readline (again...)

readline (again...)

[Orm Finnendahl]

Hi all,

sorry to bug you again, but I experience a strange thing trying to use
readline within an inferior guile process in emacs: When loading the
readline modules in a console, the behaviour of readline is the way
it's expected, activating it from within an inferior-scheme buffer in
emacs makes guile loose its prompt (<guile>) and no history or any of
readlines features seems to be available.

What am I missing?

It doesn't really make sense to activate readline when running within
Emacs, as Emacs provides its own mechanisms for editing, recalling
previous commands, and so on.  To activate readline only when it makes
sense, I recommend using the following code in your .guile:

(if (isatty? (current-input-port))
    (begin
      (use-modules (ice-9 readline))
      (activate-readline)))

Regards,
        Neil
