I have nothing against raster fonts for terminal applications, but I am 
surprised that support of X Logical Font Description may be considered 
as an improvement in comparison with an application relying on fontconfig.


I have never tried zutty, but I would expect something like (assuming 
fonts-liberation2 installed)


zutty -font LiberationMono -fontsize 24

However applications are usually more liberal concerning specifying 
vector fonts and use various fallbacks and substitutions.

To follow up on this:
  https://github.com/gryf/tabbedalt

$ mkdir -p ~/.urxvt/ext/
$ wget -O ~/.urxvt/ext/tabbedalt 
https://raw.githubusercontent.com/gryf/tabbedalt/master/tabbedalt
$ echo "URxvt.perl-ext: tabbedalt" >> .Xdefaults

Now you have tabs in urxvt.

It was meant tongue-in-cheek. OP's post prompted me to start digging into
urxvt and it is now my default terminal. :)

Modern terminals like Gnome-terminal, Konsole, alacritty, kitty and others
are essentially slapping a spruced-up UI on top of something that is 40+
years old. Tab-handling is one of the things that kitty does well that I
really like. But when it takes over ten times the memory for a single
instance compared to urxvt - I can forego the tab-handling and have
multiple windows instead. (Not looked yet if there is urxvt patches for
kitty style tab handling - which would be awesome if it exists.)

And as someone pointed out about the control character handling, there is
a security aspect to pay attention to as well. Xterm and Rxvt have both
been down this road for so long that they have that side of things
relatively well handled.

I've seen zutty because it was installed by default, but I have no idea
why it is installed by default. It does not strike me as the best choice
when both xterm and rxvt are available.

Almost certainly I was wrong. .Xresources should be read by xrdb, while

I'm not sure about rxvt-unicode, but the original rxvt definitely
worked that way.  This was part of the lightweight design of rxvt.
The author didn't want the bloat involved in reading the X resource
database, so he chose to read the source files directly.

According to :

  RESOURCES (available also as long-options)

  Note: 'rxvt --help' gives a list of all resources (long options)
  compiled into your version. If compiled with internal Xresources
  support (i.e. rxvt -h lists .Xdefaults) then rxvt accepts application
  defaults set in XAPPLOADDIR/Rxvt (compile-time defined: usually
  /usr/lib/X11/app-defaults/Rxvt) and resources set in ~/.Xdefaults,
  or ~/.Xresources if ~/.Xdefaults does not exist.


The corresponding section of the rxvt-unicode man page (in Debian 12)
is a bit confusing to me:

   You can set and change the resources using X11 tools like xrdb. Many
   distribution do also load settings from the ~/.Xresources file when X
   starts. urxvt will consult the following files/resources in order, with
   later settings overwriting earlier ones:

 1. app-defaults file in $XAPPLRESDIR
 2. $HOME/.Xdefaults
 3. RESOURCE_MANAGER property on root-window of screen 0
 4. SCREEN_RESOURCES property on root-window of the current screen
 5. $XENVIRONMENT file OR $HOME/.Xdefaults-
 6. resources specified via -xrm on the commandline

It says you can use xrdb, but then lists the places it looks, and that
list does not include xrdb(?).  I don't understand what this means.

I am unsure concerning real degree of danger, just a warning:

https://dgl.cx/2023/09/ansi-terminal-security

Additionally some terminals support C1 controls in UTF-8 encoded text,
which per this 2015 posting to oss-security is problematic. Some
terminals have the ability to turn this off, if they do not such as
Kitty I cannot recommend their use.

I pulled down rxvt-unicode and started looking at how to configure it up
so that it works more or less like kitty (which is what I normally use).

I was right about .Xresources that it is one of the files used for loading
settings into the X server, but urxvt looks at .Xdefaults instead. If one
puts something like the below into .Xdefaults in $HOME, it works with
Powerline and it does not look too terrible.

The original rxvt is no longer packaged in Debian, as far as I can see.
There's rxvt-unicode, which is what I use, which has most of the same
look and feel as rxvt, but is substantially larger.

Between xterm and rxvt-unicode you should have most of your "basic
no-frills terminal" needs met by one or the other.

Use 'xlsfonts' to see what fonts are available and use those names.
I can get it working with "zutty -font 12x24" and other numerically named
fonts. Trying with something like 'lucidasans-24' will make it dump core
however.

Maybe it respects what you tell it via .Xresources or what the file used
to be called, when you had to configure fonts by sitting with xfontsel and
try and work out what would look decent. The manual pages for xterm should
have enough clues for how to configure that - I have already forgotten all
that stuff as it no longer is required with the more modern terminal
emulators.

zutty is kind of only necessary when you want something *really*
lightweight and you do not need to worry about UTF-8. Just writing this
means a trip down memory lane and back to configuring CTWM on old Sun 5
workstations back in the 90's. If Debian still packages it, look for rxvt
instead, or use xterm. Both are well tried and well tested for when you

Zutty fonts - zutty always uses the same font and fontsize

[Richmond]

I am puzzled by the zutty terminal emulator. I have tried:

 1186  zutty -fontpath /usr/share/fonts/X11/ -fontsize 20
 1187  zutty -fontpath /usr/share/fonts/X11/ -font adobe
 1190  zutty -fontpath /usr/share/fonts/X11/misc/ -fontsize 20
 1191  zutty -fontpath /usr/share/fonts/X11/misc/ -fontsize 24
 1192  zutty -fontpath /usr/share/fonts/X11/misc/ -fontsize 12
 1193  zutty -font 9x20
 1198  zutty -fontsize 10x20
 1199  zutty -fontpath /usr/share/fonts/X11/misc/ -fontsize 10x20
 1200  zutty -font 10x20

I clearly have fonts:

find /usr/share/fonts -print|grep "x20"
/usr/share/fonts/X11/misc/10x20-ISO8859-9.pcf.gz
/usr/share/fonts/X11/misc/10x20-ISO8859-3.pcf.gz
