Diffy
Diff, Match and Patch implementation for Erlang.
Introduction
Diffy is an erlang implementation of the Diff Match and Patch library for plain text. The implementation uses binaries throughout and is utf-8 aware.
Example
1> diffy:diff(<<"fruit flies like a banana">>, <<"fruit flies eat a banana">>)
[{equal,<<"fruit flies ">>},
{delete,<<"like">>},
{insert,<<"eat">>},
{equal,<<" a banana">>}]TODO
- cleanup_semantic(diffs()) -> diffs()
- make_patch(Text1, Text2) -> patches(), make_patch(unicode_binary(), diffs()) -> patches(), make_patch(Diffs) -> patches()
- match(Text, Pattern, Loc)
