I'm trying to document my work with Guix using Emacs Org. If I run a shell/sh/bash source block in org-mode, the result has control characters in it.
To reproduce, open a clean instance of Emacs with emacs -q, switch to the scratch buffer and insert:
;; eval this first so that source blocks can run sh
(org-babel-do-load-languages
'org-babel-load-languages
'((shell . t)))
#+begin_src sh :results output :session test
guix package -u
#+end_src
#+RESULTS:
: guix package: ^[[1;35mwarning: ^[[0mnothing to do
Switch to org-mode, eval the lisp, and C-c C-c the source block. If your system is like mine, you'll see control non-printable characters.
When I check how org sees the shell, I get:
#+begin_src sh :results output :session test
echo $TERM
#+end_src
#+RESULTS:
: dumb
I've tried renaming .bashrc and .bash_profile to .bashrc.old and .bash_profile.old, starting a new shell and running through the steps above. The result is the same.
Thoughts and suggestions?

You should try the environment variable INSIDE_EMACS with turns off
some fancy shell things.

This is a good suggestion. Maybe I'm misunderstanding how INSIDE_EMACS works. The docs say:
"Emacs sets the environment variable INSIDE_EMACS in thesubshell to ‘version,comint’, where version is theEmacs version (e.g., ‘24.1’). Programs can check this variableto determine whether they are running inside an Emacs subshell."
https://www.gnu.org/software/emacs/manual/html_node/emacs/Interactive-Shell.html
When I check it in a session set up as described above, I get the Emacs version:
#+begin_src sh :results output :session unset
echo $INSIDE_EMACS
#+end_src
#+RESULTS:
:
: 27.2,comint
I understand this to mean that INSIDE_EMACS *is* being set and that it's the guix command's responsibility to do something with it (if it wants to).
If instead I set INSIDE_EMACS to something falsey (e.g. 1) and run through things, I see the same result with color and control characters.

Thanks for the pointing the Emacs doc. From my understanding, the
environment variable INSIDE_EMACS is used by Guix to turn on/off
hyperlink support. It reads,
--8<---------------cut here---------------start------------->8---
(define* (supports-hyperlinks? #:optional (port (current-output-port)))
"Return true if PORT is a terminal that supports hyperlink escapes."
;; Note that terminals are supposed to ignore OSC escapes they don't
;; understand (this is the case of xterm as of version 349, for instance.)
;; However, Emacs comint as of 26.3 does not ignore it and instead lets it
;; through, hence the 'INSIDE_EMACS' special case below.
(and (isatty?* port)
(not (getenv "INSIDE_EMACS"))))

Indeed, Emacs sets automatically this variable. That’s why it is used
by Guix. :-)

Yes.

Thanks for reporting. I though tweaking that variable would be enough to
fix the odd behaviour you are seeing,
--8<---------------cut here---------------start------------->8---
: guix package: [1;35mwarning: [0mnothing to do
--8<---------------cut here---------------end--------------->8---
which are related to shell fancy “controllers”. If you have not tried
yet, then NO_COLOR=1 should do the job. Sorry to not have thought
before. :-)
Cheers,
simon

I was thinking there would be a catch-all, but it looks like I need to ensure that various environment variables are set. It looks like we need to identify a few more.

It looks like NO_COLOR removes colors as expected (which is great). However, there are other characters which appear that are undesirable. They are characters which copy correctly in email, but don't work within org or it's html export. They render in Emacs as ^M^[[K and ^H. Here's a kill-yank of a session (removed some progress bars, but I'm sure you get the point):

My goal has been to clean up the guix command output as seen in an org-babel results block. I'm blogging about Guix using org-babel and Org's export functionality. I want the shell output as seen in the final html to be a reasonable approximation of the shell output a user would see if the command were run in something like xterm. Based on feedback from people in the Org community, I thought there might be a way to toggle off certain characters.

I agree that handling this in org makes sense. When I asked the Org people, they had said it was a Guix issue. And with what we found with NO_COLOR, fair enough. You also raise a good point, however, that the characters originate upstream. Anything Guix might do would be a work around and work arounds are probably best handled in Emacs.

Thank you for the example. I was unaware of the Emacs function ansi-color-apply-on-region. The rest can probably be handled with replace-match.
I appreciate all your help. Thank you, Simon!

I understand. Somehow, the output of Guix CLI is dynamic where Org
babel captures static text (the last output). Therefore, maybe you
could demo using Gifs or something in this flavor.

Some special characters (as coloring) are from Guix and it should be
possible to turn them off. However, others are from progress-bars;
some from Guix itselfs, other from guile-git. Therefore, I am not
sure what you are asking, I mean, are you asking to be able to turn
off all the progress-bars?

Yes, my example was just... an example. I am sure one could come with
more complex filters for formatting adequately.
Cheers,

Okay, I see the confusion. No, I'm not looking to remove the progress bars, but instead have them display as much like the guix command output would look after execution completes in a standard terminal. At this point that probably means replace ^H with something like space, ^M with something like \n, etc.

That's my goal after having talked with you. :) Thank you for your time and help.
