Package: pmisc
DescriptionThis module contains miscellaneous utility functions that can be applied in a
variety of circumstances; there are context managers, membership functions
(test if an argument is of a given type), numerical functions, string
functions and functions to aid in the unit testing of modulesPytestis the supported test runnerInterpreterThe package has been developed and tested with Python 3.5, 3.6, 3.7 and 3.8

...$cdpmisc||exit1$exportPMISC_DIR=${PWD}$The package uses two sub-modules: a set of custom Pylint plugins to help with
some areas of code quality and consistency (under thepylint_pluginsdirectory), and a lightweight package management framework (under thepypkgdirectory). Additionally, thepre-commit frameworkis used to perform various pre-commit code
quality and consistency checks. To enable the pre-commit hooks:$cd"${PMISC_DIR}"||exit1$pre-commitinstallpre-commit installed at .../pmisc/.git/hooks/pre-commit$Ensure that the Python interpreter can find the package modules

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=pmisctoxGLOB sdist-make: .../pmisc/setup.py

  congratulations :)$Tox (or Setuptools via Tox) runs with the following default environments:py35-pkg,py36-pkg,py37-pkgandpy38-pkg[3]. These use
the 3.5, 3.6, 3.7 and 3.8 interpreters, respectively, to test all code in
the documentation (both in Sphinx*.rstsource files and in
docstrings), run all unit tests, measure test coverage and re-build the
exceptions documentation. To pass arguments to Pytest (the test runner) use
a double dash (--) after all the Tox arguments, for example:$PKG_NAME=pmisctox-epy35-pkg---n4GLOB sdist-make: .../pmisc/setup.py
py35-pkg inst-nodeps: .../pmisc/.tox/.tmp/package/1/pmisc-1.5.12.zip

string with the arguments for Pytest. For example:$PKG_NAME=pmiscpythonsetup.pytests-a"-e py35-pkg -- -n 4"running tests
