Re: 12.7 million downloads for 2015
Hi Guillaume, Very impressive numbers indeed! Groovy 2016 here we come! Best regards / Med venlig hilsen, Søren Berg Glasius Hedevej 1, Gl.

From: Guillaume Laforge Reply: users@groovy.apache.org Date: January 7, 2016 at 23:28:53 To: users@groovy.apache.org Subject: 12.7 million downloads for 2015 Hi again, As the year ended, I collected the latest download figures from Maven Central and Bintray. In 2015, Apache Groovy's been downloaded 12.7 million times! With about 8 millions from Maven Central and 4.7 millions from Bintray. Historically, Central represented the biggest chunk, but interestingly, for the last quarter, the downloads are even between the two. The total figure above doesn't account for the first quarter numbers from Codehaus, as Codehaus is no more and I didn't have access to the latest figures there. And with Apache, you can also download Groovy from dozens of mirrors worldwide, and I don't think we can have a consolidated access to those numbers either AFAIK. For reference, from memory, we had 4.5 million downloads in 2014, 3 millions in 2013, and 1.7 million in 2012. So that's a big increase! Clearly, the move to the Apache Software Foundation seems to have sparked the interest of new Groovy developers. Let's make 2016 another Groovy year for you all!

Re: float/double calculation bug ?
Hi,
This discussion does not belong on the dev mailing list, but the user

Re: float/double calculation bug ?
You are running into Floating point rounding in the JVM, which is not a
Groovy bug.
Your code can be salvaged by using BigDecimal:
def calc = { amount, ttl ->
BigDecimal rtn
if (amount[-1] != '%') rtn = amount.toBigDecimal()
else rtn = ttl / 100.0 * amount.replaceAll(/%\Z/, '').toBigDecimal()
rtn
}

I think it makes perfect sense that you can do the same calculations with
java.time.* as you can with java.util.Date

Re: Groovy Champions proposal feedback
I disagree with MG. A star is an object that shines, and in this case shines light on the Groovy language and ecosystem. Hence I think the name is both professional, and since it can be directly linked to the star in the Groovy logo I think it makes perfect sense. In sports you also have star players and in music (and Java) you have rock stars. That you can find examples that relates to games on Nintendo does not make a valid point IMO. The "All Stars" just makes it so much better - as that's what Paul, Jochen and others are . My few cents worth. /Søren On Sun, 18 Feb 2018 at 17:02 MG wrote: > > > On 18.02.2018 13:38, Eric Kinsella wrote: > > +1up on Groovy Stars. > > > "Get a life" ;-) > > But seriously, all the people one-upping "Groovy Stars" - consider whether > that name really sends the right professional message with regards to > Groovy ?

Re: Groovy Champions proposal feedback
@Mario Very good thoughts, I really like the idea that an award is permanent, I believe that goes for Java Champs as well. Naming wise, Groovyssimo is fun, but not naming material for an award :-) But we need to narrow down the name-space to something realistic that can be voted on.

Re: [DISCUSS] Groovy 2.6 potential retirement to focus on Groovy 3.0
While the project I'm on is still on JDK 7, but due to Grails 2.x I think that option 3 is the best way to move forward (and nudge projects on to a higher version of Grails as well). /Søren On Wed, 13 Jun 2018, 09.42 , wrote: > I agree on option 3 (abandon 2.6 immediately). > > > > JDK 6 or 7 is not in use anywhere that I have project visibility. > > > > Full support for JKD9+ is becoming a pressing issue.

Re: groovy.json.JsonSulper
First off, user questions should be sent to users@groovy.apache.org not
d...@groovy.apache.org, as the later is for the dev team to discuss the ins
and outs of Groovy, I have added users@groovy.apache.org to continue the
conversation there
Second, I just tried your code in Groovy Console on Groovy 4.0.1/Java 8 and
it worked, so you need to provide more information about what version of
Groovy and Java you are using.
Bonus, this:
def req = new URL("https://jsonplaceholder.typicode.com/todos/1
").openConnection();
def postRC = req.getResponseCode();
def streamText = req.getInputStream().getText()
can be replaced with:
def streamText = 'https://jsonplaceholder.typicode.com/todos/1'.toURL().text

Re: Dynamic assignment of list name in iterator statement?
Hi Jim,
It is possible:
languages = ['english', 'french', 'spanish']
englishCharsList = ['a','b']
frenchCharsList = ['c','d']
spanishCharsList = ['e','f']
languages.each { lang ->
this."${lang}CharsList".each { ch ->

}
}

Re: Dynamic assignment of list name in iterator statement?
Hi Jim,
If your switch hits "English" it will also set the rest of the cases. You
need a "break" after "containsEnglish = true" - just like in Java

Re: String comparison tests on exception messages keep failing due to >'< character keeps getting removed!
Hi Tommy,
This works:
class Library {
boolean someLibraryMethod() {
throw new RuntimeException("'" + "LAZY DEVELOPER! This is a test" + "'")
}
boolean someOtherLibraryMethod() {
throw new RuntimeException("'LAZY DEVELOPER! This is a test'")
}
}
class LibraryTest extends Specification {
def lib = new Library()
def "someLibraryMethod returns true"() {
when:
def result = lib.someLibraryMethod()
then:
def e = thrown(RuntimeException)
e.message == "'" + "LAZY DEVELOPER! This is a test" + "'"
e.message == "'LAZY DEVELOPER! This is a test'"
}
def "someOtherLibraryMethod returns true"() {
when:
def result = lib.someOtherLibraryMethod()
then:
def e = thrown(RuntimeException)
e.message == "'" + "LAZY DEVELOPER! This is a test" + "'"
e.message == "'LAZY DEVELOPER! This is a test'"
}
}
With Java 21 (21.0.3-tem) and Groovy 4.0.21

Re: Sort on linkedlists with double values (inside main list)
But when you sort on the value that is an ArrayList ([it.y, it.x]) you rely
on the *hashCode()* of that ArrayList not the values inside.
So it is a coincidence that it works for others than Float/Double. The
right syntax in Groovy is as described by Paul King.

Re: not sure about Collection.intersect
Hi Paul,
c1 contains one instance of TestClass, c2 contains another. Those two are not
equals, because they probably do not implement the equals method, and thus
comparison is done between object references in memory, and they are different,
being two different objects.
if you equals was implemented to compare the name of TestClass I'm pretty sure
it would work.

Hi – I’d like to get a list of objects from collection A that exist in
collection B using intersect() but I’m getting no results:
def c1 = []// as Set
def c2 = []// as Set
c1 << new TestClass(name: 'mike')
c2 << new TestClass(name: 'mike')
println c1.contains(c2[0])
assert c1.intersect(c2).size() == 1
Output:
true
Assertion failed:

import groovy.transform.EqualsAndHashCode
@EqualsAndHashCode(includes = 'name')
class TestClass {
String name
}
Is intersect only for simple types?

And by the way,
the easy way to implement equals and haschode is this:

@EqualsAndHashCode
class TestClass {
String name
}

I have to look at the implementation of the `intersect` method to be sure but
does your TestClass class overwrite `hashcode` and `equal`? There should be a
way to compare the instances of said class.

Re: Groovy Running Slower With More Memory
Hi Daniel, Without knowing for sure, I would think that setting the minimum heap size to 20G would take some time to allocate. What about just setting the maximum heap size, and let the JVM handle the minimum size, or start lower, like 2G.

I've been running some Groovy 2.4.2 scripts on a Windows 7 64-bit PC with 16GB of RAM. My scripts are memory intensive SQL Server DB manipulators, and I have modified startGroovy.bat to: %JAVA_OPTS% -Xms8192M -Xmx8192M I recently gained access to a new server running Windows Server 2012 that has 32GB RAM and lots of flash disk, so I thought giving Groovy more RAM might allow the scripts to run faster. So I installed Groovy on the server and modified startGroovy.bat to: %JAVA_OPTS% -Xms20480M -Xmx20480M But the new server runs my scripts about twice as slow as my PC. This is true even with the exact same RAM settings in startGroovy.bat. I don't know if I should expect to see a large decrease in run time based on additional RAM, but an increase seems odd to me. Could this be due to OS differences? Thanks!
Re: re-using a comparison closure
Hi Guy
Just assign the variable
def comapreVersions = { a,b ->
return getVersion(a).toInteger() <=> getVersion(b).toInteger()
}
and then use it in your sort:
list.sort(compareVersions)

Subject: re-using a comparison closure
Hi!
I have to sort a list of strings based on a number within the string . . . I
am able to sort using something like:
list.sort( { a,b -> getVersion(a) <=> getVersion(b)})
I need to use this in a bunch of places in my code and was hoping to replace it
with a method, like:
list.sort( compareVersions)
with compareVersions:
def compareVersions(a, b) {
return getVersion(a).toInteger() <=> getVersion(b).toInteger()
}
putting the method (compoareVersions) into the sort as a param doesn't work.
Anyone know what I'm missing?
Thanks!!
Guy
Re: re-using a comparison closure
Hi
You can define it in a class as a static closure
class Sorters {
static compareVersions = { a,b ->
return getVersion(a).toInteger() <=> getVersion(b).toInteger()
}
}
and use it like:
list.sort(Sorters.compareVersions)

Thanks! Now, I have a number of methods that need access to that closure . . .
Can I make the closure global? Is there a better way?
Thanks again,
