[NTG-context] contextgarden.net
Hi, I have mentioned it at the last context conference: I am looking for a person (or a group) to take over the server contextgarden.net. Not only the wiki or the modules section or ..., but the complete server. I have started everything more then seven years ago and we (= you) have all made it possible that contextgarden.net is now used by more then 500 unique visitors each day (the wiki alone). The average time a user spends on the wiki is three and a half minute (according to the stats, but this is inaccurate, of course), I think that is pretty good! But as usual in a setting like this, I have shifted my focus. This does not mean I like ConTeXt less then several years ago! By no means! But I am too busy with my new job and my family so there is pretty much no server maintenance (except for a reboot once in a while). I really hope that someone steps in and I can hand over all the files/databases and the domain name before the next conference. Not that some parts are already maintained by other people: most prominently the minimals are done by Mojca with help of Arthur (I hope I've got it right).

This was just an example to show you how to use lua to do things which are
difficult or impossible or cumbersome in TeX alone, such as math, working with
strings (substitutions, etc.), conditionals, loops... You don't have to take my
code verbatim; the darkred was just meant to show that you can apply certain
code to a number if it matches a condition (here: be divisible by 5).
This gets me what I wanted. Still fumbling greatly with the macro
syntax. I'm not sure what the recursion is for, for example. On the
other hand the lua seems rather straightforward to me by comparison. I
tried returning an empty string like this: context.color( {blue}, ''
) to remove the other numbers, but that seemed silly, so I just
removed the 'else' clause instead, and that seemed to work as well.
Yes, of course, if all you want is process numbers divisible by 5, that's the
easiest way. But it's good to know that lua allows more complex conditionals -
you could use elseifs to make numbers divisible by 100 bold, or whatever. I
find such conditionals in TeX much more cumbersome; even for somebody with no
programming background like myself, they are easy to write in lua.
The recursion was just a way of demonstrating the effect. \dorecurse is a
wonderful macro to construct minimal examples (you can search the mail archive
for some real gems). And, as a hint: constructing a compilable minimal example
not only is educational (I don't know how often I could solve my problems when
I tried to produce a minimal example and saw where my approach was failing),
but will also improve your chances of people actually willing to help you. If
you want to see an elegant way of producing minimal examples in xml, search the
mail archive for xmlprocessbuffer.

Re: [NTG-context] Bug against minimals

Hi,
With latest stable minimals version I don't get correct output of the
metapost article (I attach it)
But with the texlive package with ubuntu 8.04 (and only with 8.04; with
10.10 I have the same problem), it works. I think it's a bug
Thanks,
Xan.
next make a small example
\starttext
\unexpanded\def\processword#1{\dontleavehmode\framed{#1} }
% fails, as recurse is not unexpanded (should it be?)
%
% \processwords{\phantom{\dorecurse{15}~}}
% \processwords{x x}
% \processisolatedwords{\phantom{\dorecurse{15}~}}\processword
% \processisolatedwords{x x}\processword
\stoptext
I wonder if that ever worked as \dorecurse is expandable and
processwords tests arguments.
Anyhow, in the latest mkiv you can use \processisolatedwords to do the
same. (In your case there are no words so you could apply your
\processword directly.)

Re: [NTG-context] why lua?
hans, some of the things you said are a bit unclear to me:
2010/12/18 Hans Hagen pra...@wxs.nl
Ah .. the extending vs the embedding debate ... well, an argument could
have been that we don't want to extend python -)
see last paragraphs.
I've only used Pascal, Modula2, Perl (after all that compiling and linking I
loved the scripting aspect but the language ... well ...), Ruby (brought me
back happy Modula memories but it got so huge and had incompatible updates
but is still my second choice), but I feel quite happy with Lua now.
give python a try. i love it because it has the writability of perl without
(de)referencing and funny symbols, and a class system like java/c++/… (no
prototyping and stuff)
well, i just like it. and since i don’t know lua (well, that’s not exactly
true, but i can’t write a normal sized script without looking things up),
and tend to do things like i would do them in other languages i know. e.g.:
how do you loop elegantly over table values? “for k,v in pairs(t) do print(v)
end” creates a throwaway variable k, which doesn’t seem right. some things
are totally counter-intuitive for me like tables beginning with index 1, and
so on.
so i guess it’s natural that i would like to use a scripting language i know
and like, like python.
Anyhow, I don't like languages that need religious arguments to become
popular.
like… which one? i only know of the tabs vs. spaces and vim vs. emacs
religious wars. i can’t remember of any languages being subdued to that.
or are you talking about lua having been invented at a catholic university
and thus being a product of a sect somehow?
Hans
what i want to show you is krosshttp://en.wikipedia.org/wiki/Kross_%28KDE%29
.
kross is the project for bringing consistent scripting to KDE, and it is
just awesome, since it allows you to write stuff in the scripting language
of your choice.
my dream for luatex/context would be a built-in lua interpreter (because lua
is so fucking small) and optional modules for other, heavier, scripting
languages (perl, ruby), which you don’t have to install. i don’t care if
python is embedded or extended, i just want to write \directpython{for num
in [9,2,4,8]: ctx.print(num**3)} (or sth. like that)
but don’t get me wrong, i love context and luatext, i just like other
languages better than lua (you weren’t content with latex and created
context, so this shouldn’t be alien to you)

luatex is more than lua (or any prog/scripting language) embedded in tex;
it is a programming language with acess to tex's internals. For example,
you can find the dimension of each node in a vlist and use a different
line-breaking algorithm or tweak the node list after line breaking is done
(something like this is done in arabic line-breaking). If you do not
want easy access to tex's internals, embedding/extending tex is relatively
easy: see for example perltex. Whether the binary of the prog language is
embedded in the tex binary, or in the wrapper script for calling tex is
immaterial. On the other hand, if you want acess to tex's internals, you
can either code it for a specific language (like luatex does), or provide
an API interface to the internals. My understanding is that given the
complexity of the tex codebase, the latter was more too much effort for
too little gain. After all, python vs lua is a minor difference, compared
to the programing abilities of TeX.
