Build traces from ninja builds

Primary LanguagePythonOtherNOASSERTION

This little tool is designed to help shed some light on compile times of targets in Ninja builds.

To use it, just point it at the directory where you call ninja from. It will then attempt to reconstruct the history of your builds, outputting JSON.

Usage

Usage: NinjaTime.py INTPUT [-o|--output OUTPUT]

The INPUT is either a ninja log file, or the directory where ninja was run. I currently only support log format version 5.

The output is a JSON file formatted in a way that chrome tracer can read it. To use the file, open up chrome and navigate to chrome://tracing. Click "Load" and select the generated JSON file.

Contributing

Right now, I think that the best way is to fork the repository and make pull requests.
