Re: [groovy-user] Problem with Date()
It may be a bug but not with Date. 30*24*60*60*1000 ==> -1702967296 I thought we got numeric promotion in Groovy but obviously not. You can avoid the overflow by specifying a bigger type: 30*24*60*60*1000L ==> 2592000000 30*24*60*60*1000.0 ==> 2592000000.0 But that won't help because you can't add a number bigger than Integer to a Date: new Date() + 30*24*60*60*1000L ==> groovy.lang.MissingMethodException: No signature of method: java.util.Date.plus() is applicable for argument types: (java.lang.Long) values: {2592000000} Jim --- Wings - Why take the train when you can fly? http://IFCX.org --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |

Re: [groovy-user] problems compiling with 1.6-beta1
I think, I localized the problem.

Re: [groovy-user] grep usage
So you have a list of items (java beans can be accessed the same way as maps)... def items = [ [id:1,name:'aaa'] , [id:2,name:'bbb'], [id:3,name:'ccc' ] ] items.grep{ it.id ==1 || it.id == 2 }.each{ println it.name } prints: aaa bbb 'it' is the default name of the current element in the closure's iteration. If you want to override this you can do: items.grep{ p -> p.id == 1 || p.id ==2 } -mark On Fri, May 9, 2008 at 3:06 PM, Vinny |

Re: [groovy-user] Groovy exception when using sql server money datatype and zero value
Yeah, that's printf, although I get a different message with the IAE. A float formatter will take a float or BigDecimal, but not int. Conversions are divided into the following categories: General - may be applied to any argument type Numeric Integral - may be applied to Java integral types: byte, Byte, short, Short, int and Integer, long, Long, and BigInteger Floating Point - may be applied to Java floating-point types: float, Float, double, Double, and BigDecimal So if you use a floating point format you need to be sure to supply an argument with a decimal point. But when the Groovy SQL type conversions are being done, it sees the zero value and chooses Integer for the type. You can do it this way: db.eachRow("select testmoney from javaweb.dbo.money") { money -> printf "Money is %4.2f\n", money.testmoney as Float } or better for monetary amounts: db.eachRow("select testmoney from javaweb.dbo.money") { money -> printf "Money is %4.2f\n", money.testmoney as BigDecimal } But I |

Re: [groovy-user] dif between def obj = new MyObject() vs MyObject obj = new MyObject()
Ed Clark-2 wrote: It may still be true that specifying types can slow down a program - I haven't benchmarked this in a while. The overhead comes at assignment where you have to cast or convert the Object result of the expression to the target type of the assignment. You also get boxing/unboxing costs for primitive types. I would not be over concerned about this if I were you. There are lots of gains to be made in optimising the runtime system so your programs will get faster without you having to "optimise" them yourself. At some point the increased speed will begin to make this overhead a larger proportion of the execution time of your program and you can begin to worry about tuning the 5%-10% of your code which will make a difference. Personally I very rarely type a variable unless it's part of the interface to some Java code. John Wilson |

Re: [groovy-user] dif between def obj = new MyObject() vs MyObject obj = new MyObject()
Wow, I didn't expect that answer. How recent is "very recently"? is there a penalty in 1.5.6? Was this due to things like extra type checking on assignment? Anything targeted to 1.6? Just wondering whether to start being more thorough in specifying types. Although I had said that I think it's a good idea to specify types, I'm also quite lazy ;-) and tend to leave them off if there's no performance payoff (especially if there's a penalty).

Re: [groovy-user] RFE: Add withWriter and withOutputStream to URL/URLConnection
Marc, Looks interesting to me. On the "response" part, it may be nice to have a way to specify the handling of the different final response codes: - being able to retry on (some) 5xx responses (after some specified delay), - being able to select the "best" next hop on a 3xx response that has a redirection list, - error handling of 4xx or 6xx responses (e.g., using an alternate URL), - maybe even being able to say how to handle login challenges (tho' I'm not to sure how easy it is to detect those) Ed Clark Marc Palmer wrote: --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |

Peter Niederwieser wrote: I believe the original motivation to allow optional typing was to allow proper integration with Java. If you can declare the parameter and return types of methods then you can easily and clearly subclass Java classes and implement Java interfaces.

My general rule of thumb with Groovy is to make anything which is likely to be seen from a Java program typed and declare everything else untyped.

Re: [groovy-user] dif between def obj = new MyObject() vs MyObject obj = new MyObject()
Just curious - are there any performance benefits to specifying the type, either compile time or run time? I know that some languages can speed things up if given some type hints. (Given the extra dynamic nature of Groovy, there may be none.) I do think there are other benefits to explicitly typing, e.g. adding that little bit of additional info to make the code easier to read and understand.

[groovy-user] Cygwin support in the native launcher
Hi! I and Russel Winder were able to implement support for cygwin style paths in the native launcher. Please see http://groovy.codehaus.org/Native+Launcher#NativeLauncher-Pathsoncygwin The support is a little experimental, so it is not included in the prebuilt binaries on the wiki page or in the windows installer, i.e. you have to build the binary yourself. Instructions can be found on the wiki page. Note that you do not need to build the native launcher in cygwin in order to have cygwin support (but you can, of course). Please note that the "cygwin" version of the native launcher works as normal native launcher when used outside cygwin, i.e. uses normal windows paths. Someone asked for cygwin support a long time ago. If anyone actually uses this, please drop me an email and tell me how it works for you. And please report any issues (there are none known ATM). -::Antti::- |

Re: [groovy-dev] startGroovy.bat
I have already made a number of suggestions, but no-one picked up on them. I think the best bet is for me to make the changes in a branch rather than just change trunk and then put a patch up on JIRA for people to vote on and if approved apply -- a professional approach to changing trunk ;-) The only problem is that I haven't been able to take a Bazaar branch of Groovy as yet. I am hoping to be able to do this next week then I can put it up somewhere public so that anyone can branch it. I (and anyone else) will then be able to branch as and when the whim takes them. I will need to find somewhere to host the mirror branch as it is likely to be 120MB and my server is on the end of an ADSL line. I may look at hosting it on Launchpad as Codehaus is not yet set up for handling Bazaar branches. Once we have the branch Paul and I can also experiment with replacing Commons CLI 1.0 with something sensible. |

Re: [groovy-dev] startGroovy.bat
Possibly, but the way it works at the moment severely restricts the reusability of the script. I think that startGroovy and startGroovy.bat can be tinkered with slightly to make them far more efficacious for launch scripts other than groovy and groovyc. There are built in assumptions that the scripts will all be in $GROOVY_HOME and that $GROOVY_HOME/lib/groovy*.jar is the groovy jar. I don't think it would take much rearrangement to make them far more flexible and therefore usable by groovy-based systems that are not colocated in $GROOVY_HOME. |

Re: final Groovy JSR?
Yes, for sure, conceptually speaking, this would be desired. For Java, this is simpler as a call to a method is directly encoded in the bytecode. No intermediary layer of indirection. It then just depends on the runtime part (JDK classes, third party libraries, etc) But for a dynamic language, in the bytecode you'll find some calls to utility classes handling the double dispatch. Some of them are public APIs (which will be part of the JSR), but others may be present that are specific to each implementation. So we'll have to think deeper as to what we really want to make portable or not. Tricky issue :-) Right. This has always been possible (as long as you have the Groovy runtime on your classpath). We can seamlessly integrate with Java, or any other alternative language for the JVM. But the problem comes when we have to be compatible between different implementations of Groovy. At the basic object level, things are just fine, but it's when you get into metaprogramming techniques that this may be more prob |

Tentative Roadmap
Dear Groovy developers, Now that we have released 1.5, it is time to think about the future of Groovy, by discussing its roadmap. After some discussions at GDC#4 ( http://docs.codehaus.org/display/GroovyJSR/GDC4+Discussions), on the lists, and elsewhere, we've listed possible improvements and new features. Jochen and myself compiled a tentative roadmap this weekend, taking these ideas into account and trying to lay them out across potential release numbers. This is a tentative roadmap. Certain features can be discussed, whether we do want them or not. And there's room for moving features from one to another release. New ideas missing can also be introduced. So it's still pretty open at the moment. Note that the roadmap can change across the course of time according to the progress (or lack thereof) we make on the GEPs (Groovy Extension Proposals). It is not set in stone today, even after our upcoming discussions. The GEPs will drive us through the releases. It is very important that we try to clearly de |

Before going through the new release, let me recap some of the nice things that have been happening lately around Groovy: * JetBrains released a second milestone to the wonderful Groovy & Grails IntelliJ IDEA plugin, so be sure to check it out, as you'll feel at ease developing Groovy with all the |

Thanks to the help of some JBoss developers who've integrated Groovy in JBoss Seam, we've been able to test our support for annotations and generics, and to make sure we would release a quality milestone to our users. Groovy is the first alternative dynamic language for the JVM that supports annotations and generics, so that you can integrate Groovy with any Enterprise application frameworks like EJB 3 / JPA, JBoss Seam, Google Guice, Spring, etc. * Secondly, I'm very happy to report the contribution of JetBrains to the development of Groovy.
