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").
I'd be interested i

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.

With Guile's default reader options, R6RS hex escape and EOL escape

`r6rs-hex-escapes' option, and gets us closer to the latter by setting

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

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).

With Guile's default reader options, R6RS hex escape and EOL escape
behavior is missing. This change enables the former via the
`r6rs-hex-escapes' option, and gets us closer to the latter by
havior by default, but provide a command-line switch; however,
enabling this behavior is *already* possible using command-line switches

you still have to watch the order of your port
type checks, testing for `binary-port?' first, whereas on systems
following R6RS strictly, you'd get the same behavior regardless of type
check order. I can live with the latter, but the former would be

from sbank's tutorial:
To stress that: if a C library provides gobject-introspection
metadata, you should be able to use it via sbank without further ado.
However, while the metadata provided in the .typelib file is complete
enough to yield good and "schemely" bindings, there might still be
some corners in the API that profit from some glossing over, and sbank
provides such glossing where and when such cases are identified.

After getting no feedback on my last mail so far, here is a series of
proposed patches for the stable-2.0 branch. In total, they speed up the
unzip benchmark by a factor of about 4.7, but it's still about 1.8 times
slower than what we'd get for using generic (non-fixnum) operations.

So what remains as (quite) hard dependencies would be: foof-loop, fmt,

This is another piece of my attempt at getting more speed out of the
`(rnrs arithmetic fixnums)' library. The idea is that this patch would
be applied to master. I think, at least in the current form, it is not
eligible for 2.0.x, as it messes up the VM opcode numbers, which breaks
all .go files,
This primitive can be used to significantly speed up the operations in
`(rnrs arithmetic fixnums)'.
* libguile/numbers.c (scm_fixnum_p): New predicate.
* libguile/numbers.h: Add prototype.
* libguile/vm-i-scheme.c (fixnump): New VM primitive; renumbered
subsequent operations.
* module/language/
* module/rnrs/arithmetic/fixnums.scm (assert-fixnum): Is now a
macro.
(assert-fixnums): New procedure checking a the elements of a list
for fixnum-ness. All callers applying `assert-fixnum' to a list
now changed to use this procedure.
* module/rnrs/arithmetic/fixnums.scm (define-fxop*): N
In porting dorodango[0], I have noticed that Guile's R6RS fixnum
operations are quite slow; here's a patch to remedy that a bit. The
patch contains a benchmark for `fxxor', which experiences a performance
improvement of >2 with the patch.

something entirely Guile-specific, but I want to point out that there's
already a good amount of code out there, and even some documentation
;-). I'd be thrilled however, if some ambitious, careful hacker would
join me and help me enhance dorodango to work perfectly as Guile's
package manager!

As always, see the patch header for details.

n't matter, as git seems
to handle duplicate changes quite well (just tried, except for a
conflict in GUILE-VERSION, stable-2.0 merged cleanly into master, even
with the duplicate changeset). Thoughts?
