Slightly OT: Cleanup Problems view [message #650067]

Hello!

Maybe you can help me with a minor problem here:

I have a DeclarativeValidator which depends on some workspace state to do its work. When this state changes, errors from the last validation become stale. I could go into more detail but I don't think that's necessary for understanding my problem.

Basically, when this state changes, there can be some errors in the Problems view (you know, that tab with a list of all errors and warnings in your workspace) that are no longer valid. But because the validator does no longer touches the files which produce the errors (technically, they are no longer included into the build configuration), the error markers are not removed.

Long story short: What I want to achieve is that the Problems view get cleaned every time the validator is executed. Of course, syntax errors should not be removed but if I cannot separate them, it's not a big problem either if they disappear.

So:

1. How can I access the content of the Problems view?
2. If it is not obvious from the answer to question 1: Can I somehow separate errors produced by Xtext from errors produced by other components and maybe even syntax errors from validator errors?

Thanks in advance!
Florian Philipp

Hi,

as far as I know, the markers are attached to the IResource (obtaind from the editor). For marker creation etc. start digging at the org.eclipse.xtext.ui plugin (plugin.xml for the marker IDs) and the editor.validation package.

IResource provides a findMarkers and a deleteMarkers method.
