'symbols break most editors

I'd love to use 'symbols for interned string-liek constants.  However, TextMate flips everything to string after what it thinks is the opening '.I have to carefully watch it and terminate the line with //', if needed.  I have yet to see a non-Emacs editor to understand symbols. Anybody with a TextMate fix for it?  Why don't we change it to :symbols in 2.8 or some other non-pairing prefix?  :)
Cheers,Alexy

I've asked for the special syntax to be deprecated, or preferably compiler inlined. As it works today, every time you use the special syntax, a lock is acquired, a map lookup performed using a String key, and then either the map value is returned or a new Symbol is constructed. Every single time. So you better not use it for faster comparison, because it is in fact slower.

Nils -- so it confirms my hunch that using "just" strings is easier than symbols!  Text editors will be happy and speed will improve...  So much for 'em 'eymbols.  (Now am compulsively matching open-close quotes.)

I became sufficiently annoyed with the single quote thing to learn the
textmate bundle syntax well enough to fix that and a few other things.
What I didn't learn is how exactly those changes are stored and what the
simplest way to give them to someone else is. Everything you need looks
to be in the file I found here:

Library/Application Support/TextMate/Bundles/Scala.tmbundle/Syntaxes/Scala.tmDelta

A copy of which I have placed at:

http://www.improving.org/scala/Scala.tmDelta

...but no tech support beyond that, that's everything I know.

Paul -- awesome. Which original Scala bundle do you use? Last time I
touched those bundles was when I grabbed your megabundle off github
and anointed the first one as Library/Application
Support/TextMate/Bundles/Scala.tmbundle. Did you add the
Scala.tmDelta to that one?

[Since then, some new things appeared, such as
http://smallcultfollowing.com/nikolog/2009/06/06/new-scala-textmate-bundle/,
but they, as well as some from that megabundle, don't work for me.
Macromates doesn't list the official Scala bundle among
http://svn.textmate.org/trunk/Bundles/.]

Cheers,
Alexy

Vim with the syntax highlighting files from http://
lorenzod8n.wordpress.com/2008/01/11/getting-scala-syntax-hightlighting-to-
work-in-vim/ works just fine. I think you need to write some TextMate
syntax highlighting files. It should be able to handle them.

(TextMate can handle LISP, can't it? LISP does exactly the same thing
with quotes.)

Re: 'symbols break most editors
Here's a reasonable good jEdit 4.3 (beta) Scala edit mode. It handles symbols and chars correctly. What I couldn't teach it to is to recognize Scala identifiers. It doesn't have a rule for that, and the break chars stuff it uses isn't powerful enough (Scala would require a negative look-behind to handle break chars properly).
