如何在 Eclipse CDT 的搜索视图中更改引用的突出显示颜色？

Note: this is different from standard match highlight color .

Answer 1

I found out two easy solutions to this problem:

1) Create a new file and add those lines (extension of the file needs to be .epf):

file_export_version=3.0
/instance/org.eclipse.ui.workbench/org.eclipse.cdt.ui.ColoredLabels.match_highlight=128,0,128 

You might change the color value to match your theme

Then go to File -> Import -> General -> Preferences

Browse to the newly created file and click the Finish button

2) Go to [workspace-location]/.metadata/.plugins/org.eclipse.core.runtime/.settings

Edit org.eclipse.ui.workbench.prefs file and add the line

org.eclipse.cdt.ui.ColoredLabels.match_highlight=128,0,128

Answer 2

It seems that these colours are not editable and are therefore hard coded in a way that (clearly!) does not work well with a dark theme.

This is the relevant part from the org.eclipse.cdt.ui/plugin.xml :

  <colorDefinition
        id="org.eclipse.cdt.ui.ColoredLabels.match_highlight"
        isEditable="false"
        label="%Dummy.label"
        value="206, 204, 247">
  </colorDefinition>

A small change to the plugin.xml allows the colour to be editable:

  <colorDefinition
        categoryId="org.eclipse.cdt.ui.presentation"
        id="org.eclipse.cdt.ui.ColoredLabels.match_highlight"
        isEditable="true"
        label="Match Highlight"
        value="206, 204, 247">
  </colorDefinition>

And then you can edit the background colour and fix your problem.

This is a known issue in CDT ( Bug 468206 ), contributions welcome.

Found a workaround that works for me. With eclipse closed:

• unpack <eclipse installation folder>\\plugins\\org.eclipse.cdt.ui_6.3.0.201802261533.jar
• edit plugin.xml and change the color to your taste
• put this file back into the jar
• delete <eclipse installation folder>\\configuration\\org.eclipse.core.runtime\\.mainData.1
• start eclipse
