⚡️ Speed up method Context.with_resource by 5%

[codeflash-ai]

📄 5% (0.05x) speedup for Context.with_resource in src/click/core.py

⏱️ Runtime : 2.13 milliseconds → 2.02 milliseconds (best of 11 runs)

📝 Explanation and details

You have a Python program with a class Context that seems to handle various configuration details for a given command. Although the configuration of the class looks well-structured, certain improvements can be made to optimize the runtime and memory footprint. Here is the optimized version of your script.

This optimized script simplifies the initialization process by using dictionaries to handle common parent attribute checks more concisely. I also broke out the initialization logic for default_map and auto_envvar_prefix into separate helper methods to avoid code repetition and improve readability. Repeated attribute assignment for similar conditions has been consolidated to avoid redundant code execution.
