Which Eiffel compiler are you using with EiffelWeb?

[Jocelyn Fiat]

Hi all,

Could you tell us which Eiffel compiler you are using to work with EiffelWeb?

The reason is just to avoid supporting old compiler if this is not necessary.

Currently I think EiffelWeb supports 17.05, 17.01, 16.05 (maybe even older compilers).

Until now, we have been careful about supporting at least the last 2 releases of EiffelStudio for the EiffelWeb Framework git repository.

With the introduction of capabilities with EiffelStudio 17.01, among other benefits, for each library, it allows to have a single .ecf (instead of two previously, for void-safe and non void-safe).

So currently, in the git repository, supporting version prior to 17.01 is a (little) burden, as it prevents EiffelWeb from using ECF capabilities, and as a side effect, it requires an extra step when including EiffelWeb in EiffelStudio delivery.

Note, the version included in EiffelStudio (or via iron) is adapted to benefit from latest improvements on EiffelStudio compiler, including ecf new capabilities. 

Thanks for any answer, you can also send me directly the answer to jf...@eiffel.com

Kind regards,

-- Jocelyn

We are using 16.05. We will shortly be moving to 17.05.

Ok let me know when it is acceptable to remove support for compiler before 17.01 .

Note there is no urgency for now, this question is many to anticipate changes in EiffelWeb source organisation.

Hi Jocelyn,

Thanks very much for asking!!!

We are using 17.05.

We currently do not have official releases for customers.

So for us you can leave the support for older versions as proposed.

Regards, Paul.

Happy to use the latest, only laziness sometimes prevents me from
switching early.

All the best,

Hi all,

So as far, from those answers, and a others we got by messages, it seems to be safe to drop support for Eiffel compilers before 17.01.

I mean, as soon as Colin confirmed they made the switch to either 17.01, or 17.05.

Thanks,

Just found two problematic issues in 17.01 and 17.05:

1. Execution parameters are not saved, so after restart of studio,
you're back to square one.

2. It no longer detects changes made to files outside the IDE, this
used to work perfectly.

[Jocelyn Fiat]

Hi Berend,

Can you remind me which platform/OS you are using with EiffelStudio.

I guess your .ecf file does not have any uuid="..." in the "<system .." tag.

Can you try to set one?

Also, are you using gexace? if yes, could you send me the .xace file, and more important the generated .ecf file if you have any.

For the point first point (not remembering the execution parameters), I suspected a bug when no uuid is provided.

For the second point, could it be a change in gexace that produce different .ecf files?
Are you using the gexace delivered with EiffelStudio, or you got it from Gobo-Eiffel delivery/source code?

Regards,

Somehow the problem has fixed itself, can't repeat it. The only thing
I can remember doing at some point was exporting parameters, and
importing them, not sure that's the cause, but parameters stick now.

I have uuids. Perhaps the file change issue is gone too, not sure. It
works when starting from fresh. Just about to write a new app, so I'll
see if things work.

I'm no longer using gexace, so only pure .ecf files.

[Jocelyn Fiat]

Ok glad to hear problem is fixed.

By the way, the issue with ecf without any uuid is fixed for next release.

About file change issue, if ever you still have the issue, please let Eiffel Software knows about it.

Note that for libraries that are marked as readonly, EiffelStudio won't try to detect file change. 

Otherwise the detection is based on the date of the file.

So it would be surprising this is failing on ubuntu (as I guess this is your primary platform).

Regards,

And it's back: note that Studio actually shows the refreshed file, but
it does not pick this up when compiling, so that's why you see the
error at the bottom. I need to use "Find Added Classes & Recompile" to
fix this.

[Emmanuel Stapf]

When changes are not picked up, it is most likely because the class is part of a read-only library (the default). In this case the compiler never compiles the class again. To force a compilation you can:

- make the library editable

- press Alt+F8 to force a recompile of all changed/new classes.

What's a read-only library? I poked around in the schema definition
but don't see any place where I can change that when I use a <library>
in my .ecf.

Ah, answering myself, I poked around in the UI and saw it there, it's
the readonly attribute.

That'll be it.

[Emmanuel Stapf]

The easiest is to do it from the project settings window. In the ECF add the readonly="false" attribute to a library node.

17.05

[Jocelyn Fiat]

Hi all,

It seems all users of EiffelWeb git repository are using at least 17.05 .

So in the coming days, we will remove support for older version, and keep as requirement version 17.05 or newer.

Thanks for your answers,

-- Jocelyn

[Jocelyn Fiat]

The changes were done a time ago.
