javaproperties
provides support for reading & writing |properties|_ (both
the simple line-oriented format and XML) with a simple API based on the
json
module — though, for recovering Java addicts, it also includes a
Properties
class intended to match the behavior of |propclass|_ as much as
is Pythonically possible.
Previous versions of javaproperties
included command-line programs for
basic manipulation of .properties
files. As of version 0.4.0, these
programs have been split off into a separate package, |clipkg|_.
javaproperties
requires Python 3.8 or higher. Just use pip <https://pip.pypa.io>
_ for Python 3 (You have pip, right?) to install it::
python3 -m pip install javaproperties
Dump some keys & values (output order not guaranteed):
properties = {"key": "value", "host:port": "127.0.0.1:80", "snowman": "☃", "goat": "🐐"} print(javaproperties.dumps(properties)) #Mon Sep 26 14:57:44 EDT 2016 key=value goat=\ud83d\udc10 host:port=127.0.0.1:80 snowman=\u2603
Load some keys & values:
javaproperties.loads(''' ... #Mon Sep 26 14:57:44 EDT 2016 ... key = value ... goat: \ud83d\udc10 ... host\:port=127.0.0.1:80 ... #foo = bar ... snowman ☃ ... ''') {'goat': '🐐', 'host:port': '127.0.0.1:80', 'key': 'value', 'snowman': '☃'}
Dump some properties to a file and read them back in again:
with open('example.properties', 'w', encoding='latin-1') as fp: ... javaproperties.dump(properties, fp) ... with open('example.properties', 'r', encoding='latin-1') as fp: ... javaproperties.load(fp) ... {'goat': '🐐', 'host:port': '127.0.0.1:80', 'key': 'value', 'snowman': '☃'}
Sort the properties you're dumping:
print(javaproperties.dumps(properties, sort_keys=True)) #Mon Sep 26 14:57:44 EDT 2016 goat=\ud83d\udc10 host:port=127.0.0.1:80 key=value snowman=\u2603
Turn off the timestamp:
print(javaproperties.dumps(properties, timestamp=None)) key=value goat=\ud83d\udc10 host:port=127.0.0.1:80 snowman=\u2603
Use your own timestamp (automatically converted to local time):
print(javaproperties.dumps(properties, timestamp=1234567890)) #Fri Feb 13 18:31:30 EST 2009 key=value goat=\ud83d\udc10 host:port=127.0.0.1:80 snowman=\u2603
Dump as XML:
value 🐐 127.0.0.1:80 ☃print(javaproperties.dumps_xml(properties))
New in v0.6.0: Dump Unicode characters as-is instead of escaping them:
print(javaproperties.dumps(properties, ensure_ascii=False)) #Tue Feb 25 19:13:27 EST 2020 key=value goat=🐐 host:port=127.0.0.1:80 snowman=☃
