Re: [9fans] spaces in file/dir names? (and acme)?

[Axel Belinfante <Axel.Belinfante@cs.utwente.nl>]

To solve my particular case at hand (playing mp3 files made available
via u9fs, where I don't want to do any special work at the remote end),
I resorted to writing (hacking) what I've named so far 'substfs',
a file server that is supposed to sit between 'the user'
(usually mount) and the remote u9fs, and does do file name substitution.
Apart from the file server that it should work on, it is given
two edit programs (filter scripts) that (should) do the remote->local
and local->remote conversions. The edit programs could then
be 'tr '' '' `{unicode whatever}' (and the reverse).
(actually, I use something like: cat|tcs -f 8859-1| tr ' ' @
 where @ is one of the special space characters mentioned in this thread
 which number I don't recall right now).

So far it seems to work -- even though the editing is not yet done
for all message types, and mememory management is a joke.
I also haven't tried yet what happens if I mount its /srv/bla
file in two different places and try to access it 'simultaniously'.
I built by glueing together bits and pieces taken from u9fs, 9pcon,
lib9p and probably some other places.
When it is slightly more complete (and there is interest?)
I will probably post it to 9fans or it make available via the web.
Writing it has been quite instructive in getting more insight in
the 9p2000 protocol.

Axel.
