Re: [NTG-context] lmtx installation paths not working

[Jano Kula via ntg-context]

Hello list,

thank you all for your advices.

Aditya was right. There was some mess in PATH variable.
Lesson learned: start with explicit paths to executables.
Still where mtxrun (Windows) was pointing to the right one, which was
fooling me.

I've noticed the problem with antivirus SW during the first installation of
lmtx.
It wasn't the case this time, but one should be aware antivirus programs
don't trust mtxrun.exe.

Thank you once again,
Jano

[NTG-context] lmtx installation paths not working

[Jano Kula via ntg-context]

Hello list,

I cannot make fresh install of lmtx to work. The structure after unzipping:
C:\data\context\bin\beta
C:\data\context\bin\beta\bin
C:\data\context\bin\beta\tex
C:\data\context\bin\beta\tex\texmf
C:\data\context\bin\beta\tex\texmf-cache
C:\data\context\bin\beta\tex\texmf-context
etc.

First compilation of texfile is not working, so mtxrun --generate is the
friend.

C:\data>mtxrun --generate

These paths contain probably correct path (watch /beta):

resolvers   | resolving | variable 'SELFAUTOLOC' set to '
*C:/data/context/bin/beta/bin*'
resolvers   | resolving | variable 'SELFAUTODIR' set to '
*C:/data/context/bin/beta*'
resolvers   | resolving | variable 'SELFAUTOPARENT' set to '
*C:/data/context/bin*'
resolvers   | resolving | variable 'TEXMFCNF' set to ''
resolvers   | resolving | variable 'TEXMF' set to ''
resolvers   | resolving | variable 'TEXOS' set to 'beta'
resolvers   | resolving |

and the paths bellow have no */beta* from above, they are derived from
selfautoparent *C:/data/context/bin *(without /beta), so no surprise they
cannot be found.

resolvers   | resolving | using configuration specification

I had to switch back to mkiv. It's on Hans' agenda, but with lots of
interferencies there will be no quick fix.

Coffee break at the meeting will be the right place to ask for the higher
priority.

Images are on the remote sever and I don't want to download them with every
run. Images don't change, changed ones have different ID. Encapsualating
jpgs into pdfs might be the right conversion, because pdf inclusion is
fast, right? So I probably answered myself: write a conversion jpg -> pdf
without any changes to the image.

Re: [NTG-context] names of cached images

[Jano Kula]

Hello again,

likely a bug and one question. Using this code with lmtx:

\starttext
\externalfigure[mill][width=40mm,cache=./first,conversion=gray.pdf] %
mill...
\externalfigure[mill][width=40mm,cache=.,conversion=gray.pdf]   %
m_k_i_v_mill...
\externalfigure[mill][width=40mm,cache=./second]% no
visible caching
\stoptext

*First two figures*
Chached image in the ./cache subdirectory has a lmtx name without prefix,
the cached image in the current directory has mkiv syntax with  m_k_i_v_
prefix.

*Third figure*
The images are cached to a specified directory, only when some conversion
is used. I'd like to cache images without any transformation. Is there any
conversion which doesn't alter the figure, just caches it? Is new
conversion type needed? Or is there other way to force caching without
conversion?

Thank you,
Jano

[NTG-context] names of cached images

[Jano Kula]

Hello list,

using conversion=gray.pdf in lmtx the cached images' names have some string
in their name. I thought it's a name of random sequence of luatex cache,
but the string is the same on other machines and I don't know, where it
comes from. mkiv used to have m_k_i_v_ string there.

hacker.pdf = source image
hacker_jpg_c60ccda70ef92e32d7a6334f31c23259.gray.pdf = cached linux
hacker_jpg_c60ccda70ef92e32d7a6334f31c23259.gray.pdf = cached win

MWE
\starttext
\externalfigure[hacker]
[cache=./,
conversion=gray.pdf]
\stoptext

Is it intended behavior?

[NTG-context] very long hanging caption

[Jano Kula]

Dear list,

having images with very long captions I'd like captions to be wrapped
around the figures. I would guess hang=yes parameter could do so, but not
in my case.

 text of
|  | the caption
|  | which is
 much longer
than the height of the image
and should be wrapped around the image

The second question is how to change the distance between image and the
caption, distance parameter has no effect. MkIV, because footnotes in
columns are needed (not in lmtx, yet).

% macros=mkiv
\setupcaption[
  number=no,
  hang=yes,
  align={nothyphenated,flushleft},
  distance=4mm,
  location=righthanging]

\startbuffer[caption]
\dorecurse{60}{very long caption }
\stopbuffer

\starttext
\startplacefigure[title={\getbuffer[caption]}]
\externalfigure[cow][height=40mm,width=80mm]
\stopplacefigure

I've tried and it works as you are expecting. Unfortunately, mine are
columns inside one column page, so pagecolumns are not usable. My
workaround would be to put paragraphs into vboxes (pars are short) and I
was curious, if this workaround is needed or not.

[NTG-context] clubs and widows in columns

[Jano Kula]

Dear list,

is there a way to avoid clubs and widows in columns? I don't know, how it
would be implemented, if the task is splitting typeset vertical list.

\setuppapersize[A7]
\starttext
\startcolumns[separator=rule,
  align={right,nothyphenated}]
\dorecurse{12}{→ one two three four five\par}
\stopcolumns
\stoptext

For a different task: are there some higher level commands in ctx than
\vsplit primitive to play with vbox splitting?

Thank you,

Re: [NTG-context] nbsp in XML (S01E01)

[Jano Kula]

Hello,

the first episode was more dramatic than expected, seem to be a good series.

After the patch, nbsp is working as expected.

Useful information, thanks, wikified.

And tilde in XML is just that: the ascii tilde glyph.


Yep, but \xmlfilter can process them nicely. See some next episode.

It didn't occur to me to change it by preprocessor to the new xml elements.
You are right, one can even have more control.

Thank you all for your help,

I see your point for tilde: with finalizers in mind I was already in the
stomach, while mouth was looking at the menu. Teaser for S01E02:
finalizers.

I still would expect unicode nbsp to be expandable, otherwise I would have
to treat it somehow (no problem with that). Remember times when non
expandable/shrinkable nbsp was the first clue the book was typeset in Word?
I've checked it now and it's still the case.

[NTG-context] nbsp in XML (S01E01)

[Jano Kula]

Dear list,

first episode of series on nbsp of XML in lmtx.
Unfortunately, not that catchy as Netflix.

Used XML input has two types of non-breakable space:

   - unicode character
   - html entitity (in fact an ugly output of HTML editor)

HTML is preprocessed with ctx preprocessor (great feature!) and substituted
for unicode char nbsp or tilde.

MWE shows unichar spaces are non-breakable (see end of the first lines),
however they are not stretchable (see second line of the paragraphs).

Does unicode nbsp have fixed with in ctx?

When tilde is the replacement in preprocessor (uncomment first replacement
in preprocessor), xmlfush will display tilde (which is, as character,
non-breakable and unstretchable, no surprise).

Why tilde is displayed?

Replacing or adding nbsp (tilde) with finalizers have different results,
see next episode after this one is understood.

Thank you,
Jano

only  \enabletrackers[resolvers.details] adds the information "file not
readable", likely without any real effect.

I'm getting different results on windows and linux in more complex setup
and "file not readable" was the only difference in log files.
That's why I became interested in "file not readable" information, which
seems to be misleading.

In the end all files are are listed in
system > start used files
section and context doesn't complain it cannot open or read those files
(file not found).

The mystery of the log information remains unresolved.

These are in the distribution with same access rights as other files

Again, same windows and linux.

I have the same problem with some of my own files (some only), but have
noticed even files in the distro are "not readable". Same on windows and
linux.  Deleting cache didn't help either. What could be the reason?

This is likely the side effect of new implementation of glues in LMTX,
where you can switch the order (\hskip 3pt minus 1pt plus 2pt) and do some
other tricks. And there are more differences to *The TeXbook *as we know
it, see luametatex.pdf.

with fresh LMTX footnotes are still missing in \startcolumns as Clyde
reported:

Tried columnsets. Footnotes are overlapping text and some text at the

I was thinking goodies could be the answer even for the font fallbacks
hooks.
Unicode blocks are colored and wikified
 (simplified example) now,
which definitely helps.

I'm fine with logs and trackers, but the original idea was to search PDF by
the editor to make a visual check (made fast by searching), confirming the
glyphs are right, not only they do exist in the font. Just wanted to ask if
there is any existing machinery which could be used for that: switching
font fallback would issue, for example, a margin note command.

[NTG-context] font fallback hook (alphabet suspects)

[Jano Kula]

Hello to everybody!

Warning: 50 % of Greek glyphs in MWE, so they might be randomized :)

Is there any hook in the font fallback?

There are some Greek, Hebrew, etc. words used in the text. While
proofreading, the editor would like to check these words separately (glyphs
from different alphabets, unusual symbols, ...), so I'd like to typeset the
warning (margin note), where these words are located. To avoid usual markup
\greek{ὀρφανῖος} it could be useful to typeset a margin note whenever the
defined fallback is called.

The unfamiliar symbols could be in the main font and no fallback would be
called then (one can still define the fallback with the main font as in the
MWE, bold used for the illustration), but you might have a better ideas how
to point out these suspects.

The margin note is ment for searching PDF where one cannot search for color
(basic viewer), which could be the other approach (also visible in print).
I think, the color could be achieved with finalizers. One should also think
of hyphenation and l2r/r2l direction, so in the end the usual approach
might be the best way.

You might use other approaches, how to deal with suspects of this type.
Below the MWE for font fallbacks with distribution fonts.

Not critical, just looking for ideas.

Thank you,
Jano

when file has \continueifinputfile{} line. Below the command there is
an example. Didn't know the --global switch. It searches the file in the
distribution, but runs it in any actual folder, so one doesn't have to do a
local copy of the source file.

type-imp-punk.mkxl is a regular typescript file, which can be enabled by
\setupbodyfont[punk] in any of your documents.

[NTG-context] expansion of xml userdata

[Jano Kula]

Hello to everybody!

\setuphead[section][expansion=yes] expands xml reference to the actual
content in TUC file:

\xmlatt {xml:name::4}{title} → First section

for titles & bookmarks. The same is not true for userdata (mkiv & mkxl). Do
you know how to force expansion of userdata?

MWE attached.

Thank you,
Jano

Re: [NTG-context] Setting and measuring boxes TeX/Lua

Hello again, Hans!

Diving into functions and using context.stepwise() worked, until I've got
to: /cldf-stp.lua:48: bad argument #1 to 'resume' (thread expected) and
other errors. It was triar/error approach, not exactly knowing how
context.stepwise() works, and I was some more lua functions and iterations
before needing expansion.

Therefore I've changed the strategy (cannot give up):

   - Create named buffers with formatted content (and store measures)
   before they are needed.
   - When needed, use the reference to the buffer.

Tests looked promising. After \starttext buffers and measures are known
(both TeX & Lua). Also tested in functions, etc.
But inside the first \xmlsetup, they are not expanded anymore, they are
typeset (like \typebuffer).

   - How to have them expanded in \xmlsetup?
   - Is other mechanism better suited for storing typeset blocks than
   buffers (and will survive \xmlsetup)?
   - If none of them is possible, what are the *other **cheats *then?

Thanks,
Jano

Thank you very much!

I was trying context.stepwise several times (and \dowithnextbox,
\nextboxht and
other things). I bet there was no example of empty context.step().

The usage was: stepping in TeX end with
context.step("\\texcommands\\with\\doubleslashes") without leaving Lua.
What is the purpose of empty context.step()? Knocking on TeX's door?

[NTG-context] Setting and measuring boxes TeX/Lua

[Jano Kula]

Hello!

I would like to set framed boxes, measure their dimensions and proceed
based on the measurement. It is a combination of TeX and Lua ends.

   - Boxes are set on the TeX side. Stacking boxes (hbox, framed, vbox) in
   Lua looked too complex.
   - The content of the inner box is set on the Lua side (some
   computations).

On TeX side boxes and their dimensions are accessible, but not at Lua side,
until luacode is finished (iterations over boxes happen here). I would say
Hans already named the problem in the list: *that is always tricky as what
happens is postponing till the group ends*.

Do you have an idea how to expand the box sooner or would you use a
different approach?

Sorry for longer MWE (attached also).

Thank you,
Jano

Sorry for the delay, I had to downsample the screenshots after the original
reply didn't get through (too big) and in the end remove them completely.

Thank you for checking. Looks like a bug in Acrobat (older version
11.0.23), not ConTeXt.
What editors do you use?

After your test I was digging deeper. When I disable black plate in *Preview:
Separations* it doesn't show an overprint, the room under the letters is
white (original problem). When I remove one overprint manually in
Illustrator, Acrobat shows the remaining overprints. I've found out later,
I could use *Profile: Color Warnings*, where all overprints are visible,
but I would rather see it in separated plates.

Hope this helps someone in the future, too.

It had been awhile, so for the record.

I was looking for something similar and found out that adding a third
argument to the xml.collected reverses the iterations. Looks like the
argument has to be true in a boolean sense, so puting any "string" there
will do the trick.

for v in xml.collected(doc, "/chapter/section", "string") do
...
end

Mine latest is 2020.01.30 14:13 and I would guess it's a typo instead of
2020.10.30 (though time suggests it could be generated).

[NTG-context] caching remote images

[Jano Kula]

Hello!

I'd like to cache images (order of hundreds) from a remote location (not
all the time mapped as drive, download speed and amount of data are also
the factors).

\usepath[dirfile://./resources/**] is likely for speeding up searching not
downloading and I don't know when new images are available (when to delete
dirlist.* files), as described in workflows-mkiv.pdf.

Looks like the cache parameter in \externalfigure is used only if some
conversion is going on.

I could create a conversion which does nothing or only envelopes JPG in PDF
as .jpg.pdf (loading could be faster) and then:

if cached file exists
use cached .jpg.pdf
else
if drive is mapped
download, convert and cache .jpg
else
skip file
end
end

The source file with one  will never change or I could re-cache from
time to time to have up-to-date images cached.

Before reinventing the wheel: isn't such functionality or part of it
already available?

Thanks,
Jano

Forgot to say, I've also tried to add
\setupcolors[state=start,rgb=no,cmyk=yes]
though I think, at least state=start isn't needed anymore.
It doesn't change the overprint issue.

[NTG-context] how to set overprint

[Jano Kula]

Hello,

whatever I try, I cannot get the overprinting right (checked in Output
Preview of Acrobat). Even overprint-001.tex from the test suite
(2020-09-19) doesn't seem to have it right (latest beta). What I'm missing
here?

\setupcolors[intent=overprint]
\startTEXpage[offset=10mm]
\framed[frame=on,offset=10mm,
background=color,backgroundcolor=darkgreen]{
% \startcolorintent[overprint]
\startoverprint
text in black
\stopoverprint
% \stopcolorintent
}
\stopTEXpage

Thank you,

It is a font setup problem. Remove your font definitions and fallbacks and
change \setupbodyfont[mainface] to \setupbodyfont[dejavu] for the start (it
will cover greek and cyryllic, too).

Can you describe what you need? Are the requirements given (main font,
scripts, serif & sans, fallbacks fonts to other scripts)?

For example IBM Plex  will cover most
of what you need (except cjk for now) and there is a font definition file
type-imp-plex.mkiv in the distribution (not all fallbacks defined, yet).

Jano

just looking at the PDF (knowing nothing about bibliographies), I can't see
any italics in the text, so the first thought is: is the italics font setup
correct? I would try italics in the main text or using context default
font. You can try \enabletrackers[publications.*] and
\enabletrackers[fonts.*] to see in log what's going on. If it doesn't help
a minimal working example is needed.

First of all you don't get space even in the chapter header and as such it
passes to TOC.
Adding a space in \setuplabletext will do the trick for both chapter
headers and TOC.

\setuplabeltext

This doesn't influence the dimension of space. Well, it does, but it is a
side effect of alignment and line breaking algorithm. One cannot change the
space to a particular value/factor.

If one will finetune every space in the paragraph, this could be a way, but
it's far from a nice solution.

Which is an equivalent of \frenchspacing primitive (only regular space
after period). In most languages spacing=packed is likely the default
setting.

Not at all sure if all the above is what the purists would do, but from a

Purists wouldn't change kerning at all, because the font designer knows
best, what kerning should be used. Anyway, once the graphic designer starts
changing leterspacing (kerning), the space correction is sometimes needed,
too. ConTeXt changes the space proportionally to \setupcharacterkerning,
which is fine in most cases.

For this use case (short text in one font) primitive \spaceskip3.2pt will
do the job (ragged text thus no glue). I was searching for the more
abstract solution like \setupspacing[factor=1.05], because once in a while
the correction is needed. Or font goodies could be the way to change
spacing.

Hello,

just finished the exploration of the \xmlfunction definition based on
Massi's advice when Hans' answer arrived. This is the working code:

\startluacode
local node = "#1"
local content = xml.text(*lxml.getid(*"#1"*)*,"/color")
context.par() context("node: ") context(node)
context.par() context("lua: ")  context(content)
\stopluacode

Added a note to XML Lua <https://wiki.contextgarden.net/XML_Lua> wiki page.
I do understand the code better now, thank you.

[NTG-context] content of xml node (element) in lua

[Jano Kula]

Hello!

Processing XML I want to manipulate content of XML elements inside Lua.

I can define the Lua function xml.functions.name(t), where processing
happens, and use the command \xmlfunction{#1}{name} to pass the current
node #1 from ctx to lua as described in the xml-mkiv.pdf manual. To access
the element content xml.text(t,"/element") Lua function is used.

However, using the same function xml.text("#1",/element) directly inside
Lua doesn't work for me. Node #1 is available, but not the content of
/element.

\startluacode
local node = "#1"
local content = xml.text("#1","/color")
context.par() context("node: ") context(node)
context.par() context("lua: ")  context(content)
\stopluacode

MWE (mkiv, beta) attached.

I haven't found an example, so is it even possible? If so, which way is
more efficient?

Thanks,
Jano

One can can set register levels with keys and entries
\setregisterentry[MyIndex]
[keys:1=Sorting Key Level 1,

which stops with error:  expected near '1'

Can the colon be escaped or underlying

[NTG-context] Registration for 14th ConTeXt Meeting, September 6–12, 2020

[Jano Kula]

Dear all!

The 14th ConTeXt Meeting  is in
preparation as originally planned. All pre-registered participants are
still planning to attend the meeting. The situation is changing every day
(mainly travel restrictions), so we have decided to hold the meeting in
case the Czech Republic doesn't have red light in most of the countries in
September and the number of participants doesn't drop below the critical
number.

We will not charge a cancellation fee to attendees, if their individual
situation changes. In case the meeting is cancelled as a whole in the end,
we will ask everybody registered (except students) to donate 20 € minimum
to the ConTeXt Group  as sort of
collective insurance. The collected money will be used as the cancellation
payment to the hosting property.

Abstracts  have
been updated and registration
 is open until we
reach full capacity.

See you in Sibřina!

Re: [NTG-context] Pre-registration for 14th ConTeXt Meeting, September 6–12, 2020

[Jano Kula]

Dear list,

there are ten days left for pre-registration to ConTeXt Meeting 2020
<https://meeting.contextgarden.net/2020/>. Pre-registration counts as early
bird registration. In one week we will start to discuss the situation in
the mailing list of participants and make a final decision whether to go on
with the meeting preparations or cancel the meeting. From development in
the Czech Republic so far one can guess, there will possibly be only light
local restrictions (obligation to wear masks, serving only take-away food),
if needed.

The abstracts <https://meeting.contextgarden.net/2020/abstracts.shtml> of
some talks are already available. We have fifteen pre-registered
participants <https://meeting.contextgarden.net/2020/participants.shtml>,
just enough to make the meeting possible. People will mostly arrive by car,
some on foot or by bus/train.

We have space for ten more participants. If you have never been at the
meeting, do not hesitate to pre-register
<https://meeting.contextgarden.net/2020/register.shtml> with discounts.
Those who visited Sibřina two years ago already know what to expect (talks,
friends, food, wine, beer, music, countryside, ...). Close to the capital,
but far enough to be safe for the whole week.

Take care,
Jano

[NTG-context] Pre-registration for 14th ConTeXt Meeting, September 6–12, 2020

[Jano Kula]

Dear ConTeXt users!

The 14th ConTeXt Meeting  in the
Czech Republic is in preparation as originally planned. As nobody is able
to predict the situation in September, we have started pre-registration
only and will discuss conditions at the end of July via the mailing list of
pre-registered participants. We will take into account up-to-date travel
restrictions and health risks and make the final decision on July 31, 2020,
based also on the number of pre-registrations.

Till then no payment is wanted. All pre-registered participants qualify for
early bird discount to be paid during the first week of August.
Pre-registration doesn't bind you to pay or attend the meeting.

The ConTeXt Group board has discussed other options (on-line meeting,
postponing the meeting), but these are unlikely to happen, in case the
meeting is cancelled.

*14th ConTeXt Meeting*
*September 6–12, 2020, Sibřina, Czech Republic*

For the second time we will held the meeting at the friendly farm U Škodů,
at the eastern border of Prague. See the gallery from 2018
 by Frans Goddijn.

Topics will cover usage and development of LuaMetaTeX, ConTeXt, and
everything related. Each meeting is source of inspiration for everybody,
from beginner to expert. Friendly company is always looking for meeting new
participants, users of LuaTeX, LuaMetaTeX, ConTeXt, Metapost, etc.

There is a special discount for those, who attend the meeting for the first
time and for students. Also ConTeXt Group members are qualified for the
discount, so consider joining the group.

For more details and pre-registration visit the 14th ConTeXt Meeting
 page.

Hope to see you in September,

Re: [NTG-context] 12th ConTeXt Meeting (2018)

[Jano Kula]

Dear list,

we are finalizing the list of participants for the ConTeXt Meeting 2018
. There are few places left, if you
are interested. We cannot guarantee full service for registrations after
August 15, 2018.

You might still have doubts like one of the attendees:

"I was wondering if you could help me determine whether the ConTeXt meeting
would be of use for me.  While I have been aware of ConTeXt for some time,
I am still a relative novice.  I have used it to do some basic formatting
for letters, contracts and envelopes but I am yet to understand LuaTeX,
MetaPost and other add-ons.  I would like to learn more but I am concerned
I will not understand much of the programme.  Who is the target audience
for the meeting?  What is its main purpose?"


Here is the answer:

"The meeting is meant for everyone. Whatever experience you have, it is
always a great source of inspiration. Of course, you will not become a
master in the field in five days, but you will see how others are using
ConTeXt, what are their workflows and tools and can learn a lot. If you
show the audience, how you are using ConTeXt in 15-30 minutes (not
compulsory), you will get a feedback how to do things better. Meetings are
very informal, so no worries you wouldn't fit in. And you can always
discuss your use cases with Hans, Taco, Luigi, Alan and others. At least
they can show you how to start with different topics, which helps novices a
lot."


Rooms are ready, food & beer is ready. Even small pool is ready.
We are starting soon!

See you there,
Jano

[NTG-context] location of converted images

[Jano Kula]

Dear list,

images converted on-the-fly (m_k_i_v_*) are stored in the same folder as
original images. Is there an option to change cache folder? Original files
are stored in the read-only location.

Script convert offers --outputpath option, but I would like to make the
switch with script context, using mtxrun --script context .

Taco's talk 'mtxrun scripts' at the meeting
 will hopefully show
us even more magic.

Thank you,
Jano

Re: [NTG-context] installing latest stable version

[Jano Kula]

Hello Hans,

thank you. Knowing you are using Windows, here are Ubuntu steps:

   1. ctx beta installed as usual in dir with first-setup.sh
   2. source tex/setuptex (setting paths)
   3. cd tex/texmf-local
   4. ln -s /path/to/fonts fonts
   5. mtxrun --script fonts --reload
   6. mtxrun --script fonts --list --all

Fonts in /path/to/fonts are not listed.
The structure of the directory is:
/path/to/fonts/opentype/brousil/RePublic/RePublic Bold It Std.otf
/path/to/fonts/opentype/brousil/RePublic/RePublic Bold Std.otf
/path/to/fonts/opentype/brousil/RePublic/RePublic Regular It Std.otf
/path/to/fonts/opentype/brousil/RePublic/RePublic Regular Std.otf

It used to work this way.

Re: [NTG-context] installing latest stable version

By the way, was there any change to the font searching lately?
I used to create symlink /ctx-version/tex/texmf-local/fonts and after mtxrun
--script fonts --reload these fonts were recognized.
With beta it doesn't seem to work, I've double checked the older versions
where same symlink behaves as usual.

Hello,

installing latest stable standalone version on Ubuntu 16.04 x64:
./first-setup.sh --context=current --engine=luatex

fails with:
This is LuaTeX, Version 1.08.0 (TeX Live 2018)  (INITEX)
 system commands enabled.
error in callback:
...018/tex/texmf-context/tex/context/base/mkiv/luat-cod.lua:194: attempt to

Sure, I'll check the page numbers in the register are right, especially at
the page borders.
Could be improved, if the printer wouldn't be knocking on the door.

Re: [NTG-context] Sorting of abbreviations in index

[Jano Kula]

Hello Hraban,

have a look into the TUC file to find out, what's going on. I'm sure, Hans
would come with a more efficient approach, but this works here. Especially
the abbreviation table is probably stored on the fly somewhere, not only in
the TUC file and the table could be stored once.

Change definition to:

\def\Abk#1{\ctxlua{WriteToIndex("#1")}{\sc\lowercase{#1}}}

Add lua code to preamble:

\startluacode
function WriteToIndex (abbr)
-- test, if table exits already
if structures.synonyms.collected["abbreviation"] then
local abbreviation_entries_table =
structures.synonyms.collected["abbreviation"]["entries"]
local abbreviation = abbr
local meaning = ""
for i=1,#abbreviation_entries_table do
   local def = abbreviation_entries_table[i]["definition"]
   if def["synonym"] == abbreviation then
   meaning = def["meaning"]
   end
end
context.Sach(meaning .. " (" .. abbreviation .. ")")
end
end
\stopluacode

Abbreviation isn't used then (no \infull), so you need criterium=all to
display the list:
\setupsynonyms [abbreviation] [textstyle=normal,criterium=all]

Complete example attached.

Regards,
Jano

You can’t put a keyword (chapter) and a assignment (criterium=local) in the 
same argument
of a setup-command, what you’re looking for is 
\placelist[chapter][criterium=local].

Still, how to do the same with subsections manually inserted by

Longer Story

Predefined \startchapter|section inserts titledata in TUC file:
  [titledata]={

   [title]=Chapter,
  },
  ...
  [titledata]={
   [label]=section,
   [title]=Section,
  },
while \writetolist[subsection]{whatever}{Manual Subsection #1} inserts 
userdata:

  [userdata]={
   [first]=whatever,
   [second]=Manual Subsection \\recurselevel -1,
  },
Is this the reason and can I force to write titledata in the TUC file?

Real case is of course more complicated and also PDF hyperlinks should work.

I guess you want to say [...]  it would [not] break the overall design at all

It does make reading more difficult. I still cannot decide. In the end 
legibility should be more important, so ragged right is better like you said.


Sure, I wanted to say: it would not break the overall design at all :)


Just wondering, why is Optima-Regular embeded so many times?


We wanted to have a sans serif font for the viewgraphs that matches the Palatino (orig. 
1948). So we went for Optima (1952-1955 and also from Hermann Zapf). Wikipedia says 
Optima's capitals (like Palatino's) are directly derived from the classic Roman 
monumental capital model [...]. I think, it does look good together. We also wanted 
a TeX Gyre font as main font, so that it is available on every system.


Of course a good choice, but I meant something different. When I have a 
look at the Properties of the document in the Adobe Reader or just list 
the fonts with pdffonts command on linux, then Optima-Regular is 
listed 141 times. Figure labels use sans serif, so I'm wondering why so 
many times the font is included.

Nice work! Decent and nice design, good typesetting, I assume some hand 
work which of course cannot be avoided to make the result pleasing.


Just two remarks to the layout. Figure descriptions set in to the block 
(narrow column) produces too large spaces in the lines often. Ragged 
text would suit it better, I think.


Side notes set ragged left (rigth justyfied) on left pages are quite 
difficult to read, I would make them ragged right (left justified) on

[NTG-context] rotated columns

[Jano Kula]

Hello to everybody,

how to rotate balanced columns to avoid the prevdepth conflict? I've 
tried \rotate, \framed (to box the content), \vbox, \hbox, etc. with no 
luck.


\starttext
\startcolumns[n=2,balance=yes]
\input tufte
\stopcolumns
\stoptex

Thanks for the hints,

Jano

Re: [NTG-context] rotated columns

[Jano Kula]

Hi Wolfgang,

the example was too minimal :)

This is what I want to achieve:

\starttext
\rotate[rotation=90]{
\startframedtext
\startcolumns[n=2,balance=yes]
\input tufte
\stopcolumns
\stopframedtext
}
\stoptext

Rotation is done in \hbox. To get kind of minipage I frame it first, 
as you suggest somewhere else on the list. But then balanced columns are 
lost. Without framed text the prevdepth conflict appears. I do 
understand, the columns environment needs to know the available space to 
compute and balance columns, but playing with height parameter in 
\rotate or \startframedtext didn't help either.


This is still very simplified situation of the problem to typeset some 
material in balanced columns (which is the most natural way, not 
necessarily with this kind of columns) and then rotate the typeset 
material and put in into the margins (just the part of the whole typeset 
page).

Jano, thankyou very much.

It is a songs book, and I need an author table of content.

Your solution is very good, works fine, but using \pagenumber or

I replace \pagenumber with a incremental number to assure the label sorting.

So using the original sample, instead of:

A\index[arbol+\pagenumber]{arbol+rojo}\page
B\index[araña+\pagenumber]{araña+linda}\page
C\index[arbol+\pagenumber]{arbol+verde}\page
D\index[araña+\pagenumber]{araña+grande}\page
E\index[arbol+\pagenumber]{arbol+blanco}\page


it is now

A\index[arbol1]{arbol+rojo}\page
B\index[araña2]{araña+linda}\page
C\index[arbol3]{arbol+verde}\page
D\index[araña4]{araña+grande}\page
E\index[arbol5]{arbol+blanco}\page


Even it´not elegant, the Author index is very nice!

Maybe yo know why I can´t make it work.


Are you using MarkII or MarkIV? In mkiv the above solution works here. 
In mkii \expadned makes it work as Vianney has already suggested.

Re: [NTG-context] index sort question

[Jano Kula]

Hello Horacio,

if you have only one index item per page, than on the second level you 
can use \pagenumber for sorting:


A\index[arbol+\pagenumber]{arbol+rojo}\page
B\index[araña+\pagenumber]{araña+linda}\page
C\index[arbol+\pagenumber]{arbol+verde}\page
D\index[araña+\pagenumber]{araña+grande}\page
E\index[arbol+\pagenumber]{arbol+blanco}\page


The first level should be sorted alphabetically, because
1) you need to group index items according to first word (arbol, araña)
2) if the first item in the publication would start with z, than you 
would have Z as the first letterhead in the register (according to 
what you want), not speaking about others, so you could get Z G I E A N 
L ... as an alphabet, and nobody would find anything.

By far the easiest and most portable solution would be if you could

for the whole alphabet), but then you need to make sure that you don't
use any commands for lowercasing/uppercasing words. If you need
details, I can help you out, but first exact transliteration rules are
needed.


I was thinking, since using \lccode for hyphenation is really a wired
choice (I'm sure don has a good reason back then, but such things are
usually no longer relevant), and since it is used in a sort of
controlled environment (playing with \lccode's for hyphenation is not
ever one's toy), may be luatex can break the backward compatibility in
the hyphenation area and have a dedicated new code, \hycode or
something, only for hyphenation purposes (may be backward compatibility
can be kept by using it in addition to \lccode, maybe).

What do you think?


just any letter (catcode letter) would do and the rest is to be
controlled by the patterns


The issue here is that we want to make some character equivalent to each
other, e.g. ' and ’ which are needed for some languages, without the
need to duplicate the patterns.


Before jumping too deep to the subject, consider if it really worth an 
effort. There is not much more then, titles written in the 
transliterated text. No continuous reading.


My experience says, whatever language is the original title, reader 
usually expects hyphenation similar to the language of the main text. 
Whenever I've used English patterns in English titles (even citations), 
they where changed by the Czech proofreader -- though they were 
perfectly correct in English -- to resemble Czech patterns. I'm not 
saying it is the right approach, but from the readers' and proofreaders' 
point of view if he reads in Czech and doesn't now English patterns or 
even English, patterns different from Czech are disturbing.

Re: [NTG-context] register sorting

[Jano Kula]

Hi Steffen,

Hi,

I just installed todays beta and I am not sure if regoster sorting is working 
properly.

Eg. I modify (see below) the example from tricky-002.tex and I would like to 
achieve ...

accession
Action Plan
association

But none of the four methods (before, after, first, last) gives this result!!

What is wrong?


Methods were rewritten to give more flexibility. From the Hans' explanation:

\startquote

[pzm][mc] = [plus|zero|minus offsets][mapping|cases]

uc == unicode order

ok, a bit cryptic but one can now choose methods more explicitly (with 
the four predefined)


cases   : lowercasing with shapebased pre/post injection
mapping : given language mapping with shapebased pre/post injection

Not all combinations make sense so we might need to figure out which 
ones to document. With too much simplification (shape based) the sorter 
will not sort right as there always need to be some distinction.


\stopquote

Bellow is the example with possible combinations, so try which one suits 
you best.


At least method={zm,mc,uc} gives what you want, but I don't know your 
border cases.

Re: [NTG-context] break after index

Hi Steffen,

I am working on a book right now where the author set 4906 index marks ... 
sometimes right-in-the-middle of a word, but most often behind (and before dot 
or comma).


and what about to clean up the file with regular expression similar to this:

sed -e 's/\b\(\w*\)\\index{\([^}]*\)}/\\index{\2}\1/g' old.tex  new.tex

I would guess, that index entries in the middle of the world break 
kerning and hyphenation.

Re: [NTG-context] entries in registerentry

[Jano Kula]

Hi Steffen,

On 10/13/2010 07:23 PM, Steffen Wolfrum wrote:

Hi,

I don't understand the concept of entries in registerentry :o(

Say, you have this example:

\starttext
\placeregister[index]
\page
page 1
\setregisterentry[index]
  [entries:1={eins},
   entries:2={zwei},
   entries:3={drei},
   label=range]
\page
  page 2
  text
\page
  page 3
\finishregisterentry[index][label=range]
text
\stoptext


\setregisterentry writes only one index entry and entries:1, entries:2, 
entries:3 are the levels of this entry, so \setregisterentry in your 
example is equivalent to


\index{eins+zwei+drei}

and you get

eins
  zwei
drei number


Why does only have entries:3 the index range 2-4, both entries:1 and 2 are 
emtpy?
What should I write in order to have all of those entries referering to the same 
2-4?


Hans might have a better hint, I would write these entries three times.

Jano
