The Brill fonts don’t work either (http://www.brill.com/about/brill-fonts).

\resetreplacements

Both Alegreya and Brill don’t replace the ligature with a single glyph,
but replace the first glyph (only, as far as I know).
I don’t know which is the way to solve it, but this might be the cause.
Just in case it helps,

[NTG-context] issue with external image and PDF/A-3a
Dear list,
I have this minimal sample:
\setupbackend
[format=PDF/A-3a,
intent=sRGB IEC61966-2.1,
profile={sRGB.icc,default_gray.icc},
level=0]
\setuptagging[state=start]
\setupcolors[cmyk=no]
\startTEXpage[offset=1em]
\externalfigure[transparent]
\stopTEXpage
\stoptext
The external figure is available from
http://pdf.ousia.tk/transparent.pdf (and output file at
http://pdf.ousia.tk/transparent-pdf-a-3a.pdf).
Using veraPDF (http://verapdf.org/), the output document doesn’t comply
with the validation profile requirements.
As Luigi wisely predicted, external images may be problematic.
I get one error, because of the color of the external figure:
https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and-3-rules#rule-6243-2.
The PDF object in question is the following:
12 0 obj

/Type /XObject
/Subtype /Form
/FormType 1
/BBox [ 0 0 316.896 215.5669 ]

q
0.188235 0.392157 0 rg /a0 gs
28.348 187.219 260.203 -158.871 re f
Q
endstream
endobj
Well, this is a minimal sample, but my real document is much bigger. Is
there any way to convert the stream to something that ConTeXt can handle
directly?
Many thanks for your help,
Pablo

Dear Hans (and others),

still too big, at least if one uses the upright version. Judge yourself
from the example file at the end of this email (result attached).
well, normally i don't care too much about it as it's a font design
property and a designers choice
I made a bug report (see
https://sourceforge.net/p/stixfonts/tracking/95/) but Ulrike Fischer
said that it could take time to get it fixed, and that you Hans made a
fix for another bug (https://sourceforge.net/p/stixfonts/tracking/86/)
in the fontloader.
Can you do that for this one as well?
During the discussion Harald Hanche-Olsen came up with the following
"quick fix" for LuaLaTeX:
\usepackage{luatexbase,luacode}
\begin{luacode}
local patch_stixmath = function (fontdata)
if fontdata.psname == "STIXTwoMath"
then
fontdata.characters[983352]["italic"]=3*fontdata.characters[983352]["italic"]

end
luatexbase.add_to_callback
(
"luaotfload.patch_font",
patch_stixmath,
"change_stixmath"
)
\end{luacode}
I don't know if this is the way to go, but I thought I should include it.
no it's not the way to go (in context) but i cannot speak for latex

i'll add (hopefully robust) patch code to the goodie file
also, i noticed that there's more wrong with stix2 (i bet that that
would not have happened if the font was made by the gyre folks as they
have a bit more consistent workflow), so i added

% \definefontfeature[mathextra][mathextra][fixitalics=true]
to the next beta, not enabled by default because one never knows what
side effects occur

With pdftex it does avoid ligatures, but not reliably. There are

hyphenation points.
in traditional tex hyphenation is integrated in the par builder which
comes after ligaturing and kerning and tex only hyphenated where it
'makes sense' and in the process (multi-pass, going into disc nodes) it
will consult (deconstruct / reconstruct) ligatures and at that point
it's not known that the input had a {}. Tricks like inserting something

This is indeed font dependent. These binoms use a low level tex
primitive that uses a threshold for steps and that one is part of
the math parameters of a font and these are not that good for lm. As
I'm looking into some other low level side effect I was in the mood
for a configuration option for \setupmathfractions.
So, in the next beta you can get the effects iof the attached:
- relate the threshold to the bodyfont size

try to wikify it when I have tried it out. Also lucida looks better than
latin modern does at the moment.
I am a bit confused about the different versions. I would have guessed
that there was \tbinom and \dbinom and that \binom used one of them
depending on if one is in text mode or in display mode (just as I would
expect \frac to behave like \tfrac in text mode and \dfrac in display
mode). But \tbinom looks very different from \binom in text mode (with
more vertical space). Is this on purpose? Have I missed something?
One can configure those things but the absense of rules and presence of
fences matters too (all kind of inter-this-or-that and
above-below-this-or-that playts a role).

This is indeed font dependent. These binoms use a low level tex
primitive that uses a threshold for steps and that one is part of the
math parameters of a font and these are not that good for lm. As I'm
looking into some other low level side effect I was in the mood for a
configuration option for \setupmathfractions.
So, in the next beta you can get the effects iof the attached:
- relate the threshold to the bodyfont size
- use normal left/right fences instead
fwiw, cambria and pagella look better too. Upto you to wikify it.

Hi Brian,
footnotes in the wiki are tricky:
\starttext
\startbuffer
\bTABLE[split=repeat,align=normal]
\bTR\bTD Something\postponenotes\footnote[x]{bla bla}\eTD\eTR
\bTR\bTD Foo\note[x] \eTD\eTR
\eTABLE
\flushnotes
\stopbuffer
\getbuffer
\startTEXpage[offset=1em]
\getbuffer
\stopTEXpage
\stoptext
The second page is similar to the problem with the wiki.
This might be a workaround for the wiki (if I’m not wrong):
\setupnotes[location=text]
\starttext
\bTABLE[split=repeat,align=normal]
\bTR\bTD Something\postponenotes\footnote[x]{bla bla}\eTD\eTR
\bTR\bTD Foo\note[x] \eTD\eTR
\eTABLE
\flushnotes
\placenotes[footnote]
\stoptext
Just in cases it helps,
Pablo

[NTG-context] (again) issues with typing
Dear list, sorry for insisting, but I need to solve this. I have to explain to newcomers (in my Spanish introduction to ConTeXt) what comments are and multiple lines don’t affect the final PDF document. I have the following sample: \setuptyping[lines=yes] \starttext \startTEXpage[offset=1em] \startTEX This is text. % and this is a comment \stopTEX \startXML This is text. \stopXML \startLUA if code=="code" then --this is a comment --[[ this is a multiline comment --]] ---[[ this isn’t a multiline comment --]] \stopLUA \stopTEXpage \stoptext I have three questions: 1. How do I enable that multiple blank lines are displayed as more than a single one? The Lua code contains one, two and three blank lines and they are displayed always as separation from single lines. I thought lines=yes should do that, but it doesn’t. 2. I accidentally discovered that the block comment opening (--[[) removes break with next line. I think it should be fixed. 3. The most important issue is that the whole comment (both markers and content) is displayed with \darkyellow. I wonder why comments aren’t display in typing as in any other editor. All comment characters should be displayed the same, since none of them would affect to the final output. How can I get the same color for the whole comment (again, both markers and content)?

[NTG-context] comment colors in \typebuffers
Hans, I have the following sample: \starttext \startTEXpage[offset=1em] \startTEX This is text. % and this is a comment \stopTEX \startXML This is text. \stopXML \startLUA if code=="code" then --this is a comment --[[ and this is a multiline comment --]] \stopLUA \stopTEXpage \stoptext All comments are colored in darkyellow, but the issue is that in Lua and TeX only the comment markers are colored, while in XML only the comment content is colored. Because it is basic to display what it won’t affect to the interpretation or compilation of the code, would it be possible that the whole comments (both markers and content) could be colored? Sorry, but in all the code editors I have used in my life, comment coloring involved both markers (or delimiters) and content.

In Latin Modern italics (and TeX Gyre typefaces), the “ffi” ligature
isn’t added.
With EB Garamond, italics don’t get the “ffl” ligature.
The previous beta from 2017.07.27 16:17 doesn’t have the issue that I
describe.
Could anyone be so kind to confirm the bug with latest beta?

[NTG-context] inline code in XML
Hans,
many thanks for having added \xmlprettyprinttext to ConTeXt.
I have now another problem with inline code:
\definetype[TeX][option=TEX, lines=hyphenated]
\starttext
\startTEXpage[offset=1em]
This is inline code: \TeX{\command[option=value]{final text}}
\startXML
Inline code: \TeX[option=value]{final text}
\stopXML
\stopTEXpage
\stoptext
I need the \TeX command from the first text paragraph, but I have to
make it work with an XML source such as the second one (the code element).
Would it be possible to have something like \xmlprettyinlinetext (it is
essential to have consistent marking in code blocks and in inline code?
I have tried to find out a solution, but \typebuffer requires a separate
paragraph (or I didn’t know how to disable it).
Many thanks for your help,
Pablo

I was too quick. The example
\setupbodyfont[lucidaot,10pt]
\setupmathematics[stylealternative={calligraphic}]% to get the normal
math lower case italic
\startTEXpage[offset=3pt]
$f'(x)\hat{f}'(x)$
\stopTEXpage
gives bad result in both cases. The first one with wrong size and
wrong vertical placement, the second one only with wrong vertical
placement (that was not obvious to me for latin modern).

Again, thanks.
In 2017.06.06 13:22 something is still not correct.
The input file
\startTEXpage[offset=3pt]
$f'(x)\hat{f}'(x)$
\stopTEXpage
gives the attached output. The prime of f'(x) looks wrong, the one of
\hat{f}'(x) looks correct.

Hans,
maybe the \setupmathradical[sqrt][alternative=default] was not so
successful after all. Or maybe this is a bug:
%%% start of test file
\setupmathradical[sqrt][alternative=default]
\starttext
\startformula
\sqrt{1+\Bigl(\frac{f(x_k)-f(x_{k-1})}{x_k-x_{k-1}}\Bigr)^2}
\stopformula
\stoptext
%%% stop of test file
The numerator looks too small in my opinion. Compiled with 2017.06.06 13:22.

Hi,
this might be a matter of taste.
look at the output of (attached). In my opinion the first square root
is to "high", while it looks better on the second line. From
setup-en.pdf it looks like the default of \setupmathradical is set to
normal (and not default). I don't understand what normal should mean,
but I think the alternative=default looks better. (The lucida fonts
are loaded in this example, since the effect is more clear for them).

Thank you Hans, that works.
Is there also a similar way to use the "kernpairs" instead of "kerns"?
I get no effect, even after adding force = true and
\enabledirectives[fontgoodies.mathkerning].

a way to change the kerning between certain characters in mathematics
(in case one is not happy with the output from the font)? After

you can also play withj:
return {

mathematics = {
kerns = {

force = true,
topright = {
{
kern = 1000,

bottomright = {
{
kern = 1000,

},
},
},
},
}
currently you need to enable this:
\enabledirectives[fontgoodies.mathkerning]
keep in mind that some cambria (not all) have such staircase kerns which
is why force is needed in order to overload
\startluacode
fonts.handlers.otf.addfeature {
name = "kerntest",
type = "kern",
data = {
[0x61] = { [0x62] = -150 }, -- a and b in text
[0x1d44e] = { [0x1d44f] = -150 }, -- mathematical italic small a and b
[0x02032] = { [0x00028] = -150 }, -- prime and left parenthesis
}
}
\stopluacode
\definefontfeature[kerntest][kerntest=yes]
\definefontfamily[lucidaopentype][rm][Lucida Bright OT]

\startTEXpage[offset=3pt]
abba $abba f'(x)$
\addff{kerntest}
abba $abba f'(x)$
I prefer $f'\mkern-3mu(x)$
\stopTEXpage
The output is attached as a png file. As you see the kerning works as
expected in text mode, but not at all in math mode, even not for the a
and b (which I hope I entered correctly).
Something like the third line is what I'm after, but not having to use

Thank you very much for your reply, Mathias!
I'm not sure I get it, though. I find that there is already a file
lucida-opentype-math.lfg in the distribution.
Just experimenting, I added to this file an entry with kernpairs (see
below), to see if I could make a change with a and b (if I cannot
manage that, I don't see how I could get the prime and parenthesis
case to work).
%%% start of my new lucida-opentype-math.lfg
- kern_250 = { bottomright = { { kern = -250 } }, force = true }
return {
name = "lucida-opentype-math",
version = "1.00",
comment = "Goodies that complement lucida opentype.",
author = "Hans Hagen",
copyright = "ConTeXt development team",
mathematics = {
alternates = {
italic = { feature = 'ss01', value = 1, comment =
"Mathematical Alternative Lowercase Italic" },
arrow= { feature = 'ss02', value = 1, comment =
"Mathematical Alternative Smaller Arrows" },
operator = { feature = 'ss03',
Re: [NTG-context] Change kerning between math characters (prime and left parenthesis)
Hi Mikael,
math fonts are a bit different from text fonts. This means that you need
special methods to influence them. Because I once had a similar concern like
you I asked Hans to implement a way to influence kerning in math fonts between
certain glyphs. I have attached an lfg-file that shows how to use it.
To enable a goodie file like the one attached you have to define your
typescript like
\starttypescript [\s!math][cambriaown][\s!all]
\loadfontgoodies[cambriaown-math]
\definefontsynonym[\s!MathRoman][Cambria-Math]
[\s!features={\s!math\mathsizesuffix},\s!designsize=\s!auto,\s!goodies=cambriaown-math]
\stoptypescript
I hope this helps!
Best
Mathias
cambriaown-math.lfg

[NTG-context] Change kerning between math characters (prime and left parenthesis)
Hi!
Now that the bug with primes is fixed in ConTeXt, I wonder if there is
a way to change the kerning between certain characters in mathematics
(in case one is not happy with the output from the font)? After
reading in fonts-mkiv.pdf this is what I came up with:
\startluacode
fonts.handlers.otf.addfeature {
name = "kerntest",
type = "kern",
data = {
[0x61] = { [0x62] = -150 }, -- a and b in text
[0x1d44e] = { [0x1d44f] = -150 }, -- mathematical italic small a and b
[0x02032] = { [0x00028] = -150 }, -- prime and left parenthesis
}
}
\stopluacode
\definefontfeature[kerntest][kerntest=yes]
\definefontfamily[lucidaopentype][rm][Lucida Bright OT]
\definefontfamily[lucidaopentype][mm][Lucida Bright Math OT]
\setupbodyfont[lucidaopentype,10pt]
\startTEXpage[offset=3pt]
abba $abba f'(x)$
\addff{kerntest}
abba $abba f'(x)$
I prefer $f'\mkern-3mu(x)$
\stopTEXpage
The output is attached as a png file. As you see the kerning works as
expected in text mode, but not at all in math mode, even not for the a
and b (which I hope I entered correctly).
Something like the third line is what I'm after, but not having to use
\mkern in all places. Is it possible?

Hi Mikael and Hans,
I can confirm that, too: Everything is working very well in the current ConTeXt
version.
Thank you very much, Hans, for quietly solving all reported issues regarding
primes!

current version: 2017.05.25 12:50
all problems I've noticed with primes seem to be gone! Now we can even
write $u''_p$ or $u_p''$.
Hans, your work and quick fix of this problem is very much appreciated!

[NTG-context] issue with annotation flags
Dear list,
I have the following code:
\setupinteraction[state=start, color=]
\enabledirectives[references.border]
\starttext
\startTEXpage[offset=1em]
\useURL[url1][http://some-url.com]\from[url1]
\stopTEXpage
\stoptext
The annotation code in the PDF file reads:
<< /Subtype /Link
/A 7 0 R /Rect [12.354 10.896 131.607 25.324]
/C [0.6 0.6 0.6]
/F 4
/Border [0 0 0.5]>>
I need to report a bug in a PDF viewer with printing the annotation (in
this case, it is only border).
The code that generates the annotation is (with some removals):
local plus = { -- /F
Invisible = 2^0, -- 1
Hidden= 2^1, -- 2
Print = 2^2, -- 3
NoZoom= 2^3, -- 4
NoRotate = 2^4, -- 5
NoView= 2^5, -- 6
ReadOnly = 2^6, -- 7
Locked= 2^7, -- 8
ToggleNoView = 2^8, -- 9
LockedContents= 2^9, -- 10,
}
I assume that /F is set to NoZoom in the sample above (bit position 4).
Acrobat displays the annotation flag set to NoZom.
The developers assume that 4 is actually the decimal conversion for a
binary number (100, actually bit position 3). So it prints the
annotation border in the sample above.
It took me a while to understand this (math is all Greek to me).
Is there a way that I can set the annotation flag in the sample above to
Print (/F 3)? (This would be unambiguous, since only a bit can be set
[11 would be an invalid flag value].)
Or am I missing something and Acrobat is misbehaving?
Sorry for such a weird request, but bug reporting has become extremely
complex these days ;-).
Many thanks for your help,
Pablo

Re: [NTG-context] Position of prime for derivatives
Hi Mikael,
You are correct, the position of \prime depends on whether there is a next
character or not after it, and it seems that this has an effect on its position
for characters having a subscript as in
$f_{1}''(x) \neq f''_{1}(x)$
$f'f''f'’'$

Hi,
I am now more confused. I tried in different fonts, and the result is
attached. The difference in height of the prime and the double prime
is confusing me. In some fonts the prime is above the double prime, in
some the other way around (the worst is lucida, which perhaps is why I
saw it in the first place). Does someone understand why this is so? Is
it the fonts that are constructed like this?

Hi Florian,
a simpler sample would be:
\mainlanguage[es]
\setupregister[language=es, method={zm, zc}]
\starttext
\startTEXpage[offset=2em]
\index{cómodo}
\index{comodos}
\index{cómoda}
\placeindex
\stopTEXpage
\stoptext
I know that "comodos" isn’t a word in Spanish. But it should be the last
word in the sorting.
> It there a way to get this result with „methods“ or would I need to

I think that sort-lan.lua might be wrong here. I explain why.
German ("de-DE") has the following code:
replacements = {
{ "ä", 'ae' }, { "Ä", 'Ae' },
{ "ö", 'oe' }, { "Ö", 'Oe' },
{ "ü", 'ue' }, { "Ü", 'Ue' },
{ "ß", 's' },
},
This is to get Umlaut-forms and eszet sorted as ae, Ae, oe, Oe, ue, Ue
and s (which I wonder whether ß shouldn’t be replaced as ss).
Austrian German ("de-AT") doesn’t contain these replacements.
Umlaut-forms are given different entries.
I guess if we need a similar behavior for Spanish, replacements of
accented glyphs should be created, such as in:
replacements = {
{ "á", 'a' }, { "Á", 'A' }, { "é", 'e' }, { "É", 'E' },
{ "í", 'i' }, { "Í", 'I' }, { "ó", 'o' }, { "Ó", 'O' },
{ "ú", 'u' }, { "Ú", 'u' }, { "ü", 'u' }, { "Ü", 'u' },
},
So you get the right word order:
cómoda
cómodo
comodos
But Hans has to confirm the issue before.
Just in case it helps,
Pablo

Even with {zm, zc} or any of the predefined methods I don’t really think it is
working completely as expected, even though the problem might just occur in
very special cases:
\setupregister[method={zm, zc}]
\starttext
\startTEXpage[offset=2em]
\index{káv}
\index{kav}
\index{káva}
\index{kava}
\index{káf}
\index{kaf}
\index{káfa}
\index{kafa}
\index{kaka}
\index{káka}
\placeindex[language=es]
\stopTEXpage
\stoptext
gives
kaf
kafa
káf
káfa
kaka
káka
kav
kava
káv
káva
though I’d think it would be correct/logical to sort:
kaf
káf
kafa
káfa
kaka
káka
kav
káv
kava
káva
It there a way to get this result with „methods“ or would I need to modify the
sort-rules?
(The example words are not Spanish, obviously, but Icelandic/Faroese, which I
am trying to correct/set up. But I’d imagine that the same would be the desired
behaviour for Spanish and languages with similar traditions, too, wouldn’t it?)
Best

[NTG-context] (again) index sorting of accented characters
Dear list,
sorry for bothering again with this issue, but I need to have indices in
my documents.
I have the following sample:
\mainlanguage[es]
\setupregister[method=default]
\starttext
\startTEXpage[offset=1em]
\index{ámame}\index{arisco}\index{ándrago}
\index{antonia}\index{antón}
\placeindex
\stopTEXpage
\stoptext
Word sorting is the following:
antonia
antón
arisco
ámame
ándrago
Right word order is:
ámame
ándrago
antón
antonia
arisco
In Spanish, as in other languages, an accented letter has no different
sorting that its unaccented counterpart.
I got the right word order adding these replacements in sort-lan.lua:
replacements = {
{ "á", "a" }, { "é", "i"}, { "í", "i" }, { "ó", "o"},
{ "ú", "u" }, { "ü", "u" },
},
Could anyone explain me whether this is the right way of doing it?
I mean, if this is the way, I have other two patches for other two
languages in which I have indices.
And if I’m wrong, I would like to know how to get right word sorting in
registers.
Many thanks for your help,
Pablo

Wouldn't it be better to define the transparency in ConTeXt and use it
for both text and drawing? Like this:
\definecolor [tred] [r=1,g=0,b=0,t=.2,a=1]
\startuseMPgraphic{T}
newpath rc; rc := fullsquare xyscaled (50mm, 50mm);
color col; col := (1.,.1,.1);

draw rc withpen pencircle scaled (2.5mm) ;
label(textext("\setupbodyfont[sans,35mm] \color[tred]{Test}"), (80mm,
50mm)) ;
\stopuseMPgraphic
\defineoverlay[T][\useMPgraphic{T}]
\setupbackgrounds[page][background={foreground,T}]
\startTEXpage[width=200mm,height=200mm]
\stopTEXpage

If I understand the code correctly (sorry, haven't tested it yet),

i prefer empty to be as before we even had factor i.e. same as auto

I think that it may be more consistent if factor= and factor=none do not
scale the delimited at all. To maintain backward compatibility, the
default value of factor can be set to auto.
Also what values of factor give scaling equal to \big, \Big, \bigg, and
\Bigg?
These values are actually somewhat weird and relate to the design size
of a font .. derived from plain:
0.85
1.15
1.45
1.75
but ... as these are extensibles a font might have more values. The
factor is n times the bodyfontsize (50% above and below the axis)
what actually comes out depends on the chosen font

When you use a math font (which Neo Euler is) the argument of the
features key
is ignored and \definefontfamily uses internal default values instead.
These default
values can only be overwritten by feature values for each alternative, e.g.
\definefontfamily[...][...][Neo
Euler][tf={style:regular,features:default}]

(I’m using latest beta from 2017.03.02 22:23.)
Is this a bug or what am I missing?
Many thanks for your help,

Maybe instead of the « delimiter » keyword, one could introduce a keyword such

with integrals we have factor as key ... anyway, i'll look into it (not

There are instances where the automatic scaling provided by \left and \right is

Currently, math fences always default to using \left and \right, which can lead
to undesirable results. For example:
\definemathfence [MEAN] [angle] [command=yes, color=blue]

\MEAN{ \sum_{i = 1}^n A_i x_i }
\hbox{ vs. }
\bigg\langle \sum_{i=1}^n A_i x_i \bigg\rangle

Could we add an option to \definefence that allows the user to select the
delimiter scaling using a key (say, `delimiter`) so that
\MEAN[delimiter=auto] expands to \left\langle .. \right\langle
\MEAN[delimiter=] expands to \langle .. \rangle
\MEAN[delimiter=big] expands to \big\langle ... \big\rangle
\MEAN[delimiter=Big] expands to \Big\langle ... \Big\rangle
\MEAN[delimiter=bigg] expands to \bigg\langle ... \bigg\rangle
\MEAN[delimiter=Bigg] expands to \Bigg\langle ... \Bigg\rangle
I am not sure whether `delimiter` is the best key. I think that `scale` may be
better, but using `scale` for specifying the scaling of math delimiters will be
inconsistent with how `scale` is used everywhere else. Another option is to use
`alternative` key.
it would be something factor=2 or so, not the funny XxXxxxXX kind of flags
Thanks,

the fact that it won't work as you expect ... in fact there is some

as it needs it hook into protrusion (be dealt with in line breaking)
But still it's useless as that font only has left W V - and right v -

Hi John,
it was a sample from me. Sorry for not having answered before.
An extended version with slanted would be:
\definefontfamily
[mainface]
[rm]
[TeX Gyre Pagella]
[it={TeX Gyre Cursor-Italic},
sl={TeX Gyre Schola-Regular, features:{default,slanted}}
bf={TeX Gyre Adventor-Bold},

\setupbodyfont[mainface]
\starttext
\startTEXpage[offset=1em]
Roman font {\em italic} {\sl slanted}
\bf Bold font \em bold italic
\stopTEXpage
\stoptext
Let me know if you miss something in the sample.

Re: [NTG-context] Comical error..
Re question 2. You can have the list of loaded fonts files from the log file
produced by context command, nearly the end :
For example from my run :
mkiv lua stats > loaded fonts: 4 files: dejavusansmono.ttf,
ebgaramond12-regular.otf, keteryg-medium.ttf, sblgreek.ttf
>From this you can deduce most probably the font file format.
Please use :
mtxrun --script fonts
To get more information on fonts database context uses.
Hope this helps a bit.

Hans,
I totally agree.
The point I was trying to make is that ungrouped font size switches
behave different if when fixed and when not fixed.

Hi Thomas,
I must confess, I haven’t checked the manual. But why doesn’t it happen
the same with other commands?
\starttext

looks quite ok to me ... grouping works as expected

Dear list members,
I create all my MetaFun drawings in a separate environment file where
each individual drawing sits inside a start/stopbuffer. This allows me
to easily use those drawings in all my documents using
\processMPbuffer[name]. Works just fine.
However, I also wish to have all the drawing available in a pdf file
(each drawing on a separate page). This allows me to split the pdf and
use the drawing elsewhere (e.g. in a Powerpoint) or include page(s)
from the pdf in another document.
The below MWE represent my MetaFun drawings file.
The idea is that by uncommenting the \enablemode[makepdf] I can create
the pdf file with drawings. It seems however that startMPpage does not
accept buffers (I also tried processbuffer and processMPbuffer).
Is it possible to somehow make this work?
You can use
\startTEXpage
\processMPbuffer[…]
\stopTEXpage
but loading a buffer in MPpage doesn’t work because the content of the
environment
is just passed to MetaPost and buffers can’t be loaded inside MetaPost
code unless
Hans adds a function for this, e.g.
\startMPcode
buffer("mybuffer")
\stopMPcode

You can use offset the control the padding on all four sides and loffset

[NTG-context] Size of the last shipped page by Lua?
Hello,
is there a way to detect by Lua what is the size (width and height) of the last
shipped page?
Especially I'm interested in the situation when page via \start/\stopTEXpage
has been shipped, like:
\startluacode
LastPageSize = function()
-- What to come here?
return w, h
end
\stopluacode
\starttext
\startluacode
local w, h = LastPageSize()
context("w="..w .. ", h=" ..h) -- Should give "w=210mm, h=297mm" (or other
units)
\stopluacode
\startTEXpage[with=10cm,height=15cm]
\stopTEXpage
\startluacode
local w, h = LastPageSize()
context("w="..w .. ", h=" ..h) -- Should give "w=100mm, h=150mm" (or other
units)
\stopluacode
\stoptext
This would be very useful when I need to insert a page of size of the last page
to move to odd page when A4 and A3 pages are mixed, to allow simple duplex
printing on the printer.
So - how about 'LastPageSize()' function?
Best regards,
Lukas

[NTG-context] Header background off with \page?

The \page[yes,header,footer,odd] suppress header and footer, which is good, and inserts one page; the problem is that header and footer background is kept and still appears. Is it a "wanted" feature? My guess is that when one uses "\page[...,header,footer...]" than suppressing header/footer background is intended, too. If the background is not suppressed automatically with "header,footer", would it be possible to implement something like "\page[...,background,...] which would suppress header and footer background (or suppress their backgrounds automatically with \page[...header...footer...])?

Adding \usecolors[xwi] to the example does not change anything. Looking
at base/colo-imp-xwi.mkiv revealed, that it does not alter the way
colors are defined, but just defines a huge bunch of additional ones.

I'm very sorry for the confusion. What I did was to adjust ConTeXt's
gray to have the same grayscale value as the tikzgray. As is shown
below, the redefinition of gray does not propagate to TikZ.

In pgfutil-context.def there is though
\let\pgfutil@registergray \pgf@context@registergray
So it seems as if gray *should* be propagated from ConTeXt to TikZ,
which apparently takes place when loading TikZ. Moving
\definecolor[gray][s=0.5] before \usemodule[tikz] shows this behavior.
The question is how to keep colors from ConTeXt and TikZ in sync.

Dear Aditya and Hans,
I'm not so sure about it being a bug in pgfplots. I played a little and

As Aditya pointed out, these (probably used for tracing) colors are
defined in such a way that they don't go via the context resolver. As
these (few) colors are basically x windows colors, you can start your
document with:
\usecolors[xwi]
which will set the context colors differently.
\usemodule[tikz]
\starttext
% Original gray
\blackrule[color=gray,width=1cm,height=1pt]
\starttikzpicture
\draw[gray,line width=1pt] (0,0) -- (1,0);

\definecolor[gray][s=0.5]
\unprotect
\pgfutil@definecolor{tikzgray}{gray}{0.5}
\protect
% Now ConTeXt's gray = tikzgray
\blackrule[color=gray,width=1cm,height=1pt]
How is that supposed to work? Context will not inherit colors from tikz,
the most you can expect is the reverse: tikz using context color
definitions.
\starttikzpicture
\draw[tikzgray,line width=1pt] (0,0) -- (1,0);
\stoptikzpicture
% Inside TikZ gray is still off
\starttikzpicture
\draw[gray,line width=1pt] (0,0) -- (1,0);

If I add

Can you comment on the phrase »no need for x colors (users can load it

there exists a proper solution to my color problem.
normally you want the same colors in tikz images as in context so then

I guess it is a bug with pgfplots rather than tikz (which also means
that it may be easier to pursuade pgfplot maintainers to use low level
tikz interface, since tikz is already playing nice with context).

Perhaps, one could define a macro `\enabletikzcolors[...list..]` that

[NTG-context] beta
Hi,
I uploaded a new beta. This version has (experimental) support for color
fonts. (not to be confused with 'coloring text in a font').
\definefontfeature[svg][default][svg=yes]
\definefontfeature[colored][default][colr=yes]
% \definefont[Emoj][file:emojionecolor-svginot.ttf*default,svg]
% \definefont[Emoj][file:seguiemj.ttf*default,colored]
\definesymbol[bug1][\getglyphdirect{file:emojionecolor-svginot.ttf*svg}{\char"1F41B}]
\definesymbol[bug2][\getglyphdirect{file:seguiemj.ttf*colored}
{\char"1F41B}]
\startTEXpage [width=10em,align=middle,offset=1em]
There are several kind of bugs, like \symbol [bug1] and \symbol [bug2],
also in \CONTEXT !
\stopTEXpage
The colr features uses (if present) the overlay method (microsoft fonts
have that) which is quite clean and efficient, while the svg one uses
(when present) svg information from the font. Caching the later one will
take some initial time (due to conversion, i might figure out something
better) and needs inkscape installed.
Attached an example. I didn't look too extensively for a font, but on
the agenda is turning the cowfont in a color one (maybe for the ctx
meeting). At some point I might add overloading of colors (for the
overlay variant).

Re: [NTG-context] Incorrect math kerning
Hi Aditya,
This is based on a question about latex on tex.stackexchange:
http://tex.stackexchange.com/q/312098/323
but context shows the same behaviour.
The subscript "i" in the following example is kerned incorrectly (it is
too far away from W). Is this a bug in the font, or with the fontloader?
\setupbodyfont[cambria]
\starttext
\startTEXpage[offset=2mm]
$W_i^i$
\stopTEXpage
\stoptext
The next beta fixes the scaler but of course that leaves fonts untouched.
However, as a test I added some more lfg files that implement the V and
W cutins for some fonts. Beware: the lm / gyre fonts are in the process
of being updated which means that kerning will change (and therefore
also the rendering) later this year. After that we can still decide to
ship variants. For now it's directive driven.
\enabledirectives[fontgoodies.mathkerning]

{\hbox to 50pt{\hss\showboxes\switchtobodyfont [schola]$V_i^i

A bit of a playground for deciding om where to draw the limit.

In traditional TeX fonts italic correction is used as a kind of kerning.
This happens in combination with cheating with the width of glyphs. This
is somewhat reflected in the lm fonts (with some inconsistencies between
for instance V and W ... we're currently discussing this). So, a way to
force a subscript towards the shape is to use less width, and then use
italic correction to move the superscript the other way. Of course this
kind of kerning is a bit of a cheat and not related to italic shape
(some upright characters also have italic corrections).
In cambria staircase kerns are used for this but they are not defined
for all (base) characters. The gyre fonts don't cheat on the width.

Once the math fonts are stable and frozen I'll come up with a solution
(in ConTeXt) for this. Luatex < 0.85 had a mixed code path for dealing
with italics (adding them always and removing them selectively) but as
the standard is not more explicit about where to apply italic correction
these code paths have been separated.
In ConTeXt we had some italic correction juggling (basically i disabled
passing them to the engine and applied them selectively) but because lm
/ rest of ot is not consistent it never was satisfying.

[NTG-context] uppercase, small caps, numerals and German capital sharp s
Hello,
I'm new to ConTeXt and this list. After a long time of using LaTeX and
xeLaTeX I was finally lured into trying ConTexT by its ability of grid
typesetting.
Today's problem is a bit complex. In a book project I have several
points where stuff is capitalized or turned into caps+smallcaps or pure
smallcaps. My guess is that that should work either with \WORD{Stuff},
\Cap{Stuff} and \cap{Stuff} or with \uppercase, \sc, and
{\sc\lowercase{Stuff}}. (Not quite, it seems)
I'll use a commercial font called Calluna, but have added Linux Biolinum
O to the example for those who don't want to download Calluna (the
"Regular" can be "bought" for free, e.g. at
https://www.fontspring.com/fonts/exljbris/calluna).
Both Calluna and Biolinum contain the glyph "LATIN CAPITAL LETTER SHARP
S" at "1E9E. I'm not sure if they contain a small or medium caps
version. I'd like to use that glyph in the capitalizations mentioned,
but it only works erratically (cf. example).
Also, Calluna comes with oldstyle numerals switched on, which is nice
for normal text, but should change to lining numbers in all-caps and to
small-cap lining numbers in all-small-cap text. I'm not sure what I'll
want in a caps+smallcaps context, but certainly not oldstyle numbers
with their descenders.
Any ideas? Thanks for reading! -- Thomas
PS: I asked the same question on stackexchange, there's also an image of
the result of my example:

[NTG-context] uppercase, small caps, numerals and German capital sharp s
Hello,
I'm new to ConTeXt and this list. After a long time of using LaTeX and
xeLaTeX I was finally lured into trying ConTexT by its ability of grid
typesetting.
Today's problem is a bit complex. In a book project I have several
points where stuff is capitalized or turned into caps+smallcaps or pure
smallcaps. My guess is that that should work either with \WORD{Stuff},
\Cap{Stuff} and \cap{Stuff} or with \uppercase, \sc, and
{\sc\lowercase{Stuff}}. (Not quite, it seems)
I'll use a commercial font called Calluna, but have added Linux Biolinum
O to the example for those who don't want to download Calluna (the
"Regular" can be "bought" for free, e.g. at
https://www.fontspring.com/fonts/exljbris/calluna).
Both Calluna and Biolinum contain the glyph "LATIN CAPITAL LETTER SHARP
S" at "1E9E. Calluna also has a small caps version at "F727", while
Biolinum has it at "E092. I'd like to use these glyphs in the
capitalizations mentioned, but that only works erratically (cf. example).
Secondly, Calluna comes with oldstyle numerals switched on, which is
nice for normal text, but should change to proportional lining numbers
in uppercase and to small-cap proportional lining numbers in an
all-small-cap text. I'm not sure what I'd want in a caps+smallcaps
context, but certainly not oldstyle numerals with their descenders.
Any hints and ideas? Thanks for reading! -- Thomas
PS: I asked the same question on stackexchange, there's also an image of
the result of my example:

Re: [NTG-context] \startuseMPgraphic
Thank you Wolfgang, this is a very good explanation.
One can simplify one's code, perhaps, by defining MP colors from
ConTeXt colors, as in:
color orange ; orange := \MPcolor{orange} ;
Then, one can use orange. There is not much point in redefining the
other colors (red, green, blue, cyan, magenta, yellow, black, white) as
they are defined using the same rgb values.
In fact, \MPcolor{} simply injects "(r,g,b)" or "(c,m,y,k)" with
explicit values into the MP code.
Defining new MP colors is less general than explicitly using
\MPcolor{...}, for it is limiting, and it would be somewhat silly to
add definitions for all of the wonderful colors found in colo-imp-x11,
for example.
By the way, we added colo-imp-crayola having some funky, hallucinogenic
names (according to Hans) as well as colo-imp-ral.
(The first might be of interest to Americans and the second to
Europeans ;-)
Other collections, such as colo-imp-pantone and colo-imp-rosco are not
distributed due to copyright restrictions (but I have made private
copies, shhh!)
