[9fans] Show/edit acme snarf buffer

[Brian Vito]

Using either/both acme under Plan 9 and/or Mac OS X via plan9port, is
there a "file" that can be opened in acme that displays the current
contents of the acme snarf buffer? If so, is there a way to have that
window automatically update when the snarf buffer changes? Basically,
I'm wondering if there is a way to duplicate the functionality that
was generally present in old Macintosh text editors under the show
clipboard command. Finally, if this functionality is available, would
it be possible that by editing the snarf buffer window to edit the
contents of the snarf buffer itself (as was possible in Nisus's old
editor QUED/M)?

Under Plan 9 there's /dev/snarf.

/dev/snarf

Not quite automatically. You can write a program which polls /dev/snarf
using fstat(2); qid.vers will be updated when the file is written to.

Just as with any acme window, the underlying file will only change
when you click Put.  Again if you're willing to do some programming,
you could monitor changes in the window using the acme event file
and do the Put automatically.

it doesn't have the properties the op requested.  a read at eof doesn't
hang until the contents of the file have changed.

If manual update is acceptable he could add "Get" to the tag line.

I guess a simple polling program could be written for acme, but many
uses of the selection while you're editing the text would end up
overwriting your edit.

Thank you -- these are useful suggestions. Is there an equivalent to /
dev/snarf when using plan9port under Mac OS X?
