Re: Eclipse Plugin working much better!

Although I think I may have read that Eclipse in general is slower on Linux...

I'm thinking about trying Eclipse, but before I do I'd like to get an idea about how well it works remotely over a cable internet connection. I sometimes work from home using Linux on both ends and ssh -X over Comcast cable. Has anyone used Eclipse with that sort of setup? If so, how fast does it respond? Thanks.

Can't speak to how it works on X specifically, but I have essentially this configuration (using a Comcast cable modem), and do most of my Eclipse work using Windows' Remote Desktop.  It's not *stellar*, but I've found it entirely workable.  (And one would hope that Linux at both ends is likely to be more efficient than Windows at both ends...)

OK - I'm having quite a bunch of problems with the current nightlies, one is
http://lampsvn.epfl.ch/trac/scala/ticket/1669.

Another one is that I quite often get a java.util.ConcurrentModificationException

And after seeing that Exception, files will open without any syntax highlighting,

You never saw any of these?

Keep on doing great work! In terms of features, the Eclipse plugin is
really great, and very useful when it works. However, it is small and
insignificant features like this one that made me switch back to
emacs:

http://lampsvn.epfl.ch/trac/scala/ticket/1733

I really hope I'll be able to come back to Eclipse (I still use it as
a debugger and for toy projects) at some point. 2.8.0 maybe? ;-)

Me too, but we share at least one wall :)

I am wondering whether the plugin developers actually eat their own dog
food. I am experiencing these and other rather random issues such as cut
and paste failing while working on the compiler project but also while
browsing the plugin source.

No.  At least not in my personal projects. 

However, I do see more issues when 'dogfooding' the plugin.  I attribute a lot of that to a few things:
  * Excessive use of traits
  * special "somewhat working" optimizations in the eclipse plugin for excessive use of traits
  * dogfooding process is freaking out eclipse.  I lean away from that, as it doesn't quite make sense. 
I'm hoping with time we can begin to fix some of these issues

Try a  project that isn't using virtual classes or the cake pattern and you'll see the plugin is able to handle it pretty well.  That said, hopefully in the future the plugin will handle all types of scala projects.

Err ... you tried the workaround that I mention in the comments on that bug?

I'll have a fix for these two committed very soon.

I very definitely do ... updates to the plugin are invariably
committed to SVN using a plugin which incorporates those changes.

I see all the issues you're seeing but pretty clearly less frequently
than you do. It'd be interesting to get to the bottom of exactly why
that is: platform? resources?

Miles

Mac OS, -Xmx1500m or so. I have the feeling that the plugin is very
fragile when not treated with caution. The copy and paste bug, for
example, happens most often when I do some quick
cut-to-the-end-of-line's ala emacs. The concurrent mod exception seems
to happen more often when I do two double clicks on a file in a row,
sometimes on the first try the file does not open, or when I quickly
open two files one after the other. It's only a feeling, though, I have
not measurable data for this :)

Yes, and it works! The other reasons for switching to emacs are my
personal lack of time (although it is very rewarding to see bug
reports investigated so quickly!), and that syntax highlighting
doesn't work way too often. I know the compiler code is complex and
not that usual, so I don't expect these bugs to be fixed very soon. In
the end, I am more efficient with something that works all the time
for simple things (emacs), than a very advanced IDE that sometimes
does not do even simple things. Please don't take this as criticizing
your work, you are doing a great job, and I wish I had more time to
help (through bug reports)!

cheers,
iulian

OK, these should all be fixed now ... #1669 by a patch from Ben
Hutchison, thanks!

Amazing, many thanks guys! I'll install the new version and see how it goes.
