difflib is a simple library written in Go for diffing two sequences of text.
To install, issue:
go get github.com/aryann/difflib
To start using difflib, create a new file in your workspace and import difflib:
import (
...
"fmt"
"github.com/aryann/difflib"
...
)
Then call either difflib.Diff
or difflib.HTMLDiff
:
fmt.Println(difflib.HTMLDiff([]string{"one", "two", "three"}, []string{"two", "four", "three"}))
If you'd like more control over the output, see how the function
HTMLDiff
relies on Diff
in difflib.go.
There is a demo application in the difflib_demo directory. To run it,
navigate to your $GOPATH
and run:
go run src/github.com/aryann/difflib/difflib_server/difflib_demo.go <file-1> <file-2>
Where <file-1>
and <file-2>
are two text files you'd like to
diff. The demo will launch a web server that will contain a table of
the diff results.
