Separator issues between GUI and Terminal Emacs

[dbordak]

Things can get kinda screwy if you have both a GUI and a Terminal emacs running on the same server.

I'm on doom-emacs (on top of emacs 27 compiled from source on ubuntu 18.04 bionic), and currently the line is just not rendered (a plain line probably with modeline background color) in TUI emacs when I use emacsclient (the server has been started by the GUI emacsen invocation before).

Do you have any idea about how a fallback could be implemented to handle this ? Maybe a hook could be used to make relevant calls to display-graphic-p ?

[gagbo]

Auto answer : the fallback mechanism was already implemented, just not used in the bundled separators. This has been the objective of #111

How I can enable the behavior provided in #111? I'm still having this issue:

TUI

GUI

Environment

Env	Version
Emacs	25.2.2
telephone-line	20200516.2102
Linux Kernel	4.15.0
Linux Distro	Mint 19.1

It has been merged, weird that you still have the issue :(

I've used my fork for long enough that I may have not correctly upstreamed my changes but it looked fine on the diff. i.e you should have a > as separator

[dbordak]

@ryukinix There's still a separator rendered, even though it's obviously incorrect, so this looks like you're using a font without powerline support. If you're using terminal Emacs, you need a font with powerline support.

@dbordak nice catch! You are totally right. That indeed fixed my problem! I was using the Hack font without being patched for powerline, so downloading from https://github.com/powerline/fonts/blob/master/Hack and replacing it did the trick. Now worked flawless!

Thank you, @dbordak and @gagbo ! :D
