it depends abit on what gets flushed, in those cases a low level flush
has to be used
\xmltext
\xmltextonly
\xmlraw
to get the raw data .. depends on content

Dear list,
In short, my question is: why does \wordright cause a line-break when the line
preceding it breaks with hyphenation and does not otherwise? How to avoid it
(if at all possible)?
I have this delimitedtext instance called 'amnata' defined as below:
\definemeasure[amnatamargin][3cm]
\definedelimitedtext
[amnata]
\setupdelimitedtext
[amnata]
[
left=,
right=,
leftmargin={\measure{amnatamargin}},
rightmargin={\measure{amnatamargin}},
]
I am using this to quote paragraph(s) of other authors.
Since, I also want to indicate where the quote is from, I use this as follows:
\startamnata
⋮
\wordright{author}
\stopamnata
so that the author's name appears at the right-edge of the block.
When the penultimate line inside the block breaks without hyphenation, then
argument of \wordright is typeset as expected (i.e. in the same line).
On the other hand, when the penultimate line inside this block breaks with
hyphenation, the argument of \wordright is pushed to the next line even when
there is enough space for it on the same line.
Here is a sample illustrating this:
\startamnata
A quote from another author : Suppose that thereisalongwordhere.
\wordright{– author}
\stopamnata
\startamnata
A quote from another author : Here, the text does not cause
hyphenation in the first line.
\wordright{– author}
\stopamnata
[I have attached the output here as an image]
How do I ensure that this does not happen, if that is possible at all? I
suppose this is expected behaviour but I am not able to understand why.
Thanks,
kauśika

Yes, the new \blackboard command works, so $\blackboard{Q}$ works. Thanks.
The \blackboard command is a switch like \it, to keep it local to a
single character put the left brace before the command.
$Q {\blackboard Q} Q$
also, it is an math alphabet switch (one of the math alphabets)

Hello,
On Thu Oct 21, 2021 at 8:04 PM CEST, Hans Hagen via ntg-context wrote:
I cleaned up some more backend code. There were some mails about dates
and such and although the date field in setupinteraction works ok a more
drastic overload is doen with directives. The reason is that the fact
that we can set the date (and traler) is only because it permits
generating pdf files that can be compared. No date as a bad idea anyway.
\setupinteraction[title=My Title]
% \enabledirectives[backend.date=2034-06-07]
\enabledirectives[backend.date=no]
\enabledirectives[backend.trailerid=no]
I checked the backend code and some of the related os functions. I put
together a patch that hopefully fixes some stuff and doesn't break
anything. The changes:
1) Dates parsed by ConTeXt (function converters.totime), such as those
that are input to backend.date, now allow specifying seconds and time
zone information. If there is no timezone the datetime is presumed to be
in local time, otherwise the datetime is offset by the local / specified
time zone difference (because ConTeXt outputs these dates as local times
with local timezone). Additionally both "T" and " " are now allowed as
date/time separator characters. Thus dates output by ConTeXt can be also
fed in.
i made the parser a bit more tolerant
"1234-12-30"
"1234/12/30"
"1234-12-30 23:45"
"1234-12-30 23:45:16"
"1234-12-30 23:45:16"
"1234-12-30T23:45:16+01:00"
"1234-12-30 23:45:16-02:00"
"1234-12-30 23:45:16+05:00"
"1234-12-30 23:45:16 05:00"
"1234-12-30 23:45:16 05:00"
(I'll send you the file to check/test)
2) Fix the os.timezone function. Previously, it could be wrong around
midnight, which I discovered only by chance. The trick is lifted from
http://lua-users.org/wiki/TimeZone, which I hope is OK. The before and
after (I am at +02:00):
os.localtime() 2021-10-22 01:44:24
os.now()2021-10-21 23:44:24
os.timezone(true) -22:00
os.localtime() 2021-10-22 01:46:23
os.now()2021-10-21 23:46:23
os.timezone(true) +02:00
shouldn't we also offer a -02:00 ? (relative)
I also extended the interface of os.timezone to accommodate 1), but as
this is probably a very public interface, I am not sure if these changes
are OK. If more changes to the interface can be made, I propose to get
rid of the delta parameter, since it seems like a remnant from the past.
maybe later, i need to check other files
Some caching can also be introduced, but I again wasn't sure if this
even would be the final form of the function, so didn't do anything in
that sense, yet.
i'll adapt it to that
3) Don't use %X in time formats. It is specified to be platform
dependent and we want %H:%M:%S everywhere. Also, it would be nice if
lpdf-xmp.lmt would use the os.fulltime() function to format dates (like
back-exp.lmt does), but there are multiple dates with different formats
and purposes and it is probably too late to change now.
(probably not that harmfull on the platforms we support)
the reason for different times is that i never liked the timezone in
regular date/time (so only the mandate one had it) but in the end i
don't care that much about times/date i never look at (i admit that i
never consult any of this pdf meta data)
4) I changed the os.fulltime function, that returns date + time + local
time zone to output the _local_ time instead of UTC time. This is AFAICT
the right way to do times. The PDF spec says:
If no UT information is specified, the relationship of the specified
time to UT shall be considered to be GMT. Regardless of whether the
time zone is specified, the rest of the date shall be specified in
local time.

I’m afraid that if rotation values are 270 or 180, the imposed page has
an extra vertical space before.

Many thanks for this fix too.
Sorry for insisting, but could you check what is wrong with an extra
blank space in rotated imposition
(https://mailman.ntg.nl/pipermail/ntg-context/2021/103909.html)?
.. it was not really a minimal example ...
\showframe
\starttext
\topskip4cm
\rotate[rotation=90]
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
\rotate[rotation=90]
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
\stoptext
so, you need to wrap it, like
\startpagemakeup \rotate[rotation=90]
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
\startpagemakeup
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup
\startpagemakeup \rotate[rotation=90]
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
\startpagemakeup
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup
and not make it 'sort of text that breaks or not across the page'. Now
it is an interesting question why ... (spoiler: nice animation:)
\starttext
\topskip4cm
\dostepwiserecurse{0}{360}{1}{
\rotate[rotation=#1]{\externalfigure[A3page.pdf][page=1,width=\textheight]}
}
\stoptext
so we probably cross some threshold with some angles and because these
are basically lines, we then get an interplay woth topskip, maxdepth etc
(which normally goes unnoticed)
the good news is that you can play with it because rotate is normally
configured for inline usage (so we get depth and height) you can use the
location parameter to do otherwise:
% normal default depth fit broad high middle
\starttext
\topskip4cm
\dostepwiserecurse{0}{360}{1}{
\ruledhbox{\rotate[rotation=#1,location=high]{\externalfigure[A3page.pdf][page=1,width=\textheight]}}
}
\stoptext
irr it's actually shown somewhere in a manual but the source also has this
% \dostepwiserecurse{0}{360}{10}
% {\startlinecorrection[blank]

It works very nicely. I played with the test file you sent me, and I
find that in the .lfg file, the up parameter set to 0.06 instead of

there are no ssty's for the quadruple prime in that font but if you need
primes so badly you probably shouldn't use it anyway i guess (there are
only super-textsize ssty variants for the 1/2/3 and their reverse)
anyway, as you desperately need these quads (why check otherwise),
adding this to the lfg blob helps:
local four = characters[0x2057]
if four then
local one = characters[okay]
local owd = .75*one.width
local off = .6*one.height
four.width = 4*owd
four.commands = {
{ "offset", 0, off, okay },
{ "offset", owd, off, okay },
{ "offset", 2*owd, off, okay },
{ "offset", 3*owd, off, okay },
}
else
-- we don't add (but we could), just patch, and there's no

Hi,
I cleaned up some more backend code. There were some mails about dates

drastic overload is doen with directives. The reason is that the fact
that we can set the date (and traler) is only because it permits
generating pdf files that can be compared. No date as a bad idea anyway.
\setupinteraction[title=My Title]
% \enabledirectives[backend.date=2034-06-07]
\enabledirectives[backend.date=no]
\enabledirectives[backend.trailerid=no]
\starttext
\startTEXpage
\blackrule[height=1cm,depth=0cm,width=4cm,color=darkred]
\stopTEXpage
(there always were command line options for it)
More interesting is asome new experimental code:
\starttext
\dostepwiserecurse{40}{110}{2}{
\startTEXpage[offset=4mm,width=#1mm,align={stretch,normal,tolerant}]
\showmakeup[penalty]%
\orphanpenalties 4 4000 3000 2000 1000\relax
\updateparagraphpenalties
\samplefile{tufte}
\par
\stopTEXpage
}
\stoptext
it's an addendum to the widowpenalties and clubpenalties introduced by
etex but this time it's horizontal; the orphan penalties will be
inserted before spaces (aka spaceskip, xspaceskip and zerospaceskip
glue) so in this case 4000 between the last two 'words' and this
trickery can be used to make sure that the last line is not too short
\orphanpenalties 4 4000 3000 -12000 1000\relax
is also intereting
it's work in progress (i need to play more with it and figure out nice
values for context) .. there might be more such 'simple' useful tricks
Mikael: you can test the math cheat (doesn't make the font nicer).
Pablo : transparencies should work again (wrong alias fixed).
Michal: you can check the dates (as for sure i messed up something).

whatever latex does to make these primes large is unlikely going to

if metadata then
i'll fix it but also clean up the existing code a bit
(much has to do with omitting date and is for comparison reasons)

It works for me (using zint) in the running text, but not in footnotes.
Actually, marginals in footnotes are never displayed. Maybe I shouldn’t expect

we actually can avoid that by using label remapping (i fixed a scanning

dx = -1pt, dy = -30pt ] ;
draw lmt_svg [

\stopTEXpage
one can also have the labels externally
\startluacode
table.save ( "labels-001.lua", {
{ label = "here 1", where = "l", text = "let's try this one out" },
{ label = "here 2", where = "r", text = "let's try this one out

{ label = "here 5", where = "m", text = "this a bit longer
label" },
{ label = "here 4", where = "m", text = "!" },
} )
\stopluacode
\startMPpage
draw lmt_svg [
filename = "labels-003.svg",
labelfile = "labels-001.lua",
] ;
\stopMPpage
the idea is then that in an svg editor one uses symbolic names and when
including those get property typeset
(should work in in next upload; is independent of reported issue)

Re: [NTG-context] Reading ConTeXt metadata values into Lua
On 10/16/2021 10:33 AM, Wolfgang Schuster via ntg-context wrote:
Ramkumar KB via ntg-context schrieb am 16.10.2021 um 06:00:
Hello All,
I was trying to read the value of '\totalnumberofpages' into lua to do
something with it. As an example, see below.
Now, as I understand it, my example would not work as TeX gets the
first go at this and therefore the variable 'pages' is the string
'\totalnumberofpages' and not the actual value itself. And Lua cannot
process this "calculation".
I tried to go thru the manual - *cld-mkiv.pdf *- in the distro but
could not catch on how to read a metadata value (not print). I am sure
that I am missing a small trick somewhere (or is it something more
involved?).
\startluacode
function myFancyCalculations(pages)
-- some fancy stuff but as an example
local myCal = tonumber(pages) + 1
return myCal
\stopluacode
\starttext
\blah
\ctxlua{context(myFancyCalculations("\\totalnumberofpages"))}
\stoptext
Everything gets easier when you use the Lua functions to access the
counter values but be aware the values can be wrong when you're at a
page break.
\startbuffer[pagenumber]
\startluacode
context.starttabulate()
context.NC()
context("Current page")
context.EQ()
context(structures.counters.get("realpage",1,"number"))
context.NC()
context.NR()
context.NC()
context("Last page")
context.EQ()
context(structures.counters.get("realpage",1,"last"))
context.NC()
context.NR()
context.stoptabulate()
\stopluacode
\stopbuffer
\starttext
\dorecurse
{\randomnumber{5}{10}}
{\getbuffer[pagenumber]
\page}
\stoptext
As addendum ... The problem in general with macros is that one doesn't
really knows by looking at the name what actually happens when it
expands, which can be a lot. Now, because \totalnumberofpages is
supposed to 'return' a number and not typeset something styled (which
itself involved macro expansion) you can actually do this:
\startluacode
local n = tokens.getters.macro("totalnumberofpages",true)
print(">>>",type(n),n)
\stopluacode
but beware of the fact that you actually get back a string:
\startluacode
local n = tokens.getters.macro("totalnumberofpages",true)
print(">>>",type(n),n)
local n = tonumber(n)
print(">>>",type(n),n)
\stopluacode
etc etc

It does not contain it; it a copy in the same directory that has never changed.
hm, but i have no clue what this "mtx:..." does
Maybe 'arguments' lives in some namespace?

This will show you what is in the global namespace, maybe 'arg'?
If I put this code in right before the \ifdefined\directlua it prints a lot of

print(k,v) should print two values, key and value

[NTG-context] new upload
Hi,
This midweek upload has something new. There has been some discussion
about footnotes and one thing I noticed when playing with some new
possibilities is that the stretch in topskip (we use a default amount
that long ago was derived from plain tex and is relative to the body
font size) influences the pagebreaks in relation to inserts (footnotes)
in a more significant way than one would expect.
I also noticed that this stretch component is one of the reasons why
sometimes a side float shape will carry over to a next page in spite of
there being room. This relates to \brokenpenalty.
At the end of this mail are some tests that demonstrate this. As a
consequence we now have a "ntop" parameter as well as a shaping related
penalty primitives (parameters):
\shapingpenaltiesmode"FF% set all (future) bits (currently 4)
\shapingpenalty\plushundred % don't go too high
which is currently not enabled by default but might be in upcoming
versions; this also depends on user feedback. It's a non intrusive
extension the LuaMetaTeX engine. I have this setting in my local
preferences file.

There must have been a time when PDF boxes (i.e. CropBox, TrimBox, BleedBox)
worked as they should, but it must have been a short time.
I long ago lost track of what all that means ... decades of pdf ... different
viewers, different interpretations ... validators complaining about things
missing ... i guess that bit (like annotations) will always be in flux (also
because specs came before implementations i guess).
Hm, you implemented these boxes only in 2015, there was not much change in that
regard since then.
Way earlier but it wasn't enabled ... (I'm not going to check ancient
tex live dvd's).
addtopageattributes("CropBox",box) -- mandate for rendering
addtopageattributes("TrimBox",box) -- mandate for pdf/x
-- addtopageattributes("BleedBox",box)
-- addtopageattributes("ArtBox",box)
I remember discussing it with (I think) Pablo and it definityely came up
when we were dealing with these 'standards'.
* BleedBox must be TrimBox plus bleed.
a relative new one, probably also sensitive for interpretation by renderer, imo
worthless
Not worthless; workflow systems in printshops rely on BleedBox and TrimBox.
It’s not about rendering, but imposition and even postprocessing (cutting etc.).
* ArtBox is neglectable for whole layouts (same as TrimBox might make sense),
just interesting in \externalfigure.
also worthless
I agree.
With
\setuppaper[A4][A4,oversized]
I’d expect ConTeXt to set...
* MediaBox and CropBox to the bigger format
* TrimBox to the page format (A4)
* BleedBox also to the page format, while no bleed is defined
well, that's an assumption ... who knows what a printer (driver) does ...
Who sends PDF files directly to a printer (driver)? I know it only from
automated, professional workflows.
Usually printer drivers gets fed by PDF viewers, and I know none that even
*can* print something different than CropBox.
afaik some printers accept pdf (hard to check) but I the fact that a
viewer does something doesn't mean it did years ago (just like at how
crippled tounicode has been / is supported over time)
Beware, \setupbleeding refers only to stretching of images (\externalfigure)!
fwiw, that bleeding options is mostly there to communicate with mp
Good to know. I just browsed the Details manual, didn’t try it yet, since I
scale and move my “bleeding” images differently.
i actually need to pick up that bit ... (some code in my local styles i
need to check) because it can be handy for cover pages (but then i also
need to check if i don't break something
* to define trimoffset, I must know the difference between paper size and sheet size
("oversized" adds 15 mm).
oversized is a convenience feature, in prepress one would define a real, target
size, not rely on a convenience value
But it’s convenient ;) I usually just need a format that is big enough for the
crop marks, and “oversized” does that.
sure, i use it too
% ... and no dependency on interactionscreen!
that's a historic fact ... special pdf features triggered by that command ..
basically tex only has a page size
Of course, but it doesn’t make sense any more, and defining the boxes wouldn’t
hurt anyone. (I’m quite sure, but let them beat me ;))
maybe, but it's also a bit about otr/backend timing, so i need to sit
down on it
Yes, that would mean a backward incompatible change. But how many of us rely on
the strange current behavior?
Please let us fix this!
the problem is as usual documentation and indeed we can have some backward
compatibility issue here ... i honestly have no clue how viewers and printers
react (so if something would be added/changed it would be option driven)
I wouldn’t expect printers (office printing devices) to react at all; I hope
that printers (printshop workers) will react positively to correct boxes in our
PDFs ;)
oh, i'm often surprised about printing houses .. (the best were some
comment on a file having rgb bitmaps while it actually had cmyk outlines
and validators/fixers inlining xforms while setting lines to 0pt widths)
.. and some still use acrobat 4 -)
In some cases it makes sense to have different values on e.g. inner and outer
edges; I feat that would add a plethora of additional parameters
(leftbleedoffset, innerbleedoffset...).
Maybe give a list like in CSS? bleedoffset={3mm,3mm,3mm,0mm} – top, right,
bottom, left order implied; not very “ConTeXt style”.
probably spreads need some treatment (imposition)
Multiple pages on a sheet are not considered by the PDF specs.
yes but what of context imposes
(i'm pretty sure that changes will themselves introduce new issues)
Probable.

Hi,

However, the figures do not line up in the grid of the combination.
I get the correct result with examples 1 and 2 below, but example 3

MWE:

\stoptext
Any hints on what I am doing wrong in example 3?
as in any prodedural language a function as argument gets immediately
executed so you need to delay:
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 1",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 2",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 3",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 4"
)
context.stopcombination()
context.stopplacefigure()
(this is why encoding complex documents completely in a scrtipt language
is non trivial and why for instance these template systems are there
because these accumulate)

I wrote two almost identical files in plain tex and context. When I
generated the synctex file and ran `mtxrun --script synctex --list
x.synctex` I got this:
```
$ mtxrun --script synctex --list context.synctex
mtx-synctex | begin page: 1
mtx-synctex | end page: 1
$ mtxrun --script synctex --list tex.synctex
mtx-synctex | begin page: 1
mtx-synctex | [ 72 82 92 82] : 1 :
/home/nawordar/tests/tex/hello/./tex.tex
mtx-synctex | end page: 1
```
It looks like context generates an incomplete synctext file.
I can't say ... what is missing? Can you figure out what makes Zathura
unhappy?
The context synctex files are definitely less verbose because (1) we
avoid clutter, (2) omit auto-generated content like pagenumbers and so,
(3) collapse ranges (which we can do because we know what we're dealing
with), (4) don't compress (because it makes no sense), (5) ignore
styles, (6) also handle xml, etc. There have been some changes between
synctex 1 and 2 but I don['t keep track of that. Actually, if a 'call
some command' approach would have been chosen we could have better
readable files (in our case lua or so).

sure, so unlikely to happen soon (i have no influence on that)

Here I assign a default value of `nil` to every key, and then check if
the `text` variable is empty before printing it. I would expect the
second macro not to print anything since its `text` should be nil,
instead both macros print 'Some red text', the first one in red and the
second one in blue.
context.setvariables
like any setting, it accumulates unless you group
I have attached a screenshot of the output.
What am I doing wrong?
local style = {
color = "",
text = "",
}
or you can go fancy with:
\startluacode
interfaces.implement {
name = "MyStyle",
public= true,
protected = true,
arguments = "hash",
actions = function(a)
if a.text and a.text ~= "" then
if a.color and a.color ~= "" then
context.color( { a.color }, a.text)
else
context(a.text)
end
end
end
}
\stopluacode
\MyStyle[
text={Some blue text},
color=blue,
]
\MyStyle[
color=blue,
]
\MyStyle[
text={test \em test},
]

Re: [NTG-context] SciTE configuration Mac

I work with MaC OS Big Sur. There are some scite related files in the distribution that you can look at (context/data/scite).

The external lexers depend on the scintillua dll/so and the latest updats drops that (for various reasons) and I now use the OnStyle lua feature of scite.

Re: [NTG-context] Converting LaTeX math to ConTeXt
On 10/10/2021 5:45 AM, Jason Ross via ntg-context wrote: Hello, I'm trying to provide more support for LaTeX math for an Org Mode exporter for ConTeXt. LaTeX is the de facto standard for mathematics in Org Mode. However, the syntax is quite different between LaTeX and ConTeXt. I have a few ideas, but none that I'm happy about. 1. Export LaTeX to MathML then import that into ConTeXt. I don't know how to get this to work. latexmlmath only returns the first row of `align` environments (for me anyway). Also, this would require users to install another program. 2. Typeset equations with LaTeX as standalone pages and then include them as images. This will typeset everything with LaTeX defaults. Also, either equation alignment or equation numbering will break. 3. Hack every math environment I can think of to accept LaTeX syntax (see https://wiki.contextgarden.net/LaTeX_Math_in_ConTeXt). Lots of work, lots of problems as described in the article. End-users could add their own hacks to the template preamble for cases I don't get to. 4. Manually parse and convert every LaTeX math environment to ConTeXt before exporting. Basically a non-starter. I'm wondering what's the best way to go about this.

It's almost like some debug setting has been triggered. But that may be
a red herring. Anyway, I just wanted to report this; maybe some bigger
problem (with the binary or the format?) is lurking somewhere.
no, that's just a more verbose 'overfull box' message ... does adding
\dontcomplain help? (After all you can live with .8pt which smells like
2 * .4pt which is the default rule width so maybe some frame stricks out)

So, just always start at point 0 and then just rotate the cutof piece

On 9/27/2021 3:53 AM, jbf via ntg-context wrote:
The occasional response to a similar question can be found, e.g. on
stackexchange, but none of the responses work for me.
Textadept is very fast at compiling (and does compile correctly). I can
certainly open the pdf independently in various pdf viewers, but I
cannot get Textadept to automatically open, say, Okular (installed on
Linux Mint), at the end of the process.
The last part of the log reads:

pages, 12.492 pages/second

2>/dev/null &
mtx-context | pdfview overhead: 0.001 seconds
system | total runtime: 0.649 seconds of 0.701 seconds
> exit status: 0
Have tried setting up a custom text editor on okular with:
/home/me/.textadept "%f" -e textadept.editing.goto_line(%l-1), as
suggested by one response, but to no avail. Current version of ConTeXt
is 2021.09.17 10:01
Anyone tried Textadept successfully and might have a suggestion?
I tried to launch textadept with the setup that is in the distribution
and it worked ok with the textadept version on my machine. There is
however a hickup in launching the pdf viewer and then after a while i
have to hit escape (windows version of textadept). A second run doesn't
work well. So, I guess there is somethign with subprocesses.
The output pane is, as with scite that also uses scintilla, quite fast
indeed because it has large refresh delays. For those on windows: the
last years the windows terminal (cmd etc run on top of that) is also
quite ok. Older versions of cmd had a char-by-char refresh which is not
something that goes well with tex logging. On unix one has larger delays
so there it's better but tven then font rendering can slow things down.
Now to textadept: in order to check this 'launch viewer' delay I
installed the latest version and the code that we ship with context no
longer runs (quits on some path creation, then when commented on some
color/style settings and finally loops in finding a lexer). I know (from
scite) that there has been updates to the scintilla lexer interface
(again) that I need to look into but in the meantime i wonder if I
should do that (although ta is advertised as flexible and configureable
it i guess it mostly applies to the code it comes with so maybe it's not
meant not be used as i want to, as a framework; get me right: i don't
complain about changes: that comes with open source and free and such,
it's more about 'should i stick to it and spend time on it').
That said, I do use scite but run our own lexing on top of the derived
ta lexing dll (among the reasons for having our own lexing code are
'performance' (large files should load and lex fast), nested lexing,
extra features, spell checking etc. Also, we already had lexers. I now
wonder if I should not simply roll out my own plugin in scite (which
also makes it possible to do some more) instead of relying on ever
changing interfaces (changes are fine, but keeping some compatibility
would be nice).
My backup plan (in case it all stops working) is VScode but even that
one keeps changing (e.g. the way extensions are enabled on the command
line) and it doesn't have the convenient 'run some program based on
suffix' feature that other editors have.
So ... the question is: should I waste time on editor support at all,
that is: wrt stuff added to the distribution. I'm okay with making
things better and have no problem adepting, but we're not talking about
it getting better here (e.g. ta already got pretty large wrt to binaries
and libraries, so it lost a bit of its charm for me and it's a pitty
that the scite lua interface doesn't have lpeg built in natively.)
(I might eventually end up running editors in an ancient virtual machine.)

best numerator and denominator, but Taco Hoekwater, Harald Koenig
and Mikael Sundqvist figured
it out in this interactive session. The error messages have been
adapted accordingly and the
scanner in the |tex| library also handle it. One |dk| is 6.43985pt.
There is no need to make
\METAPOST\ aware of this unit because there it is just a numeric
multiplier in a macro package.
From Wikipedia:
In issue 33, Mad published a partial table of the \quotation
{Potrzebie System of Weights and
Measures}, developed by 19-year-old Donald E. Knuth, later a famed
computer scientist. According
to Knuth, the basis of this new revolutionary system is the
potrzebie, which equals the thickness
of Mad issue 26, or 2.2633484517438173216473 mm [...].
*/
This is a follow up of a suggestion by Hraban (on the meeting attendents
list): a new unit. We have 'sp' for an unscaled unit (kind of the
internal one, also used at the lua end), 'ex', 'em', 'px' as relative
units (the handy ones), 'mu' for math (sort of relative and adaptive
too), which leaves 'cm', 'mm' (popular and valid SI), 'pt' (natural to
typesetting), 'bp' (related to postscript and pdf, the unit that
competing-to-tex programs use), 'dd' and 'cc' (for Tomas Hala), 'in'
(for stubborn non SI users) and now also 'dk' (for Don Knuth fans).
So, Hraban (who organizes next year meeting) can now do:
\setupbodyfont[dejavu,1dk]
\starttext
1dk = \the\dimexpr1dk = \the\dimexpr2.2633484mm
{\definedfont[Mono*none @ 6pt]test}
{\definedfont[Mono*none @ 1dk]test}
\stoptext
And in case one wonders: this few line addition doesn't harm performance.

Re: [NTG-context] Exclude bibliographic entries from list even when cited with \cite
On 9/16/2021 8:45 PM, Joey McCollum via ntg-context wrote:
Hi,
It's taken a couple weeks, but I nearly have a working bibliographic
rendering for SBL style ready. I'm hosting the .lua and .mkvi files I
have so far, as well as a test .bib and .tex file, on GitHub at
https://github.com/jjmccollum/context-sbl
<https://github.com/jjmccollum/context-sbl>. The look of the rendering
seems to be correct for all of the examples, so the last remaining tasks
mostly concern some lower-level technical issues.
Because of the way that SBL style renders entries that are contained in
other works (e.g., a chapter in a book that is part of a multivolume
collection), it seemed natural to accommodate this by allowing entries
to have cross-references to other entries. The rendering process can
then be handled through recursive subcitations with different
alternatives. In general, I handle these subcitations with the \textcite
command, so that "higher-level" entries are not added to the list when
they are only subcited.
An important guideline that I still have to implement works in the
opposite direction: it says that entries in certain categories should
not be added to the list, but the books or collections containing them
should be. I think I could make this work for the subcitation using the
\listcite or \cite command recursively. But is there a way to
conditionally handle whether or not to add the entry to the list after I
invoke the \cite command, or is this built into the \cite command at a
low level? If I had to, I could define an \autocite command that does
all of these checks first, but if it's possible to keep the common \cite
command instead of forcing users to use a different command, that would
be preferable.
a few quick remarks (i'll look better into it later)
% Various Lua macros for parsing and conversion
\startluacode
sblhelpers = sblhelpers or {}
i think we should havea namespace for these kind of things in order not
to polute the global namespace
something publications.btx and then publications.btx.slb = { }
this is tricky and will clash:
\def\ordinal#1{\ctxlua{sblhelpers.ordinal([==[#1]==])}}%
\def\convertdate#1{\ctxlua{sblhelpers.convertdate([==[#1]==])}}%
\def\serializelocationpublisher#1#2{\ctxlua{sblhelpers.serializelocationpublisher([==[#1]==],[==[#2]==])}}%
\def\serializevolumenumberdatepage#1#2#3#4{\ctxlua{sblhelpers.serializevolumenumberdatepage([==[#1]==],[==[#2]==],[==[#3]==],[==[#4]==])}}%
% Define some helper functions for subcitations
\let\btxparenttag\empty% the tag of the entry subciting the current one
\def\btxprintpubl{yes}% yes/no indicating whether publication
information should be specified for the current citation or subcitation
\let\btxcurrentsubcitetype\empty% the type of subcitation we're invoking
here
\def\btxsblordinal
is better, but as you're using protection, even better is
\def\btx_sbl_ordinal
i also wonder about the
\clf_btxdirect
we need a \btxdirect... (have to think about a name) because one never
knows how a lowlevel command evolves (or at least i shoudl somehow make
a not that it can't evolve (or make a keyword driven variant) ... idem
for \clf_author (btw, no need for these end-of-line % in texdefinitions
I'll add string.wordsplitter so that
local andsplitter = string.wordsplitter("and")
local a = andsplitter("a and b and c")
local a = andsplitter("a and b and c")
local a = andsplitter("aand band c")
all work as expected
i'll add an extended publ-imp-author.mkvi to the distribution, the other
ones can come later (including the manual).

Is there another file I'd have to change to make "invertedfirst" a working authorconversion? Is there a similar block of code in publ-ini.lua where I should be implementing this change instead?

Is this some debugging leftover or am I supposed to understand what’s wrong? ;)
hm, what command triggers that?

[NTG-context] update
Hi, I uploaded a new lmtx (had forgotten to to it friday) . There are not that many visible changes but on is that i'm playing with some 'improvements' to inserts. Hopefully there are no side effects but the idea is to have somewhat better (more robust and predictable) support for e.g. footnotes in situations that are not natural to tex (like columns). The first mechanism to benefit from that is page columns but all that is a stepwise process. I keep track of that in yet another lowlevel manual. These column things are on the agenda for next month and beyond. (In a next upload the new marking and tabulate optimization might become default but for now i test that locally.)

Actually it is an alternate, but only partially.
There is a table on the github page with the results from all alternatives.
Look at section "Character Variats" on https://github.com/be5invis/Iosevka
With fonts like that we might end up in issues anyway:
\definefontfeature[default:test][default][mlxx=yes,wflm=yes]
\definedfont[file:iosevka.ttc(Iosevka)*default:test] :> <>
e.g.
WFLMWolfram Language (Mathematica)
so we get font specific 4 char feature names that themselves have script
/ language specifications (like latin default and cyrillic serbian
wolfram) ... these could have been ss* features (after all, cv and ss
are wildcards and opentype has never been that consistent), not that it
matters much because it gets processed anyway, but it's a clear signal
that anyone can roll out adn use any feature name

@Marcel: I suggest to load ttc fonts with the file option.

\stoptext
as it experimental anyway, i changed this trick to
\definefontfeature[default:test][default][cvxx={repeatlast:3}]
repeatmiddle and repeatfirst also supported (it also permits context
users to play with runtime feature definitions using multiples that act
as extensibles)

Hi,
ConTeXt has some issues with the character variant features of the
Iosevka font available at
https://github.com/be5invis/Iosevka/releases/download/v10.1.1/super-ttc-iosevka-10.1.1.zip
E.g. the following document
\definefontfeature

What is the number supposed to indicate ? It is not an alternate, right?
\definefont
[SomeFont]
[name:iosevka*default:test]
\starttext
\SomeFont
I live in a dot-heavy world.
\stoptext
has six dots instead of one dot over each "i". Tests with multiple other
font shapers and inspection of the font file confirmed that this is not
intentional behavior.
Could you take a look at that?
(Based on a luotfload bug report at
https://github.com/latex3/luaotfload/issues/202)
when a number is specified for a multiple and the is > 1 we repeat the
last glyph ... this is a 'secret' feature that (already a while ago) we
added when discussing / testing a experimental arabic font in
combination with a paragraph optimizer ... normally users will say 'yes'
and not give a number
i can make that a 'context only' feature if needed

Re: [NTG-context] Axis macro in MetaFun

Dear All,
I am truly grateful for the new additions to MetaFun. It has greatly helped me
in producing neat drawings for my academic work. In this connection, I have a
few queries.
Currently I am using PGFPlots (with ConTeXt) to draw simple plots from CSV
data. I was wondering if there is any way to do the same in MetaFuns. That is,
is it possible to do something like the following in order to obtain a line
plot of the values in the 'data.csv' file? Also is it possible to have the
'labels' be the identical for all points in a given list?
\startMPcode
draw lmt_axis [
sx = 2mm, sy = 2mm,
nx = 80, ny = 40,
tx = 15, ty = 15,
list = {
[
connect = true,
color = "darkblue",
close = true,
points = {data.csv},
labels = {"•"},
]
},
] withpen pencircle scaled 0.5mm;
\stopMPcode
It depends on how one has data in the csv, You can patch mlib-scn.lmt
(line 659)
if type(v) == "table" then
return injectpath(v,connector,close)
elseif type(v) == "string" then
local code = load("return " .. v)
if code then
return code()
end
else
return injectpair(0,0)
end
then a string represents a function:
\starttext
\startluacode
io.savedata("temp.csv", "x,y\n10,10\n20,40\n30,30\n")
local mycsvsplitter = utilities.parsers.rfc4180splitter()
function MP.MyPoints(name)
local data = io.loaddata(name)
local list = mycsvsplitter(data)
table.remove(list,1)
for i=1,#list do
list[i][1] = tonumber(list[i][1])
list[i][2] = tonumber(list[i][2])
end
mp.inject.path(list)
end
\stopluacode
\startMPcode
draw lmt_axis [
sx = 2mm, sy = 2mm,
nx = 80, ny = 40,
tx = 15, ty = 15,
list = {
[
connect = true,
color = "darkblue",
close = true,
points = "MP.MyPoints('temp.csv')",
labels = {"•"},
]
},
] withpen pencircle scaled 0.5mm;
\stopMPcode
\stoptext
we can of course have some predefined and when we can agree on how these
files loo, adding a "csv" is no big deal ... it's all about consistent
interfacing
