Re: [groovy-user] GPath with dot in a String

Mingfai — 2008-07-25T08:36:06

given the requirement is a configurable, nested GPath, I could think of the following way to achieve: def a = [b:[c:[d:"a.b.c.d"], c1:"a.b.c1"]] println a.'b.c.d' // ideal solution, so ppl can't use dot as String key, normal java property or xml node name will not contain a dot anyway println a.'b.c1' //ideal solution def readBC0D = {t-> t.b.c.d} // or def bc0d = { delegate.b.c.d} and add to metaclass def readBC1 = {t-> t.b.c1} println readBC0D(a) println readBC1(a) println a.with{readBC0D(it)} println a.with{readBC1(it)} so instead of defining a String to represent GPath, I define a closure to hold the GPath. Is it the best way? btw, is it good for Groovy to support eval a GPath? if so, I could fire a JIRA issue. Regards, mingfai On Fri, Jul 25, 2008 at 4:17 PM, Mingfai public.gmane.org> wrote:

Re: [groovy-user] GPath with dot in a String

Mingfai — 2008-07-25T08:17:27

Let me see if I could explain. I'm trying to extract some values from an object graph (say, to a Map). The extraction path may be in different level of the object graph, e.g. a.b.c and a.b.c.d, and I would want the extraction path be configurable. If there is such an API that I've mentioned, it should be straightforward. it's sound useful to me. otherwise, i wonder i can hardcode the paths in a closure.

[groovy-user] GPath with dot in a String

Mingfai — 2008-07-25T07:31:48

hi, I wonder if it is possible to define a full GPath (with dot(s)) in String and retrieve the value. e.g. def a = [b:[c:'value']] println a.b.c // work, print 'value' println a.'b'.c // work, print 'value' println a.'b.c' // it behaves correctly to show 'null' and I wish to find an alternative way to achieve this to retrieve the 'value' Is there an API similar to obj.getAsGPath(a, 'b.c') Thank you very much regards, mingfai

Re: [groovy-user] groovysh tab completion

No sweat. How about the next best thing. Is there a method or property for a groovy object that reports all the properties and methods that can be applied to it? \n in groovysh seems to come close.

Re: [groovy-user] groovysh tab completion

Jason Dillon — 2008-07-24T23:44:59

No eta on that atm, due to the primitive parser support in groovysh to detect valid mulit-line syntax. As of right now the compiler does not provide adequate information about partially and fully complete Grroovy syntax, making it near impossible to implement more interactive completion... sorry :-( --jason On Jul 25, 2008, at 12:48 AM, mgc wrote: --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email

Re: [groovy-user] question about how to execute a command line batch via groovy function?

Paul King — 2008-07-24T23:06:21

I guess you have several options. I would probably start with something like: def mh = System.getenv('MAVEN_HOME') "cmd /c $mh/bin/mvn -s temp-settings.xml $args".execute() which will work provided maven doesn't produce too much output. If it does produce too much output windows freezes up. A known buffering issue for windows. See link below for ways to get around that: http://groovy.codehaus.org/Process+Management In particular, you might want to look at using waitFor() and/or consumeProcessOutput(). Cheers, Paul.

[groovy-user] [ANN] New version of the Groovy Eclipse plugin

Guillaume Laforge — 2008-07-24T21:28:57

Hi all, The Groovy Eclipse team released an updated version of the Groovy Eclipse plugin. In this new release, the main points of interest: - the plugin has been updated to use Groovy 1.5.6 - and it is also working with the recent Eclipse 3.4 You can find the Groovy Eclipse plugin as a Zip file here: http://dist.codehaus.org/groovy/distributions/update/GroovyEclipse.zip And you can point your Eclipse update center at the following location: http://dist.groovy.codehaus.org/distributions/update/ Upcoming version of the plugin will feature the first refactorings (extract method). You can discover more on the topic thanks to the students working on this project as part of their Bachelor thesis at University of applied sciences, in Rapperswil, Switzerland, here: http://sifsstud4.hsr.ch/trac/GroovyRefactoring Also, don't forget to read Groovy plugin developer James Ervin's words on the roadmap of the plugin: http://iacobus.blogspot.com/2008/07/roadmap-for-groovy-eclipse-work.html Congratulations to everybod

[groovy-user] Q: Windows Installer /D option

I must be doing something stupid. I cannot get the /D option in the installer to work -- it keeps using "C:\Program Files\Groovy" as the install directory. I have tried "/D:c:\Groovy", "/D=c:\Groovy", and "/D c:\Groovy", none of which worked. Any ideas?

[groovy-user] groovysh tab completion

From google and this forum, I infer that groovysh doesn't tab complete objects and object methods/properties, but that it's coming. What's the ETA? Tab completion ala irb or ipython would be quite worthwhile. Pl. advise. Thanks.

[groovy-user] Inheritance for XMLMarkupBuilder?

David C. Hicks — 2008-07-24T17:32:26

Hi, I'm creating an XML builder. One of the classes I want to write XML for is an extension of another class. Is there a way to get the base class to be responsible for writing its own attributes in the XML? Example: Suppose we're writing XML to represent some shapes in a drawing. In my builder I call Square.generateXml(xmlBuilder). The Square class clearly has access to all of the attributes, but since Circle and Rectangle also use x,y I'd rather let the Shape base class handle writing those values. In this example, Square would write the size, but Shape would write x and y. Only, I can't quite figure out how to do that. Any help?

[groovy-user] Binding as the user requesting the update

Joel Reed — 2008-07-24T01:39:49

I'm building a web application that queries a directory server. Most of the time I can do so anonymously, but for updates, I want to bind using the username and password of the logged in user. Ideally, I could write: def ds = GldapoDirectory.newInstance( "example", [ url: "ldap://ds.example.com", userDn: session.username, password: session.password ] ) ds.updateEntry("dc=example,dc=com,o=root", [ name: "Example Inc." ]) But I seem to have to create a list of javax.naming.directory.ModificationItems. Which looks painful, but may be the best solution? Alternatively, I could use something like: def org = Organization.getByDn("dc=example,dc=com,o=root") org.name = "Example Inc." org.update() But I can't seem to get a new, per user/update directory instance with the schemas loaded so Organization can get the right methods injected. Any ideas on the best way to use Gldapo to solve this use case? jr --------------------------------------------------------------------- To unsubscribe from this li

Re: [groovy-user] source id

James Williams — 2008-07-23T20:16:33

Danno will quickly chime if this isn't the preferred way to do it. The registered ids and their corresponding components are registered with the builder in a map called variables. Run the find closure on this map. import groovy.swing.SwingBuilder import javax.swing.WindowConstants as WC def swing = new SwingBuilder() def frame = swing.frame(layout:new java.awt.FlowLayout(),size:[200,200], defaultCloseOperation:WC.DISPOSE_ON_CLOSE){ button(id:'btn', actionPerformed:{evt -> }) button(id:'btnw', actionPerformed:{evt -> println swing.btn == evt.getSource() println swing.variables.find{it.value == evt.getSource() } }) } frame.show() On Wed, Jul 23, 2008 at 8:11 AM, Finn Herpich < finn.herpich-HLWg83l9DMevRySba1qPKDqC5zpoNJ7mdz/iME4q6zg< at >public.gmane.org> wrote:

Re: [groovy-user] MethodClosure weird behaviour

Pierre Thibault — 2008-07-23T12:54:59

this with every object that you generate"(?) Aren't you better off actually 'generating' a list and then running an 'each' with your command/action closure. Definitely not. If the list is really small, this is OK. But if the list is big, it is wasting memory and time. The solution for me is: generator { // do something... } The only problem is exiting the closure before all the values are processed. But this is something missing in the Groovy language itself. ________________________________ Pierre ----- Original Message ---- From: Saager Mhatre public.gmane.org> To: user-i9PBDF1N6cxnkHa44VUL00B+6BGkLq7r< at >public.gmane.org Sent: Wednesday, July 23, 2008 8:13:40 AM Subject: Re: [groovy-user] MethodClosure weird behaviour Basically, Pierre, I don't get your generator.
