[NTG-context] Creating TeX dimensions and counters registers directly in Lua
Hello all,
Is it possible to create a new dimension ConTeXt register directly in
Lua, or I have to first create the ConTeXt dimensional register and then
to subsequently assign it a value?
Here is example:
\starttext
\newdimen\mydimension
\directlua{tex.setdimen(mydimension, 123)}
\stoptext
works fine, but all like:
\starttext
\directlua{tex.print([[\newdimen\myotherdimension]])}
\directlua{tex.setdimen(myotherdimension, 123)}
\directlua{tex.newdimen(myotherdimension)}
etc...
\stoptext
fails.
In addition, I am interested in whether directly in Lua to create a new
counter as in the previous.
\starttext
\newcount\mycount
\directlua{
tex.setcount(mycount,125)
}
again works, but anything like:
\starttext
\directlua{tex.print([[\newcount\myothercount]])}
\directlua{tex.newcount(myothercount)}
etc...
\stoptext
again fails...
Is there any source or examples to study anything about it?
Thanx Jaroslav

AFAIK there is no tex.setdimen but what’s the problem to use Lua tables to save
the values.
\starttext
\ctxlua{mydimension = number.topoints(1)}
\ctxlua{context(mydimension)}
\blank
\ctxlua{myotherdimension = 123456}
\ctxlua{context(number.tocentimeters(myotherdimension))}
\stoptext

Re: [NTG-context] Struggling with ConTeXt
Thank you for the tips.
Here, I cleaned up the code some more (sorry to have left stuff over
last time),.
I added some explanations to make my issue clearer
\startusableMPgraphic{myFrame}
draw OverlayBox withpen pencircle scaled 1pt withcolor green;
draw (currentpicture enlarged 2cm) withcolor red withpen pencircle
scaled 2pt;
\stopusableMPgraphic
\defineoverlay[myOverlay][\useMPgraphic{myFrame}]
\defineframedtext[myStatement][frame=off]
\setupframedtexts[myStatement][background=myOverlay,offset=overlay,autowidth=force]
\starttext
\framed[strut=no]{\startmyStatement FIRST TEST\stopmyStatement}
In the first test, I would like the black box to have the dimensions of
the red box.
\blank[big,big,big,big,big,big,big,big,big,big]
\placefigure[left,none]{}{\startmyStatement SECOND TEST\stopmyStatement}
In the second test, I'm going to demonstrate the issue by flowing text
around the framed text, the green color {\em and the red color}
shouldn't touch the flowing text as I want the float box to include the
text box {\em and the overlay box.}
Best regards,
Olivier

Thanks Wolfgang for the reply,

Thanks for the help. But I'm affraid that this won't do as I won't
know/I am not supposed to know the dimensions of the bounding box of the
overlay I'll use.
:/
For the sake of the minimal example, I only enlarged the picture by 2cm,
but in real production situations,
the bounding box is going to be enlarged by random offset, because the
overlay will have various parts with weird shapes (super ellipse,
squeezed rectangles) that go beyond the original text boundaries (like
in the Zapf frametext example of the Context manual : the title is
protruding out of the main box and if you put weird stuff in there, you
won't know the dimensions).
I don't want to manually calculate those offsets, I would like metapost
to pass it's bounding box dimensions for the overlay to context so that
it automatically applies the correct offset to the text+overlay
]{\myStatement{SECOND TEST}}}
If needed, you can hide this behind macros:

[NTG-context] Ctx ... Lua
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 \cldcontext{} does?
TIA.

Re: [NTG-context] Creating TeX dimensions and counters registers directly in Lua
Thank to Hans and Peter too.
It works in context fine now. I would like realize this same in pure LuaTeX.
I was primarily in the query for it to find Lua equivalent of TeX
primitives \newdimen and \newcount (for direct creating new TeX registers)
I could use something like \directlua{tex.newdimen.mydimen} that would
create TeX register mydimen and then
\directlua{tex.dimen.mydimen=200*2^16} which set value of register and
that should be present in TeX for direct use such as \the\mydimen etc.
I apologize for my naivete :-).
Of course, I did not think that the global variable is magically changed
the registry value, I just did not know how to implement it.
Plus, I had in mind that ConTeXt conversion functions do not work in a
clean LuaTEX (without reading about some library functions).
One more thanx.
Jaroslav
Here is my pure luatex example. Is there any easy way?
\newdimen\mytexdimension
\mytexdimension 100pt
mytexdimension: .\hbox to\mytexdimension{\the\mytexdimension}.
\directlua{tex.myluadimension = 200pt}
myluadimension: .\hbox to
\directlua{tex.print(tex.myluadimension)}{\directlua{tex.print(tex.myluadimension)}}.
\directlua{tex.dimen.mytexdimension = 300pt}
mytexdimension: .\hbox to\mytexdimension{\the\mytexdimension}.
\def\myluadimension{\directlua{tex.print(tex.myluadimension)}}
myluadimension: .\hbox to\myluadimension{\myluadimension}.

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 for
\ctxlua{context}
All these commands access functions in the “commands” or the “context”
namespace.

[NTG-context] Lua: document v. userdata

Sure. Actually the document namespace has some functions so there is
more danger in a clash there, so userdata is better.

Re: [NTG-context] Creating TeX dimensions and counters registers directly in Lua
Great!!!
Thanx very much Hans...
Normally I do all things in ConTeXt, but I am preparing a beginning
tutorial for users of LaTeX and PlainTeX, who would be interested in
getting to know the basics LuaTEX. Therefore I am seeking a solution
applicable in LuaLaTeX and LuaPlain too.

Just do:
tex.dimen[20001] = 100pt
at the lau end and at the tex end:
\dimen20001=100pt
keep in mind that \newdimen is just an allocator that associates a \cs
and the implementation of that is pretty macro package dependent!
Starting at 2 makes sure that you have no clash with existing
registers.
Of course, I did not think that the global variable is magically changed
the registry value, I just did not know how to implement it.
Plus, I had in mind that ConTeXt conversion functions do not work in a
clean LuaTEX (without reading about some library functions).
Ok, but keep in mind that clean luatex does not exist. As soon as one
starts doing things at the lua end that reflects on the tex end, you
have a dependency.
I will add a context.newdimen function so that one can do:
\startluacode
document.mydimen = context.newdimen(MyDimen)
tex.dimen[document.mydimen] = 10pt
\stopluacode
\the\MyDimen
\MyDimen=100pt
\the\MyDimen
\startluacode
context(number.points(tex.dimen[document.mydimen]))
\stopluacode
Posting the implemenation makes no sense as it refers to low level
context properties that users should not be troubled with.
PS. From the context point of view I see no advantages of using plain.
First of all, one can still do pretty plain things in context.

[NTG-context] built-in units command (mkiv) fails
Hi there,
Did / Do I miss something or is there a problem with the built-in \unit command?
minimal example:
start example
\starttext
10 \unit{km/h}
\stoptext
stop example
output:
10 kilometersolidushour
ConTeXt:
ver: 2012.08.16 22:20 MKIV fmt: 2012.8.22
Similar results are obtained for all examples in the Using the built-in
command on http://wiki.contextgarden.net/Units
Cheers,
Andreas

Re: [NTG-context] Code in contextref-env.tex
I have no idea what the sequences like \v!and \c! etc. mean. Are they references to modes? I asked much the same question on tex.stackexchange.com two months ago, except mine was not so nice and focused. Aditya gave a very nice explanation of what the letters do; clearer than the one on the wiki, I thought. Here's a link straight to his answer: http://tex.stackexchange.com/a/58716/2229 They are used as language-agnostic forms. Using ConTeXt's English format, you'd type \startmarginblock Using ConTeXt's French format, you'd type \demarreblocmarge So to accomodate both, we define variables \s!start -- start or demarre, and \e!marginblock -- marginblock or blocmarge, depending on the language, and then we tell TeX we want to run the command named with the string \s!start\e!marginblock -- startmarginblock or demarreblocmarge. (Example not entirely accurate, I believe the variable for startmarginblock is define holisticaly. But you get my point.) Example of the need for the letter codes, paraphrased from mult-ini.mkiv: Where English uses 'left', in Dutch one finds both 'links' for '(on) the left' and 'linker' for 'the left one'. Hence the letter codes, so we can have \v!left -- links and \c!left -- linker. \c! is for keywords \v! is for value names \s! is for system bits \e! is for elements Hope this helps you in reading the sources!

[NTG-context] mp
Hi,
In the next version you can run mp files:
% test.mp
beginfig(1) ;
fill fullcircle scaled 10cm withcolor 0.5red ;
fill fullcircle scaled 4cm withcolor 0.5white ;
endfig ;
beginfig(2) ;
fill fullcircle scaled 10cm withcolor 0.5green ;
fill fullcircle scaled 5cm withcolor 0.5white ;
endfig ;
beginfig(3) ;
fill fullcircle scaled 10cm withcolor 0.5blue ;
fill fullcircle scaled 6cm withcolor 0.5white ;
endfig ;
as follows:
context test.mp
and you'll get a pdf file with 3 pages that can be included with
\externalfigure[test][page=1]
\externalfigure[test][page=2]
\externalfigure[test][page=3]
or used in different ways. Alteratively you can run
% test.tex
\starttext
\processMPfigurefile{figures-001.mp}
\stoptext
In which case you can add styling directives in the preamble.

In practice users don't have to use that convention in their files, unless they are meant to be multilingual. Btw, there is a nice story behind this: - left= 4 tokens - \c!left = 1 token so, when context grew harder than tex's string space (we're talking emtex times) it was also a way to save memory. To some extend it's also faster (less tokens to pass as argument) but at the same time there is a penalty of expanding the 1 into 4. So, in a single lingual interface there is not much gain. Some of the 'struggles with too small engines' has been removed in mkiv as nowadays we have no such constraints. When I introduced the \c! and \v! prefixes context was still dutch and when there came interest from abroad, it had the nice side effect that I could make an (first german, later also english) interface in just a couple of hours (context was smaller at that time). The first module to actually be multilingual was 'ppchtex'.

Nice. How is font setup handled? Using verbatimtex ... etex? Or using the
styling directives as you explain below.
Would something like
context --environment=font-setup test.mp
work?
or used in different ways. Alteratively you can run
% test.tex
\starttext
\processMPfigurefile{figures-001.mp}
\stoptext
In which case you can add styling directives in the preamble.
