Code Review
This pull request optimizes LaTeX character escaping by hoisting regex compilation and mapping dictionaries to module-level constants in app.py and resume_generator_latex.py. It also includes extensive import reorganization, code formatting for consistency, and documentation of the optimization pattern. A review comment identifies a potential issue in resume_generator_latex.py where importing from the main app module might trigger unintended side effects during standalone execution.

Importing from the main application module app.py within this utility script can trigger unwanted side effects, such as initializing the Flask application, configuring logging, and starting thread pools. This is particularly problematic when resume_generator_latex.py is used as a standalone tool. Per repository guidelines, for standalone scripts, it is preferred to duplicate logic rather than importing from a main application module to avoid these side effects.
References
- For standalone scripts, prefer duplicating logic over importing from a main application module if the import introduces unwanted side effects like app initialization or service connections.

What
Hoist
latex_special_charsmapping and regex compilationre.compileto module-level constantsLATEX_SPECIAL_CHARSandLATEX_ESCAPE_PATTERNinapp.pyandresume_generator_latex.py.Why
The
_escape_latexfunction is called recursively or in loops when generating resumes. Compiling the regex pattern and creating the dictionary inside the function causes these expensive objects to be recreated on every call, which is a performance bottleneck.Impact
Significantly reduces the overhead of
_escape_latexfunction calls, improving performance when generating LaTeX content by eliminating repeated regex compilation.Measurement
This optimization can be measured by comparing the execution time of rendering a large text block with many special characters before and after the change.
