JET1 Editor for EMF Codegen template extensions [message #426809]

Following
http://www.ibm.com/developerworks/library/os-eclipse-emfmeta model/index.html
I am extending the way some of my code is generated.

Is there any editor to make editing JET**1** easier?

Is there any way to extend EMF Codegen templates using JET2 .. other than
a separate generation followed by JMerge? ( as in
http://dev.eclipse.org/newslists/news.eclipse.modeling.m2t/m sg00640.html,
I know I can use JET2 templates on .ecore files as outlined in the JET2
help )

Are there any plans to migrate Codegen to use JET2?

Thanks

The editor that's in the JET2 project works.

There this bugzilla:
<https://bugs.eclipse.org/bugs/show_bug.cgi?id=152374>

https://bugs.eclipse.org/bugs/show_bug.cgi?id=152374

But realistically, the drive to do this is poor given it's in the end a
big no-op and that it introduces problematic build dependencies...

Thanks once again Ed,

I have set the JET2 editor up to work with my JET1 templates.

However I obviously have problems with <%@ include
file="foo2.javajetinc"%> since the JET Editor tells me it cannot find
them. JET2 would give me that modularity I know, but I just wondered if
there are any solutions to some other minor wrinkles that I have using
JET2 Editor on JET1 source.

This is not much of a worry since the java is generated as expected.

Editing an include file is obviously problematic - it's just a text
insertion, and the including context changes what is syntactically correct
or what is not (i.e. you could only really edit it in JET 1 "in place").
However if I define a variable in the include ( see below ) and reference
it in the including javajet file, it still shows it as an error,
eventhough in the generated java it is not.

Am I doing anything wrong or is that the limit of JET1 support?

Project/templates/foo.javajet:

<%@ jet package="deleteMe" class="foo"%>
<%@ include file="foo2.javajetinc"%>
<% foo = "new";
reallyNotThere = "stuff";%>

Project/templates/foo2.javajetinc:

<% String foo="stuff"; %>

Did you configure it's preferences to expect JET1 syntax?

Yes, it kind of sucks.

The errors are generated by compiling the template and mapping the
errors back. I assume you've done that? Perhaps is worth reporting in
a bugzilla if something that should be working isn't...

I've added a bugzilla ( seems a bit harsh but... )
https://bugs.eclipse.org/bugs/show_bug.cgi?id=262139

One last (hopefully) question my ***old*** JET1 project has a .project
file with the following JET nature;

<nature>org.eclipse.emf.codegen.jet.IJETNature</nature>

and a Builder as follows:

<buildCommand>
<name>org.eclipse.ui.externaltools.ExternalToolBuilder</name >
<triggers>full,incremental,</triggers>
<arguments>
<dictionary>
<key>LaunchConfigHandle</key>
<value> <project>/.externalToolBuilders/org.eclipse.em f.codegen.JETBuilder.launch </value>
</dictionary>
</arguments>
</buildCommand>

Any reason why I shouldn't convert those to use the new JET builder and
JET nature?

<nature>org.eclipse.jet.jet2Nature</nature>

and the new JET builder ( setting the compliance level to JET1 ? )

<buildCommand>
<name>org.eclipse.jet.builder</name>
<arguments>
</arguments>
</buildCommand>

Thanks

Sorry the JET1 builder should have been;

<buildCommand>
<name>org.eclipse.emf.codegen.JETBuilder</name>
<arguments>
</arguments>
</buildCommand>

JF,

You could try it. Probably that will be fine...

I did some more work on this and put my notes on the bug report
https://bugs.eclipse.org/bugs/show_bug.cgi?id=262139

Basically I can't get the M2T JETEditor to work with includes at all well.

Do you have any tips? How do you edit the codegen templates?

Otherwise I guess its time to port to JET2...

JF,

I find that if I change the JET compiler preferences, because they're
global, it messes up the JET project itself. So I just tolerate the few
JET1 errors at the top. Our templates use include, but that doesn't
seem to cause any problems, so I'm not sure what to suggest...

Thanks Ed,

So you leave the Window->Peferences->JET Complier stuff as it was and
change the settings to JET1 on a per project basis?

What is the project in CVS that you use to edit the templates .. maybe if
I downloaded that it would help.

Thanks...

It seems that some of my problems are caused by the fact that my include
files had a directive on the first line. If I just add an empty line at
the top my problems opening editors go away so far...

JF,

It's been a long time since I fiddled with settings for this. I didn't
know there were any project level ones but now that you ask I realize I
have to add the JET1 nature for those; silly me. But since my project
doesn't actually depend on new JET, I don't really want to add that
nature. If I change the global settings, the org.eclipse.jet project
ends up with build errors; I've not had the time to track down why...

In case anyone else has problems with this later;
I have my JET1 stuff working with the current JET Editor plugin, bar the
moaning about not finding includes, which however it still finds and
generates with

JF & Ed:

I've taken a look at these problems and have made some fixes. They will be
available in this weeks M and I builds. For the record, here are the defects
I've fixed:
