Hello Wolfgang, Otared and Aditya.
Thanks for your advice and treatments. It is there a complete working 
example?
I am sorry, but I am not able to achieve the proposed modifications to

Hi Wolfgang, Hi Aditya,

Thanks for your attention.
Unfortunately adding

When you enumerations in this form

you have to finish the paragraph, e.g. by adding \par

\beginanswer

or better use the start/stop commands for the enumeration.

Two files: kpfonts-math.lfg and testfile004.tex.

It works rather well with the formulas of that file:
https://github.com/khaledhosny/euler-otf/blob/master/tests/test.tex.

Main issue: $\bf \Gamma$ produces "medium" \Gamma, though:
["kpfonts-bf"] = {...
{ name = "jkpbmia",  vector = "tex-mr", skewchar=0x7F },
should make it bold.
Why is this vector never selected?

Other issue: Two consecutive \Gamma, are overlapping a lot.

In case I add a vector for a script font which is in jkpsyd.pfb. What
font switch would be used to select this vector (vector="tex-md")?

The “regularfont”, “regularfeatures” etc. keys are going to disappear at some
point because both settings can be done with with “tf”, “it” etc. keys.

What you try can’t work because spec is one of context three methods to load a 
font,
the first two are “file:…” and “name:…”. With the spec method you give context 
a list
of features for the font you want to load, the spec specifier has 5 argument:

1. The family name of the font
2. The weight of the font (light, normal, medium, bold, …)
3. The style of the font (normal, italic, slanted, …)
4. The width of the font (condensed, normal, expanded, …)
5. The variant of the font (normal, old style or smallcaps)

When you load a font you separate all arguments by a hyphen, when you leave
arguments out they get normal as default values. Below is a example how to load
TeX Gyre Pagella Regular and Bold with the spec method:

\starttext

{\definedfont[spec:texgyrepagella-normal]TeX Gyre Pagella Regular}

{\definedfont[spec:texgyrepagella-bold]TeX Gyre Pagella Bold}

\stoptext

When you want now the bolditalic form of the font you have to set the third 
argument
for the style:

\starttext

{\definedfont[spec:texgyrepagella-bold-normal]TeX Gyre Pagella Bold}

{\definedfont[spec:texgyrepagella-bold-italic]TeX Gyre Pagella Bolditalic}

\stoptext

When you now use the spec method with \definefontfamily nearly the same thing
happens but you set only the argument 2–5 because the name of the font was
already set.

Just avoid the spec method, it depends a lot on the information in the font
and is not always reliable, because of this I don’t use it as default method
to search for all files in a font family.

[NTG-context] Fallback for mathematical lowercase h and hyphen

[Joshua Krämer]

Dear list!

(1) With the following example, only manually inserted hyphens are
replaced. How can I replace the hyphen automatically inserted at
linebreaks?

\definefontfeature[extended][default][extend=3]
\definefallbackfamily[mainface][serif][TeX Gyre Termes]
[range={0x0002d}, features=extended]
\definefontfamily[mainface][serif][Latin Modern Roman]
\setupbodyfont[mainface, 30pt]
\starttext
line-break \dorecurse{100}{linebreak }
\stoptext

I have added the feature "extended" only for better distinction.


(2) In the following example, the lowercase h is not replaced. I think
this may be because it is separately encoded as "Planck
constant" (U+210E) in math fonts.

\definefontfamily[mainface][serif][Latin Modern Roman]
\definefallbackfamily[mainface][math][Latin Modern Roman]
[preset=math:lowercaseitalic]
\definefontfamily[mainface][math][TeX Gyre Termes Math]
\setupbodyfont[mainface, 30pt]
\starttext
$ abch $
\stoptext

Joshua Krämer

With the initial patch I had sent, these were working okay (ie, akhn,
pref, pstf and blwf ligatures were being formed).
Minimal character sequence for test case:
\char"0D26 \char"0D4D \char"0D26 \char"0D47%% 
needs to form 

With initial patch, in "methods.dev2", (syllablestart,syllableend)
were: (0D26, 0D26) {cluster DA, VIRAMA, DA} and (0D47,0D47) {E}.
Current beta gets (0D26,0D4D) {cluster DA, VIRAMA} and (0D26,0D47)
{DA, E}. Something changed in "analyze_next_chars_two", may be?

Okay - found that you had not considered 0D4D (virama/halant) not as
"halant{}" but as "stress_tone_mark{}". Adding 0D4D to the array
"halant{}" restores the previous behaviour - ligatures are formed but
with issues mentioned in the initial mail. "analyze_next_chars_two"
indeed looks for halant.

I've got the values from the output of "mtxrun --script fonts --list
--all --pattern=xxx" (and compared with the name/style values in
Fontforge), so I don't understand why "spec:roman1" works, but
"spec:italic1" doesn't.

Additionally, what I think must be a bug is that
"italicfont=file:xxxitalic1, boldfont=file:xxxroman2" works but stops
working if I add "regularfont=spec:roman1":

\definefontfamily[xxxface][serif][xxx][regularfont=spec:roman1,
italicfont=file:xxxitalic1, boldfont=file:xxxroman2]

Maybe if one of the values uses the "spec:" selector, all the values
are treated as spec values despite the "file:" selector given?

Thanks, this works.  For some reason, "tf=" works, but "regularfont="
doesn't.

And by the way, this works:
\definefontfamily[leitura][serif][Leitura News][regularfont=spec:roman2]

and this doesn't work:
\definefontfamily[leitura][serif][Leitura News][tf=spec:roman2]

So in some cases only "regularfont" seems to work, and in some cases
only "tf".

Joshua

When you set “force=yes” (default value) context uses the fallback font even
when the character exists the main font.

The name of the font files has nothing to do with way how \definefontfamily
collects the individual files for each style, to do this it uses internal names
and values from the font.

In a case where \definefontfamily can’t find all styles you can select them
with the name of the files:

\definefontfamily[][

[NTG-context] betas

[Hans Hagen]

Hi,

As some of you might have noticed, we're in transition to luatex 0.80
(currently 0.78.1). This binary is somewhat faster with respect to nodes 
without modification of Lua code, but it also provides an additional 
node field access mechanism. Luigi and I spent quite some time on 
getting that done and in the process some 70 context files were adapted 
(as we needed to test). However, it's likely that I have missed some 
needed changes. As both access mechanisms cannot be mixed, one has to be 
consistent in usage. Also, the somewhat faster (new) usage is more 
sensitive for errors so it has to be used with robust (proven) code 
(read: pluggable code can best use the traditional node field accessors 
which also have been sped up). And of course it only makes sense for 
very demanding cases (as stock luatex is already rather efficient now), 
think of devanagari (where we can get 50% faster) and complex arabic 
(some 25%). As ConTeXt spends > 50% of its time in Lua it might make a 
difference in other places too.


Anyway, for instance the 175 fonts-mkiv manual processes 10% faster due 
to this and sometimes more can be achieved (it really depends on how 
much Lua enhanced mechanisms are used). Roughly I get on my win 8.1 64 
bit laptop for the font manual:


10sec luatex0.77 with previous context code base
10.25 sec luatex0.77 with current context code base
 9.00 sec luatex0.78 with current context code base
 7.50 sec luajittex 0.78 with current context code base

(This manual loads quite some fonts in the process.)

In case you wonder why speed is an issue: it really matters when tex is 
used as a service, and I like fast edit-test cycles too. The target is 
to get 20 pps or more even for complex documents. It's not that hard to 
get 550 pps for simple 1000 page one-word-per page documents but when 
much more kicks in we quickly drop to 15-20 pps.


Also, Luigi and I also want to reach reasonable speeds on android phones 
(triggered by Harald's experiments at the context meeting) but that's 
another topic.

When you enumerations in this form

\beginanswer
\answer $10$
\endanswer

you have to finish the paragraph, e.g. by adding \par

\beginanswer
\answer $10$\par
\endanswer

or better use the start/stop commands for the enumeration.

\beginanswer
\startanswer
$10$
\stopanswer
\endanswer

That's the difference between Word and Words so it is intentional.

Re: [NTG-context] setuphead for in-paragraph head ?

[Otared Kavian]

Hi Wolfgang, Hi Aditya,

Thanks for your attention.
Unfortunately adding 
\keepblocks[question] 
the example I sent before does not work in mkiv, and changing 
location=hanging
to
alternative=hanging
does not help neither…
The error message in mkiv is:
\dostopnormalblock ...meter \c!after \par \egroup 
  
 ...fact that $2\times 5 = 10$. \dostopnormalblock 
  \dostartnormalblock {hint}...
\dodowithpar ...dler \v!construction \endcsname #1
  \csname \??constructionsto…

So I don’t know what to do if one has to use mkiv.

Best regards: OK

in fact we found that --jiton is slower ... just use --jit and benefit

gets obscured by the fact that the vm is twice as fast); i guess that 
the context lua codebase is too large to benefit from jit and also 
hardly uses jitabble built-in functions (much if that is hardcoded in 
jit) and the amount of calls is too low to trade off jitting and using 
(we don't do number crunching or have applications running for more than 
a few seconds)

Re: [NTG-context] setuphead for in-paragraph head ?

Hi Jean Guillaume,

I guess Marco Patzer and Wolfgang Schuster gave you already the appropriate 
answers.
Nevertheless, I wanted to share with you the definitions I use for the kind of 
work you want to do:

%%% begin example-exercise.tex

% defining \startexo, \stopexo as an enumeration:
\startsetups style:simple
\defineenumeration[exo]

Re: [NTG-context] setuphead for in-paragraph head ?

[Jean-Guillaume]

But this:

\definehead
  [Exercise] [subsection]
  [after=]
\starttext
  \startExercise [title=This is the exercise's title]
The exercise's content.
  \stopExercise
\stoptext

results to:

1 This is the exercise's title
The exercise's content.

and I would like it to be:

1 This is the exercise's title The exercise's content.

(When I can typeset that, I will see about formatting the number and so on.)

I'm sorry it wasn't very clear. Now I understand that I misunderstood
\startExercise{...} for \startExercise[title=...] and that's why I was
confused about which newline I want to get rid of.

Re: [NTG-context] setuphead for in-paragraph head ?

Thanks for your reply, Marco.

Here is a full example:

 \starttext
 \definehead[Exercise][subsection]
 \setuphead
[Exercise]
[after=]
\startExercise[]{(this is the exercise's title)}
The exercise's content.
\stopExercise
\stoptext


After contexting it, it looks like:

1
(this is the exercise's title) The exercise's content.


Actually, I would like to have the head's number and the head's title
on the same line. That is, whith no new line.

Re: [NTG-context] latest beta and luajittex in Linux 32-bit

Indeed the binary doesn't even work on the same machine where it has
been compiled. Sorry for that. I get the following error:

> luajittex --version
luajittex: /lib/libc.so.6: version `GLIBC_2.3.4' not found (required
by luajittex)
luajittex: /lib/libc.so.6: version `GLIBC_2.7' not found (required by luajittex)
luajittex: /lib/libc.so.6: version `GLIBC_2.11' not found (required by
luajittex)

I added Alan's binary now, but I currently don't have a suitable linux
box to test whether it works.

On top of that I forgot to fix the auto-update script to fetch the
latest binaries (again I have an appropriate person to blame for
making me upgrade the SVN repository to the latest version, even
though that didn't really solve the problem with apparently
broken/buggy SVN ;).

\setcharactercasing requires a new paragraph to work. Seems like a

That's controlled by the “after” key.

 \setuphead

  [after=]

Please provide full working examples next time. That makes it easier
for us and it's more likely you'll get a response.

That depends on your document. You can use sections, enumerations or
Wolfgang's annotation module.

I've read in another mail that force=yes is now set by default, so this

Re: [NTG-context] Mixing math and text font

[Joshua Krämer]

Thanks for your hard work!  I have a few additional questions regarding 
the new system and font fallbacks.


(1) How can I replace the hyphen automatically inserted at linebreaks?  
If I use the following, only manually inserted hyphens are replaced:

\definefallbackfamily[mainface][serif][TeX Gyre Termes][range={0x0002d}]


(2) What effect does force=yes have?  It doesn't seem to make a 
difference for me.


(3) I have a typeface that uses unusual style names: "roman1", "roman2", 
"italic1", "italic2";  1 is regular, 2 is bold weight.  The following 
works:

\definefontfamily[xxxface][serif][xxx][regularfont=xxxroman1, 
italicfont=xxxitalic1, boldfont=xxxroman2]
\setupbodyfont[xxxface]
\starttext
abc {\it abc} {\bf abc}
\stoptext

This works for roman1 only:

\definefontfamily[xxxface][serif][xxx][regularfont=spec:roman1, 
italicfont=spec:italic1, boldfont=spec:roman2]

Even this works for roman1 only:

\definefontfamily[xxxface][serif][xxx][regularfont=spec:roman1, 
italicfont=xxxitalic1, boldfont=xxxroman2]


(4) Now I want to use this typeface for math fallback.  In the following 
example, the upright glyphs are replaced, but not the italic glyphs:

\definefontfamily[xxxface][serif][xxx][regularfont=xxxroman1, 
italicfont=xxxitalic1, boldfont=xxxroman2]
\definefallbackfamily[xxxface][math][xxx][regularfont=xxxroman1, 
preset=math:lowercasenormal]
\definefallbackfamily[xxxface][math][xxx][regularfont=xxxroman1, 
preset=math:uppercasenormal]
\definefallbackfamily[xxxface][math][xxx][italicfont=xxxitalic1, 
preset=math:lowercaseitalic]
\definefallbackfamily[xxxface][math][xxx][italicfont=xxxitalic1, 
preset=math:uppercaseitalic]
\definefallbackfamily[xxxface][math][xxx][regularfont=xxxroman1, 
preset=math:digitsnormal]
\definefontfamily[xxxface][math][TeX Gyre Termes Math]
\setupbodyfont[xxxface]
\starttext
$ \coprod \leftrightarrow ABC abc {\mathupright ABC abc} 123 $ 
\stoptext


Kind regards,
Joshua

[NTG-context] setuphead for in-paragraph head ?

[Jean-Guillaume]

Hi all,
this is my first message here.

In the subsection head, I would like to suppress the newline between the
number and the text, so it behaves like some kind of numbered subsubject.
I tried to modify some examples from the wiki, but without success. In
http://wiki.contextgarden.net/Command/setuphead , most of the options are
not explained.

My purpose is to define something like:

 \definehead[Exercise][subsection]
 \setuphead
  [Exercise]
  [alternative=Mine?,
  ...,
  numberstyle=bold]

So I can typeset a list of exercises in a compact way. I could use
enumerations but I don't think I should.

Thanks.
