Hi Philipp,
Thanks to you, Dalyoung and Hans for the nice example using luacode.
I was wonedring how would you modify your code in order to be able to change
the name of the matrix if necessary. For instance, how to modify your code in
such a way that upon saying
\ctxlua
that upon saying
\ctxlua{document.print_matrix(b,3)}
one gets a 3x3 matrix whos coefficients are b_{11},…b_{33}.
if the two of you can come up with some specs we can make a small module
if needed
Hans
to modify your code in
such a way that upon saying
\ctxlua{document.print_matrix(b,3)}
one gets a 3x3 matrix whos coefficients are b_{11},…b_{33}.
Thanks in advance: OK
Something like this?
·
document.print_matrix = function
in
such a way that upon saying
\ctxlua{document.print_matrix(b,3)}
one gets a 3x3 matrix whos coefficients are b_{11},…b_{33}.
This may be overkill but you can just wrap the matrix command in
some TeX macro:
·
% macros=mkvi
and column
context.NC(string.format(schema, i, j))
end
context.NR()
end
context.stopmatrix()
end
\stopluacode
\starttext
\startformula
\ctxlua{document.print_matrix(3)}
\stopformula
\startformula
\ctxlua{document.print_matrix(9,4)}
\stopformula
]
{\iffirstargument
{#left }%%
\fi
\ctxlua{userdata.inwithranges(#label)}%%
\ifsecondargument
{#right}%%
\fi}
Then you can write:
See \inrange{figures} [fig:a,fig:c,fig:d,fig:e,fig:g,fig:x,fig:h]
See \inrange{figures}{TT} [fig:a,fig:c,fig:d,fig:e,fig:g,fig:x,fig:h]
See
functions sometime this weekend. But they
should be doable, really. (And, of course, you may be far more
experienced in LuaTeX than I, I don't know.)
Cheers,
Sietse

Hello,
sometimes in this mail discussion I'm encountering a Ctx/Lua command which has
been unknown for me or I would use other (known) commands to do the job.
So - would it be possible to explain
- what's the difference/advantage btw \directlua and \ctxlua
- what \ctxcommand{} does
- what
converting
functions do not work etc. ..

No difference, just another name, there are even more synonyms.
- what \ctxcommand{} does
\ctxcommand{...} == \ctxlua{commands}
- what \cldcontext{} does?
\cldcontext{...} == \ctxlua{context(...)}
There is also \cldcommand{...} which is a short form

The \ctxlua variant is somewhat more future proof. In the past
\directlua had a mandate extra argument. Also, the \ctxlua macro

You can also write your own stop/stop-commands for the document like
\def\startmydocument
{\starttext}
\def\stopmydocument
{\ctxlua{…}%
\stoptext}
and use them instead
{\ctxlua{…}%
\stoptext}
and use them instead of \starttext and \stoptext.
Or you use the predefined document environment which has before and after keys.
\setupdocument[after={\blank\midaligned{\bf THE END}}]
\startdocument
\input knuth
\stopdocument

Why don't you use the first version (\initializebazaarversion and
\usebazaarversion)?
\def\initializeBazaar
{\ctxlua{context(\\global\\edef\\BazaarRevision{\%s},
os.resultofbzr revno | tr -d '\\n')}}
\initializeBazaar

\appendtoks \initilizebazaar \to \everystarttext
and then use can use \usebazaarrevision in the main text.
If you want to use the automagic way, you can define \BazaarRevision

Can you please someone help?

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
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
Reccently I did something random in ctxlua. I post it in the hope it will be
useful.

Don’t use a global namespace, you can use “userdata
