for various input pairs and that myclass.doSomething prints the expected output for different values of the internal state. Test importing and using these entities from other modules.

16-16: Ignore outdated class rename suggestion

The call at semgrep/example.py:16 is my_function(1,2), not an instantiation of myclass. A search for myclass( returned no matches in the codebase, so no updates are needed here.

Likely an incorrect or invalid review comment.

In semgrep/example.py around lines 10 to 14, rename the method doSomething to
do_something to follow snake_case naming conventions. Remove the unnecessary
parentheses around the if condition and fix spacing by adding spaces after if
and around the comparison operator. Also, ensure consistent spacing inside the
print statements by removing extra spaces.
