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!	24 years ago
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.	24 years ago
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.	24 years ago
Tim Peters	527e64fd68	Whitespace normalization.	25 years ago
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.	25 years ago
Tim Peters	5e824c37d3	SF patch #445412 extract ndiff functionality to difflib, from David Goodger.	25 years ago
Tim Peters	754ba589b7	Improve accuracy. In the .tex file, note the new "% BUG:" comments: an extra backslash is getting displayed in the generated HTML.	25 years ago
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.	25 years ago
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. \CVS: ----------------------------------------------------------------------	25 years ago
