pyrformance

Linter that makes your Python code faster.

Pyrformance is a collection semgrep rules and a thin wrapper on top of semgrep CLI for a simple way of running these rules. All rules are non-opinionated and performance-focused.

Features:

• Non-opinionated. If pyrformance reports something, changing it will make your code faster. That's it. It won't tell you to change something just because it's a "pythonic", consistent, or whatever else.
• Benchmarked. For each rule, we have a true-north-powered benchmark that shows that the rule indeed makes code faster. We don't play guessing or advice something just because a random Medium article says so.
• Tested. We have tests for each rule, which is quite unusual for semgrep-rules you can find in the wild.
• Never compromises readability. We do our best to not recommend any changes that would make the code less readable, even if that would be faster.

Installation

python3 -m pip install pyrformance

Usage

python3 -m pyrformance ./your_project/
