Installation

Required libraries:

• NumPy

• deprecation

Optional libraries (all available on PyPI, some available on conda or conda-forge):

• SyllabiPy

• NLTK

• PyLZSS

• paq

To install Abydos (master) from Github source:

git clone https://github.com/chrislit/abydos.git --recursive
cd abydos
python setup install

If your default python command calls Python 2.7 but you want to install for Python 3, you may instead need to call:

python3 setup install

To install Abydos (latest release) from PyPI using pip:

pip install abydos

To install from conda-forge:

conda install abydos

It should run on Python 3.5-3.8.

Testing & Contributing

To run the whole test-suite just call tox:

tox

The tox setup has the following environments: black, py37, doctest, regression, fuzz, pylint, pydocstyle, flake8, doc8, docs, sloccount, badges, & build. So if you only want to generate documentation (in HTML, EPUB, & PDF formats), just call:

tox -e docs

In order to only run & generate Flake8 reports, call:

tox -e flake8

Contributions such as bug reports, PRs, suggestions, desired new features, etc. are welcome through Github Issues & Pull requests.

0.3.6 (2018-11-17) classy carl

doi:10.5281/zenodo.1490537

Changes:

• Most functions were encapsulated into classes.

doi:10.5281/zenodo.1463204

Changes:

• Refactored library and tests into smaller modules
