Diese Frage ist eine Fortsetzung der früherenFragelinebackgroundin dem es geändert wurde, um in wenigen Codezeilen neben der Farbe auch die Hintergrundfarbe einzuschließen . MWE ist unten angegeben:

Dieses MWE [außer dem Hintergrundfarbschlüssel] wurde bereitgestellt von@moewe. Wenn ich jetzt beide Tasten verwende: linebackgroundcolorund backgroundcolor, funktioniert die Farboption backgroundcolornicht mehr. Ich habe versucht, den Autor des Pakets zu kontaktieren, aber es ist mir nicht gelungen. Ich bitte um Vorschläge zur Problemumgehung.
Antwort1
Die Hintergrundfarbe funktioniert im Prinzip einwandfrei. Das Problem besteht darin, dass das von Ihnen verwendete Hervorhebungsmakro nicht nur die hervorzuhebenden Zeilen füllt, sondern auch alle anderen Zeilen mit Weiß füllt und somit den grauen Hintergrund überdeckt.
Als Workaround können Sie dies \btLstHLwie im folgenden Beispiel anpassen:

\usepackage{listings, pgffor}
