Graphical user interface program for structure refinements to atomic
pair distribution function.

For users who do not have the expertise or necessity for command
line analysis, PDFgui is a convenient and easy to use graphical front
end for the PDFfit2 refinement program. It is capable of full-profile
fitting of the atomic pair distribution function (PDF) derived from x-ray
or neutron diffraction data and comes with built in graphical and structure
visualization capabilities.

PDFgui is a friendly interface to the PDFfit2 refinement engine, with many
powerful extensions.  To get started, please open the manual from the
help menu and follow the tutorial instructions. A detailed description
is available in `this paper <http://dx.doi.org/10.1088/0953-8984/19/33/335219>`_.

For more information about diffpy.pdfgui, please consult our
`online documentation <https://diffpy.github.io/diffpy.pdfgui>`_.

If you use diffpy.pdfgui in a scientific publication, we would like you to
cite this package as

        J Bloch, Th Proffen and S J L Billinge, PDFfit2 and PDFgui:

Installation
------------

Windows, macOS (non-Arm64), Linux
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The preferred method is to use `Miniconda Python
<https://docs.conda.io/projects/miniconda/en/latest/miniconda-install.html>`_
and install from the "conda-forge" channel of Conda packages.

Add the "conda-forge" channel by running the following command in a terminal: ::

        conda config --add channels conda-forge

Create a new environment named ``diffpy.pdfgui_env`` and install ``diffpy.pdfgui``: ::

        conda create -n diffpy.pdfgui_env diffpy.pdfgui

Activate the environment: ::

        conda activate diffpy.pdfgui_env

Confirm that the installation was successful: ::

        python -c "import diffpy.pdfgui; print(diffpy.pdfgui.__version__)"

macOS (Arm64)
~~~~~~~~~~~~~

Create a new conda environment ``diffpy.pdfgui_env``: ::

        conda create -n diffpy.pdfgui_env python=3.13

Activate the environment: ::

        conda activate diffpy.pdfgui_env

It is necessary to get versions of pdffit2 built for Mac from Python package index (Pypi).  To install
pdffit2 from Pypi using ``pip`` to download and install the latest version from `Python Package Index <https://pypi.python.org>`_: ::

        pip install diffpy.pdffit2

Confirm that the installation was successful: ::

        python -c "import diffpy.pdffit2; print(diffpy.pdffit2.__version__)"

Now we want to install PDFgui and dependencies from conda-forge: ::

        conda install wxpython diffpy.utils matplotlib-base
        conda install diffpy.pdfgui --no-deps


Build from source
~~~~~~~~~~~~~~~~~

For advanced users, obtain the source archive, and in the ``diffpy.pdffit2`` directory, run ::

        conda create -n diffpy.pdffit2_env python=3.13 \
                --file requirements/test.txt \
                --file requirements/conda.txt \
                --file requirements/build.txt

Activate the environment, build the package, and run unit tests by following commands sequentially: ::

        conda activate diffpy.pdffit2_env
        pip install . --no-deps
        pytest

Getting Started
---------------

You may consult our `online documentation <https://diffpy.github.io/diffpy.pdfgui>`_ for tutorials and API references.

Support and Contribute
----------------------

`Diffpy user group <https://groups.google.com/g/diffpy-users>`_ is the discussion forum for general questions and discussions about the use of diffpy.pdfgui. Please join the diffpy.pdfgui users community by joining the Google group. The diffpy.pdfgui project welcomes your expertise and enthusiasm!

If you see a bug or want to request a feature, please `report it as an issue <https://github.com/diffpy/diffpy.pdfgui/issues>`_ and/or `submit a fix as a PR <https://github.com/diffpy/diffpy.pdfgui/pulls>`_. You can also post it to the `Diffpy user group <https://groups.google.com/g/diffpy-users>`_.

Feel free to fork the project and contribute. To install diffpy.pdfgui
in a development mode, with its sources being directly used by Python
rather than copied to a package directory, use the following in the root
directory ::

        pip install -e .

To ensure code quality and to prevent accidental commits into the default branch, please set up the use of our pre-commit
hooks.

1. Install pre-commit in your working environment by running ``conda install pre-commit``.

2. Initialize pre-commit (one time only) ``pre-commit install``.

Thereafter your code will be linted by black and isort and checked against flake8 before you can commit.
If it fails by black or isort, just rerun and it should pass (black and isort will modify the files so should
pass after they are modified). If the flake8 test fails please see the error messages and fix them manually before
trying to commit again.

Improvements and fixes are always appreciated.
