Is hypertext supported?

Config:

$ ps -p $$ -o args,ppid
COMMAND                        PPID
bash                          47293
$ ps -p 47293 -o args
COMMAND
/usr/bin/xfce4-terminal
$ bash --version
GNU bash, version 5.1.16(1)-release (x86_64-pc-linux-gnu)

This displays correctly but not clickable.

$ cat ./debug.sh
format_link="\e]8;;%s\e\\%s\e]8;;\e\\n"

help() {
    printf "%s\n" "Also see:"
    printf "$format_link" "http://example.com/foo" "foo"
    printf "$format_link" "http://example.com/bar" "bar"
    exit 0
}

help
$ ./debug.sh
Also see:
foo
bar

I’m somewhat blindly relying on this.

xfce4-terminal : xfce4-terminal Staged for v1.2 release on 2022-11-07

We are on:

xfce4-terminal --version
xfce4-terminal 1.0.4 (Xfce 4.18)

So am I.

Try a supported terminal:

From the link you posted.

This one is according to the link.

$ emacs --version
GNU Emacs 28.2

I get:

$ cat ./debug.sh
format_link="\e]8;;%s\e\\%s\e]8;;\e\\n"

help() {
    printf "%s\n" "Also see:"
    printf "$format_link" "http://example.com/foo" "foo"
    printf "$format_link" "http://example.com/bar" "bar"
    printf '\e]8;;http://example.com\e\\This is a link\e]8;;\e\\\n'  # github example
    exit 0
}

help
$ ./debug.sh
Also see:
e]8;;http://example.com/fooe\fooe]8;;e
e]8;;http://example.com/bare\bare]8;;e
e]8;;http://example.come\This is a linke]8;;e\

I tried it in emacs(client) in vterm and it crashes emacs!!! Which emacs terminal is that?

Kitty - nope (left)

xfce4-terminal-git - works!! but have to control and click. (centre).
