[rules-dev] Creating DSLR


Hi,
I have small doubt in rules engine. I have downloaded the example and successfully ran those ones.

For generating the drl file I used .brl file, for this I have used guide editor.

Similarly is there any other way to generate the .dslr file using .dsl file?

My requirement is automatically create the DSLR file by using dsl file. Is it possible with drools IDE?

Ahead Together,
Sarath Kumar Daruru

Re: [rules-dev] community skype meetings

What are the limitations of skype re number of users ? I thought it  
was only a few.

Other options are elliminate, bit that means only a few can speak at a  
time, and the voice quality is limited, we we can share notes and a  
whiteboard and host as many people as needed (I have tested the client  
on windows, mac, and Linux and it works, just not as nice as skype).

Re: [rules-dev] Enumeration inconsistency in Guvnor

Hi dave.

The dsl has been corrected just the other day. If decision table still  
does it do you mind creating a jira in the GUVNOR project, and I will  
correct it.

Re: [rules-dev] community skype meetings

Previously skype had a product called Skypecast that enabled many (in theory hundreds) people to join a talk, have a moderator etc. For free.

But since September 1st 2008 it's discontinued (http://skypecasts.skype.com/intl/en-us/).

AFAIK a regular skype voice conference call can host maximum 25 people.

The idea of having this kind of voice conf is excellent, I'd definitely join from time to time!

Re: [rules-dev] LiteralRestriction NPE

Hi dave.

So that was found when running the verifier - but you chased it down  
to double handling ?

If so, a bug report would be awesome as all the databtype permutations  
are awesome.

I suspect we wouldn't be near that number anyway.

[rules-dev] Scala

Hey All. I have been looking into scala for sometime, and recently
started using it for a testing tool (kind of a replacement for the
"fit for rules" library).
I have been quite impressed with it, the tool integration (with
intelliJ) is outstanding, and it works nice with maven (even with
mixed java source).

Assuming this goes well, I am thinking of extending the usage of scala
to the server side components of bits of guvnor (obviously the client
is still GWT). Probably in a small way at first (I have found that
common annoying bits of code in java can be much clearer in scala -
examples to come !).

I was interested in what people think about this? Does it make it
harder for people to get into the code (I am not aiming to write the
densest scala, just use it when approriate)?

The main downsides I see are: Eclipse support - the plugin for eclipse
for scala is not great at the moment (netbeans or intelliJ would be
better), and general familiarity for people to read (although I
personally think it would take anyone who reads this list minutes to
learn enough to follow the simple things I would do).

Thoughts? Objections?

FAQ: Why scala? well its closer to java in intent then all other
popular JVM languages (ie its static) and compiles down similarly to
result in similar performance (better in some cases). I use "closures"
a lot (thanks to GWT that got be in the habit) but the inner class way
of doing it in java gets combersome.

Re: [rules-dev] Scala

I'm only an observer to this list, although greatly impressed by what you guys have accomplished,
outstanding to be honest. Just a quick question though, have you looked at Groovy? Not to get into
religious language wars, but you might get the same compactness and literate style with perhaps more
fluid integration w Java code.

Groovy isn't a statically typed language, which imho doesn't make it 
suitable for large complex projects. It was partly for that reason, and 
performance both runtime and compilation time, that we went with MVEL 
for the default consequence language over groovy.
