castep_outputs
==============

Parser for CASTEP output files

``castep_outputs`` parses the output files of `castep
<https://www.castep.org/>`__ into a standard form and is able to subsequently
dump the processed data into a standard format.

Install
-------

To install ``castep_outputs`` simply run:

::

   pip install castep_outputs

To check it is installed run:

::

   python -m castep_outputs -h

Dependencies
------------

``castep_outputs`` is designed to have no external dependencies beyond the
standard library, however, it is possible to use either `PyYAML
<https://pypi.org/project/PyYAML/>`__ or `ruamel.yaml
<https://pypi.org/project/ruamel.yaml/>`__ to dump in the YAML format.

Command-line
------------

When run as a commandline tool, it attempts to find all files for the given
seedname, filtered by ``inc`` args (default: all). Explicit files can be passed
using longname arguments. castep_outputs can parse most human-readable castep
outputs including: ``.castep``, ``.param``, ``.cell``, ``.geom``, ``.md``,
``.bands``, ``.hug``, ``.phonon_dos``, ``.efield``, ``.xrd_sf``, ``.elf_fmt``,
``.chdiff_fmt``, ``.pot_fmt``, ``.den_fmt``, ``.elastic``, ``.ts``, ``.magres``.

to run in basic mode:

::

   python -m castep_outputs seedname

Which will attempt to detect all found files and dump a ``.json`` to
stdout, ready for piping.

::

   python -m castep_outputs --inc-castep --inc-param seedname

Will parse only the ``seedname.castep`` and ``seedname.param`` files if
found.

::

   python -m castep_outputs seedname.castep

Will parse the single named file and again dump a ``.json`` to stdout.

::

   python -m castep_outputs --castep seedname.param

Will attempt to parse the file ``seedname.param`` as though it were a
``.castep`` file. While not ordinarily useful it can help with manually renamed
files.

::

   python -m castep_outputs -o my_file.yaml -f yaml seedname.castep

Will parse ``seedname.castep``, dump it to ``my_file.yaml`` in ``yaml`` format
using the ``PyYAML`` engine.

As a module
-----------

``import``\ ing ``castep_outputs`` directly puts all of the parsers directly
into your local namespace.

The simplest method to use ``castep_outputs`` in a tool is to use the
``parse_single`` method which attempts to determine the parser from the file
extension.

::

   import castep_outputs

   my_dict = parse_single('my_file.castep')

If you need a specific parser rather than by extension it is possible to pass
them as the second argument, or call them directly.

::

   import castep_outputs

   my_dict = parse_single('my_file', parse_castep_file)

   with open('my_file', 'r', encoding='utf-8') as inp:
       my_dict = parse_castep_file(inp)

It is recommended that you use ``parse_single`` as it uses special file-handling
to give better diagnostics if it fails. It is possible to enable more detailed
logging via the `logging
<https://docs.python.org/3/library/logging.html#logging.basicConfig>`_ module:

::

   import castep_outputs
   import logging

   my_dict = parse_single('my_file', loglevel=logging.INFO)

The available parsing functions are:

-  ``parse_castep_file``
-  ``parse_cell_param_file``
-  ``parse_param_file``
-  ``parse_cell_file``
-  ``parse_md_geom_file``
-  ``parse_md_file``
-  ``parse_geom_file``
-  ``parse_bands_file``
-  ``parse_hug_file``
-  ``parse_phonon_dos_file``
-  ``parse_efield_file``
-  ``parse_xrd_sf_file``
-  ``parse_elf_fmt_file``
-  ``parse_chdiff_fmt_file``
-  ``parse_pot_fmt_file``
-  ``parse_den_fmt_file``
-  ``parse_elastic_file``
-  ``parse_ts_file``
-  ``parse_tddft_file``
-  ``parse_magres_file``

Which return processed ``list``\ s of ``dict``\ s of data ready for use
in other applications.
