[Gcl-devel] write-char and format ~c strangeness

[Camm Maguire]

Greetings!  I think this has been fixed in cvs head.  Please let me
know if this is critical to you for 2.6.8.

(format t "a~cb~%" #\space)
a b
NIL

>(write-char #\space)
 
#\Space

>(write-char #\Space)
 
#\Space

>

This follows clisp from what I can tell.

Hello,


GCL 2.6.7 on Linux shows the following output:


(format t "~c~%" #\space)
 => Space
(write-char #\space)
 => #\Space


According to CLHS, the correct output hinges on whether #\space
is a "simple character" or not. I spent a few minutes trying to figure
it out, but couldn't get anywhere. Oh well.


SBCL and Clisp both output an empty space for these.
Also, iirc the CLHS has examples which show empty spaces for these.


Maybe someone can look into this.


Thanks very much,
Robert Dodier
