Ah, okay. I was under the impression that the LMTX standalone
distribution carried a ton of TikZ patches and that ConTeXt patches
weren't really merged upstream, but it sounds like there are only a
couple small patches and upstream does merge ConTeXt patches. I'll
rebase my PR and check with upstream again. Thanks!

I've seen a few TikZ bugs/patches resolved on this list, and I know that
the LMTX standalone distribution carries patches for TikZ (although
fewer than I thought?), so this seemed like the right place to start.

I need to rebase my current PGF PR anyways, so I'll add this in with it.

[NTG-context] PDF, runner, and TikZ patches
Hi all,
I've had a few patches applied to my installation for a little while
now, so I figured that I should send them in. There's a diff at the end
of the email, and the modified files are attached [but rejected by the
mailing list, so sent separately to Hans]
* In the definition of "featurecreep()" in "lpdf-mis.lmt",
"structures.pages.tobesaved[i].status" should be "[...].state" to
match the definition of "pages.save" in "strc-pag.lua".
* For the "resultof" runner in "util-sbx.lmt", the current io.popen
mode only works with Windows. See the definition of "l_checkmodep" in
"liolib.c".
* Some of the pgfplots 3D shaders appear to be broken,
see https://tex.stackexchange.com/a/708121 .
* The TikZ "RGB" colour model does not currently work properly. This is
internally used by "\usepgfplotslibrary[colorbrewer]" among others.
See https://github.com/pgf-tikz/pgf/pull/1130 .
Thanks,

[NTG-context] \intertext and highlighting with \alignhere/\breakhere
Hi all,
Often I want to include a sentence/paragraph in the middle of a long
multipart formula. With the old \startalign/\stopalign formulas, I could
use \intertext{...} to do this, but this doesn't work with the new
\alignhere/\breakhere formulas. I've managed to find a "solution" for
this, although I'd prefer something a bit less hacky. Any ideas?
Also, is there a way to highlight an equation across an \alignhere? Once
again, I've found a "solution", but like before, it's pretty hacky.
Example files are attached.
Thanks,

\numexpr stops at the first non-expandable or non-digit token. If
\clf_last[xy]pos expands to an integer, then that's the \relax, but if
it expands to a float, then that's the decimal point.
With Lua, adding, subtracting, or multiplying two integers will give you
an integer, but dividing gives you a float. So somewhere in the backend,
the vertical position is probably divided but the horizontal position is
only added or subtracted.
To fix this, change lines 2344--2345 of anch-pos.lmt from
implement { name = "lastxpos", actions = function()
context(jobpositions.lastx) end }
implement { name = "lastypos", actions = function()
context(jobpositions.lasty) end }
to
implement { name = "lastxpos", actions = function() context("%.0f",
jobpositions.lastx) end }
implement { name = "lastypos", actions = function() context("%.0f",
jobpositions.lasty) end }
Thanks,

This is fairly close to what you're looking for I think (the manual, not the package itself): http://mirrors.ctan.org/macros/luatex/generic/lua-widow-control/lua-widow-control.pdf The source is a little messy, but I've used it in a bunch of other documents and it seems fairly robust: https://github.com/gucci-on-fleek/lua-widow-control/blob/7c4544/docs/manual/lwc-manual.mkxl#L167-L234 There aren't any page numbers for the subsections in that, but you should be able to add those inside the definition of \SubsectionTOCcommand with either #3 or \currentlistentrypagenumber.

[NTG-context] lpdf.registerfontmethod
Hi Hans,
In lpdf-emb.lmt, there's a commented-out definition of
lpdf.registerfontmethod that I'd like to use. I've uncommented this in
my installation and it's worked pretty well for me, so can you please
uncomment/enable this by default in the distribution?
If you want further background, this is how I'm using it:
lpdf.registerfontmethod("rawpdf", function(filename, details)
return
details.properties.indexdata[1],
0.001,
function(char)
return char.code, char.width / t3_to_sp
end,
function() end,
function() end
end)
local function make_glyph(codepoint, unicode, width, height, code)
local spec = {
width = width * t3_to_sp,
height = height * t3_to_sp,
depth = 0,
unicode = { utf8.codepoint(unicode or "", 1, -1, true) },
code = width .. " 0 d0 " .. code,
}
local tfmdata = fonts.hashes.identifiers[font.current()]
tfmdata.characters[codepoint] = spec
fonts.dropins.swapone(
"rawpdf",
tfmdata,
{ code = spec },
codepoint
)
fonts.constructors.addcharacters(
font.current(),
{ characters = { [codepoint] = spec } }
)
end
I specifically need something that writes out a raw PDF stream. I'm
using this to write a 4000+ page PDF file to be included by pdfTeX, so I
can't have any XObject indirection or similar, otherwise the number of
objects skyrockets and pdfTeX (+qpdf) gets really slow.
If you're curious, the actual code where I'm using this is here:
https://github.com/gucci-on-fleek/unnamed-emoji/blob/master/source/svg-to-pdf.cld
https://github.com/gucci-on-fleek/unnamed-emoji/blob/master/source/unnamed-emoji.lua
I know that what I'm doing in the .cld file is wildly unsupported, but
I'm the only one who will ever need to run that. I am planning on
distributing the .lua file though, so I'd like to get this change in the
distribution.
I'm also open to using a different interface instead if you don't want
to publicly-expose lpdf.registerfontmethod.
Thanks,

[NTG-context] SVG converter bugs
Hi Hans,
I've been using the SVG->MP converter and I've found a few bugs. Most of
the bugs are with "weird" SVG input, but I have no control over the
input, and the metadata on most of the files shows that it was exported
from Adobe Illustrator which is (unfortunately) quite popular. I've
tested all of the below with the latest ConTeXt.
If you give Metapost an out-of-order gradient, it produces an invalid
PDF. Both pages in this example:
\startbuffer[gradient]
http://www.w3.org/2000/svg;>
\stopbuffer
\starttext
\startTEXpage
\includesvgbuffer[gradient]
\stopTEXpage
\startMPpage
fill unitsquare xyscaled (200,100)
withshademethod "linear"
withshadecenteronefraction (0,1)
withshadecentertwofraction (0,0)
withshadestep (
withshadefraction 0
withshadecolors (green, green)
)
withshadestep (
withshadefraction 0.75
withshadecolors (blue, green)
)
withshadestep (
withshadefraction 0.25
withshadecolors (green, blue)
)
withshadestep (
withshadefraction 1
withshadecolors (green, blue)
)
;
\stopMPpage
\stoptext
write this to the PDF
/Bounds [
0
0.75
0.25
]
which is invalid and renders incorrectly in every PDF reader that I've
tested. This is what the SVG 1.1 spec has to say:
Each gradient offset value is required to be equal to or greater than
the previous gradient stop's offset value. If a given gradient stop's
offset value is not equal to or greater than all previous offset values,
then the offset value is adjusted to be equal to the largest of all
previous offset values.
The following SVG renders incorrectly, but replacing the 0% stop with
the commented one fixes it:
http://www.w3.org/2000/svg;>
Using a gradient as the stroke colour outputs an invalid colour to
MetaPost. This example:
\startbuffer[gradient]
http://www.w3.org/2000/svg;>
\stopbuffer
\startluacode
print(metapost.svgtomp{data = buffers.getcontent("gradient")})
\stopluacode
gives this output:
[...]
withcolor "url(#gradient)"
[...]
"stop-opacity" seems to be ignored:
\startbuffer[gradient]
http://www.w3.org/2000/svg;>
\stopbuffer
\startTEXpage
\includesvgbuffer[gradient]
\stopTEXpage
Finally, "display:none;" doesn't work:
\startbuffer[gradient]
http://www.w3.org/2000/svg;>
\stopbuffer
\startTEXpage
\includesvgbuffer[gradient]
\stopTEXpage

Here's a questionable Lua-based solution:

function userdata.post_lettrine(head)
nodes.tasks.disableaction("finalizers", "userdata.post_lettrine")
if tex.prevgraf < math.abs(tex.hangafter) then

end
return head
end
nodes.tasks.appendaction("finalizers", "before", "userdata.post_lettrine")
nodes.tasks.disableaction("finalizers", "userdata.post_lettrine")
function userdata.next_par(head)
nodes.tasks.disableaction("processors", "userdata.next_par")
if head.next.id == node.id("glue") and
head.next.subtype == 20
then
head.next.width = userdata.hangindent
end
return head

Normally manipulating nodes inside the callbacks is the wrong way to do
something, but in this case, that's exactly how the standard initial
code works.
We need to modify the "default" alternative since "\setupinitial"
provides no way for us to set a different alternative. A better solution
would be to provide a new alternative so we wouldn't need to make
questionable overrides to the base code.

Re: [NTG-context] Super slow installation

Re: [NTG-context] LuaMetaTeX doesn't find files when symlinked

This is probably not the same issue, since the path "context-linux- 64/bin/mtxrun" suggests that that isn't a symlink. (Well, it is a symlink mtxrun => ./luametatex, but that email is about multi-level symlinks like /usr/bin/context => /usr/local/texlive/2023/bin/x86_64- linux/context => ./luametatex) To compile a document, you almost certainly want to use "context" instead of "mtxrun".

[NTG-context] LuaMetaTeX doesn't find files when symlinked
Hi Hans,
With the LuaMetaTeX-based ConTeXt wrapper, it's not generally possible
to run ConTeXt from a symlinked binary in another directory. This shows
up if someone makes symlinks in "/usr/bin" so that they can avoid adding
anything to their $PATH.
If you make run a symlink to the LuaMetaTeX-based ConTeXt wrapper, it
looks for texmfcnf.lua relative to the symlink location, not the symlink
target. With the old LuaTeX/kpse-based wrapper, the script would look
for texmfcnf.lua relative to the symlink target.
I know that my description above is terrible, so here's a demo:
$ bin=$(mtxrun --expand-var TEXMFOS | head -1)/*
$ cd $(mktemp -d)
$ ln -s $bin/luatex $bin/luametatex $bin/context $bin/context.lua
$bin/mtxrun $bin/mtxrun.lua .
$ ./context --nofile
$ ./context --luatex --nofile
Running the above commands used to work with the old LuaTeX/kpse-based
wrapper, but it doesn't work any more. I was able to ""fix"" this by
adding the lines
if os.selfpath then
environment.ownbin = lfs.symlinktarget(os.selfpath .. io.fileseparator
.. os.selfname)
environment.ownpath = environment.ownbin:match("^.*" .. io.fileseparator)
else
environment.ownpath = kpse.new("luatex"):var_value("SELFAUTOLOC")
environment.ownbin = environment.ownpath .. io.fileseparator .. (arg[-2]
or arg[-1] or arg[0] or "luatex"):match("[^" .. io.fileseparator .. "]*$")
end
to mtxrun.lua, right below the line
package.loaded["data-ini"] = package.loaded["data-ini"] or true
but this is obviously not a very good fix.
There are some threads with more details at:
https://tug.org/pipermail/tex-live/2023-March/049028.html
https://gitlab.com/islandoftex/images/texlive/-/issues/30
Those links only discuss TL, but I get the same issue if I make a symlink
to the standalone ConTeXt files.
Thanks,
-- Max

Re: [NTG-context] update
Hi Lynx, > * How can I be sure that the standalone version is the one being > implemented? It depends on what your $PATH is set to. On Linux/macOS, you can run $ type -ap context to list all the ConTeXts in your $PTAH. The first one in that list is the one that will be ran by default. If you want to always run the standalone version, then you'll need to make sure that your ConTeXt directory comes before your TL directory in your PATH. On Linux/macOS, you'd add something like export PATH="/path/to/context/bin/:$PATH" to your ~/.profile; on Windows, you can use the "setx" command. Googling something like "add location to path" will get you more specific instructions for your OS/shell. > * How do I update the standalone version Just run the installer again. On my system, I run $ cd /opt/context $ sudo sh ./install.sh > (I assume that, as of today, > it is already the most up-to-date version Correct. > if and when it is > required or desired to do so? You only need to update ConTeXt if a new update fixes a bug that affects you or adds a new feature that you want. Most updates are announced on the list, so you could just update whenever you see a new update. Or you could just try updating once per week. You could also just never update. Up to you. The general recommendation is to save an old copy of the ConTeXt folder before you update in case something breaks. I've never done this before though since I can usually patch the bugs myself, and I can always fall back on the version in TL if something is really broken. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___
Re: [NTG-context] update
Hi Hans, > I actually dont' know the rules for updating texlive but there are > definitely updates. The rules are: - Packages and formats are updated about 24 hours after a new version is uploaded to CTAN. - Binaries are only updated once-per-year. But there are also some special cases: - The luatex binary will be updated shortly for "reasons" (details to be made public later). - The luametatex binary is allowed to be updated whenever. https://tug.org/pipermail/tex-live/2023-March/049058.html - I have no idea how ConTeXt is added to TL, but it doesn't appear to be through the usual automatic CTAN sync. > Basically tex live is the yearly snapshot. Because you're allowed to update luametatex at will and luatex hardly changes, you could update the ConTeXt in TL more than once per year. There's no need for it to get as many updates as the standalone distribution, but it would be nice to get an update every 3 months or so. (I have no idea how much work this is for you+Mojca, so it's maybe not worth the effort). > But you can just install the lmtx installation alongside (it's small > compared to tex live) and have the best of both worlds. The lmtx > installation also has mkiv. It also comes with the fonts that match > what we expect in context (as fonts get updated or changed). Lynx, I'll second this recommendation. The standalone lmtx distribution is updated weekly-ish, uses less than 400MB disk space when installed, and coexists happily with TL. The only downside is that it doesn't have a friendly installation GUI like TL does. Even then, I personally find it easier to install than TL.

Re: [NTG-context] /usr/bin/env texlua no such file or directory; ~/context/tex is not a valid TEXROOT path; no file plain.tex
Hi Carlos, I think that you may be installing the old ConTeXt MkIV distribution instead of the new ConTeXt LMTX. ConTeXt LMTX doesn't distribute "texlua" at all, and running "./install --modules=all" doesn't make sense with LMTX (since the installer can't install modules). From what link did you download your ConTeXt? If it started with "minimals.contextgarden.net", then that's the old ConTeXt; if it started with "lmtx.pragma-ade.com" then it's the new LMTX. The wiki page that you want is https://wiki.contextgarden.net/Installation#Unix All the other wiki pages are outdated. This is just a wild guess, so I may be very wrong here. If this doesn't work, then what do you get when you run type -ap context type -ap luatex type -ap texlua type -ap luametatex /full/path/to/texlive/2023/context --version /full/path/to/context/standalone/context --version ls -la /full/path/to/texlive/2023/context ls -la /full/path/to/context/standalone/context (I'll also add that I have both the ConTeXt and TeX Live versions of "context" installed on Linux, so it's definitely possible.)

That does make the output more consistent, but not in the way that I'm
wanting. My real code looks more like this:
\definefontfeature[default][default][tlig=yes, tquo=yes, trep=yes]
\startbuffer[test-bib]
@article{one,
author = {``Auth\v{o}r---One''},
}
@article{two,
author = {``Authǒr---Two''},
}
\stopbuffer
\usebtxdataset[test-bib.buffer]
\startluacode
for key, value in
table.sortedpairs(publications.datasets.default.luadata) do
print(key, publications.prerollcmdstring(value.author))
end
\stopluacode
publications.prerollcmdstring seems to run before any of the
replacements/ligatures, so with your fix I get this as the output:
one ``Authǒr---One''
two ``Authǒr---Two''
while with my suggested fix I get:
one “Authǒr—One”
two “Authǒr—Two”
I'm using a CLD document to convert a bunch of old .bib and .tex files into
Lua tables (which I'll then convert into XML). I can't modify any of the
input files, so I'll need to somehow deal with all the LaTeX-style input.
Using publications.prerollcmdstring + characters.tex.toutf seems like the
best way to do this, but I'm open to a different solution if you have any
suggestions.

Someone else reported this issue to the TikZ GitHub:
https://github.com/pgf-tikz/pgf/issues/1248
so it's definitely not just you. There's also a suggested (temporary)
solution there. For a more permanent solution, someone will need to patch
the m-tikz.mkXX files distributed with ConTeXt.

[NTG-context] characters.tex.toutf bug
Hi Hans,
"characters.tex.toutf" only works if there is a backslash somewhere in
its input string. This leads to some really surprising behaviour in the
following example:
\definefontfeature[default][tlig=no, trep=no]
\startbuffer[test-bib]
@article{one,
author = {``Author---\v{O}ne''},
}
@article{two,
author = {``Author---Two''},
}
\stopbuffer
\usebtxdataset[test-bib.buffer]
\starttext
\placelistofpublications[method=dataset]
\stoptext
Removing the following lines
elseif not find(str,"\\",1,true) then
return str
from the definition of "characters.tex.toutf" in "char-tex.{lmt,lua}"
fixes this issue for me.

Re: [NTG-context] Float control
Hi Denis, > The floats where jumping around, appearing in a different order than > in the source file Tables and figures can appear in different orders than each other, and a top float could appear at the top of the page that it is mentioned, but if you ever see Figure 2 before Figure 1 or a float appearing before it is placed in the source (with the exception of the top issue), then you've probably found a bug. > some positioning keys had not the intended effect (e.g. top) I've had mixed results with some of the positioning keys too, but "top" should generally work okay. If you're using columns, weird stuff can sometimes happen with top/bottom floats, but you should still be able to make them work. You can also try adding \setupfloat[ntop=100] at the start of you're document. I've had that fix an otherwise- unexplainable bug once. > I know, TeX's float positioning algorithm should be rather reliable > and stable Not as much as you would expect.

Re: [NTG-context] [m-database] How to properly add module arguments?
Hi Paul,
> I added a stanza to the appropriate interface file:

> I modeled that after the stanza for the argument `strip`. I think
> that's the only thing I need to do in the interface file.
I'd recommend completely ignoring the interface i-*.xml files. They
don't do anything particularly useful for a third-party module.
>\c!skipheader=\v!no, % <- Added, following the pattern with strip
This line is your issue. Inside \unprotect...\protect, "!" is treated as
a letter, so you're trying to expand the value of the macro
"\c!skipheader". The problem is that that macro isn't defined anywhere.
Backing up a little further, the \c!... commands are all string
*C*onstants. If you see a command with a name like \c!blah, it almost
certain expands to exactly the string "blah". Why is this useful? Well,
if you run ConTeXt in another language, then the \c!... commands will
instead contain that string but in the other language. So something like
\c!left would be "left" in English, "gauche" in French, "links" in
German, "vlevo" in Czech, etc.
You could define \c!skipheader to just be "skipheader", or you could
give it a translated value for 10 or so languages. But the easier
solution is to just use the string "skipheader" directly:
\setupdatabase
[\c!separator={,},
\c!quotechar=,
\c!commentchar=,
\c!strip=\v!no,
skipheader=\v!no, % <-- HERE
\c!before=,
\c!after=,
\c!first=,
\c!last=,
\c!left=,
\c!right=]
As a more general suggestion, it is usually a really bad idea to modify the
standard ConTeXt files since any changes will be overwritten on updates.
Probably the best solution is to make a new file called "t-xdatabase.mkiv"
stored in your texmf-local/, start the file with "\usemodule[database]"
then add any changes after that. Or, just copy and paste the original file
into your new file. (Maybe you were doing this already though)
Hope this helps,

Page 34 of the publications manual lists the various styles:

\parencite is like \cite[authoryear][article] and \textcite is like

but you can define your own wrappers with something like
\define\parencite[1]{\cite[authoryear][#1]}

difference in the \parfillskip values and a 0.12pt difference between
the "o" widths.
Maybe it's just a coincidence, but it seems odd that enabling expansion
makes no difference with the latest version (A/B) and that latest with
no expansion (A) gives identical results to the old version with
expansion (D). Plus, a 6.6pt difference in glue lengths seems like a lot
for an accuracy change.
I could very easily be wrong here, but something seems off to me.

Re: [NTG-context] thousand separator space
Hi Jan,
> Why is there an additional space after the thousand separator in math mode?
Because something like
${\mathbb N} = \{1,2,3,4,\dots\}$
would look quite bad without any space between the numbers.
(The technical reason is that commas have the math class \mathpunct,
meaning that TeX automatically adds a space after them. Adding the
braces converts it to \mathord, which doesn't add any spaces.)
> And what can I do to get rid of the additional space?
The TeXbook recommends that you wrap the comma in curly braces
$x = 1{,}000$
but there's probably a ConTeXt \setupxxx command that would have the same
effect.
Many European languages use the comma as a decimal separator, so I'd
generally recommend using a thinspace (\,) instead of a comma as a
thousands separator to avoid confusion.

The \hss isn't the problem here. The problem is actually with the box.
When you manually make the \hbox like that, I think (although I could be
wrong) that you're bypassing all of TeX's glue calculations. You should
probably use "node.hpack" instead:

c.char = string.byte("c")
c.font = font.current()
local hss = node.new("glue")
hss.stretch = 65536
hss.stretchorder = 2
hss.shrink = 65536
hss.shrinkorder = 2
hss.width = 0
local box = node.hpack(hss + b, "exactly", 0)
box.shift = -tex.sp("1ex")

a.next = box
box.next = c

This example: \startluacode local stretch_order = "stretch_order" local shrink_order = "shrink_order" if status.luatex_engine == "luametatex" then stretch_order = "stretchorder" shrink_order ="shrinkorder" end local glue = node.new "glue" print(node.getglue(glue)) node.setglue(glue, 1, 2, 3, 4, 5) print(node.getglue(glue)) glue.width = 1 glue.stretch = 2 glue.shrink = 3 glue[stretch_order] = 4 glue[shrink_order] = 5 print(node.getglue(glue)) node.setglue(glue, 1, 2, 3, 4, 5) print(node.getglue(glue)) \stopluacode produces this output in MkIV: 0 0 0 0 0 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 but this output in MkXL: 0 0 0 0 0 0 0 0 0 0 1 2 3 4 5 0 0 0 0 0 Thanks, -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___
Re: [NTG-context] "true" units in LuaMetaTeX
Hi Hans, > Anyway, I'll check it. Is anyone still using this "true" actually? I've been playing around with LuaMetaLaTeX/LuaMetaPlain recently https://github.com/zauguin/luametalatex and plain.tex uses truein for typesetting the footnote rule. It's trivial to fix that specific case, but I'm finding 140 other files in TeX Live that use the "true" dimensions, 69 of which that have been updated in the past 3 years. I doubt that anyone in ConTeXt uses the "true" dimensions though. > I don't check github, it's mostly there for the compile farm and > intermediate testing (e.g. math stuff) so sending me a mail is ok.

[NTG-context] "true" units in LuaMetaTeX
Hi Hans,
The unit scanner in LuaMetaTeX fails for any of the "true" dimensions.
With this test file:
\starttext
\vrule width 1truein height 1pt depth 0pt\relax
\vrule width 1in height 1pt depth 0pt\relax
\stoptext
I get this output:
tex error > tex error on line 2 in file ./lmtx-true.tex: Valid keyword
expected, likely 'true'
\vrule width 1truei
n height 1pt depth 0pt\relax
1 \starttext
2 >> \vrule width 1truein height 1pt depth 0pt\relax
3
4 \vrule width 1in height 1pt depth 0pt\relax
5 \stoptext
6
I was able to fix this with the patch at the end of the email.
(Also, how do you want patches sent? Via email to the mailing list,
emailed directly to you, as a pull request on GitHub, or something
else?)
Thanks,
-- Max

[NTG-context] Missing parinitskips in \normalizelinemode=0
Hi Hans,
When running in \normalizelinemode=0, the \parinitleftskip and
\parinitrightskip nodes are either nonexistant or invisible from Lua,
causing tex.linebreak to not work correctly.
This sample file:
\enabledirectives[system.callbacks.permitoverloads]
\normalizelinemode=0
\directlua{
callback.register("pre_linebreak_filter", function(head)
tex.preparelinebreak(head)
local list, info = tex.linebreak(head)
print(info)
return head
end)
}
\starttext
\input knuth
\stoptext
Produces this output:
luatex warning > linebreak: list seems already prepared
luatex warning > linebreak: [ leftinit | rightinit | leftfill | rigthfill ]
expected
nil
Thanks,
-- Max

Re: [NTG-context] atan2 function

They both give the same results, but "angle" gives a result in degrees
while "atantwo" gives a result in radians. This demo:

vardef atantwo( expr dy, dx ) =
save theta;
numeric theta;
theta := 0;
if (dx > 0):
theta := atan( dy / dx );
elseif (dx < 0) and (dy >= 0):
theta := atan( dy / dx ) + pi;
elseif (dx < 0) and (dy < 0):
theta := atan( dy / dx ) - pi;
elseif (dx == 0) and (dy > 0):
theta := pi / 2;
elseif (dx == 0) and (dy < 0):
theta := -pi / 2;
fi;
theta
enddef;
def showangles(expr dx, dy) =
message "---"
message "atantwo " & decimal atantwo(dy, dx)
message "angle " & decimal (angle(dx, dy) * pi / 180)
message "angle " & decimal angle(dx, dy)
message "(" & decimal dx & ", " & decimal dy & ")"
enddef;
showangles(1, 0);
showangles(1, 1);
showangles(0, 1);
showangles(-1, 1);
showangles(-1, 0);
showangles(-1, -1);
showangles(0, -1);
showangles(1, -1);
\stopMPpage
gives:

Re: [NTG-context] atan2 function
Hi, > How is atan2 called? I rolled my own as follows: > Is atan with two parameters supposed to behave like atan2? At mp-math.mpxl:167 there is: vardef atan primary x = angle(1,x) enddef ; The MetaPost manual says: The angle operator takes a pair and computes the two-argument arctangent; i.e., angle is the inverse of the dir operator So it looks like "angle" is the function that you want for "atan2".

I was expecting the issue to be something quite simple, but it's actually fairly complicated. Especially considering that the issue only happens with a few printer models, I'm pretty impressed that you managed to find the problem. At least the fix appears quite easy. Seeing that you're modifying the font encoding, could you perhaps reconsider supporting hinting in LMTX? https://mailman.ntg.nl/pipermail/ntg-context/2022/106311.html Even with a high resolution screen, I can still see a difference, and the issue can show up in print too: https://graphicdesign.stackexchange.com/q/5874 I'm fairly confident that these issues are all hinting-related: https://mailman.ntg.nl/pipermail/ntg-context/2022/106874.html https://mailman.ntg.nl/pipermail/ntg-context/2022/105212.html Considering that all of the fonts included with ConTeXt are hinted, it seems like a shame to not include any of that data in the generated PDFs.

I think that MkIV has been frozen since before macOS ARM was released, so I wouldn't be surprised if an ARM version just doesn't exist. I've never used macOS, but if this worked on your Intel Mac, then you can try running the installer via Rosetta instead of running it directly. TeX is so fast that the Rosetta emulation will have fairly little overhead. > LMTX installation, on the other hand, should be successful (the folder > weighs 297.8 MB, as much as the Standalone one should weigh).

Yes, I agree completely here.

The current behaviour doesn't break the unit from the number, but it
does split the scientific notation.
This test file:
\starttext
\hsize=0pt Math: $G = \unit{6.6743e-11 m3 kg-1 s-2}$
\hsize=0pt Text: \unit{6.6743e-11 m3 kg-1 s-2}
\stoptext
gives:
Math:
퐺=
6.6743×
10–11m3⋅kg–1⋅s–2
Text:
6.6743
×
10−11 m3⋅kg−1⋅s−2
which isn't great. In my opinion, the \unit command should be typeset in an
\hbox (or similar) since I can't think of any circumstances where breaking
it would be reasonable.

I don't think that there's any way to do this from within a document
run, so I think that you'll need to use an external program.
> If not, is there a recommended external program that can do it?
But, you can use ConTeXt as the external program here.
Save as "imposition.cld":
local filename = document.getargument("filename")
local pdf = lpdf.epdf.image.open(filename)
local pages = pdf.nofpages
local max = math.ceil(pages / 4)
context.setuppapersize({ "A5" }, { "A3" })
context.setuppaper { nx = 2, ny = 2 }
context.setuparranging { "XY" }
local function insert_page(n)
context.startpagemakeup()
context.filterpages({ filename }, { n })
context.stoppagemakeup()
end
context.starttext()
for i = 1, max do
if i % 2 == 1 then
insert_page(i + 0 * max)
insert_page(i + 1 * max)
insert_page(i + 2 * max)
insert_page(i + 3 * max)
else
insert_page(i + 1 * max)
insert_page(i + 0 * max)
insert_page(i + 3 * max)
insert_page(i + 2 * max)
end
end
context.stoptext()
Then run:
context imposition.cld --filename=document.pdf
where "document.pdf" is replaced by your document name.
I'm not sure if I got your desired output quite right here, but
hopefully you can easily modify the script if something isn't quite
right.

Re: [NTG-context] Apostrophe entity using \xmltexentity is ignored
Hi,
> Has the handling for the apostrophe character entity changed recently?
>
> In the following example, the \xmltexentity for apostrophe is ignored,

> Any ideas on how to fix it?
(see also https://tex.stackexchange.com/a/661002/270600)
There are two different problems here.
1. Typing "'" now gives a straight apostrophe instead of a curly one by
default.
The solution to this is to add
\definefontfeature[default][default][trep=yes]
somewhere near the start of your document. See this thread
https://mailman.ntg.nl/pipermail/ntg-context/2021/104286.html
from last year.
2. ConTeXt ignores the redefinition of predefined entities.
If you run this code:
\enabletrackers[xml.entities]
\xmltexentity{apos}{XXX}
\xmltexentity{lsquo}{YYY}
\xmltexentity{rsquo}{ZZZ}
\xmltexentity{laquo}{«}
\xmltexentity{raquo}{»}
then you get this output:
xml > tex > registering tex entity 'apos' as 'XXX'
xml > tex > registering tex entity 'lsquo' as 'YYY'
xml > tex > registering tex entity 'rsquo' as 'ZZZ'
xml > tex > registering tex entity 'laquo' as '«'
xml > tex > registering tex entity 'raquo' as '»'
xml > core > resolving entity to internal ''
xml > core > resolving entity to internal ''
xml > core > resolving entity to predefined '''
xml > core > resolving entity to internal ''
xml > core > resolving entity to internal ''
xml > core > resolving entity to internal ''
xml > core > resolving entity to internal ''
xml > core > resolving entity to internal ''
xml > core > resolving entity to internal ''
xml > tex > passing entity 'lsquo' as 'YYY' using
'ctxcatcodes'
xml > tex > passing entity 'U+27' as ''' using 'ctxcatcodes'
xml > tex > passing entity 'laquo' as '«' using 'ctxcatcodes'
xml > tex > passing entity 'raquo' as '»' using 'ctxcatcodes'
xml > tex > passing entity 'rsquo' as 'ZZZ' using
'ctxcatcodes'
I know of a bad way to fix this (see the linked SE question), but
hopefully someone here knows of a proper solution.

Babel/ngerman sets left/righthyphenmin to 2/2, but ConTeXt sets those to
3/3 for German. (The English default is 2/3). I don't speak German so I
have no idea which is correct, but you can get the same behaviour in
ConTeXt with:
\mainlanguage[de]
\lefthyphenmin=2
\righthyphenmin=2
\starttext
\showhyphens{Zusammenhang}
\showhyphens{anderswo}
\showhyphens{anderswoher}

Or what am I missing here? I'm not too sure what you're asking here, but Notepad was somewhat- recently updated to handle both CRLF and LF line endings: https://devblogs.microsoft.com/commandline/extended-eol-in-notepad/ But I do agree that the line ending handling seems a little odd. I find it surprising that the buffers internally use CR line endings since no systems in the past 20 years use that. Also, you should probably check to make sure that the results of the file don't depend on the current code page on Windows. Try writing out a buffer from ConTeXt with the following contents: АБВГДЕЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯабвгдежзийклмнопрстуфхцчшщъыьэюя First, run "chcp 65001" before running "context" and record the size of the file written.

The SHA calculation isn't working properly because of a weird newline
issue. Try this:
\setupinteraction[state=start]
\setupinteractionscreen[option={attachment}]
\startbuffer[test]
just a test
and another one
\stopbuffer
\starttext
\startluacode
require("util-sha")
function sha256(str)
return utilities.sha2.hash256(
str:gsub(string.char(0x0D), string.char(0x0A))
)
end
\stopluacode
\def\shabuffer#1%
{\cldcontext{sha256(buffers.raw("#1"))}}
\def\shafile#1%
{\cldcontext{sha256(io.loaddata("#1"))}}
\shabuffer{test}
\savebuffer[test][temporary-αβγ, prefix=no]
\shafile{temporary-αβγ}
\attachment[buffer=test, name=\shabuffer{test}, method=hidden]
\stoptext
You can remove the "\savebuffer" and the "\shafile"; I just kept that in to
show that the two hashes are now the same.

The only real issue that I've had is that it gets fairly slow with documents over a few thousand pages long. Otherwise, it seems pretty fast and stable, and it supports nearly every feature that I tend to need.

You can use "buffers.getcontent" or "buffers.raw":
\startbuffer[test]
One
Two
Three
\stopbuffer[test]
\starttext
\startluacode
require("util-sha")
local content = buffers.getcontent("test")
-- local content = buffers.raw("test") -- same result
local sha512 = utilities.sha2.hash512(content)
context(sha512)
\stopluacode
\stoptext
Depending on what you're trying to do, the "filter" module may be
helpful here.

Re: [NTG-context] Hyphenation in multi-language projects
Hi Steffen,
> … \replaceword should be the correct way for proper hyphenation??
Well I'm not sure if it's "correct", but it seems to work. Based on my
testing, having three subsequent sets of groups ({A}{B}{C}) is converted
to a discretionary. The discretionary hyphen "\-" is equivalent to the
Plain TeX command "\discretionary{-}{}{}", so
\replaceword[hyphenations][steffen][steff{-}{}{}en]
acts just like "steff\-en". TeX won't otherwise hyphenate a word with
discretionaries, so this means that "steff-en" will be the only allowable
hyphenation.

I guess that means I'm volunteering myself :) Similarly to "cont-loc.mkxl", is there some local file that is only read during format generation? Some of my documents use pgf/TikZ and expl3, and loading these during format generation can save quite a bit of time when compiling.

[NTG-context] No error when loading a non-existent module
Hi all, If you load a non-existent module, ConTeXt issues a minor warning, but otherwise proceeds as normal: MWE: \usemodule[doesnt-exist] \starttext Hello world! \stoptext I think that this behaviour should be changed so that a fatal error is issued when a loaded module cannot be found. Plain TeX, LaTeX, and OpTeX all throw an error whenever their versions of modules cannot be found, so ConTeXt is the odd one out here. There are 3 scenarios that I can think of for when you attempt to load a module, but it cannot be found: 1. A module provides some new command "\somecommand" In this case, loading the module will quietly fail, but an undefined control sequence error will be issued whenever you use "\somecommand". This disguises the root problem, which is that the module was never loaded, potentially confusing users. 2. A module changes the layout of a document In this case, the layout of the document would be unchanged by the module. If you're looking at every document, then this would be obvious; however, if you're using some batch processing system, you could unknowingly send out incorrectly-styled documents quite easily. 3. You load a module that provides some command, then never use it This is the only case where the new error would break any documents. However, this case should hopefully be pretty rare since it's pointless to load a module then never use any of its features. Making this change could potentially break some documents that currently work, but I think that this change is worth it, since I'd rather have something break loudly (throwing an error) rather than silently (producing a semi-corrupt document).

Re: [NTG-context] How can I make a Gentoo Linux package for ConTeXt LMTX?
Hi Amano, > Wuh. That's a bit complex. Not really. From a user perspective, all that you need to run is make install From a developer perspective, this is essentially just the base ConTeXt files, a modified texmfcnf.lua, and a fairly basic makefile. > For distribution packages that depend on context for generation of PDF > documents, having context as a system package is essential. I'd say that ConTeXt *is* available in nearly every package manager, via TeX Live. Very very few package managers would have no TeX Live. TeX Live only includes MkIV, the "stable" version, but most users won't notice many differences from MkXL/LMTX, the "experimental" version. By policy, TeX Live only updates its binaries once per year. This would be pretty much unworkable with LuaMetaTeX due to its frequent upgrades. At some point when LuaMetaTeX is stable, the source will be released and almost certainly be incorporated in TeX Live. > And, distribution maintainers can make things work if they understand > TeX directory structure and texmfcnf.lua. Packaging/installing ConTeXt is actually much easier than doing so for other TeX systems. With other systems, you need to fiddle around with fonts and packages, but with ConTeXt, you can pretty much just unpack a few files. Here's a short paper that should give you an overview of how hard packaging TeX can be: https://tug.org/TUGboat/tb34-3/tb108preining-distro.pdf > It comes down to care. If they care and they have installation guide, > they will make it work. I'm not sure who you're talking about here. If you're talking about end- users, then yes, it's pretty simple to install ConTeXt. I personally find ConTeXt much easier to install than TeX Live. If you're talking about packagers, then packaging ConTeXt is no more complex than packaging TeX Live (which of course includes ConTeXt MkIV). The installer documentation for ConTeXt LMTX certainly isn't as detailed as it is for TeX Live, but LMTX is still beta software. If you're trying to say that the ConTeXt developers don't care, then you may be "right" in a sense, but missing the point entirely. There is no one who is paid to work on ConTeXt: all of the developers work on it either as volunteers or to support their own business needs. The current installer works for them and for many other users. This isn't to say that they don't care about the users, but rather that they are unlikely to spend much time making a package for a fairly unpopular distro where the official installer already works. > On Sunday, August 21st, 2022 at 7:13 PM, Michal Vlasák > wrote: Hi Michal, > > I prepared a proof of concept, that I am ready to take down immediately > > at Hans' request, since I don't handle license information properly, and > > texmf-context is stripped down (just so that the downloads are not too > > big for proof of concept). > > > > https://github.com/vlasakm/context That's quite impressive! > > There is documentation about how it can be used.

Well packaging the files into .rpm/.deb isn't really a bad idea; what's bad is the weird modifications that distros make, plus the fact that nearly every distro delays updates by quite some time. I generally agree that installing TeX straight from the source is better, although I can see why some users prefer to install from their distro repos.

Right now, the only files available for download that I'm aware of are the latest versions. This is problematic from a reproducibility standpoint, since if you have multiple people, say, writing a large textbook, it would make sense that they wouldn't want to upgrade their systems constantly in case something breaks. These people can easily just avoid upgrades, but if someone new joins the team, they can only download the newest version. However, that won't necessarily match the older version that everyone else has, which can lead to problems. Having older versions available would also help in the case of major short-term regressions, since users would be able to (manually) downgrade to an older version if necessary. An easy solution to this would be the following: instead of overwriting the whole "/install-lmtx/" tree on every update, you would install all the new files to something like "/install-lmtx-2022-08-07/", then have "/install-lmtx/" be a symlink to the latest "/install-lmtx--MM-DD/". I don't think that this would be very hard to implement from a technical perspective, and the only downside that I can think of would be extra disk space used. This is a fairly common implementation among other software. One other solution would be to have "dl.contextgarden.net" mirror a zip/binary combo once every few months or so. These would often be out of date, but they would provide a stable archive that would be useful in cases like this. This is just a suggestion though; it's not something that I personally need, although I see how it could be potentially valuable for others.

After playing around, I found that this is stored in ".index". I'm able to write to this value just fine, but whenever I
read it I get an error.
This minimal example:
\starttext
\setbox999=\vbox{\hrule width 10pt height 10pt}
\startluacode
local insert = node.new("insert")
local rule = tex.box[999].list
insert.list = rule
insert.index = 4
node.write(insert)
\stopluacode
\stoptext
works perfectly, but this example:
\startluacode
local insert = node.new "insert"
insert.index = 4
print(insert.index)
\stopluacode
gives this error message:
In \insertmode 2 you can't use zero as index.
I suspect that this is a bug, but I may just be doing something wrong.

Inserts always felt a little hacky in TeX, so I think that the new

Perfect! "tex.getinsertcontent" does exactly what I need.
Really minor, but I would expect that
tex.insertcontent[4] =

would be exist and be equivalent to
= tex.getinsertcontent(4)
tex.setinsertcontent(4, )

I don't think that that will work in this case. I'm doing most of the
work in "pre_output_filter", which is after all of the insert nodes have
been removed from the page and put into their respective boxes. And I
can't postpone setting any inserts until then because TeX needs to know
their height for when it breaks the page. I don't really like how I have
to move the footnotes, but I can't find any better way of doing things.
If you're curious, most of the insert code is in these two functions:
https://github.com/gucci-on-fleek/lua-widow-control/blob/2bca90/source/lua-widow-control.lua#L612-L669

Re: [NTG-context] How can I make a Gentoo Linux package for ConTeXt LMTX?
Okay, I'm seeing a few separate issues here. 1. Gentoo expects to compile everything from source. This isn't an option here since LuaMetaTeX doesn't have any source available (yet). So for the time being, you'll need to use the provided binaries. These support pretty much every architecture, so this shouldn't really be a problem. 2. You want to install ConTeXt LMTX system-wide. This is doable with the standard Linux installer script. Just make sure to run the script as root and install the files in /opt/context. This is what I've done on my system, and it works quite well. $ ls -l $(type -p context) lrwxrwxrwx. 1 root root 10 Jul 28 00:33 /opt/context/tex/texmf-linux-64/bin/context -> luametatex* 3. You want to install ConTeXt without any network access. The easiest way to do this would be to install on a system with internet, then just copy over the files. If you want to use the "original" installer files, it shouldn't be impossible, but probably not too easy either. (All steps below are untested) The platform-independent stuff is all in one big zip, located at: http://lmtx.pragma-ade.nl/install-lmtx/texmf-context.zip Unzip this file as "/tex/texmf-context/". Then you also need to download all of the binaries. You will need to download all of the paths listed in this file: http://lmtx.pragma-ade.nl/install-lmtx/tex/texmf-linux-64.tma All of those files need to be placed in "/tex/texmf-linux- 64/bin". Then to finish installing you'll need to run "mtxrun --generate" and "context --make". There are probably a bunch of other steps that I'm missing, but this should get you close. Again, probably easier to just use the regular installer. 4. ConTeXt is really picky about texmfcnf stuff. This is an issue that I've had too: https://github.com/latex3/l3build/issues/232 Pretty much any modification of anything texmfcnf-related with ConTeXt will completely prevent it from running. There's a thread discussing the problem (but with no real solutions) here: https://tug.org/pipermail/tex-live/2020-September/046099.html And a Wiki page here: https://wiki.contextgarden.net/Custom_Configuration I agree that this texmfcnf stuff makes it really difficult to install or use ConTeXt with any kind of custom paths. Does anyone know how to properly configure a texmfcnf with custom paths? Hopefully this is of some help. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___
[NTG-context] Accessing inserts from Lua in LuaMetaTeX
Hi all, I'm trying to manipulate some inserts from Lua in LuaMetaTeX, and I'm having some problems that I'm not having with LuaTeX. First, how do I get an insert's class/type from the "insert" nodes on the page? With LuaTeX, the insert's class/type is the same as the subtype of the "ins" nodes, but the subtype of the "insert" nodes is always zero in LuaMetaTeX, so I'm not sure how to get the class/type. Second, how do I get the head of the insert box from Lua? With LuaTeX, from TeX you would use "\box" and from Lua you can use "tex.box[]". With LuaMetaTeX, you use "\insertbox" from TeX, but I'm not sure how to get at the insert box from Lua. The context for both of these is that my module lua-widow-control sometimes moves a line containing footnotes to the next page, so I need to do some surgery to make sure that the "footnote marks" stay with the "footnote text". This is tricky but doable with LuaTeX, but I can't seem to get it to work with the new inserts in LuaMetaTeX, hence the above questions.

[NTG-context] Can't manipulate glue added by tex.preparelinebreak
Hi Hans,
The new tex.preparelinebreak is great (thanks again), but I can't seem
to figure out how to manipulate the parfillskip nodes that it adds.
MWE:
\newbox\testbox
\startluacode
function test(head)
if head.id ~= node.id "par" then
return head
end
new_head = node.copylist(head)
tex.preparelinebreak(new_head)
local parfillskip = node.tail(new_head)
inspect(parfillskip) -- Confirm that this really is a parfillskip
parfillskip.stretchorder = 0
parfillskip.stretch = 0
local broken = tex.linebreak(new_head)
tex.setbox("global", "testbox", broken)
return head
end
\stopluacode
\starttext
{\dorecurse{209}{Hello }\par}\page
{\parfillskip=0pt\dorecurse{209}{Hello }\par}\page
{\ctxlua{nodes.tasks.appendaction("processors", "after", "test")}
\dorecurse{209}{Hello }\par}\page
\box\testbox
\stoptext
I would expect that pages 1 and 3 would be identical, and that pages 2
and 4 would be identical. However, page 4 is the same as pages 1 and 3,
which isn't what I'd expect. I can do a similar idea in LuaTeX/MkIV and
get the expected results, so I'm not too sure what I'm doing wrong here.
I'm probably just missing something obvious, but I'm not too sure what.
Any ideas?

I would like to show them a good result. I've been using Firefox (and pdf.js) as my PDF viewer almost exclusively for the past ~2 years, and I've been using ConTeXt LMTX for about the same amount of time. I haven't noticed any font issues, so I suspect that this issue is system-dependant. I've mostly been on Windows for the past few years, but I'm now on Linux, and I haven't noticed any issues with either. > I have no idea if the difference is the cause of the bad display. > > Luckily chrome based browsers shows the fonts without any flaws. Ok, random guess time (so I may be waay off here): I think that this is a hinting problem. The TeX Gyre fonts are all professionally hinted, so what might be happening be that when ConTeXt is subsetting the fonts, it is removing all of the hinting information, while LibreOffice is keeping all of the hints. I've opened PDFs from ConTeXt and LibreOffice in FontForge and the hints are still there, so I don't think that this is the case, but maybe? The hinting format is also wildly different between Type 1 and CFF/OTF, so maybe there is just a bug in one of the font renderers. Chrome uses an internal backend to render all of its text, but Firefox uses system-dependant backends (I think). Most renderers these days will autohint unhinted fonts using an embedded FreeType so that they still display somewhat-well. You can adjust the "hinting strength" in FreeType, which I would guess would usually be set to the maximum. So LibreOffice includes the font hints and things display fine, and Chrome uses a bundled FreeType with maximum hinting so things display fine. Firefox on Windows would need to bundle its own FreeType since there isn't a system one, and it renders fine in my experience. But Firefox on Linux would just use the system FreeType. I think that you are on Linux (?) and the default in Linux is for minimal/no hinting. Now, I've specifically enabled maximum hinting on my system, and I'm not seeing any problems with rendering. If you're using Gnome, can you try enabling "full" hinting in Gnome Tweaks, reboot, then test again? No idea how to configure this with other DEs, but I'm sure that it's possible. Another related guess is that older versions of FreeType maybe had a bug with parsing/displaying hints. I think that Chrome bundles its own FreeType which would be recent, but if you're using Firefox on Linux, it is probably using the system FreeType library. If you're on an older LTS distro, then the system FreeType may be really old and buggy. If you're using macOS, I can't really help you too much except for to say that text rendering on macOS is usually pretty bad unless you have a really high resolution screen. So those are my random guesses. Maybe one of them is helpful somehow. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___

Re: [NTG-context] upload
This is because you need to pass a list that conforms to what the
builder expects and the callback that you use doesn't do that for you
(after all, it also gets hbox content).
Isn't "processors/after" the same as "pre_linebreak_filter"? I thought
that only "hpack_filter" gets \hbox content? Anyways, my actual function
has this guard at the very start:
if (head.id ~= par_id and context) or -- Ensure that we were
actually given a par
status.output_active or -- Don't run during the output routine
tex.nest.ptr > 1 -- Don't run inside boxes
then
return head
end
so I think that I'm only processing actual top-level paragraphs here.
There is no 'callback sequence handler' for the par builder (currently i
see no need for it, also given the extra overhead involved) but this
what what you can do:
\startluacode
function builders.paragraphs.constructors.methods.preroll_a(head)
local result, info = tex.linebreak(head)
tex.prevdepth = info.prevdepth
tex.prevgraf = info.prevgraf
return result
end
function builders.paragraphs.constructors.methods.preroll_b(head)
local result, info = tex.linebreak(nodes.nuts.copylist(head))
inspect(info)
return true
end
\stopluacode
\defineparbuilder[preroll_a]
\defineparbuilder[preroll_b]
\starttext
\setmainparbuilder[default] \input tufte \par \input tufte \page
\setmainparbuilder[preroll_a] \input tufte \par \input tufte \page
\setmainparbuilder[preroll_b] \input tufte \par \input tufte \page
\stoptext
I think that that code is for replacing the linebreaker entirely, like
with using "linebreak_filter"? My goal isn't to replace the linebreaker;
I just want to be able to inspect the paragraph before it is broken,
without modifying anything.
What I'm trying to do *very* roughly looks like the following:
paragraphs = {}
attribute = 1234
function pre_linebreak_filter(head)
if head.id ~= node.id"par" then
return head
end
local nat_node, nat_info = tex.linebreak(node.copylist(head))
node.freelist(nat_node)
local long_node, long_info = tex.linebreak(
node.copylist(head), {looseness = 1}
)
if long_info.prevgraf == nat_info.prevgraf + 1 then
table.insert(paragraphs, long_node)
end
return head
end
function post_linebreak_filter(head)
node.setattribute(head, attribute, #paragraphs)
node.setattribute(node.slide(head), attribute, #paragraphs)
return head
end
function pre_output_filter(head)
if tex.outputpenalty ~= tex.widowpenalty then
return head
end
-- Pick a paragraph from `paragraphs` somehow
-- Replace that paragraph on the page with the one
-- from `paragraphs`
-- Move the last line of the page onto the top of
-- tex.lists.contributehead
return head
end
(The full implementation is in the module "lua-widow-control" on CTAN,
TeX Live, and modules.contextgarden.net, or directly at
"https://github.com/gucci-on-fleek/lua-widow-control/blob/master/source/lua-widow-control.lua;.
It's pretty long though, so I'm just trying to summarize here.)
This works pretty well with Plain LuaTeX, LuaLaTeX, OpTeX, MkIV, and
MkXL before the latest upload, but something broke with the latest
upload in MkXL. I understand that I'm mucking around with volatile
interfaces, and I have no problem making a bunch of changes whenever the
engine/format changes; the problem is that I'm not too sure what changed
in the engine, so I don't know what I need to change in my code.
On the to do is a to add a 'prepare' helper that adds
the mandate nodes (par fillers etc)
Maybe that's all that I need? If that's the case, I have no problem
coding my own "prepare helper" if you think that it'll be awhile before
you get around to it; the problem is that I'm not entirely sure what
nodes I would need to add. These new nodes aren't added until after
"pre_linebreak_filter", and they're gone after the linebreaker runs, so
I can't inspect a "regular" paragraph to see where these nodes belong.
but even then one has to be careful
where linebreak hackery is applied.
Oh yes, I'm well aware :) Earlier versions of my module would silently
eat entire paragraphs, which was very not good. Luckily that problem is
fixed now.
And finally, thanks for all your work with LuaMetaTeX. This new engine
is quite nice to work with and has some pretty cool new features.
Thanks,

Re: [NTG-context] Malfunctioning of syllabic partitioning of words in Spanish
I am writing a document in Spanish and I notice that the syllable partitioning of words does not conform to the rules of the language. And so, for example, the word "limitarse" is partitioned as "lim-itarse" (the correct one is "li-mi-tar-se"), "colores" as "col-ores" (instead of "co-lo-res"), "abstenerse" as "absten-erse" (and it should be "abs-te-ner-se"), etc. Make sure that you set up the language correctly. Using this test file (on today's new upload): \language[es] % Needed for Spanish hyphenation \starttext \hsize=0pt % Hack to force hyphenation limitarse colores abstenerse \stoptext I get: li-mi-tar-se // co-lo-res // abs-te-ner-se I don't know any Spanish, but using your test words, I think that these are the expected results. Using the "pattern" script, I get slightly different results, but it still seems correct to me: $ mtxrun --script pattern --hyphenate --language=es limitarse [...] mtx-patterns| es 3 3 : limitarse : limi-tarse $ mtxrun --script pattern --hyphenate --language=es colores [...] mtx-patterns| es 3 3 : colores : colo-res $ mtxrun --script pattern --hyphenate --language=es abstenerse [...] mtx-patterns| es 3 3 : abstenerse : abs-te-nerse If adding "\language[es]" to your document doesn't help, I believe that there are a few Spanish speakers on the list who will know much more than I do about setting up the hyphenation. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
Re: [NTG-context] upload
Hi,
With the latest upload, "tex.linebreak" doesn't return an "info" table.
When running this code:
\startluacode
function test(head)
local new_head, info = tex.linebreak(node.copylist(head))
print(head, type(head), info, type(info))
if info == nil then
print "!!! info is nil !!!"
end
return head
end
nodes.tasks.appendaction("processors", "after", "test")
\stopluacode
\starttext
Hello!
\stoptext
with the latest upload I get (also note the small typo in "rigthfill"):
luatex warning > linebreak: no [ leftinit | rightinit | leftfill |
rigthfill] expected
2353 : par vmodepar> userdatanil
nil
!!! info is nil !!!
2299 : glue userskip> userdatanil

but with live.contextgarden.net I get:

Re: [NTG-context] "pragma-ade.com" is now a domain parking page
Well, we must change a lot of dead links on the wiki now. Taco, can you automate it? Otherwise I’ll start... I do not know of a clean way to automate that. It may be possible, but then it is outside of my knowledge set. So yeah, by hand. This might work https://wiki.contextgarden.net/Special:ReplaceText but I don't have the permissions to use it. I have no idea if it will work, but it looks like both of you (Hraban and Taco) are administrators and thus have requisite permissions to test it. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
Re: [NTG-context] "pragma-ade.com" is now a domain parking page
Hans had been complaining about networksolutions not allowing him to move the domain away from them, so I guess this was to be expected. indeed, and transfer is pending for ages now ... looks liek they don't like to transfer They only have 5 days to respond to a transfer request. If it's been longer -- which it presumably has been -- you can file a complaint with ICANN, which should hopefully push them to complete the transfer. https://www.icann.org/en/system/files/files/transfer-complaint-24aug16-en.pdf Even if it's expired, you should still be able to transfer it: https://www.icann.org/resources/pages/name-holder-faqs-2017-10-10-en (#11) The WHOIS info says that the domain doesn't expire until 2023-06-28, so I'm not too sure what's going on here. make me wonder if we should just ditch that domain and stick to the nl one only, saves money too There are lots of links around the web to "pragma-ade.com". It might be a good idea to phase out the .com and have all of the pages redirect to the .nl, but I'd say that it's probably worth the ~$15/year to make sure that pragma-ade.com isn't used to host spam/porn/malware. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

When I go to: https://www.pragma-ade.com/ I get a page that says: pragma-ade.com expired on 06/28/2016 and is pending renewal or deletion. followed by some advertisements.

[NTG-context] Tagging corrupts URLs in bibliographies
Enabling PDF tagging corrupts the URLs displayed in bibliographies.
MWE:

\usebtxdefinitions[apa]
% \usebtxdefinitions[chicago]

\nocite[article, advancedonline]

I think that APA and Chicago are the only styles that display URLs in
the bibliography, but there may be others that I'm missing. There's a
patch at the end that seems to fix things for me, although there's
likely a better solution.

[NTG-context] Odd behaviour with Plex typescript
If you load the Plex typescript, a spurious space is added on the first
switch to another font, messing up any alignment. This doesn't happen
with any other fonts; only with Plex.
MWE:

\setupbodyfont[plex]
\starttext
\section{A}

I was able to fix this by removing the space immediately before the "%"
on line 136 of "type-imp-plex.mkiv", changing it from this (original):
\definefontfeature[plexwideneddefault][default][extend=\luaexpr{1/0.85}] % An
odd floating point number to correct monospace.
to this (fixed):
\definefontfeature[plexwideneddefault][default][extend=\luaexpr{1/0.85}]% An
odd floating point number to correct monospace.
I'm pretty sure that TeX is ignoring spaces at this point, so I have no
idea why this issue exists or why the fix works.
