Hello IntelliJ IDEA Community!
I am currently working on a custom plugin for IntelliJ IDEA, and I'm looking to implement coverage highlighting similar to what's available in the IDE itself. Specifically, I want to add colored bars in the gutter to indicate which lines of code have been covered during testing.
I've explored using a custom
LineMarkerProvider and a custom
Icon to represent the colored bars, but I'm having difficulty achieving the exact appearance used by IntelliJ IDEA for coverage highlighting.
If anyone has experience implementing coverage highlighting in their own plugins or has insights into the styling and customization of gutter icons for this purpose, I would greatly appreciate your guidance.
Any tips, examples, or documentation references would be incredibly helpful. Thank you in advance for your assistance!
