Your Groovy or Grails Open Source Projects

[Chee Kin Lim]

Hi there,

I think we lack of common location to share/promote/announce our Groovy/Grails open source projects. So, I created this topic.

Kindly share/promote/announce your projects in this topic regardless whether it is in active development/maintenance as other developers may make use and contribute to your projects and make it better.

Me first:-
Grails Activiti Plugin (activiti) - Enabled Activiti BPM Suite support for Grails
Activiti Spring Security Plugin (activiti-spring-security)
Grails Dynamic Domain Class Plugin (dynamic-domain-class) - Create domain class on-the-fly
Grails Form Builder Plugin (form-builder) - Create Online Forms without Coding
JQuery Validation UI Plugin (jquery-validation-ui) - Client Side Validation without writing JavaScript
Mahout Recommender Plugin (mahout-recommender) - A Scalable Recommendation System

Please see other Grails plugin projects at http://limcheekin.blogspot.com/p/my-grails-plugins.html

I'd love to find out more about your projects!

Best regards,
Chee Kin

Hi Chee Kin,

I encourage everyone to write plugins but should try to announce and engage the community at user-grails mailing list. That said, here are my plugins I published over the years

http://www.grails.org/Sparkline
http://grails.org/plugin/bcrypt -- not uploaded yet
http://grails.org/plugin/compress#
http://code.google.com/p/party-time
http://grails.org/plugin/pretty-date

I think my old lucene plugin is still somewhere but I encourage you guys to just use the new elasticsearch plugin.

My plugins are usually simple and straight forward so that more people can use it, or read the source code and extend the plugin.

:-)

Hi Seymour,

Thanks for quick response. Yeah, I fully agreed that publish the plugin release announcement to user-grails mailing list, but also don't forget to cc to this group.

Thanks for sharing your list of plugins here.

Cheers,

Hi CK,

Thanks for sharing.

This logic thingy represent the diamond shape in BPMN or activity diagram, I am not impress as it is targeted to developer instead of subject matter expert

From my experience, subject matter experts are master in using spreadsheet to define logic and rules such as Ms Excel which represent as Decision Table in business rules engine.

FYI, I am evaluating business rules engine to fit in the diamond shape of BPMN for the Grails Activiti Plugin.

Just my 2 cents. :)

interesting point about the spreadsheet.

i have used jquery sheet before for adhoc queries (with a custom formula to retrieve data from our database) - this with a combination of other formulas and conditional formatting whether a price pattern is on the uptrend or otherwise. but ther resulting data is not stored anywhere.

how would your decision table work ?

[Chee Kin Lim]

Hi Raja,

You may do some reading about decision table at http://en.wikipedia.org/wiki/Decision_table

aaahhh.... interesting depiction of the decision table. nice view point, i am more accustomed to decision trees in statistics, and i guess decision trees are more understandable in 'if.. else' statements with multiple branches. but i can see that decision tables would be really good for multidimensional models - reminds me of matrices in a-level mathematics.

[Chee Kin Lim]

Aha! your math is better than me :).

Enjoy your weekend!

Cheers,

[Raja Iskandar Shah]

just wondering, does this 'decision tables' that you envisaged would be something like matrices ? not really mathematical matrices but decision matrices ? that users are able to add new 'columns' / 'rows' ? also that a result from 1 matrix can be used as an input into another matrix ? so theoretically you could have multiple layer of decision matrices ?

[Chee Kin Lim]

Hi Raja,

If I understand your statements correctly, you mean nested "if-then-else if-else" logic in programming logic, then the answer is yes.

Cheers,

Hi Azzuwan,

I welcome you to the group.

If it is so nice, why not you just use it instead re-invent the wheel (build something similar)?

Best regards,

Hi folks,

I'm new here. I just saw automated business logic yesterday. It's quite nice. I've been trying to figure out how to build something similar myself .

Hi Chee Kin,

Thanks for the welcome. I'm  trying to convince my client to use it and factor in the commercial support in their budget. Has anyone in here use ABL before?
