Summary: doctest: allow custom matchers for testing if got==want
Initial Comment:
To determine the success of a doctest example,
doctest compares the
actual output to the expected output. The test
succeeds if the two
match exactly.
This patch gives the user the ability to supply a
custom "matcher"
function, which will be used instead of string equality
to test
whether the test succeeds. This function should take
two string
parameters, "got" and "want", which will contain the
actual and
expected output, respectively; and it should return
True if they
should be considered to match (i.e., test succeeds),
and False if they
should not (i.e., test fails).
Two sample matcher functions are provided, as well:
- match_ignoring_whitespace returns true if the
actual output
and expected output are equal, ignoring
differences in amount
of whitespace (eg 2 spaces vs 1).
- match_ignoring_trailing_blanklines returns true if
the actual
output and expected output are equal, once any
trailing blank
lines are discarded. This can be useful with the
END_WITH_DEDENT
option, suggested in patch #932933 [1]
The patch was made avainst revision 1.33 of
doctest.py.

Please resubmit the patch using unified diffs. You might
just as well include test cases and documentation right away.

If this patch looks good, I'd be happy to write a patch for
the docs & test cases.
