Currently the Accept-Language header is not observed, and instead the
language is set explicitly. As you know, inserting (locale "NO" "no") at
the beginning of the 'tractatus' function would do that (but then it
should better be user-controllable as e.g. in the demo "app/gui.l").

Re: Tractatus Pico-Blaesicus, Accept-Language

[Jon Kleiser]

Hi Alex,

A very nice piece of lisp code! The only part I didn’t like very much, was the 
yellow color. As usual, I had to tweek the CSS. Here is my variant:

# CSS
(de tractatus.css ()
   (prinl "html {background-color: #eee;}")
   (prinl "body {margin: auto; max-width: 96ex; border: 1px solid #bbb; font: 
20px serif; background-color: #ffd; padding: 2em 5% 4em 5%;}")
   (prinl "ul {padding-left: 3ex; list-style: none;}")
   (prinl "li {padding: 0.3ex 0;}")
   (prinl "a {text-decoration: none}") )

As I noticed that the clickable lines in the  had tooltips (title), I got 
tempted to check if they were depending on the Accept-Language value 
(no,en-US;q=0.7,en;q=0.3) in my (Firefox) requests, but I didn’t see any 
Norwegian tooltips. Are there other PicoLisp demo apps where the displayed 
texts (or tooltips) are according to the Accept-Language value in the request 
header? I’m just curious. ;-)

Re: Tractatus Pico-Blaesicus

Nice to read, Alex.

Besides the interesting technical implementation,
concerning the content:

I find the variety of all the platforms very interesting,
where picolisp installs nearly out-of-the-box or is already available as 
a package,

especially since the announcement of termux/picolisp on android.
So this is a 'Pro' for me.

Greetings Olaf

And could you please provide us with an English version ?
The automated translators that I tried produced nothing readable
(but I guess the original is somewhat «tarabiscoté»).

Hey, I love this Tractatus!

Very unbiased and fair. (Even acknowledging 2.4!)

hi,

in the beginning of year I've wrote special preface for Forth or coding in
general. In memory of Descartes. It describes zero step before coding.
in Russian:

This should work. However, the browser still believes this is a file,
and it will cache the result instead of calling it each time. So it is
not a dynamic on-the-fly CSS generation.

This is really neat! It's great to see a more "substantial" use of a
read-macro in the wild. And I'm impressed (though not surprised) by
how concise the code is :)

It didn't occur to me that we could use the "!" syntax
as you did to generate css. Would something like this work as well, to
temporarily overide definitions in CSS files?

   (html NIL "My Page" (list *Css "!my-css-tweaks") NIL
  ... )

I don't know if that would actually be useful, just thinking aloud.

Looks pretty good to me. More links could be added, especially for
the DB/Pilog/App Framework. Maybe some links to examples for
'Equivalence of Code and Data' too, and how it makes the language
more expressive in practice?

I also enjoyed the suspense generated by having to click through the
menu.

Thanks for sharing!

Tractatus Pico-Blaesicus

[Alexander Burger]

Dear PicoLisp List,

let me announce a strange little piece of [code?, documentation?,
pamphlet?] which I wrote up to summarize some of the positions and
philosophy of PicoLisp.

In the spirit of Ludwig Wittgenstein I called it

   Tractatus Pico-Blaesicus

and it can be accessed at

   http://picolisp.com/tractatus


On the top-right of the page is a "Source" link.

The code is an interesting exercise in itself:

The HTML entry function 'tractatus' consists mainly of a read-macro
which parses the embedded plaintext block into a '' structure,
with the hierarchy based on the individual indentation levels.

To have it all together in a single source, the CSS "file" is in fact
the function 'tractatus.css', as well as the source download link
'tractatus.l' (despite their names).


I suspect that the text is not complete yet, and probably neither
error-free nor particularly consistent. Let me know what you think
should be added or changed.
