Modular CP2K output file parsers, mostly in the form of regular expressions plus other tools to mangle various CP2K output:
cp2kparse... parse CP2K output (for restart & input files look at the cp2k-input-tools project) and allow easy selection of common values.xyz_restart_parser... when restarts occur during an MD you may end up with duplicated frames in the trajectory, this tool filters them (and can easily handle huge files)cp2k_bs2csv... convert a CP2K band structure file to multiple (one-per-set) CSV files for easier plotting. There is also an API available if you need to import bandstructure data into your application.cp2k_pdos... apply a convolution with Gaussians on a regular grid on the CP2K PDOS output and generate a CSV file for further processing or plotting. The same grid is used for all input files with the min/max of the grid automatically determined, but no summation of the different projections is done.

- regex 2021+

- numpy 1.19+
- optional: ruamel.yaml
For development: https://poetry.eustace.io/ https://pytest.org/
There is a simple command-line interface cp2kparse:
$ cp2kparse --help
Usage: cp2kparse [OPTIONS] [FILE|-]
Parse the CP2K output FILE and return a structured output
Options:
-f, --format [json|yaml|highlight]
Output format (json or yaml are structure
formats, highlight shows which lines of the
output have been matched)
--color [auto|always] When to colorize output
-s, --safe-keys generate 'safe' key names (e.g. without
spaces, dashes, ..)
-S, --statistics print some statistics to stderr
-k, --key <PATH> Path, ex.: 'energies/total force_eval'
--help Show this message and exit.
$ cp2kparse calc.out
