Support changing name and multiplicity of references [8]

[planger]

Maybe I missed the issue when looking through them, but currently, we it is not yet supported to change the name or the multiplicity of references. Labels of references support the direct edit feature too, so we may use it and do this similarly to the attribute name/type changes.

[CamilleLetavernier]

Yeah, it's not supported yet; I missed that too :)

Scope for now:
separate the label (multiplicity + name), change multiplicity (with drop down support), rename, no need to change layout for now

[planger]

change multiplicity (with drop down support)

Currently we only have the drop down support for the command palette, but not for rename inputs. It can quite easily be used for rename inputs too in a custom implementation. However, I think, it would be cool to have generic support for suggestions/auto-complete in the form of a drop down for renames as well.
We might need that in another project quite soon, so we might add generic support for that in GLSP in a bit.

I was thinking of something similar to the EType auto completion which awas recently contributed. Are you saying we might "generify that"?

[planger]

Ah, you mean #66 right?
I wasn't aware of that. Yes, I meant generifying that.

What exactly are the allowed multiplicities?
In the eclipse version for lower bound all numbers seem to be valid and for the upper bound also all numbers and -1 for * and -2 for unspecified.
Also should I invest time into #79 to generify the autocomplete?

[JonasHelming]

Let us not consider "-2" for now and treat "-1" as a synonym for "*"

Actually all other numbers are allowed therefore, I beleive the autcomplete case does not really fits here well. IMHO parsing [a..b] would be good enough
