Pierre,

and... it works! O.o
Don't you hate it when that happens? Ban bug suicide.
(Does that mean this one can be closed? Or retitled, if we want
to debug Nyxt? :-)
For future reference, it's also works in Common Lisp:
(uiop:run-program '("guix" "repl") :input s :output t
:error-output nil))
Well, I stranded trying to import (or whatever the CL term is)
UIOP itself, but my Common Lisp-fu is hella weak.
However this brings me to another issue: the program output is
prefixed
with the REPL welcome message which is printed to stdout.
So ideally when we read from standard input we should not
include the
welcome message.
That's a question for Guile channels, but I totally agree. It's
annoying and nowhere near ‘an interactive mode’ as suggested by
the GPL3.
This is sensible:
$ echo echo Hi. | bash
Hi.
$
This is not:
$ echo '(display "Hi.\n")' | guile

Hi.
scheme@(guile-user)>

Any clue how to do that?
The following line in my ~/.guile does just that:
(set! repl-welcome (const #t))
...unfortunately, it doesn't work late:
$ echo '(use-modules ((system repl common))) \
(set! repl-welcome (const #t))' | guix repl
[shouty noises]
$
It does not appear documented if and how you'd make Guile load a
different (Nyxt-specific) init file name.
This reminds me: do you want Nyxt to call ‘guix repl -q’ to skip
loading ~/.guile to make your UI more predictable & debuggable?
Or keep it as an escape hatch for cool hacks?
Kind regards,
T G-R
