Re: [NTG-context] page[no] not working?
Hi Wolfgang,
As you don't provide a example with a description where you have the problem
I can't make a test but this could work in MkIV
I reckoned that the \page[no] command by itself was already broken, so I first
want to fix that before making things more complicated (like doing stuff with
before= or inbetween=).
\setupdescriptions[...][inbetween={\blank[samepage,line]}]
This isn't exactly what I need, since the page break occurs between the header
and the body of the description (the boxed block is inside the description).
Or is inbetween exactly where that should end up?
However, using your \blank command directly does work. I've now put it in the
before= of my typing environment and that works as well. Thanks for this!
However, I'm still surprised that the \page[no] command, which is documented
to supress page breaks, does not do anything, while I need to insert some
magical blank as well. Should \page[no] be documented as broken?

Re: [NTG-context] page[no] not working?
Hi Wolfgang, \page[no] did work but only when you use it in the correct way. snip exapmles Aha, page[no] only works directly after a paragraph break. I haven't seen that documented anywhere. I'll put it up on the \page reference page. Is only after a paragraph break the right usage instructions, or is it more complicated than that? As you're unwilling to show a example I can't give a concrete answer. I showed a reduced example, which showed the problem I was having exactly. I could have sent you my entire document consisting of many files, but that wouldn't be too useful I guess. I appreciate your attempts to provide a complete solution for my entire problem, but I have enough clue to fit in a working \page[no] into the right setup commands, if only I had a working \page[no] command :-) Fortunately, you've now provided me with two working commands (\par\page[no] and \blank[samepage,line]), so I managed to make my document look pretty! If you could only answer my first question above, then I'll improve the \page documentation. Thanks!

Re: [NTG-context] Selectively not using a font feature
Hi Hans,
it assumes that you know what is provided by the font ... you cam
play with addff and subff and addfs and subfs (individual features
cq. current set)
I couldn't get the addff/subff stuff working to remove the font feature, but
the following did the trick:
\definefontfeature[default][default][onum=yes]
\definefontfeature[normalnum][default][onum=no]
And in the text use: {\definedfont[Serif*normalnum]0 to 7}
Thanks,

[NTG-context] page[no] not working?
Hi all,
I've come to understand taht using the \page[no] command should prevent a
pagebreak at that particular spot whenever possible. However, this seems to be
not working for me. My actual problem is with a \startframed directly after a
description header, but the problem is easily reproduced with the below
example (for MkII, replace the 25cm with 20cm). The \dontleavehmod was needed
to make the \blank work...
\starttext
\dontleavehmode
\blank[25cm]
A
\page[no]
\startframedtext
H
\stopframedtext
\stoptext
This example generates the A at the bottom of the first page, with the boxed
H on the next page, putting a page break exactly where the page[no] is. Is it
broken, or am I missing an important detail about how page[no] works?
I've also tried
\defineblankmethod [nobreak] {\nobreak}
\blank[nobreak,line]
and some variations as suggested by Wolfgang (IIRC) in some thread from 2008,
but that failed with missing number, treated as zero for me.

Re: [NTG-context] Biblography list does not show numbers
Hi Taco, I have assumed that ConTeXt has more authors that need APA like citations than bracketed numbers. ConTeXt has never had a very strong presence in the exact sciences. If that's the case, then the \cite command does the wrong thing by default, since it generates references as bracketed numbers. My complaint was not one of default style, but of inconsistency: \cite uses bracketed numbers, while the list of references just uses author names and years (which I now understand to be APA style. This also means that this is a MkIV problem, my example did generate (author, year) style references with MkII. Gr.

[NTG-context] Biblography list does not show numbers
Hey all,
I'm trying to use a bibliography, but it seems no numbers are show in the
biblography that is generated. The following example:
Test.tex:
=
\usemodule[bib]
\setupbibtex[database=Test]
\starttext
\section{foo}
Blaa \cite[foo] Bar
\completepublications
\stoptext
Test.bib:
==
@article{foo,
author = {Bar},
title = {Foo},
year = {2009},
}
generates the following text:
1 foo
Blaa [1] Bar
1 References
Bar (2009). Foo. .
So, the citation gets a number as it should, is referenced by the number, but
the list of references does not list that number. This makes the bibliography
pretty useless :-) This also happens with MkII (though the reference doesn't
get a number, but uses the author name and year: (Bar, 2009).
Am I missing something, or is this a bug?
On a related note, if I remove the \section, no reference will be generated.
This is probably not a problem in real documents, though.

Re: [NTG-context] inothermargin overlaps
Try
\starttext
Foo Baz \inmargin {Blerf \\ Baz}
\stoptext
Hmm, that might work, but my real case is slightly more complicated. I have
the \inmargin wrapped in a \refdef command, that references some topic on some
page. So I say \refdef{foo} and it looks up both the text and page number for
foo and puts that into the margin.
I could probably complicate my \refdef command into taking multiple references
at the same time. However, that will still require me to merge those commands
when they are close together, which might mean some of the rerefences are not
in their logical place anymore. For example:
Some short paragraph referencing foo. \refdef{foo}
And another paragraph refering bar. \refdef{bar}
This has the references in the logical places. With your suggestions, I must
change this to:
Some short paragraph referencing foo. \refdef{foo,bar}
And another paragraph refering bar.
Which is more error prone when I start moving around text... So, it's a
workable solution, but it's not quite ideal yet...

Re: [NTG-context] How to not gobble space after a command
Hi Luigi,
forget my last post. I was in a hurry last week and put a
\def\autoinsertnextspace{}
in my document just to get it compiling on context 2009.11.24. If I remove
that, it stops working with texexec --lua (as well as just context) with
the same undefined control sequence error. It still works with just texexec
(e.g., with MkII).
So, it works for me with 2009.10.28, and gives errors with 2009.11.24. There
is no version where it silently fails, that was my own fault :-)
Actually, it does in fact seem the macro has completely disappeared. With the
old version:
/usr/share/texmf/tex/context/base$ grep def.autoinsertnextspace *
spac-gen.mkii:\def\autoinsertnextspace{\futurelet\nexttoken\doautoinsertnextspace}
spac-hor.mkiv:\def\autoinsertnextspace{\futurelet\nexttoken\doautoinsertnextspace}
With the new version:
/usr/share/texmf/tex/context/base$ grep def.autoinsertnextspace *
spac-gen.mkii:\def\autoinsertnextspace{\futurelet\nexttoken\doautoinsertnextspace}
The comment in the old version does say:
%D This is a dangerous feature because it makes the \TEX\ source
%D less portable, i.e. any parser now needs to apply exactly the
%D same algorithm when it wants to interpret the source. We
%D strongly recommend not to mention this feature in manuals! It's
%D provided for users who are hooked to such a mechanism.
So perhaps this is removed intentionally? Perhaps Hans can comment?

[NTG-context] How to not gobble space after a command
Hi all,
I'm working with a few custom macros to simplify typing a bit, like:
\def\VHDL{\small{VHDL}}
However, when I use this macro in text, like \VHDL this, it gobbles the space
after it. I've seen some references that say to solve this by writing \VHDL{}
instead, but that is of course very unpretty. I've tried to put all kinds of
stuff ({}, \mbox{}, \obeyedspace, etc.) inside the \VHDL macro, but it seems
the space is already gone there, so that didn't work. (Note that just putting
a space inside the macro won't work, for cases where I use \VHDL, like this)
It seems that latex has an xspace package that does some guesswork about
whether a space is required, but it looks mightily scary. Does ConTeXt provide
for any way to solve this problem in a nice way? Or is this just so
fundamental in TeX that there is no real solution?

Re: [NTG-context] Getting the width of an expression inside lua
Hi Hans,
thanks for the instant reply :-) I haven't tried your suggestion yet, but I've
got a few questions first.
\startluacode

Would there be any danger of overwriting an existing box by doing this? I'm
not quite sure how this boxing thing works...
tex.sprint(\\ctxlua{document.step_two(0)})
I guess this indirection is needed to force the \setbox command to be
expanded? I guess tex.sprint doesn't expand its arguments immediately, so just
putting document.step_two(0) instead of the entire tex.sprint(\\ctxlua...
won't work...
I'm using this from inside a pretty printer, so I'd have to think a bit about
how to set this up so things run inside the right context and stuff, but I
guess that should work out. Still slightly more complicated that a direct How
wide is this thing function, though.
function document.step_two(n)
tex.sprint(width: ,tex.wd[0])
end
I gues you mean tex.wd[n] here, but whatever :-)
\ctxlua{document.step_one(test {\\bf test} test)}
\box0
Why is this \box0 needed? Just to show the test test test output? AFAICS, the
width of the box will be displayed always, even without this?

context says it has a font that is not found. However, a bit further down,
this crashes.
The cause of this is that the nullfont is returned as defined in
font-ini.lua, not just nil:
fonts.ids[0] = { -- nullfont
characters = { },
descriptions = { },
}
This font has no name, but math-vfu.lua uses fs.name unconditionally. Either
math-vfu.lua should be fixed to test for this, or a line should be added to
the null font above:
name = ,
I've tested the latter, and it solves my immediate problem.

Re: [NTG-context] obscure luatex error
Hi,
luatex: ../../../source/texk/web2c/luatexdir/tex/printing.c:266: print:
Assertion `c 256' failed.
[329.327MTXrun | fatal error, no return code, message: luatex: execution
interrupted
A quick glance at the code, shows it's in the following part:
/*
An entire string is output by calling |print|. Note that if we are outputting
the single standard ASCII character \.c, we could call |print(c)|, since
|c=99| is the number of a single-character string, as explained above. But
|print_char(c)| is quicker, so \TeX\ goes directly to the |print_char|
routine when it knows that this is safe. (The present implementation
assumes that it is always safe to print a visible ASCII character.)
@^system dependencies@
The first 256 entries above the 17th unicode plane are used for a
special trick: when \TeX\ has to print items in that range, it will
instead print the character that results from substracting 0x11
from that value. This allows byte-oriented output to things like
\.{\\specials} and \.{\\pdfliterals}. Todo: Perhaps it would be useful
to do the same substraction while typesetting.
*/
void print(integer s)
{ /* prints string |s| */
...
} else if (s = 0x11) {
int c = s - 0x11;
assert(c 256);
print_char(c);
} else {
...
}
It seems the second comment block talks about the code in which the error
occurs. It also seems that this is either caused by some very high unicode
character that's printed, or some invalid (uninitialized?) value is passed to
print().
Do you think you could compile luatex with CFLAGS=-g, and run it in gdb to get
a backtrace? That might help to see where this comes from...

[NTG-context] \setupquotation affecting \quote
Hi,
I've been trying to use \setupquotation, but it seems it doesn't just affect
\quotation, but also \quote. In particular, setting style to tfb enlarges the
font used by \quote and somehow removes the quotes from around it.
Seeing that there is also a \setupquote, and from looking at the code, I think
this is not supposed to happen. This happens with MkII as well as MkIV, it
seems.
The following example shows the problem:

[NTG-context] Passing variables into context
Hi all,
I've been trying to make a metapost graphic, based on the \textwidth. However,
it seems I can't just pass in \textwidth as an option. For example, the
following breaks:
\startuniqueMPgraphic{HLine}
draw origin -- (\MPvar{width}, 0mm);
\stopuniqueMPgraphic
\starttext
\setupMPvariables[HLine][width=\textwidth]
\uniqueMPgraphic{HLine}
\stoptext
with the following error:
mplib | mp terminal: textwidth
! Undefined x coordinate has been replaced by 0.
to be read again
;
* ...d:=3441; draw origin -- (\textwidth , 0mm);
It seems that the \textwidth option is not expanded before being passed to MP.
Is there any way to force this expansion? I've tried \expandafter (without
really understanding what that does), but that didn't help.
I've tried putting this graphic as an overlay under an \framed, which allows
me to use the \overlaywidth macro in metapost (which I assume is expanded
specially by context?). This worked, but is not very elegant. Is there
something more straightforward possible?

Hi Taco, You should try \the\textwidth Thanks, that works. Could you enlighten me as to what \the does and why this helps?

[NTG-context] vardef with @# not working within context
Hi all, I've been fiddling around with metaobj a bit, but defining my own objects failed. After some debugging, I've reduced this to a metapost / context MkIV issue (so no metaobj specifics anymore). What happens, is that vardefs that use @# as a placeholder in their name only work when they are defined in an external .mp file. When I define them inside context (\startMPcode or \startMPinclusions), I get funny errors (mostly Isolated expression, which seems to mean that the macro is not defined). I suspect this is because the way context extracts metapost code. Is this a fundamental problem, or could it be fixed? The following context file will easily reproduce the problem: \starttext \startMPcode vardef foo = draw (0mm,0mm)--(10mm,10mm); enddef; foo; vardef x...@# = (@#,@#) enddef ; draw xy0mm -- xy10mm; \stopMPcode \stoptext Running this file gives the following (first) error: mplib | mp terminal: xy0mm ! Improper `addto'. To illustrate that this is specific to the use of @#, I've included the foo vardef which does work properly. When I move the vardef xy.. line to a separate file, say foo.mp, and replace it with input foo;, the errors disappear. Gr.

Re: [NTG-context] metaobj and luatex 0.42.0
Hi Matthew,
I've been playing with metaobj and luatex 0.43 for a bit, and faced similar
problems. Lots of stuff about redundant equations and other stuff I didn't
understand.
However, I've found that cleaning up your objects when you're done pretty much

makes it work for me:
\startMPinclusions
input metaobj;
\stopMPinclusions
\starttext
\startMPpage
newBox.a(\sometxt{hello world});
a.c = origin;
drawObj(a);
clearObj a;
\stopMPpage
\stoptext
I'm not completely sure why this is clearObj a (and not clearObj(a), which
seems to be more logical considering drawObj also takes parentheses), but
that's probably something of the wonderful world of macro programming.
Hope this helps,

[NTG-context] Using \startalign outside of math mode?
Hi, I'm using a custom pretty printer to apply some formatting to a buffer. However, I'm not using a monospaced font, but some sans serif font to display the result. In the original text, I have some lines that are nicely aligned using leading spaces. For example: foo = bar | baz Obviously, when using a non monospaced font for this, the alignment is lost. When in math mode, I can use \startalign to force alignment, like: \startalign foo \NC= bar \NC| baz \stopalgin However, I haven't manage to switch to math mode inside pretty printed text. Also, even if I would, I would get my text rendered in math mode, which probably won't work. So, I'm wondering if there is anything like \startalign to use outside of math mode? I've been looking at the implementation of \startalign, but couldn't find it... Some way to insert spacing until some fixed point (e.g. tab-stop like) would probably work, if I can define the tabstop on a case by case basis? Gr.

Re: [NTG-context] Using \startalign outside of math mode?
Hi all,
foo = bar
| baz
it seems I found some sort of a solution. Using the \setwidthof I found at
[1], I wrote the following:
\def\setwidthof#1\to#2%
{\bgroup
\setbox\scratchbox\hbox{#1}%
\expanded{\egroup\def\noexpand#2{\the\wd\scratchbox}}}
foo = bar
\setwidthof{foo }\to\alignwidth
\hskip\alignwidth| baz
This works, but is not so pretty, obviously. Since I'm using a custom pretty
printer, I can probably hack something up that generates this from the more
natural form automatically. Still, I'm wondering if there are more pretty
methods to do this. In particular, this method is completely limited to
indents at the start of a line (e.g., aligning the b's of bar and baz isn't
possible, though I could perhs do more complicated math using the width of
| , but that will become even more hideous...
Any other suggestions?

[NTG-context] Why are pretty printer names uppercased?
Hi all, according to the wiki, and the current code, the arguments to \installprettytype should be uppercased. E.g.: \installprettytype [PHP][PHP] Referring to them should be uppercased as well: \definetyping[PHP] [option=PHP] \setuptyping[option=PHP] However, the filename should be lowercase, e.g. pret-php.lua and the pretty printer should register itself in lowercase as well: buffers.newvisualizer(lua). The first thing that happens to the arguments of installprettytype is to lowercase them, and every option= argument that points to a pretty printer is lowercased by setvisualizer in lua before being used. If everything is lowercased, why do we still recommend the arguments to \installprettytype and option= to be uppercase? IMHO this makes things confusing when trying to understand which PHP refers to which php or PHP in the greater picture of things. Why not recommend people to use lowercase identifiers instead, since we're changing everything into lowercase anyway? Or perhaps go a bit further and remove the lowercasing code alltogether, since I don't see any real gain. If the strings / filenames should just match exactly, things will get a lot more predictable?

Re: [NTG-context] Why are pretty printer names uppercased?
Hi Hans, according to the wiki, and the current code, the arguments to \installprettytype should be uppercased. E.g.: \installprettytype [PHP][PHP] because want uppercase \startTEX \stopTEX Well, those would be coming from the first argument of definetyping. AFAIU, neither argument to installprettytype is related to these commands. \definetyping[PHP] [option=PHP] indeed. as i don't like casing in filenames, and function names Agreed, me neither. actually, the advice is that user definitions use uppercase \definehead[MySection][section] etc, just to avoid clashes with built in commands That makes sense for commands, which is not what I'm proposing to change. I would propose making it look like the following: \installprettytype [php][php] \definetyping [PHP][option=php] Here, the second php refers to pret-php.lua, the first and last php refer to each other and to the php in newvisualizer(php). The command defined is still \startPHP, but now the values that refer to other lowercase things (filename, pretty printer name) are lowercase consistently. How's this? Gr.

Re: [NTG-context] git repository
Hi Patrick, I don't know if you have noticed that the git repository has been replaced by a newer one. I'm surprised that there is even a git repository at all. On the wiki and all documents I've seen so far, there is only talk about rsyncing from an ftp, git is never mentioned. However, looking at the contents of the git repository, it seems that this is just a repository that automatically checks the files from the ftp every so often? I was hoping for an actual git repository with commit messages to show changes, but it seems the git repository isn't the primary version of context (I guess Hans' local copy is)? Gr.

Re: [NTG-context] git repository
well, such messages would not help much unless they would be detailed (and then should be done for each file); as i work on all files at the same time it would cost me way to much time and it gains me nothing; looking at the diff in a git gui is more informative A git commit contains changes to multiple files, with a single message, so if you work on one logical change at a time, this should not be a problem. Perhaps you are thinking of CVS, which (AFAIK) provides only per-file versioning? Also, even short messages like, Added \foo command, or Fixed \bar alignment would probably be helpful. Then again, you are completely correct that there is some effort to be invested to properly use a versioning system, especially if you're not used to working with one. In my experience, having a versioning system like git (or mercurial seems to be good as well) does pay off in the long run, but only if you tune your development flow to work well with it. Gr.

Hi Peter Khaled, I think there is a way to use ConTeXt commands inside verbatim environments, but I don't recall it. I think this is the option=commands option for setuptyping friends.

Im not exactly sure what you're trying to achieve, but perhaps you could do

done, something with whitespace I think.

[NTG-context] [PATCH] Add begin_of_buffer and end_of_buffer hooks for lua pretty printers
Hi all, while working on a custom pretty printer, I was having the need to keep some state variables for the duration of one buffer, and reset them again for the next buffer. With the current hooks a pretty printer has available, this is not possible, since you never know what the first and last lines are. The attached patch adds two new hooks, begin_of_buffer and end_of_buffer, which will be called when typing a buffer or a file (e.g. \typebuffer or \typefile). They are not called for typing a phrase (e.g. \type). Is this patch acceptable for inclusion? Gr.

[NTG-context] Limited with rule?
Hi all,
I've been trying to create a horizontal rule of limited width, using MkIV. My
best approach so far is using a \framed with only a bottom frame:
\framed[frame=off,bottomframe=on,width=.5\textwidth]{}
However, this is not quite elegant. Context provides two commands for drawing
lines, \hairline and \thinrule (which seem to do the same from looking at
their definition in pack-rul.mkiv, though \hairline does not seem to respond
to \setupthinrules for some reason I cannot discern...).
However, \setupthinrules accepts a lot of options (including height and depth,
which get passed to \hrule, but there is no width option (nor does there seem
any way to get \thinrule to pass a width to \hrule).
Another attempt to put a frameless \framed around the \hairline (which gets as
wide as the containing box) failed as well. The line kept getting vertical,
even when I sprinkeled some \dontleavehmod or \pars around...
Any suggestions on how to do this?

Re: [NTG-context] \typebuffer with typing style
Hi Peter,
\setuptyping[option=TEX]
This is what I am using now, but this changes the global settings and requires
resetting them afterwards. Not so pretty. I was hoping for a better method to
achieve this, but I'm starting to doubt there is one currently.
I've been trying to give \typebuffer a second argument with options or a
typing style, but I haven't been so succesful so far...
However, from looking at the definition of \dotypebuffer makes me wonder a bit
if my understanding of TeX macros is faulty, or the code is weird:
\def\dotypebuffer[#1][#2]%
{\iffirstargument
\dobuffer{17}{#1}\dotypefilebuffer
\else
\dobuffer{17}{#2}\dotypefilebuffer
\fi}
What I see here is the there is an argument 17 passed, which is not used by
\dobuffer at all. Also, why is this 17 ? Secondly, there is a use of #2 in
this definition, but only when there is no first argument (and thus, no second
argument either). Is this a leftover that could be replaced with {}, or am I
missing something?

Re: [NTG-context] \typebuffer with typing style
Hi all,
Snip question about styled \typebuffer
Shortly after sending my email, I realized the actual problem I was trying to
solve was not the one I posted, so perhaps I can clarify that a bit.
What I'm trying to do, is pass some text to a custom command, which should
then be displayed in a custom typing style. It seems I can pass some text to a
command fine, even multiple lines:
\define[1]\test{Lines: #1}
\test{
One line
Two lines
Three lines
}
However, this will obviously not give me any typing style at all, just a
single line with all the words after eachother. I can't just use \starttyping
(or \startFOO, which was the actual goal of all this) inside a \define, since
that gives me:
File ended while scanning use of \dododowithbuffer.
So, this made me look at using buffers, since I can pass in an entire buffer
and use \typebuffer to get it in a typing style. However, as mentioned before
I can't seem to be able to pass an actual style to \typebuffer (one defined
with \definetyping).
The only way I've found just now, is to use \setuptyping. However, that takes
effect for the rest of the document, so I have to reset the settings to their
defaults afterwards, destroying any custom settings that could have been set.
I can't seem to find a way to push the typing settings or save them somehow,
so this is not quite a perfect solution...
Any other suggestions?

[NTG-context] Verbatim / prettyprinting in mkIV
Hi all,
I've been struggling with verbatim printing in MkIV for a while now and found
some confusing things. I did finally get things working, but after quite some
effort. I'd like to hear if my conclusions are correct, perhaps I can put them
on the wiki then.
I was trying to set up some custom pretty printing scripts, using lua (since
I'd rather not learn complete tex scripting :-p). Looking at the files in
/usr/share/texmf/tex/context/base and the wiki (Verbatim_text talks about
verb-foo.tex files), I created a file called verb-foo.lua. I put this beside
my document at first, and then in /usr/share/texmf/tex/context/base when it
did not work, but neither worked. I tried setting things up as follows:
\installprettytype [FOO] [FOO]
\definetyping[FOO][option=FOO]
\startFOO
blub
\stopFOO
Trying to trace the code, I worked out things should work as follows:
\installprettytype sets the evalue \??ty\??tyFOO to point at FOO
\definetyping call \setupprettiesintypeFOO, which finds looks up the above
evalue, finds FOO and then turns that into verb-foo and calls
\ctxloadluafile{verb-foo}{}. This sets up the buffers.visualizers.foo value in
lua. When actually starting a typing environment, dodotypeA or dodotypeD call
buffers.hooks.flush_line, which in turn calls
buffers.visualizers.foo.flush_line.
The above didn't happen for me, so I tried manually loading the lua file using
\ctxloadluafile{verb-foo}{}. After this, things started working for some reason.
When looking closer and installing some \writestatus lines in core-ver.mkiv, I
found that \setupprettiesintype was never actually called! Closer inspection
showed that the entire core-ver.mkiv is never loaded when running context
--make. However, there is a second file, buff-ver.mkiv which closely
resembles core-ver.mkiv and which is loaded. An important difference, however,
is that buff-ver loads pret-foo instead of verb-foo (or rather, uses the value
of \f!prettyprefix, which is set to pret- in mult-sys.tex).
Renaming my lua file to pret-foo.lua made context find it exactly as it
should, also when putting the file next to the main document.
So, my main question was, are the verb-*.lua and core-ver.text files still
used in any way? I just checked the minimals tree, and found out they have
been removed already (but I didn't have -d in my rsync commandline to actually
remove them). Looking at the previous version I was running (2009.05.20 beta)
it seems that this change was actually pretty recent, so I mostly created this
confusing situation by upgrading today (because my verbatim file was not
properly loaded). I'm not so sure why it was not working before then, but at
least it is working now.
Heh, this is what you get when you write an email while you are still trying
things out. All this buildup to get to a question, when the question is not
even relevant. As for another relevant question: Is my analysis of how things
are supposed to work correct? Then I might put something like it on the wiki.
Also, it seems that \ctxloadluafile does not give an error when the file was
not found. If it would have, things would probably have been a lot easier. Is
there any compelling reason to make it fail silently?

[NTG-context] \typebuffer with typing style
Hi, I'm trying to use a buffer together with a custom typing style using the latest beta with MkIV, but so far I've only managed to do this using \startFOO and \stopFOO inside the buffer: \definetyping[FOO][option=FOO] \startbuffer[bar] \startFOO baz \stopFOO \stopbuffer \getbuffer[bar] Since the \getbuffer is really inside some self-defined command, I'd like to put the startFOO / stopFOO in there as well. However, I can't seem to find a way to do this, since \startFOO \getbuffer[bar] \stopFOO gives me compile errors. It seems the canonical way to define typing and buffers is using \typebuffer, but that only seems to work with the default typing style. I'd like to do the following: \definetyping[FOO][option=FOO] \startbuffer[bar] baz \stopbuffer \typebuffer[FOO][bar] From looking at buff-ini.mkiv it seems typebuffer has some code to handle a second argument, but it seems to always throw it away (as far as I can understand this Tex stuff... :-). Is there some way to achieve this? Would it be good to make \typebuffer support this if there isn't? Gr.

Re: [NTG-context] \typebuffer with typing style
Hi all, since \startFOO \getbuffer[bar] \stopFOO gives me compile errors. Actually, that turned out to be my own typo. However, this doesn't give me what I want, but just a verbatim \getbuffer[bar]... Gr.

[NTG-context] KR itemize fails with latest beta
Hi, I've downloaded the beta today, which fails on one of my itemizes using the KR numbering scheme. I'm using MkIV context, with the following file: \starttext \startitemize[KR] \item Foo \stopitemize \stoptext When compiling this file, I get the below errors.
