How can a Vim script know if we're running without an X connection?
Of course, some cases are obvious, such as
if has('unix') && !has('x11')
meaning we're on Unix with no X11 support compiled-in.
But what about an X-enabled Vim running in console mode, either with the -X
command-line switch, or in a terminal with no access to an X server?
For instance, I might want to map the following
:map <S-F5> cc<C-R>+
in my vimrc, to replace the current line with the clipboard. However that
mapping should not be enabled if we have no access to the clipboard. So I wrap
it in
if has("clipboard") && (&term != "linux")
:map <S-F5> cc<C-R>+
:imap <S-F5> <C-O>cc<C-R>+
endif
which takes care of two cases:
- running with no clipboard support compiled-in
- running in the (non-X) linux console (aka /dev/tty)
It doesn't take care, however, of the case when an X-enabled Vim was started
as "vim -X" in an xterm. Is there a way to check for that in vimscript?
Best regards,
Tony.
