PyBuilder Archetype Base Plugin

This plugin generates a base common structure with no major dependecies. The main idea is to get an skeleton that can be used for any kind of Python module. It modifies PyBuilder structure logic lightly, removing some packages making it less Java-like.

In the following diagram there is every directory and file created during create_archetype_base:

bin
docs
src
└── package_name
    ├── config  # For any kind of configuration files or constants
    |   ├── logger
    |   |   └── logger.yml
    |   ├── __init__.py
    |   ├── constants.py
    |   └── messages.py
    ├── core  # Logic of the project itself
    |   └── __init__.py
    ├── errors  # For every custom exception made
    |   ├── core  # Make as many scripts as packages in core (i.e. processing.py for core.processing)
    |   |   └── __init__.py
    |   └── __init__.py
    ├── utils  # For any kind of util used in the project
    |   ├── logging
    |   |   ├── __init__.py
    |   |   └── handlers.yml  # For custom logging handles (i.e. database logging)

There are other PyBuilder plugins that depend on pybuilder_archetype_base that include other more specific packages. These plugins are:

• pybuilder_archetype_api: For projects focused on web services
• (WIP) pybuilder_archetype_db: For projects using databases

How to use pybuilder_archetype_base

NOTICE: This plugin only works on Windows due to its dependency with pybuilder_pycharm_workspace PyBuilder plugin. Using this plugin in other OS shall not work properly. Multi-platform support soon.

Add plugin dependencies to your build.py (it requires pybuilder_pycharm_workspace to work properly):

use_plugin('pypi:pybuilder_archetype_base')
use_plugin('pypi:pybuilder_pycharm_workspace')

Configure the plugin within your init function:

@init
def initialise(project):
    project.set_property('project_base_path', project_path)
    project.set_property('pycharm_workspace_project_path', project_path)

This will tell the plugin which is the project location in the filesystem. project_base_path property value should be always the same. It is needed to inform pycharm_workspace_project_path too in order to get pybuilder_pycharm_workspace working.

Launch the task with:

(venv) C:\Users\foo\PycharmProjects\bar> pyb create_archetype_base

build.py file recommended

This plugin doesn't include a build.py file due to there should be already one at the moment of the execution of pyb command. The following template can be used along this plugin. Modify as desired.

from pathlib import Path

from pybuilder.core import use_plugin, init, Author, before


use_plugin('python.core')
use_plugin('python.distutils')
use_plugin('python.flake8')
use_plugin('python.unittest')

use_plugin('pypi:pybuilder_pycharm_workspace')
use_plugin('pypi:pybuilder_archetype_base')

project_path = Path(__file__).resolve().parent

name = project_path.name
authors = [Author("foo", 'bar')]
license = "Apache License, Version 2.0"
version = '1.0.0'


@init
def initialise(project):
    project.depends_on_requirements('requirements.txt')

    project.set_property('dir_source_main_python', 'src')

    project.set_property('dir_source_unittest_python', 'tests')
    project.set_property('unittest_module_glob', 'test_*')

    project.set_property('project_base_path', project_path)
    project.set_property('pycharm_workspace_project_path', project_path)


@init(environments='develop')
def initialise_dev(project):
    project.version = f'{project.version}.dev'
    project.set_property('flake8_verbose_output', True)


@init(environments='production')
def initialise_pro(project):
    project.set_property('flake8_break_build', True)
    project.set_property('flake8_include_test_sources', True)


@before('prepare')
def pack_files(project):
    """
    Includes non-Python files in the build.

    :param pybuilder.core.Project project: PyBuilder project instance
    :return: None
    """
    package_path = list(Path(project.get_property('dir_source_main_python')).glob('*'))[0]
    resources_paths = sorted(package_path.glob('**'))[1:]
    project.package_data.update(
        { package_path.name: [str((path.relative_to(package_path) / '*').as_posix()) for path in resources_paths] })

Take note of build.py example on pybuilder_pycharm_workspace plugin README to cover its needs too.
