I suspect the best place for the debate is the Gant Users email list, so if people could be careful about which list they reply to when replying then people not interested in the debate will not get flooded Russel Winder 2008-10-04T09:07:37 http://comments.gmane.org/gmane.comp.lang.groovy.user/36322 i'm not sure if using a Map to "extend" a Java class is an officially supported feature anyway. The doc only say it can be used to implement interface. Say, for the following Java: public class TestInner { public String debug(){ return "outer debug"; } public class Inner { public String debug(){ return "inner debug"; } } } The following does work: def inner1 = ['debug':{return "outer debug 1"}] as TestInner println inner1.debug() But not : def inner2 = ['debug':{return "inner debug 1"}] as TestInner.Inner println inner2.debug() There is compilation error. Caught: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Error casting map to TestInner$Inner, Reason: Error creating proxy: startup failed, Script1.groovy: 1: unexpected token: $ < at > line 1, column 16. 1 error JIRA it as bug or request for new feature? :-) regards, mingfai Mingfai 2008-10-03T17:03:55 http://comments.gmane.org/gmane.comp.lang.groovy.user/36319 Hi guys, I've got a junit test class which extends GroovyTestCase, when the class involves some Groovy class/script which generate closures classes, the test will fail along with the message like following: junit.framework.AssertionFailedError: Class MyTest_closure1 has no public constructor TestCase(String name) or TestCase() Does anyone have idea to fix this?

For example, I want to produce an "<br>" from MarkupBuilder but I got a "&lt;" and "&gt;" from the source code that it generates.

Does anybody know if multiple assignments are working now in groovy-1.6-beta2 ? Thanks! Regards, Sergey Bondarenko. Sergey Bondarenko 2008-10-03T08:10:14 http://comments.gmane.org/gmane.comp.lang.groovy.user/36291 This is probably a silly question, but why is there no Date.format(..) GDK method? It would basically be a wrapper for SimpleDateFormat so you could do this: new Date().format( 'yyyy-MM-dd' ) // returns 2008-10-02 The same could be done for Calendar. Does something like this seriously not already exist in the Groovy API? --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email Tom Nichols 2008-10-02T18:49:21 http://comments.gmane.org/gmane.comp.lang.groovy.user/36286 " If I use the windows command (cmd.exe) and type chcp 65001 perl -wle "binmode STDOUT, q[:utf8]; print chr() for 0x410 .. 0x430;" I get the Russian alphabet, one character every other line (not quite what I want but close) with the proper Cyrillic glyphs.

Unlike Gus and Jerome's presentation on their Grails and testing experiences (which was great and I bet what most people turned up to hear), my talk really was unplanned, definitely unrehearsed, and literally made up as I went along. Special thanks to the people who came up afterwards and said they enjoyed the talk -- it made me feel a lot better about the unstructured and disconnected nature of the session. I thought the basic questions I was trying to raise worth summarizing and broadcasting more widely. I am not sure if discussion on mailing lists is the right mechanism for continuing the discussion and whilst this email has gone to the Grails user list as well as the Groovy user list, this is definitely a Groovy rather than Grails issue. The backdrop here is that now every computer is a parallel computer yet most code is still sequential code. Most programmers are very poor at writing concurrent code and even worse at parallel code.

When creating a shortcut to a property, I get a strange MissingMethodException calling a gettter, but if I use a property access, it runs ok. I succeeded in reproducing the error in a more simple code, that goes below: -------------------------------------------------------------------------- class A{ def someMethod() { 'some method' } } class B extends A{ private String reallyBigPropName = 'property' public String getReallyBigPropName() { reallyBigPropName } public void setReallyBigPropName(String reallyBigPropName) { this.reallyBigPropName = reallyBigPropName } } ExpandoMetaClass.enableGlobally() A.metaClass.invokeMethod = {name, args -> def method = A.metaClass.getMetaMethod(name, args) if(method){ if(name == 'someMethod') return 'someMethod intercepted' return method.invoke(delegate, args) } throw new MissingMethodException(name, delegate.getClass() João Paulo Mafra 2008-10-01T13:30:15 http://comments.gmane.org/gmane.comp.lang.groovy.user/36255 Hi, I have the following 'xml' file: <range> <item stvalue="${x} &lt; ${estimatedtime}" value='0'/> <!-- and so on --> </range> And, this is my groovy program: #!/usr/bin/env groovy def xmlreader = new XmlParser().parse(new File('range.xml')) def result = [:] xmlreader.item.each { result[it.'< at >value'] = it.'< at >stvalue' } estimatedtime = 20 x = 35 result.each { key, value -> println "|${value}| ${value.class.name}" println new GroovyShell().evaluate(value) } Then, run the script, and I got this: |${x} < ${estimatedtime}| java.lang.String Caught: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, Script1.groovy: 1: unexpected token: $ < at > line 1, column 1. 1 error at t$_run_closure2.doCall(t.groovy:11) at t.run(t.groovy:9) at t.main(t.groovy) Some one knows what's wrong with the code above?

The editor works wonderfully, but when I try to run code I get strange errors: Exception in thread "main" java.lang.ExceptionInInitializerError at desktopapplication1.DesktopApplication1.main(DesktopApplication1.java:43) Caused by: java.lang.RuntimeException: Uncompilable source code - desktopapplication1.TestGroovy is not abstract and does not override abstract method setMetaClass(groovy.lang.MetaClass) in groovy.lang.GroovyObject at desktopapplication1.TestGroovy.<clinit>(TestGroovy.java:10) ... 1 more Anyone know why this would be? I was thinking it might be some kind of conflict since I have 1.6 installed - but even launching it from a clean environment doesn't seem to help. Cheers! Simon. simonz 2008-10-01T04:47:18 http://comments.gmane.org/gmane.comp.lang.groovy.user/36245 I'm able to read content written in builder DSL from a file and generate xml using StreamingMarkupBuilder. However I'm unable to figure out the difference between two ways of creating and passing closure to StreamingMarkupBuilder.bind(). One fails and other works. Delved into debugging using Intellij IDE but with all the MOP going under the hood its not a trivial task to understand what is going on. Hopefully the MOP experts here can help me. 1. Closure using return - import groovy.xml.StreamingMarkupBuilder def clsrStr = "return { root{ child{}} }" def clsr = evaluate(clsrStr) def xml = new StreamingMarkupBuilder().bind(clsr) xml.toString() This works with following o/p <root><child></child></root> 2. def clsrStr = "{ -> root{ child{}} }" def clsr = evaluate(clsrStr) def xml = new StreamingMarkupBuilder().bind(clsr) xml.toString() This fails with the following exception.groovy.lang.MissingMethodException: No signature of method: Script1$_run_closure1.doCall() is applicable for argument types: (groovy. Kumar Pandey 2008-10-01T03:54:51 http://comments.gmane.org/gmane.comp.lang.groovy.user/36228 Hi, I have noticed a couple of times now that if I have a closure like this: def c = { String arg1 -> ... } the closure is not called if I pass a GString: c("Value $i") Is this behaviour intended? Should the GString be coerced to a String for the closure? I've seen it with GrailsMock and a closure defined in a Gant script.

So i need your help to translate my java code below in groovy :) class A { public void methodOne() { // some behaviours } public void methodTwo() { // some behaviours } } A obj1 = new A() { // anonymous subclass public void methodOne() { // modified behaviours } }; A obj2 = new A() { public void methodTwo() { // some behaviours } }; I usually use this technique in testing. But in groovy, i have to explicitly define two subclasses which is more verbose. Do you know how to do it in groovier way?

Greets A_Grails_User 2008-09-30T09:52:54 http://comments.gmane.org/gmane.comp.lang.groovy.user/36209 Fortify has Groovy listed on https://opensource.fortify.com/ as "defect free". It indicates that it is free from whatever security vulnerabilities their tool checks for. I am not sure what that is but good to know I guess. I am also unsure how old that list is. They also have "Grails" listed as "Groovy for Rails".
