In Xanalys LispWorks, the function write-line does not return its
argument string as its value, but simply returns nil. CLtS mandates
othrwise, so is this a bug?

Thanks in advance,

What version of lispworks are you using? On 4.1,


CL-USER 1 > (write-line "foo")
foo
"foo"

Looks good to me.

Returns nil for me too, I am using 4.1 personal edition for windows.
Looks like a bug.

4.1.19 on Linux also has the bug.

4.1.19 on linux (enterprise) is what I'm using. Trying again...


CL-USER 1 > (setq foo (write-line "foo"))
foo
"foo"

CL-USER 2 > foo

"foo"

It is likely that this was patched by lispworks since the 4.1.00 
release, but I don't see any reason why two 4.1.19's should differ... 
Even if one turns out to be enterprise and the other not. This is not 
where the enterprise-ness should manifest.

I'm assuming you downloaded the patches on the lispworks web site. Did 
you save a 4.1.19 image from that? Are you using the lispworks 
environment? (I saved an image, and am not using the environment, though 
the environment should not make a difference either.)

Otherwise, the only suggestion I have is to submit a bug report.

LW PE users might be out of luck...

I'm using 4.1.19 on linux (professional).

I downloaded the 19 patchset and dumped an image. I'm using the
environment.

The problem is there in this setup:

CL-USER 4 > (lisp-implementation-version)

"4.1.19"

CL-USER 5 > (write-line "foo")
foo
NIL

>

Well, it's fairly trivial to ADVISE around it for those who depend on
the behaviour.

Looks like lispworks has a strange configuration issue between 
professional and enterprise versions. Surprises never cease.

Linux Entreprise Edition:

FRACTAL-WEB 274 > (write-line "foo")
foo
NIL

FRACTAL-WEB 275 > (lisp-implementation-version)
"4.1.19"

Windows Professional edition:

CL-USER 1 > (write-line "foo")

foo
nil

CL-USER 2 > (lisp-implementation-version)

"4.1.19"

I think I have finally figured out what's going on. In the lw GUI 
environment:

CL-USER 1 > (write-line "foo")
foo
NIL

In the regular tty:

CL-USER 2 > (write-line "foo")
foo
"foo"

For whatever reason (which ought to be reported as a bug) the GUI 
environment is eating up the return value from write-line.

Prior to 4.1.20 Lispworks didn't handle this correctly - it returned nil
from write-line. Perhaps he was pointing out that it has been corrected.
