Development

Dependencies and packaging are managed by Poetry.

Install the virtual environment and enter it with

$ poetry install
$ poetry shell

Testing and code style

To execute data tests, run

$ pytest

To run python style autoformaters (isort, black), run

$ make autoformat

Localization

Apart from English, this package has partial translations to German, Spanish, and Esperanto languages.

To test duden in other languages, set the LANG environment variable before running duden like so:

LANG=de_DE.UTF-8 duden Kragen
LANG=es_ES.UTF-8 duden Kragen
LANG=eo_EO.UTF-8 duden Kragen

The translations are located in the duden/locale/ directory as the *.po and duden.pot files. The duden.pot file defines all translatable strings in series of text blocks formatted like this:

#: main.py:82
msgid "Commonness:"
msgstr ""

while the individual language files provides translations to the strings identified by msgid like this:

#: main.py:82
msgid "Commonness:"
msgstr "Häufigkeit:"

Note that the commented lines like #: main.py:82 do not have any functional meaning, and can get out of sync.

Publishing

To build and publish the package to (test) PyPI, you can use one of these shortcut commands:

$ make pypi-publish-test
$ make pypi-publish

(these also take care of building the localization files before calling poetry publish)

Poetry configuration for PyPI and Test PyPI credentials are well covered in this SO answer.

Including localization data in the package

In order for the localization data to be included in the resulting python package, the *.po files must be compiled using the

$ make localization

command before building the package with poetry.

Supported versions of Python

Python 3.4+
