Re: Proposal: emacsclient --readonly

[Rüdiger Sonderfeld]

Hello,
what happened to this patch?  It would be very useful to me right now.

There should probably be a way to add functions to `commands' (in server-
process-filter) though.  With this patch it could be done by adding an "--
eval" statement to the args.  But there should probably be a clean way.

I'm currently attempting to write an info(1) like program which loads the info 
page in the running Emacs session.  I need this to support the "doc" comment 
in `inferior-octave'.  With this patch it could be done without a lot of 
hacks.

Regards,
Rüdiger
