Re: Read-whole-buffer command and cursor

["T. V. Raman" <ramantv@xxxxxxxxxxx>]

A few clarifications on why  I never bothered implementing
indexing in emacspeak 
1) Bart's assertion that it was because of lack of two way
communication between emacs and the speech server is not
accurate.
You can have the speech server spit out acknowledgements and
catch these with a process-filter function in emacs 
--in fact I had tried this in earlier versions of emacspeak.

However, the  the timing issue still remains --things get
harder to debug.
gnudoit may well resolve those issues because 
rather than parsing the output of the tcl process in emacs
and blocking for the index, you would have tcl signalling
emacs  with the index, which should prevent some of the
timing woes.


Also,  getting back the last index spoken 
is only half the story --you then need to map this to the
appropriate text chunk in the buffer you're reading.
This is again non-trivial because emacspeak does quite a few
transformations to the text before shipping it off in 
chunks to the speech server. So 
you would at best create some approximation of where you
stopped speech --and spend the rest of the time answering
email explaining why it  was out of sync.
Finally, Matt -- slavishly sticking to what is part of
default emacs is not a productive way to make progress 
if Gary implements a gnudoit based solution --that's well
and good--
gnuserv can always be packaged up.


To return to Gary's message below:
"it should be easy to ..."
Sure --it is doable --doing it might take less time than
talking about it:-)
However,  be aware that though cut 0 might be easy the final
polishing up will take time 
--and it's a judgement call as to how much worth the trouble
it is.
The reason I never wrote it is that I found it not worth the
trouble --this is not to say that it may not be worth 
someone else's while based on time availability and personal
need.
