Library to read Java style properties files. I don’t particularly like properties files but working with them in Java is very easy. I recently had to support reading Java properties files using Python.
This project is based on Benjamins Brent fork of pyjavaproperties.
The libraries main features are:
Reads properties files.
You can add new properties.
You can save properties to file.
It interprets variables in curly braces {} and dollar curly braces ${}.
Caveats
The library does not interpret unicode characters correctly. If you include charactes like u4500 it will interpret it as , letter y and the number 4500.
Installation
Requires Python 3.3 or better.
$ pip install pyjavapropsUsage
Loading Java properties
filename = os.path.join(TEST_DATA_FOLDER, 'iso-8859-1.properties')
iso_8859_1_properties = JavaProperties()
with open(filename, encoding='iso-8859-1') as property_file:
iso_8859_1_properties.load(property_file)
name = iso_8859_1_properties['name']Saving Java properties to file
filename = os.path.join(TEST_DATA_FOLDER, 'simple.properties')
simple_java_properties = JavaProperties()
with open(filename) as property_file:
simple_java_properties.load(property_file)
simple_java_properties['country'] = 'Angola'
output_filename = os.path.join(OUTPUT_FOLDER, 'simple_%s.properties' % datetime.now().strftime('%Y%m%d_%H%M'))
with open(output_filename, mode='w') as output:
simple_java_properties.store(output)Exporting to json
output_filename = os.path.join(OUTPUT_FOLDER, 'simple_%s.json' % datetime.now().strftime('%Y%m%d_%H%M'))
export_to_json(output_filename, java_properties)
with open(output_filename) as json_data:
json_properties = json.load(json_data)
print(json_properties['Key10'])Development
