Augmented python configparser

Project description


Python PyPi License Black

`jconfigparser` is an extension of the `python` `configparser` standard module which adds the following features inspired by [`TOML`](
  • Section name depth with dot notation: [a.b]
  • Values on right hand side can be everything that is understood by JSON.
  • Values that appear twice or more often are stored as a list, see example output below (this behavior is configurable).


Say we have the following configuration file in test.jconf:

format:                        aims

xc:                            pbesol
charge_mix_param:              0.3
sc_accuracy_rho:               1e-6

output: band  0     0     0     0.00  0.25  0.25  50   Gamma  Delta
output: band  0.00  0.25  0.25  0     0.5   0.5   50   Delta  X

port:                          null

default:                       light

This file can be parsed with

import jconfigparser as jc

config = jc.Config('test.jconf')

config will be a modified dict that hold the information like

    "atoms": {"file": "", "format": "aims"},
    "calculator": {
        "aims": {
            "xc": "pbesol",
            "charge_mix_param": 0.3,
            "sc_accuracy_rho": 1e-06,
            "output": [
                "band  0     0     0     0.00  0.25  0.25  50   Gamma  Delta",
                "band  0.00  0.25  0.25  0     0.5   0.5   50   Delta  X",
        "socketio": {"port": None},
    "basissets": {"aims": {"default": "light"}},

Furthermore, config supports

  • Attribute access, e.g., config.atoms.file
  • Write itself: config.write("new.jconf")
