Failing to use guile-bash

Failing to use guile-bash

[David Larsson]

Hi,
I installed the guile-bash package and tried to use it as below but 
can't get it to work. Anyone who is successfully using it?

So far, I have done:
guix package -i guile-bash
enable -f ~/.guix-profile/lib/bash/libguile-bash.so scm

then created the file example.scm with the following content.
(use-modules (gnu bash))
(define-bash-function (dtach-start-emacs)
    (unless (file-exists? "/tmp/emacs.dtach")
      #$ [dtach -n /tmp/emacs.dtach emacs]))

and then ran: scm example.scm

which gave the following error message:
;;; compiling /home/user1/src/code_guile/example.scm
;;; WARNING: compilation of /home/user1/src/code_guile/example.scm failed:
;;; ERROR: In procedure scm_lreadr: example.scm:18:8: Unknown # object: 
#\$
ERROR: In procedure scm_lreadr: 
/home/user1/src/code_guile/example.scm:18:8: Unknown # object: #\

Not sure what's missing. All suggestions appreciated.

It seems the reader gets confused by

I don't now how guile-bash is supposed to be used
I didn't know guile-bash existed and I can't find it anywhere on line

All that said, you could try asing on the guile users mailing list

Maybe there's someone, there, who's not following guix related things

unfortunately the project is currently retired:
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/guile.scm#n1751
«
   ;; This project is currently retired.  It was initially announced here:
   ;; <https://lists.gnu.org/archive/html/guile-user/2015-02/msg00003.html>.
»

and the git repo appears to be deleted

 https://anonscm.debian.org/cgit/users/kaction-guest/retired/dev.guile-bash.git

unfortunately the other project guile-scsh (Guile Scheme Shell) is
bitrotten according to this
https://www.gnu.org/software/guile/manual/html_node/The-Scheme-shell-_0028scsh_0029.html

so the two projects I'm aware of are unmaintained :-( (I'm still not able to
even think contributing)

going a *little bit* OT...

(**disclaimer**: I'm an Emacs newbie _addicted_ so I'm much biased

a possible alternative I can suggest you is to explore Eshell [1], the
Emacs eshell: it's not a POSIX shell replacement but it's an interesting
interface to our operating system, and we can script it [2]

on this matter I found an interesting (long) article worth reading
https://web.archive.org/web/20181014151102/https://ambrevar.xyz/emacs-eshell/

«Back in the days, VT-like terminals were our main mean of communicating
with a machine. Decades went by, our desktop computers can now handle
gigabytes of buffering and display in 24-bit colors, and yet we still
stick to terminal emulators, that is, programs that emulate the
restrictions of those ancient machines. »

DANGER: that article made me more Emacs addicted

HTH!

The good news is that the code has been archived by Software Heritage:

In other news, you may be interested in Gash:

  https://gitlab.com/janneke/gash/

It’s a different project (a POSIX shell written in Guile rather than a
Scheme shell) but it’s probably relevant.  :-)

Thanks,
