Python library supporting UEFI EDK2 firmware development

Project description

Tianocore Edk2 PyTool Library (edk2toollib)

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.

Content

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.

Examples:

  • 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

Usage

NOTE: It is strongly recommended that you use python virtual environments. Virtual environments avoid changing the global python workspace and causing conflicting dependencies. Virtual environments are lightweight and easy to use. Learn more

  • To install run pip install --upgrade edk2-pytool-library

  • To use in your python code

    from edk2toollib.<module> import <class>
    

Release Version History

Version 0.10.3

  • Features:
    • If multiple classes are found (ie when searching for a SettingsManager), it can now pick the one that is closest to the original module file
    • Unified Azure Pipeline
    • Added Capsule object classes to support decoding and encoding
  • Bugs
    • Catch errors when emitting invalid characters to the markdown log handler
    • Processor info is now checked in a case insensitive manner (fixes OpenBSD)

Version 0.10.2

  • Features:
    • Add GuidList object to allow easy file system parsing of edk2 files for complete list of guids
    • Add gitignore syntax parser to allow for common method to ignore files or folders in tools
  • Bugs:
    • Junit report format module was not escaping all user supplied strings which could cause invalid xml output

Version 0.10.1

  • Bugs:
    • Added better logging when locate_tools queries vcvarsall and can't find a particular key
    • Fixed bug in RunPythonScript that caused an exception
    • Improved XML output by escaping

Version 0.10.0

  • Features:
    • Change DEC parser
      • More complete parser but is not backward compatible. Users of DEC parser will need to update.
      • LibraryClass, Protocol, Ppi, and Guid sections now parse each line to a custom object which contains all data fields.

Version 0.9.2

  • Bugs:
    • Change QueryVcVariables so environment variable keys are not case sensitive. On Windows these are not case sensitive and "Path" is not consistent.

Version 0.9.1

  • Features:
    • Add support for getting WinSdk tools on platforms without VS2017 or newer
    • FindToolInWinSdk in locate_tools.py throws a FileNotFoundException when it cannot find the tool requested, previously it returned None
    • Add support for limiting vswhere to certain versions of visual studio (VS2017 and VS2019 supported)

Version 0.9.00

Initial release of library with functionality ported from Project Mu. For history and documentation prior to this see the original Project Mu project https://github.com/microsoft/mu_pip_python_library
