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

I am not a lawyer, but it seems to me that libguile could be under LGPL,
but guile the executable could be under GPL, and therefore use readline by
default.

As you say, there would have to be an option to turn it off. Maybe
--no-readline?

Sometimes readline gets in the way, for example, when using guile with emac=
s.

If it was enabled by default, then there also must be an option to disable =
it when not needed.

The main reason readline is not enabled by default (IIRC), is the license d=
ifferences between readline and guile. (GPL and LGPL)

Hi,

Not having readline at the guile interpreter from the get-go in a GNU
environment was a quite scarring experience for me, so it would be great
to have a way to enable readline by default.

init.scm could provide that, but:

<wingo> it seems to search the load path for init.scm
<wingo> before loading anything else
<wingo> tricky though, apparently that happens even before loading boot-9=


Ideally there should be either a compileflag or a systemwide config file
to enable readline support in the whole system. If it is a compile-flag
it might be useful to not make it default, because developers why
develop proprietary applications could then by accident compile a
program with activated readline support.

If such a flag existed, most GNU/Linux distributions could simply
activate it for guile itself (as long as they do not ship unfree scripts
using guile which depend on readline support =E2=80=94 those scripts woul=
d
violate the GPL, but they would not work at all without readline
support, so this dependency should be pretty clear).

Best wishes,
Arne
