This was also going to go out after i posted the
display/displaytb patch. But anyway, let's see what
you all think.
I propose the following stylistic changes to traceback
printing:
1. If there is no function name for a given level
in the traceback, just omit the ", in ?" at the
end of the line.
2. If a given level of the traceback is in a method,
instead of just printing the method name, print
the class and the method name.
3. Instead of beginning each line with:
File "foo.py", line 5
print the line first and drop the quotes:
Line 5 of foo.py
In the common interactive case that the file
is a typed-in string, the current printout is
File "<stdin>", line 1
and the following is easier to read in my opinion:
Line 1 of <stdin>
Here is an example:
>>> class Spam:
... def eggs(self):
... return self.ham
...
>>> s = Spam()
>>> s.eggs()
Traceback (innermost last):
File "<stdin>", line 1, in ?
File "<stdin>", line 3, in eggs
AttributeError: ham
With the suggested changes, this would print as
Traceback (innermost last):
Line 1 of <stdin>
Line 3 of <stdin>, in Spam.eggs
AttributeError: ham
