"Mark occurrences" service in IMP [message #511708]

Hi again,

now I am stuck with implementing the "mark occurrences" service. For some reason, the service is only called once, when the DSL file is opened. If I navigate around the file, the service is not called again to update the occurrence display. I am using IMP language meta-tooling 0.1.96 and IMP runtime 0.1.102 (downloaded from the update site). Does this functionality work in the release or should I check out the SVN version?

Hi there,

[Terribly sorry for not getting back to you sooner... my Thunderbird
install got mucked up and it took a while to get it back and healthy.]

This should work as you expect in the latest releases (e.g. the ones
available on the update site). In particular, I think it should be
working in 0.1.102, though there are newer versions available.

Is there anything in the Error Log that might indicate what's happening?

I upgraded to 0.1.103 yesterday and the problem persists.

No, there are no errors reported. I played with it today and noticed:
* If the mark occurrences service is called, the SourcePositionLocator is called for each of the returned nodes (and it returns correct answer). However, nothing is highlighted. Maybe it is just using colors black on white for highlighting matches?
* When I move the cursor around in the file, the mark occurrences service is not called.
* However, if I switch between different tabs in Eclipse (for example, click on the outline view and click back on the editor), then the mark occurrences service is called again.

Since I implemented the occurrence service from scratch, I am not very sure that I did everything correctly (maybe the runtime makes some additional assumptions that I do not fullfill).

The highlighting should be a fairly noticeable color (green-ish, IIRC).
But it certainly does sound as though either it's not getting as far as
applying the text attributes, or the attributes got messed up somehow.

Hmmm... that shouldn't be; needless to say, it should recompute the
occurrence set each time the text selection changes.

I'll take a look at the latest code and see what sort of behavior I get.

At any rate, sorry for the troubles, and thanks for the info!

Hello again,

I experimented a bit with the latest IMP version from the update site. When I select the "Mark Occurrences" button on the toolbar, the mark occurrences service is called and occurrences are highlighted in green. However, when I move the cursor, the markings do not move -- the service is not called again and the highlighting also stays. When I deselect-select the mark occurrences button, the service is called and the highlighting moves to cursor. Interestingly, when I click between editor windows, the highlighting is again performed, but old highlighting also remains present. See the screenshot below for example of this cumulative marking.

Does this service work normally for other people? Given that I used custom ANTLR-based parser to implement language, can this be problem in my implementation?
