> What's the reason again that memmap only works with binary files?
There are no separate "text files" and "binary files". All files are
binary, some just contain text that in some cases represents an array of
Memmap views also text files as binary. It returns you an array
representing the *character data* in the file.
> Could the functionality be extended to text files as well?
In principle, yes. But this would need special parsing of the text in the
memmap. Doing this right would be considerably more work than just
representing the binary data. Also, I doubt that this would be very
useful: representing large amounts of data as text is not efficient. I
also think few people have interest in this feature.
