[NTG-context] error when using externalfigure
Hello,
I have a big context source file which contains pictures from different
sources. The problem is, that there are some pictures the context cannot
process. It displays an error message and ends. I run the context from
another script in batchmode. After finishing, the context creates a PDF
file, which contains this problematic picture but the pdf is broken. It
does not have numbers in the table of contents and it is not arranged by
setup.
Here is a minimal example:
\starttext
\externalfigure[
http://cdn-locations-images.tripomatic.com/img-poi1295-5ZTynx-s.jpg][width=26.5mm
]
\stoptext
When I run the context, it prints:
! Dimension too large.
system tex error on line 1 in file a.tex: Dimension too large
...

2 \externalfigure[
http://cdn-locations-images.tripomatic.com/img-poi1295-5ZTynx-s.jpg][width=26.5mm
]

\relocateexternalfigure ...d \foundexternalfigure

\dodoplaceexternalfigure ...[][#1][#2][#3][#4][#5]
\dotagfigure \naturalvbox
...
argument ...1295-5ZTynx-s.jpg][][width=26.5mm][]
\fi
\firstofoneargument #1-#1
Because I have several thousands pictures, it is impossible for me to
correct them all. Is it somehow possible to run the context so that it
ignores the problematic pictures?
Thank you
Pavel Dohnal

[NTG-context] print context version
Hi all,
this is a very easy one, but I couldn't find information: for a document
under version control, I would like to typeset the git revision and the
context version used in a footer. For git, I have come up with
\starttext
git revision \ctxlua{context(os.resultof(git --no-pager log
--pretty='\%h of \%aD' -1))}
\stoptext
But what is the easiest way to typeset the context version? There must
be something easier than
\ctxlua{context(os.resultof(context --version | grep current))}, right?
All best
Thomas

[NTG-context] \externalfigure and large-paged pdfs
Hi,
Actually, this is a bug report. If you try to include a pdf with a large
page size:
\starttext
\externalfigure[plankaart]
\stoptext
chances are that you get an error message like this:
! Dimension too large.
recently read \hsize
\setraggedness ...yphenpenalty \dimexpr 2.8\hsize
/\dimexpr #1\relax
\relax ...
\raggedcenter ...spac_align_set_raggedness_middle

{\vfilll \box
\foundextern...
\grph_include_place ...ode \grph_include_finalize
\fi \ctxlua
{figures.pop()...
...
l.2 \externalfigure[plankaart]
It seems that \externalfigure forces execution of \raggedcenter, and if
your PDF's page is large enough, that then fails.
There is, in fact, a workaroud:
\starttext
{\setupalign[nothyphenated]\externalfigure[plankaart]}
\stoptext
but that looks totally bizarre. Hans, can you find a way to fix this
properly?
Best wishes,
Taco

Re: [NTG-context] using variable for subscript in math+lua
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{document.print_matrix(b,3)}
one gets a 3x3 matrix whos coefficients are b_{11},…b_{33}.
Thanks in advance: OK

Dear Hans, Lucas, Wolfgang, Aditya
Now, I write a matrix using \startluacode by the helps of you.
Also, I can do some operations in matrices which reduced my typing job.
In this code, I have to give all the entries of a matrix as a table. It is
good to use in many cases.
I have one more question. If the given array is as the following and it
works well.
However, there might be a better way to do job using for iteration.
I tired to use i, j in several ways but it doesn't work.
Inside a string the variables are just bytes. To print to a
string you can interpolate with string.format() [1].

context.startmatrix{left = \\left(\\,, right = \\,\\right)}
local schema = a_{%d%d} -- %d: prints integer part
for i=1, x do
for j=1, y do

This may be overkill but you can just wrap the matrix command in
some TeX macro:

commands.matrix_with_symbol = function (sym, x, y)

context.startmatrix{ left = \\left(\\,, right = \\,\\right) }
local schema = sym .. _{%d%d} -- %d: prints integer part
for i=1, x do
for j=1, y do
context.NC()
context(schema, i, j)
end
context.NR()
end
context.stopmatrix()
end
\stopluacode

\fi
\ctxcommand{matrix_with_symbol(\!!bs\sym\!!es, \x, \y)}%
\egroup%
}
\protect
\starttext

\printsymbolmatrix[3]%% symbol is “a”, matrix is square
\stopformula

\stopformula
\startformula
\printsymbolmatrix[c][5][3]%% symbol is “c”, matrix is 5x3

Now the symbol will default to “a” but you can specify another
one. (Btw. I think the Lua part could be done as easily with
dorecurse.)

Philipp

Re: [NTG-context] Referring to multiple elements
2012-09-28 Sietse Brouwer sbbrou...@gmail.com:
Hi Sietse,
\in{figure}[alpha,beta,gamma]
This outputs “figure 1”. What I'd like to have is “figure 1-3”.
The attached quasi-module seems to do it! On my computer, at least. (I
call it 'quasi' because it is really nothing more than code in a file
of its own.No configurability whatsoever, except to the extent that I
tried to comment well, and split things up into functions.) I'd have
written it so that it properly identifies runs like '1.2.1, 1.2.2,
1.2.3', too, but I can't find a function that will turn reference
strings into such a prefixed strings.
I hope it does what you want! Let me know if you want/need any
alterations, or discover bugs.
Thanks a lot for that. I'd adjust the interface, so that it matches
the behaviour of \in:
\def\inrange
{\dodoublegroupempty\doinrange}
\def\doinrange#left#right#dummy[#label]
{\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 \inrange [fig:a,fig:c,fig:d,fig:e,fig:g,fig:x,fig:h]
Maybe worth mentioning: You need the additional module
`showtable.lua` from http://article.gmane.org/gmane.comp.tex.context/78336

The heart of what you need is a lua function that will take an array
of numbers, and return an array of consective-number runs, like so:
fignumarray = {1, 2, 3,5, 6,8, 10, 11, 12}
-- figruns = get_runs(fignumarray)
-- returns a table structured like so:
-- figruns[1].start = 1, figruns[1].stop = 3,
-- figruns[2].start = 5, figruns[2].stop = 6,
-- figruns[3].start = 8, figruns[3].stop = 8,
-- figruns[4].start = 10, figruns[4].stop = 12
I've written one below, plus the scaffolding required to feed it the
right input, and print its output to ConTeXt. Only two functions still
need writing --- one to turn the context argument [fig:f1, fig:f2,
fig:f4] into a lua array of strings, and one to turn each reference
string into a figure number. But this should get you on your way.
If you're not comfortable with programming LuaTeX, say so and I can
fill in the two missing 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
% should be below startluacode block, but clearer like so
\def\inwithranges[#1]%
{\ctxlua{u.inwithranges(#1)}}
\startluacode
u = userdata or { }
function get_runs(a)
runs = { }
run_start = 1
while run_start = #a do
run_stop = run_start
while a[run_stop + 1] == a[run_stop] + 1 do
run_stop = run_stop + 1
end
print(a[run_start] .. - .. a[run_stop])
table.insert(runs, {[start] = a[run_start],
[stop] = a[run_stop]})
run_start = run_stop + 1
end
return runs
end
function u.inwithranges(ref_string)
-- CTX... means I expect ConTeXt already has this function in a
library somewhere
local ref_array = CTXstring_to_array(refs_string) --FIXME
local ref_numbers = { }
for _, v in ipairs(ref_array) do
ref_numbers[i] = CTXref_to_fignumber(array) --FIXME
end
ref_numbers.sort()
runs = get_runs(ref_numbers)
for i, run in ipairs(runs) do
context.in( {run.start} )
context(-)
context.in( {run.stop} )
if i #runs then context(',') end
end
end
\stopluacode

Hi all,
I have a question about xml processing and I think that what I want/need
can best be achieved by using lua code, but so far, I'm not really sure
how to proceed, so any help from one of the resident lua gurus would be
welcome.
So: the question. xml allows to provide elements with unique identifiers
so that one can add cross-references within the document structure. Here
is a sample xml file that shows what I mean:
document
bibitem xml:id=hagen2011
authorHans Hagen/author
titleThe Meaning of Life Is 42/title
journalThe Rhetoric of Mathematics/journal
date2011/date

bibitem xml:id=hagen2012

text
pThis has been successfully proven in papers by bib
ref=#hagen2011/ and bib ref=#hagen2012/./p
/text
/document
[Note: the TEI guidelines add the hash character in the attribute value
to such references, but after much googling, I'm still not sure if this
is standard or necessary or bizarre.]
So: at the point of the reference (which may be empty, like here, or
contain text), I want to refer back to the bibitems. The typesetting
engine should then be instructed to pick up the information, so that
this is, e.g., typeset as This has been successfully proven in papers
by Hans Hagen (2011) and Hans Hagen (2012).
My idea: since the xml:id attributes must be unique across the document,
it would be easiest to collect them into a lua table, with the xml:id as
key, so their content could be accessed and typeset later. But
unfortunately, I have no clue how to go about this... Could somebody
provide a pointer?
Thanks for your interest, if you've read this far!

Is it possible to create a new dimension ConTeXt register directly in Lua, or

works fine, but all like:

In addition, I am interested in whether directly in Lua to create a new

Is there any source or examples to study anything about it?
AFAIK there is no tex.setdimen but what’s the problem to use Lua tables to save

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”

[NTG-context] Lua: document v. userdata
In a recent thread, Hans used the document namespace, where I (naively)
expected userdata:
On Aug 22, 2012, at 6:32 AM, Hans Hagen wrote:
\ctxlua{document.myluadimension = 200pt}
Is there a reason not to use userdata.myluadimension? Or is
document.myluadimension safe, because myluadimension is almost certainly not an
entry used by ConTeXt? Is using document.myluadimension better style here,
in some sense? Somewhere I had gotten the idea that if a ConTeXt user wanted
to store something in Lua, they ought to store it in the userdata namespace.

Is there a reason not to use userdata.myluadimension? Or is document.myluadimension safe,
because myluadimension is almost certainly not an entry used by ConTeXt? Is using
document.myluadimension better style here, in some sense? Somewhere I had
gotten the idea that if a ConTeXt user wanted to store something in Lua, they ought to
store it in the userdata namespace.
Sure. Actually the document namespace has some functions so there is
more danger in a clash there, so userdata is better.

Re: [NTG-context] test for (negative) number
Thanks for all the answers so far. The 'doifelse' should do the trick. I
was hoping for a system macro, but if there is none, I have to program
it myself. :-)

Instead of calling context directly, you can make a script, that throws

the functions in the lxml namespace already print to context and return
no value so you effectively appends nil which is invalid
also, when used in a context run the default serializer is also piping
to context so if you want otherwise you need to prefix with xml://
(which is an indication that in principle there can be many variants)
here are some valid solutions (whatch the lxml.id):
\startxmlsetups xml:test
\xmlsetsetup{#1}{c}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:test}
\startxmlsetups xml:c
\ctxlua{title = test= ..
xml.filter(lxml.id(#1),xml://./attribute(title)) context(title)}
\par
\ctxlua{context(test=)
xml.filter(lxml.id(#1),./attribute(title))}
\par
\ctxlua{context(test=) lxml.att(#1,title)}

[NTG-context] Struggling with ConTeXt
Hello
I'm trying to port a big 300+ pages math course full of macros from
plain XeTEX to ConTeXt mark IV (ubuntu 12.04+ stand alone beta)
and I'm having some difficulties, could you please help ?
My questions :
1) does lxml.att(#1,some tag) really work ?
the next snipet doesn't work for me:
\startluacode
function set(node)
p = lxml.att(node,p) -- or p = lxml.att(lxml.id(node),p)
end
\stopluacode
\startxmlsetups xml:section
\ctxlua{set(#1)}
\stopxmlsetups
it looks like it returns the p attribute of the node before #1
the following snipet works though (which is strange because I looked in
the context source and it gives
\def\xmlatt#1#2{\ctxlua{lxml.att(#1,#2)}}...)
\startxmlsetups xml:section
\ctxlua{p = \xmlatt{#1,p}}
\stopxmlsetups
2) I'm trying to export to xml and have set
\setupbackend[export=yes, xhtml=yes, css=mkiv-export.css]
But
a) my Metafun/Tikz pictures aren't exported to svg :/
b) the exported xml has namespaces problems (like error on line 63 at
column 20: Namespace prefix m on math is not defined error on line 64 at
column 22: Namespace prefix m on mrow is not defined)
What am I doing wrong ? (I'm compiling with context mydoc.tex)
Is there some \csname tex4ht\endcsname command or some other directive
that I should use to get my xml export right ?
Am I missing some namespace commands (there are lots of m:math and
m:mrow mathml tags int the exported xml source, this smells like a
tex4ht issue)
3) I have defined some framed text with metafun overlays (like in the
Context manual)
and I'm trying to type something like
\inmargin{some label}
\startMyFramedText...\stopMyFramedText
Yet, the text in the margin is after the framed text :(
(fiddling with the location setting (low, ..) doesn't allow me to have
the in margin text right next the top of the framed text
I somehow found a dirty workaround with typing a blank space
\defineframedtext[Property][frame=off,background=OverlayProperty,before={}]
and
\inmargin{some label}\noindent\startMyFramedText...\stopMyFramedText
but it's not really satisfying. (hate to lose vertical space with
wandering blank spaces)
Is there a better way ?
4) I'm trying to port the following TeX code to ConTeXt
$$\eqalign{x=1\cr y=2\cr}\qquad \hbox{haha}$$
it looks like \startformula\startalign.. doesn't allow me to do that
I somehow managed to have it by typing
\startformula
\vcenter{\starttabular[|rM|lM|]
\NC x \NC =1\NC\NR
\NC y \NC =2\NC\NR
\stoptabular}\qquad\text{haha}
\stopformula
the pdf export is fine, but the xml export is awfull (because of
\vcenter I guess)
a) Is there a way to use tables inside math mode alongside other stuff
(would be handy) ?
b) what is the correct way to type the previous text, so the pdf and xml
are fine in Context ?
Best regards
Olivier... really enjoying utf, xml, lua inside TeX as well as other
nice ConTeXt features

Re: [NTG-context] Testing the changing dimensions of boxes (in cycles) via Lua
Thanks very much to Luigi.
Your solution really works.
Can you please explain why you doing this? My point is that if I have
the LUA code in a separate lua file (loaded with the Contex via
\directlua{dofile(filename.lua)}) (for example as a separate Lua
function), so I'm probably not so to do (how you did it in your example).
Or perhaps in this case there is any way?

Re: [NTG-context] indexing puzzle
Michael—
Thank you so much for your very helpful response.
1. \unskip works well.
2. What I currently have is admittedly an ad hoc system for encoding my
indices. As you note, the system works for page numbers 99 where line
numbers 99. When line numbers 99, I adapt the sort key differently:
thus, for Cleomedes, *Cael*. I have [CleomCael105001] for 1.5.1. This works
(in MKII) but only because the number of entries is very small.
3. I like your MKII solution—it is much more general, works well on what I
have, and is certainly less taxing to encode. Many thanks!
The book that I trying to index right now is the last of my MKII projects.
So I am also interested in, and very grateful, for your MKIV solution.
All best, Alan

1. For \ab you might want
\def\ab{\unskip}
since the space is not the same as the width of a digit.
2. Does your solution work with line numbers greater than 99? I tried
to implement your idea and I got the order 25.7, 25.117, 25.37. Probably
more than 99 lines never occurs on a page, so it's a non-issue. But Homer,
for instance, is often referred to by Book.Line, and the lines go past 100.
Again, perhaps a non-issue for you.
3. My own attempts: At first I though what a nice opportunity for me
to learn a little more Lua, which it was. After, I read you wanted a MKII
solution. Well, I'm embarrassed at how long I took to do the MKII, but I'm
not good at controlling expansion. Anyway, it automatically generates sort
keys for the pages by converting digits to letters and padding with initial
a's, so that each page or line number is a fixed length (4 in this case, up
to 1 pages/lines). For instance,
123.4--56 is mapped to abcdaaaeaafg
MKII does not seem to sort digit-based keys reliably; MKIV does, and you
can just pad out the digits with zeros. The complete sort key that worked
was the catenation of the author, text, and locus key, which is similar to
what you have.
MKII:
\defineregister[Passage][Passages]
...
% interface to register -- \locuskey indirectly returns a key in \nextkey
\def\MyPassage#1#2#3{\locuskey{#3}\expandoneargafter\doMyPassage{\nextkey}{#1}{#2}{#3}}
\def\doMyPassage#1#2#3#4{\Passage[#2#3#1]{{#2}+{#3}+{#4}}}
% Def. of \locuskey#1
%In: #1-p1[.l2[--l3]] Out: key stored in \nextkey
... (see attached file, if interested)
MKIV:
% interface to register -- expansion in MKIV must be different, because
a direct approach works:
\def\MyPassage#1#2#3{\Passage[#1#2\locuskey{#3}]{#1+#2+#3}}
% Def. of \locuskey
\startluacode
userdata = userdata or { }
function userdata.locuskey(x)
context(string.gsub(x,(%d+),function (s) return
string.format(%04d,tonumber(s)) end))
end
\stopluacode
\def\locuskey#1{\ctxlua{userdata.locuskey(#1)}}
The Mark IV/Luatex one was much nicer, less frustrating to figure out.
On May 24, 2012, at 7:06 AM, Alan Bowen wrote:
For anyone interested in producing classical indices locorum, I have
devised a way that seems to work, although it is not that elegant.
The first step is to modify the sort keys by counting the number of
digits in the page number:
thus,
[AuthorText01] for pages 1–9,
[AuthorText02] for pages 10–99, and so on
The next is to insert the command “ \ab” (note the space) when the line
number is a single digit:
thus
391. \ab{}2 but 391.12 in the entry specification {Author+Text+page.line}
For \ab, I have:
\newdimen\digitwidth
\setbox0=\hbox{\tfx\char32}
\digitwidth=\wd0
\def\ab{\tfx\kern-\digitwidth}
The hitch here is that the font size is not context dependent.

I have been trying to index the passages cited in a book and would be
grateful for some tactical advice.
There are several works by a single author, and it is customary to cite
each text by page and line number, as in 1253.12 (page 1253, line12), for
example.
I have a sort key for each work. But now I need a way to get the entry
1253.7 (page 1253, line 7) before the entry
1253.12 (page 1253, line 12).
\[Passage[AuthorText]{Author+Text+1253.07}1253.7 or
\[Passage[AuthorText]{Author+Text+1253.07}1253. 7
would work, but it is really better to have the index entry as “1253.7”
rather than as “1253.07” or “1253. 7”
I have experimented with different sort keys—e.g., AuthorText125307—and
can generate an index with the 1235.7 and so on in the proper place and
form, say, before 1253.12.
But then the problem is that I also get entire sequences of entries out
of order (485.19, 485.21 before 477.31, and so on). Very puzzling.
(Restoring the sort key AuthorText removes the latter problems but then
leaves 1253.7 in the wrong place.)
If anyone has experience with this or just some ideas for a solution,
their suggestions will be most welcome.
I am using the MKII in the latest ConTeXt
Re: [NTG-context] indexing puzzle
Thanks, Alan. Actually, I now think MKIV works without any trickery. I was
perhaps too eager to try a Lua solution. \Passage{Author+Text+Locus} seems to
work fine in the beta today.

Michael—
Thank you so much for your very helpful response.
1. \unskip works well.
2. What I currently have is admittedly an ad hoc system for encoding my
indices. As you note, the system works for page numbers 99 where line
numbers 99. When line numbers 99, I adapt the sort key differently:
thus, for Cleomedes, *Cael*. I have [CleomCael105001] for 1.5.1. This
works (in MKII) but only because the number of entries is very small.
3. I like your MKII solution—it is much more general, works well on what
I have, and is certainly less taxing to encode. Many thanks!
The book that I trying to index right now is the last of my MKII
projects. So I am also interested in, and very grateful, for your MKIV
solution.
All best, Alan

not good at controlling expansion. Anyway, it automatically generates sort
keys for the pages by converting digits to letters and padding with initial
a's, so that each page or line number is a fixed length (4 in this case, up
to 1 pages/lines). For instance,
123.4--56 is mapped to abcdaaaeaafg
MKII does not seem to sort digit-based keys reliably; MKIV does, and you
can just pad out the digits with zeros. The complete sort key that worked
was the catenation of the author, text, and locus key, which is similar to
what you have.

Re: [NTG-context] Problem calling system
probably some os.execute parsing ...
Do you mean Lua itself does the parsing and substitution? I guessed [lua]tex
core...
When I try to call on the command line:
C:\Lukas\ConTeXt\TestDDvlua
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio
os.execute([[lua -e print 'WWW']])
WWW
os.execute([[echo lua -e print 'WWW']])
lua -e print 'WWW'
=os.exec
nil
=os.spawn
nil
- There is no '/ substitution in standalone Lua (?!).
does os.exec or os.spawn work ok?
Well, the 'os.exec' works, in condition that it is called with cmd /c:
\ctxlua{os.execute([[echo lua -e print 'EXECUTE']])}
\ctxlua{os.exec([[cmd.exe /c echo lua -e print 'EXEC']])}
\ctxlua{os.spawn([[cmd.exe /c echo lua -e print 'SPAWN']])}
\starttext
A
\stoptext
Gives:
...
languageslanguage en is active
lua -e print EXECUTE
lua -e print 'EXEC'
system | total runtime: 0.609
Interesting that the string to be passed to 'os.exec' keeps ' whilst that to
'os.execute' doesn't.
Why this happens?
Anyhow, thanks for the idea with 'os.exec'.
Best regards,
Lukas

Please create a complete working minimal example.

[NTG-context] Split \startalign content on more pages
Sorry for having given you a non working example!
Here you can find a working one. The comments at the end of each line are in
italian.
Changing the height of the frame you can move the \startalign content in the
page.
As you will see, the whole content flows from one page to the following,
without splitting at the right line.
Thank you very much for your help.

A better alternative would to define

that can be used to set the style for metapost text.
this is ok for me, but then we mighe as well drop \startMPenviroment

[NTG-context] Wiki - results differ?
Hello,
Wiki and a file processed on a local computer give different results -
- please compare http://wiki.contextgarden.net/Command/doif...;
and the example attached:
\starttext
\ctxlua{test = true}
Test is \ctxlua{commands.testcase(test)}{True}{False}.
\ctxlua{test = false}
Test is \ctxlua{commands.testcase(test)}{True}{False}.
\stoptext
The result should be:
Test is True.
Test is False.
which works fine on my computer.
But wiki shows (wrongly):
Test is TrueFalse.
Test is TrueFalse.
although the same code is used in the example:
context source=yes text=Gives:
\starttext
\ctxlua{test = true}
Test is \ctxlua{commands.testcase(test)}{True}{False}.
\ctxlua{test = false}
Test is \ctxlua{commands.testcase(test)}{True}{False}.
\stoptext
/context
Any idea why both results differ?
And how to make wiki show the good result?
Best regards,
Lukas

[NTG-context] extracting word count from a *.words file
Hello all,
Here is another question. Consider this test file:
\starttext
\setupspellchecking[state=start,method=2]
\ctxlua{languages.words.threshold=3}
\input knuth
\stoptext
Typesetting this file produces a word list 'test.words' which ends like
this:
[threshold]=1,
[total]=122,
[version]=1,
}
Is there a way to extract the value for [total] ('122' in this case)
so that I can use that value somewhere else, e.g. in a project file
where I want to present a word count.
Thanks for a pointer!

The “.words”-file is well formed Lua code, so you can just
integrate it as a table:
\define\wordcount{%%% Displays word count.
This document consists of
\startluacode
local data = dofile\jobname.words %% Load data of _previous_ pass
context(data.total) %% access the requested field
\stopluacode
\space
words.%
}
\starttext
\setupspellchecking[state=start,method=2]
\ctxlua{languages.words.threshold=3}
\input knuth
\hairline
\wordcount %% call to the macro
\stoptext
Thanks for a pointer!
Thanks as well, btw, I didn’t know the word count facility yet!

I used the word count some time ago. Here's the code I used. I have
no idea what has changed since and if it still works.
\startluacode

local w = dofile(filename)

if type(w.categories[listname]) == table then
context(w.categories[listname].total)
else
context(w.total)
end
context.par()
end
end
end

\def\wordcount{%
\dosingleempty\dowordcount}
\def\dowordcount[#1]{%
\ctxlua{userdata.wordcount(#1)}}

Hey list,
Is it possible to instruct ConTeXt to generate just the table of

outputted PDF:
% Contents at a glance...
\title{Contents at a Glance}
\placelist[chapter]
% Complete table of contents...
\title{Table of Contents}
\placecontent
Right now I am generating the full book, but then passing through pdftk
manually to extract just the pages that fall within the aforementioned.
I tried putting the aforementioned code in its own product file and then
passing that through ConTeXt with the book's environment, but the
problem is that the TOC now has nothing in it, of course.
I don't know if there is proper interface to this, but you can just load
the tuc file and reuse the labels.

Re: [NTG-context] Hooking \stoptext
... OK, your solution works -
- But I'd need one which doesn't force user to hook manually; i.e. without:
\let\Oldstoptext\stoptext
\def\stoptext{%
\startluacode
context(END)
\stopluacode
\Oldstoptext
}
Hooking should be performed in a Lua function and should be invisible to the
user.
More complicated example:
t-Hook4.mkiv
\startluacode
function foo()
local stoptext_p = context.stoptext
context.stoptext = function(...)
context(END)
stoptext_p(...)
end
end
\stopluacode
\starttext
\input knuth
\ctxlua{foo()} % This should cause END to appear at the end of the document
\stoptext
In this case, foo() is a function which does the hooking; and foo() may be placed in
another file or Lua toolbox, so user is to call Lua's require 'my-Lua-toolbox-with-foo' foo().
So user is not forced to know how the function works; once he uses it, the text
END will appear at the end of the document.
- And this doesn't happen to me; and my goal is to make it work.

It doesn't bail unless I replace the previous definition with yours.
Here is an example of its usage from my source:
\setupinteraction

Why don't you use the first version (\initializebazaarversion and

\def\initializeBazaar

\initializeBazaar

\starttext
Hello \BazaarRevision Bye
\stoptext
The rest of the book just has some \BazaarRevision scattered here and
there, but I can't see anything unusual about their usage or context.
It helps if you try to create a minimal example.

The cleaner way is to seperate the setup and use. For example:
\def\initilizebazaar
{\ctxlua{context.setevalue(
usebazaarrevision,
os.resultofbzr revno | tr -d '\\n')}}
\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 to

[NTG-context] Problem with Lua processing UTF8 substrings
Hello ConTeXist,
I want to use Lua to write characters (substrings) from a string, but I

I tried various Lua functions for working with UTF8 strings for example:

string.lenutf8(string),
but without success.
Can you please someone help?

Have you tried the unicode library? The standard string library
operates on bytes, therefore extracting a single byte yields an
incomplete multibyte char if the codepoint is beyond ascii.

(Lazy people would just do a “local string = unicode.utf8” at the

[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

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] 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

Re: [NTG-context] How to define a command...
Reccently I did something random in ctxlua. I post it in the hope it will be
useful.
Hans van der Meer
\startluacode
-- Define our namespace as hvdm
hvdm = hvdm or {}
-- Return random series of numbers 1..n depending on the number of
arguments
function hvdm.randomseries (n, straight)
local done = {}
for i = 1, n do
done[i] = i
end
if straight == false then
return table.concat(done,,)
end
local result =
for i = n, 2, -1 do
local r = math.random(i)
result = result .. done[r] .. ,
table.remove(done,r)
end
result = result .. done[1]
return result
end
\stopluacode
\def\RandomSeed#1{\directlua{math.randomseed(#1)}}
