Bug ID: 418519
Summary: Konsole not processing ANSI codes for next line,
previous line
Product: konsole
Version: 19.12.2
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: emulation
Assignee: konsole-de...@kde.org
Reporter: j...@joeysbytes.net
Target Milestone: ---
SUMMARY
ANSI code CSI n E means to go down n lines, then go to the beginning of that
line.
ANSI code CSI n F means to go up n lines, then go to the beginning of that
line.
Konsole is not handling these ANSI codes properly (or at all). I have tested
with Gnome terminal and xterm, and they work as expected, so I believe this is
a Konsole-specific issue.
STEPS TO REPRODUCE
Run this 2 line bash script:
clear;echo -e "\n\n\n\n\n";
echo -e "Second line\e[1FFirst line\e[2EThird Line\n\n"
OBSERVED RESULT
Second lineFirst lineThird Line
EXPECTED RESULT
First line
Second line
Third Line
