[Message part 3 (text/plain, inline)]

Consider files

foo-runner.scm:
(import (foo)
        (scheme write))
(display (bar))

foo.scm:
(define-library (foo)
    (import
      (scheme base)
      (ice-9 regex))
    (export bar)

    (begin
      (define (bar)
        (make-regexp "a"))))

Running this with guile -L . foo-runner.scm, yields error
foo.scm:1:0: In procedure bar:
Unbound variable: make-regexp

It seems using other libraries is fine; eg it works if I change foo.scm to
(define-library (foo)
    (import
      (scheme base)
      (ice-9 match))
    (export bar)

    (begin
      (define (bar)
        (match "a" (_ "bar")))))

It also works if I try using regexp from application instead of module; eg
if I change foo-runner.scm to
(import (foo)
        (scheme write)
        (ice-9 regex))
(display (make-regexp "a"))

I'm running version 3.0.5, installed through debian testing branch package
manager

Hi,

The issue AFAIU is that make-regexp is part of (guile), and not exported
by (ice-9 regex).  You would need to add (only (guile) make-regexp) to
your import set.  I know it's somewhat terrible but perhaps in the near
future we will be able to replace this regexp support with something
more consistent.

Please reopen if I misunderstood the bug.

Cheers,

Andy
