    dest

    Type: function(string, string): string

    This function take an argument (a relative file path and the base path). The source file path is exactly equivalent to path.relative(vinylFile.path, vinylFile.base). It SHOULD return the file path for the dest file path. The return value is used as a target of comparison.

    You can easily rename by using rename.

    pathResolver

    Type: function(string, string): string

    Default: changed.relativeResolver

    This function take 2 arguments (a dependent file path, the depended file path captured by matcher) and MUST return a file path for the depending file. If omitted, it takes a related file path from the dependent file.

    If file extensions is omitted, you can complement the file extensions by the function.

    comparator

    Type: function(VinylFile, VinylFile): boolean

    Default: changed.compareByMtime

    This function take 2 arguments (a depending file and the dependent file) and it MUST return true when the depending is newer than the dependent file. If omitted, it compare by the both mtime.
