Re: [NTG-context] Framed & before/after

Hello,

does \framed recognize before and after keys, as mentioned here:

http://wiki.contextgarden.net/Command/defineframed
or:http://wiki.contextgarden.net/Command/setupframedtexts ?

In the following example it seems both keys are ignored:


\defineframed[AddressBox][before=\red,after=\small]

\starttext
  \green A
  \AddressBox{\cldcontext{"Hele"}}
  B
\stoptext

The values of the before and after keys are only used when you write

\startAdressBox
…
\stopAdressBox

Many thanks for your reply, Hans.

I’m afraid I wouldn’t have figured out myself in thousand years.

Subject: [NTG-context] Custom sorting of "pseudo-language" in a register
To: mailing list for ConTeXt users 


Hello all,

I’m just getting acquainted with ConTeXt, and I am finding it so much
more suitable for my work and needs. Thanks for the great software.
Here’s my situation. I write in Slovene and in English, and I need to
make numerous references to biblical passages. I want to create an
index of these citations, but I want them in the order they appear in
the Bible rather than alphabetical order. Henri Menke provided a
perfectly workable solution on TeX StackExchange[^1], but because this
is a multi-year project, I wanted to find a bit more permanent
solution. I discovered I can use Lua LPEG to parse and normalize my
citations so they are referenced in a uniform style.

My problem comes in the register sorting. Hans, I saw where in the
paste you have recommended a “pseudo-language” to implement a custom
sort in such a situation. I have almost figured out how to accomplish
this. (See the MWE below.) I have no problem with single word sections
(Genesis, Exodus, etc.). I can turn off indicators, do the custom sort
(see below), and I get the intended result. If I have a multiple word
title (Evangelij po Janezu), that technique doesn’t work. The
replacement for more than one word (or if a number is involved, like
1John) doesn’t seem to work. I have no doubt there is a good reason;
I’m just a newbie!

It seems my options are to:

1. Figure out how to do a replacement for a phrase or a book with a
number in its name. Then this technique seems to work ok.
2. Or to add an entries and figure out some way to not print the first
level in the index. So the indicator will be the book name, and
underneath the chapter and verses will be listed with out the book
name being repeated.


Are there any ideas to point me in the right direction?


You're bitten by the cleaner that kind of normalizes entries as you can 
see when you say


\enabletrackers[*sort*]

replacing spaces by \0 can help but that sort of assumes that you know 
what happens inside


So, i added some code to handle that. I also added a helper so that you 
can do:


\startluacode
local list = {
-- old testament
"Genesis", "Exodus", "Leviticus", "Numbers", "Deuteronomy", 
"Joshua",

"Judges", "Ruth", "1 Samuel", "2 Samuel", "1 Kings", "2 Kings",
"1 Chronicles", "2 Chronicles", "Ezra", "Nehemiah", "Esther", 
"Job", "Psalms",

"Proverbs", "Ecclesiastes", "Canticles", "Isaiah", "Jeremiah",
"Lamentations", "Ezekiel", "Daniel", "Hosea", "Joel", "Amos", 
"Obadiah",
"Jonah", "Micah", "Nahum", "Habakkuk", "Zephaniah", "Haggai", 
"Zechariah",

"Malachi",
-- new testament
"Matthew", "Mark", "Luke", "John", "Acts", "Romans", "1 
Corinthians",
"2 Corinthians", "Galatians", "Ephesians", "Philippians", 
"Colossians",
"1 Thessalonians", "2 Thessalonians", "1 Timothy", "2 Timothy", 
"Titus",
"Philemon", "Hebrews", "James", "1 Peter", "2 Peter", "1 John", 
"2 John",

"3 John", "Jude", "Revelation",
}

sorters.definitions['bbt'] = {
replacements = sorters.replacementlist(list),
}
\stopluacode

\defineregister
  [booksort]
  [language=bbt,
   n=1,
   indicator=no]

\starttext

One   \booksort{Genesis+5.2}
Two   \booksort{Exodus+2}
Three \booksort{Genesis+45}
Four  \booksort{Philemon+2}
Five  \booksort{John+45}
Six   \booksort{1 John 1+45}
Seven \booksort{2 John 2+45}

\blank[3*line]

\placeregister[booksort][language=bbt]

\stoptext

It probably makes sense to make this into a module but then we need to 
collect a few lists.


I'll upload a beta.

Hans


Thanks so much for your help,

Hello list,

One more question. Since I could not figure the problem with the wiki
article for a title, I have turned my attention to modify the t-title
module for my needs. If I want to add let's say a publication
location, how would I go about that?

I have copied and renamed t-title.mkvi to p-mymodule.mkvi. I have
changed the formatting to suit my needs, but I can't not figure out
how to add parameters. What is the connection to the t-title.xml
interface file?

I don't need it done for me, but I do need just a bit of help getting
going in the right direction. :-D

Thanks so much for the help and the great software!


something

\setuptitle[foo=bar]

\roottitleparameter{foo}

Dear list,

I have the following sample:

   \startbuffer[demo]
   
 
   
 a
   
 
 
   
 b
   
 
   
   \stopbuffer

   \startxmlsetups xml:initialize
  \xmlsetsetup{#1}{doc}{xml:*}
  \xmlsetsetup{\xmldocument}
 {pre[contains(@class,'typeset')]/code}
 {xml:pre:code}
   \stopxmlsetups

   \xmlregistersetup{xml:initialize}

   \startxmlsetups xml:doc
  \xmlflush{#1}
   \stopxmlsetups

   \startxmlsetups xml:pre:code
 \xmlinfo{#1}
 \xmlpath{#1}
 \xmldoifelse{#1}{../pre[contains(@class,'fullwidth')]}
 %~ \xmldoifelse{#1}{{pre[class*="fullwidth"]}}
   {\startpar Full–width.\stoppar}
   {\startpar Another width.\stoppar}
   \stopxmlsetups

   \starttext
  \xmlprocessbuffer{main}{demo}{}
   \stoptext

It is beyond my kmowledge why the lpath
"{../pre[contains(@class,'fullwidth')]}" doesn’t return true, when
\xmlinfo shows "[code]" and \xmlpath is "doc/pre/code" (indices aren’t
relevant here).

Neither does the css selector work.

What am I missing in the lpath and the css selector?

\xmldoifelse {#1} {..[contains(@class,'fullwidth')]}

If nothing else helps, we can of course always just put that simple
script that google suggests on the website and not bother about the
results ending up on a different-looking design.

It's still better to have an ugly result page than an error page.

This can depend on the font. I just looked for another question at
cambria and it e.g. uses char + accent for some of the Umlauts. So
concrete code is needed to test this.

You are on macOS, right?

In my experience it was usually Apple's technology to blame. Perfectly
valid PDFs with proper accented characters would always end up with
decomposed characters when copy-pasting. Even pdftotext did a better
job.

I hope that Taco will be able to check this.

The token is correct, but apparently the API changed in the meantime.
Google offers some code to copy-paste that can be used directly, but
our wiki uses some strange combination of php, our own skin (written
by Siep), standalone javascript files, some html pages with results to
avoid ending up on google directly etc.

I'm lost in those files and I'm not too eager to spend too much time
learning all that stuff from scratch.

If there are any web technologies experts willing to take a look, I
can provide some source snippets offline.

Ahoi,

I’ve one annoying problem with ConTeXt: all üs (small u umlauts) seem
to be encoded as decomposed unicode or something like that, at least
every ü breaks into u + garbage if I copy some text from a ConTeXt PDF
to an app that doesn’t really support Unicode.
All other characters within Latin-1, including umlauts, are no
problem, that’s why I think the problem might be in ConTeXt’s font
handling.



it depends on

(1) what the font does, some fonts decompose and overlay base and mark 
and some fonts don't have the right unicodes with the marks so then 
you're toast
(2) only a few viewers support proper cut/paste (i only trust acrobat in 
that although mupdf based viewers seem to be ok too)



(Actually, this is about my invoice addresses that I copy from PDF to
the German Post postage webshop. The site is quite new and I can’t
understand how a big company can buy such crappy software. I already
complained, there are more problems, but of course got only a template
answer.)

Greetlings, Hraban

Hello Hans,
The macro you wrote to draw the arrows of the vectors does not seem to
work anymore.
Thank you

Re: [NTG-context] Fwd: Questions about creation of PDF's

[Hans Hagen]

Hi all,

I came across the following changes in behaviour of compilation. Using
this minimal example

\starttext
\pdfminorversion=3
Hello!
\stoptext

I found out that since TL2010 till TL2015, the output PDF is of the version 1.3
whereas TL2016 (which I do not use), TL2017 and current ConTeXt from the
garden produce PDF of version 1.7.

Is there any other (or new) way how to set the output version directly
on the source file?

Simultaneously, I found out that the produced PDF by older version -- since
TL2010 till TL2015 -- contains, e.g.,

"Creator:  ConTeXt - 2015.05.18 12:26"

whereas  TL2017 and current ConTeXt contains very short information

"Creator:  LuaTeX + ConTeXt MkIV"

Is possible to extend this information adding the date&time of the
ConTeXt, similarly to the older ones?

Many thanks in advance,

Tomáš

use something like:

\setupbackend
  [format=pdf/x-1a:2001]

\starttext

test

\stoptext

when a level is changed much more has to change and just flippign a low 
level counter is not enough then (most low level \pdf* commands are 
no-ops in mkiv, some have an implementation that hooks into other code)


in principle we can support pdf 2.0 too (luatex is already adapted) but 
we have no predefined 'formats' for that


Hans
