Subject: How to get DISPLAY of emacsclient?
Date: Fri, 25 Nov 2022 22:17:54 +0700 [thread overview]
Message-ID: <tlqmb3$ic$1@ciao.gmane.io> (raw)
Hi,
Is it possible to get display of an emacsclient process? I mean either
--display option argument or the DISPLAY environment variable namely for
the client.
Unfortunately the value of following expression is the DISPLAY
environment of the server process
emacsclient --eval '(getenv "DISPLAY")'
I admit, it should work in most cases, but it is not robust:
DISPLAY= emacs --daemon --display :0
causes empty string returned by `getenv'. In general, emacsclient's
display is not necessary the same as the server's one. If I have got it
correctly, the value is passed from client to server and there is a
local "display" variable in server.el hidden from evaluated expression.
The context of the question is the following. Org-capture allows to
create notes in non-distracting way (by setting :immediate-finish t
property of the capture template). The idea is to save text currently
selected in some application (either PRIMARY or CLIPBOARD) using a
global window manager shortcut invoking
emacsclient --eval '(org-capture nil "x")'
There is a pitfall. Emacs daemon has no frame at startup, so selection
is inaccessible:
emacsclient --eval "(org-get-x-clipboard 'PRIMARY)"
returns nil (it is merely a convenient way to call `gui-get-selection').
A workaround is to call `server-select-display', but to do so it is
necessary to know display. That is why I am asking how to obtain display
of emacsclient.
