Tasks

The nmk-python plugin defines the tasks described below.

Setup tasks

All tasks in this chapter are dependencies of the base setup task.

py.version – Python version stamping

This task creates/updates the ${pythonVersionStamp} stamp file, only when ${gitVersion} has changed. This allows incremental build depending on python version change (i.e. trigger rebuild if only version changed).

Property	Value/description
builder	nmk_python.version.PythonVersionRefresh
input	${gitVersionStamp} file
output	${pythonVersionStamp} file

The builder is called with the following parameters mapping:

Name	Value
version	${pythonVersion}

Note

Behavior changed in version 1.7.0
In former versions, this task was only triggered if ${pythonSrcFiles} were found.

py.project – Python project file generation

This task generates the ${pythonProjectFile} project file.

Property	Value/description
builder	nmk_base.common.TomlFileBuilder
input	${pythonProjectFileFragments} files
output	${pythonProjectFile} file

The builder is called with the following parameters mapping:

Name	Value
fragment_files	${pythonProjectFileFragments}
items	${pythonProjectFileItems}
plugin_name	“nmk-python”

Note

Behavior changed in version 1.7.0
In former versions, this task was only triggered if ${pythonSrcFiles} were found.

Build tasks

All tasks in this chapter are dependencies of the base build task.

py.format – Python code format

This task calls ruff format command to format python code of this project.

Property	Value/description
builder	nmk_python.ruff.RuffBuilder
input	${pythonSrcFiles} + ${pythonProjectFile} files
output	${pythonRuffFormatStamp} file
if	${pythonSrcFiles} are found

The builder is called with the following parameters mapping:

Name	Value
src_folders	${pythonSrcFolders}
command	format ${pythonRuffCommonExtraArgs} ${pythonRuffFormatExtraArgs} Changed in version 1.2 – Previous value was "format"

py.fix – Python code fix

This task calls ruff check --fix-only command to fix python code of this project.

See ${pythonAutoFixRules} config item to define rules categories to auto-fix.

Property	Value/description
builder	nmk_python.ruff.RuffBuilder
input	${pythonSrcFiles} + ${pythonProjectFile} files
output	${pythonRuffFixStamp} file
if	${pythonSrcFiles} are found

The builder is called with the following parameters mapping:

Name	Value
src_folders	${pythonSrcFolders}
command	check –fix-only –select ${pythonAutoFixJoinedRules} ${pythonRuffCommonExtraArgs} ${pythonRuffFixExtraArgs}

Added in version 1.2

py.analyze – Python code analysis

This task calls ruff check command to analyze python code of this project.

Property	Value/description
builder	nmk_python.ruff.RuffBuilder
input	${pythonSrcFiles} + ${pythonProjectFile} files
output	${pythonRuffCheckStamp} file
if	${pythonSrcFiles} are found

The builder is called with the following parameters mapping:

Name	Value
src_folders	${pythonSrcFolders}
command	check ${pythonRuffCommonExtraArgs} ${pythonRuffCheckExtraArgs} Changed in version 1.2 – Previous value was "check"

py.editable – Python project install in editable mode

This task installs the project in editable mode in the venv.

Property	Value/description
builder	nmk_python.build.EditableBuilder
input	${pythonProjectFile} file
output	${pythonEditableStamp} file
if	${pythonSrcFiles} are found

py.deps – Generate Python dependencies metadata

This task generates the ${pythonDepsMetadata} metadata json file, containing all current project dependencies versions (indexed by name).

Dependencies are splitted between internal and external ones:

• internal dependencies are all ones matching with any pattern defined in ${pythonLocalDepsPatterns} (if any)

• external dependencies are all the other ones

Property	Value/description
builder	nmk_python.build.DepsMetadataBuilder
input	${pythonProjectFile} file
output	${pythonDepsMetadata} file
if	${pythonSrcFiles} are found

The builder is called with the following parameters mapping:

Name	Value
root_name	${pythonPackage}
local_deps	${pythonLocalDepsPatterns}

Added in version 1.8.0

Tests tasks

All tasks in this chapter are dependencies of the base tests task.

py.tests – Run Python tests

This task calls pytest command to execute python tests.

Property	Value/description
builder	nmk_python.tests.PytestBuilder
if	${pythonTestSrcFiles} are found

The builder is called with the following parameters mapping:

Name	Value
pytest_args	${pytestExtraArgs}

Package tasks

All tasks in this chapter are dependencies of the base package task.

py.build – Build Python wheel

This task use the python build module to handle the wheel build.

Property	Value/description
builder	nmk_python.build.PackageBuilder
input	${pythonSrcFiles} + ${pythonProjectFile} files
output	${pythonWheel} file
if	${pythonSrcFiles} are found

The builder is called with the following parameters mapping:

Name	Value
project_file	${pythonProjectFile}
version_file	${pythonVersionStamp}
source_dirs	${pythonSrcFolders}
artifacts_dir	${pythonArtifacts}
build_dir	${pythonBuildDir}
extra_resources	${pythonExtraResources}

Install tasks

All tasks in this chapter are dependencies of the base install task.

py.install – Install Python wheel

This task installs the built python wheel in the project venv.

Property	Value/description
builder	nmk_python.build.Installer
input	${pythonWheel} file
output	${venvState}
if	${pythonSrcFiles} are found

The builder is called with the following parameters mapping:

Name	Value
name	${pythonPackage}
wheel	${pythonWheel} Changed in version 1.7.0
to_remove	${pythonEditableStamp}

The builder also removes the ${pythonEditableStamp} stamp file, to force installing the project in editable mode again on the next build.

Clean tasks

All tasks in this chapter are dependencies of the base clean task.

py.uninstall – Uninstall Python wheel and local dependencies

This task uninstalls the built python wheel and its local dependencies from the project venv.
