[NTG-context] Re: documentation: parameters of \setuplist

[Duncan Hothersall]

Hi Hraban,

I can help with one - aligntitle means an unnumbered section will align in
the table of contents under the number rather than the title. So for
example if you have a TOC combining \section and \subject entries, they
would look like this:

1 ... A section
A subject

rather than

1 ... A section
.. A subject

Re: [NTG-context] Xml filtering in Lua

[Duncan Hothersall via ntg-context]

Hi Thomas.

I'm not sure about the code, sorry, but I do know that an XML document
can't have two IDs of the same value. Typically you would use a linkend
attribute on the element which is referencing an id (in this case the
topics, I think).

Probably doesn't help with your problem, but it's likely a prerequisite for
it to work.

Bests,

Duncan

Re: [NTG-context] overprinting black

[Duncan Hothersall via ntg-context]

Have you tried overprint=yes? I have that in old files which used to work
under mkii. I must admit I haven't had the need to use overprinting since
then, but I do recall that come colour handling wasn't ported across to
mkiv or later.

Re: [NTG-context] MathML when processing XML

[Duncan Hothersall via ntg-context]

Answering my own question - the rules in x-mathml.mkxl/.lmt assume *only*
an mml: namespace on MathML elements. Having built my current project on
the basis of the examples in the XML in mkiv manual, I had two layers of
namespaces in addition to that. Redoing the mappings for the MathML
elements resulted in glorious formulas coming out.

[NTG-context] MathML when processing XML

[Duncan Hothersall via ntg-context]

This feels like a really stupid question but I can't find an answer to it
anywhere.

When processing an XML file directly with ConTeXt, i.e.
using \startxmlsetups rules, how can I make use of the MathML module for
the MathML content in my XML source? Should I include a specific piece of
code with a \registerctxluafile command as well as / instead of
\usemodule[mathml]? Do I need to use something other than \xmlflush to pass
the XML to the module?

Sorry, it's probably obvious but I can't work it out!

Thanks.

Re: [NTG-context] XML: calculations on attribute values before output

[Duncan Hothersall via ntg-context]

Thanks so much Taco, that opens the door to a lot for me. It's a tricky
learning curve.

Just in case anyone else is copying code in future for CALS, there's a tiny
tweak to the rows calculation, it should be (t.at.morerows or 0) + 1.

I see a route to solving lots of other problems here too. Thanks again.

[NTG-context] XML: calculations on attribute values before output

[Duncan Hothersall via ntg-context]

Hi.

I'm processing an XML table and need to set a row span. Because we use a
variant of the CALS table model, spans are defined by an attribute saying
how many *additional* rows should be spanned, as opposed to how many *in
total*. So to translate this into TABLE \bTD[nr=X] syntax I need to add 1.

I'm guessing this is very easily doable (in lua?) but I've tried various
permutations and can't work it out. If anyone could give me a pointer that
would be great.

(In reality I'm going to need to handle lots of other conversions of
attribute values into \bTD[...] commands, so if there's a generalised way
of doing that sort of thing, or even better if someone has already tackled
CALS tables in this way, that would also be great!)

MWE below, but obviously it just passes the morerows="1" value straight
through into \bTD[nr=1] so it doesn't give me a row span at all.

Thanks in advance.

Re: [NTG-context] XML processing instructions

[Duncan Hothersall via ntg-context]

Just following up on my own question in case anybody else is interested, I
realised that the logic of my preprocessor code wasn't the problem, it was
just my ignorance of lua and character escaping. Both ? and * are special
characters in string.gsub expressions, so they need to be escaped with the
lua escape character which is % (which sends my editor haywire because it
thinks I am putting in a TeX comment, but never mind!).

So my now working code to translate historic processing instructions into
directives without a separate pass is:

\startluacode
function lxml.preprocessor(data)
 data = string.gsub(data, '<%?capdm %*force_line_stop%?>',
'')
 return data
end
\stopluacode

\startsetups xml:directive:injector:newline
 \crlf
\stopsetups

Re: [NTG-context] XML processing instructions

[Duncan Hothersall via ntg-context]

Many thanks Denis. Very useful tip on the injectors and generalised command
usage. That will definitely come in useful.

My problem is that I already have a lot of XML data with the existing
processing instructions in it. I know I could use an external preprocess in
something like Python to change them into injectors before they are fed
into ConTeXt, but I was hoping there was a way to handle them directly as
part of the ConTeXt / lua process.

Thanks again though.

Re: [NTG-context] XML processing instructions

[Duncan Hothersall via ntg-context]

Apologies, there are two rogue * in the lxml.preprocessor code, but even
when they are removed it doesn't work.

[NTG-context] XML processing instructions

[Duncan Hothersall via ntg-context]

I have a big set of existing XML books (held in a derivative of DocBook)
which I'm looking to start processing directly with ConTeXt. (Up to now I
have a system which converts the XML into ConTeXt code which is then
processed, but this is inefficient and lots of the code is now unsupported.)

I've had some success producing output, but my first real sticking point
has come with processing instructions. The existing XML contains lots of
processing instructions of the form
, some of which can be conditional and introduce new data
etc. But I'd be happy at this stage if I could just process the most basic
one of them, which is used to introduce a line stop in a running paragraph
of text.

My best guess at how to do this was to use the lxml.preprocessor function
to convert the processing instruction into an element, and then process the
element as normal. But (a) my attempt didn't work, and (b) there may well
be a better way.

Minimal working example below, except that obviously the processing
instruction bit doesn't work!

Thanks for any help or insights.

Duncan

Re: [NTG-context] Space around figure

[Duncan Hothersall via ntg-context]

You should be able to change the space above and below a float with the
spacebefore and spaceafter keys to \setupfloat. I think the default value
is big for each, but you can override that with null. Something like

\setupfloat[figure][spacebefore=,spaceafter=]

Hope that helps.

Re: [NTG-context] How to group list of figures and list of tables by chapter?

You could try using \writebetweenlist hooked into \setuphead[chapter]?
Something like (untested):

\setuphead[chapter][before={\writebetweenlist[figure][location=here]{\blank}}]

(Sorry, can't currently test this.)

Worth just quickly noting that the default for \part is placehead=no. You
need to explicitly set placehead=yes for it to actually output the heading.

Re: [NTG-context] mathcolor attribute in MathML (mkiv)

[Duncan Hothersall]

Understood and appreciated, Hans, and many thanks for the patch which I
will be testing shortly.

Completely agree re the real world of MathML. We are still converting our
MathML masters to other formats after many years for various uses and fixes
because of the situation you describe with patchy and dodgy support
especially in the browser world. Maths on the web is still a little bit
wild west.

Thanks again.

Duncan

[NTG-context] mathcolor attribute in MathML (mkiv)

[Duncan Hothersall]

Hello list.

I'm trying to use colour in some MathML formulae using the mathcolor
attribute. It seems to have no effect on the output. I can
see \applymmlmathcolor in the x-mathml.mkiv source but I can't see how to
make it work. Does anyone have any pointers?

(Does lmtx support this?)

Thanks.

I'd like to second Denis' request for support for XML processing
instructions to execute ConTeXt code, rather than elements which can cause
big problems if one is working to a fixed schema. It would be a boon to be

I don't think \showinjector needs an argument. My MWE when I was looking at
this has just \showinjector after the register definition but before the
\setinjector[...] commands.

Re: [NTG-context] Fine tuning an index

[Duncan Hothersall]

Just a note to add, that \showinjector doesn't seem to do anything unless
you also have a \setinjector command, which is a bit counterintuitive since
probably the first thing you want to do is see the ID of each line in your
list/register before you know what \setinjector command you need.

I've worked around it by adding

\setinjector[register][1][\relax]

after \showinjector.

[NTG-context] Fine tuning an index

[Duncan Hothersall]

I'm doing my first mkiv index (it took me a long time to upgrade from
mkii!) and I really like the processor feature to format elements
differently. But there are a couple of things I would really like to
achieve that I'm struggling with:

   1. Elided numbers in an index range entry. For example if I have a
   \startregister - \stopregister pair resulting in an index entry like

   entry 354--356

   I would like to be able to make this read

   entry 354--6

   There are different conventions for number span elision but usually
   teens aren't elided so

   entry 314--316

   would become

   entry 314-16.

   It strikes me that if I could set up a processor specifically for page
   number ranges I could possibly write a macro to do elision; but I don't
   think that's currently possible? Maybe it's possible in lua to write code
   which both identifies range page numbers and carries out the elision. I'm
   not quite sure where to start.

   2. Fine tuning column and page breaking in an index. This is tricky,
   because there are usually very few "good" places to break an index, and
   automatic breaking seems to alter slightly depending on whether
   interactions are set up or not, but is there a way to manually insert a
   column or page break into the register before or after a certain entry, the
   way there is for a table of contents?

Sorry for no MWE, for obvious reasons. Any pointers to what might be able
to be done on these would be much appreciated.

Thanks.

[NTG-context] Index range with page number suffix

[Duncan Hothersall]

(Using mkiv.)

I have an index in which some entries need suffixes on the page numbers,
for which I have used processors.

For index ranges, I need the page number suffix only to appear on the end
page number, not the start page number.

The below MWE produces an index entry: sausage  1i-2i

What I need is: sausage  1-2i

Is this possible?

MWE

\defineprocessor[important][right={\it{i}}]

\starttext
\samplefile{knuth}
\startregister[index][sausage][important->sausage]{sausage}
\dorecurse{6}{\samplefile{knuth}}
\stopregister[index][sausage]{sausage}
\samplefile{knuth}
\page
\placeindex
\stoptext


Thanks in advance,

Re: [NTG-context] Overriding the number on a float

[Duncan Hothersall]

Thanks all for useful tips. I ended up doing something similar as a short
term fix for my float number override issue, basically setting up a new
float type to use for the deviant ones and then resetting the numbering of
the existing ones. It would be great if there was a facility to just drop
in an override on an individual float using the equivalent of
ownnumber={27.1b}, but I appreciate this may be much more complex under the
hood than it seems to a mere mortal. Certainly my brief perusal of the
sources left me baffled, as usual!

Thanks again.

[NTG-context] Overriding the number on a float

[Duncan Hothersall]

I think there was a question on this very recently but I don;t think it got
an answer and I can't find it to reply to, so apologies for the extra
noise. I have a large text with floats numbered sequentially by chapter and
then figure/table number, but at the last minute I've had a request for two
figures in a particular chapter to become 27.1a and 27.1b instead of 27.1
and 27.2. It's not a combination - they are separate figures on different
pages.

I've experimented with the options I can see, but it's not obvious if there
is a facility to override the numbering of two figures in a stream of
normally numbered figures like this. I was thinking of the equivalent of
the old \sym{symbol} command that used to work as a way to override a
single item in an otherwise sequential list.

I guess there's a brute force method of setting up a new type of figure
with the label "Figure 27.1" and having them numbered as lowercase alpha,
but if there's an easier way that would be great.

Thanks.

Re: [NTG-context] chapter numbers

[Duncan Hothersall]

Use \setuplabeltext instead of \setupheadtext. I agree the documentation
suggests \setupheadtext should work the same way, but it doesn't seem to.
You might also want a space after the word Chapter.

[NTG-context] MathML (mkiv) accent shifted to the left

[Duncan Hothersall]

Hi all.

I am reasonably sure that in mkii this overbar accent was placed correctly,
but in mkiv it is shifted to the left. Any ideas on how to fix it?

MWE:

\usemodule[mathml]
\starttext
This \xmlprocessdata{}{p}{} isn't
right.
\stoptext

Many thanks,

Duncan

Re: [NTG-context] Strange pagebreaks in LMTX

I have found in similar situations sometimes the easiest fix is to set the

[NTG-context] Override MathML formula label

[Duncan Hothersall]

Hi all.

In processing MathML if I want a formula to be numbered I add a label="X"
attribute to the  tag as per:

\usemodule[mathml]
\starttext
\xmlprocessdata{}{
 
  p=c-t
 
}{}
\stoptext

This will label the formula as (1). I know I can adjust how the automatic
numbering is generated using \setupformulae, but how can I override the
label used for a specific formula, say to set it to (36A)?

Basically I have a setup where formulae are mostly numbered sequentially
but occasionally individual formulae need to have an out-of-sequence or
differently formatted number.

Thanks as ever for any help.

[NTG-context] Unwanted white box above float

[Duncan Hothersall]

Hi all.

Have been experimenting with the many and varied options for placefloat to
try to resolve this problem with no success. As per minimal example below I
have nearly what I'm after - an image which floats to the right of a
background box with a 1em offset - but I can't get rid of the white box
which appears above it no matter what permutations I try.

(Secondary query: why do I have to set leftoffset=, rightoffset= etc.
individually for the text background? offset= seems to have no effect.)

Thanks for any help you can offer.


\definetextbackground[TintBoxedBackground]
[background=color,
backgroundcolor=cyan,
frame=off,
leftoffset=1em,
rightoffset=1em,
topoffset=1em,
bottomoffset=1em,
location=paragraph]

\definefloat[thematicimage][figure]
\setupfloat[thematicimage]
[default=right,none},
offset=1em,
margin=0em,
background=color,
backgroundcolor=cyan,
rightmargindistance=-1em]

Very many thanks Henri for your patient explanation, and my apologies for
inadvertently asking a FAQ. I had thought the effect hasn't happened with
the same content in mkii but it must have been a happenstance of different
formatting.

Thanks again for the clear solution.

[NTG-context] Side figure bug in mkiv?

[Duncan Hothersall]

I think I have identified a bug in the side figure mechanism which is
demonstrated by the minimal example below. The {\bf …} construct causes the
para in which it appears to stop behaving properly with the side figure,
and the text overflows. The preceding and following paras which don't have
{\bf …} do behave properly.

I wondered if emphasis like \bf should be done differently (with a
start/stop mechanism?) in mkiv, but I found nothing to suggest it.

\starttext
Blah blah.
\placefigure[right,none]{}{\externalfigure[cow][width=0.30\makeupwidth]}

[NTG-context] From mkii to mkiv: MathML mtable alignment

[Duncan Hothersall]

The command \setupMMLappearance[mtable][alternative=b] used to give me, in
mkii, MathML layouts in which the first column was ragged left, the second
column centred, and the third column ragged right. It now seems to be
ignored, and the output has all three columns centred.

Minimal working example showing the problem:

\usemodule[mathml]

\setupMMLappearance[mtable][alternative=c]

\starttext

Some text.

\xmlprocessdata{}{

 
  
   
x

y

 million
   
  
  
   
x

2.56
   
  
 

  }{}

Some more text.

What is the successor to \setupMMLappearance please?

Thanks very much.

[NTG-context] mkiv MathML bug?

[Duncan Hothersall]

I'm not sure this is something more general in the MathML module or if it's
specific to the vertical bar in this particular context, but here is a
minimal example showing that the "=0" at the end of the equation is
disappearing:

\usemodule[mathml]
\starttext
\xmlprocessdata{}{

  A
  
B
|
C
  
  =
  0

  }{}
\stoptext

And here is a workaround using  instead of  for the vertical bar
which makes the "=0" magically reappear again:

\usemodule[mathml]
\starttext
\xmlprocessdata{}{

  A
  
B
|
C
  
  =
  0

  }{}
\stoptext

Flagged up mainly in case it is a bigger problem than just vertical bars in
this specific context.

Thanks,

Thanks Hans. After some searching in the test suite I found the answer,
which I'll put here in case someone else is searching for it, which is:

\setuphead[section][sectionsegments=section]
\setuphead[subsection][sectionsegments=section:subsection]

which sets up sections to just be numbered with the section number instead
of the part, chapter and section number, and sets up subsections to just be
numbered with the section and subsection number.

Now that I know how to do it I see mkiv is much cleaner on this code and
the change gets reflected in tables of contents etc. This was much harder
in mkii. Thanks again.

[NTG-context] mkii to mkiv - section numbering with minimal example

[Duncan Hothersall]

Further to my previous query about updating from mkii to mkiv, I have
solved some of the issues by trial and error but am beginning to identify
the ones I can't resolve. My first minimal example is below.

I want the sections and subsections not to prefix the part and chapter
numbering, giving me this output:

Part 1
Chapter 1.1
Section 1
Subsection 1.1

The line that used to achieve this result was

\setupsection[section-3][previousnumber=no]

and there was also

\setuphead[section][partnumber=no,chapternumber=no]

but neither of these seems to work in mkiv


Minimal example:

\setupsection[section-3][previousnumber=no]
\setuphead[section][partnumber=no,chapternumber=no]

\starttext
\part{Part}
Part
\chapter{Chapter}
Chapter
\section{Section}
Section
\subsection{Subsection}
Subsection
\stoptext

Many thanks for any pointers.

Re: [NTG-context] mkii to mkiv - what an ancient user needs to know

[Duncan Hothersall]

Thanks Hans, that's good to know. I was seeing issues which seemed to be
related to setupheader statements using command=, which are in heavy use in
our system because we use this to externalise styles. But it could easily
have been something font-related left in some of the commands.

I will work on a minimal example over the next few days and - if I don't
solve it myself in the process - I'll post it.

Thanks again,

[NTG-context] mkii to mkiv - what an ancient user needs to know

[Duncan Hothersall]

Hi all.

Long-time user but haven't posted in a long while...

After many happy years of running a mkii set up I am finally facing the
fact that time has moved on and upgrading to mkiv.

I understand the biggest change needed to my sources is in the fonts
handling, but I am getting a few other problems with things like
chapter/sectioning setups that I can't see mentioned in
https://www.contextgarden.net/MkIV_Differences

I was wondering if there exists a comprehensive "what you have to change in
your sources to move from mkii to mkiv" document anywhere or, failing that,
if anyone can offer guidance on what has changed in the chapter/sectioning
setups code between the two.

Apologies for not supplying an example of code - I'm not yet at the point
that that's possible.

Any help much appreciated. And hello to anyone who remembers me from
fifteen plus years ago!

[NTG-context] MP spot color in gradient - help!

[Duncan Hothersall]

 Struggling against a deadline here so apologies for no full sample.

I have a gradient fill defined using


\startuseMPgraphic{mpos:par:mylearnobj}
path p;
for i = 1 upto nofmultipars :
p := multipars[1] topenlarged 8pt bottomenlarged 8pt leftenlarged 3cm ;
color ca ; ca := \MPcolor{greenthirty} ;
color cb ; cb := \MPcolor{white} ;
sh := define_linear_shade(origin, origin shifted (120mm,0), ca, cb) ;
fill p withshade sh ;
endfor;
\stopuseMPgraphic


This works if the colour greenthirty is defined as a CMYK colour

\definecolor[TAXBgreenthirty][c=.3,m=0,y=.057,k=.069]

but, inevitably, my printer wants it defined as a spot ink, and when I 
do this:


\definecolor[PantoneThreeOneFourFive][c=1,m=0,y=.19,k=.23]
\definespotcolor[TAXBgreenthirty][PantoneThreeOneFourFive][p=.3]

the gradient turns to black instead of green. (The spot colour 
definition works fine in the rest of the document, just not in the 
gradient fill.)


Could someone possibly let me know if it is even possible to define a 
gradient using a spot colour, or if I should instead revert to some 
alternative solution.


Thanks,

Duncan

Re: [NTG-context] MP spot color in gradient - help!

[Duncan Hothersall]

 Right, thanks very much for the quick response Hans. I can remap 
colours with the tools we have here, except in the case of a gradient 
fill. I think I will try using a repeated graphic as a background 
instead, while waiting for printer's thoughts.


Thanks,

Duncan

I don't think so. Normally, if you use a specific color (recognizable) 
the printer should be able to remap that to some spot color (at least 
that is what we have done in the past, cf publisher specs).

not sure what you expect ... you have no hyperlinks (annotations) .. 
where do you expect to see destinations in pro? 
You can view a list of all named destinations in a file in Pro (View; 
Navigation tabs; Destinations) and these are externally accessible via 
links of the form filename.pdf#nameddest=destination name. That's what 
I'm trying to achieve.


It looks like it might be achievable with a third-party module called 
Navigator documented here:

I haven't tried that out yet.

[NTG-context] Creating a PDF named destination

[Duncan Hothersall]

 Hello all,

This seems to be a very obvious FAQ but I can't find an answer anywhere. 
How can one create a named destination in an output PDF file such that 
an HTML link to filename.pdf#nameddest=name will work?


I'm using Mk II in case that is relevant. I kinda assumed that a section 
title with an ID would automatically create a named destination with the 
same ID, but that doesn't appear to be the case.


So given a file generated from


\starttext
\chapter[myid]{My chapter}
Blah blah.
\section[myotherid]{My section}
Blah blah.
\stoptext


I'd like to be able to link from an HTML file to the named destinations 
myid and myotherid using the #nameddest URL construct above.


Hope it makes sense and thanks for any help.

[NTG-context] Dotted leader in index entries

[Duncan Hothersall]

[Now with a proper example!]

Hello all.

I'm using Mk II. I need to set up dotted leaders between an index entry 
and its page number as show in this runnable sample:


\def\Icmd#1{#1\dotfill}
\setupregister[index][n=2,textcommand=\Icmd,distance=1em,alternative=A]
\starttext
\index{Example+This index entry doesn't quite work}\index{This is 
okay}\index{Example+This is okay}\index{This index entry is not correct 
at all}\index{Example+This is another example in which the leaders don't 
work cos of wrapping}A little text.\par

\placeindex
\stoptext

When the entry text is just long enough to fill up the horizontal space 
it is pushing the number over onto the next line. What I really need is 
for all page numbers to be at the right hand side, with leading dots. So 
I'd like a solution to produce either this:


Long index entry text
  123

or this:

Long index entry
  text..123

At the moment I'm putting forced line breaks before the last word to 
achieve what I need, but I would really like to automate this!


Thanks for any help, hope the issue is clear.

 [Reposting because I think my last message got mangled.]

Hello all.

I'm using Mk II. When I use the following setup to get dotted leaders 
between an index entry and its page number:


\def\MyIndexTextCmd#1{#1\dotfill}
\setupregister[Index][n=2,textcommand=\MyIndexTextCmd,distance=1em,alternative=A]

it works okay producing output like this:

Index entry.123

except when the entry text is just long enough to fill up the horizontal 
space, pushing the number over onto the next line. What I get in that 
scenario is this:


Index entry text...
  123

This is no good. What I really need is for all page numbers to be at the 
right hand side, with leading dots. So I'd like a solution to produce 
either this:


Index entry text...

[NTG-context] Dotted leader in index entries

Hello all.

[Using Mk II.]

I need to produce an index which looks like this:

Mainentry
   Subentry.3
   Slightly longer
   subentry..5
   See also X

I have the following setup:

\def\MyIndexTextCmd#1{#1\dotfill}
\setupregister[Index][n=2,textcommand=\MyIndexTextCmd,distance=1em,alternative=A]

which gives me something like:

Mainentry
   Subentry.3
   Slightly longer subentry..

   5
   See also X

I can work around the problem of the "See also X" line by adding an
\hfilll to avoid the generation of dots. But I really need all
pagenumbers to be at the right hand side, and not allow them to
break over to the left like in the second example.

At the moment I'm putting forced line breaks before the last word to
achieve what I need, but I would really like to automate this!

Thanks for any help, hope the issue is clear.

[NTG-context] Forcing \about to give the full title

[Duncan Hothersall]

 Hi folks.

Just hit a strange feature using \about to give me the title of a 
referenced section. When the title is long, there seems to be an 
automatic cut-off, as if some form of \nomarking had been used on the 
last words of the title. So with a section somewhere in the text like


\section[sect0101]{Residence and domicile and the taxation of overseas 
income}


a later reference of the form

See \about[sect0101] for further details

gives me

See 'Residence and domicile and the taxation of overseas ... ' for 
further details



What I would like is for the full title to be output, however long. I 
have had a look through the sources but not managed to identify where 
any default cut-off is defined. Can someone help.


Oh, and my apologies, I haven't upgraded to MkIV yet, so this is a MkII 
question.


Thanks very much,

Duncan

[NTG-context] MPgraphic with rounded corners

[Duncan Hothersall]

Hello all.

I have adapted a bit of MP code from Aditya from a mailing list message 
dated 2006-05-19 
(http://archive.contextgarden.net/message/20060519.214124.9174ac0e.en.html) 
to ensure that when a page break occurs in a textbackground there is a 
forced vertical space inside the box at the top of the new page.


This code works fine for me (although interestingly not in the garden):


\setupcolors[state=start]

\startuseMPgraphic{mpos:par:myexample}
path p;
for i = 1 upto nofmultipars :
p := multipars[1] topenlarged 8pt bottomenlarged 8pt;
fill p withcolor 0.9white ;
draw p withcolor black
withpen pencircle scaled \MPvar{linewidth};
endfor;
\stopuseMPgraphic

\definetextbackground[ExampleBackground]
   
[mp=mpos:par:myexample,location=paragraph,leftoffset=1em,rightoffset=1em,rulethickness=1pt]


\starttext
\input knuth \endgraf
\starttextbackground[ExampleBackground]
\dorecurse{13}{\input knuth \endgraf}
\stoptextbackground
\input knuth \endgraf
\stoptext


But now I need to make this box have rounded corners, and I am very 
confused when reading core-pgr.tex because that is a level of MP code I 
just don't understand.


Would somebody please be able to tell me what to change in the above to 
make the corners of the box rounded (with a radius of 2mm)?


Thank you very much!

[NTG-context] setupMMLappearance

[Duncan Hothersall]

Hello.

I am used to using
\setupMMLappearance[mtable][alternative=a|b|c]
to change the way the mathml module treats mtable alignments. I've just 
discovered it no longer seems to have any effect.

What I need to set up is an alignment where the first column of an 
mtable is right-aligned (ragged left), the second is centred, and the 
third is left-aligned (ragged right). But I keep getting the first 
column left-aligned, which makes multi-line equations look awful.

Is there a new mechanism for setting these alignments? It looked like it 
from reading newmml, but there don't seem to be any examples of usage. 
Can someone help?

Secondary question: how can I increase the gap between rows in an mtable 
- at the moment they are very squashed.

Sample code follows - produces ugly output on the garden:

\usemodule[newmml]
\setupMMLappearance[mtable][alternative=b]

[NTG-context] Sections, cross-references and separators

[Duncan Hothersall]

Dear all,

I am confused. Here is a minimal version of my problem:

---
\setupheads[separator=] %-- this can't be right
\setupreferencing[state=start,chapternumber=yes,global=yes]
\setupsection[section-1][conversion=Characters]
\setupsection[section-2][previousnumber=yes]
\setuphead[part][placehead=yes,resetnumber=yes,page=no]
\setuphead[chapter][page=no]
\setuphead[section][number=no]
\setuppagenumbering[partnumber=no]
\starttext
\placelist[part,chapter,section][alternative=b,partnumber=no]
\part[ptest]{Ptest}
\chapter[ctest]{Ctest}
\section[stest]{Stest}
See \in{Chapter}[ctest] (should say A1) and \in{Figure}[ftest] (should 
say A1.1).
\placefigure[here][ftest]{Ftest (should be called A1.1)}{}
\stoptext
---

What I am aiming for is a style where:
Parts are labelled A, B, C [done],
Chapters are labelled A1, A2, A3 [done, but...],
Cross-references to Chapters call them A1, A2, A3 [not done: I'm 
getting A.1]
Figures are labelled A1.1, A1.2 [not done; I'm getting A.11 (eek!)]
Cross-references to Figures call them A1.1, A1.2 [not done: I'm 
getting A.11]

It seems to me that the line
\setupheads[separator=]
can't possibly be right and is almost certainly causing the missing dot 
in the Figure number, but it was the only way I could find to remove the 
dot between the A and the 1 in the chapter label. I have toiled a little 
with the core-ref code and cannot fathom how any of the variety of uses 
of the word separator make sense, or indeed if they really have 
anything to do with it... :-)

I'm testing on the garden, using pdfTeX. I'd be *really* grateful for 
some help with this one.

Thanks,

Duncan

[NTG-context] Font sizes using Chinese module

[Duncan Hothersall]

Hello all. I hope this is quite a simple question.

I'm using the Chinese module, with the font definitions in font-chi.tex, 
to typeset UTF-8 content. I can happily use the default sizes a, b, c, d 
and x, xx, xxx - so \bfd produces large bold, and \tfx produces small 
normal weight text.

But I really need to be able to do the equivalent of \definedfont[Bold 
at 48pt]. Unfortunately this doesn't work - it produces normal text size 
and weight.

Unfortunately it isn't easy to post an example, because you need UTF-8 
content, and you need the fonts set up for Chinese (which I believe 
ConTeXt Live doesn't currently have). So I'm hoping that someone 
familiar with the workings of font-chi.tex can tell me how to get 
specific point sizes of specific fonts. Is there a unicode font 
equivalent of \definedfont? Or a way of adding an e and f size 
definition to the default set?

Any help would be really appreciated, thanks.

Duncan

Ah, thanks. Using \setupbodyfontenvironment as the second command did 
the trick.

I guess there is no easy way of directly calling a specific font at a 
specific size? No worry, this sort of solution will allow me to do what 
I need for now. Thanks Hans.

 No, there is not (at least not using any of the 'stock' tex

Indeed not trivial. But something I played with once upon a time for 
much the same purpose. You should take a look at Jonathan Fine's TeX 
daemon project texd (http://sourceforge.net/projects/texd) if you 
haven't already - it runs as a pipe (unix) and only loads formats once; 
it would take a little bit work to get it going reliably with ConTeXt, 
especially to do so in a way that is easily updated when a new ConTeXt 
is released, and I'm not sure if Jonathan is still actively working on 
the project. But it demonstrates an effective approach, which works with 
Plain (and LaTeX I think).

Re: [NTG-context] currentheadnumber / doif.. problem

 Subject: [NTG-context] currentheadnumber / doif.. problem
 To: ntg-context@ntg.nl

 Hi,

 I tried to get the full present heading-number. If I am using currentnumber
 I am getting back only the last part of the heading-number. So I tried do
 implement a function like this:

 ...
I don't have much time to investigate properly but there should be a 
\complexheadnumber defined in core-sec which gives you what you need. 
This should be tied to \headnumber though, so if that doesn't work it 
may be to do with where or how you are using the command. Do you have a 
complete minimal example document?

[NTG-context] Different parameters for a continuing itemization

[Duncan Hothersall]

I use \startitemize[continue] quite a lot to create itemised lists which 
continue on from the last number of the previous list. I've only just 
noticed that the 'continue' keyword seems to mean that parameters in the 
second [...=...] list of a \startitemize are ignored.

Example (tested on live @ contextgarden):

\setupcolors[state=start]
\starttext
Hello world!
\startitemize[n][color=blue,stopper={jkl}]
\item Hello world!
\item Hello world!
\stopitemize
Hello world!
\startitemize[n,inmargin,continue][color=red,stopper={mnb}]
\item Hello world!
\item Hello world!
\stopitemize
\stoptext

Note that the inmargin keyword in the second \startitemize does seem to 
work, but the parameters in the second set of [...=...] are ignored.

I would really like to be able to continue numbering but be able to 
override formatting in the continuing list. I *thought* I had been able 
to do this before, but maybe not. If continue needs to keep this 
behaviour, is there any chance of a new continuenumberingonly keyword, 
or similar? :-)

(The real world example involves moving from numbering in columns to 
numbering in the margin, but I need to adjust the width parameter for 
the continuing list, and it won't let me.)

Thanks for any and all help.

[NTG-context] How to make a figure not appear in the list of figures?

[Duncan Hothersall]

Hi folks,

This is probably a simple problem but I can't find an answer.

I have a book with a list of figures and have been asked not to include 
in the list a figure which does not have a caption, even though it has a 
number. So the numbering needs to be sequential, but one of the figures 
needs not to appear in the list of figures.

If I define a new float type Nolistfigure with, e.g.
\definefloat[Nolistfigure][figure]
then it uses its own number, so I get effectively in the text:

Figure 4.11
Blah blah
Nolistfigure 4.1
Blah blah
Figure 4.12

when what I actually want is:

Figure 4.11
Blah blah
Nolistfigure 4.12
Blah blah
Figure 4.13


And then in the List of Figures, I want

Figure 4.11
Figure 4.13

Can anyone get me a quick pointer? As ever, this request has come on the 
release day for this job, so anyone able to help today would be 
fabulous... :-) Thanks.

Re: [NTG-context] How to make a figure not appear in the list of figures?

[Duncan Hothersall]

 Hi Duncan,

 place the figure with the normal \placefigure command, process to whole
 document, delete the unwanted figurelist entry in the tuo-file and 
 process
 the document another time, you can add the --once option in the last run.

 Wolfgang
Aah, nice workaround, thanks. That has got me sorted for today, though 
it would be great to understand, at a more leisurely pace, if there is a 
way to do this from within the .tex file. I was experimenting with 
wrapping the placefigure in something that stopped the list from being 
written, but didn't get anywhere.

Anyway, thanks a lot, this has saved my bacon for today. :-)

Re: [NTG-context] Write once layout everwhere (?)

[Duncan Hothersall]

Hi Pepe,

If you want your content to remain maintainable and manageable for a 
long period (e.g. decades), if you can afford it, and if you have a 
sufficiently large amount of content, then I strongly recommend 
investing the time and effort in an XML-based solution.

My experience is in large scale educational/commercial applications, in 
which managing content in XML and using tools like ConTeXt to create 
beautiful print output, and alternate tools to create web output from 
the same source, is a very good solution. I can certainly let you know 
the technology we use, but some of it is commercial and expensive, and 
other bits are just complicated! I did a talk at the user group meeting 
which was kinda about this: http://context.aanhet.net/epen2007/share/duncan/

The first question to ask yourself is how much effort is your content 
worth. The rest of the answers flow from that, in my experience. :-)

Duncan
 Hello,

 I have used ConTeXt in the past and I have been very pleased with it
 and the results obtained, much more than LaTeX.

 Now I am looking into a solution that would allow me to layout the
 content ConTeXt and in other formats that ConTeXt does not (Forgive my
 ignorance, if I am wrong) output, like HTML, Plain Text, or RTF (Those
 are the formats that I can think of that are interesting to me
 currently).

 Reading the Wiki one of those solutions would be XML, but I know very
 little about the subject, so this email is to ask about experiences in
 similar endeavors, other solutions for the same problem and how
 practical this is.

 I suppose that I would use this for general writing and for academic
 as well (Maths and engineering).

 Thanks,
 Pepe

[NTG-context] Colour (color) in mathml

Hello.

I'm trying to implement part of a change-tracking system using colour to

thought I could do just simply
mi color=greenx/mi

elements of a MathML equation?

[NTG-context] Splitting a float that isn't a table

[Duncan Hothersall]

I define a floating block called Exhibit

\definefloat[Exhibit][table]

which just contains paragraphs of text. I'd like to be able to split it
using the \splitfloat mechanism but that only seems to work if the
content of the float is a table, not paragraphs.


\definefloat[Exhibit][table]
\starttext
\input tufte\par
\splitfloat[lines=auto]{\placeExhibit{Knuth}}
{\dorecurse{4}{\input knuth \par}}
\input tufte\page[yes]
\stoptext


This outputs there is nothing to split in the resultant PDF.

Is there any way to achieve the equivalent of


\definefloat[Exhibit][table]
\starttext
\input tufte\par
\splitfloat[lines=auto]{\placeExhibit{Knuth}}
{\bTABLE[frame=off]\dorecurse{4}{\bTR\bTD\input knuth \eTD\eTR}

without having to make every paragraph a table cell?

[NTG-context] Giving a float its own number

[Duncan Hothersall]

I have a book with parts and chapters; figures in the chapters are
numbered 1.1, 2.1 etc. but sometimes a part has a figure in it as well,
before the chapters start. The desired numbering for such figures is to
follow the Part numbers, and be in capitalised roman numerals (in other
words, Figure II would be the figure in the intro of Part 2).

So I define a new clone of figure called Partfigure, and give it the
necessary setups to make the numbering come out in cap roman; and I
thought the easiest way of managing the number itself would be just to
increment it each time \part is called. (Not every part has a figure.)

But I can't seem to get the number to come out when I place the figure.

Minimal example below (I have culled the actual \parts and just put in
two increments, but the effect is the same).


\definefloat[Partfigure][figure]\definenumber[TrackingPartfigurenumber]
\setuplabeltext[en][Partfigure=Figure ]
\setupnumber[Partfigure][number=TrackingPartfigurenumber,conversion=Romannumerals,way=bytext]
\setupcaption[Partfigure][style=\bf,numberstyle=\bf,headstyle=\it,align=middle,location=bottom]

\starttext
\incrementnumber[TrackingPartfigurenumber]
\incrementnumber[TrackingPartfigurenumber]
TrackingPartfigurenumber now equals
\rawnumber[TrackingPartfigurenumber], which will display as
\convertednumber[TrackingPartfigurenumber]. But it doesn't get used:
\placefloat[Partfigure][here][-:PMRWFII]{A cow}{\externalfigure[koe]}
Why not?
\stoptext


I tried also \increment[Partfigure] but this produces exactly the same
output.

I also tried using ownnumber=true in the Partfigure setup and then
feeding it the value {2} in the \placefloat call but that wouldn't compile.

Where did I go wrong? I'm sure there is an easy way to do this.

This one is a bit desperate, again, a very fussy author is waiting on
it, so...

Thanks all.

I want to differentiate sub-entries, which each have an indent of 1em

a short entry
  a sub-entry
quite a long-winded single entry

quite a long-winded
  single entry

I have been fighting with this one for ages, and have now narrowed down
the culprit, but I do not understand why it happens.

Latest (non-beta) ConTeXt, also tested in the live garden (same result):


\setupcaption[figure][align=right,location=bottom]

\placefigure[here]{\vtop{\hsize=105mm \dorecurse{12}{sample content
}}}{\framed[width=\textwidth,height=50mm,align={middle,lohi}]{sample}}
\stoptext


As it stands, this produces the expected output (a table and a figure
each with long captions, with the captions set 'hanging'). However, if I
define a totally unrelated textbackground (uncomment the third line),
both captions veer off upwards, apparently a distance related to the
number of lines in the title (play with the dorecurse numbers to see the
effects).

It doesn't seem to matter what the background is called, whether or not
it is ever used, or what parameters it is given.

I have no idea why something seemingly unrelated is having this effect;
some reuse of a variable or unreset value somewhere?

I would be really grateful if someone could [tell me how to] fix this.

[NTG-context] Rule under length of last line

[Duncan Hothersall]

I've had a last-minute impossible request for a typesetting style, and
having already told the person it can't be done in the time available,
wondered whether it can actually be done at all.

The request is for a subsection heading to have a continuous horizontal
rule under both its number and title, at a distance of about 6pt from
the baseline (i.e. not underlining), extending just the length of the
heading. I can do that by setting both number and title in a TABLE,
setting the offsets and specifying the bottom frame to be on - no problem.

However, the tricky part is that where a longer title runs beyond one
line, the line should only appear under the last line, and only to the
length of the last line of text.

In other words, for viewers with fixed width fonts:

1.1.1 Short title
-

1.1.2 Longer title which wraps onto a
  second line like this
---

We generate the ConTeXt code from XML, so ideally a solution wouldn't
require the last line to be set separately, but would just work whether
the heading was single or multiple line. What I'm really looking for is
a subsection setup that will automatically do this whatever length of title.

I have to say I think it's quite ugly, but can anyone give me a pointer
as to how it could be done? Is there a box left at the end of a par
which shows the width of the last line?

As I say, I've already said no, so this is just out of interest, no
urgency.

Thanks,

Duncan

Re: [NTG-context] Rule under length of last line

Wow, very cool. Will adapt and wikify. Thanks - it's even better to say
no and then do it anyway. :)

Thanks again.

 Dear gang,
 
 I have redone this. Now there are two filter sequences, one for main text
 and one for using the arabic-font digits in math mode.

 has been updated, get the new uni2cuni.zip. I'll update m-gamma soon so
 this will be part of the distro if Hans accepts-)

I'm very grateful for all the effort on this. I had some trouble
installing the new ConTeXt beta to test it at the weekend and spent most
of Sunday trying to understand why... But at least I am now in a
position to be a tester of the new filter sequences together with the
new beta. My revised test files are again at

http://www.capdm.com/public/context/figtest.tex
and
http://www.capdm.com/public/context/figtest.pdf

these were regenrated this morning with the latest versions of everything.

Please note that I had to remove the \isolateseparators in order to see
my alternative - separator; with \isolateseparators specified the dot
stayed resolutely in place. But the great news is that this also makes
the figure reference work, which is fantastic. Note that there is now no
need for \reversesectionnumberstrue.

Idris, I pasted your maths stuff into the preamble and the test content
as well; is this what you expected to see from your test? I wasn't sure,
but it looks good to me.

Thanks again. Happy to test further for anyone/anything.

Hans, in Friday's beta, core-sec.tex line 767 has

\edef\levelstring{=\flistsectionseparator\@@filternumberpart[#1]\sectionseparator}%

which fails not knowing what \flistsectionseparator is. Reverting to

\edef\levelstring{=\sectionseparator\@@filternumberpart[#1]\sectionseparator}%

works but may not be the intended effect.

Re: [NTG-context] Question about Captions

[Duncan Hothersall]

 I'd like to know whether it is possible to control the captions of
 tables and figures separately. What I wanna do is to place the
 caption above the table but below the figure.

\setupcaption[figure][location=bottom]
\setupcaption[table][location=top]
