* Issue #7585: use tab between components in unified and context diff headers.R. David Murray2010-04-121-16/+19
| | | | | | | | | | | | Instead of spaces between the filename and date (or whatever the string is that follows the filename, if any) use tabs. This is what the unix 'diff' command does, for example, and difflib was intended to follow the 'standard' way of doing diffs. This improves compatibility with patch tools. The docs and examples are also changed to recommended that the date format used be the ISO 8601 format, which is what modern diff tools emit by default. Patch by Anatoly Techtonik.

* SequenceMatcher.get_matching_blocks(): This now guarantees thatTim Peters2006-06-141-8/+34
| | | | | | | | | | | adjacent triples in the result list describe non-adjacent matching blocks. That's _nice_ to have, and Guido said he wanted it. Not a bugfix candidate: Guido or not ;-), this changes visible endcase semantics (note that some tests had to change), and nothing about this was documented before. Since it was working as designed, and behavior was consistent with the docs, it wasn't "a bug".
* get_matching_blocks(): rewrote code & comments so they match; addedTim Peters2006-06-131-14/+14
| | | | | | more comments about why it's this way at all; and removed what looked like needless expense (sorting (i, j, k) triples directly should give exactly the same order as sorting (i, (i, j, k)) pairs).

* Mostly in SequenceMatcher.{__chain_b, find_longest_match}:Tim Peters2002-04-291-18/+55
| | | | | | | | | | | | 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!
* Add the 'bool' type and its values 'False' and 'True', as described inGuido van Rossum2002-04-031-7/+7
| | | | | | | | | | | | | 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.

* Moved SequenceMatcher from ndiff into new std library module difflib.py.Tim Peters2001-02-101-0/+781
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: ----------------------------------------------------------------------
