Hi!
As I reported in #39610 [0], `flush-output-port`, aka `force-output` is
no longer working for R6RS transcoded ports. It was still working in
Guile 2.0; the regression was introduced in Guile 2.2, via commit
"8399e7af5 ("Generic port facility provides buffering uniformly").

ot as tedious as it
might sound: the pkg-list.scm file would have to list each SRFI, but the
collection of portable SRFIs can still be maintained in a single source
repository and dorodango bundle (i.e. unit of distribution).

Previously, `get-string-n!' from `(rnrs io ports)' would not throw the
exception required by R6RS, and could not easily do so due to being
implemented entirely in C.
This change fixes this by introducing a corresponding internal C
function reporting errors by return value and reimplementing the
`g
n over a guildhall provided one, when this exists. Right

take precedence to the third-party libraries installed by dorodango.
This would be addressed by making the $GUILE_LOAD_PATH (and
$GUILE_LOAD_COMPILED_PATH) mechanism to not only prepend, but also
append to the compiled-in load path, as implemented by the patch I
posted [0].

This patch series addresses the problem that `get-datum' is using the

Adds an implementation of SRFI 25 on top of Guile's native arrays. The
implementation does not introduce a disjoint type; Guile arrays and
SRFI-25 arrays can be used interchangably, though with different, partly

You could now just implement `acquire-valid-fd' in C and expose it to
Scheme, if that is even necessary. If you have the FD available via
e.g. an environment variable, `acquire-valid-fd' can be implemented in
Scheme as well.

The *symbol* '%nil has absolutely no special status in Scheme. It just
happens that Guile provides (in the default environment) a value bound
as %nil that has special properties.

That's to be expected -- `use-modules' has a different syntax than R6RS'

(import (rnrs base (6)))
or
(use-modules ((rnrs base) #:version (6)))
