Ich möchte eine "To-Do" -Liste für mein Hintergrundbild erstellen. Ich hatte gehofft, eine Textdatei schreiben, speichern und den Hintergrund jedes Mal aktualisieren zu können, wenn ich eine Datei bearbeite. Ist das möglich?

Antworten:
Das folgende Skript überwacht eine Textdatei, die Sie bearbeiten können. Wenn die Datei geändert wird, wird eine neue Ebene über Ihrem Hintergrundbild mit dem Text der Datei erstellt.
Sie können definieren:
Das Skript verwendet Imagemagick. Möglicherweise müssen Sie es zuerst installieren:
sudo apt-get install imagemagick
Dann:
walltext.py
.original.jpg
Führen Sie das Skript mit dem folgenden Befehl aus:
python3 /path/to/walltext.py
Beginnen Sie nun mit der Bearbeitung Ihrer Textdatei. Alle fünf Sekunden wird das Hintergrundbild bei Bedarf aktualisiert (nachdem Sie die Änderungen gespeichert haben):
1 Spalte, maximal 30 Zeilen pro Spalte
2 Spalten, maximal 20 Zeilen pro Spalte
3 Spalten, maximal 10 Zeilen pro Spalte

Ich habe den obigen Code geändert, um stündlich zufällige Anführungszeichen auf das Hintergrundbild zu setzen. Viel Spaß :) http://forraskod.blogspot.hu/2016/01/linux-hatterkep-veletlenszeru.html
