Functions

function applyPatch

applyPatch: (
    source: string,
    patch: string | ParsedDiff | [ParsedDiff],
    options?: ApplyPatchOptions
) => string | false;

Applies a unified diff patch.
Parameter patch
May be a string diff or the output from the parsePatch() or structuredPatch() methods.
Returns
A string containing new version of provided data. false when failed

function applyPatches

applyPatches: (
    patch: string | ParsedDiff[],
    options: ApplyPatchesOptions
) => void;

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:
1. 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. 2. 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. 3. Once all patches have been applied or an error occurs, the options.complete(err) callback is made.

function canonicalize

canonicalize: (obj: any, stack: any[], replacementStack: any[]) => any;
