Hi Guix developers,
When using mate-terminal version 1.12.1 (the default graphical terminal provided in Trisquel 8), Guix commands
that print hyperlinks to the terminal (such as `guix describe` and `guix show`)
print a mangled \x1b]8;; OSC character. I haven't tested the mate-terminal
package provided by Guix though, so this bug may only be visible to Trisquel users
of the Guix package manager relying on their host distribution's default terminal soon
after installing Guix.
On a related note, the procedure supports-hyperlinks in module (guix ui) checks the
environment variable INSIDE_EMACS to prevent hyperlink mangling when using Emacs.
Perhaps this procedure could be edited to solve this bug.

I have tested with "guix environment --ad-hoc mater-terminal" on
foreign distro (Debian) and I do not see an issue.
So it probably comes from the Trisquel default configuration.

Does "INSIDE_EMACS=1 guix describe" fix the issue?
All the best,

So, it is not a bug. ;-)

Put in your configuration "export INSIDE_EMACS=1". :-)
Does the environment variable NO_OSC appears to you more meaningful
than INSIDE_EMACS?
Where do you think this should be documented? Which part of the manual?
All the best,
simon

It is more meaningful, but this terminal does interpret other operating system codes,
like OSC 12 for changing the cursor color. NO_OSC_8 would be specific to hyperlinks.

The theory is that terminals should ignore OSC codes that they do not
support. Good’ol xterm, for instance, silently ignores those hyperlink
codes, whereas GNOME Terminal interprets them nicely.
So I would say that this is a bug in this version of mate-terminal, or
perhaps in the libvte version it’s using?
I’ve just tried mate-terminal 1.22.0 on vte 0.58.3 from Guix, and it
silently ignores those codes.
Thanks,
Ludo’.

Yes, the bug is in libvte 0.28.2 as distributed with Trisquel 8's software updater.
I misspoke earlier when I mentioned mate-terminal.
This bug will be resolved eventually by Trisquel following the upstream sources in
Ubuntu, so barring objections I will close this issue.

Please close by sending an email to 38940-done@debbugs.gnu.org with
some explanations when you judge it is resolved; even if it is *not* a
bug of Guix but a _bug of Trisquel_. ;-)
All the best,

Héhé! It is what the comment you wrote in `supports-hyperlinks?' says. :-)
1. Instead of INSIDE_EMACS, the variable name NO_SUPPORT_HYPERLINK or
other seems more meaningful. Maybe?
2. The comment should go in the docstring.
What do you think?
All the best,

Actually the goal was to remove ‘INSIDE_EMACS’ from there once a
widespread-enough Emacs version supports it, which could be within a
year. And since other terminals are supposed to ignore it altogether, I
would rather not add a special environment variable.
WDYT?

I tend to write “implementation details” as comments, while keeping pure
descriptions of the interface as docstrings; I think it’s OK. :-)

Which Emacs version support it? I'm using Emacs 26.3 from master, and see
the escape sequences in eshell. They seem to be correctly ignored in M-x
shell.

Emacs 26.3 does not support it; all I know is that there’s a patch by
José Marchesi floating around.
