rewrite functions

rewrite functions

[Yair Friedman (Jerusalem)]

Hi all,

The variable mm-file-name-rewrite-functions is a List of functions used
for rewriting file names of MIME parts.

Currently it works only on the filename part.  However, one might want
to apply some of the functions such as 'upper' on the full path.  On the
other hand, some of the functions such as 'delete-whitespace' are better
not applied on the path.

Should another variable be created?  Any other options?

All of the saving functions generally ignore the supplied path -- they
usually refer to local paths on the sender's machine, so they aren't
very useful.  Not ignoring the path is also a security risk -- if
you're reading mail as root, and you get something that's called
"/etc/passwd", the MUA would be doing you a disservice if it gave you
that as the default name to save.

So, I think the current method is fine.

Oh, but I need rewrite functions for the paths Gnus supplies - mostly
for the dumb applications that don't understand the "x:/path/file.ext"
syntax in mm-display-external, and possibly in mm-save-part.

Ah, right.  `mm-file-name-rewrite-functions' is only used when saving
files, I think -- not when giving them to external viewers.

In what way would you rewrite "x:/path/file.ext", and wouldn't you
have to rewrite the names differently for different viewer?

Would you want to do this only for Excel, or do you want to apply this
transformation to all viewers?

Currently I need to rewrite it to "x:\\path\\file.ext" as some
applications (excel) don't understand the former syntax.  To achieve
this, I need to apply convert-standard-filename from w32-fns.el which
convert the splashes, and replaces forbidden characters with others.

I'd like this transformation on all viewers.  This is why
mm-file-name-rewrite-functions looked like a natural candidate in the
first place.

I've just added `mm-path-name-rewrite-functions'.  It's the new
variable to control this.

Thanks a lot!
