your penalty settings allow widows and orphans, but on one particular

way to do this ?
it works per paragraph so then you need to adapt it for a specific 
paragraph


when the par starts, the properties are stored (in lmtx it's configured 
that way); you can change properties in the middle of a paragraph but 
then you need to explicitly freeze them, as demonstrated in the examples 
below; tracing will show you all stored properties


(default tex behaviour is that the last setting counts which can be 
somewhat unexpected)


\starttext
\tracingoutput1 \tracingonline1
\pretolerance9000 test \pretolerance8000 test \par
\pretolerance9000 test \pretolerance7000 \updateparagraphproperties 
test \par
\pretolerance9000 test \pretolerance6000 
\snapshotpar\frozentolerancecode test \par

\stoptext

the log shows ...

\par[newgraf][16=1,17=1],  pretolerance 9000, 
\par[newgraf][16=1,17=1],  pretolerance 7000, 
\par[newgraf][16=1,17=1],  pretolerance 6000, 

now, as you probably don't want to be persistent you can group:

\def\MyHack
  {\bgroup
   \pretolerance5000
   \snapshotpar\frozentolerancecode
   \egroup}

test \MyHack test

works ok because the snapshotting applies to the current paragraph (it's 
actually described in some manual)


so, basically, you have a lot of control, all together some 36 
parameters (pablo probably loves the somewhat secret on the fly 
adjustspacing step, stretch and shrink tweakability)

[NTG-context] Tracking overfull/underfull vboxes, widows/orphans

2021-05-10 Thread denis.maier 
Hi,
some time ago Hans has added these trackers for overfull/underfull hboxes:


I'm wondering if there is something similar for vertical boxes?
I've found these trackers:
builders.vspacing
builders.vpacking
builders.page_vspacing
builders.collect_vspacing

But I don't really understand what they do. (Yes, I've tried them.)
Maybe someone can shed some light on this ? (RTFM is a perfectly fine answer, 
just need to know which manual...)

Then, would it be possible to add a tracker for widows/orphans?  (Or even for 
prevented widows/orphans ?)

Re: [NTG-context] KeenWrite 2.0

2021-05-10 Thread Thangalin 
Running from the command-line requires the full edition of Liberica JDK,
which includes JavaFX. See:

https://github.com/DaveJarvis/keenwrite#other
https://bell-sw.com/pages/downloads/?version=java-16

Other OpenJDK versions do not include JavaFX. (JavaFX can be installed
separately for other OpenJDK versions, but it's a bit of a pain.) The
decision to remove JavaFX from the default Java distribution kind of pulled
the rug out from under a number of projects.

Re: [NTG-context] KeenWrite 2.0

2021-05-10 Thread Thangalin 
Thanks Floris.

https://github.com/DaveJarvis/keenwrite#other

That's a known issue due to Java's transition to a modular architecture. It
means that a third-party library is using reflection to access behaviour in
a Java class that was designed to be off-limits. Starting from Java 9,
these types of reflection calls have been deprecated. In this particular
case, it's fine, but this third-party library needs to be updated soon.

Cheers!

[NTG-context] underscore hyphenation and hz

2021-05-10 Thread Pablo Rodriguez 
Hans,

I’m afraid that underscore hyphenation has issues with font expansion:

  \startluacode
  function document.addfunnyhyphen(tfmdata)
  local underscore = utf.byte("_")
  local char   = tfmdata.characters[underscore]
  if not char then return end
  tfmdata.characters[0xFE000]   = {
  width= 0,
  height   = 0,
  depth= 0,
  commands = {
  { "right", -char.width },
  { "down", char.depth },
  { "slot", 1, underscore },
  }
  }
  end


  utilities.sequencers.appendaction("aftercopyingcharacters",
  "after","document.addfunnyhyphen")

  local shared = {
  start  = 1,
  length = 1,
  before = utf.char(0xFE000),
  after  = nil,
  left   = false,
  right  = false,
  }

  local all = table.setmetatableindex({ }, function(t,k)
  return shared
  end)

  languages.hyphenators.traditional.installmethod("sha",
  function(dictionary,word,n)
  return all
  end)
  \stopluacode

  \definehyphenationfeatures

  alternative=sha,
  righthyphenchar="FE000]

uninstalling a matter of removing it from the PATH and registry (on
Windows, anyway). Here are the current instructions:

Is there a way we can eliminate steps 3 - 6 for Windows installs?

This is how setuptex works on linux as well.

One of the benefits of context minimals is that you can install multiple 
versions in parallel, which allows the user to update frequently without the 
risk of breaking something for long-term projects. Specifically, you can keep a 
"frozen" version of context for long-term projects and install a newer version 
in parallel for newer projects. 

So, your suggestions should be included as a separate script and not as part of 
the default. Then there is the question of providing an uninstall script as 
well...

Re: [NTG-context] underscore hyphenation not working

It works fine now.

A minor issue happens with SumatraPDF-3.1.2 (aside from font advance):

  \setuppapersize[A6]
  \definefontfamily[mainface][rm]
  [TeX Gyre Pagella]
  \setupbodyfont[mainface]
  \starttext
\input zapf
  \stoptext

Lines 3, 7, 10, 12 and 13 lack spaces between words:

  Coming back to the use of typefaces in
  electronic publishing: many of the new
  typographersreceivetheirknowledgeand
  information about the rules of typogra-
  phy from books, from computer maga-
  zines or the instruction manuals which
  theygetwiththepurchaseofaPCorsoft-
  ware. There is not so much basic instruc-
  tion, as of now, as there was in the old

  plearejustfascinatedbytheirPC'stricks,
  andthinkthatawidely--praisedprogram,

Although this only happens with SumatraPDF, it would be great to have
standard spacing (otherwise searching is impossible).

Many thanks for your help,

Pablo
