From my experience, trying to come to grips with pioLisp, I would argue
in favour of showing the simple example to explain the concept AND then
showing the complex, safe example and explaining why it is more robust
and suitable for production use. I agree that there's way too many
cases, for o
I've been thinking about the issue of needing Transient symbols.
On the whole I think it will be better to use transient symbols where necesary.
My line of though is that using destructive operators is exactly where
this is an issue. And that is what I'm trying to write about. I have
to say I'm al
Thanks Alex,
I had misgivings about using eval in my code, and a feeling that there
must be a better way.
The inability to add NIL is something I completely missed, though.
True not somthing that you would ordinarily do at the prompt but quite
likely deep inside application code.

Good idea! This will give a lot of useful and practical examples.

Hi All,
OK here's an example of using con and set. which I'm planning to put
up on the wiki.

Hi Thomas,
Well the current mode of operation is to generate html pages on demand.
What about pre-generation. If I recall correctly that is something
which the Apache Cocoon framework supports. basically tell the system
. walk through all your pages generate the HTML and save to a file.

Hmm.
var - Variable: Either a symbol or a cell
(set 'var 'any ..) -> any
Stores new values any in the var arguments. See also setq, val and def.
Even taken in concert these two snippets don't actually explain what
will happen if var is a cell. It may be obvious (if you already know)
that if

Hi Alex,
Well thats two improvements to the documentation. The description of set says:
Stores new values any in the var arguments. I suspect it should say
what you said above. and have a see also link to con.

The 'set' function puts a value into the CAR part of a cell (no matter
whether this is a list cell or a symbol).

There has been some prior discussion on the list:

It might or might not be of help.

Hi,
is there a way of cutting a circular list. for that matter how do we
manupulat cons structure. This is one of the places where things in
Pico do not work like I expect.
(set 'A (1 2 3 4))
(set 'B (cdr A))
Now in Common Lisp I can do:
(setf (cdr A) nil)
and I will get:
A = (1)
18 matches
