[NTG-context] xmlfiles and url address
Hi all,
I wish you happy new year and start with an xml-question:
Is it possible to process files from an URL address? It should be
something like:
\starttext
...
\xmlprocessfile{main}{http://example.com/document1.xml}{}
\xmlprocessfile{main}{http://example.com/document2.xml}{}
...
\stoptext
Thank you for your support. Kind regards,
Martin

\chapter{Preface}
To write Lecture Notes or Exams I want to use a mechanism
such that in just one paper the questions and the answers
can be written. And then to hide the answers at some way or
to get a coupling between the exercises and the solutions.\crlf
I wanted also a mechanism to give each exercise and each solution a number.
These numbers have not to be equal. It is may be better for the students that
numbers of the solutions are different from that of the exercises! Than they
can play the game: "What exercise belongs to a certain solution?"\crlf
The Zeroth Attempt: a try to use "coupling".\crlf
The First Attempt: the use of blocks, but the coupling explicit made by myself
and there is made use of \type{\defineenumeration}.\crlf
The Second Attempt: this I used already succesfully by texexec. I defined by
myself a new counter and used that counter in \type{\itemize} and I referenced
to
the \type{\item}(s).\crlf\crlf
Used is the frozen texexec "version 6.2.1 - 1997-2009 - PRAGMA ADE/POD" and
"version 2011.05.18 18:04", resp. "version 2012.01.02 21:59" of context. \crlf
On the way I learned howto work with a standalone ConTeXt and a system-wide
installed ConTeXt.

[NTG-context] CLD: context.getvariable as Lua variable
Hello,
I'm relatively quite new to TeX world. This is my first message to list. I
hope you understand me, English isn't my mother language.
I'm trying to use a variable set by \setvariable in Lua. I tried some
combinations, based on manual but I couldn't succeed. The code below
exemplifies what I wanted to do.
\starttext
\setvariable{namespace}{var}{Some context}
\ctxlua{
local s = context.getvariable("namespace", "var")
if s == "" then
...
else
...
end
}
\stoptext
I know that I can use some of \if* TeX commands, but coding in Lua is
better to me.

What you’re trying is not possible but there are other ways to check the
content of the variable in Lua.
\startluacode
userdata = userdata or { }
function userdata.checkvariable(variable)
if variable == "" then
context("EMPTY")
else
context("NOT EMPTY")
end
end
\stopluacode
\setvariable{wagner}{name}{Wagner Macedo}
\starttext
\ctxlua{userdata.checkvariable("\getvariable{wagner}{name}")}
% This does only with \startlua or \ctxlua
\startlua
local name = "\getvariable{wagner}{name}"
if name == "" then
context("No Text")
else
name = "Name: " .. name
context(name)
end
\stoplua
\stoptext
A different method is to save the \setvariables entries in a Lua table and
check the entries of the table.
\startluacode
userdata= userdataor { }
userdata.macedo = userdata.macedo or { }
userdata.macedo.data = { }
function userdata.macedo.savevariables(variables)
userdata.macedo.data = variables
end
function userdata.macedo.checkvariables()
local variables = userdata.macedo.data
-- check for name
if variables.name == "" then
context("Name: No name set")
context.par()
else
context("Name: "..variables.name)
context.par()
end
-- check for address
if variables.address == "" then
context("Address: No address set")
context.par()
else
context("Address: "..variables.address)
context.par()
end
end
\stopluacode
\starttexdefinition SaveVariables
\startlua
userdata.macedo.savevariables{
name= "\getvariable{macedo}{name}",
address = "\getvariable{macedo}{address}",
}
\stoplua
\stoptexdefinition
\setvariables[macedo][set=\SaveVariables]
\starttext
\setvariables[macedo][name=Wagner Macedo]
\ctxlua{userdata.macedo.checkvariables()}
\setvariables[macedo][address=Secret]
\ctxlua{userdata.macedo.checkvariables()}

Or use \em which (as I understand it) automatically adds italic correction?
Although the hybrid-italics feature looks great (so many hidden

Re: [NTG-context] CLD: context.getvariable as Lua variable
Firstly, thanks by answer.
The second way is nice, but could be generic (e.g. save any variable in a
namespace)?

[NTG-context] TeX inside XML
I need to do some ConTeXt work inside an XML-proces. In principle this works for most TeX-code through an appropriate xmlsetup that calls \xmlcontext. However some code has problems, and it will be no surprise that it concerns table suff. The error is: Misplaced \omit ... \@tbxmultispans #1->\omit \scratchcounter #1\relax \advance \scratchcounter … As this code runs fine in normal ConTeXt environments, the suspicion is some catcode problem. Can I set inside the \xmlsetup-code something to have \xmlcontext using the correct catcode's, iff that turns out to be the problem of course. Thanks in advance.

Don't worry. It's not needed. I just wanted to avoid mix Lua and TeX codes.
I will survive using:
local s = "\getvariable{namespace}{var}"

Re: [NTG-context] missing macro
In the meantime I have looked further into the problem. Although in the past redefinition of \Word was the only way to repair, this time there was a destructive interference with \startframedtext. It turned out that \startframedtext[align=middle, etc.] played havic with the following input, to the effect that \Word didn't work as expected. The simple solution --after some digging into my notes inside my (very) old copy of the ConTeXt manual-- was to always put the first set of brackets (even if empty) on the start: \startframedtext[][align=..] etc. Then the problem goes away, but I keep my fingers crossed ;-) No cause for calling "bug" therefore.

[NTG-context] How to define a command...
Hi all,
I need to define numerical coefficients (essentially at random) and then use
them with commands, say like \CoeffAlpha, \CoeffBeta, and so on.
More precisely, how can I define the command \RandomCoeff, so that
\RandomCoeff{Beta}{1}{10} yields a command named \CoeffBeta, which is a random
number chosen between 1 and 10?
I tried to use the following approach, but could not make it work:
%%% begin random-coeff.tex
\setuprandomize[2012] % set a seed
\ctxlua{CoeffAlpha = math.random(1,10) ;}
\def\CoeffAlpha{\ctxlua{tex.print(CoeffAlpha)}}
%
\define[3]\RandomCoeff{%
\ctxlua{a = math.random(#2,#3)}
% \csname{Coeff#1}\endcsname{\ctxlua{tex.print(a)}} %% this line does not
work as expected...
}
\starttext
\CoeffAlpha
\RandomCoeff{Beta}{1}{10}
\ctxlua{tex.print(a)}
%\CoeffBeta
\stoptext
%%% end random-coeff.tex
Thanks in advance for any suggestion or hint.
Best regards: OK

Don’t use a global namespace, you can use “userdata”.
userdata = userdata or { }
userdata.hvdm = userdata.hvdm or { }

Thanks Hans, in another problem I was looking for commands such as
\RandomRange, \RandomSeries: I am going to use your ideas!
It is incredible that on this list one gets solutions even for problems one
didn't dare to ask :-)

Re: [NTG-context] How to define a command...
Thanks for Wolfgang: your solution, that is
\setuprandomize[2012]
\define[3]\RandomCoeff{%
\setvalue{Coeff#1}{\ctxlua{tex.print(math.random(#2,#3))}}}
works indeed and it is somehow simpler than using \expandafter\csname, and as a
matter of fact, after reading your message I searched in the ConTeXt manuals
written by Hans, and found that \setvalue is defined on page 93 of
module-01.pdf as
\def\setvalue#1{\expandafter \def\csname#1\endcsname}
so it is better to use it.

Re: [NTG-context] How to define a command...
Hi again Wolfgang and Peter,
The solution you provided to my problem is great but has a small issue…
Considering the definition
\define[3]\RandomCoeff{%
\setvalue{Coeff#1}{\ctxlua{tex.print(math.random(#2,#3))}}
}
after saying
\RandomCoeff{Alpha}{1}{10}
one gets \CoeffAlpha, but if I use several times \CoeffAlpha, it takes a new
value each time, an effect which is undesirable in what I am willing to do.
Is there a way to somehow « freeze » the value of \CoeffAlpha once it is
defined?
Best regards: OK
PS: here is the complete example:
\define[3]\RandomCoeff{%
\setvalue{Coeff#1}{\ctxlua{tex.print(math.random(#2,#3))}}
}
\starttext
\RandomCoeff{Alpha}{1}{10}
\RandomCoeff{Beta}{10}{100}
\CoeffAlpha
\CoeffBeta
\CoeffAlpha
\CoeffBeta

Re: [NTG-context] How to define a command...
Sorry for the noise…
I found the answer to my last question in module-01.pdf, pages 92 and 93: the
right definition is
\define[3]\RandomCoeff{%
\setevalue{Coeff#1}{\ctxlua{tex.print(math.random(#2,#3))}}
}
that is one has to use \setevalue instead of \setvalue (that is \edef instead
of \def).

Hey Aditya. I tried both of those options, including altering \it to

\definefontfeature[default][default][itlc=yes]
\setupitaliccorrection[always]
All of the suggestions everyone kindly made appeared to have affected to
