WOW.

This rule will be NICE to play with.  I haven't checked yet, but I'm
assuming this rule isn't part of Digester (heck, Hubert, that's why he
said "custom").  If so, maybe it's something that can be added to the
core, or (if it needs to be customized per use) even just in a
Digester example app.

Re: [OT] Complicated Digester Rules [ RE: Common Chain 1.0 and Struts Chain ]

[Craig McClanahan]

Here's an informal description of what that ruleset is about. 
Informally, we want to be able to parse things like:

  
...

  ...
  

  
  

  
  ...

...
  

With a few extra wrinkles:

* I want to be able to substitute the names of the elements that have
  default names "catalog", "chain", and "name" above.  This is done by
  instantiating a ConfigRuleSet and setting the corresponding properties
  before using that RuleSet instance to set up a ConfigParser.

* I want to be able to change the names of some attributes that the
  configuration rules look for, such as "class" (for the FQCN of a chain
  or command instance), customized the same way.

* I want to be able to define "alias" elements for commands that are used
  a lot, so I don't have to specify the FQCN on every one of them.  For example,
  the following element (from the unit tests):



  means I can use the following:



  instead of the more verbose:



  every time I want to use that particular command.

I'm particularly pround of that custom Digester rule :-), but it is
definitely an intricate one, because it calculates and adds some
additional rules during the parse, instead of before.

Re: Common Chain 1.0 and Struts Chain

[Julian]

Joe,

Thanks a lot.  I will plan on implementing the chain
after a bit more due dilligence.  btw, I agree on
making a seperate jar for the set of commands which
provide legacy support.  Thanks.

Cheers Niall

The reason I downloaded the chain again, because I want to study
the chain implementation. I think the Chain would make a good 
invocation AOP/IoC element, if you want to inject some complicated
rules driven advice ... but not this thread

I also wanted looked close at the Digester rules in the Chain 
implementation. I am not if I follow everything in it.

Does any one have a HOWTO and GUIDE into writing Digester rules,
config set and possibly regexp rules?

I have written some Digester stuff and now I want to refactor it
because there is a lot of commonality with the XML grammar (DTD) 
and the stuff I have now is becoming terser every version.

The struts-chain was working just fine against pre-1.0 releases of 
Struts Chain.  If you're interested, there's no reason to wait.  It 
will be longer before you can download a nightly build of Struts 
which uses the Chain request processor, but work on that was mostly 
waiting for the 1.0 release (and for time, which unfortunately I've 
had a short supply of, and this time of year, it will continue that 
way.)

I have a few pending questions on the dev list that I may need to 
re-raise about a few implementation details, but now that 1.0 is 
fully released, I do hope to begin making changes to the core code 
base to use commons-chain and the Composable Request Processor.  I 
don't see the point of just merging struts-chain into the 'core' 
project and cutting a release; rather, we'll want to obsolete the 
PlugIn which configures the command catalogs in struts-chain in favor 
of direct support in the ActionServlet.  I am also inclined to 
package the set of commands which provide legacy Struts support as a 
separate JAR, rather than pushing a few dozen classes into the core 
which in some sense are legacy bound.  (Whether there's consensus on 
that is one of the questions to re-raise on the dev list.)

I've been using struts-chain in a production project for close to a 
year now (including original development time).  We flushed a few 
bugs out along the way, but it's fundamentally stable with Struts 
1.2.x.
