6At this point, I have no longer the time nor the interest to work on go-difflib. I apologize for the inconvenience.

10Go-difflib is a partial port of python 3 difflib package. Its main goal
11was to make unified and context diff available in pure Go, mostly for
12testing purposes.
13
14The following class and functions (and related tests) have be ported:
15
16* `SequenceMatcher`
17* `unified_diff()`
18* `context_diff()`

20## Installation
21
22```bash
23$ go get github.com/pmezard/go-difflib/difflib
24```
25
26### Quick Start
27
28Diffs are configured with Unified (or ContextDiff) structures, and can
29be output to an io.Writer or returned as a string.
30
31```Go
32diff := difflib.UnifiedDiff{
33 A: difflib.SplitLines("foo\nbar\n"),
34 B: difflib.SplitLines("foo\nbaz\n"),
35 FromFile: "Original",
36 ToFile: "Current",
37 Context: 3,
38}
39text, _ := difflib.GetUnifiedDiffString(diff)
40fmt.Printf(text)
41```
42
43would output:
44
45```
46--- Original
47+++ Current
48@@ -1,3 +1,3 @@
49 foo
50-bar
51+baz
