Bug ID: 430055
Summary: Bash escape sequences visible in the output of
qalculate
Product: cantor
Version: 20.08
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: qualculate-backend
Assignee: cantor-b...@kde.org
Reporter: joshua.hough...@yandex.ru
Target Milestone: ---
Created attachment 133895

Screenshot of qualculate and cantor side by side
SUMMARY
Qalculate now applies colours to it's output. Cantor however fails to parse the
bash escape sequences and therefore outputs garbase
STEPS TO REPRODUCE
1. Create a thing with the qalculate backend
2. Run this mathematical expression ((-2)^3.3)
3. You'll see the following garbage in the output
(−[0;36m2[0m)^[0;36m3.3[0m ≈ [0;36m−[0m[0;36m5.789188237[0m −
[0;36m7.968134023[0m[0;33mi[0m
4. Run this mathematical expression integrate(asin(x))
5. You'll see the following garbage in the output
integrate(arcsin([0;33m[3mx[23m[0m)) = [0;33m[3mx[23m[0m ×
arcsin([0;33m[3mx[23m[0m) + √([0;36m1[0m −
[0;33m[3mx[23m[0m^[0;36m2[0m) + [0;33m[3mC[23m[0m
OBSERVED RESULT
See screenshot attached. Look at the output from cantor
EXPECTED RESULT
See screenshot attached. Look at the top left terminal

ADDITIONAL INFORMATION
I was going to look into this issue myself but when i tried to compile and run
cantor i couldn't https://bugs.kde.org/show_bug.cgi?id=430045. I did eventually
manage to get it to start but i feel i should probably be getting on with other
things now.
I have tested the following versions of cantor and can confirm this is an issue
on all three.
