pytoolbox 14.8.2

What the release number stands for ?

I do my best to follow this interesting recommendation : Semantic Versioning 2.0.0

How to install it ?

Install some packages that are not handled by pip:

$ sudo apt install liblzma-dev libxml2-dev libxslt-dev libyaml-dev libz-dev
$ sudo apt install ffmpeg git-core python3-dev python3-gi python3-pip screen

If planning to use the imaging extra, especially the exif classes, then you’ll have to install:

$ sudo apt install libcairo2 libcairo2-dev libexiv2-dev libgexiv2-dev libgirepository1.0-dev

The gir1.2-gexiv2-0.10 should also be installed, maybe its already the case.

You may find useful to read PyGObject’s documentation.

If planning to use the vision feature, then you have to install some requirements for dlib:

$ sudo apt install build-essential cmake pkg-config

See https://learnopencv.com/install-dlib-on-ubuntu/ for an up-to-date procedure.

Make sure that pip is up-to-date (PIPception):

$ source /some/python3/venv/bin/active
$ pip install --upgrade pip setuptools wheel

Then, you only need to run setup.py:

$ source /some/python3/venv/bin/activate
$ pip install .

How to enable features/modules ?

Example:

$ python setup.py install --help

Common commands: (see '--help-commands' for more)

  setup.py build      will build the package underneath 'build/'
  setup.py install    will install the package

Global options:
  --verbose (-v)  run verbosely (default)
  --quiet (-q)    run quietly (turns verbosity off)
  --dry-run (-n)  don't actually do anything
  --help (-h)     show detailed help message
  --no-user-cfg   ignore pydistutils.cfg in your home directory

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help


$ python setup.py install --extra-smpte2022

Another way to do this, with pip:

$ pip install -e .[django,flask,mongo,smpte2022]

How to check coverage ?

$ source /some/python3/venv/bin/activate
$ pip install -e .[all,test]
$ flake8 pytoolbox
$ pytest
$ xdg-open htmlcov/index.html

Remarks:

• All Django related modules are excluded from tests!

• However I am using them with Django 1.8 up to 3.1.0.

How to use it ?

Here is an example hello.py using the cmd function provided by pytoolbox:

$ from pytoolbox.subprocess import cmd
$ print(cmd('echo Hello World!')['stdout'])

How to generate documentation ?

The documentation is generated by Sphinx. In fact most of this documentation is extracted from the docstrings of the code.

Here is the procedure:

$ source /some/python3/venv/bin/activate
$ pip install -e .[docs]
$ xdg-open docs/build/html/index.html

How to add it to dependencies of my own project ?

Here is an example setup.py for a project called my-cool-project:

  from setuptools import setup

  setup(
name='my-cool-project',
            version='0.8',
            author='Firstname Lastname',
            author_email='author@something.com',
            install_requires=['...', 'pytoolbox>=14<15', '...'],
            tests_require=['...', 'pytest', '...'],
            license='GPLv3',
            url='https://github.com/nickname/my-cool-project',
            packages=['my_cool_project'])

See pip vcs support to get further details about this.

You also need to install git-core, but it is probably already the case, at least on your development computer ;-)
