Many thanks for your explanation, Wolfgang.
Since \type doesn’t collapse hyphens, wouldn’t it be possible to add
\nohyphencollapsing to \typeinlinebuffer just for the sake of output
consistency?
You can make \typeinlinebuffer behave like \type by adding a second
initializer which besides other things prevents hyphen collapsing.

[NTG-context] upload
Hi,
There is a new lmtx upload.
-- The svg inclusion via metapost has been upgraded and cleanup a bit,
using some more recent metapost features. There are some new (not yet
all documented metapost) features.
-- In the process, support for LCH colors has been added, which is
documented in the (eg luametafun manual).
-- The math manual is not yet there because we were distracted by
improving support for envelopes (penbased outlines) in metafun. This is
still work in progress, some is present and discussed in the manual, and
we'll come back to that sometime next month. Given the next item, we
also might need to change some in the manual (different focus).
-- Because we have users who have to conform to the European
Accessibility Act we have been wondering how to deal with that and at
Mikaels place there are two demands: distinctive colors and tagging and
especially math (somehow validators love to check that). Colors never
were an issue as they can be controlled, and tagging math neither,
especially because nothing was/is done with it anyway, but ... we are
happy that we found a reasonable (more modern and future proof) way out.
As explained / shown in the attached document we're basically forced to
choose a different approach with math (a pity as we worked hard to get
the rendering right but the attached file works fine in the viewers that
we tested).
-- We like to hear from users what other demands wrt accessibility there
are. We're not interested in the (commercial) big money aspects (of pdf
and tagging) nor in the politics behind it (changes over time). What are
the demands, so that we can see how to make it work or just work around
it (as it's kind of boring to cook uyp complex features , esp compared
to playing with metapost).
-- Furthermore .. the usual bits and pieces as discussed on the list and
otherwise.
-- If you have troubles (crash) you need to wipe the cache due to a
change in lua bytecode storage (no easy way to catch it).

We're done with math. After years of active development, Mikael and Hans have
decided to quit working on math, and concentrate on \METAPOST\ and handing over
to the next generation instead. We lost our user to the way more popular
alternative (frozen in stone standards). Also, we had it with suboptimal math
fonts, Unicode math not getting improved, MathML constantly being changed,
browsers dealing with math differently every few years, math archives getting
polluted with tons of useless tagged math.
There are other motivations, like the European union imposing strict rules with
respect to accessibility in educational content management systems, and Dutch
schools trying to get rid of math in favor of simple calculus, if at all. This
is
why the next iteration of the engine will no longer have a math engine:
MathLessTeX. Of course, in the beginning \MLTX\ will be compatible with \LMTX,
because we owe that to the users and we need to prototype the new engine anyway.
In order to get an idea of how we will get rid of the disturbing formulas, you
can load the module:
\starttyping
\usemodule[math-goodriddance]
\stoptyping
Until becoming the default setting, the command \typ {\goodriddancemath} will
bring you into \MLTX\ mode while \typ {\badriddancemath} will bring you back to
the obsolete \LMTX\ mode. Like:
\startbuffer
\usemodule[math-goodriddance] \goodriddancemath

\root [3] {x}}, when we have AI around the corner to help us out with simple
and silly
things like the Pythagorean theorem: \m {a^2 + b^2 = c^2}, or even with more
advanced
math like geometric series: \m {\sum_{k = 0}^{+\infty} x^k = 1/(1 - x)}?
We will not support complicated nonsense stuff like:
\startplaceformula
\startformula
F__{1}{2}(a,b;b;z) = (1 - z)^{-a}

\stopplaceformula

The footnote environment is just a fancy way for a command with a

You can put the code in buffer outside of the footnote and type the
content of the buffer in the footnote.
begin example

Since almfixed is based on Knuth's mono, perhaps its visuals of the control characters can be extracted and used as fallback symbols. Yes: For typeset text/printing visualization is generally unnecessary (the point of this thread). 2. \enabletrackers[typesetters.nbsp] gives a colored box, which is at least something..

See below. But some fonts meant for printing have symbols for Unicode control chars -- that poses a challenge. so an inconsistent mess not worth wasting time on (as this is hobbyism only fun can be a motivational factir) But there is a certain consistency -- see below. And some fonts meant for verbatim/editing do not have symbols for the control chars -- that also poses a challenge. AlmFixed, of course, has them. Most minimally decent Arabic fonts have symbols for the Unicode control chars as default, including Scheherazade, Amiri, Uthmanic, and Noto Naskh Arabic -- all free fonts.

So not "an inconsistent mess" -- at least not as far as Arabic-script typography is concerned.

Using some Unicode control characters will be unavoidable to get the rendering effects correct, but the symbols will need to be suppressed. Am thinking/hoping that a ConTeXt-specific font feature can do the trick. Since there appears to be consistency across Arabic fonts in this matter it should not be messy at all, simply a fallback that sends the symbols to some no-man's land.

The upshot is that, for non-Latin scripts, some toggling capability in ConTeXt is important to have -- even inescapable for Arabic-script piblishing. Perhaps others who use Arabic-script or Indic, etc., can chime in.. Am hopeful that we can figure something out!

That's actually something I had never thought of, using PDF comments,
thanks!.
It's a really nice approach, though weirdly it doesn't work on Okular
(Linux+KDE)
for me, even though attachments worked fine. I'll try and see why that
is.
What I had in mind was rather the following:
\starttext
\starttyping[space=on]
def foo(x):
y = bar(x)
if y:
return x
return y
foo(1)
\stoptyping
\stoptext
but with ordinary char32 spaces rather than \textcontrolspace
characters.

Hi André,
I wonder whether I’m getting your point with the following sample:
\showframe
\setupinteraction[state=start]
\starttext
\startbuffer[abc]
def foo(x):
if x == 0:
bar()
else:
baz(x)
foo(x - 1)
\stopbuffer
\comment[location=leftmargin,
space=yes,
buffer=abc,
title={Python code}]
{}\typebuffer[abc]
\stoptext
This might solve what you need. At least, this is the approach that I
use to provide text that can be directly copied.
I’m on Linux and last time I tested on Windows there were extra lines in
the comments.
Just in case it might help,
Pablo

[NTG-context] Spacing issue with \digits in math mode
Hi list,
I have been trying to understand the workings of the \unit command, which is
producing strange spacing in math mode. In an effort to be more systematic, I
began by investigating the related \digit command. \digit works well in text,
but in math mode the comma separators produce unwanted space.
\digits {12,345.67} vs.\ $\digits {12,345.67}$
Below is a one page test document, derived from the code in phys-dim.mkxl.
I think a simple fix would be to treat the comma as “ord” inside a number, but
I don’t know if that is easy or not. I’d also like the space removed from
around the “x" in scientific notation, which might be accomplished the same way.
Thanks for all the work on spacing in math!
Gavin
\setuppapersize[A4]
\showmakeup[mathglue] %\mathspacingmode=1
\starttext
Digits in math mode have problems with comma separators.
\startbuffer
10 \setdigitmode {1} \setdigitorder{0} $\digits {12,345.67e89}$
20 \setdigitmode {2} \setdigitorder{0} $\digits {12,345.67e89}$
30 \setdigitmode {3} \setdigitorder{0} $\digits {12,345.67e89}$
40 \setdigitmode {4} \setdigitorder{0} $\digits {12,345.67e89}$
50 \setdigitmode {5} \setdigitorder{0} $\digits {12,345.67e89}$
60 \setdigitmode {6} \setdigitorder{0} $\digits {12,345.67e89}$
11 \setdigitmode {1} \setdigitorder{1} $\digits {12,345.67e89}$
21 \setdigitmode {2} \setdigitorder{1} $\digits {12,345.67e89}$
31 \setdigitmode {3} \setdigitorder{1} $\digits {12,345.67e89}$
41 \setdigitmode {4} \setdigitorder{1} $\digits {12,345.67e89}$
51 \setdigitmode {5} \setdigitorder{1} $\digits {12,345.67e89}$
61 \setdigitmode {6} \setdigitorder{1} $\digits {12,345.67e89}$
\stopbuffer
\typebuffer
This is typeset as:
\startlines \getbuffer \stoplines
In text, the \type{\digits} command works fine:
\setdigitmode {2}\setdigitorder{0}\digits{12,345.67e89}.
\blank
Suggestion: Within \type{\digits} (and probably \type{\units}) the comma could
be an \quotation{ord} rather than a \quotation{pun}. This appears to be how the
period is handled.
\blank
I personally think the space around the \quotation{$\times$} is excessive,
especially when the number is in a formula.
\startformula
\digits {12,345.67e89} + \digits {12,345.67e89}
\stopformula
I would like the \quotation{$\times$} to also be an \quotation{ord} when used
for scientific notation.

[NTG-context] font fallbacks
Hi,
I thought I could use more than one fallback font, but as soon as I list
fallbacks, they stop working.
In my example, I’d like to take all missing glyphs from Segoe UI
Symbols, and what’s still missing (emojis) from EmojiOneColor,
preferably without specifying the exact range.
Additionally, I want to replace the tilde ~ of LM Modern:

Re: [NTG-context] Failing \doifemptyelse
Willi Egger via ntg-context schrieb am 23.06.2022 um 21:16:
Good evening gurus!
Why is the minimal example failing? i.e. executing always the else-branch?
\doifempty(else) doesn't expand the argument and any argument counts as
not empty. To satisfy the command you can expand the first argument
(\normalexpanded) or you use \doifnothing(else) which expands the argument.

Dear list,
This is a follow-up question on my previous question about Jean-Luc
Doumont and his grid layouts. This time I have concrete questions. I
reverse engineered his slide (slide_grid_overlay.pdf). All his units are
based on inches, because the inch is an integer multiple (72) of the TeX
point. His base unit is 0.1in. I tried implementing the layout first,
but the pdf dimensions do not match the ones I set up. For example the
width should be 8 inches, but the pdf is over 11 inches wide. I wish to
shut off all margins and similar things and only have a text area with
an offset of 0.2in all around the page (see slide_grid_overlay.pdf).
Here is my current attempt:
You have to use the \measured (with a trailing s) command when you need
multiples of a measure value. When you use something like 2\measure{...}
ConTeXt uses the "2" followed by the value of the measure, the following
example demonstrates this in the second output.
begin example
\definemeasure [point] [1pt]
\starttext
\startbuffer
\tex{measure}: \measure{point}
\tex{measured}: \the\measured{point}

[NTG-context] redefining xmlsetups inside a XML document
Hello,
I'm trying to add new templates (xmlsetups) from the XML document itself.
See the attached MWE.
- the XML document is a simple XHTML file
- in the "head" element there's a "script" element with the "type"
attribute set to "text/vnd.context", whose contents are then passed to
\xmlcontext
- the "body" element has a "data-xmlsetups" attribute whose value should
tell which xmlsetups is to be applied on the body contents (it's defined
in the "script" element above)
If it worked, the resulting PDF should show the body element, followed
by a "Hello world!" paragraph written in red.
But it does not work, because there's something I'm missing in the
redefinition and application of xmlsetups.
To try the MWE, type:
context --environment=nested-xmlsetup.tex --forcexml nested-xmlsetup.xhtml
Massi\startxmlsetups html
\xmlsetsetup{#1}{{html|head}}{html:flush}
\xmlsetsetup{#1}{{html head script}}{html:script:context}
\xmlsetsetup{#1}{{html body}}{html:body}
\xmlsetsetup{#1}{p}{html:p}
\stopxmlsetups
\startxmlsetups html:flush
\xmlflush{#1}
\stopxmlsetups
\startluacode
function xml.functions.parseScript(s)
local mimetype = s and s.at and s.at.type
if mimetype and mimetype == "text/vnd.context" then
lxml.context(s)
end
end
function xml.functions.flushBody(b)
local xmlsetups = b and b.at and b.at["data-xmlsetups"]
if xmlsetups then
lxml.tobuffer(b, ".", "body")
context("\\typebuffer[body]")
context.xmlprocessbuffer("body", "body", xmlsetups)
else
lxml.flush(b)
end
end
\stopluacode
\startxmlsetups html:script:context
\xmlfunction{#1}{parseScript}

Re: [NTG-context] How to make \def accept block or buffer as part of (long) command argument
Uff, this is indeed deep tex. Thanks a lot for the example, Hans! I still need
to learn a lot.
After a walk and a bit of fresh air, I found another (much easier) way around
my problem. This works since I don't need to deal with #2 in any special way:
\tolerant\def\startMyCommand[#1]%
{
\startallbeautifulcontextcommands
% whatever #1 does
}
\tolerant\def\stopMyCommand%
{
\stopallbeautifulcontextcommands
}
Then one can do in the main files:
\startMyCommand
\beginMyBuffer
bla bla
\endMyBuffer
\stopMycommand

[NTG-context] Blank lines discarded when \typing
Note the presence of double-spaced blank lines in the following document
and in the attached source file:
\setuptyping[numbering=line]
\starttext
\startbuffer[javacode]
try {
final var num = stack.pop();
if( num != null ) {
stack.push( blah );
}
return true;
}
\stopbuffer
\type{\typebuffer}:
\typebuffer[javacode]
\type{\typing}:
\starttyping
try {
final var num = stack.pop();
if( num != null ) {
stack.push( blah );
}
return true;
}
\stoptyping
\type{\typefile}:
\typefile{t.java}
\stoptext
There appear to be two issues.
First, \typefile produces what I'd consider the "correct" result, where the
double-spaced lines appear on the page as a double-space. Both the
\typebuffer and \typing commands ignore double-spacing. The double-spacing
is also ignored by \xmldisplayverbatim. How would you configure to give
\typebuffer, \typing, and \xmldisplayverbatim to honour double-spaces the
same way as \typefile?
Second, of lesser importance, is that the blank lines aren't numbered. This
makes the line numbers inconsistent with respect to IDEs. How would you
label all blank lines as well?
Out of curiosity, does the second issue relate to the first?
Thank you!
try {
final var num = stack.pop();
if( num != null ) {
stack.push( blah );
}
return true;

[NTG-context] io.loaddata() or buffer.assigns()
Hi everybody
Are there any type of files that is required by io.loaddata or/and
buffers.assign ?
The following code works pretty well if there is no compilation problem by g++.
But it fails, i.e. \typebuffer[Mybuffer], does not produce anything if g++
fails (due to some errors in the cpp)
I have checked that err.cpp is well and truly created when g++ fails.
\startluacode
io.savedata("complx.h",buffers.getcontent("MyBuffer1"))
io.savedata("complx.cpp",buffers.getcontent("MyBuffer2"))
io.savedata("testcomplx.cpp",buffers.getcontent("MyBuffer3"))

Re: [NTG-context] getting line numbers
Thank you Hans. For what I had in mind (compiling some c++ inside a tex file) it seems to work. Anyway for this I am currently using the buffer and typebuffer solution you provide. T.

By the way, just for fun , is there a(n easy) way to get the linenumber
in the tex file ?
Thanks

Behind the scenes, it works by saving the content in an external file and then
running it through any external program. It also allows for caching the
result, and has many options for customizing the behavior.

Hi everybody
Is there a way to have an automatic access to the current line number of a
specific place inside a tex file ? To be more precise, here is what I would
like to do.
I am currently trying to have some automatic external compilation by g++ of
some portion of my tex file as in the following example below. \startC \stopC
defines a framed part of text written between lines 538 and 549. Of course, if
I add something before or inbetween my framed code, 538 and/or 549 will change.
Thus I would like to get these two numbers automatically.
Thank you.

[NTG-context] new font trickery
Hi,
I finally decided to start an experiment that I had on my todo list for
a while: dynamically scaling fonts. Below is an example of usage (plus
some comment). In that example some 2*200 different font sizes are used
which in mkiv demands 400 font definitions. This costs time and memory.
The example below runs (on my old laptop) in less than 2 seconds and
only uses two instances. I bet that our CJK users will love it.
I post it because:
(1) I need to discuss the impact with Wolfgang ... how do we integrate
this. We can for instance define some sizes (\tfa \tfb ...) differently.
(2) I want to see if average performance improves on huge documents with
many fonts / sizes (that is for Massimiliano to test).
(3) Are there side effects? It does work for math (rather neat trickery)
but maybe we need an additional configration for that.
(4) I considered several variants but for now use a low level
\glyphscale command that takes a number (in goodl old tex tradition a
scale of 1.0 is entered as 1000).
(5) The implementation can be improved a bit (performance wise). There
is a bit more overhead involved but usually I can compensate that.
(6) It will not be backported to MKIV so one can only test in LMTX.
it's a bit of a mix between engine and context features.
(7) There can be bugs (unforseen side effects, or typos in the somewhat
quick patches in the source).
Consider it an experiment, but so far I'm rather satisfied,
Hans

\title{Scaled fonts}
Although \CONTEXT\ is quite efficient with fonts there is always room for
improvement. However, after years of finetuning the font mechanisms
there was not
that much room left. This made me think of a different approach to scaling.
Nowadays fonts seldom come in design sizes. Also, in \CONTEXT\ \MKIV\ and
therefore \LMTX\ we always had so called dynamic features: apply additional
features locally, although that comes with a small penalty in
performance, it
saves additional font instances. It is a good approach for the
occasional small
stretch of glyphs, like small capped logos and such.
We now can also do dynamic font scaling, which means that we don't need
to define
a new font instance when the same feature set is used. Or course in
addition to
this features one can still use the dynamic features. This means that for
instance chapter titling can use the bodyfont instance and just apply
additional
scaling. Although for a normal run the number of loaded fonts is
normally small,
and the number of instances also isn't that impressive it can happen in
a large
document that you end up with a few dozen. That number can now be
reduced to half
a dozen.
Of course there can be side effects, whcich is why it's currently tagged as
experimental. There is also a small performance hit because we now need
to track
it but that is gained back because we load less fonts and have less
glyph runs.
It even works in math, although there some different trickery is needed.

Re: [NTG-context] Setting and measuring boxes TeX/Lua
Hello again, Hans!

Diving into functions and using context.stepwise() worked, until I've got
to: /cldf-stp.lua:48: bad argument #1 to 'resume' (thread expected) and
other errors. It was triar/error approach, not exactly knowing how
context.stepwise() works, and I was some more lua functions and iterations
before needing expansion.
Therefore I've changed the strategy (cannot give up):
- Create named buffers with formatted content (and store measures)
before they are needed.
- When needed, use the reference to the buffer.
Tests looked promising. After \starttext buffers and measures are known
(both TeX & Lua). Also tested in functions, etc.
But inside the first \xmlsetup, they are not expanded anymore, they are
typeset (like \typebuffer).
- How to have them expanded in \xmlsetup?
- Is other mechanism better suited for storing typeset blocks than
buffers (and will survive \xmlsetup)?
- If none of them is possible, what are the *other **cheats *then?

Re: [NTG-context] lmtx
Hi, Hans. The last release is considerably faster for smaller documents
(for larger documents differences seem to be neglectable). Thank you for
such an improvement. However, something is wrong with one manual:
luametatex manual won't compile:
156 Beware: the values are always saved in the format, independent of
the setting
157 of \prm {savinghyphcodes} at the moment the format is dumped.
158
159 A boundary node normally would mark the end of a word which
interferes with for
160 instance discretionary injection. For this you can use the \prm
{wordboundary}
161 as a trigger. Here are a few examples of usage:
162
163 \startbuffer
164 discrete---discrete
165 \stopbuffer
166 >> \typebuffer \startnarrower \dontcomplain \hsize 1pt \getbuffer \par

A number should have been here; I inserted '0'. (If you can't figure out
why I
needed to see a number, look up 'weird error' in the index to The TeXbook.)
The prepackaged PDF manual is also broken: an error banner.

Jairo :)

Hello list,
is there a better way to interlace overbraces and underbraces like this?

These are the expressions to combine:
$$\overbrace{a+b+c}+d \quad a+\underbrace{b+c+d}$$
This is the desired result:
$$\overbrace{a+b+c}+d \kern-16mm\underbrace{\hbox to 15mm{ }}$$

Hi,
I read the new manual with a great joy! This is really nice improvements of
MetaFun! I also like the 3D plots!
I had the possibility to try out some contour graphics on a freshly updated
system. I have two questions:
1) I think the first (blue) plot looks fine and it looks like it could be
the same curve as the blue one in the Mathematica plot (page 3). Why does
my second example (orange) not match with the result from Mathematica
(orange)? (I think I do something wrong)
2) Is there a way to combine the two contour plots in one MetaFun drawing?
If I add them both to the same, only the last one shows. If I try
functions={"-4+x^2+x^5+15*y-y^2-10*x^3*y^2+5*x*y^4","-15*x+2*x*y+5*x^4*y-10*x^2*y^3+y^5"}
it does not show both either.

Hi Sanjoy,
when you have a equal number of questions ans answers you can create a
enumeration for each and collect the answers with the block mechanism.
At the end of the document you can flush the collected answers.

[NTG-context] Problems with setups module
Hi everyone.
The following code gives different results by commenting and decommending

Could it be a problem with the setups module?

Re: [NTG-context] Which commands to use to show setups?
Hi Tommaso,
\startttyping is a generated command (\definetyping[typing]) and to show
the command with \showdefinition you have to use
\showdefinition [starttyping:instance:typing]
or
\showdefinition [starttyping:instance:argument:typing]
A complete list with all arguments can be found in setup-mapping-en.pdf.
The output of \definition is wrong because there is a wrong check for
the number
of arguments for the command (because you can pass a list of commands).
The \showdefinition command needs also a small change because when you
use a instance (e.g. \showdefinition [starttyping:instance:typing]) the
caption
shows the passed argument (e.g. Definition 1 \starttyping:instance:typing)
and not the correct command (e.g. Definition 1 \starttyping).

Tommaso Gordini schrieb am 21.11.18 um 22:30:
Hello everyone!
This is my first message here.
I'm trying to write a ConTeXt guide in Italian.
The LaTeX *tcolorbox* package defines an environment dedicated to
LaTeX examples: above (or on the left) the source is written, and
below (or on the right) the typeset result.
Is there something similar for ConTeXt? Does it make sense, in your
opinion, to showing examples of source code with the related outputs
in this way?
There is no environment which produces the same output as the mentioned
package
you can use buffers for your examples in the document.
\starttext
\startbuffer
\startframedtext
\samplefile{klein}
\stopframedtext
\stopbuffer
\typebuffer[option=tex]
\getbuffer
\stoptext
You can use this to write your own environment for the examples (or use
the userdata
environment when you’re lazy :)
\defineuserdata [example] [alternative=example]
\defineuserdataalternative [example] [renderingsetup=userdata:example]
\startsetups [userdata:example]
\startembeddedxtable

Re: [NTG-context] Including part of a program source file
The verbatim commands have a range key which let you select parts of the
code,
you can use line numbers to include a small block (e.g. range={3,10} or
range {3,+7})
or you put labels in your code.
\startbuffer

\define\FirstCommand
{\dosingleempty\doFirstCommand}
\def\doFirstCommand[#1]%
{This is the definition for the first command}
% cmd:one:end
% cmd:two:begin
\define\SecondCommand
{\dosingleempty\doSecondCommand}
\def\doSecondCommand[#1]%
{This is the definition for the second command}

I am writing some notes using ConTeXt, which involves displaying parts
of some program source files. At present, I am manually cutting and
pasting the parts into the ConTeXt file. Is it possible to make ConTeXt
do that for me? I am thinking of including each part of the Coq sources
between tags like this:
$ cat src-file
part_to_be_included_1
part_to_be_included_2
I would like to say something like
\IncludePart{src-file}{tag-1}
in my ConTeXt file to get
part_to_be_included_1
at that place in the PDF output after I run `context'. I would
appreciate any advice on how to go about this.
Thanks,
Raghu.

Does what you want but of course it's sort of ugly for a module to do that.
What we can do is this which is still ugly but picking up verbatim is
always ugly:
\def\buff_start_indeed#1#2#3#4%
{\edef\p_strip{\namedbufferparameter{#1}\c!strip}%
\normalexpanded{\buff_pickup{#2}{#3}{#4}{}{\buff_stop{#4}}\ifx\p_strip\v!no\zerocount\else\plusone\fi}}
\protect
I want this to be configurable at runtime and the vim module already has code
that enables `strip=yes` and `strip=no` options (I do this via a function in
vim so that it works with both mkii and mkiv; although I don't think that
anyone uses the mkii module any longer).
I added `strip=yes` option to the filter module, which is now the default
option. See "Stripping leading whitespace" in the module documentation
(https://github.com/adityam/filter). This is a MkIV only feature and I
will not implement it in MkII.
I also made `strip=yes` to be the default in t-vim (to be consistent with
t-filter). In t-vim, the `strip` option works with both mkii and mkiv.

This is why only adapting both \xmlprettyprinttext and
\xmlinlineprettyprint gets the fuctionality for the other two commands.
The commands are invoked in this way:
\xmlinlineprettyprinttext{#1}{tex}
\xmlprettyprinttext{#1}{lua}
Maybe adapting \prettyprintbuffer and \inlineprettyprintbuffer to the
t-vim module works fine. (But this code is all Greek to me.)

Can you post a minimal working example. I don't use XML so it is difficult
for me to understand how these commands are used in practice.

\typebuffer[CodeExample][option=tex] doesn’t do anything,
but \typeCodeExample[option=tex] actually works, I didn’t expect that.

Re: [NTG-context] (again) \typebufferinline for XML inline code

Hans,
sorry for asking for this again, but I really need it to write some
documents about ConTeXt.
I have the following sample:
\startTEXpage[offset=1em]
only \type{a
b
c} one line
\stopTEXpage
\stoptext
\type
Would it be possible to have a new \typebufferinline that behaves such
as \type above (and has the same options in \setuptype)?
The most important part isn’t the suppression of line breaks inside, but
avoiding the addition of line breaks after and before the typed buffer.
I have been reading buff-ver.mkiv, but I’m afraid I cannot contribute
such a patch.
This is essential to have \xmlprettyprintinline and
\xmlprettyprintinlinetext in order to handle inline code in XML.

I guess I never heard of or forgot about \placesidebyside as well as

Therefore, if I’d like to simplify my code, but this doesn’t work:

You can't do that with buffers. If you need to define your own macros that
behave like buffers, you need to use \grabbufferdata (see buff-ini.mkiv).
But in this case, there is a simpler solution:
\defineframed
[CodeExampleFramed]
[
frame=off,
width=0.5\textwidth,
align=normal,
]
\definebuffer
[CodeExample]
\define\stopCodeExample
{\placesidebyside
{\CodeExampleFramed{\typeCodeExample}}
{\CodeExampleFramed{\getCodeExample}}}
\starttext

Even with some expansion, I get an infinite loop:
\starttext
\setuptyping[TEX][escape=yes]
\def\CodeExample#1{%

\stopTEX

no, because order matters

0xFFFC is just the same as "anything other than glyph or discretionary"

Replying to my own question, a fast fix (although far from perfect)
would be using xtables:
\def\replacesidebyside#1{%
\blank\startembeddedxtable[frame=off, option=stretch]
\startxrow
\startxcell\typebuffer[#1][option=TEX]\stopxcell
\startxcell\getbuffer[setups, #1]\stopxcell
\stopxrow
\stopembeddedxtable\blank}
\def\replaceontopofeachother#1{%
\blank\startembeddedxtable[frame=off, option=stretch]
\startxrow
\startxcell\typebuffer[#1][option=TEX]\stopxcell
\stopxrow
\startxrow[toffset=1em, split=yes]
\startxcell\getbuffer[setups, #1]\stopxcell
\stopxrow
\stopembeddedxtable\blank}
\starttext
\startbuffer[example-1]
\setupexternalfigures[location=default]
\starttext
\ConTeXt\ is awesome!
\externalfigure[cow.pdf][scale=250]
\stoptext
\stopbuffer
Frames won’t be split accross pages. There may be other issues, but none
tham I’m aware of ;-).
Just in case it helps,
Pablo

Many thanks for your suggestion, Aditya.
I’m afraid everything is forced to be in horizontal mode:
\starttext
\startbuffer[example-1]
\setupexternalfigures[location=default]
\starttext
\ConTeXt\ is awesome!
\externalfigure[cow.pdf][scale=250]
\stoptext
\stopbuffer
\placesidebyside
{\typebuffer[example-1]}
{\getbuffer[setups, example-1]}
\stoptext
\placeontopofeachother has the same feature.
This causes that \placefigure cannot be used.
Is there now hay to avoid the forced horizontal mode on both sides?
Many thanks for your help,
Pablo
