chrometracing's Issues

open-source existing Java implementation

We have a Java implementation, but I don’t know how to scrub it of internal comments, annotations and dependencies for an open-source release.

I also don’t know whether/how we can properly publish Java open source.

If anyone has a need for the Java implementation, please comment here with details and I can try to find someone who can help open-source the Java implementation.

Properly release Python implementation

We have a Python implementation: https://github.com/google/chrometracing/blob/main/chrometracing.py

…but this implementation is not available as a package one can install via pip, only because I don’t know how to set that up.

add C++ (cmake) support

We have a C++ implementation that needs to be adjusted so that it can be consumed through cmake.
