Incompatibility with the original alogrithm
andelf opened this issue · comments
Cannot generated the same result as the original speedtest google/diff-match-patch.
Note:
- speedtest should return 2187 diffs, I use the python3 version
- this crate: 313, applied Semantic diff post proc
- dmp generates the same result
- diff_match_patch cannot generate the same result: 2177
Close. This should be a feature request for timeout and post proc options.
The Rust dissimilar::diff(text1, text2) is equivalent to the following from the python3 API:
dmp = diff_match_patch()
dmp.Diff_Timeout = 0.0
diffs = dmp.diff_main(text1, text2)
dmp.diff_cleanupSemantic(diffs)which both produce 313.
Without diff_cleanupSemantic the python3 implementation produces a low-quality diff. That's why you saw so many chunks come out of it (2187).
