Python library supporting UEFI EDK2 firmware development

Project description

Tianocore Edk2 PyTool Library (edk2toollib)

pypi codecov ci docs

This is a Tianocore maintained project consisting of a python library supporting UEFI firmware development. This package's intent is to provide an easy way to organize and share python code to facilitate reuse across environments, tools, and scripts. Inclusion of this package and dependency management is best managed using Pip/Pypi.

This is a supplemental package and is not required to be used for edk2 builds.

Current Status

codecov ci

The code coverage and CI badges represent unit test status and the code coverage of those unit tests. We require 100% unit test success (Hence the pass / fail) and that code coverage percentage does not lower.

Current Release


All release information is now tracked with Github tags, releases and milestones.


The package contains classes and modules that can be used as the building blocks of tools that are relevant to UEFI firmware developers. These modules should attempt to provide generic support and avoid tightly coupling with specific use cases. It is expected these modules do not provide direct interaction with the user (through command line interfaces) but instead are intended to be wrapped in other scripts/tools which contains the specific usage and interface.


  • File parsers for edk2 specific file types. These parse the file and provide an object for interacting with the content.
  • UEFI specific services for encoding/decoding binary structures.
  • UEFI defined values and interfaces for usage in python
  • Python wrappers for other system cli tools ( signtool, catalog file generation, inf file generation, etc)
  • Python utilities to provide consistent logging, command invocation, path resolution, etc

  1. Contributor opens an issue describing problem or new desired functionality
  2. Contributor forks repository in github
  3. Contributor creates branch for work in their fork
  4. Contributor makes code changes, writes relevant unit tests, authors documentation and release notes as necessary.
  5. Contributor runs tests locally
  6. Contributor submits PR to master branch of tianocore/edk2-pytool-library
    1. PR reviewers will provide feedback on change. If any modifications are required, contributor will make changes and push updates.
    2. PR automation will run and validate tests pass
    3. If all comments resolved, maintainers approved, and tests pass the PR will be squash merged and closed by the maintainers.

Users and Consumers

Documentation for the most recent release of edk2-pytool-library is hosted on Raw documentation is located in the docs/ folder and is split into two separate categories. The first is located at docs/user/ and is documentation and API references for those that are using this package in their own project. Users can generate a local copy of the documentation by executing the following command from the root of the project:

pip install --upgrade -e .[docs]
mkdocs serve


Contributor documentation is located at docs/contributor/ and contains instructions for:

  • Setting up a development and testing environment
  • How edk2pytools is versioned and published
  • Contributing to the edk2-pytool-extensions repository
