Build actions

The build actions allow for building artifacts for a Python library. These artifacts include both source distribution files and wheels.

Build library action

Verifies if a Python library builds properly. As a result of a successful building process, wheel and source distribution artifacts are generated. This action is expected to be used as an independent job.

Note

Use this action instead of the build-ci-wheels if your library is a pure Python project with no source code to be compiled.

Source code for this action

Input	Description	Required	Type	Default
library-name	Name of the Python library. This is the name used when uploading the wheel and source distribution as artifacts. The name should be the same one used in the PyPI index.	True	string
python-version	Python version used for installing and execution of the build process.	False	string	3.1
use-python-cache	Whether to use the Python cache for installing previously downloaded libraries. If true, previously downloaded libraries are installed from the Python cache. If false, libraries are downloaded from the PyPI index.	False	boolean	1
validate-build	Whether to validate the build process. If true, the build process is validated. If false, the build process is not validated.	False	boolean	1

Examples

Build library basic example

build-library:
  name: "Build library basic example"
  runs-on: ubuntu-latest
  steps:
    - name: "Build library source and wheel artifacts"
      uses: ansys/actions/build-library@v6.0
      with:
        library-name: "ansys-<product>-<library>"

Build wheelhouse action

Generates compressed artifacts for the wheelhouse of a Python library. The wheelhouse contains all the necessary dependencies to install the project. This allows for local installations and avoids the need to connect to the online PyPI index.

Warning

Since version 4.1, the input parameter library-namespace is no longer required.

Source code for this action

Input	Description	Required	Type	Default
library-name	Name of the Python library. This is the name used when uploading the wheel and source distribution as artifacts. The name should be the same one used in the PyPI index.	True	string
operating-system	Name of the operating system where the library is installed.	True	string
python-version	Python version used for installing and execution of the build wheel process.	True	string
target	Optional target used during the building process.	False	string
use-python-cache	Whether to use the Python cache for installing previously downloaded libraries. If true, previously downloaded libraries are installed from the Python cache. If false, libraries are downloaded from the PyPI index.	False	boolean	True
check-licenses	Whether to check the library’s dependencies license or not. If true. the licenses are checked. If false, no license check is performed. By default it is set to true.	False	boolean	True

Examples

Build wheelhouse for latest Python versions

build-wheelhouse:
  name: "Build wheelhouse for latest Python versions"
  runs-on: ${{ matrix.os }}
  strategy:
     matrix:
         os: [ubuntu-latest, windows-latest]
         python-version: ['3.7', '3.8', '3.9', '3.10']
  steps:
    - name: "Build a wheelhouse of the Python library"
      uses: ansys/actions/build-wheelhouse@v6.0
      with:
        library-name: "<ansys-product-library>"
        operating-system: ${{ matrix.os }}
        python-version: ${{ matrix.python-version }}

Build CI wheels action

Build wheels for a Python library containing compiled source code. This action is expected to be used within a matrix job. Its goal is to generate wheel files for every combination of operating system, build system, and Python version. The action uses the cibuildwheel behind the scenes.

Note

This actions should only be used by libraries including source code that needs to be compiled.

Source code for this action

Input	Description	Required	Type	Default
python-version	Python version used for building the wheels.	True	string
cibw-build	Desired build wheel CPython version.	False	string	cp310-*
cibw-skip	Desired conditions to skip when building the wheels.	False	string	-musllinux
cibw-archs	Desired build architecture.	False	string	auto
requires-pypy	Whether to generate wheels for wheel files for PyPy in addition to the wheel files for CPython. Default value is false.	False	boolean	False

Examples

Build a C-extension library

build-c-extension:
  name: "Build a C-extension library"
  runs-on: ${{ matrix.os }}
  strategy:
     matrix:
         os: [ubuntu-latest, windows-latest, macos-11]
  steps:
    - name: "Build a C-extension library wheel artifacts"
      uses: ansys/actions/build-ci-library@v6.0
