Questions tagged [abseil]

Abseil is an open-source utility library available for the Python and C++ languages, maintained and released by Google. The code comes from Google's own code base and existing projects. When using this tag, also include a tag indicating the language in which you are using Abseil utilities (Python or C++).

Abseil's C++ libraries are culled from utilities in Google's internal codebase. Abseil's Python libraries replace the no-longer-maintained google-apputils Python module, which contained useful Python utilities.

Links

  • Github repo for Abseil Common Libraries in C++: abseil-cpp
  • Github repo for Abseil Common Libraries in Python: abseil-py
  • Github organization for Abseil: abseil

The documentation will eventually be at abseil.io but there is currently no documentation available.
