[imp-dev] ILanguageActionContributor

["Jurgen Vinju" <Jurgen.Vinju@xxxxxx>]

Hi guys,

I'm implementing language features here at CWI for
ASF+SDF and we'd love to have nested menu's, and also the possibility
to add toolbar items and such.
Currently, we are using
ILanguageActionContributor which can contribute a flat list of actions
to the editor popup menu. What we need (at least) is to be able
to add arbitrarily nested menus. See also https://bugs.eclipse.org/bugs/show_bug.cgi?id=230786

[intermezzo]
we are replacing the old Meta-Environment way of declaring nested
menu's as ATerms by a plugin.xml schema for nested menu's. A menu is
defined
by a nested XML _expression_ with leaf tags that show the final menu
options and what needs to be done for them (e.g. a reference to an
IAction class,
or in our case a reference to a ToolBus process).
[end]

What is the best way to go:
  a) I adapt the code in Universal Editor and ILanguageContributor such
that ILanguageContributors can create submenus, and show the patches to
you (or commit right away)
 
b) I incorporate the XML schema for nested menus into IMP and adapt the
Universal Editor to implement this, and show the patches to you

Or something in between, or something else. I'm open to
suggestions. I consider this a nice and simple project on which we can
try-out our remote collaboration skills ;-)

Cheers,

Jurgen
