[json-lib-user] String to Function

[Chad S. <goo...@gm...>]

I've recently been interested in couchdb and the java library to
access it couchdb4j which uses json-lib to create it's JSON messages,
which is how clients communicate to the server.
Couchdb uses "views" instead of queries.  These views return objects
via a javascript function that the designer defines.  These JavaScript
functions are encoded into JSON messages and sent to the server when
the view is defined.

couchdb4j was unable to create a view because when the javascript
function is added to a JSONObject, json-lib converts that string to a
function (no quotes).  As a result couchdb's JSON decoder receives the
unquoted function where it is expecting a string and it fails.

In the process of figuring this out, I also noticed that
http://www.jsonlint.com/ doesn't consider values of non-quoted
functions valid JSON.  Of course I have no idea who made that site or
what authority they have, but I suppose it's worth mentioning.

I was able to modify the behavior by changing this method so that it
always returns false.  Upon doing this, couchdb4j was able to interact
with couchdb properly.

JSONUtils.java:286

   public static boolean isFunction( Object obj ) {
      //if( obj instanceof String ){
      //   String str = (String) obj;
      //   return str.startsWith( FUNCTION_PREFIX ) &&
FUNCTION_MACTHER.matches( str );
      //}
      //if( obj instanceof JSONFunction ){
      //   return true;
      //}
      return false;
   }


I think it's good for couchdb4j have a non-modified versions of
json-lib as it's dependency, so I'm asking if there is a way in which
the functionality I need (JavaScript functions as quoted strings in
values) can be made available through json-lib.

Thanks,
