Python tools to handle CP2K output files

Project description

cp2k-output-tools

Modular CP2K output file parsers, mostly in the form of regular expressions.

Requirements

Python 3.6+
regex 2020+

For development: https://poetry.eustace.io/ https://pytest.org/

Usage

There is a simple command-line interface cp2kparse:

$ cp2kparse --help
usage: cp2kparse [-h] [-y] [-k <path>] [<file>]

Parse the CP2K output file and return a JSON

positional arguments:
  <file>                CP2K output file, stdin if not specified

optional arguments:
  -h, --help            show this help message and exit
  -y, --yaml            output yaml instead of json
  -k <path>, --key <path>
                        Path, ex.: 'energies/total force_eval'
