Input values into json file — input

Inputs values into json file by locating the label and key within the json file. Preserves comments (!) if present. NOTE: this does not use a json parser so if there are json formatting errors this function will not pick them up.

Usage

input_json(file, label, key, value, out_file = NULL)

Arguments

file: filepath; to json file which you wish to edit
label: string; which corresponds to section where the key is located
key: string; name of key in which to input the value
value: string; to be input into the key/value pair. Note boolean values must be input as 'true'/'false' as per the json format
out_file: filepath; to write the output json file (optional); defaults to overwriting file if not specified
