Hi,
I want to typeset a table where some of the column headings are really long,
while in the columns itself consists only of numbers.
Therefore, my idea was to rotate the column headings but not 90 degrees (I
found some solutions for that) but 45 degree.
It then would be beneficial to push together the rotated cells, so the text of
one cell actually starts above the previous cell.
Do you know, how to achieve that?
Here is a minimal example:
```
\startsetups[table:rotated]
\setupTABLE[frame=off]
\setupTABLE[row][first][bottomframe=on, style=bf, align={center, low}]
\setupTABLE[row][2][align=flushright]
\stopsetups
\starttext
\define\tablerotate{\dontleavehmode\rotate[rotation=-45, location=high]}
\bTABLE[setups=table:rotated]
\bTR \bTD \eTD \bTD \tablerotate{Water buffalo} \eTD \bTD
\tablerotate{Mexican redknee tarantula} \eTD \bTD \tablerotate{European turtle
dove} \eTD \eTR
\bTR \bTD Amount of legs \eTD \bTD \digits{4} \eTD \bTD \digits{8} \eTD
\bTD \digits{2} \eTD \eTR
\eTABLE
\stoptext
```
I would like to achieve that the text "Mexican redknee tarantula" is typeset right and
above of "Water buffalo" so that the single columns have a width that is similar to the
width of the single digit coming in the second row.
To visualize this, I patched the PDF of the above example to the desired
result. See the attachment.
You can use Metapost.
Thanks for this solution. It, however, seems to fail with any other angle than
315° (I tested 305, 325 and 314).
Try
xyscaled(\the\struttotal,abs(sind(\MPvar{rotation}))*\the\widthofstring{\MPvar{text}});
with sind instead of sin. And maybe with abs around it, but one can
think of improvements for smaller angles. It all depends on what one
wants.
here is an alternative
\bTABLE[frame=off]
\bTR[align={middle,low}]
\bTH \eTH
\bTH
\dontleavehmode\kern1.5em\llap{\rotate[rotation=315,frame=on]{\strut

\bTH
\dontleavehmode\kern1.5em\llap{\rotate[rotation=315,frame=on]{\strut

\dontleavehmode\kern1.5em\llap{\rotate[rotation=315,frame=on]{\strut

\eTR
\bTR[frame=on,align=middle]

\bTD[width=3em] 4 \eTD
\bTD[width=3em] 8 \eTD
\bTD[width=3em] 2 \eTD

Oh, I'm afraid that my “I hope for the future.” has now led to a
misunderstanding.
I would like to archive my documents as pdf/A-2a. As a reference to the
German Bundesarchiv, which recommends pdf/A-2a in the first instance -
and pdf/A-2u in the second.
I simply noticed that, as described in my initial email, the pdf/A-1a
and pdf/A-2a variants do not pass the validation test with verapdf.
Since there seems to be no way around this, I will probably have to fall
back on the second recommendation.
You cna try this:
\setupinteraction
[title=TITLE,
subtitle=SUBTITLE,
author=AUTHOR,
keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}]
\setupbackend
[format={pdf/a-2a},
profile={default_cmyk.icc,default_rgb.icc,default_gray.icc}]
\setuptagging
[state=start]
\enabledirectives
[backend.usetags=mkiv]
\starttext
\chapter[chap:testing]{Testing}
\input knuth
\input tufte
\stoptext
This validates in the verapdf that i have installed (1.25.271).
So, you choose some standard (which we try to accomodate as good as
possible but who knows ... this one is a bloated one due to the icc
profiles). As you want tags we enable that (no need for it as long as
one is not finished with the document unless one wants to trace). We
also load the the old school mkiv mapping.
You can define your own mappings if needed. After looking into the
latest greatest volatile specifications Mikael and I decided that we
don't want to be waste too much time on it (at least not now as we hav
emore interestign thinsg to work on) and settled for what validates and
let users themselves decide. We mostly aim(ed) at making the university
enforced tools happy.
Structure in pdf is (to put it mildly) a mess, insufficient and never
will be (conceptually) okay, which is probably why it keeps being
adapted to what some applications can support or not. We don't want to
cripple what structure in ConTeXt we have. For the long time
accessibility tagging (there are other kinds of tagging being in use)
has been around for a quite vwhile now it has been the domain of acrobat
professional toolkit so in a broader context it is kind of useless anyeay.
(One can wonder what organizations demanding it really have in mind,
given that older stuff doesn't validate and probably no one ever checked
how useful it is. But that's often the case with standrads like this:
some checkbox ticks so we're okay.)
So, the best we can do is to provide some flexibility, as usual in tex
tools,
Hans

Hello Hans,
thank you for your answer for now.
\setupbackend[format=pdf/ua-2] should work but validation test via
verapdf failed.
I hope for the future.
Because we don't want a bloated pdf by default, if you want tagging then
you also need to set:
\setuptagging[state=start]
and you can try with
\setupbackend[format={pdf/ua-2}]

Be more specific. Mojca I have two specific interests. I want to make asymptote work with ConTeXt but I can live with including generated images and use PDFs. There is zero change that that will be integrated as it introduces a (long term) dependency. It's pretty much geared at latex anyway and we would need some backend that fits in. We already have metapost (and will extend that over time). It is however possible to load libraries at runtime as we can do with some optional libraries (these linbraries themselves are not included either but loaded on demand). One can add extra ones locally in which case we don't have to worry about the style of their interface. Of course that also means maintaining them as one needs to keep an eye on (changing) api's. Keep in mind that if you do that you need to maintain it for decades to come. We also have a foreign interface (no ffi but kind of) but afaik no one ever showed interest in that. With respect to external pdf files ... there are several ways to optimize that and only process files when they change as we do with other inclusions. The second interest is in Aditya Mahajan's syntax highlighting module. It is very nice but it invokes VI making the entire thing slow. I understand the advantage of using VI is that we do not have to implement anything when a new language comes. VI will have syntax highlighting and it will be automatically done for us. Again, when one caches these snippets there is little overhead involved. One could look into some socket communication but language servers tend to be huge and evolving. But of course one can play with that in a local variant, after all the engine code is included in the context distribution. Syntax highlighting is kind of personal anyway, we have soem 'reference'highlighting (which reflects how contetx is codes) but that is also personal. No solution suits all.

Hi,
Not sure what you mean by a core ConTeXt developer. I think, as with anything,
you get better at it by using it extensively. I would focus on a use case of
interest and take advantage of ConTeXt’s unmatched extensibility to automate
much of it as possible. Then you ask for help when you get stuck.
If you want to contribute to ConTeXt, maybe start by having a look at the
source and try to understand what’s going on (should be accessible to you since
you are a C developer). If you identify a bug, or want to propose a feature, I
am sure the community will support you however it can.

I want to contribute to ConTeXt. I think that the steps for me should be:
Just curious: is there something that you miss.
1. Learn TeX
2. Learn LuaMetaTeX
Makes sense.
and then I can approach the C code. It won't make any sense if I just
start reading the LuaMetaTeX code.
Development of LuaMetaTeX (the engine) is mostly finished. We now
entered the stage where we conduct experiment with the more difficult
aspects (often unsolvable due to constraints). For that one needs to be
quite a bit experienced in tex and the way context approaches things.
As an example, project like updating math took many man-years and
intense testing, discussion and experimenting (so also quite some long
term commitment). In a similar fashion (and related) we now are playing
with the par and pagebuilder where user input and testing is required.
Things like that get discussed at meetings and personal cummunication.
The source code is under rather stict dev regime. We don't want to break
compatibility, all has to fit into the user interface, performance might
not be impacted significantly. We don't have an official dev team but
everone knows what the de-facto team is (last week those that had time
and were within reasonable traveling distance met at the context
meeting) and it's also a kind of friends and fun thing where everyone
brings in competence and inspiration. At such meetings we also set the
objectives for the next year.
That said, the usual way to come up with something that a user needs is
to use a mix of lua, tex and metapost and wrap that in a module. That
way the core is not crippled. Also, no all has to go into the engine but
is done in Lua.

Can you explain what you mean with less compact?
The default baseline distance of LaTeX is AFAIK 1.2 times the font size,
adding
\setupinterlinespace [line=1.2\bodyfontsize]
to the document setup should produce similar results with ConTeXt.
that interlinespace is kind of bad as it can lead to inconsistent line
spacing
[dp \the\strutdp] \dorecurse{"}{%
\ifdim\fontchardp\font#1>\strutdp
\char#1 \space
\fi
}
[ht \the\strutht] \dorecurse{"}{%
\ifdim\fontcharht\font#1>\strutht

So, if oen really wants to go that cramped, maybe try
\setupinterlinespace [line=1.2\bodyfontsize,height=.75,depth=.25]

Example: आनन्द
This seems to be out of date and for most academics (especially outside

IAST to Devanagari (?)
What we need are thus three elements: switching the language to Sanskrit
temporarily (the main

AsishilaSan),
and enabling input of sanskrit in transcription (input: ānanda -> output
आनन्द).
Just a background note: Transcription and Nāgarī are not as equivalent
as one would want. In
transcription some word divisions are indicated that are not indicated

makes reading transcription easier — for those used to it. For most
Indian scholars transcription

alphabets.
If someone could tell me how to get all these things into a few

grateful. My own attempts, mostly trial and error, did not succeed.
You can take a look at
type-imp-indic.mkxl
which has some about transliterations (there is a subsystem for that)

Hi,
Something seems wrong with the align processing inside \setupmargindata,
because using a macro like
\def\Inmargin#1{\inmargin{\blank[-line]\startalignment[inner,nothyphenated]#1\stopalignment}}
works ok (the \blank[-line] is a side-effect of using the environment inside a

can you test with

By meaning it is a minimum working example, it demonstrates the problem,

placed in registers, some information loaded from an entire passage
sometimes \include passage.tex (though not displayed, cuz it contains
indexes, registers, etc.), and its always leaving this gap after the
section title. I've used \starteffect[hidden] as one attempt to hide it,
but it only makes it basically invisible, but still present. How to make
it invisible and take up no space? Or can I hide all that information
inside some part of the section title?
\startchapter[title=foo]
\index{xxx}
whatever
in this case there is no gap, and usign some 'effect' then actually can
be the reason for messing up spacing (as it goes into horizontal mode)
in the case of an index, just keep the command and don't place the
register, no need to use effect as \index is not visible there anyway)
in the case of a footnote, just use the trick i mentioned and put the
footnote in the title, not on a line of its own

So I can recognize latex (with 99% accuracy when no commands similar to context are used) but then I'd need to buy and read a couple of few thousand page companions to get a moderate complex document done. I'm sure that doesn't surprise Willi. Last context (and bacrhotex) meeting Harald played this 'can you recognize this language' game with the audience. One has to be real old (or curious and collecting languages) to be among the winners. It's all about 'need to use something' and the definition of 'knowing'. I can recognize a tree but name a few.

A lot of stuff.
The author is quite opinionated against ConTeXt/LuaTeX, knows only the
HarfBuzz version and can’t appreciate an independent, complete OpenType
renderer, it seems.
Different worlds, different audiences, different objectives so a waste
of energy to discuss i guess.
I can only say that when we started with luatex there was nothing that
fit the requirements (oriental tex sub project) so we decided to go the
lua route and could always be amopng the first to support new stuff
(color fonts, variable fonts, adaptations, etc). And I'm not even taling
math in luametatex here.
But as said: we serve a different audience, not the applications and of
course the tex community doesn't have the big-tech funding and resources
so ... and we try to keep a low profile anyway.

Greetings,
I have been trying to make font feature sets that allow me to write

about. MWE:

With STIX Two, c2sc (and smcp) works with any language as long as one
doesn't select a script in the font features, else it only works with
the chosen script. With New Computer Modern, it just doesn't work with
any latin text no matter the script chosen. That is, plain small caps
work, caps to small caps don't. What could be the reason to it? Is there
anything I could do to mitigate it?
you can try
\definefontfeature [capstosc] [c2sc=always]

I wonder if your test environment is really equivalent to a fresh

are allowing it to appear to succeed. Does it work if you try inside
Docker?
I'm not sure what else I can try. Where's that `luatex` call supposed

Does it work without --luatex, i.e. does it work for LMTX but not MkIV?

Very nice, thank you!
I see some similarities to the "visible on" technique [1], I posted in a
previous thread.
You mean the horrible transparency hack there?
What comes there really handy are range specifiers, what seems not possible
with this interface.
For example: "visible on=<2->" renders the content on every page except the
first one
or "visible on=<1-5,13-15>" on the first page up to the fifth page and from
page 13 to 15.
The mechanism stems from the Beamer overlay specifications, see section 9.3 of
the manual [2]
and can be much more complicated with modes (section 9.6.2).
I don't know beamer other than seeing presentations at meetings but I
assume that it has some accumulator. We do have steppers in mkii / mkiv
already in the presentation styles. The conceptual cleanest of them
depends on the viewer and free ones never catched up so that one is
acrobat specific. The stacker discussed now is just similar to the
metapost one but then at the tex end. (A quick hack with room for more a
bit more effiency if ther ei sneed for it.)
To add this to the new interface, if you want that, the stack layers above need
some kind of order,
which is implicit for numbers:
```
\definestacking{one}
\definestacking{two}
\definestacking{three}
\definestackingorder{one,two, three}
...
\setupstacking[criterium={one-three}]
```
The order could also be implicitly defined after the order of the
\definestacking calls.
Or would it be possible to have numbers always automatically (additionally)
available as stacking layer?
So that this "just" works:
```
\startbuffer
This is a test \stacking [1] {and a proof} of \stacking [2] {concept} indeed.
\stopbuffer
...
\setupstacking[criterium={1-}]
```
I also wondered, if it is possible to define a lot of layers semiautomatically
in Lua
(in some graphics I needed around 20 layers). It seems that numbers in layer
names currently are not allowed.
Is code like this possible somehow?
```
\startluacode
for i = 1, 20 do
context.definestacking(string.format("l\letterpercent.d", i))
end
\stopluacode
```
The next version already will have this:
%D For Aditya Mahajan: ranges and such.
%D
%D \starttyping
%D \starttext
%D \startstackingsteps[1,{1:2,201},{1:3,301},{1,2,4},{1-5},{1-6},{1-7}]
%D \startTEXpage
%D \startstacking[1] \framed{ONE}\stopstacking
%D \startstacking[2] \framed{TWO}\stopstacking
%D \startstacking[201] \framed{MORE} \stopstacking
%D \startstacking[3] \framed{THREE} \stopstacking
%D \startstacking[301] \framed{INDEED} \stopstacking
%D \startstacking[4] \framed{FOUR} \stopstacking
%D \startstacking[5] \framed{\im {\sqrt {
%D \stacking[6] { 1 + x ^ {
%D \stacking[7] { 2 } } } } }}
%D \stopstacking
%D \stopTEXpage
%D \stopstackingsteps
%D \stoptext
%D \stoptyping
The range interface is not different from the one we use in other places
so it was a braindead patch. Numeric stacking id's don't need to be
allocated. The example shows that it is rather general applicable
although there are some border cases (that if needed we can intercept
but I assume sane usage).
No upload yet unless there is a hurry.

i installed an alpine on WSL to see what happens
- it looks like some 32/64 bit mixup ... this is a side effect of the
fact that it take a bit of effort to see if we need musl
- the buildbot doesn't generate the binaries (i can't login to the
machine to check if the client is running at all)
i'll see what i can do (will give some upload noise on the list)
btw, i can compile luametatex on WSL alpine so i can use that binary
you can do that as exercise:
- apk add build-base
- apk add cmake
- go to tex/texmf-context/source/luametatex
- chmod 755 build.sh
- ./build.sh
- copy bin from build/native

At least, I would like to be sure what is going on here.
Hovering over links is basic precaution before clicking them.
To explain that to others, I’d rather know how Acrobat (Reader) behaves
in these cases.

3: https://contextgarden.net
Many thanks for your help, Hraban.
Thanks to your confirmation, I investigated the issue further (since
there had to be something different with my documents).
\setuptagging[state=start] is the culprit. "link" is the word displayed
when links are hovered over.
It's not that hard to get something less generic displayed but the
question is what and in what detail. A lot of this stuff is not
consistent over viewers and it being part of the user interface might
also change over time (some viewers also interpret the page stream for
urls).
Anyway, a next upload will have this:
% \disabledirectives[backends.references.descriptions] % just link
% \enabledirectives [backends.references.descriptions] % some
detail (some todo) (default)
% \enabledirectives [backends.references.descriptions=reference] % a bit
less
so that you can experiment a bit with it. We might at some point provide
optional descriptions per link but the quesiton is how to cleanly
interface this (easier if you use \define... instead of your own macros
for urls).

Probably only Hans (or Wolfgang) can give a complete answer here. But
\startsetups [*default]

An interesting new feature is the possibility to set penalties depending
on left and right page, by using options. For example
\startsetups [*default]
\directsetup{*reset}
\frozen\clubpenalties 3 options 4 1500 3000 250 500 0 0 \relax
\stopsetups
sets club club penalties 1500 for first line and 250 for second for
going from left page to right page (and then 0 for the rest) and 3000
for first line and 500 for second (and rest 0) for going from right page
to left page.
I hope this helps a bit.

If you use that kind of simple graphics, you can avoid this transparency
hacking by using metafun:
\setupbodyfont[dejavu]
\starttext
\startuseMPgraphic{test}
pickup pencircle scaled 2mm ;
draw fullcircle scaled 3cm withcolor darkred withstacking 1 ;
draw fullcircle scaled 2cm withcolor darkblue withstacking 2 ;
draw textext("one") withcolor darkgreen withstacking 11 ;
draw textext("two") withcolor darkgreen withstacking 12 ;
draw textext("three") withcolor darkgreen withstacking 13 ;
\stopuseMPgraphic
\startTEXpage[offset=.25ts]
\useMPgraphic{test}{stacking={1,11}}
\stopTEXpage
\startTEXpage[offset=.25ts]
\useMPgraphic{test}{stacking={2,12}}
\stopTEXpage
\startTEXpage[offset=.25ts]
\useMPgraphic{test}{stacking={1,2,13}}
\stopTEXpage
\stoptext
It's an already old feature but probably not that well known. If needed
I can make something similar at the tex end.

Not at all. Sorry for my poor wording. From the PDF-1.7 spec itself (https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf#search=ByteRange): This range should be the entire file, including the signature dictionary but excluding the signature value itself (the Contents entry). Other ranges may be used but since they do not check for all changes to the document, their use is not recommended. When a byte range digest is present, all values in the signature dictionary shall be direct objects. Signatures in PDF-2.0 loose their possibility of other ranges than the entire file. Their use is simply not allowed. so more limited then to basically two ranges Sorry for insisting, but please don’t require plaintext password in the command line (again, OpenSSL prompts for it). not if we use the library Weird, on both Linux64 and Win64, the openssl runner requires the openssl binary to be installed. i meant the --library option Many thanks for your help, Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

Dear list,
the latest version of LMTX can digitally sign PDF documents. It requires
OpenSSL installed (since it does the crypto part).
I have two issues that I would like to be tested by others.
A sample certificate may be found at
https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/message/ECSXLVMT3TMQBIHA2UZJPWJN7OVV5334/attachment/2/mycert.pfx

Here is a sample document (actually provided by Hans):
\setupinteraction[state=start]
\definefield[signature][signed]
\defineoverlay[signature][my signature]
\starttext
\startTEXpage[offset=1ts,frame=on,framecolor=darkblue]
sign: \inframed[background=signature,framecolor=darkred]
{\fieldbody[signature][width=3cm,option=hidden]}
\stopTEXpage
\stoptext
After compiling the sample, you need to run:
mtxrun --script pdf --sign --certificate=c.pfx --password=ABCabc doc.pdf
i use a pem
Password will be prompted again ("ABCabc"), since it is an encrypted
certificate (also for the public part).
Could anyone confirm the following issues?
1. The signature I get is wrong, unless I apply this patch
(https://mailman.ntg.nl/archives/list/dev-cont...@ntg.nl/message/T3OCKVZWTUTIXCSOKIFRVJ4X76MROZHE/attachment/3/byterange.diff
[sent by myself to the devel list]).
2. I cannot get any signature display in Acrobat. Does any PDF viewer (I
have tested this with pdfsig from poppler and MuPDF-GL) display the
digital signature at all?
this whole digitial signing is a bit of a scam imo ...
- one has to buy a specific kind of certificate
- often one is supposed to use some token
- when the root cert expires one has to resign
- reader has root certs built in and checking is supposed to be online
- it doesn't come cheap and supporting / testing is not something one
can expect for free (so i can't really test it)
... so just some business model and not really something one can do out
of the box
... apart from ...
- just sign with some certificate and don't expect viewers to do something
- offer a service to upload the document for checking when a user is in
doubt
- that can be done without root cert and basically works as long as the
service works
concerning the suggested patches: this <whatever> boundary is a
bit fuzzy and i found that different viewers / checkers expect either or
not +/- 1 but i didn't check recently if things have improved
if we know the specs and have way to test ... no big deal to fix a few

Hi,
I'm using LaTeX-Beamer and TikZ for figure typesetting.
With this combination, it is easy to combine Beamer's animation system with

This way, the resulting PDFs contain the full graphic on every page, but parts
of it are invisible for a specific page.
One of these files is attached as an example.
The problem is to embed these PDFs into a ConTeXt document.
For example, this MWE seems to not respect transparency (see mwe.pdf):
```
\starttext
\externalfigure[fig.pdf][page=1]
\stoptext
```
I use Okular/Poppler as PDF viewer.
Can I fix this somehow or is it a bug somewhere deeper?
next time check the file that you include ... it has no transparency (it
has zero values)
the attached works ok

Is there a similar documentation for ConTeXt somewhere?

Just as an info. I'm using Noto symbols now:
```
\definefont[symbolFont][name:notosanssymbols2regular*default at 11pt]
\define{\yes}{{\symbolFont\utfchar{0x1f5f8}}}
\define{\no}{{\symbolFont\utfchar{0x1f5f4}}}

\yes and \no.

fwiw: 1F5F8 looks pretty bad (in otf) (i checked as i though it was a
bug in lmtx)

Hi,
thank you all for your replies so far. I guess I’ll have to live with that for
now (of course this isn’t really a problem, but a bit unpleasant to look at
when you’re used to the straight lines in LaTeX). Just wanted to add that I can
see this artifacts quite clearly on a 13 inch 1080p screen in the PDF viewer
(depends on zoom level, on some zoom levels I see nothing) and not only when
enlarging a screenshot. After all, it’s visible in my attached screenshots even
if displayed in their original resolution. (Naming of my screenshots wasn’t
very clear, zoomed.png is zoomed-in in the pdf viewer, not a zoomed-in
screenshot.)
The "left radical + rule" isn't perfect either, because it depends on
overlap. Depending on the font you can see issues at the connection
(actually these might be obscured by aliasing at low res). You can try
that outside lmtx with different fonts.
Also, because rules are often rendered differently from glyphs (and
rules can use either a line or rectangle fill) it's always been an issue
(which is also why engines have some heuristics for choosing one or the
other method).
And, as mentioned, vertical extenders also use the same etechnology as
we now use for radicals, it's just that there was never a concept like
that in engines for radicals. Arrows sit in the same category and also
use the same glyphs so there one can observe the same. Actually, even in
traditional tex arrows are made from minusus and an arrowhead
overlapping piecewise.
Maybe viewers will catch up.

So it's a linux rendering issue when taking dumps.
Not only. It also happens with all(?) PDF viewers on MacOS – at least
10.14 and 10.15, can anyone confirm with current versions?
So it’s dependend on the screen rendering, anti aliasing settings (that
you usually can’t influence).
hm, so i have to stick to windows for viewing (and an ancient hardware
laptop in order to avoid copilot and recall) but i'll check ubuntu anyway
It doesn’t affect printing – or does it for anyone? I can imagine
printing from Firefox, i.e. pdf.js, is affected, since it prints only in
screen resolution.
it's not related to math then, as there are also ligatures built this
way, although often they often are less sensitive to thsi due to
generous overlaps (unless they use a sequence of connecting strokes in
the same direction)
also keep in mind that looking at a blown up character is not that
realistic (for instance a traditional bitmap font might look great at
600 or 1200 dpi at intended size so zooming in showing raggedness is not
the normal way to see it)
btw, if one wants to observe inaccuracy, just zoom in in graphics made
by drawing programs (even of famous companies)

Using rules (traditional approach) is pretty bad in screen dumps and even regular rendering, depending on zoom; there one has interaction between the font rendering and other graphic elements (rules). Btw, vertical extensibles are not different (take the bracket which has similar constructs). Interesting is that it is straight blob connections that can show these occasional gray pixels and it only seems to happen with a little overlap. Kind of a bug we think. Hans ps. One reason when I always use (x)ubuntu when i have to use a linux desktop is that it always was set up right wrt rendering fonts and anti aliasing.

I need it as a dimension, since I do calculations with other dimensions

There doesn't appear to be any official interfaces to get the value of a

\definemeasure[mymeasure][10pt]
\newdimen\mydimen \mydimen=10pt
\definemeasure[measureexpr][1in + 27.73pt]
\startluacode

-- namespace = interfaces.getnamespace(namespace)
namespace = tokens.getters.macro("??" .. namespace)
return tokens.getters.macro(namespace .. variable)
end
-- Gets the value of a measure and converts it to an integer in sp

local function get_measure(name)

end
-- Gets the \dimexpr-evaluated value of a measure, in sp units.
local function get_measure_expr(name)
local namespace = tokens.getters.macro("??measure")
-- Undocumented, but seems to work as expected.
return tex.getdimensionvalue(namespace .. name)

-- Print the values of the lengths.
print(("="):rep(80))
print("mymeasure:" , get_measure("mymeasure") )
print("mydimen:", tex.dimen["mydimen"] )
print("measureexpr:", get_measure_expr("measureexpr"))
print(("="):rep(80))
\stopluacode
\startTEXpage
\measure{mymeasure}
\the\mydimen
\measure{measureexpr}
\stopTEXpage
Thanks,
-- Max
Indeed we can have:
local namespace = tokens.getters.macro("??measure")
function tex.getmeasure(name,asdimen)
local value = tex.getdimensionvalue(namespace..name)
if asdimen then
return value .. "sp"
else
return value
end
and when you want to avoid the namespace you can do:
function tex.getmeasure(name,asdimen)
local value =
token.getexpansion("\\tointeger\\measured{"..name.."}")
if asdimen then
return value .. "sp"
else
return tonumber(value)
end
end
which is some 4 times slower. It'sindeed not documented (although there
are some examples in accessors-001.tex) but it's in one of my todo's
because I can use it in some places (there ar emopre such todo's) after
which it will be discussed in one of the lowlelvel manuals
i'll add tex.getmeasure to the core (but a bit different)

First of all, lpaths are XPath implemented with Lua in ConTeXt. XPath seems to have as it primary purpose to address the nodes of XML trees. About your sources, the real issue here is to define whether you want TEI or TeX to be the format containing them. I mean, if you add explaining footnotes to your TeX file(s), XML won’t be source anymore. If you don’t want this to happen, you have to encode them in the TEI XML sources. One last suggestion about proofreading. This is something I learnt from personal experience. The first reading is much better to catch errors in the text than the subsequent ones. Having the text properly formatted and printed on paper helps a lot to spot errors. Reading source code is cheaper (no doubt), but the results will be poorer too. Just in case it might help, fwiw, context supports 'synctex' to xml files / nodes so that might help a bit Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___
