Tim Peters 81b9251d59 Mostly in SequenceMatcher.{__chain_b, find_longest_match}:
This now does a dynamic analysis of which elements are so frequently
repeated as to constitute noise.  The primary benefit is an enormous
speedup in find_longest_match, as the innermost loop can have factors
of 100s less potential matches to worry about, in cases where the
sequences have many duplicate elements.  In effect, this zooms in on
sequences of non-ubiquitous elements now.

While I like what I've seen of the effects so far, I still consider
this experimental.  Please give it a try!

Guido van Rossum 77f6a65eb0 Add the 'bool' type and its values 'False' and 'True', as described in
PEP 285.  Everything described in the PEP is here, and there is even
some documentation.  I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison.  I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.

Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.

Tim Peters 496563a514 Remove some now-obsolete generator future statements.
I left the email pkg alone; I'm not sure how Barry would like to handle
that.

Tim Peters 527e64fd68 Whitespace normalization. 2001-10-04 05:36:56 +00:00
Tim Peters 8a9c284437 Make difflib.ndiff() and difflib.Differ.compare() generators. This
restores the 2.1 ability of Tools/scripts/ndiff.py to start producing
output before the entire comparison is complete.

Tim Peters 5e824c37d3 SF patch #445412 extract ndiff functionality to difflib, from
David Goodger.

Tim Peters 754ba589b7 Improve accuracy. In the .tex file, note the new "% BUG:" comments: an
extra backslash is getting displayed in the generated HTML.

Fred Drake f1da6287fc Fix a few small typos in the docstrings.
get_close_matches():  Do not use %-interpolation for strings when
    concatenation is more efficient.

Tim Peters 9ae2148ada Moved SequenceMatcher from ndiff into new std library module difflib.py.
Guido told me to do this <wink>.
Greatly expanded docstrings, and fleshed out with examples.
New std test.
Added new get_close_matches() function for ESR.
Needs docs, but LaTeXification of the module docstring is all it needs.
