Add aegisub.file_name() to get the file name of the subtitles file

Browse source 
If called during a macro processing or validation function when the
subtitles have a valid file name (i.e. they've been saved and are not
Untitled), this returns the name of the file, without the path. If
called at any other time, it returns nil.
