Hi Christophe.
AFAIK ClojureScript is pretty much feature complete as opposed to Emu,
there's a risk for confusion and perhaps bad PR if an online REPL
based on Emu becomes the de facto way of playing around with PL for
novices, ie "Why can't I do X which the manual seems to imply?!!" or

Hello,
It is a local shell that connects to a local webserver.
It can be used for webdevelopment, you can expect variables and so on.
(app) open a new process with a new port. So each process and each single
user linked to it can has a own state. The user can connects to his new
port.
Does it
Hi Alex,
Only when an object is accessed (value, property list etc.), it is
automatically loaded into the Lisp heap as an external symbol.
And once loaded, they can be garbage collected when needed, right?
The current database files are in a binary format (called PLIO for
PicoLisp I/O).
Hi Henrik,
When you have a database of several hundred GB, have you used the
ability to split it up? If so why and how, what considerations went
into the splitting decision?
Yes, split up in several types of application that communicate with each
other, where each application has its own DB
Hi Kriangkrai,
Ah, Thanks. Could you please explain how a double value is encoded
in cell? I could not decipher doubleToNum() and numToDouble() in
big.c!
As PicoLisp only handles scaled fixed point numbers, the double is
encoded as a number, with the additional scale passed to the functions.
Hi Kriangkrai,
A tutorial on PicoLisp FFI would be great; with that, PicoLisp would
have no shortage of libraries! ;-)
not exactly a tutorial, but I have looked into this a while ago and
you can find a prototype ffi generator at
http://logand.com/mplisp/src/mod/ It should be fairly
Hi Kriangkrai,
Because with (@ attr1 val1 ...), you can retrive the attributes by
just using (assoc '@ sxml).
Is there any advantage of using your syntax @attr1 val1 ...?
advantage is that you don't have to put the attributes in a list
manually, your 'with-xml' function can do that for you;-)
Hi Kriangkrai,
Is there a way, to make the code below works, the first time 'foo' is defined?
: foo
- NIL
: (mydefs (+ 1 (foo 3 4))) # should returns 20
As I said, not without modification of the low-level error handler.

Hi Alex,
As I said, not without modification of the low-level error handler.
Execution is not continued after the error is caught, as the 'catch' is
in 'mydefs' and not on the lowest level.
Why would you need that?
It will enable code like this:
(with-xml
(tag1 (@ attr1 val1)
Hi Kriangkrai,
Also, floating point calculations are better done separately (there are C
functions for that)
Do you mean using FFI, i.e. calling C functions from Lisp? If so, how?
Could you give me an example for calling C's double sin(double x) in
math.h.
Please take a look in
Hi Kriangkrai,
(with-xml
(tag1 (@ attr1 val1)
text
(tag2 text)
text ))
If you go this route, why not something like:
(with-xml
(tag1 @attr1 val1
text
(tag2 text)
text ) )
Also, if you don't manage to hook your error handler to
Hi Tomas,
=A0 =A0(with-xml
=A0 =A0 =A0 (tag1 (@ attr1 val1)
=A0 =A0 =A0 =A0 =A0text
=A0 =A0 =A0 =A0 =A0(tag2 text)
=A0 =A0 =A0 =A0 =A0text ))
If you go this route, why not something like:
(with-xml
=A0 (tag1 @attr1 val1
=A0 =A0 =A0text
=A0 =A0 =A0(tag2 text)
=A0 =A0 =A0text ) )
Hi Alex,
Please take a look in src/ext.c. There is, for example, 'ext:Sin',
that interfaces to scaled integers:
=A0 : (ext:Sin 314159 10)
=A0 - 0
=A0 : (ext:Cos 314159 10)
=A0 - -10
