sorting commalist?

sorting commalist?

[-- Attachment #1.1: Type: text/plain, Size: 610 bytes --]

In the article "Context System macros, part1: general macros" there  
are all sorts of interesting and useful macros. Among these I have  
set my eye on the processing of commalists.
Question: is there a context macro that takes a commalist (either in  
a token register or \the\tokenregister form) that returns a sorted  
commalist (ascending or descending doesnt matter to me for the moment).
If someone will be so kind to point one out to me. A scan through the  
sources didn't bring an obvious candidate to my attention although I  
feel there must be one, but I may overlooking it.

I should extend that document, but I've lost the source :-(

There is \sortcommalist (syst-ext.tex), but it only works for lists
of numbers, TeX does not know how to sort words. That type of sorting
has to be done externally.

Considering this document very useful I had an idea of puting at least 
parts of it on garden. So shoud I extract the texts, make some formating 
and send it to you or put it on the wiki?

The wiki would be great. That way, if I do not get around to doing
work on it, someone else can.

TIA,
Taco

Well, losing the source of the first article is not such a problem as  
finishing the second one, I guess :-)

Is there a simple manner to sort the list externally and get it back  
for further processing? Otherwise, how are the indexes sorted?

Externally, using texexec functionality. Something like this
works well enough, I guess (but I normally sort my stuff by
piping it through the unix sort command):


% This sorts the list contained in it's argument
\def\sortalphacommacommand#1%
   {\definesorting[listsort][listsorts]%
    \processcommacommand[#1]\listsort
    \def\sortedcommalist{}%
    \def\makesortedlist##1%
        {\doglobal\appendtocommalist{##1}\sortedcommalist}%
    \setupsorting[listsort][criterium=all,command=\makesortedlist]%
    \placelistoflistsorts
    \let#1\sortedcommalist}


\def\citylist{Londen,Berlijn,New York,Parijs,Amstelveen}

\sortalphacommacommand\citylist

Done. http://wiki.contextgarden.net/System_Macros

The page is rather long. I leave to experienced users who are going to 
extend the article to rearrange it, if needed. Hopefully it still 
remains Taco's article, who will write part II soon ;)



Few notes for Patrick et al. regarding wiki.

1. I've found strange writing

<code>\contextversion</code> (with backslash)
<cmd>contextversion</cmd>    (without backslash)

this may lead to errors, in my opinion, syntax should be the same (with 
backslash). I'm not sure, if there is any chance to change it on the fly 
everywhere nor if it is possible at all.

2. <cmd> elements should point only to context user macros (not to TeX 
primitives nor ConText internals), right?

3. I didn't notice before that even in-line element <code> is 
highlighted in backround as the block element <texcode> is. On my 
display it is almost invisible as a part of line. If we want to 
highlight I suggest to use a bit darker or different color. Now it is 
somewhere in the middle: highlighted as well as not highlighted (dust on 
the screen).

Great, thanks for that work!
