Description

This package provides a light framework that can be used to automatically generate exceptions documentation marked up in reStructuredText.

The exdoc module details how to register exceptions, how to traced them and how to generate their documentation

Interpreter

The package has been developed and tested with Python 2.7, 3.5, 3.6 and 3.7 under Linux (Debian, Ubuntu), Apple macOS and Microsoft Windows

Installing

$ pip install pexdoc

Contributing

  1. Abide by the adopted code of conduct

  2. Fork the repository from GitHub and then clone personal copy [1]:

    $ github_user=myname
    $ git clone --recurse-submodules \
          https://github.com/"${github_user}"/pexdoc.git
    Cloning into 'pexdoc'...
    ...
    $ cd pexdoc || exit 1
    $ export PEXDOC_DIR=${PWD}
    $
    
  3. The package uses two sub-modules: a set of custom Pylint plugins to help with some areas of code quality and consistency (under the pylint_plugins directory), and a lightweight package management framework (under the pypkg directory). Additionally, the pre-commit framework is used to perform various pre-commit code quality and consistency checks. To enable the pre-commit hooks:

    $ cd "${PEXDOC_DIR}" || exit 1
    $ pre-commit install
    pre-commit installed at .../pexdoc/.git/hooks/pre-commit
    $
    
  4. Ensure that the Python interpreter can find the package modules (update the $PYTHONPATH environment variable, or use sys.paths(), etc.)

    $ export PYTHONPATH=${PYTHONPATH}:${PEXDOC_DIR}
    $
    
  5. Install the dependencies (if needed, done automatically by pip):

  6. Implement a new feature or fix a bug

  7. Write a unit test which shows that the contributed code works as expected. Run the package tests to ensure that the bug fix or new feature does not have adverse side effects. If possible achieve 100% code and branch coverage of the contribution. Thorough package validation can be done via Tox and Pytest:

    $ PKG_NAME=pexdoc tox
    GLOB sdist-make: .../pexdoc/setup.py
    py27-pkg create: .../pexdoc/.tox/py27
    py27-pkg installdeps: -r.../pexdoc/requirements/tests_py27.pip, -r.../pexdoc/requirements/docs_py27.pip
    ...
      py27-pkg: commands succeeded
      py35-pkg: commands succeeded
      py36-pkg: commands succeeded
      py37-pkg: commands succeeded
      congratulations :)
    $
    

    Setuptools can also be used (Tox is configured as its virtual environment manager):

    $ PKG_NAME=pexdoc python setup.py tests
    running tests
    running egg_info
    writing pexdoc.egg-info/PKG-INFO
    writing dependency_links to pexdoc.egg-info/dependency_links.txt
    writing requirements to pexdoc.egg-info/requires.txt
    ...
      py27-pkg: commands succeeded
      py35-pkg: commands succeeded
      py36-pkg: commands succeeded
      py37-pkg: commands succeeded
      congratulations :)
    $
    

    Tox (or Setuptools via Tox) runs with the following default environments: py27-pkg, py35-pkg, py36-pkg and py37-pkg [3]. These use the 2.7, 3.5, 3.6 and 3.7 interpreters, respectively, to test all code in the documentation (both in Sphinx *.rst source files and in docstrings), run all unit tests, measure test coverage and re-build the exceptions documentation. To pass arguments to Pytest (the test runner) use a double dash (--) after all the Tox arguments, for example:

    $ PKG_NAME=pexdoc tox -e py27-pkg -- -n 4
    GLOB sdist-make: .../pexdoc/setup.py
    py27-pkg inst-nodeps: .../pexdoc/.tox/.tmp/package/1/pexdoc-1.1.2.zip
    ...
      py27-pkg: commands succeeded
      congratulations :)
    $
    

    Or use the -a Setuptools optional argument followed by a quoted string with the arguments for Pytest. For example:

    $ PKG_NAME=pexdoc python setup.py tests -a "-e py27-pkg -- -n 4"
    running tests
    ...
      py27-pkg: commands succeeded
      congratulations :)
    $
    

    There are other convenience environments defined for Tox [3]:

    • py27-repl, py35-repl, py36-repl and py37-repl run the Python 2.7, 3.5, 3.6 and 3.7 REPL, respectively, in the appropriate virtual environment. The pexdoc package is pip-installed by Tox when the environments are created. Arguments to the interpreter can be passed in the command line after a double dash (--).

    • py27-test, py35-test, py36-test and py37-test run Pytest using the Python 2.7, 3.5, 3.6 and 3.7 interpreter, respectively, in the appropriate virtual environment. Arguments to pytest can be passed in the command line after a double dash (--) , for example:

      $ PKG_NAME=pexdoc tox -e py27-test -- -x test_pexdoc.py
      GLOB sdist-make: .../pexdoc/setup.py
      py27-pkg inst-nodeps: .../pexdoc/.tox/.tmp/package/1/pexdoc-1.1.2.zip
      ...
        py27-pkg: commands succeeded
        congratulations :)
      $
      
    • py27-test, py35-test, py36-test and py37-test test code and branch coverage using the 2.7, 3.5, 3.6 and 3.7 interpreter, respectively, in the appropriate virtual environment. Arguments to pytest can be passed in the command line after a double dash (--). The report can be found in ${PEXDOC_DIR}/.tox/py[PV]/usr/share/pe xdoc/tests/htmlcov/index.html where [PV] stands for 2.7, 3.5, 3.6 or 3.7 depending on the interpreter used.

  8. Verify that continuous integration tests pass. The package has continuous integration configured for Linux, Apple macOS and Microsoft Windows (all via Azure DevOps).

  9. Document the new feature or bug fix (if needed). The script ${PEXDOC_DIR}/pypkg/build_docs.py re-builds the whole package documentation (re-generates images, cogs source files, etc.):

    $ "${PEXDOC_DIR}"/pypkg/build_docs.py -h
    usage: build_docs.py [-h] [-d DIRECTORY] [-r]
                         [-n NUM_CPUS] [-t]
    
    Build pexdoc package documentation
    
    optional arguments:
      -h, --help            show this help message and exit
      -d DIRECTORY, --directory DIRECTORY
                            specify source file directory
                            (default ../pexdoc)
      -r, --rebuild         rebuild exceptions documentation.
                            If no module name is given all
                            modules with auto-generated
                            exceptions documentation are
                            rebuilt
      -n NUM_CPUS, --num-cpus NUM_CPUS
                            number of CPUs to use (default: 1)
      -t, --test            diff original and rebuilt file(s)
                            (exit code 0 indicates file(s) are
                            identical, exit code 1 indicates
                            file(s) are different)
