Hello,
i released Scheme+ for Guile version 9.1:
https://github.com/damien-mattei/Scheme-PLUS-for-Guile
It is a big refactoring of code,now completely implemented with modules and
still use syntax transformers.
It add very few new features but it is a complete refactoring of the code
hello,
i released the version 9.0 of Scheme+
https://github.com/damien-mattei/Scheme-PLUS-for-Guile
New in this release:
No more need to parse the file+.scm file ,all parsing is done at
pre-compile time in macro.
This makes the use of Scheme+ transparent for the user.
https://github.com
yes it works.
thanks
i will use this version,it is simpler

Hi,
why does
(string->symbol "#:hello")
$1 = #{#:hello}#
gives #{#:hello}# in guile instead of #:hello ?
like in Kawa or Racket
i understand it is special to guile as i can write:

$1 = #:hello
but then how can i generate a #:hello from a string or a list of char?

hello,
i have problem i do not understand when inserting a file in a module,
things i never done before:
(define-module (matrix)
#:use-module (oop goops)
#:use-module ((guile)
#:select (*)
#:prefix orig:)
#:export (
matrix
matrix-v)
)
(define scheme-plu
y-matrix-matrix M Mc)))
there should be no difference for computation in Guile ,just that i
will use GOOPS instead of struct and that it should be a guile module
written in scheme+ syntax
see it when finished

hello,
does anyone know if it exists a basic matrix library for Guile?
just need to multiply a matrix and a vector.

i agree with you all but there is a misunderstanding of what i'm
currently doing.
I'm not making + that append vectors a part of Scheme+, it is just for
a personal program that i want to overload it. This will never be in
Scheme+. (even if python use + for appending list, and list in python
are ha
2 3 4 5)
scheme@(guile-user)> {#(1 2 3) + #(4 5)}
$5 = #(1 2 3 4 5)

hello,
is it possible to overload an existing operator in Guile?
example overload + to concatenate vectors.
for example in Scheme (+ i admit) i can do :
; first stage overloading
(define-overload-existing-operator +)
; second stage overloading
(overload-existing-operator + vector-append (vector?
version 7.1 for Guile of Scheme+
language is already released and available:
https://github.com/damien-mattei/Scheme-PLUS-for-Guile
the doc and features are the same as for Racket:
https://damien-mattei.github.io/Scheme-PLUS-for-Racket/Scheme+io.html
i think when defining procedure in a file or even toplevel, the order
is of no importance , but seems not to be the case for macro if i
remember correctly the examples of the discussion threads last
week,and of course, as you mention it, for defining variables
dependant of each others, the order is
end. start defaults to 0 and end defaults to the
value of (vector-length vec). If end extends beyond the length of vec,
the slots in the new vector that obviously cannot be filled by
elements from vec are filled with fill, whose default value is
unspecified.

hello,
i'm maintaining and developing some code i wrote which is using
something is a hidden feature or bug in vector-copy?
here is the code but there no need to understand it, the problem is
explained after
;; scheme@(guile-user)> (define gva (growable-vector 1 2 3 4 5))
;; scheme@(guile-user)>
yes :-) i will keep it in mind. It is a bit like a let* i tends to
forget it sometimes.

i know what disturb me in this error, it is because the order of
definitions has effect but i always learn (was it right?) that in
scheme the order of definitions should have no effect on the resulting
evaluations.

thank you
it is clear now , even if i really never find the macro needed upward
i tested too in racket your example and the messages is simple to understand :

overload.scm must be before some definitions of scheme-infix.scm even
if it is not used here, it is strange, i do not understand all but it
compiles now

hi,
i have a main Scheme+ module that exports an overload macro:
(define-module (Scheme+)
#:use-module (growable-vector)
#:use-module (ice-9 local-eval)
#:use-module (ice-9 match)
#:use-module (srfi srfi-1) ;; any,every
#:use-module (srfi srfi-69) ;; Basic hash tables

yes i read the section of NEWS:

it seems the cleaning of old .o files solved the problem

which the value of a one dimension vector
i will test again on the MacOS laptop , i remembered i had cleaned the
cache too ,so it is very strange... if it still fail i will activate
your debug info i never used but problem does not seems to come only
from my code.
On Tue,
yes Zelphir, sorry ,why i forgot the subject? i do not know
, i'm using gmail and the feature for editing the subject is hidden :-(
now it is fixed

i'm perplex , i'm sure now it is related to 'match' because of that:

scheme@(guile-user)> (match '(1 0) ((2 0) 'nomatch))
