diff 
Module github.com/pkg/diff can be used to create, modify, and print diffs.
The top level package, diff, contains convenience functions for the most common uses.
The subpackages provide very fine-grained control over every aspect:
myerscreates diffs using the Myers diff algorithm.editcontains the core diff data types.ctxtprovides tools to reduce the amount of context in a diff.writeprovides routines to write diffs in standard formats.

Contributing
Contributions are welcome. However, I am not always fast to respond. I apologize for any sadness or frustration that that causes.
Useful background reading about diffs:
- Neil Fraser's website
- Myers diff paper
- Guido Van Rossum's reverse engineering of the unified diff format
- The If Works blog entries about diff algorithms and implementations
This module has not yet reached v1.0; the API is not yet settled (issue #18).

Overview ¶
Package diff contains high level routines that generate a textual diff.
It is implemented in terms of the other packages in this module. If you want fine-grained control, want to inspect a diff programmatically, want to provide a context for cancellation, need to diff gigantic files that don't fit in memory, or want to diff unusual things, use the lower level packages.

Functions ¶
func Slices ¶
Slices diffs slices a and b and writes the result to w. It uses fmt.Print to print the elements of a and b. It uses reflect.DeepEqual to compare elements of a and b. It uses aName and bName as the names of a and b in the output.
func Text ¶
Text diffs a and b and writes the result to w. It treats a and b as text, and splits their contents into lines using bufio.ScanLines. aFile and bFile are filenames to use in the output.
a and b each may be nil or may have type string, []byte, or io.Reader. If nil, the text is read from the filename.
