Re: export from an imported module

[Damien Mattei <damien.mattei@gmail.com>]

thank you
it works now for the first time, i do not really know what was wrong, i just do:
rm -rf .cache/guile
and tried a re-export and it is ok.
I know the local cache but between multiple architecture with same
code shared via dropbox can cause problems

now it is ok like in Racket code, i again have a module version of
Scheme+ (no more need to includes files all is in a module now):


(define-module (Scheme+)

  #:use-module (for_next_step)
  #:use-module (growable-vector)
  ;;#:use-module (ice-9 local-eval)
  #:use-module (infix-operators)
  #:use-module (overload)
#:use-module (array)
  #:use-module (ice-9 match)
  #:use-module (ice-9 arrays) ;; for array-copy
  #:use-module (srfi srfi-1) ;; any,every
  #:use-module (srfi srfi-69) ;; Basic hash tables
  #:use-module (srfi srfi-31) ;; rec
  #:use-module (srfi srfi-26) ;; cut


#:re-export (for
           for-basic
           for-next
           for-basic/break
           for-basic/break-cont
           for/break-cont

           define-overload-procedure
           overload-procedure

           define-overload-existing-procedure
           overload-existing-procedure

           define-overload-operator
           overload-operator

           define-overload-existing-operator
           overload-existing-operator

           define-overload-n-arity-operator
           overload-n-arity-operator

           define-overload-existing-n-arity-operator
           overload-existing-n-arity-operator

           overload-function ;; see how to do the same for operator,
see the possible problem with infix precedence?


           ;;$ovrld-square-brackets-lst$

           overload-square-brackets
           ;;find-getter-and-setter-for-overloaded-square-brackets
           find-getter-for-overloaded-square-brackets
           find-setter-for-overloaded-square-brackets

           infix-operators-lst
           set-infix-operators-lst!
           replace-operator!
           )

  #:replace (do when unless)

  #:export ($nfx$
        !*prec

        def $bracket-apply$ <- ← -> → <+ ⥆ +> ⥅ declare $> $+> condx ≠
** <v v> ⇜ ⇝ repeat % << >> & $ | ) ;; <> is already defined in Guile

) ;; end module definitions

simply used like that:

(use-modules (Scheme+)
         (matrix+)
        ; (infix-operators)
        ; (overload)

         (srfi srfi-42) ; Eager Comprehensions
         (oop goops)
         (srfi srfi-43)) ; vectors

no more need to add the sub-modules of Scheme+ : infix-operators ,
overload, for_next_step in the main program ,just (use-modules
(Scheme+)) is enought.
