bug#28801: 26.0.90; Document after-make-frame-functions, focus-in-hook in Startup Summary node

Kaushal Modi
 
Hello Eli,

I had a long conversation with you in May 2016[1] about understanding the best place/hook for graphics related setup (like fonts) in emacs config, when running emacsclient.

As I later learned in that conversation, neither after-init-hook nor emacs-startup-hook were the right place for that. after-make-frame-functions was also not good unless the frame is selected (which is not the case in emacsclient/daemon). So focus-in-hook turned out to be the best place were I can check if a certain font was available etc.

I have read through (elisp) Startup Summary, but it does not reference after-make-frame-functions and its caveat with emacsclient. It also does not reference focus-in-hook.

I believe having that information in that section will be very valuable to other users using emacsclient in GUI frame.

Copying Rob on this as he had a similar question he asked me off the list.

These hooks are not related to startup, so I don't see why they should
be described in that section.  They would be out of place there, and
the resulting discoverability will be low.

There is a separate section that describes all of the hooks, and I
usually look there when I need some hook, but don't know which one to
use.

There could be a place for a new section in the Emacs manual regarding
customizations for people who start Emacs as a daemon.  Patches to
that effect are welcome from people who have experience using and
customizing Emacs in that mode.
