Bug ID: 463012
Summary: Folding Marker displayed even when folding region too
small to fold
Classification: Frameworks and Libraries

OS: Linux
Status: REPORTED

SUMMARY
During character based folding, fold start markers are identified and displayed
for small one-line folding regions, however, they don't actually fold those
regions.
STEPS TO REPRODUCE
An example in a c-style language
void myFunction(){
}
This will display a code fold marker (the small triangle icon on the left hand
boarder) however, will not actually fold the function.
This probably doesn't come up too much in c-style languages because you
probably wouldn't have an empty function. However in python I would expect the
following is quite common:
def myFunction():
''' Some documentation about my function
'''
lines of function that do things ...
The doc string in between the two sets of triple quotes " ''' " will display a
code folding marker. In addition a code folding marker will be displayed for
the "def myFunction ():" line also. However, the folding marker on the two line
doc string will not actually fold that section. More over, trying to click the
code fold marker for the doc string will fold the whole body of the function.
This can cause a fair amount of confusion about what is going on as the user
would likely expect the lower line of the doc string the " ''' " to fold up.
Choosing not to fold small one-line regions like this isn't at all a problem.
However, preferably in this case the code fold marker for the region wouldn't
be displayed as that region can't actually be folded and a believe that is the
desired behaviour.
SOFTWARE/OS VERSIONS
This behaviour was experienced on Ubuntu 22, with Kate version 23.03.70.
However, I would expect similar behaviour on any platform.
