The last lines of the newLISP manual function definitions:

======

inc

Use the ++ function for incrementing numbers in integer mode.

----------

dec

Use the inc function to increment numbers.

======

Need to be changed to something like:

======

inc

Use the ++ function for incrementing numbers in integer mode.
Use the dec function to decrement numbers.

----------

dec

Use the -- function for decrementing numbers in integer mode.
Use the inc function to increment numbers.

======

(And if it's not too much trouble ;p)

You added ++ and -- to the +, -, *, /, % table entry
in:

Function Reference

1. Syntax of symbol variables and numbers
2. Data types and names in the reference
3. Functions in groups
* List processing, flow control, and integer arithmetic

Now the table entry is:

+, ++, -, --, *, /, % integer arithetic

Besides looking messy ;p)

When deconstructing the single newLISP manual html file into individual html pages, the ++ and -- sections are not reachable by scrolling down from +, ++, -, --, *, /, %.

Could you change the table to:

+, -, *, /, % integer arithmetic
++ incremet integer number
-- decrement integer number

Lutz,

can you post the link to the odt file when the documentation becomes stable.
I want to compile it to a CHM file as you suggested.

Here I have CHM files belonging to the previous version 10.1.x ,
namely
codepatterns and
introduction-to-newlisp from Wikibooks
Would you prefer me to update them first?

Also I was working on a compiled help file containing the GTK+ Reference Manual for GTK+ 2.18.9 .
The good thing will be to use the reference as contextsensitive help in editors.

Do you and others like them separately or all in one file?

Regards,
Michael

Here is the latest version in OpenOffice ODT format:

http://www.newlisp.org/newlisp_manual-10201.odt

The PDF and HTML versions have been updated too.

Ps: I would keep different formats in different files.

Posted: **Tue Mar 23, 2010 6:19 pm**

Sorry to have missed out on the editing this time round! Thanks to everyone for making theh newLISP manual (even) better!

In some spare moments I've been thinking about ebooks and electronic docs. I've been using the newlisp manual as a real-world example. One thing I tried was this:

Code: Select all

(set 'f (read-file {/usr/share/doc/newlisp/newlisp_manual.html}))
(xml-type-tags nil nil nil)
(set 'xf (xml-parse f 15))

Yes, it doesn't work. But that's just because the manual is in HTML Transitional. I ran the HTML source through BBEdit's version of Tidy - converting it to XHTML. It appears to make little difference to the 'user experience' in a browser - a lot of changes to BR tags and so on, but not much else.

But now that code above works, and produces SXML of the source:

Code: Select all

(html ((xmlns "http://www.w3.org/1999/xhtml")) (head (meta ((http-equiv "content-type") 
     (content "text/html; charset=utf-8"))) 
   (meta ((name "author") (content "Lutz Mueller"))) 
   (meta ((name "keywords") (content "newLISP Lisp SCHEME programming language manual reference Artificial Intelligence AI NUEVATEC"))) 
   (meta ((name "description") (content "newLISP Users Manual and Reference"))) 
...
(a ((name "shell") (id "shell"))) 
   (h2 (span ((class "function")) "!")) 
   (h4 "syntax: (! " (em "str-shell-command") ")") 
   (p "Executes the command in " (em "str-command") " by shelling out to the operating system and executing. This function returns a different value depending on the host operating system.") 
   (pre "\n(! \"vi\")  \n(! \"ls -ltr\")\n") 
...

Yes it looks crazy (but better than HTML), but I can't help thinking that this format might be useful, because you can easily use newLISP on it. For example:

Code: Select all

(set 'xr (ref-all 'h4 xf))
(dolist (r xr)  (println (rest (xf (chop r)))))

gives a list of all syntax definitions, suitable for producing a quick reference guide...

A few questions arise: what are the problems with distributing the manual in XHTML rather than HTML, such that a trip through Tidy wouldn't be necessary? Also, how could you go about outputting the SXML structure to other formats, such as plain old HTML? It kind of looks to me like it could be executable, somehow, if there were definitions for the major tags... And another possibility - could this format be the basis for some kind of newLISP-oriented text editor?

Just a few thoughts... :)

Posted: **Tue Mar 23, 2010 9:41 pm**

peanut gallery here. all of that sounds very cool and useful to me. :-)

Posted: **Wed Mar 24, 2010 12:14 am**

This is a great idea. If you can send me an XHTML translation of the current rev-2 manual from:

http://www.newlisp.org/downloads/newlisp_manual.html

and I can try if it works with my PDF conversion.

Posted: **Wed Mar 24, 2010 1:39 pm**

In the end I succeded to do the XHTML conversion myself, and its online now:

http://www.newlisp.org/downloads/newlisp_manual.html

it can be parsed using:

Code: Select all

(xml-type-tags nil nil nil nil)
(xml-parse (read-file "newlisp_manual.html") 15)

and you can do this:

Code: Select all

> (ref-all '(h1 *) (xml-parse (read-file "./newlisp_manual.html") 15) match true)
((h1 "Contents") (h1 "newLISP Users Manual") (h1 "newLISP Function Reference"))
>

The 'true' flag at the end of 'ref/ref-all' was introduced in 10.1.7 to return the content instead of the index-vector.

Posted: **Wed Mar 24, 2010 6:21 pm**

Cool - I was going to do it when I got back today but you beat me to it. I think Tidy is freely available, even though BBEdit costs money...

I can see how you'd scan the SXML for analysis:

Code: Select all

(define Tags:Tags)

(define (count-tags expr)
 (cond 
   ((list? (first expr))
      (count-tags (first expr))
      (dolist (s (rest expr)) (count-tags s)))
   ((symbol? (first expr))
      (dolist (s (rest expr)) 
            (count-tags s))
      (set 'key (string (first expr)))     
      (if (Tags key)
          (Tags key (inc (Tags key)))
          (Tags key 1))
      )
   )
)

(count-tags xf)

(println (Tags))
  (
    ("a" 2298) 
    ("align" 47) 
    ("alink" 1) 
    ("b" 150) 
    ("bgcolor" 1) 
    ("blockquote" 21) 
    ("body"  1)  
    ("border" 20)  
    ("br" 1079)  
    ("cellpadding" 20)  
    ("center" 42)  
    ("class" 2031)  
    ("color" 29)  
...

But presumably it's possible to actually execute the SXML list directly, provided that there are suitable functions already define for each symbol/tag...? How would I do that?

Posted: **Sun Mar 28, 2010 2:08 pm**

I tried to work out how to make such an SXML list can be an expression that can be directly evaluated. The problem is with the double-parenthesized expressions. For example, this is OK:

Code: Select all

(p "Built-in and user-defined functions are suitable for " (u "both") " types of arguments, but when passing context names, data will be passed by reference.") 
   (p "Quoted symbols can also be used to pass data by reference, but this method has disadvantages:")

because user-defined functions can be defined that output some representation of paragraph and underlined text. But I can't make these work:

Code: Select all

(a ((href "#load")) "load")

because of the double parentheses?

Posted: **Sun Mar 28, 2010 2:28 pm**

You need to add the SXML attribute tag '@' via option 16

Code: Select all

(xml-type-tags  nil nil nil nil)
(xml-parse "<a href='#thelink'>a Link</a>" 31)

=> ((a (@ (href "#thelink")) "a Link"))

Now the '@' could be defined as processing the s-expressions follwing it. Basically it would work like a 'begin'.

Posted: **Sun Mar 28, 2010 4:58 pm**

Yes - that works, thanks! Although now I've got even further into the jungle:

First I had to redefine the built-in symbols that also appear in the SXML, but then:

Code: Select all

(set-ref-all 'div xf '_div)
(set-ref-all 'name xf '_name)
(set-ref-all '@ xf '_@)

(define (_@) (begin (args)))

(map 
    (fn (f) 
      (letex
        ((fn-name (sym (string f))))
        (define (fn-name a) 
           (string a))))
    (map first (Tags)))

(println (apply eval xf))

it gives a stack overflow error... Nested too much? I didn't think so. I think I'm close to a solution but ...
