[NTG-context] Re: listings.sty
Hello Peter, I suggested to the author of the very feature rich LaTeX-Listings package, Carsten Heinz, to port this package to ConTeXt, and it seems, that he is interested. But before doing it, there are some questions: * What do Hans and other people thing about that? Hmm, I never use listings.sty with LaTeX. Once I used the ConTeXt variant of listings.sty. Perhaps the ConTeXt built in support for listings is sufficient. * listings.sty uses keyval.sty, how is the proper ConTeXt-way to do the same things as keyval, or should listings stay with keyval? I'd suggest to go for the ConTeXt specific. I could help with it. See syst-gen.tex and syst-ext.tex for details on the macros for a=b kind of assignments in ConTeXt.

Hi, Also, this could be the url for hight level FAQ (this forum it not realy a hight level forum!) Go ahead and put it in the wiki! Its up to us all to put content in there. - how about ConTeXt future (why it is not open source?) It is open source, even free software. You can go ahead and change everything yourself. Pragma ADE has licenced this impressive and valuable macro package under the terms of the GNU Public License (GPL)! This is really great! (See mreadme.pdf for details.)

[NTG-context] High level user macro (howto?)
Bonjour à tous,
One thing is missing in context (or not documented in reference manual?)
is a standard and easy way to build arbitrary parametrised high level
macros.
For exemple, instead of
\def\myCommand#9{...}
That I should call by
\myCommand{param1}{param2}{...} {param9}
Id'like too keep default value for most of the parameters but param7
and write something like:
\myCommand[param7=value7]{body}
In LaTeX, there is a package keyval for doing this
And context use this everywere, but I haven't seen anything for
a user beeing able to do this.
This is the base for building arbitrary complex user commands with
some defauld behavior, and then, if this personal macro is usefull
enough, building some user contribution library.
As a true exemple, see a latex package I've written some years
ago for drawing uml diagramms whith LaTeX command (using PsTricks).
This file is available at
http://www.ensta.fr/~diam/latex/pst-uml/pst-uml-981218-09h41.tar.gz
(should now be available on CTAN too)
See documents for the samples (in french but the samples are in LaTeX
and
drawing are in picture !)
One of the first exemple I'd like is some command to put some little
table as caractere in a line (see that as some personalised box):
start of line
$-$\myStack[border=1ex,baseline=0.5]{
aaa bbb \\
aaa bbb \\
aaa bbb
}$-$
end of line
Or a little command to draw some picture, with default but modifiable
parameters:
$-$\myzigzag[dir=down,linewith=1pt,color=red,with=3\em]$-$
Using Metafun.
Cordialement,
-- Maurice

Hello, I suggested to the author of the very feature rich LaTeX-Listings package, Carsten Heinz, to port this package to ConTeXt, and it seems, that he is interested. But before doing it, there are some questions: * What do Hans and other people thing about that? what is listings.sty providing? listings.sty is one of the very few packages from LaTeX, which I am still missing in ConTeXt. I yet never extensively used the listings functionality provided by ConTeXt, but from what I remember from reading the documentation, the liststings.sty is much more flexible. It has an easy interface to define new languages (like Opal, a functional programming language used in courses at my university), allows flexible line numbering (all, every n lines), it allows customization of all fonts (line numbers, keywords, comments, ...), indenting, ... Most importantly for me: It allows easy escaping to TeX. One option is to interpret all comments as (La)TeX code. This was very useful for typesetting correctness proofs of programs using the Hoare Calculus, because it makes such listings much more readable. Then there are other niceties already provided by ConTeXt, like frames, floats, etc. Oh, one other nice thing is, that it allows to use proportional fonts (is that the right translation? I mean non-fixed width fonts), and still can keep indentations correctly, e.g. with assignments like alongvariable = 1; short = 2; I think the algorithm is described a little in the documentation. As far as I remember, it assumes a (configurable) average character width of proportional fonts and typesets every word in a box of the width corresponding to the number of characters included in the word. These were at least the features most important to me ... -- Holger F. Schoener TU Berlin; Dept.

[NTG-context] Extending metapost
Hi Hans, group, I saw this passing by in another thread, and since I am myself currently working on a C port of metapost: (and ... i also want to look into extending tex and metapost) What kind of extensions to metapost do you (or anyone else) have in mind? Progress update: Work on the C port of MP is coming along nicely. Work progress is fairly slow because I have to make change quite a lot of small changes to the code. I expect to have a 'working' test executable in about 3 or 4 weeks. libMP will have (at least) the following changes wrt. the Web source code: - C strings instead of a string pool ( and no pool file). - A struct METAPOST instance that gets moved around, instead of global variables (libMP will be thread-safe) - A namespace for all externally visible procedures and enums (prefix 'mp') - mp_initialize() and mp_finish() calls to allow clean restarts. - All file I/O will be configurable (through callbacks) - PostScript output will be isolated from the other output. (to allow other output backends in the future). -- groeten, Taco ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

It is true, we need a programming in ConTeXt manual. It is
still possible to 'know' how to do things by looking at the way
things are done in ConTeXt itself. For example, in your case
you want something like this:
\def\myCommand[#1]#2{%
\rawgetparameters[myCommand][param1=defaultvalue1,param2=defaultvalue2,#1]%
do something with \csname myCommandparam1\endcsname and #2}
This is of course very draft, and can be highly tuned and done
multilingual, but that's much more complex.

Re: [NTG-context] High level user macro (howto?)
Hi Maurice,
The 'key' to the keyval functionality in ConTeXt are two macros called
\getparameters and \processaction.
Here is a 'quickstart', assuming you want to define \myzigzag:
%
\unprotect % enable exclamations in macro names
\def\myzigzag#1[#2]{%
% the #1 makes sure we allow a space before the bracket
%
\getparameters[ZZ][Dir=,Linewidth=1pt,Color=Red,Width=3em,#2]
%
% Now you have a set of new macros that all start with ZZ.
% At least there are \ZZDir,\ZZLinewidth, \ZZColor and \ZZWidth
% (these have default values) but possibly others as well,
% depending on user input.
%
% Here's a usage example:
%
\edef\mywidth{\ZZWidth}%
%
% If you want to use keyword values, then you also need
% to use \processaction.
%
% Say you want Dir to be mandatory and that it
% accepts 4 directional keywords, as well as a direct
% angle specification.
%
% I've used all mixed case keywords, because otherwise
% you might run into conflicts with the multilingual interface
%
\expandafter\processaction\expandafter[\ZZDir]
[Down =\def\Dir{270},
Left =\def\Dir{180},
Up =\def\Dir{90},
Right =\def\Dir{0},
\s!default =\errorDir,
\s!unknown =\checkDir{\ZZDir}]
%
% \s!default may be triggered because \ZZDir's expansion is
% empty unless the user supplied something.
%
% The first argument to \processaction has to be expanded,
% so you need the \expandafter's.q
}
% for completeness, here is an example definition of \checkDir and
% \errorDir:
\def\errorDir{%
\def\Dir{0}% error recovery
\message{Please supply Dir argument}%
}
\def\checkDir#1{%
\doifnumberelse {#1}
{\def\Dir{#1}}
{\message{Invalid Dir argument! (#1)}}
}
\protect % end of definitions

There is
\setvariables [yournamespace] [yourvar=yourval]
which operates independent of the language interface
\getvariable{yournamespace}{yourvar}
can be used to pick up a var
The most important issue here is that you need to use some unique prefix, preferable something MyPrefix (capital and verbose).

Hello Hans, here some features of listings.sty: - support for a lot of languages (for example C) - easy to add further languages - line breaking (see my email from 19.

A verbatim environment is tricky because one has to play with catcodes and the endcondition. There are also some spacing issues when used in combination with other macro package features. Another complication is that active characters are used for other features as well. I had put it on my todo list to reimplement some of the context verbatim features using etex (more robust and faster).

One potential problem with third party modules is that they set tex variables without context knowing about it.

Yes, for such features the LaTeX built in mechanisms are used (for example
\addcontentsline{lol}{lstlisting}{...}. Here the LaTeX interface must be
replaced by a ConTeXt interface.
If some features are missing in the current verbatim environment (one of
the older parts of context) i can add them if needed. On the other hand,
it does not hurt to have multiple alternatives.
In general, the users prefer one solid way to go, instead of multiple
choices but each one with missing features.
If you want to rewrite the verbatim environment anyway, perhaps it's the
easiest way to take listings.sty as starting point?
Personally for me, today I'm just looking for two features:
- line breaking as suggested in my email from 19. June (- \hyphenatedfile)
- support for C and C++
