[NTG-context] Prefix the text in an enumeration.

[Gerion Entrup]

Hi,

is there a way to automatically prefix the text body in an enumeration?

Consider this example:
```
\defineenumeration[question][
alternative=top,
text=Question,
title=yes,
titleleft=,
titleright=,
right={:},
headstyle=bold,
]

\starttext

Some text:

\startquestion[title={How long does a loop last?}]
\bold{Answer:} For a while.
\stopquestion

\stoptext
```

I'd like to have the `\bold{Answer:}` automatically. So for example something 
like this:
```
\defineenumeration[question][
alternative=top,
text=Question,
title=yes,
titleleft=,
titleright=,
right={:},
headstyle=bold,
prefix={\bold{Answer:}},
]

\starttext

Some text:

\startquestion[title={How long does a loop last?}]
For a while.
\stopquestion

\stoptext
```

I tried to misuse `inbetween` for that but `alternative=top` seems to make a 
(not modifiable space) between the heading and the text body.

Best
Gerion

[NTG-context] How to improve appearance of bars in frac, sqrt, etc. on screens?

[Ralph]

Hello,


I’m relatively new to ConTeXt (version 2024.05.31, LMTX, standalone) and 
really enjoy learning it so far, but I have one little problem with the 
appearance of horizontal bars in math mode.


It seems the way ConTeXt displayed horizontal extensible bars in math 
mode some time ago (as used in \frac, \sqrt, \overbar, ...) was similar 
to the way LaTeX (PDFLaTeX and LuaLaTeX) and Plain TeX handled this, but 
it has changed since then. Instead of one bar there are now multiple 
characters attached to each other.


This makes it look more consistent with the font, but unfortunately it 
doesn’t display well in any PDF viewer I’ve tried (on Linux, so I’ve not 
tried Adobe Acrobat Reader). The bars look dotted, I guess it’s due to 
anti-aliasing (the dots disappear when anti-aliasing is disabled, but 
then of course everything looks pixelated). Two screenshots are attached 
(different zoom levels in PDF viewer) so that you know what I’m talking 
about.


Source:
\setuppapersize[S3]
\starttext
\startformula \sqrt{a^2 + b^2} = \frac{1000 \cdot c}{1000} \stopformula
\stoptext

Is there a way to switch to the old bars for documents viewed mainly on 
screens, or is there any other way to improve their appearance? I 
couldn’t find any documentation on this, so I would be very thankful if 
somebody here could help out.



Best,
Ralph

After sending my message, I saw that the Gardener group seems to have
permissions to delete pages (not sure about user pages).

I wonder whether this may constitute a formal request (for me and Max
[always when he agrees]) to be considered as candidates for Gardeners.

I know that this is not a privilege, but I would like to be able to
remove spam from the wiki.

Many thanks for your help,

I also don't have deletion privileges, but I went through the recent
pages and deleted the spammy content. These edits should all show up in
"Recent Changes", so _hopefully_ this makes it easier for the Wiki
admins to delete. (If removing the spam makes it harder for the admins
to delete it, please let me know and I won't do it again).

[NTG-context] comment on the wiki

[Pablo Rodriguez via ntg-context]

Dear wiki maintainers (Taco at others),

I have found in the user creation log:

05:40, 7 June 2024 User account FelicaEnyeart34 was created
22:59, 26 May 2024 User account NonaAlber414387 was created
04:33, 26 May 2024 User account Tony83264596 was created
15:17, 24 May 2024 User account WallyGarth was created

I‘m afraid these four users may be only spamming accounts.

I don’t know whether it is worth discussing this issue, but I have two
questions:

Is there any way in which regular wiki contributions may help in
removing the accounts or at least all the pages generated with these
accounts?

Is there any way to fix the display of user contributions (such as mine,
https://wiki.contextgarden.net/Special:Contributions/Ousia)?

I have just discovered that the problem is to search for contributions
in all namespaces (set by default), which triggers the error message:

  Namespaces with negative values are not supported.

If main namespace is selected, everything works fine.

I wonder whether it would be possible to set the main namespace as
default to search for user contributions.

Many thanks for your help,

Pablo

A *very* quick and hacky implementation. First, clone the repository

Then, install all the files somewhere where ConTeXt can find them. The

[NTG-context] Cite-proc Lua - Following up

[hdanielhixson]

Hello all,

I hope you are well. This is my first time posting. So if I do so erroneously, 
I apologize. 

There is a LaTeX package called citation-style-language, backed by some 
software called citeproc-lua. The github page for the software is here: 
https://github.com/zepinglee/citeproc-lua

It is an excellent piece of software.

There was previous discussion about potentially integrating the software into 
Context. The following link should show a discussion that took place about the 
topic.
https://www.mail-archive.com/search?l=ntg-context@ntg.nl=subject:%22Re%5C%3A+%5C%5BNTG%5C-context%5C%5D+Citeproc%5C-lua%22=newest

I'm just wondering if there is more news about its potential integration with 
Context.

Thank you, devs, for your hard work on making the software.

[NTG-context] suggestion: two templates for the wiki

[Pablo Rodriguez via ntg-context]

Dear Taco and Hraban,

trying to improve the XML page from the wiki, I think it would be
extremely useful to have two templates for inline code:

{{xml|…}}: inline XML highlighted as  for blocks.

{{tex|…}}: inline TeX code highlighted as  for blocks.

As for the second, {{cmd|…}} includes a link (not always required) and
doesn‘t higlight more than the command itself.

Let me know whether I can contribute in any way to this.

Many thanks for your help,

Pablo

[NTG-context] Re: get measures as dimension in Lua

[Henning Hraban Ramm]

Thank you, Max, for the effort and Hans for a core solution!

Indeed we can have:

     local namespace = tokens.getters.macro("??measure")

     return value .. "sp"

and when you want to avoid the namespace you can do:

     if asdimen then

which is some 4 times slower. It'sindeed not documented (although there 
are some examples in accessors-001.tex) but it's in one of my todo's 
because I can use it in some places (there ar emopre such todo's) after 
which it will be discussed in one of the lowlelvel manuals


i'll add tex.getmeasure to the core (but a bit different)


Not to be misunderstood, I couldn’t check yet, maybe I wasn’t clear:

I need to process the measure as a dimension, like \measured{Bleed}.

As far as I tried, neither tex.measured nor context.measured worked (but 
I wouldn’t swear on it, maybe I had a different error).

[NTG-context] get measures as dimension in Lua

[Henning Hraban Ramm]

Hi,
when I define a measure on the TeX side, I used to get at the value in 
Lua with tex.getdim, like:


\definemeasure[Bleed][3mm]

tex.getdimen("Bleed")

But now I get "incorrect dimen name".
I need it as a dimension, since I do calculations with other dimensions 
like "topspace".


How should I do this correctly?

(I just assume this used to work – the code is old any maybe stuck in an 
intermediate state where I switched from \newdim to \definemeasure…)

[NTG-context] regular online meet-up

[Henning Hraban Ramm]

I nearly forgot:

You’re invited to our regular online meet-up, this upcoming
Wednesday, June 12th, 19:00 CEST (UTC+2)

at https://lecture.senfcall.de/hen-rbr-rku-oke
(same, but shorter: https://u.mtxrun.eu/ctxmtg)

ConTeXt users of all levels are welcome!

Do you have a subject that you’d like to talk about?

Looking forward to seeing you,
Hraban


(Same blurb as always:)

[Howto]
* No special software installation required; most modern browsers should 
work (WebRTC required).

* Open the URL above, accept the privacy statement,
* enter your name,
* click "join" (or "start" if you’re the first),
* click "with microphone", allow your browser to access it, check the audio.
* Your microphone is muted if you join. Activate microphone and/or 
camera with the buttons at the bottom.

* Minimize the default presentation with the "screen" button, bottom right.

* If you’d like to share your screen or upload a file, you can make 
yourself the presenter: Click on your user name, change the setting, 
then you’ll see the "screen sharing" button beside the camera button; 
also there’s now "manage presentations" behind the "plus" button.
Beware there is only one presenter at a time, so don’t kill someone 
else’s presentation.


[Technical hints]
* Sound is usually better if you use a headset (less noise for everyone).
* Connection problems are mostly due to low bandwidth or high latency on 
your side, e.g. with mobile connections.

* Sometimes leaving and re-entering helps.
* If audio/video doesn’t work for you, you can still use the text chat.
* Screen sharing needs a lot of bandwidth.
* BigBlueButton documentation applies: 
https://bigbluebutton.org/teachers/tutorials/


[Netiquette]
* Please use a name that we recognize from here. Some feel uncomfortable 
with anonymous lurkers.

* Mute your microphone while you’re not talking.
* It’s nice to show your face at least when you join.
* If there are connection problems, stop camera sharing.
* The room is set to “everyone’s a moderator“, I trust you...

Try something like:

   [method=dataset,
sorttype=index,
filter=match(category:article)]

I have used the filtering mechanism to select fields, such as 
filter=match(year:2023).

As for the color, it is caused by \setupinteraction.

You can remove it with:

  \setupinteraction[state=start, style=, color=, contrastcolor=,]

This disables default style and color in links (footnote markers are links).

I hope it helps,

as you can see the note number has same style all over the document.
but i want it to have style base on current font
and if the font changes, the style should change, while maintaining the 
ratio of sizes(i.e., at the half of current font).

i attached the resulted pdf


1. You can use the \offset command to raise the footnote number.

2. Disable the value of the textstyle to ensure you get current style 
for the footnote number.


 begin example
\define[1]\MyNoteTextcommand
  {\offset[y=-0.2ex]{#1}}

\definenote
  [Mynote]

\setupnote
  [Mynote]
  [location=text,
   textstyle=,
   textcommand=\MyNoteTextcommand]

\starttext

\input{knuth}\Mynote{First note.}

\startstyle[style=\ss]

as you can see the note number has same style all over the document.
but i want it to have style base on current font
and if the font changes, the style should change, while maintaining the
ratio of sizes(i.e., at the half of current font).

Not sure I’m getting your point.

But this should show a difference in font size:

  \definenote[Mynote]
  \starttext
  \color[green]{\tfd hello \Mynote{refrence} not really required}

  \switchtobodyfont[36pt]
  \color[green]{hello \Mynote{refrence} not really required}

Could you show how the second paragraph above doesn‘t inherit both size
and color from the current font?

Sorry, otherwise I simply don’t get it.

I don’t think the text command value is right.

Besides, if you intend the second paragraph from the sample, this
approach looks unnecessarily complex for me.

I hope it might help,

[NTG-context] Scale notation base on current font

[seyal . zavira]

Hi all,

There's a problem when I want to define the note so that it's displayed 
according to the size and font of the text:

this MWE change the notation size:
\definenote[Mynote][location=text,before={},]
\setupnote[Mynote]
[location=left,
 textcommand=\tfb \raise 0.2ex\hbox,
]
\starttext
hello \Mynote{refrence}
\placenotes[Mynote]
\stoptext

but i cannot set it for \tfxx.
also it's relative to my main body font, and my current font and color doesn't 
apply to text.
for example if my current text has color red with another font the note doesn't 
change according to it, and will display identical everywhere.

And when I try to define it like this MWE:

\definenote[Mynote][location=text,before={},]
\setupnote[Mynote]
[location=left,
 textcommand= \scale [height=0.7ex] \raise 0.2ex\hbox,
]
\starttext
hello \Mynote{refrence}
\placenotes[Mynote]
\stoptext

it doesn't work.

how i should define such notes?

Many thanks for the new reference, Wolfgang.

I’m going to fix the wiki links right now
(https://wiki.contextgarden.net/XML).

As this comes from

seems to be previously defined on This comes from
https://wiki.contextgarden.net/images/8/8c/xhtml.pdf#page=10, I would say:

   {\externalfigure[\xmlatt{#1}{src}]

make sense).

Have a look at the XMl related articles in

Thomas’ “Presentations in XML” is a good introduction IMO.
Taco’s articles are more specialized but give further insights.

If you are familiar with XSLT (and XPath), you will have no problem
typesetting XML sources with ConTeXt.

Well, xml-mkiv.pdf isn’t exactly a piece of cake. It isn’t an
introduction and it has to be written that way.

After trying to read it for the n-th time and having learnt only very
little from it (exclusively my fault), I think it assumes a good XPath
background.

Again, xml-mkiv.pdf is documenting the way of handling XML in ConTeXt
and it has to be written that way.

It is part of our task (the one reserved to final users) to compose a
proper introduction on how to typeset XML sources with ConTeXt.

Borrowing the title from other work, “XML in Proper ConTeXt” (actually
taken from https://www.berenddeboer.net/tex/LaTeX2ConTeXt.pdf).

All I can say is that I have read xml-mkiv.pdf and I know I will learn
way more from this document than the huge amount of things I have
already discovered reading it.

Sorry for insisting. If the text is not fully formated, it is very easy
to overlook formatting errors with commands (or simple errors with
commands directly).

The most basic sample may read (wrong spacing after command):

  \starttext
\ConTeXt is awesome!
  \stoptext

This is one in a bunch of errors that may be unnoticed.

Just in case it might help,

Pablo

1. \setcharacterspacing[frenchpunctuation] takes care about the space 
before/after quotation marks when you use manual quotes in a document.


It doesn't matter whether you use or don't use space between the 
quotations marks and the quoted text.


 begin example
\starttext

\startlines
«quoted text»
« quoted text »
\stoplines

\setcharacterspacing[frenchpunctuation]

\startlines
«quoted text»
« quoted text »
\stoplines

\stoptext
 end example

2. When you use the quotation command or environment ConTeXt adds a 
space between the quotation marks and the quoted text by itself but in 
the quotation-environment the space before the closing mark disappears 
when you add \setcharacterspacing.


 begin example
\language[fr]

\starttext

\startquotation
quoted text
\stopquotation

\quotation{quoted text}

\setcharacterspacing[frenchpunctuation]

\startquotation
quoted text
\stopquotation

\quotation{quoted text}

\stoptext
 end example


Is \setupquotation[symstyle=\resetcharacterspacing] necessary?


It's a temporary fix for the problem with the quotation environment by 
disabling the characterspacing mechanism when ConTeXt places the 
quotation marks.

It seems, that this workaround solves the problem:
\setupquotation[before={\setcharacterspacing[reset]}]



The quotation environment doesn't rely on the characterspacing mechanism 
to add the spaces before and the after the quotes but uses language 
dependent skips.


The example below shows how it works and where it fails when you use 
characterspacing. Resetting spacing (and probably other settings like 
charcterkerning etc.) when the quotes are added as you noticed fixes the 
problem.


 begin example
\starttext

\dontleavehmode
\hbox{«\hspace[fr][quotation]}%
xxx%
\hbox{\hspace[fr][quotation]»}

\setcharacterspacing[frenchpunctuation]

\dontleavehmode
\hbox{«\hspace[fr][quotation]}%
xxx%
\hbox{\hspace[fr][quotation]»}

\dontleavehmode
\hbox{\expand\everyresettypesetting\relax «\hspace[fr][quotation]}%
xxx%
\hbox{\expand\everyresettypesetting\relax \hspace[fr][quotation]»}

\stoptext
 end example


What do you think about it? Is this the right way to do it?


I would use the symstyle key as hook to disable charcterspacing for the 
quotes in the environment.


 begin example
\mainlanguage[fr]

\setcharacterspacing[frenchpunctuation]

\setupquotation[symstyle=\resetcharacterspacing]

\starttext

It seems, that this workaround solves the problem:
\setupquotation[before={\setcharacterspacing[reset]}]

What do you think about it? Is this the right way to do it?

For me, Wolfgang's answer fulfills all my needs.
So, from my point of view, this is not needed anymore.

[NTG-context] ConTeXt source from XML

[Christoph Edenhauser]

Dear Pablo,


Dear Christoph,

just in case it might help to your meditation.

First of all, lpaths are XPath implemented with Lua in ConTeXt.

XPath seems to have as it primary purpose to address the nodes of XML trees.

About your sources, the real issue here is to define whether you want
TEI or TeX to be the format containing them.

I mean, if you add explaining footnotes to your TeX file(s), XML won’t
be source anymore.

If you don’t want this to happen, you have to encode them in the TEI XML
sources.


In my case, the connection to the original source will be lost. While we 
will still try to backport corrections, the connection will be lost at 
the very moment when we will annotate the source text.
From this point of view, an independent source is created here anyway, 
so I have the freedom to choose between TEI or TeX.
At the moment I'm leaning strongly towards TEI, also because I could try 
to remove the annotations via XSLT once the work is complete, diff the 
result with the original source and improve it). And besides, 
XML+ConTeXt looks quite elegant from the distance of my ignorance. 
(Although reading xml-mkiv.pdf creates a pleasant frictional heat in my 
cerebral convolutions, but leaves at least as many knots in them as XML 
data have nodes).



One last suggestion about proofreading. This is something I learnt from
personal experience.

The first reading is much better to catch errors in the text than the
subsequent ones.

Having the text properly formatted and printed on paper helps a lot to
spot errors.


Same here: It's the paper!
(I for myself prefer for the first proof reading a page lots of white 
space, in monospaced font like Courier, while my proofreader wants to 
see the font that will be used in the end.)


Thank you very much for your suggestions,

Christoph

Really cool! Thank you. If I see it right, this is completely generic,
so with this it is possible to define any start stop
with completely variable arguments.

\startuseMPgraphic{background:test}

Aditya,

thanks for the information.  So far (in my ConTeXt journey) I haven't seen
anything with doing that, but I appreciate the advice.

I don't understand the full Zen of \dontleavehmode (in my poor
understanding I think it should be called \ensurehmode or something like
that), but given that I explicitly used \noindent, is that not an analogous
thing?

Thanks.

Jim

Starting a paragraph with a group {...} can lead to unexpected outcome. It is 
better to use \bold{...} here, or \dontleavehmode {\bf ... }.

Thank you very much for your very clear, detailed and elaborate

I think this is already included in

The file from the distribution is the same as the one online (same

Hi Hraban,

That works perfectly.  I didn't know about that command before, and my
google searches to find something like that didn't turn anything up.
Undoubtedly I used the wrong search terms.

I tried putting the \placefigure and the itemize in a box, thinking that if
all else failed I could put a negative \vskip at the bottom to make the box
shorter.  However, when I tried putting all that in a \vbox I got some
error messages which were not immediately illuminating (to me).

Thanks for the pointer.

Did you try \adaptlayout?

It might also help to put the itemize in a box (but that might end up on

[NTG-context] \item would fit, but was pushed to next page. Work-around or fix?

[Jim]

Hi,

I had the following structure which ended up at the bottom of a page:

---

\setupcaptions[number=no]
\placefigure[right]
{blah blah blah}
{%
\vskip -15pt
\externalfigure[DSC_2782][width=0.32\textwidth]
}
\noindent
{\bf Blah blah blah }
\startitemize[intro,nowhite]
\item blah blah blah blah blah blah!  blah blah blah blah, blah
  blah blah blah blah blah blah blah blah blah.
\item blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah
  blah.
\item blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah.
\item blah blah blah blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah blah.
\item blah blah blah blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah blah blah blah blah blah
  blah.
\item blah blah blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah.
\stopitemize



There was, in fact, room to put the last \item on the page (and even a bit
more), but ConTeXt insisted on moving the last \item to the next page.  I
assume that its calculations were a bit conservative for whatever reason,
but I really wanted the last item to be on the same page as its friends.

I tried some "tricks" that would have worked for me in plain TeX, but
ConTeXt was having none of that.

Q1: Is there a Right Way to force ConTeXt to put an \item on the current page?

Q2: If not, does anyone wish to suggest some way to trick ConTeXt here, or
to do an end-run around its calculations?

Note: to solve this problem the use of brute force has been authorized.

Thanks.

Hi, I don’t find it hard to understand, but I don’t think it’s possible

well, as one needs to do some work one can as well do this:

% oeps.tex

\startbuffer[test]


test


\stopbuffer

\startxmlsetups xml:mysetups
\xmlsetsetup{\xmldocument}{*}{xml:*}
\stopxmlsetups

\xmlregistersetup{xml:mysetups}

\startxmlsetups xml:what

\stopxmlsetups

\setuppapersize[A1]
\setupbodyfont[dejavu,ss,1pt]
\setuplayout[tight]
\setupalign[verytolerant,flushleft,nothyphenated]

\starttext
\xmlprocessbuffer{main}{test}{}
\stoptext

and then run

>context oeps
>mutool draw -F txt oeps.pdf

and get

\StartSomething
\StartWhat
test
\StopWhat
\StopSomething

so now you need to wikify it ...

Hi Christoph,

as far as I know (and as Hraban has already mentioned), this is not
possible.

Either XSLT or pandoc would be a way to do that.

That being said, I would avoid conversion (a second source) in all cases.

I use ConTeXt to typeset XML sources typing Markdown sources.

pandoc generates XML and then ConTeXt typesets these XML sources.

Different spaces are Unicode characters. As entities,  or 
(narrow no-breaking space and thin space, respectively).

I don’t mean the proofreader personally, but TeX code may not be
inherenlty more readable that XML code.

Compile the following:

  \starttext
  \startXML
  
  St.Martin
  A comprehensive treatise
  The medieval part of the church
  \stopXML

  \startTEX
  \starttext
  \startchapter[title=St.\, Martin] \stopchapter
  \startsection[title=The medieval part of the church]\stopsection
  \stoptext
  \stopTEX
  \stoptext

I think that a text editor with reasonable highlighting for XML is key
to your issue.

I mean, XML sources tend to be highlighted leaving pure text as
uncolored and unformatted (no bold or italics).

In that case, I think the text to be proofread may be recognized as not
having any format at all (besides not enclosed inside "<" and ">").

> And now a second approach to my question:
> Are all these \startxmlsetups like '\startxmlsetup xml:chapter'

No, these are formatting commands after the mapping.

In short, there are three steps involved in XML typesetting.

First, you select which elements you would like to select from the XML
source in an XML setup (with a mapping to your configuration commands).

Second, you register this XML setup.

Third, your configure the selected elements with ConTeXt commands.

Here is a sample (using a buffer instead of an external file):

  \startbuffer[demo]
  
 line 1
 line 2
 line 3
  
  \stopbuffer

  \starttext

  \startxmlsetups abc:def
\xmlsetsetup{#1}{foo|bar}{xyz:*}
  \stopxmlsetups

  \xmlregistersetup{abc:def}

  \startxmlsetups xyz:foo
\xmlflush{#1}
  \stopxmlsetups

  \startxmlsetups xyz:bar
\startparagraph
  \xmlflush{#1}
\stopparagraph
  \stopxmlsetups

  \xmlprocessbuffer{main}{demo}{}

  \stoptext

First of all, XML has no hardcoded names for any element (from a certain
point of view, XML are only rules on how to use the "<>" tags).

This is why,  and  are perfectly valid element names (although
they have no meaning for people).

Second, the mapping may use any name for destination setups.

\xmlsetsetup does the mappings, the second group of parentheses contains
the lpath (an Lua version of XPath [how XML is selected]) and the third
group of parentheses is setups.

The command \xmlsetsetup{#1}{foo|bar}{xyz:*} above is bound to existing
elements (or paths) in the XML source, but both "xyz:foo" and "xzy:bar"
may read as the user wants.

Third, after that you need specify the setup for each mapping (or it
won’t appear in your final document).

The setup is what you defined as the second part of the mapping, may it
be "xml:title" or "xyz:bar".

Nothing here is hardcoded. XML is not HTML (elements with meaning).

In order to deal with XML, ConTeXt has to provide the tools to select
elements (and more complex constructs) and map them to configurable setups.

How both tools (construct selection and setup configurations) may be
deployed, this is up to each individual.

Hardcoding this would be a real problem in the short run.

> If this is the case, can this intermediate context representation be
> exported, and how would this be done?

Nice try, but I’m afraid this is not how it works.

I hope my explanation may be minimally clear to understand why your
approach is different from what ConTeXt offers.

Feel free to ask, if my explanation wasn’t clear enough.

I hope it helps,

Pablo

You can use \definehighlight to create a custom command for a style.

The case where you want a slash before the text you have to use 
\definestartstop which allows you to set something before and after


\definestartstop [cmdi]   [style=\tt,left=\textslash]
\definehighlight [cmdii]  [style=\tt]
\definehighlight [cmdiii] [style=\rm]

What do you mean with “not properly”?

\cmdi is not defined
Only \cmd has the necessary additional braces to contain the style switch.

Hi, I don’t find it hard to understand, but I don’t think it’s possible 
within ConTeXt (while Hans keeps surprising me).


Maybe try XSLT or pandoc.

The latter can already read DocBook and write ConTeXt; it doesn’t read 
TEI (yet). There are also XSL style sheets for TEI, e.g. 
https://github.com/TEIC/Stylesheets


I don’t know if you would loose too much information going 
TEI-(something else)-ConTeXt. Maybe it makes sense to adapt the LaTeX 
stylesheets.

I have the following workflow in mind:

And here comes my question: Can I use context to convert my XML-file

What do you want to tweak. HEre is the lowest level approach:



    test 1
    
    
    test 2
    
    test 3


But quite some can be done when processing and there are mechanisms to 
inject e.g. page breaks using processing instruction. Probablyh not 
all is documented.


There is a xml-mkiv-tricks.tex file in the distribution (no pdf is

I realise that it is somehow difficult for me to describe what I would 
like to achieve, perhaps what I have in mind is not even possible.


Let' say i have an xml File with something like this


St. Martin
A comprehensive treatise
The medieval part of the church

I would now like to create a first file1.tex with all the necessary 
xmlsetups like e.g. something like this


\startxmlsetupsxml:chapter
\startchapter[title={\xmlflush{#1}}]\stopchapter
\stopxmlsetups
\startxmlsetupsxml:section
\startsection[title={\xmlflush{#1}}]\stopsection
\stopxmlsetups

I can now generate a pdf file with context. But:

My Question is, is it possible to generate a second context file2.tex 
with the help of this first xml-mapping file1.tex, where all the 
xml-nodes from the xml file are mapped to contex commands which then 
looks something like this:


\starttext
\startchapter[title=St. Martin]\stopchapter
\startsection[title=The medieval part of the church]\stopsection
\stoptext

I would then like to edit the Text in such a more "TeXish" result  
manually, e.g. insert small spaces as in ‘St.\,Martin’, explain unknown 
words in \footnote{comment}, etc.


I know you could or even should do the text corrections in the xml file, 
but XML would overwhelm my proofreader. (He has learnt to leave LaTeX 
code untouched, that should then work with ConTeXt code as well). So for 
me, the main reason for having a TeX-ish file2.tex is, that the Text 
could be corrected directly from the proofreader in this file2.tex file, 
but won't do that in the xml file.


And now a second approach to my question:
Are all these \startxmlsetups like '\startxmlsetup xml:chapter' 
internally mapped to standard context commands like \startchapter ... 
\stopchapter before they are converted to pdf?
If this is the case, can this intermediate context representation be 
exported, and how would this be done?


Thank you very much for your help,

best regards, Christoph

Hi Christoph,

not clear to me whether you meant an environment (a format file) with
the ConTeXt generated file.

In that case, this might help:

   context --extra=xml --analyze --template your-file.xml

With that template, you may run:

   context --environment=xml-analyze-template.tex your-file.xml

BTW, there are two typos in xml-analyze-template.tex (lines 8-9):

   - \startxmlsetup should read \startxmlsetups.
   - \xmlsetsetups should read \xmlsetsetup.

But consider that this only flushes text with no formatting (you will
have all text in a single paragraph.

If this is not what you need, a more detailed (or simply more verbose)
explanation) might help.

Just in case it might help,

That one's on me, thank you. Unfortunately, this does not fix the main
issue. Checking the MWE's logs reveals that the splitting command found
nothing to split, even if there's enough text for multiple pages. My
best guess is that something goes awry when checking how much vertical
space is available, since uncommenting the filler line leaves no space
for an additional line in the page.

Thanks again.  Without looking at the code, I (boldly) conclude that the
bullet is in an \hbox.

While I'm curious about why text in an \hbox is printed, I'm thinking that
I may not have need to know.  ;-)

The reason why you get no text isn't that you wrote it before \starttext 
but that no font was loaded yet. By default ConTeXt postpones the 
loading of the default fonts until \starttext because when you use a 
different font on your document this is normally before \starttext and 
with the postponing there is no need to load a unused font.


At the point where you load a font with \setupbodyfont text even if it

If you (or some other knowledgeable person reading this) don't (doesn't)

Is the bullet symbol not from some font?  If so, why is that font loaded in
time to see the bullet?


When no font has been loaded yet with \setupbodyfont ConTeXt prints text 
which is put in a \hbox in a monospaced font as shown in the example below.


 begin example
This is before \tex{starttext}.

\hbox{This is also before \tex{starttext}}

\starttext
This is after \tex{starttext}.
\stoptext
 end example

Hi Wolfgang,

Thanks for the (prompt!) answer.

I did not realize the wiki software did that.  On reflection I suppose that
is useful in many (most?) cases.  But I'd argue that it is not always a good
thing, such as in this case.  (If nothing else, it might mislead a n00b
into thinking that you should get output for text preceding \starttext.)

If you (or some other knowledgeable person reading this) don't (doesn't)
mind another question,...
Is the bullet symbol not from some font?  If so, why is that font loaded in
time to see the bullet?

And finally, might it make sense for the wiki software to do something like
this:
if grep '\\starttext'  >/dev/null 2>&1
then
process the example from the wiki
else
augment the wiki example with \starttext and \stoptext
process the augmented wiki example
fi

Cheers.
Jim

The wiki adds \starttext at the start and \stoptext at the end of each 
example

and the \starttext/\stoptext pair which is part is just ignored.

When you try to run the example as is there is no text before \starttext 
because

no font has been loaded yet (you can add \setupbodyfont[modern] before
\startitemize to make the text visible).

TL;DR: OMG! I thought Ubuntu was supposed to be Linux made easy?

1) I installed Ubuntu 14.04 It comes with context pre-installed but it's broken.

bruce@bruce-VMware-Virtual-Platform:-$ which context
/usr/bin/context

bruce@bruce-VMware-Virtual-Platform:~$ context --version
mtxrun  | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'


2) I removed the pre-installed context, added the reviczky PPA from 
launchpad.net as an alternative package source and re-installed.

bruce@bruce-VMware-Virtual-Platform:~$ sudo apt remove context
[output snipped]

bruce@bruce-VMware-Virtual-Platform:-$ sudo add-apt-repository ppa:reviczky
[output snipped]

bruce@bruce-VMware-Virtual-Platform:-$ sudo apt install context
[output snipped]

bruce@bruce-VMware-Virtual-Platform:~$ context --version
mtx-context | ConTeXt Process Management 1.04
mtx-context |
mtx-context | main context file: 
/usr/share/texmf/tex/context/base/mkiv/context.mkiv
mtx-context | current version: 2023.05.05 18:36
mtx-context | main context file: 
/usr/share/texmf/tex/context/base/mkxl/context.mkxl
mtx-context | current version: 2023.05.05 18:36


This at least works but it's an ancient version. I couldn't find any way to 
access the 2024 dated version referenced in the PPA/launchpad site.


Conclusion:

Not sure where this leaves us. Ubutu complained about the PPA ot having a 
'release' file - so this may be a bug with the PPS config which is stopping 
Ubuntu from downloading from that PPA. Or it may be this will bnever work?

Whatever the problem is, the suggestion of getting Context into the Deb build 
seems like the way to go.

Hi Christoph,

not clear to me whether you meant an environment (a format file) with
the ConTeXt generated file.

In that case, this might help:

  context --extra=xml --analyze --template your-file.xml

With that template, you may run:

  context --environment=xml-analyze-template.tex your-file.xml

BTW, there are two typos in xml-analyze-template.tex (lines 8-9):

  - \startxmlsetup should read \startxmlsetups.
  - \xmlsetsetups should read \xmlsetsetup.

But consider that this only flushes text with no formatting (you will
have all text in a single paragraph.

If this is not what you need, a more detailed (or simply more verbose)
explanation) might help.

Just in case it might help,

Pablo
