Hi!
I'm interested in this implementation. Please subscribe me.

Hi all,
Does pico have PDF functions? I was considering implenting something in
that area.
John
Also, I am still having problems getting the PDF function working
properly (i.e., finding useable fonts other than Courier).
Only simple circular lists seem to work properly.
'(a b . (c d e .))
is equivalent to
'(a b c d e c d e ...)
: (de X . (a b .))
-> X
: X
-> (a b .)
: (de X . (a . (b c .)))
# X redefined
-> X
: (cdr X)
-> (b c .)
: X
-> (a b c b c b c b c b c b c b c b c b c b c b c b c b c b c b c b c
b c b
The + shows up in post data too, when the default "application/x-www-
form-urlencoded" content type is used and there are spaces in a value.

The T argument to (date) returns UTC, and the T argument to (time)
returns the time at the call to date. If (date) was called with the T
argument, the time will be in UTC.
The T argument to (tim$) returns a string with second

Thanks, Henrik!
I wish I'd known about your website earlier. Perhaps Alex can link to
it so it's more googleable?

If the socket is set not to block, then the socket will read as much
data as is available and the underlying read call will return the
number of bytes read, right? So the poll will still be useful in an
nbio world.

I thought Chicken's approach seemed novel, but I don't understand it
well enough to explain it. From what I gather, they use the C stack as
the "new" heap and collapse it when the garbage collector copies.

I think what may be happening is gcc is trying to build a universal =20
executable and can't find any ia64 stuff.
Try this change in Makefile:
from:
ifeq ($(shell uname), Darwin)
OS =3D Darwin
PICOLISP-FLAGS =3D -lc -lm -ldl
to:
ifeq ($(shell uname), Darwin)
OS =3D Dar
Is it necessary to declare the functions extern in the header file?
The default linkage for functions is external.

Alex,
Have you tried discussing the issue nicely on the talk (Diskussion)
page? There hasn't been any talk in German, which is very strange for
an article that has been marked for deletion.
One problem that I see is that, generally, wikipedians should not be
writing about their own stuff.

This is because A still points at the cons that was the head of the list
before sorting. If you want to update it, you have to set A to the result
of sort.

I think using (list 'a (list (list V))) is idiomatic and clear.

Wildcard expansion in UNIX is performed by the shell, so to experiment with
arguments it is probably better to specify a directory as an argument and
see the result. You can use a native call to the glob(3) lunch function if
you want pattern matching lookup like the shell, or use the output of
find

Yes, it makes more sense in reducing type languages like scheme and
Haskell, where its operating model is identical to the recursion that would
normally be implemented.

Thanks, and I probably should have said, "car and cdr of a cell" rather
than a list. Oh well ;)
