Subject: bug#52218: Unable to define more than one R7RS library per file
Date: Wed, 1 Dec 2021 07:45:53 +0000 [thread overview]
Message-ID: <20211201074553.bzuoffwpaxw3da44@localhost> (raw)
In-Reply-To: 20211201074553.bzuoffwpaxw3da44.ref@localhost
Guile is unable to handle more than one define-library per file. For
example, this is "mylibs.sld", which contains two define-library:
(define-library (example mylib)
(import (scheme base))
(export f)
(begin
(define (f x)
(+ x 1))))
(define-library (example main)
(import (scheme base)
(scheme write)
(example mylib))
(export main)
(begin
(define (main)
(display "The answer is: ")
(display (f 1))
(newline))))
When loading this file into Guile using "guile -l mylibs.sld", or by
using (load "mylibs.sld"), Guile will show this error:
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;; or pass the --no-auto-compile argument to disable.
;;; compiling /home/user/mylibs.sld
;;; WARNING: compilation of /home/user/mylibs.sld failed:
;;; Syntax error:
;;; unknown location: definition in expression context, where definitions are not allowed, in form (define (main) (display "The answer is: ") (display (f 1)) (newline))
ice-9/psyntax.scm:2794:12: In procedure syntax-violation:
Syntax error:
/home/user/mylibs.sld:14:4: definition in expression context, where definitions are not allowed, in form (define (main) (display "The answer is: ") (display (f 1)) (newline))
The error is always caused by the second define-library. Apparently,
Guile no longer understands that define-library is a special form by the
time the second define-library is evaluated. Is it not possible to
define two R7RS libraries in the same file?
Guile version: 3.0.7
