\stopregister [index] [B]

(Watch the [A] vs {A} usage where [A] is the label used for matching the
potentially weiord nested start/stop ... maybe we need different aliases
for these, like \fromregister and \toregister.)

Since I've become an expert on tuc files since yesterday (ha!): if I compare the tuc from
a mkiv and a mkxl run, I see that mkiv produces an entry ["lastrealpage"]=9 in
the references table, mkxl doesn't. This appears to be the relevant bit, and it is
connected with the replacement of realpageno by c_realpageno in line 638 of strc-reg.lmt
references.lastrealpage = texgetcount(c_realpageno)
Let's seen if we can make Thomas more of an expert as he's zooming in on
the issue:
extendregister {
metadata = { name = name },
references = { abel = label },
}
Let me know if you't see it.
Possibly related: I noticed last week that mkxl does not update the legacy
counter \pageno any more for every page.
i'll check it

[NTG-context] Re: Why don't footnotes appear in floats or figures?
On 4/22/2024 2:45 AM, Joel via ntg-context wrote:
I'm three days out from sending my work to an editor, and found some
serious problem: many footnotes just aren't rendering.
I have a history text that uses ConTeXt-SBL for the citations, as such,
it has lots of footnotes. Sometimes the footnotes are just in the main
text, but sometimes also in figure captions, inside floats, inside
tables that are inside floats, inside tabulations inside floats, etc.
What I find alarming is it is frequently not rendering all of the
footnote messages at the bottom of the page. The actual footnote number
within the body is rendered, but no number is listed in at the bottom of
the page. So I might see a list of footnotes, for instance, on page 1, I
only get footnotes 1, 2, 3, 5, and 6, but 4 was mysteriously skipped.
---
1 message
2 message
3 message
5 message
6 message
After a lot of trial-and-error and checking logs and checking my BibTeX
files for errors, running everything through BibTex Tidy, etc., and
failures to make a minimum working example, I found a single pattern:
If the footnote marker appears on the SAME page as the footnote text, it
has no problem rendering the footnote. But, if ConTeXt decides to move a
float a page or two later on--as it frequently seems to do---such that
the footnote marker and footnote text at bottom of page should be on
DIFFERENT pages, the footnote message at the bottom of the page won't
render.
I've seen some 2+ year old mailing list posts suggesting ConTeXt might
have issues with footnotes; they appear to be similar to my issue--is
that still a problem? Is there a fix or workaround? Old fixes I could
finding in the mailing list don't seem to work with current versions of
ConTeXt anymore.
you need to consider the complications of such notes ...
- tex needs to take the notes into account when determining a page break
- it does so by the insert mechanism
- when floats can't be placed they also become inserts (top and bottom)
- when there are inserts in inserts th eproblem becomes more complex (so
notes inside floats)
- in traditional tex deeply burried inserts disappearm less so in lmtx
There are things that are hard to get right. This works:
\startpostponing
\startplacefigure[location=here,title={test \footnote{oeps 1}}]
\blackrule[width=1tw]
here
\footnote{hello 1} and
\footnote{hello 2} and
\footnote{hello 3} done
\stopplacefigure
\stoppostponing
\dorecurse{10}{\samplefile{tufte}\par}
Because here the inserts (notes) will migrate but even then one can get
them out of order (unless we renumber, which then is sensitiev for
oscillation).
I occasionally wonder if top floats could be done more directly but
bottom notes still would have an out-of-sync problem

(1) I tried placing a table inside a startitemize environment, as
instead of it not compiling, it left a message in the document warning
that wasn't supported.
(2) In another case, I had an image that ConTeXt couldn't find, as I
mispelled the filenmame, and it fully compiled and made a PDF, without
me noticing.
(3) Or maybe in some case, a font couldn't be found for a specific
character, so a single character in the file isn't displaying.
Those are just some examples; I intended for something to be printed
on the PDF, but it isn't showing there.
Since a document of this size will have a lot of messages, is there a
way to adjust the settings, from "show everything" to "show some" to
"show only serious errors"? Or maybe to use > to send the errors to
another file for careful study? (using Linux if that matters)
You can enable trackers like
\enabletrackers[figures.*]
But that just gives more log messages for debugging.
You get the list of all trackers with:
context --global m-trackers.mkiv
For your use case, directives are more helpful, like
\enabledirectives[logs.errors=*] (i.e. break at every error)
AFAIK that just handles missing characters, references and modules ATM,
but this information might be outdated.
You get all directives with
context --global m-directives.mkiv
often the log files has some summaries at the end

I agree. It sounds the same as "we're not msword" or "we're not google

is that they use the tex language / ecosystem.)

Found it - and I'm embarrassed to say it was in my own environment file,
not in the lmtx distribution. I have a Lua function that prints
information about the computer model and the operating system into a
layer. Unfortunately, there was an "elseif" in there somewhere which
should catch exceptions (such as a raspberry pi), but instead of
concatenating the relevant return values to display in the layer, I had
a ' context (" on ")' in there (probably for debugging) which I forgot
about.
Sorry for the noise - I was getting too sophisticated for my own good...
No problem, is it a rpi 5? If so, how does that one perform?

well, tagging ...
Of course.
But you asked for wanted accessibility features:
sure.
We have \pdfbackendactualtext{visible}{alternative}, can we get
alternative text (ActualText) for images?
Not automatically, of course (if someone wants AI descriptions they can
implement a module), just as a keyword in \externalfigure?
we can add a description option that then can eb used in the wrapper
(not that it helps much to make an image accessible)
btw, someone showed me what this acrobat liquid mode does to a document
... the fact that one has to apply 'ai' to a document is a bad omen and
makes one wonder ... but anyway, big tech, big money, etc so ... (after
visiting a typesetting museum today one again realizes that a few
decades from now one will look back in a certain way, not all is progress)
one thing we need to keep in mind is that as soon as 'obsolete' and 'not
to be used' enters descriptions (which kind of contradicts the
flexibility of sofware) one can also wonder how older documents can ever
match a standard; i often get the impression that instead of some
thinking ahead we end up adapting to what can't be done or what went
wrong (and calling something a standard can then be a way to obscure)
anyway, one way or the other we will cope (and it depends on user demand
which in turn depends on organizational demand)

Hi everyone,
I'm a bit puzzled because I usually don't get an em-dash when I type
tree hyphens. If I use the command \emdash, no problem but when I use
the hyphens some days it works... and somedays I see three small
hyphens.
I tried it on overleaf and of ContextOnWeb with the same
inconsistency. If I create a new file it usually works right; but
when I overwrite an existing file subtituting a hyphen for three
where the dash should be I sometimes get it right and sometimes wrong.
It is not the pdf viewer since I get good or bad results in all, the
overleaf pdf preview tool, the context on web preview tool and the
mozilla integrated pdf viewer.
Am I missing something on the use of this ligature? (the question is
just out of curiosity, since I plan to create a command that adds a
hairspace after or before the dash, since I don't like it to stick to
some letters like "o".
Generally, “we” try to reduce active characters as much as possible,
that’s why -- and --- usually /don’t/ produce en or em dashes. You can
activate these ligatures as a font feature though (AFAIR
"latexhyphens", can’t find it…).
The name of the option has changes a few times and the current setting
is textcontrol=collapsehyphens.
Some editors and some fonts do automatical replacements.
In this case it could be the wrong symbol in the document, there are
many dashes in unicode which look similar in the input and output files.

\starttabulate[|T]

\stoptabulate
\stopbuffer
\getbuffer
\setupbodyfont[pagella]
\getbuffer
\stoptext
detail: it is not a real fontfeature (as tlig in mkiv) but implemented
differently with a bit more control, so we have
\nohyphencollapsing
\dohyphencollapsing
etc too as control options. These collapsed hyphens are also configured
as valid hyphenation chars.

And when would you suggest what?
A float I’d use only if I need caption/numbering or the floating feature.
When I tried line correction, it never helped; probably I used it wrong
(e.g. around section titles).
linecorrection is older, textdisplay newer and both are mainly meant to
position boxed content (like images) in a way so that spacing looks
acceptable ... they are vboxes with spacing around them so not meant for
e.g. section heads or whatever text; it's for images, framed stuff,
maybe bTABLE etc

Hi Hans and Mikael,
Thanks for the new module math-goodriddance !
Indeed there are many mathematicians who are going to use the
\goodriddancemath command, and no doubt they are going to thank you,
even if they are very shy to come out.
Moreover this command can be used by people who want to transform the
output PDF into an audio file, because for instance the following
\usemodule[math-goodriddance]
\goodriddancemath
\starttext
\startformula
\int_{0}^{\pi} \sin(x)\dd x = 2.
\stopformula
\stoptext
gives
integral from 0 to 휋 , of sin of 푥 d 푥 equals 2
you cna be more ambituous:
\im { C \of (\openinterval{a,b}) \neq C^^2 \of (\interval{a,b}) \neq
C^^2 \of \interval{0,1} \neq C\of(\Omega) \neq 풞 \of (\Omega)}
or
\dm {u\of(b)-u\of(a)=\lim_{n\to+\infty} \parenthesis{f(x__1)\Delta
x__1+f(x__2)\Delta x__2+\ldots+f(x__n)\Delta x__n}}
so we can really get rid of a lot of math
as one can see in the attached output which is very useful for the blind
using an audio software.
yes, although unfortunately unicode never bothered to add some handy
stuff for that (while if did for other comparable things) but we'can get
around that
I now assume that you are willing to come up with the french
translations (that then can be validated by Alan). Do we actually have
serious german context math users, as I wouldn't trust Hraban and Thomas
on doing this?

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

We're done with math. After years of active development, Mikael and Hans have
decided to quit working on math, and concentrate on \METAPOST\ and handing over
to the next generation instead. We lost our user to the way more popular
alternative (frozen in stone standards). Also, we had it with suboptimal math
fonts, Unicode math not getting improved, MathML constantly being changed,
browsers dealing with math differently every few years, math archives getting
polluted with tons of useless tagged math.
There are other motivations, like the European union imposing strict rules with
respect to accessibility in educational content management systems, and Dutch
schools trying to get rid of math in favor of simple calculus, if at all. This
is
why the next iteration of the engine will no longer have a math engine:
MathLessTeX. Of course, in the beginning \MLTX\ will be compatible with \LMTX,
because we owe that to the users and we need to prototype the new engine anyway.
In order to get an idea of how we will get rid of the disturbing formulas, you
can load the module:
\starttyping
\usemodule[math-goodriddance]
\stoptyping
Until becoming the default setting, the command \typ {\goodriddancemath} will
bring you into \MLTX\ mode while \typ {\badriddancemath} will bring you back to
the obsolete \LMTX\ mode. Like:
\startbuffer
\usemodule[math-goodriddance] \goodriddancemath
Who wants to solve the equation \m {x + 1 = 4} or deal with the function \m {x
\mapsto
\root [3] {x}}, when we have AI around the corner to help us out with simple
and silly
things like the Pythagorean theorem: \m {a^2 + b^2 = c^2}, or even with more
advanced
math like geometric series: \m {\sum_{k = 0}^{+\infty} x^k = 1/(1 - x)}?
We will not support complicated nonsense stuff like:
\startplaceformula
\startformula
F__{1}{2}(a,b;b;z) = (1 - z)^{-a}
\stopformula
\stopplaceformula

The image can't be more than \textwidth wide, and can't ever be more than
1.2\textwidth high.
The problem I am getting with this code, and it does seem to be limiting the
images to be not bigger than those two dimensions above, is some of the images,
for reasons I can't understand, are appearing really tiny and aren't scaling up
to fill as much space as is possible. I can't explain why this is
happening--the images themselves are very very high resolution.
Is there any way to modify the code to make sure the image stretches up to be
the biggest it can, without exceeding the sizes I've listed?
Hi Joel,
AFAIK, if you don’t set at least either height or width, ConTeXt uses the
image’s resolution setting to calculate its size, and that is often useless.
(Maybe there’s also something wrong with ConTeXt’s max width/height, I don’t
know; I’m still planning to carefully check all options of image processing…)
You could try if "factor=fit" or "factor=max" yields the results you want.
As Hraban says, you only need to set one of height or width and Context works
out the other.
For your case I think you just need width=\textwidth, so
\externalfigure[#1][frame=on,width=\textwidth,maxheight=1.2\textwidth]%
where maxheight imposes the height size limit you mention.
If you still have problems with tiny images then I suspect that is a different
issue - something to do with the image file and the metadata about the image
size maybe? If you can share an affected image then perhaps start another
question with an MWE and upload the image somewhere.

Am 12.03.24 um 23:59 schrieb seyal zavira:
You are correct. when i convert this svg to pdf via inkscape it works
like a charm.
But what is standard way of including an svg file with context if we
want to inkscape render the images?
\externalfigure[smile]
without any other settings, but inkscape must be callable on the command
line (which doesn’t work for me on MacOS any more, must investigate…).
\startMPcode
draw lmt_svg [ filename = "smile.svg"]
\stopMPcode
Now gives the attached but it took me a while to figure out what works.
An inkscape export adds for instance something (globally applied) that
is not in the svg file (which actually derived from tiger.svg as
mentioned in the file).
To be honest this is a horrible file and a good example of making things
more complex than needed (probably common in wysiwyg applications),
although we already had the machinery in the mp/pdf converter.
The biggest issue here is that one has to put some constrants in place
order to make it work in e.g. sumatra (mypdf) and acrobat (which here
actually does weird erratic things when I play with another test).
As with much complex svg, browsers also differ in interpretation o fsome
features so it's hard to figure out what to do when there are
conflicting demands. (Pointing to something that works tomorrow doesn't
mean it worked when we tried to implement something yesterday.)
For Hraben - who mentioned it - i also added support for group opacity
and transformed shades.
In the process I tried a few inkscape options (pdf export) but some
produce faulty files (with missing stuff) so i guess we have a complex
situation in general. That said, as long as one sticks to reliable and
clean code (plain svg) it should mostly work out.
Text is another matter because svg dropped glyph support so now
everything has to go through font features which in turn means that if
one uses svg as output format one has to specify every character with
possible abuse of a substitution feature that accesses it. So that is no
longer a real interesting option, unless of course one exports all text
as curves, just to be sure.
(I will extend general text suport but it will always be suboptimal but
then, svg is not a long term archival format anyway.)
No upload yet as i also want to do some cleanup,
ps. For metapost lovers, here is some of the trickery used:
\startMPpage[offset=1ts]
draw image (
fill (unitsquare xscaled 10cm yscaled 4cm)
withcolor svgcolor(0.5,0,0)
;
registerluminositygroup ("test") (
fill (unitsquare scaled 2cm) shifted (1cm,1cm)
withshademethod "circular"
withshadecolors (.6,.1)
) ;
applyluminositygroup ("test") (
fill (unitsquare scaled 2cm) shifted (1cm,1cm)
withshademethod "circular"
) ;
draw luminositygroup (
fill (unitsquare scaled 2cm) shifted (4cm,1cm)
withshademethod "circular"
withshadecolors (.6,.1)
) (
fill (unitsquare scaled 2cm) shifted (4cm,1cm)
withshademethod "circular"
) ;
draw luminosityshade (
(unitsquare scaled 2cm) shifted (7cm,1cm)
) (
withshademethod "circular"
withshadecolors (.6,.1)
) (
withshademethod "circular"
) ;
) ;
\stopMPpage
Not that intuitive and a bit ugly deep down but it works (there was no
need to extend mp btw as we already have graphic grouping in the engine).

I don't see that it would hurt anything, even if it doesn't give complete
cmyk support.
We provide
\pgf@context@registercolor
\pgf@context@registergray
\pgf@context@registerrgb
\pgf@context@registercmyk
in colo-ini that hook into the context color mechanism so be careful
with patches. I'm not going to spend time on other solutions that can

[NTG-context] update
Hi,
Todays update has a fix for the compact mode slant interference (as
explained by Wolfgang a few days ago). Hopefully that works out well.
We (MS and HH) also managed to make curve detection more accurate (the
decision routine that is responsible for straight lines in the MP
output) so that extreme paths with control points way beyond reasonable
still produce the right output (before we could get a wrong bbox due to
clipping the curve in the backend). One can actually also force "always
curve" with "withcurvature 1" (more variants might follow) but that is
more or us to have a test option. Curvature detection is mostly a pdf
efficiency feature and normally users should rely on the default to work
okay.
Other new mp features are relative and absolute points which makes it
possible to define paths in a turtle graphics way (a bit like hlineto
and vline in postscript), a native "--" operator (equivalent but
somewehat more efficient on huge generated paths). The luametafun manual
has a chapter on paths that describes some of this.
Yet another new feature is "firstcontrol" and "secondcontrol" that is an
addendum to controls that makes both control points the same when only
one is given.
Finally there is a fix in mp where some directions, think { dir 120 },
gave the wrong result due to sign swapping (so it was seen as { dir 200}
or { dir -60 }) as side effect of negative zeros fed into tan2. This
became obvious when MS reprocessed a graphic, as last year we switched
from scsled (no bug) to double (long time bug exposed). (The bug is also
present in LuaTeX double/binary mode but it will be fixed there too.)
The rest is not (yet) worth mentioning,
Hans

The results happen when you use compact mode and is a result of
\glyphslant which keeps the value of the italic style even when you
switch back to the upright style.
Many thanks for your explaination,
using the low level commands
\glyphscale
\glyphxscale
\glyphyscale
\glyphslant
\glyphweight
directly can have side efects when at an outer level these are also
set, so you need to accumulate, like
\starttext
test {\glyphscale 2000 test \glyphscale \numericscaled1.2\glyphscale
test} test
test {\glyphslant 500 test \glyphslant \numericscaled2.0\glyphslant
test} test
test {\glyphweight 100 test \glyphweight\numericscaled2.0\glyphweight
test} test
\stoptext
The problem is that compact mode uses them to apply the slanted feature
without any manual use of the commands from a user.
\enableexperiments[fonts.compact]
\definefontfamily[mainface][rm][TeX Gyre Termes]
[it={style:regular, features:{default,slanted}},
sl={style:regular, features:{default,slanted}}]
\setupbodyfont[mainface]
\starttext
\startstyle[style=italic]normal {\em emphasized} normal\stopstyle
\stoptext
The only way to mask the effect is to create a new fontfeature with the
minimum slant value and apply it to the upright style.
\definefontfeature [unslanted] [slant=0.001]
\definefontfamily[mainface][rm][TeX Gyre Termes]
[features={default,unslanted},
it={style:regular, features:{default,slanted}},
sl={style:regular, features:{default,slanted}}]
ok, i'll fix that (build is down so no update)

With current latest (2024.02.27 09:21), LuaTeX gets boldened and slanted

wider will not mix with boldened-30 [even when specified]).
For some reason, LMTX from current latest cannot get slanted and
boldened-30 (but it mixes the inherited wider feature in all fonts).
This began to behave differently in latest from 2024.01.08 11:23 (which
is my next version after the one from 2023.09.26 18:19).
Could anyone confirm the issue?
accumulating these effects is dependent on how the features that you use
are defined
in luametatex we have a bit more advanced mechanism (also relates to
compact mode) because th eengine is a bit more clever
just make sure that you don't add up features where one calcels the
other, so use for instance:
\definefontfeature[wide] [extend=2]
\definefontfeature[wideslant][extend=2,slant=.2]
\definefontfeature[widebold] [extend=2,weight=.1]
\definefontfeature[wideboldslant][extend=2,weight=.1,slant=.2]

You're missing the fact that the font has an issue. I can add a

the lines. How can i get the result of string.splitlines (s) separated into
four arguments to pass to the macro? then \foo would be

You have to provide more details about these lines. For instance, do you

There are also some commercial fonts that I got for free. Then there are fonts that I have to check because users had an issue (public ones, of different quality and useability). Of those 'trying to cover all of unicode with different fonts of the same design' I tested subsets. And of course the fonts that come with the operating system (basically all fonts that context can access during a run). We're not going to make typescripts for every combination as in practice for most documents one needs a single setup and therefore only a handful of lines of code (and likely use some typescript file for a math font). There's also the selectfont mechanism that uses heuristics to do the same. There are plenty of examples in the distribution and for a specific style that demands certain fonts one can also put the definitions in the style.

The documentation on ConTeXt is copious, and we know it: just look at the manuals on Contextgarden. But it is decidedly fragmented, and this disorientates the user. I believe, therefore, that what the community misses is a tutorial/reference manual/complete guide that comes /directly/ from the ConTeXt team (Hans, Wolfgang, etc). And, above all, that it is up to date: on Contextgarden many ‘valid’ manuals date back to many years ago, and the obsolescence of the software guides could make people say something like «well, stuff from years ago, I don't trust it». A manual in a single file that has, in short, the seal of officiality: the various resources in circulation are just as many excellent efforts by individuals, who however have put their own approach to ConTeXt into their work. Perhaps there is a more correct approach than others, more essential, which is worth knowing. I am speaking to you as a LaTeX user, and therefore I may have written a lot of nonsense in my message.

Hi all,
In writing class notes, I frequently make one-letter macros for formatted
symbols, such \v and \w for vectors. Generally speaking, one-letter names for
function/macros/variables is frowned upon in programming, but I find this
localized use very convenient.
In cont-new.mkiv, one finds definitions of \t and \w (via \let) appended to
\everymathematics, which overwrites my definition of \w every time TeX enters
math mode. I can fix this by appending my definition to \everymathematics. The
inefficiency seems minor, and I can live with it. I have a question and a
couple of points:
1. Is there a better way than adding the definition to \everymathematics?
2. I don’t think these definitions should be in ConTeXt. Let users add them if
they wish. Or add a ‘useshortcuts’ option to \setupmathematics.
3. \t and \w are undocumented, \mathword is undocumented, and it took me a
while to track down the bug it created for me. In particular, they overwrote my
definition only in math mode, and “\show\w” did not work in math mode.
Frustrating. I could add a wikipage, I suppose, but I’m not proud of the
extent of my knowledge: “\mathword{word} typesets “word” in math mode in a
normal text font, somewhat like \text{word}, and \w is an abbreviation of it
that is added to \everymathematics on startup.”
adding to \everymathematics can work fine as long as you're the last one
adding
when you overload built in commands,
\enabledirectives[overloadmode=error] % or warning
can give you some protection

limited, and loading from datasette would need hours…)
Just curious.
The smallest i have here is a https://en.wikipedia.org/wiki/RCA_1802
which actually was a very nicely designed thing (also powers the
hubble); processors never became cleaner. Now, as the kit I used only
had 512 bytes ram (later 2K or so) it really learns one how to program
efficiently (thihk of writing a simple game, save and load from cassette
player, etc in that space; dynamic adaptive functions and such) and you
know where I'm coming from'(later pascal and modula).
That said: luametatex has a smaller memory footprint than luatex
although nodes are way bigger but even that won't make it run well on an
8 bit processor, assuming it can address 32 bit mem.
Context mkii started on 4.7 Mhz intel (386) so now we're 1000 times
faster but performance gain is not linear. After all, tex has to compete
with other applications running at the same time (browsers, remote
clients, media apps, web polling apps, zoom, etc.) so it's kin dof
amazing that it actually performs okay.
What boosted performance is for instance ssd's. What might boost is ddr5
memory but that has to catch up with ddr4 first. What also boosted
luametatex is cpu cache. I remember when taco and I moved to the math
part we noticed a drop in performance, until machines got updated with
larger cache. We'd just crossed some magic threshold.
Actually, I kind of assume that we're stuck with cpu performance but
nevertheless luametatex became faster. It helps to develop on an older
machine and not on a yearly updated one as that obscures matters. (Not
that I'd not like a faster machine, but that comes at a steep price.)
Hans
ps. In the tranmsition from pdftex to luatex to luametatex one should
not underestimate Taco's effort of going from basically unreadable and
useless C output by web2c (pascal -> c) to what became the luatex C code
base (with embedded original documentation). From that we added more
functionality gradually over a decade till luametatex spun off, which
then lead to quite a bit of refactoring again (but trying to maintain
the spirit of how tex is programmed).

There are several factors that impact performance: tex engine : quite a bit faster in luametatex mp engine : quite a bit faster in luametatex lua engine : not much we can do about but inefficient macros and usage can offset any gain in engine. One thing to keep in mind is that tex is an interpreter and all gets tokenized which is more costly in a 32 bit engine than in an 8 bit one (like pdftex). And although luametatex is more efficient than luatex that gets offset by more features that come at a price, but we still win. It helps a bit to know what tex does and what macros add to that. Simple timing operations is useless as in practice we have less cache hits than with a simple loop test: tex is jumping all over memory. Bottlenecks are often noe where one expects them. Anyway, if one can choose: go for a few high perfotmance cores over dozens of so called efficient cores. (that said: luametatex runs fine on my mobile phone) Option 2: Split your book into a project with each chapter, or even part of a chapter as a separate component and compile only the chapter you are working on. Set up a nighttime (or lunchtime) run to regenerate the entire book while you're away from the computer and speed doesn't matter. Indeed. That's the natural way to deal with large documents.

starting with C99 these become unnecessary. Rather they should be like
const int luametatex_version=210; const char*
luametatex_version_string="2.10.10";
These ensure type-safety in the code and are good coding practice.
Good coding practice discussions are wasted on me (you don't want me to
look at your tex code -)
The versioning is abit special in te xdue to the fact thet some numbers
en dup in registers and others as token list (string). I have considered
changing that but it would also break some 'testing for tex version' so
for now we have to accept this mix of tex/etex/pdftex inheritance.

These potions of code which have goto should be refactored. I am a C programmer, but I know very little of TeX. If you can point me towards where should I start for TeX(perhaps TeX Book or TeX for the Impatient), I can help with refactoring of code to make is more efficient/easier. Luametatex evolves out of traditional tex so we have/keep some and although i grew up in the 'anti goto' times (pascal) there are plenty cases where i see no problem. Occasionaly I clean up such bits (when it makes sense). And I'm not going to enter coding practice discussions. Forget about refactoring ... there has already be done a lot of that and we want to stay sort of close to the original (also due to doicumentation). I know the code quite wel now and refactoring is for me counter productive. These are projects running for decades and engines need to be stable so changes come slow. You can compare the luanmetatex source to luatex and pdftex to see how we proiceed.

I was curious, so did a quick experiment: typeset \input knuth 500 times. Here
are the results:
pdflatex: 547 pages/sec
lualatex: 308 pages/sec
opentype or type 1 ?
MKIV: 130 pages/sec
LMTX: 147 pages/sec
that is weird as lmtx is always faster here (we loose some 15% on the
backend compared to luatex, maybe even more, but we gain back quite a
bit elsewhere for various reasons)
Interestingly, pdflatex, lualatex, and MkIV all generated pdf with 1112 pages,
while LMTX generated a pdf with 1250 pages. Both MkIV and LMTX take the same
time to run (8.5 sec) but LMTX generates more pages so it is faster.
puzzling
Of course, this is a meaningless experiment from a practical point of view as a
1000 page document will be more complex than just text.
% engine=pdftex 1.2
% engine=luatmetatex 1.6
% engine=luatex 1.8
% engine=xetex 2.4
\starttext
\dorecurse{500} {
\input knuth \par

125 pages, so how does your test file look

On 1/18/2024 7:56 PM, Shiv Shankar Dayal wrote: In comparison to LaTeX with LuaHBTeX, ConTeXt with LuaMetaTeX is lightning fast. pdfTeX is 8bit, and Knuth’s plain TeX is very low level – for a fairer comparison, try the TeXbook on LuaMetaTeX (I don’t know if “plain” works though). I understand that why it is slow, but the problem is that the difference is too high. My book has lots of math, so perhaps that is the reason. You can run the texbook with \tracingall and see what actually happens. The texbook uses plain tex (very lightweight) with a dedicated style (also lightweight). On the contrary context uses layers of abstraction, a more complex font, math, structure, page etc etc etc sytstem. In fact, plain tex had to be as it is because otherwise it would take ages to process teh texbook. On a pc one could see the page numbers crawl so in the end wr're quite okay nowadays. If you run context with \tracingall you'll see that more goes on. For me 40 pps sounds not that bad. If you use only text you can get to 500 pps but that's not realistic. Maybe your style is suboptimal. Also, open type fonts, opentype math, unicode, color, etc etc comes at a price. And, compared to pdftex, in most cases luametatex is faster on documents of average complexity. If you also use xml and/or metapost you migh tbe dragged down to a few pages per second while lmtx doesn't suffer much. Anyway, if you think it can be made faster you can always post code to this list that identifies bottlenecks. Of course we'll never be as fast as (pure) plain tex (no layers added) or latex (which often is advocated as faster than context).
