This adds a new
DiffUnified()method which takes a[]Diffslice and formats it in the "unified diff" format. The[]Diffslice does not necessarily need to be a linewise diff.The implementation deals gracefully with missing newlines at the end of either side, as well as empty inputs on either side.
The method accepts two optional arguments:
UnifiedLabels()for setting the labels for the two inputs andUnifiedContextLines()for setting the number of context lines printed.Example usage:
A convenience method,
Unified(), takes two string inputs and returns the unified diff.Fixes: #124
