Hello all,
I've been learning EMF, GMF and Epsilon for the past few weeks and I
have to say I'm quite impressed. They're all very good tools. I
particularly like how I can generate all the GMF models with Eugenia and
customize what I need using some EOL scripts.
That said, I'd like to automate the generation/compilation process a
bit. There are Ant tasks for the EMF2ECore part and Epsilon also defines
tasks for all the ExL languages and manipulating models. However, I
haven't found any for Eugenia itself.
Looking at the o.e.epsilon.eugenia/src/.../*Delegate.java files in SVN,
I think it could be as simple as running epsilon.eol with the
FixGMFGen.eol, FinGenModel.eol and ECore2GMF.eol scripts and the proper
models.
I believe I could just as well grab these files from SVN and copy them
to my project, but it doesn't feel right. I'd like to use the .eol files
which are part of the Eugenia plugin itself, but I'm not sure how to get
at them using the src attribute of epsilon.eol, if at all possible.
Would it be better to just write new Ant tasks in a plugin and wrap the
runImpl methods of the delegates?
Thanks in advance,
Antonio

Thank-you for the feedback. It's great to hear positive reports :-)

Yes, that seems like a sensible approach. However, the tasks that
Epsilon contributes to ANT can only be used to specify file names as
source programs. If URIs could be specified, a platform URI could be
used to reference the EuGENia EOL files from within the EuGENia plugin.
So, one approach would be to add support to the Epsilon ANT tasks for
loading source files from URIs.

The latter sounds like a more specific solution (so would require less
code in the ANT file), but is less flexible. I'm not sure which is more
appropriate.
My colleague, Dimitrios Kolovos, is the primary committer on EuGENia,
Epsilon and the Epsilon / ANT integration. I think it would be best to
gather his views. Unfortunately he is on vacation at present, so we may
have to wait for him to return, in a week or so.
In the meantime, could you open an enhancement request via bugzilla to
track this?
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=GMT& component=Epsilon
If you urgently require a solution, do let me know and I can investigate
this in more detail.
Many thanks,
Louis.

Oops, I didn't notice that the src attribute in the Ant task was of type
File. I'd just assumed it was a path :-/.

Seeing that EolModule#parse is overloaded for URI objects, we could
probably do it by adding to AbstractModule the getter and setter for the
uri attribute, some validation so src and uri don't get used at the same
time, and modify executeImpl so it uses it.

I agree that it is less flexible. I don't think the previous alternative
is that hard to do: perhaps we should try it first.

Yes, that'd be best. I'll see if I can make some time and cook up a
patch, so we at least know if it can be done easily.

Sure :-). Here it is:

No, it's not that urgent. I just thought that it'd be nice, as I'm used
to doing everything with Ant :-).
Thanks,
Antonio

I've not looked closely, but I'm not sure if adding to AbstractModule is
the way to do it. I'd have guessed it could be done purely by adding to
ExecutableModuleTask. Not sure though!

It'd definitely be a nice addition. Thanks for the suggestion and for
investigating. Congratulations on surviving your encounters with the
source code ;-)
Cheers,

Yes, that's how it turned out to be. I've added a patch to the bug
report which adds URI support to the Epsilon Ant tasks... almost. I've
run into a problem when actually running it.
I prepared a simple example project with an Ant buildfile and a very
simple ECore model. This Ant buildfile uses several
epsilon.emf.loadModel tasks to load/prepare for storage the ECore,
GmfMap, GmfGraph and GmfTool models. The metamodels are loaded just fine
from the URI, but I can't quite load the ECore model itself. I've
described the issure more in detail in the bug report.
The .eol file is run, nevertheless: it actually complains that there was
an attempt to access the name property of an undefined object. I suspect
that should be the name of the first EPackage in my ECore model.
> It'd definitely be a nice addition. Thanks for the suggestion and for

No problem. The code looks pretty good in my opinon, though :-).

Antonio

I agree with you that it'd be better to simply use src and let the tasks

Yes, that was it. Works like a charm, thanks :-).

Bug-fixing at 1.30am! Very impressive :-)

It seems like a decent approach if it's not too hard to implement. I
think we may have some other code that does this.

Great, we'll integrate patches for both this enhancement and the
loadModel bug in the next week or so.

Great, we'll integrate patches for both this enhancement and the
loadModel bug in the next week or so.
