[Octave-bug-tracker] [bug #34852] incorrect column number on error messages

[Rik]

Update of bug #34852 (project octave):

                Priority:              5 - Normal => 3 - Low

Follow-up Comment #5:

Marking as low priority.  It seems better to print the column number because
often it will be correct and help localize debugging.  Occasionally, as in
this instance, it can be off.

Another thing that could be improved, however, is getting the column numbers
to add when there is more than one statement on a line.  For example,


clear all
sind z)
error: 'z' undefined near line 1 column 7


That's correct as 'z' appears in column 7.  Now,


a = 12345; sind (z)
error: 'z' undefined near line 1 column 18


which is also correct.  But as soon as you throw in operators things get off. 
In the following, z is at column 31 always but the the column is off in
different ways.


octave:5> a = [1 2] .* [3 4]; b = sind (z)
error: 'z' undefined near line 1 column 29
octave:5> a = 12345; sind (z)
error: 'z' undefined near line 1 column 18
octave:5> a = [1 2] * [3 4]'; b = sind (z)
error: 'z' undefined near line 1 column 28
