Re: [NTG-context] numbering questions

[Duncan Hothersall via ntg-context]

I can't test right now but would something like

\setuphead[Day][sectionsegments=Day:Month:Year]

help?

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.

I found this unanswered question on the list from November 2020 and find

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.

Duncan

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


MWE:
--

\startbuffer[demo]

instruction.

 \xmlsetsetup{#1}{*}{xml:demo:*}

\startxmlsetups xml:demo:book

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?

[Duncan Hothersall via ntg-context]

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.)

Re: [NTG-context] A book with sections

[Duncan Hothersall via ntg-context]

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.
