Hi,
The 'call' function seems to disable echo. Also, The Enter key does
not end an input line, Ctrl-J must be used instead.
When I run: (call 'sh "-c" "echo -n 'name: '; read name; echo $name")
It outputs "name :" and waits for input. I type something (e.g. "abc")
but nothing echo. I press the En
Hi Alex,
I have a patch to add block comment (#{}#) and unescape string
({$.$}) syntax.
Do you think that the syntax will affect old code? Should it be added
to the standard distribution?
Best regards,

Hi Alex,
With unescaped string, we don't need to worry escaping (e.g. "\""
"\^"), well except ensuring that there is no "$}" in the string. With
that, we can generate files easily, e.g.
(out "t.html" (prin {$.$}))

Hi Alex,
Yes, it's ok to include only block comment :-)

Hi Alex and Tomas,
In PLT Scheme, you can comment out a single expression with "#'" (e.g.
.. #'(+ 1 2) ...). It would be great to have such kind of comment
too, but I don't know how to do it easily. :-(
In fact, my #{...}# syntax is inspired by the #|...|# syntax in PLT
Scheme (but in PLT, it can
Just to correct my mistake. It is "#;", not "#'", for
single-expression comment in PLT Scheme.

Hi Tomas,
Thanks for the code. But my intension for unescaped string is for
"casual" template (most of text are static strings) and embedding
files (without creating separate files).
It would be great if PicoLisp have "quasi-quotation", so the code
could be something like:
(out "t.html"

Hi Alex,
I've found a way to make it works, but only when I load the file in
the PicoLisp prompt, not when the file is loaded from command-line
argument.

Hi PicoLisp's Vimers,
As I could not find a PicoLisp syntax for Vim, so I created one myself
(well, by looking at Lisp/Scheme syntax files).
Just copy the contents of the attached file into your ~/.vimrc. And
modify it if you don't like the result! ;-)

Many thanks! Now it works, though it would be much better to have

One problem with 'fill' is that the expressions to fill cannot be
anonymous (it must be the result of a variable), e.g. to f

Hi Henrik,
My purpose of block comment is not to comment out multiple lines, for
that I would use single line comments too.
I would use block comment to comment out small part in a line, e.g.
(list 1 2 #{3 4}# 5)
or to comment within context, e.g.
(de f (A #{...}# B #{...}#)
Hi Henrik,
You may call me KS.
It's NOT my intention to fork Pico Lisp! I just need some features. If
I can do them myself, I implement and share them back. If I do not
know how, I request them or ask for an alternative solution. It's OK
for my contribution to not be included in standard Pico Lis

Sure. Kriangkrai is my first name. KS is from K for Kriangkrai (my

Hi Alex,
More questions ;-)
1. In FFI, it seems that 'boxCnt()' (not 'box()') must be used to
return a correct value, why? When 'box()' should be used instead to
return a value? (I see many places in C source that use box() when
returning a value.) Which one should be used to return a
pointer/add

Hi All,
This is my attemp on FFI (Foreign Function Interface). It is based on
Tomas's work and Alex's answers. Thanks you both! It should work on
standard PicoLisp. I hope that it would be useful as a starting point
for people new to PicoLisp wanting to interface with C libraries.
