Hi,
With the default settings, guile's compiler warns about a format string
that is returned by the gettext function.
How to reproduce:
================================= prog.scm =================================
(use-modules (ice-9 format))
(setlocale LC_ALL "")
(textdomain "prog")
(bindtextdomain "prog" ".")
(define n (string->number (list-ref (command-line) 1)))
(format #t "~A~%" (gettext "'Your command, please?', asked the waiter."))
(format #t "address@hidden" (ngettext "a piece of cake" "~D pieces of cake" n)
n)
(format #t "~A~%" (format #f (gettext "~A is replaced by ~A.") "FF" "EUR"))
============================================================================
$ uname -srm
SunOS 5.11 i86pc
$ guile --version
guile (GNU Guile) 2.0.3.152-c5f6c2
...
$ guile -s prog.scm 2
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;; or pass the --no-auto-compile argument to disable.
;;; compiling /home/bruno/gettext-0.18.2-32-static/gettext-tools/tests/prog.scm
;;; /home/bruno/gettext-0.18.2-32-static/gettext-tools/tests/prog.scm:13:18:
warning: non-literal format string
;;; compiled
/home/bruno/.cache/guile/ccache/2.0-LE-4-2.0/home/bruno/gettext-0.18.2-32-static/gettext-tools/tests/prog.scm.go
'Your command, please?', asked the waiter.
2 pieces of cake
FF is replaced by EUR.
Given that
- It is normal for a program to be internationalized,
- It is normal for an internationalized program to have its format strings
passed through the gettext function.
such situations should not produce warnings with the default settings.
It's OK in my opinion to have this warning enabled through special options
or settings, though.

The ‘format’ warning is in ‘%auto-compilation-options’, but it can be
turned off at the user’s option.
Thanks,
