javaproperties
provides support for reading & writing Java .properties
files_ (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 Java 8's java.util.Properties
_ 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, javaproperties-cli
_.
javaproperties
requires Python 3.8 or higher. Just use pip 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=ud83dudc10 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=ud83dudc10 host:port=127.0.0.1:80 key=value snowman=u2603
Turn off the timestamp:
>>> print(javaproperties.dumps(properties, timestamp=None)) key=value goat=ud83dudc10 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=ud83dudc10 host:port=127.0.0.1:80 snowman=u2603
Dump as XML:
>>> print(javaproperties.dumps_xml(properties)) <!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"> <properties> <entry key="key">value</entry> <entry key="goat">🐐</entry> <entry key="host:port">127.0.0.1:80</entry> <entry key="snowman">☃</entry> </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=☃
