Subject [jira] Created: (CONFIGURATION-370) Customizing the Properties Reader
Date Tue, 10 Mar 2009 23:28:50 GMT
Customizing the Properties Reader
---------------------------------

                 Key: CONFIGURATION-370
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-370
             Project: Commons Configuration
          Issue Type: New Feature
    Affects Versions: 1.6
         Environment: Properties File Reader.
            Reporter: Andrew Hughes


Currently Commons Configuration does not offer support to handle non-standard property file
parsing. Inparticular, you can't parse properties where the key has whitespace.

Taken from thread on mailing list:

Howdy,

We've got legacy/shared property files for our config (i.e. can't change the property files
to solve this). We're trying to use commons-config but it has difficulty dealing with our
properties files as the key's contain whitespace.

Any help on how I can resolve this would be most welcomed :)

Example Property:

Welcome Message=Hello World

Cheers.

The current code does not seem to support whitespace in property keys.

PropertiesConfiguration uses PropertiesConfigurationLayout.load() for loading and parsing
configuration files, which in turn delegates to the inner class PropertiesConfiguration.PropertiesReader.
This class interprets all whitespace as end markers of the property key.

It is probably not trivial to inject your own reader for properties files. Maybe you can create
a custom layout class derived from PropertiesConfigurationLayout that overrides the load()
method. You would have to override PropertiesConfiguration.createLayout() to activate your
new layout class.

Given these problems it would probably be a good idea if the library offered better support
for customizing the properties reader. If you consider this helpful, feel free to open an
enhancement ticket in Jira [1].
