Description Miwako Tokugawa

Build Identifier: 

Hi.
Could you please improve the help doc on “Marker Support” (org.eclipse.ui.ide.markerSupport)?
To begin with, I am having a problem with "problemFilter"
I checked out the unit tests in org.eclipse.ui.tets but didn’t get much insight from it either.



Reproducible: Always

Steps to Reproduce:
To reproduce
1.	check out CDT head
2.	Create a helloc in runtime eclipse that will cause gcc to give warning.  Build to make sure you can see the warning in Problems view
3.	Add the following to org.eclipse.cdt.managedbuilder.gnu.ui/plugin.xml
<extension point="org.eclipse.ui.ide.markerSupport">
<problemFilter
enabled="true"
scope="ON_ANY"
onDescription="ABC" (I tried with “ABC” and “!ABC” here)
name="filter1"
(I tried with and without “severity="WARNING" “ here)
id="filter1">
<selectedType markerId="org.eclipse.core.resources.problemmarker"/>
</problemFilter>
</extension>
to org.eclipse.cdt.managedbuilder.gnu.ui/plugin.xml
4.	no warning is shown in problems view no matter what you do
a) "ABC" and no "severity"
b) "!ABC" and no "severity"
c) "ABC" and "severity=WARNING"
d) "!ABC" and "severity=WARNING"
According to “Marker Support” on help.eclipse.org, this should cause only the warning string that contains “ABC”  in the problem view.. right? Or am I missing something?

A similar case is this.
I take it that the following should display problem markers that contains the string “MY” in the description field in the “MY View” view. Well, it doesn’t. MY View displays all problem markers, whether their description field contains "MY" or not.

<!—define a new marker type -->        
<extension point="org.eclipse.core.resources.markers"
        id="com.intel.compiler.cdt.managedbuilder.ui.MYMarkerType">
        <super type="org.eclipse.core.resources.problemmarker"/>
        <super type="org.eclipse.core.resources.textmarker"/>
        <attribute name="description"/>
        <persistent value="true"/>
</extension>
<!-- MYMarkerType is subset of problemmarker that contains "MY" in the description string -->
<extension point="org.eclipse.ui.ide.markerSupport">
        <problemFilter
                enabled="true"
                scope="ON_ANY"
                onDescription="MY"
                name="filter"
                id="com.intel.compiler.cdt.manageduilbder.ui.MYFilter">^M
                <selectedType markerId="com.intel.compiler.cdt.managedbuilder.ui.MYMarkerType"/>^M
	</problemFilter>
	<!-- Associate MYMarkersView with MYMarkerGenerato -->
	<!-- markerContentGenerator id is passed to the MYMarkersView constructor -->
        <markerContentGenerator
        id="com.intel.compiler.cdt.managedbuilder.ui.MYMarkerGenerator"
        name="dum">
        <markerTypeReference id="com.intel.compiler.cdt.managedbuilder.ui.MYMarkerType"/>
        <markerTypeReference id="org.eclipse.core.resources.problemmarker"/>
        <markerTypeReference id="org.eclipse.core.resources.marker"/>
        <markerFieldReference id="org.eclipse.ui.ide.descriptionField"/>
        </markerContentGenerator>
        </extension>
</extension>

<!-- define a new view -->
<extension point="org.eclipse.ui.views">
        <view class="com.intel.compiler.cdt.managedbuilder.ui.MYMarkersView"
        id="com.intel.compiler.cdt.managedbuilder.ui.MYMarker"
        name="MY View">
        </view>
</extension>

Also, the comment in MarkerContentGenerator.java says
 // Honour the deprecated problemFilters

Is problemFilters deprecated? What should I be using instead if it is?

(In reply to comment #2)
Please never mind this comment. This does seem to be documented (though I googled and still can't get to it as of now)

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
