bug#15253: readline completion for modules

[Arne Babenhauserheide (IMK)]

Hi,

It would be very convenient to have readline completion for modules, so
I could just type

,use 

or

,use srfi 

or

(use-modules (

or

(use-modules (srfi 

and get a listing of possible modules.

That would allow staying in the same context while checking for modules
(instead of switching to info or the web).

This could be taken even further by also providing readline support when
using @ (with the pointer in or at the place of every variable marked
with ˇ while hitting tab):

(@ (ˇsrfi ˇsrfi-13) ˇstring-unfold)

This could go to the completeness of the emacs auto-complete, which
allows completing stuff like ˇ-expand and -expand-ˇ. I could
then say “I know that I need the function string-unfold, where can I
find it?” To answer that question I’d use

(@ ( ) string-unfold

and get a list of potential modules to use (or rather options for (@
(category module) string-unfold)).

Best wishes,
Arne

bug#15221: provide a mechanism to activate readline systemwide

[Arne Babenhauserheide (IMK)]

I am not a lawyer either, but I know that the license of the executable
does not place restrictions on the license of the guile-specific code
(as long as that code is GPL-compatible).

Best wishes,
Arne
