Package Exports

what-the-diff

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (what-the-diff) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Parse unified diffs with JavaScript

Installation

what-the-diff is available via npm

npm install what-the-diff

Usage

let {parse} = require('what-the-diff')

var str = `diff --git file.txt file.txt
index 83db48f..bf269f4 100644
--- file.txt
+++ file.txt
@@ -1,3 +1,3 @@
line1
-line2
+new line
line3`

parse(diffStr)

// returns
  {
    oldPath: 'file.txt',
    newPath: 'file.txt',
    oldMode: '100644',
    newMode: '100644',
    status: 'modified',
    hunks: [
      {
        oldStartLine: 1,
        oldLineCount: 3,
        newStartLine: 1,
        newLineCount: 3,
        lines: [
          ' line1',
          '-line2',
          '+new line',
          ' line3'
        ]
      }
    ]
  }

If the diff includes a similarity index line (from a detected copy or rename), the similarity property will be set, and will be a number.
