Abstract
--------

Stop wrestling with regular expressions (regex) and complex abstract syntax tree  
(AST)-based frameworks to analyze and lint your Python code! Chasten offers an  
elegant solution by leveraging XPath expressions to search Python's abstract  
syntax tree, making static code analysis both powerful and accessible. In this  
talk, you'll discover how to implement custom linting rules, enforce coding  
standards, and perform sophisticated pattern matching in your Python projects  
using a tool designed for both simplicity and flexibility. Whether you're a  
developer tired of writing fragile regex patterns, an instructor validating  
student code, or a project maintainer who wants to ensure code quality, Chasten  
provides the perfect balance of power and usability for your static analysis  
needs. More details about chasten are available at:  
https://github.com/AstuteSource/chasten.

Key Takeaways
-------------

* Create custom linting rules through simple YAML configuration
* Practical examples of enforcing code standards on documentation and code
* Ways to analyze results through interactive dashboards with Datasette
* How to integrate Chasten into development workflow and CI/CD pipelines
