## API
-* `JsDiff.diffChars(oldStr, newStr[, callback])` - diffs two blocks of text, comparing character by character.
+* `JsDiff.diffChars(oldStr, newStr[, options])` - diffs two blocks of text, comparing character by character.
+
+ Returns a list of change objects (See below).
+
+* `JsDiff.diffWords(oldStr, newStr[, options])` - diffs two blocks of text, comparing word by word, ignoring whitespace.
Returns a list of change objects (See below).
-* `JsDiff.diffWords(oldStr, newStr[, callback])` - diffs two blocks of text, comparing word by word, ignoring whitespace.
+* `JsDiff.diffWordsWithSpace(oldStr, newStr[, options])` - diffs two blocks of text, comparing word by word, treating whitespace as significant.
Returns a list of change objects (See below).
-* `JsDiff.diffWordsWithSpace(oldStr, newStr[, callback])` - diffs two blocks of text, comparing word by word, treating whitespace as significant.
+* `JsDiff.diffLines(oldStr, newStr[, options])` - diffs two blocks of text, comparing line by line.
+
+ Options
+ * `ignoreWhitespace`: `true` to ignore leading and trailing whitespace. This is the same as `diffTrimmedLines`
+ * `newlineIsToken`: `true` to treat newline characters as separate tokens. This allows for changes to the newline structure to occur independently of the line content and to be treated as such. In general this is the more human friendly form of `diffLines` and `diffLines` is better suited for patches and other computer friendly output.

Just like JsDiff.createTwoFilesPatch, but with oldFileName being equal to newFileName.
-* `JsDiff.applyPatch(oldStr, diffStr)` - applies a unified diff patch.
- Return a string containing new version of provided data.
+* `JsDiff.structuredPatch(oldFileName, newFileName, oldStr, newStr, oldHeader, newHeader, options)` - returns an object with an array of hunk objects.
+
+ This method is similar to createTwoFilesPatch, but returns a data structure
+ suitable for further processing. Parameters are the same as createTwoFilesPatch. The data structure returned may look like this:
+
+ ```js
+ {
+ oldFileName: 'oldfile', newFileName: 'newfile',
+ oldHeader: 'header1', newHeader: 'header2',
+ hunks: [{
+ oldStart: 1, oldLines: 3, newStart: 1, newLines: 3,
+ lines: [' line2', ' line3', '-line4', '+line5', '\\ No newline at end of file'],
+ }]
+ }
+ ```
+
+* `JsDiff.applyPatch(source, patch[, options])` - applies a unified diff patch.
+
+ Return a string containing new version of provided data. `patch` may be a string diff or the output from the `parsePatch` or `structuredPatch` methods.
+
+ The optional `options` object may have the following keys:
+
+ - `fuzzFactor`: Number of lines that are allowed to differ before rejecting a patch. Defaults to 0.
+ - `compareLine(lineNumber, line, operation, patchContent)`: Callback used to compare to given lines to determine if they should be considered equal when patching. Defaults to strict equality but may be overriden to provide fuzzier comparison. Should return false if the lines should be rejected.
+
+* `JsDiff.applyPatches(patch, options)` - applies one or more patches.
+
+ This method will iterate over the contents of the patch and apply to data provided through callbacks. The general flow for each patch index is:
+
+ - `options.loadFile(index, callback)` is called. The caller should then load the contents of the file and then pass that to the `callback(err, data)` callback. Passing an `err` will terminate further patch execution.
+ - `options.patched(index, content, callback)` is called once the patch has been applied. `content` will be the return value from `applyPatch`. When it's ready, the caller should call `callback(err)` callback. Passing an `err` will terminate further patch execution.
+
+ Once all patches have been applied or an error occurs, the `options.complete(err)` callback is made.
+
+* `JsDiff.parsePatch(diffStr)` - Parses a patch into structured data
+
+ Return a JSON object representation of the a patch, suitable for use with the `applyPatch` method. This parses to the same structure returned by `JsDiff.structuredPatch`.
* `convertChangesToXML(changes)` - converts a list of changes to a serialized XML format
-All methods above which accept the optional callback method will run in sync mode when that parameter is omitted and in async mode when supplied. This allows for larger diffs without blocking the event loop.
