 - `drawFileList`: show a file list before the diff: `true` or `false`, default is `true`
-- `diffStyle`: show differences level in each line: `word` or `char`, default is `word`
+- `srcPrefix`: add a prefix to all source (before changes) filepaths, default is `''`

 - `diffMaxLineLength`: number of characters in a diff line after which a file diff is deemed as too big and not

 - `diffTooBigMessage`: function allowing to customize the message in case of file diff too big (if `diffMaxChanges` or
-  `diffMaxLineLength` is set)
+  `diffMaxLineLength` is set). Will be given a file index as a number and should return a string.
