Hints for a "code fragment" eclipse editor

you could also call this thing "scrapbook" which seems to exist for
the java plug in (File -> New -> Other -> Java -> Java Run/Debug ->
Scrapbook Page). that has a neat execute selection button, some
features (such as auto completion), but lacks others (such as syntax
highlighting)...

so maybe a solution would be to have a ScalaSnippetEditor (that
extends somewhat the JavaSnippetEditor)... there are some problems to
solve, e.g. i would need to run the snippets on the current VM not a
separate one, as i would like to be able to programmatically access
the current eclipse project.

Yes, something along these lines would be wonderful ... it'd be great
if you had the time to work on it.

Cheers,

i will do my best... however i will definitely need help from you
guys as this whole eclipse monster is still a little bit too big for
me. i'm very slowly getting through the whole class tree structure
(of eclipse, but then at some point also lampion and scala).

i'll let you know when i have something useful...
