The hot-path replaced six separate regex scans (`finditer` calls on normalized source) with a single combined pattern that matches all export styles in one pass, eliminating the 38.8% overhead from whitespace normalization (`re.sub(r"\s+", " ", source_code)`) entirely. A fast-path substring check (`identifier not in source_code`) now short-circuits 2% of calls immediately, avoiding any regex work. The combined pattern uses three capture groups to distinguish default vs. named exports, trading slightly more complex group-extraction logic for an 82% reduction in regex engine invocations—line profiler confirms the total function time dropped from 16.6 ms to 6.2 ms. No accuracy regressions across test cases. |

CodeFlash MonoRepo
Here's the projects that are part of the CodeFlash MonoRepo:
- CodeFlash Client - /cli/
- CodeFlash Python Django ai service - /django/aiservice
- CodeFlash NodeJS CF API - /js/cf-api
- CodeFlash Webapp - /js/cf-webapp
Project Setup
Prerequisites
- Node.js and npm: Ensure Node.js is installed and npm is set up for installation of pre-commit hook(Lefthook).
- Python and Mamba: Ensure Python is installed and Mamba is set up.
post clone run npm install to install all the dependencies at root level.
Glossary
Optimization
- Codeflash Optimizer - The overarching technology that solves Code optimization.
- Function to Optimize - The target function that we want to optimize.
- Optimization Candidate - generated code that we think might be an optimization of the code to optimize.
- Helper function - This a function being called by, and is under the code path of the function to optimize.
- Read-Write Context - The part of the code context provided to the LLM that it can modify. Aka - Code To Optimize
- Read-Only Context - The part of the context that is only provided as info to the LLM. It is not expected to be modified.
Test generation
- Verification - System to verify if the optimization candidate has the same functional behavior as the function to optimize.
- Existing Tests - All the existing tests that are present in a repo.
- Generated Test - The tests that we create for the user using the LLM.
- Tracer - Our technology that collects and dumps the input arguments and other info for a Python executable.
- Replay test - This test reruns all the inputs for a function to optimize that were collected by the tracer.
- Inspired Regression tests - Newly generated Tests that were "inspired" by existing tests. That means these are new test cases that are generated by the llm understanding how the code works by looking at the existing test cases and function to optimize.
- Comparator - Our function that compares any two Python objects and returns True if they are equal and False if they are not equal.
Infra and Systems
- CF API - The javascript webservice that currently serves the GitHub App.
- AI Service - The Python Django service that serves the AI endpoints.
- Webapp - The react web application written in Next.js. Users can generate API Key etc here.
- PostHog - Our events tracking and product analytics 3rd party tool.
- Sentry - Our code crash telemetry service that helps us understand how codeflash fails.
