http://www.warneronstine.com/blog/articles/2006/12/07/new-project-chama en-us 40 Where technology and art disappear <p>So, where has all this DSL stuff been leading? One of my projects that has been sitting on the back-burner for a while has been <a href="http://warneronstine.com/cgi-bin/trac.cgi/">Chama</a>. Chama was born out of the frustration of writing the same boiler-plate code over and over for database-backed sites that are run on Tapestry. While you can certainly use something like Trails I was not happy with the additional amount of configuration I needed to do in order to get the forms to look and behave the way I wanted them to.</p> <p>Why not use Ruby on Rails then, or even <a href="http://grails.codehaus.org">Grails</a> if I want to stick with the Java theme?</p> <p>A variety of reasons:</p> <ul> <li>I'm familiar with Tapestry, Hibernate, etc.</li> <li>I'm very familiar with Java</li> <li>I want to learn <a href="http://groovy.codehaus.org">Groovy</a> as a language</li> <li>I don't want to switch out my deployment options to have to deal with deploying my apps to a new server and having to configure it all over again so that it'll run RoR</li> <li>I like generators ;-), no really this is an exercise that I want to undertake and if others find value in it that's great</li> <li>Mostly to make it easier for me to get some app ideas I've had off of the ground</li> </ul> <p>What will Chama use:</p> <ul> <li>Groovy as the primary language, with some Java thrown in where needed</li> <li>Most likely <a href="http://yaml.org/">Yaml</a> for configuration with <a href="http://jyaml.sourceforge.net/">JYaml</a> for dealing with it</li> <li>Quite possibly several DSLs for each area (Model, View, Controller)</li> </ul> <p>I don't know yet exactly how far I'm going to take Chama, mostly I just want to get a tool together that will help me build stuff. If others find value in it and it gets extended from there and heads in a direction I never thought about, great! All the code will be available under an Apache License once I start working on stuff. I have some tentative dates setup in my <a href="http://warneronstine.com/cgi-bin/trac.cgi/">Trac</a> instance (what?! using Python for a Java app?). Comments are welcome, and I will use this blog to announce releases as they happen, the first milestone is set for 12/22/06 (oops was tomorrow, moving to two weeks, wow it's been two weeks since I first set this up already).</p> Thu, 07 Dec 2006 22:50:00 -0700 urn:uuid:9acd0cf1-1b27-4e2e-a9f1-913a59d5ab06 Warner Onstine http://www.warneronstine.com/blog/articles/2006/12/07/new-project-chama programming dsl java tapestry groovy chama http://www.warneronstine.com/blog/articles/trackback/4
