postgkyl 1.7.4.dev1

Postgkyl

This is the Postgkyl project. It is both Python library and command-line tool
designed to provide unified access to Gkeyll data together with a broad variety
of analytical and visualization tools.
Documentation
Full documentation of the Gkeyll project is available at
ReadTheDocs.
Dependencies and Installation
Postgkyl requires the following packages:

click
matplotlib
msgpack
numpy
scipy
sympy
tables

Note that Posgkyl currently does not work with NumPy >= 2.0; the update is in
the works. In addition, there are two optional dependencies:

adios2
pytest

ADIOS 2 is required for reading Gkeyll 2 bp output files and it is not needed
when working only with gkylzero. pytest
is required only for developers.
Setting up virtual environment (recommended)
We strongly recommend creating a virtual Python environment for everybody
working with more than one Python project (this includes even using both
Postgkyl and Sphinx). The two recommended options are
venv and
mamba.
With venv, one can create the virtual environment with:
python -m venv /path/to/new/virtual/environments/pgkyl

then activate it with:
| bash/zsh | source <venv>/bin/activate |
| fish | source <venv>/bin/activate.fish |
| csh/tcsh | source <venv>/bin/activate.csh |
and deactivate with:
deactivate

With mamba, one can create the virtual environment with:
mamba create -n pgkyl

then activate with:
mamba activate pgkyl

and deactivate with:
mamba deactivate

Note that with mamba, one can also use the provided environment.yml file,
which also includes dependency specifications:
mamba env create -f environment.yml

Installing Postgkyl
The Postgkyl itself is installed with pip.[^1] Developers and uses who want to
have the most up-to-date version should install Postgkyl from the source code:
git clone git@github.com:ammarhakim/postgkyl.git
cd postgkyl
pip install -e .[adios,test]

Alternatively, Postgkyl can be installed directly from PyPI:
pip install -e postgkyl[adios,test]

Note that ADIOS2 is not available on PyPI for Mac OSX; therefore, Mac users who
want to use it need to install the dependency from elsewhere, for example, using
the above-mentioned mamba and then do not use the adios tag with pip.
Testing
Postgkyl utilizes pytest for testing. The tests can
be called manually from the root Postgkyl directory simply by using:
pytest [-v]

Postgkyl was used previously through PYTHONPATH, we strongly recommend
removing the path to the Postgkyl repository from the variable.
