Re: What projects use Groovy as its main development language ?
MIP(aka Murex Interface Platform) of BEA is developed with Groovy 3. There are about tens of thousands LOC in groovy files. P.S. I am not able to provide accurate LOC because I do not work for BEA any more...

Re: What projects use Groovy as its main development language ?
Claz.org uses groovy as main development language. "git ls-files | grep groovy | xargs wc -l" shows about 200k SLOC in tracked groovy files (including tests) across subprojects, which should be about 90% of the codebase. The remaining ~10% is Java (performance-critical parts), Kotlin (Android) and ObjectiveC/Swift (iPhone) On Fri, Jun 26, 2020 at 6:24 PM MG wrote: > A quick survey: Who on this mailing list works on or knows of a project > where Groovy is the main language of development, i.e. it is not used as > "just" a script or DSL language in addition to e.g. Java ? > If possible name the company/country/project and give some impression of > the size of the project (lines of code, # of people working on it, etc), > timeframe of development, and whether it is os or commercial (or both) G-) > > Thanks in advance, > cheers, > mg > > > > -- Andrei Karneyenka, +1 (609) 433-7126

Re: What projects use Groovy as its main development language ?
Since 2008 I maintain Groovy CMS/CMF for my company, written from scratch completely in groovy. Basically it is MVC over Servlet. It uses many java components such as Hibernate as model layer (all model classes are Groovy classes and Hibernate configuration is groovy config files, converted runtime to properties), but whole controller layer is statically compiled groovy code, that will be packed as *.class files into WAR. So, all the backend code is Groovy. There is only one type of resources in backend - XSLT files, used as view layer via Saxon. And yes - this is java web application without Spring. Since then over 100 implementations were made - shops, sites, news resources. Groovy performs well and easy to develop and support. This is definitely not DSL nor scripting
Re: What projects use Groovy as its main development language ?
Mg,
my main client here in Czech Republic allowed me to turn all our WebObjects
projects from Java to Groovy years ago (and still there are non-trivial parts
of the legacy codebase in the original Java :))
Those project include a couple of web applications like e.g., an auctioning
system or a task-specific... let's say database, with a very rich support for
table management and report generation (those are commercial and my client
makes the money on them), plus some internal tools used by us only (for which I
am paid as a programmer, but from my client POV they are, of course,
non-commercial). The sizes of the projects vary from 10 to 50 000 Groovy source
lines, not counting groovy expression embedded in the HTML templates or
untouched .java files (of which there's just a couple; most original Java code
is in not-yet-refactored parts of .groovy sources). I am the main programmer
and maintainer of the stuff, with an occasional help of some subcontractor.
Oldest of them are maintained for fifteen-odd years (which is the time I
started writing WO in Java; before that it used to be the infinitely better
Objective C, but alas, Apple closed that possibility :/ )
From my POV, Groovy is just great, allowing me to at least partially return to
the clean and concise ObjC-like code, skipping the terrible boilerplate and
problems induced by Java: originally, some of the projects exceeded 100 000
Java lines, caused by über-ugly things like
NSArray validOfferItems() {
NSMutableArray ma=null;
if (auction!=null) {
NSArray all=auction.orderedPriceOffers();
if (all!=null) {
ma=new NSMutableArray();
for (Enumeration en=all.objectEnumerator();en.hasMoreElements();) {
DBPriceOffer po=(DBPriceOffer)en.nextElement();
if (po.validOffer()) ma.addObject(po);
}
}
}
return ma;
}
which of course was re-written to
NSArray validOfferItems() {
auction.orderedPriceOffers.findAll { it.validOffer }
}
long ago (I've got a couple of my own ASTTs and extensions to get rid of NPE
and the need to write those ugly ?'s to all the expressions.)
Contrariwise, I rarely use Groovy for scripting. Occasionally, yes, when the
task is too complex; but for a vast majority of my scripts, zsh suffices and
it's more convenient for it's portable anywhere. (Perl might be even better,
but somehow I never found time to learn the thing :))
All the best,
OC
