openprops

OpenProps is a tiny Java library which reads and writes .properties files using the same code as java.util.Properties from the OpenJDK, but enhanced so that it preserves the order of entries within the file, and it also preserves comments in the file. This means that a Properties editor or a file converter written to use OpenProps won't have to lose comments or mess up the order of entries. By using OpenJDK code, OpenProps should handle all the old corner-cases in exactly the same way Java does. The handling of whitespace and comments is tested by a number of JUnit tests. But please let me know if you find a bug! Note the following differences from java.util.Properties: 1. preserves comments and the order of entries in the file 2. storeToXml doesn't use the Sun DTD (or any DTD) because it adds attributes for comments. 3. equals() and hashCode() won't work the same way as with java.util.Properties, because they are no longer inherited from Hashtable. All you get is identity equality/hashcode. Also note that any header comment in the .properties file will be interpreted as a comment attached to the first message.
