Reserved words and metaclass'property name [message #9374]

Hi list,

I'm new to epsilon and would like to thanks for the great work done !

I have a problem using egl : a metaclass named Interface owns a property
named "operation" and when writing an egl program the word appears as a
reserved word so I can't make use of it. Is there a way to avoid this ?
In some other languages they use the ~ to avoid this so I can write
mymetaclass.~oepration.

Is there something like this or another way to get out of this ?

Also, how does one can make a distributable product embedding its epsilon
programs ?
I don't really see how I can use the extensions to distribute easily the
eol programs, any doc coming ? =)

I'd like to point Acceleo here and its Module feature which make it easy
to create standalone applications or plugins, www.acceleo.org, it's open
source and eclipse based, if it can use.

Thanks !

Yes. You can enclose the reserved word in "" (e.g. mymetaclass."operation")

Do you mean an Eclipse or a non-Eclipse based product?

That sounds interesting in principle. Do you have a link to the
documentation of this feature so that I can have a look into it?

Hi,

Thanks !!

About acceleo, the doc is in french, but I can describe quickly how it
works.

You first create a generator project (acceleo perspective), then a
template and a chain. You then add parameters to the chain (=ant task but
can only call templates or other chains). Finally you export your project
as an acceleo module, plugin or standalone application (which is an
eclipse product with the generator inside plus whatever you want, you feed
him with parameters in an ini file and run it to get generated files)

It works pretty well ! There are samples too, and if you need some help to
test I can.

Here is all free doc http://acceleo.org/pages/introduction/en

Thanks !

If you want I've made a ecore2acceleo module plugin which make use of this
feature.
It's a plugin which helps you creating chains to launch the generation.

https://sourceforge.net/project/platformdownload.php?group_i d=250817

You'll need acceleo for this test.

Put it in your plugins directory, relauch, create an emf project and
model, then new->acceleo->Module launcher, Here you'll get all modules
availlable.
There should be three, all available thanks to the ecore2acceleo plugin.

Briefly I explain: step 1 create a gengenerator.properties file, step2
create a generator.properties and the last one create acceleo templates
for all eclasses of the metamodel.

This module has been made very easily using the export feature of acceleo.

When clicking Next in the new->acceleo->module launcher->ecore2acceleo
step1, the parameters of the chain are fields of the window and need to be
set by the user.

Hope this help in your try.

Hi Stephane,

Thanks for the pointers; this looks really interesting but unfortunately
there is currently nothing like this in Epsilon.

Having said this, you can still use Epsilon programmatically from your
standalone Java application (see
http://dev.eclipse.org/viewsvn/index.cgi/trunk/examples/org. eclipse.epsilon.examples.standalone/?root=Modeling_EPSILON
for examples of using different Epsilon languages without any Eclipse
dependencies), and as part of other Eclipse plugins (see
http://dev.eclipse.org/viewsvn/index.cgi/trunk/plugins/org.e clipse.epsilon.productivity/?root=Modeling_EPSILON
where EGL transformations are executed on ECore models via a
contribution to the Eclipse context menu).

Please let me know if you face any problems integrating Epsilon to your
application and I'll be happy to help!

Cheers,
Dimitris

Thanks Stephane! I'll set-up Acceleo and give it a try shortly. Do you
have a specific use-case for such functionality in Epsilon or is it
mainly a nice-to-have feature?

Cheers,
Dimitris

Thanks !

If you can just tell me how can I pass parameters to an eol program ?

So I can make the output path parametrable :)

Thanks !!
