changing font and font size in terminal emacs-27.2

changing font and font size in terminal emacs-27.2

[Sivaram Neelakantan]

How do I change the font and size when I run emacs in a terminal i.e
emacs-nox?  I'm running emacs-27.2 in wsl and for the GUI emacs I can
configure the font like so

;; GNU Emacs 27.2 (build 4, x86_64-pc-linux-gnu, GTK+ Version 3.24.20,
;; cairo version 1.16.0) of 2021-08-06
   
(message "setting font type and size")
 (add-to-list 'default-frame-alist
                       '(font . "Cascadia Mono-13"))
;;(set-frame-font "-outline-DejaVu Sans Mono-normal-r-normal-normal-*-*-130-130-c-*-iso8859-1")
;;(set-frame-font "-outline-Cascadia Mono-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1")

this same init file when read by emacs-nox doesn't seem to apply the
font.  C-u C-x = in terminal emacs doesn't show the font type.  The
manual section doesn't mention anything about terminal based emacs and
addresses 4 methods for the GUI emacs only.

I think you have to set the terminal's font for that. As far as I know,
Emacs has no way to change the terminal's font.

If you are using xterm then set the font in ~/.Xdefaults and/or
~/.Xresources. For example, I have

! Set font and size: 
XTerm*faceName: DejaVu Sans Mono Book
!XTerm*faceName: Monospace
XTerm*faceSize: 10

For other settings, search the Internet for .Xdefaults .Xresources. The
particular file depends on the Linux flavor. I have both files
identical.

Hope this helps.

Thanks, I did have that and it seems to have no effect;  Been trying
various stuff and at this point if I can get the emacs terminal font
at 12pt or above I'd be happy. :-)

Using your settings

XTerm*faceName: Cascadia Mono
XTerm*faceSize: 12

in my ~/.Xdefaults, I can get launch "emacs -nw" in an xterm with size
12 font.

I notice that you also have "emacs.font: DejaVu Sans Mono-12" in your
~/.Xdefaults. I wonder if this is interfering when you run emacs in a
terminal? Have your tried commenting out "emacs.font: DejaVu Sans
Mono-12"? Also you seem to be using emacs -nox, have you tried emacs -nw
instead? It may be the latter will work without commenting out the
reference to the emacs font. Try both.


Best wishes,

So far, we have not seen any indication that Sivaram is using Xterm.
On the contrary, since WSL was mentioned, there is a high probability
of the Windows terminal.

@Sivaram In any case, you should find out which terminal emulator you
are using, and then how to customize the fonts it uses. Neither Emacs
nor any other terminal-based application has any say over that.

Ok, but I got the impression that Sivaram was using a .Xdefaults file.

Yes and was expecting MS terminal to read it.  It doesn't (obviously)
and xterm does, which was driving me batty.

Yes and No!  I use windows terminal and it didn't work in it; when I
launch xterm and then tried it, it worked.  See earlier post in thread.

Correct.  I was trying out changes to .xresources in Windows terminal
which does not read it all.  Once I launch xterm, it did.  I didn't
work out the right sequence of issues being seen.  Your point about
the terminal cleared it up for me.

Great that the problem is cleared up.

After a series of uncoordinated addled testing, I think I sussed out
the following settings.

Removed font stuff from emacs.xresources and kept only the Xterm font spec
Tested in xterm and confirmed that it works
it works for both Emacs-nox and Emacs -nw(what's the difference?)

So, thanks for that.

I omitted to mention that I run WSL Ubuntu 20.04 with GWSL(X server)
and use MS terminal as the initial terminal.  MS terminal has its own
setting for font and size which seem to be overriding whatever I was
doing with the unrelated .Xresources tinkering. Rather, MS terminal
was not readiing anything that I was doing to the .X resource files.
Only when I launch xterm from within MS terminal was it being read.
Coupled with the fact, sometimes I forget to do `xrdb -load`, I was
getting inconsistent results (hence addled).

It took a combination of @Colin's and @Yuri's messages to clear things
up. 

Many thanks to both.

Yes, I think I figured out the issue.  And thanks for the config
files, it is useful.

A bit off topic, but ...

I use WSL, and I run the MATE window manager.  I can use GUI emacs
as well as any other GUI.

I use the Linux VT for Emacs but rumors has it I can run
emacs-nox in xterm but also launch the the GUI Emacs _from_
xterm ...

I can run GUI emacs from a Linux terminal command prompt in WSL.

True that.  And I did mention that I could configure the GUI Emacs
version but having issues with terminal emacs.

What I was looking for, was the means to change various emacs -nw,
Emacs-nox parameters in just the terminal.  And still looking for a
theme or a set of fonts/faces that would just assume 16 bit colour and
give a decent terminal interface emacs a bit of colour/fonts/faces.

I've pretty much given up on .X* configuration changes and decided to
look for configuration options in 1 place i.e .emacs

For GUI, I've gotten it down to

(when (window-system) ;; looks like this is deprecated
   (setq default-frame-alist
         '((top . 24) (left . 1) (width . 172) (height . 38)
           (background-color . "DarkSlateGray")
	       (foreground-color . "Wheat")
           (cursor-color . "Red")
	       (horizontal-scroll-bars . nil)
	       (vertical-scroll-bars . nil)
           (font . "-outline-Cascadia Mono-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1")
         ))
   (setq initial-frame-alist
         '((top . 24) (left . 1) (width . 172) (height . 38)))
   (set-frame-font "-outline-Cascadia
   Mono-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1"))

And now want to set terminal Emacs along similar lines.
