diff-match-patch-line-and-unicode-aware-word v0.2.2
Diff Patch Merge Line and Unicode-Aware Word
What's this
An extension module that adds line-mode and word-mode diffs on google-diff-match-patch hosted as diff-patch-merge at NPM, originally by Neil Fraser, while respecting Unicode character sets and some general liquistic behaviors (e.g., hyphens and apostrophes are parts of words, but underscores are not) when identifying word breaks. This is based on karak's diff-match-patch-line-and-word(https://github.com/karak/diff-match-patch-line-and-word
Support for languages using marks (vowel marks above/below/inside consonants), left-to-right scripts, accented letters and similar items have been tested. PLEASE NOTE: Lines containing mixed scripts may give unexpected results and are considered unsupported. If you identify issues, please give complete examples indicating the two inputs, the incorrect results, the expected results and the name of the script used.
TypeScript is also supported.
