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.


welcome message.

So ideally when we read from standard input we should not include the

This is sensible:

 $ echo echo Hi. | bash
 Hi.

This is not:

 $ echo '(display "Hi.\n")' | guile
 GNU Guile 3.0.2

 under certain conditions; type `,show c' for details.

 Enter `,help' for help.
 Hi.

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. $ Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'. This program is free software, and you are welcome to redistribute it 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]
 $





Kind regards,

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?
