As always, thank you.

I have updated the wiki page for setupcaptions. The updated includes a 
reworded description of the suffix key and new descriptions for the 
stopper/numberstopper and separator/prefixconnector keys.


(There are many other keys that are not documented, and a few at least 
that differ between MKII and MKIV, but I do not have the time at the 
moment to test all of them.)

Re: [NTG-context] \triangledown placed too low in Palatino

[Otared Kavian]

Hi,

The \triangle operator is used for instance in the « symmetric difference » of 
two subsets: if $E$ is a set and $A \subset E$, and $B \susbet E$, then one 
defines
\startformula
A \triangle B := (A \cup B) \setminus (A \cap B).
\stopformula
Then the mapping $(A,B) \mapsto A \triangle B$ is a commutative, associative 
binary operator on the subsets of $E$.

Some people use instead $A \Delta B$, but this is not the traditional, nor the 
correct way, to write this « symmetric difference » of two sets. This is why, I 
guess, in TeX \triangle is an operator.
I have seen also \triangledown as an operator, but I don’t recall the context 
in which it was used…

Regarding the notation \nabla to denote the gradient, and \Delta, to denote the 
Laplace operator (which by the way can be defined as $\Delta u := \nabla \cdot 
(\nabla u)$), Mikael Sundqvist gave the correct observations.

Best regards: OK

Re: [NTG-context] Multiple bibliographies (bib-module, mkiv)

Hello Peng,
For a Bibliography with  separate sections you can use the following 
work-around:
Suppose you want a section primary sources, for which you have the bibfile, 
say, ps.bib, and a section secundary sources, for which have the bibfile 
ss.bib.
The first step is tro to make for each of them a .bbl-file with, what I would 
call, a  bbl-generator.tex:

\setupbibtex[database=ps.bib,sort=author]
%\setupbibtex[database=ss.bib,sort=author]

\setuppublications[alternative=apa] %or any other style

\starttext 

\stoptext 
++
This can be processed with mkii or mkiv. It generates a lot of auxiliary files, 
including an empty pdf, but the only important one is bbl-generator.bbl, 
which you rename to ps.bbl or ss.bbl according to which of the two bib-files 
you used.(= did not comment out)

The other files you need are two .tex-files with the complete set of 
\nocite[]'s of the two databases. Personally I never used \nocite{*}. If you 
use a Mac with BibDesk it is quite easy to make such a file. It gives you some 
extra flexibility.

You can then generate the sectioned bibliography with:
++
\input(Your setups, including those for your Bibliography setup)
\starttext 
\startchapter[bookmark=,label=,list=,marking=,reference=Bibliography,title={Bibliography}
\section{Primary sources}

\input ps.bbl
\input ps-nocite.tex
\placepublications[criterium=cite]

\section{Secundary sources}

\input ss.bbl
\input ss-nocite.tex
\placepublications[criterium=cite]

\stopchapter
\stoptext 
+++
That's all.

I hope it works for you.

Re: [NTG-context] Multiple bibliographies (bib-module, mkiv)

[Peng Zhang]

Hi Robert,

Thank you very much for this workaround! It does work. Would it be 
possible that I can make two fake/invisible sections? (without showing 
primary sources and secondary sources in your example)


I am doing my CV. I just want two separate reference lists, one for 
journal and one for published abstracts.


I am copying the CV template from wiki.

\definehead[CVHEAD][subject]

\setuphead[subject][style=\bfa,after={\blank[medium]}]


\definehead[SUBCVHEAD][subsubject]

\setuphead[subsubject][style=\bf,after={\blank[small]},before={\blank[small]}]


I want something like
\CVHEAD{References}
\SUBCVHEAD{Pulished Journal Articles}

list 1
\SUBCVHEAD{Pulished Abstracts}
list 2


Could I put two fake/invisible sections within those subcvhead?


Thanks,
Peng

[NTG-context] page reference to figure fails when figure location is none

[Sanjoy Mahajan]

Using a recent MkIV beta (2014.03.27), it seems that a page reference to
a figure fails if the figure location is none.  Here is a minimal
example:

  \starttext

  \input knuth

  \placefigure[none][regularref]{}{\pagereference[workaroundref]
  \externalfigure[cow.pdf]}

  \input knuth

  See \at{page}[workaroundref]  or \at{page}[regularref]

  \stoptext

The log file has

  references   unknown reference '[][regularref]'

and the .pdf file has

  See page 1 or page ??

That is, the \at{page}[regularref] doesn't work.  (But the workaround
reference does work.)

If the figure's location key is changed from none to nonumber or
just deleted, then the regularref page reference works.

It also works with MkII (with or without none), so I am guessing that
it is a bug in MkIV.

I have found a few other buglets with placefigure for which I will make

[NTG-context] mirrored leftmarginwidth in enumerations

[Sanjoy Mahajan]

If anyone has a suggestion for putting enumeration texts toward the
right edge of the left margin, I would be grateful.

In MkII enumerations, I would put a triangle (fig.2) in the left margin
using

\defineenumeration
  [pause]
  [title=no,
text={\externalfigure[fig.2][height=1em]},
location=inleft,
number=no,
  ]

The triangle was automatically aligned toward the right side of the left
margin (fill glue on the left), which was what I wanted, on even and odd
pages.

In MkIV, the marginal text is automatically aligned to the left side.
I restored the MkII effect using this hack (using a  instead of the
triangle, to make the example more self contained):

\defineenumeration
  [pause]
  [title=no,
   text={\hbox to \leftmarginwidth{\hfil $$}},
number=no,
alternative=inleft,
  ]

But I just realized that the hack doesn't work for double-sided layouts.

Using the leftmarginwidth is correct on the odd pages, but it is too big
for the even pages.  Thus, on page 2 of the example below, the 
overlaps the question text.

Is there a more idiomatic MkIV replacement for my hack?  Or is my hack
okay, but ConTeXt should be updated to interpret leftmarginwidth to mean
the leftmarginwidth, as appropriate for an odd or an even page?

Here is the example:

\setuplayout[marking=on,location=middle,
  backspace=1.25in,
  leftmargindistance=0.125in, leftmargin=0.625in,
  width=4.75in,
  rightmargindistance=0.25in, rightmargin=0.25in,
 ]

\setuppagenumbering[alternative={doublesided}]

\defineenumeration
  [pause]
  [title=no,
   text={\hbox to \leftmarginwidth{\hfil $$}},
number=no,
alternative=inleft,
  ]
  
\def\question#1{\startpause\relax #1 \stoppause}

\showframe

\question{hello}

Re: [NTG-context] lower superscripts in MkIV -- too low?

[Sanjoy Mahajan]

 we have a more modern implementation in the next beta

I tested the following with various flavors:

$
 x\mathstrut_{3} x_{3} 
 x^3 x\mathstrut^3 
 x^\circ x\mathstrut^\circ 
 20\mathstrut^\circ 20^\circ
$

Flavors that I tried: 

2014.03.27 MkIV
2014.02.14 MkIV
2013.06.07 MkII (from latest beta)
pdfTeX 1.40.14 (from Debian TL 2013)

(wrapping in \(start|stop)text or ending with \bye, as appropriate).

My observations:

The MkII and pdftex subscripts look too high.  I know that's
sacreligious, since it is what Knuth must have intended, and I am
surprised that I didn't notice it before.

The 2014.02.14 MkIV subscript with the strut looks too low, although the
x^3 with the strut looks reasonable, or is maybe just slightly too high.
The x^\circ looks fine.  The x\mathstrut^\circ is too high.  But the
20\mathstrut^\circ looks right (and looks too low without the strut).

In 2014.03.27 MkIV, the subscript- and subscript heights are unchanged
by the strut.  The subscript heights look right.  The superscript
heights all look okay, except for the 20\mathstrut^\circ, which is too
low (same height as without the strut).  In earlier versions, one could
raise the \circ using a \mathstrut, but that no longer has an effect.

The other change, and maybe I am hallucinating this one, is that the
horizontal spacing between the x and the 3 is now slightly different
with and without the strut: It is tighter with the strut.  I think it
looks better without the strut, but am not sure.

So, overall I think it has improved.  I also wonder:

1. about the right horizontal spacing (how tight it should be)

2. how to raise the \circ in 20^\circ

There are some issues:

- \starthanging doesn’t accept parameters (using \setuphanging for every second

- As you can see in wiki, the picture stands on the first line of the text. 
This is a MkII problem, it works with MkIV.

Re: [NTG-context] lower superscripts in MkIV -- too low?

[Otared Kavian]

Hi Sanjoy,

I agree with you to say that the position of subscripts and superscripts in 
mkiv is not perfect: the same remark applies to the position of the derivative 
sign « prime » as $u’(t)$.

Actually in mkii (and also in plain TeX) the positions of the superscripts in 
your example are the same, but this is not the case with subscripts:
$x_{3}\ x\mathstrut_{3}$
that is in mkii the latter $x\mathstrut_{3}$ gives a lower subscript, while in 
plain TeX both subscripts are positioned at an identical depth.

I would say the position of subscripts and superscripts in mkiv should be 
identical with one gets with the latest beta (version 2014.03.20 16:59) in the 
following example
\starttext
$x\mathstrut_{3}$ and $x\mathstrut^{3}$
\stoptext

However as Hans pointed out, regarding maths typesetting in mkiv there are also 
some font related issues.

Best regards: OK

I agree about \rm.  However, _{\tf blah} once (in MkII) selected the
text font.  e.g.

\starttext
\placeformula\startformula
M_{\tf Sun}
\stopformula
\stoptext

Is the II-IV change in \tf semantics intended?  It's not hard to adjust
for by using 'sed'.  I raise the issue only in case the change is not
intended.

Actually, the example just as above (i.e. using modern fonts) works fine
works in MkII and MkIV.  It also works if \setupbodyfont[palatino] is
inserted as the first line.

It's fails only when using Palatino with Euler (at least, in the way
that I did it).

That data doesn't say what the right behavior is.  But it may help you
decide.

[NTG-context] how to set the CropBox in MkIV?

[Sanjoy Mahajan]

What is the MkIV/LuaTeX way to set the CropBox?
In MkII/PDFTeX, I used

  \pdfpagesattr = {/CropBox [54 72 558 720]}

With MkIV, I've tried 

  \pdfcompresslevel 0
  \pdfbackendsetpagesattribute{CropBox}{[54 72 558 720]}
  \starttext
  \input knuth
  \stoptext

but that set the CropBox as a string, and didn't override the A4 setting:

  /Type/Pages /CropBox ([54 72 558 720])/Count 1/Kids[16 0 R]

I also tried

  \pdfcompresslevel 0
  \startluacode
  local box = lpdf.array{54, 72, 558, 720}
  lpdf.addtopagesattributes(CropBox,box)
  \stopluacode

  \starttext
  \input knuth
  \stoptext

and that produced an improved line in the Pages object:

  /Type/Pages /CropBox [ 54 72 558 720 ]/Count 1/Kids[16 0 R]

but the actual cropbox for the page is unchanged (A4), probably because
the page object itself (object #16) overrides the CropBox with this:

  /CropBox [ 0. 0. 595.2756 841.8898 ]

(This is all with the 2014.02.14 beta.)

Because of font loading, is this recommended way to use components
(rather than the old way of the \project line after \startcomponent)?
If so, I'll make a note on the wiki.


Yes. This is one of the changes from MkII to MkIV. I think that Hans had a 
This Way document on this.

[NTG-context] [Math in ConTeXt]

[Otared Kavian]

Hi all,

After a series of exchanges on the list, on the topic of how mathematics 
typesetting is and should be in ConTeXt, I am writing you this message to ask 
all those who use ConTeXt to typeset mathematics and who encounter various 
types of difficulties, or shortcomings, to send me their remarks, either on 
list or off list. 
I will check the problems with Aditya Mahajan and Mikael Sundqvist, and then 
submit feature requests or bug reports to Hans and Aditya who will try to fix 
the issues (I have asked these people about this, and they all agree…).

In order to help me manage efficiently the task, please add the following tag

 Hi Mikael,

 Basically, I see your problem with ConTeXts handling of math as a matter
 of taste!
 That is you want LaTeX syntax.

 It is easy enough to get the results you want.

 The only place where I see a bug is that a single prime is set larger than
 multple
 primes.

 regards
 Keith


Hi Keith,

I do not agree with you. It is not so important to have the same syntax as
in LaTeX (exception: it would be nice to get double bars from \| since it
does not make sense to have \| yield a single bar since | does), but to be
able to write very common formulas (look at the example with double
derivative with respect to x in my examples above, and tell me how to do
that correctly in ConTeXt!) in an acceptable way.

Best regards, Mikael

 Hi,

 I used ConTeXt (mkii) to write my PhD thesis in Mathematics in 2008. It
 worked just fine.

 At the moment I write some exams and hand-outs using ConTeXt, but
 research using LaTeX (since the journals do not really accept ConTeXt
 and my collaborators dont know ConTeXt).

 It certainly works OK to write math in ConTeXt, but I have a feeling
 that there are some things that are somewhat broken or not finetuned to
 output what mathematicians expect. Look at the attached pdf files [1]
 l.pdf (from LaTeX) and c.pdf (from latest standalone ConTeXt), with
 source l.tex and c.tex for some examples.


 In mkiv we follow some alternative approaches compared to mkii (and
 probably other tex macro packages) and some aspects indeed might need
 tuning (or more configuration options) .. I try hard to get away from
 hackery solutions (for several reasons).


 I agree it is good to avoid hackery as long as possible, and I for sure
 is ready to relearn how to write some things. With the examples I gave in
 the previous email in mind:

  * How am I supposed to write first derivative (f') and second derivative
 (f'') in such a way that they have the same type of prime (the prime in the
 first derivative is the one I prefer)?

 No sure if to call this a bug! It seems that a single prime is always
 larger than multiple ones!
 You can always change its size!


 I think the user should not have to change its size. All primes should
 have the same size, independent if they are one or several.



 * How am I supposed to write f_xx'' to get the output as in the LaTeX
 example (i.e. so that the primes are over the xx)?

 have to switch things around: f''_xx or f''_{xx}  depending on the actual
 result you want.


 I know about the grouping. Please have a look at my example files in my
 earlier post in this thread.




 * Could the default placement of limits in integrals be changed
 (integral=nolimits)? This is how it is done in almost all math books).

  Not sure what you want here! example? can be LateX


 As above, I gave examples...

 Best regards, Mikael



 * What about the size and finetuning of placement of indices in integrals
 and sums (and probably products, unions, ...)?
 * I remember I suggested that \| should be double bars in a previous
 thread on this list. Is there any drawback in giving double bars for \|? Of
 course I can relearn and use \lVert and \rVert, but I have a feeling that
 if we want people moving from LaTeX to ConTeXt, then this is the kind of
 things that should just work as expected...

Unless I am mistaken, Cambria is a font available for Windows. I'm using

Xits, I do not know.

Is it possible to put the uppercase = right  in math mode with Pagella ?

 that there are some things that are somewhat broken or not finetuned to
 output what mathematicians expect. Look at the attached pdf files [1]

 source l.tex and c.tex for some examples.


 In mkiv we follow some alternative approaches compared to mkii (and

 I agree it is good to avoid hackery as long as possible, and I for sure is

 (f'') in such a way that they have the same type of prime (the prime in the
 first derivative is the one I prefer)?

 No sure if to call this a bug! It seems that a single prime is always
 larger than multiple ones!
 You can always change its size!


I think the user should not have to change its size. All primes should have
the same size, independent if they are one or several.



 * How am I supposed to write f_xx'' to get the output as in the LaTeX
 example (i.e. so that the primes are over the xx)?

 have to switch things around: f''_xx or f''_{xx}  depending on the actual
 result you want.


I know about the grouping. Please have a look at my example files in my
earlier post in this thread.




 * Could the default placement of limits in integrals be changed
 (integral=nolimits)? This is how it is done in almost all math books).

 Not sure what you want here! example? can be LateX


As above, I gave examples...

 * What about the size and finetuning of placement of indices in integrals
 and sums (and probably products, unions, ...)?
 * I remember I suggested that \| should be double bars in a previous
 thread on this list. Is there any drawback in giving double bars for \|? Of
 course I can relearn and use \lVert and \rVert, but I have a feeling that
 if we want people moving from LaTeX to ConTeXt, then this is the kind of

Re: [NTG-context] OT: Reflections on usability ConTeXt for typesetting of mathematics

Hi,

I used ConTeXt (mkii) to write my PhD thesis in Mathematics in 2008. It
worked just fine.

At the moment I write some exams and hand-outs using ConTeXt, but research
using LaTeX (since the journals do not really accept ConTeXt and my
collaborators dont know ConTeXt).

It certainly works OK to write math in ConTeXt, but I have a feeling that
there are some things that are somewhat broken or not finetuned to output
what mathematicians expect. Look at the attached pdf files [1] l.pdf (from
LaTeX) and c.pdf (from latest standalone ConTeXt), with source l.tex and
c.tex for some examples.

When it comes to math environments, I think that thanks to the environments
in http://dl.contextgarden.net/myway/mathalign.pdf we are OK. I sometimes
miss the multline(d) environment from LaTeX.

Best regards, Mikael

[NTG-context] getting text outside cropmarks to work

Hello,

Under mkii we used to have a running footer that appeared below the crop
marks. Under mkiv I can't get that to work.

The MWE I'm trying (with ConTeXt mkiv from the TeXLive 2013 CD):

\def\TopText { Top Text }

\def\pagecutmarksymbol {\the\realpageno}

\let\pagecutmarkbottomtext \BottomText

\setuplayout[marking=text]

%\setuplayout[marking=on]

\starttext

\input knuth

\stoptext


Code like this used to work for us in mkii.


I tried it with both marking=text and marking=on, but in either case, I
get neither crop marks nor the text.
(In our real document, I was able to get crop marks with [marking=on].
But not text. And haven't figured out how to get crop marks in a MWE.)


Relevant guidance I've been trying to follow:
http://wiki.contextgarden.net/Imposition#Cut_marks
http://context.markmail.org/thread/kpayudrtabsti76i

Thanks for any help on how to get text (pagecutmarkbottomtext) to appear
outside the crop marks.

Re: [NTG-context] Change the default text colour for entire document

Hi,

In ConTeXt to change the default text colour for the entire document,
there are at least two settings that need to be configured:

  \setupcolors[textcolor=red]
  \setupinmargin[line=13,color=red,style=slanted,]

The border colour for tables remains black:

\setupcolors[textcolor=red]
\setupinmargin[color=red]

\starttext
{\bTABLE
\bTR \bTD One \eTD \bTD Two \eTD \eTR
\eTABLE}
\stoptext

How can you override *all* instances of black? (Ideally there would be
a single setting that is inherited by all.) That is, it is difficult
to know all the various aspects of a ConTeXt document that use the
default black colour -- margins, body text, table borders, and
possibly more that I don't know about.


Notes (local notes excluded because they use a different placement system)
and margin texts ignore the global text color because both mechanism reset
colors and many other settings to avoid unwanted output from local changes
in the main text etc.

Even though there is a comment about this problem for margin notes in
the source it wasn’t fixed yet but I think it makes sense to to so.


\appendtoks
\inheritmaintextcolor
\to \everybeforenoteinsert

\appendtoks
\inheritmaintextcolor
\to \everymargindatacontent

could work, but it needs testing as we cannot predict side effects


The problem with the black frames for natural tables are a result of the 
explicit
framecolor setup for it (I guess to avoid problems when you use metapost
backgrounds which use the framecolor value). A possible way to fix this is to
add a framecolor setup to \setupcolors which argument is now used as default
color for the frame of natural tables, this way can use this color also in other
commands (core functions as well as third party modules) to set a default value.


needs some thinking

\setupTABLE
  [framecolor=\maintextcolor]

some settings date from mkii times but again we need to think of side 
effects

Re: [NTG-context] Change the default text colour for entire document

[Keith J. Schultz]

Hi Everybody,

If I remember right colors can be defined in ConTeXt, right?

So why not just redefine black!

If this is stupid, the defaults get initialize before a redefined occurs!

forget it!

Just a stupid simplistic idea!

regards
Keith.

 Hi,
 
 In ConTeXt to change the default text colour for the entire document,
 there are at least two settings that need to be configured:
 
  \setupcolors[textcolor=red]
  \setupinmargin[line=13,color=red,style=slanted,]
 
 The border colour for tables remains black:
 
 \setupcolors[textcolor=red]
 \setupinmargin[color=red]
 
 \starttext
 {\bTABLE
 \bTR \bTD One \eTD \bTD Two \eTD \eTR
 \eTABLE}
 \stoptext
 
 How can you override *all* instances of black? (Ideally there would be
 a single setting that is inherited by all.) That is, it is difficult
 to know all the various aspects of a ConTeXt document that use the
 default black colour -- margins, body text, table borders, and
 possibly more that I don't know about.
 
 Notes (local notes excluded because they use a different placement system)
 and margin texts ignore the global text color because both mechanism reset
 colors and many other settings to avoid unwanted output from local changes
 in the main text etc.
 
 Even though there is a comment about this problem for margin notes in
 the source it wasn’t fixed yet but I think it makes sense to to so.
 
 \appendtoks
\inheritmaintextcolor
 \to \everybeforenoteinsert
 
 \appendtoks
\inheritmaintextcolor
 \to \everymargindatacontent
 
 could work, but it needs testing as we cannot predict side effects
 
 The problem with the black frames for natural tables are a result of the 
 explicit
 framecolor setup for it (I guess to avoid problems when you use metapost
 backgrounds which use the framecolor value). A possible way to fix this is to
 add a framecolor setup to \setupcolors which argument is now used as default
 color for the frame of natural tables, this way can use this color also in

[NTG-context] Misplaced \widehat and \widetilde in mkiv?

[Otared Kavian]

Hi Hans,

It seems that with the latest beta mkiv, version

ConTeXt  ver: 2014.01.23 01:55 MKIV beta  fmt: 2014.1.23  

\widetilde and \widehat in mathmode are misplaced (and this is so in any of the 
fonts I tried).
Please compare the result of the following in mkii (where everything is 
correct) and in mkiv:
 begin tilde-hat.tex
\starttext

We set ${\widetilde n}(t) := n(1 - t)$, and ${\widehat u}(\xi) := \int_{{\Bbb 
R}}\exp(-{\rm i}x\xi)f(x)dx$.

\stoptext
 end tilde-hat.tex
The attached PDF is obtained with mkiv.

Re: [NTG-context] unknown library 'loc'

Hi Hans,

Suppressing the message of a loc that is not needed would be the cleanest
method. 

IMHO, it should not be even causing a warning.

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 
  
argument ...fact that $2\times 5 = 10$. \dostopnormalblock 
  \dostartnormalblock {hint}...
\dodowithpar ...dler \v!construction \endcsname #1

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

you can add a file type-loc.mkiv someplace in your local tree with

this file can be used for local overrides (just some mkii compatible

Re: [NTG-context] ConTeXt hyphenation patterns for Indic languages

[Rajeesh K Nambiar]

 i uploaded a beta that has the patterns and language definitions .. but
 up
 to you to check it and provide better settings if needed


Thanks, Hans!
Now mkiv correctly loads the patterns and hyphenation works (though
even with \language[ml], log says language 'en' is active).

Is there a way to also enable mkii/texexec to load the patterns?
I did copy-paste the section from lang-def.mkiv to lang-ind.mkii and
also added an entry in lang-def.lua but the log does not show pattern
for ml loaded, in addition to mentioning language ml is undefined.


 Okay, is the best way to install beta to use the Standalone ConTeXt
 mechanism? Is it advisable to uninstall ConTeXt from TeXLive if so?
 (wiki says Context Standalone for Linux 32 bit is complied with
 glibc-2.3.6 while I have glibc-2.17).


 just install it in a different place and it will run independently from
 texlive

Installed on a separate location and works fine.

Indeed, but I am using mkii with XeTeX backend (texexec --xetex). I'm
trying to make Malayalam shaping work on mkiv (taking Devanagari
font-odv.lua as example) but it is quite complex, till then I'm
depending on mkii+xetex.

Re: [NTG-context] vertical square root upstroke (instead of having a slant)

With the following minimal file on MkIV (2013.05.28 00:36 MKIV current),
the upstroke of the square root is vertical instead of having the usual

I see this problem only with certain arrangements of variables (that
recur often in my book chapter on springs and piano strings).  For
example, it goes away after changing the \rho to a b.

\starttext
\startformula
\sqrt{Tb^2\over \rho}.
\stopformula
\stoptext

I know that the big math symbols are constructed differently in MkIV
and MkII.  Does the example above show an intended difference?


a radical has a couple of increasing sizes (discrete steps, if they have 
a slant depends of the font designer) before it switches to an 
extensible that then normally has no slant


(in context one can hook in a mp variant that keeps the slant)

(if needed we can make it an option to omit steps and always use upright)

\setuppublicationlist

maybeyear is one of the areas that need fixing. The simple on/off 
mechanism is not sufficient, because the behavior needs to be more complex:


1. If the citation style does not use the year as a key, do not append 
letters.


2. If the citation style uses year as key and only one publication/year 
of an author is quoted and listed (even if there are several in the bib 
file) do not append letter.


3. Append letter if citation style uses year AND more than one 
publication/year for given author is quoted and listed.


I assume that in order for this to work, Hans will have to rewrite the 
code which produces the .bbl file from the bib. Right now, AFAICS, the 
.bbl contains the entire .bib database. It should only contain the 
entries which are cited.


Alan, does that make sense to you?

Re: [NTG-context] Unexpected behaviour of enumeration in mkiv

 Hi,

 please have a look at the minimal example at the bottom.  I am
 typesetting theorems and lemmata which are numbered consecutively
 within chapters in a book.  I used the same code for a document
 written in mkii, and I thought I could just reuse it in mkiv.
 Obviously, there is something I am missing.  Question: How do I get
 the same output when compiling the following code with 'context' as
 when compiled with 'texexec'.

 When compiled with 'context', the chapter number is missing in the
 numbering of theorems. Lemmas are not numbered at all.

 ~~~snip~~~
 \setupenumerations
[title=yes,
style=normal,
list=all,
before={\blank[big]},
after={\blank[big]},
location=serried,

 Change “location=serried” to “alternative=serried”.

width=broad,
distance=0.5em,
headstyle=bold,
titlestyle=bold,
way=bychapter,
conversion=numbers]

 You have to change “conversion” to “numberconversion” but this isn’t
 necessary because numbers are the default conversion format.

 To have chapter numbers as part of the counter add “prefix=yes”.

 \defineenumeration
[theorem]
[text=Theorem, listtext={Theorem }]

 \defineenumeration
[lemma]
[text=Lemma, listtext={Lemma }, number=theorem]

 To use the counter of another enumeration use “counter=theorem”, not 
 “name=theorem”.

 Wolfgang


 Thanks Wolfgang for the quick answer.  I changed my code accordingly.
 The prefix=yes option, though, does not entirely do as I expect it.
 It adds the chapter+section number as a prefix to each theorem (and
 lemma).  As I have way=bychapter in my options, though, it doesn't
 reset after a new section started (which is what I want!). The effect
 is odd as you can see in the minimal example.

 I only want to have the chapter number as a prefix. It's probably
 simple? difficult?

 Minimal example:

 ~~~snip~~~
 \setupenumerations
 [title=yes,
 style=normal,
 list=all,
 before={\blank[big]},
 after={\blank[big]},
 alternative=serried,
 width=broad,
 distance=0.5em,
 headstyle=bold,
 titlestyle=bold,
 way=bychapter,
 prefix=yes]

 \defineenumeration
 [theorem]
 [text=Theorem, listtext={Theorem }]

 \defineenumeration
 [lemma]
 [text=Lemma, listtext={Lemma }, counter=theorem]

 \starttext

 \chapter{First chapter}

 \section{First section}

 \theorem Hello

 \theorem Hello

 \lemma Hello

 \theorem Hello

 \section{Second section}

 \lemma Hello

 \theorem Hello

 \chapter{Second chapter}

 \section{First section}

 \theorem Hello

 \lemma Hello

 \section{Second section}

 \lemma Hello

 \theorem Hello

 \stoptext
 ~~~snip~~~


To answer my own question, adding

way=bychapter,
prefixsegments=chapter,

did the job!

you can deduce that from \bibtexpublicationsparameter which you can read as

Akira Kakuto suggested me this:

Please add a line
#encoding: ASCII-8BIT
at the top of
/usr/local/texlive/2013/texmf-dist/scripts/context/ruby/base/switch.rb 

that fixed my problem, which is related to the texlive distro according to 
Hans, which is older than current

thanks to all!

 You have to change “conversion” to “numberconversion” but this isn’t

 To have chapter numbers as part of the counter add “prefix=yes”.

 To use the counter of another enumeration use “counter=theorem”, not

Thanks Wolfgang for the quick answer.  I changed my code accordingly.
The prefix=yes option, though, does not entirely do as I expect it.
It adds the chapter+section number as a prefix to each theorem (and
lemma).  As I have way=bychapter in my options, though, it doesn't
reset after a new section started (which is what I want!). The effect
is odd as you can see in the minimal example.

I only want to have the chapter number as a prefix. It's probably
simple? difficult?

[NTG-context] Integral limits

[Aditya Mahajan]

Hi,

In MkII, it was possible to change the limits on integrals using

   \setupmathematics[integral=...] % limits, nolimits, displaylimits

that would affect how \int, \iint, \iiint, \oint, etc behaved.

I can see two ways of definining a similar feature in MkIV.

1. Define \intop, \iintop, etc in char-def.lua and then somewhere define:

   \define\int{\intop\intlimits}
   \define\iint{\intop\intlimits}

  etc.

2. Define a new mathclass intop and use that in char-def.lua. Then, in 
the appropriate math-*.lua file, map intop to the appropriate macro.


What would be the best way to go?

Thanks,
Aditya

i prefer 2 (as these set the defaults) and we can make a definer for 
specific variants if needed (at all)


is intop the best name? (we don't need to be sparse)

I have to strongly disagree with you here. A critical edition is only a 
specialized case of parallel texts! You two or more editions that are 
contrasted/compared to each other.
Naturally, it must be bibliographically annotated and there are the comments of 
the author of the critical edition.

The  editions have to be typeset in parallel. There are many ways how an author 
can lay this out. In the far past it was common just to stack the contrasted 
versions on top of
each other! Very very ugly. Lots of examples in libraries. More recent ways are 
to use column. Yet, the more editions involved the harder it is to place on one 
page. For such cases
it would be best to spread them across two facing pages. 

The problem with the two page setup is synchronizing the comments, notes, 
discussion of the critical edition's author. For a half way pleasing layout 
these should interplaced between the contrasted editions across the two pages. 
Yes, not an easy task.

I agree that it is hard to automate the synchronization of text passages. The 
only viable approach would be at the paragraph level. A line level approach can 
only be achieved by
interaction of the author of the critical edition with synchronization marks of 
some sort inside the editions.

Early, in my education in Computer Linguistics, decades ago, we had project 
where we wrote a program for entry of critical editions. The editions/texts and 
comments were
entered in parallel on the tty-terminal screen and stored in a database. At 
that time we where no interested in fancy output and used a simple stacked 
output.

As you probably know yourself, it is the entry and synchronization of the 
editions that  is the problem an not as much the layout itself, though that is 
hard enough by itself.
I do not see any way to do this in a normal linear single pass process. The 
question is in how far ConTeXt can support this task. 
1) provide possibilities of laying out the texts synchronized in columns, 
stacks and two page layouts. Footnotes, under, columns, pages or across
either. Another, nice feature would be the availability of marginals in 
a synchronized way.
This should be a generalized module or set of commands as it 
can be used in many other fields be critical editions.
In other words a parallel texts layout package:
\defineparalleltextlayout[name][…]
\setupparalleltextlayout[name][…]{…}
\defineparalleltextpart[name][..]
\setupparalleltextpart[name][…]{…}
\startparalleltext[name][…]
\stopparalleltext
  . . .
 

2) providing commands that define which parts belong together
I would suggest that this be done mostly on the Lua side as you 
can then develop a database of sorts and worry about
the layout/typesetting of the critical edition later.
A package for marking up the editions directly.
\defineeditionslayout[name][…]
\setupeditionslayout[name][…]{…}
\defineedition[name][..]
\setupedition[name][…]{…}
\starteditionsl[name][…]
\stopeditions
\starteditiontext{name}{text}
\stopeditiontext
\startauthorremarks
\stopauthorsremarks
 . . .

desired MWE:
% definitions and setups
\starttext
   % some text
\starteditions[style1]
\starteditiontext{edition1}
   % some text

a lot depends on proper coding ... typesetting parallel texts is not per

also, if  1 page is used then we should not limit to 2 pages (or 
columns) in parallel

indeed. one cannot have the best of all worlds (perfect justification,

hard enough by itself.
I do not see any way to do this in a normal linear single pass process. The 
question is in how far ConTeXt can support this task.

 ...

time, motivation, etc ...


I have just a brain stormed possible starting point. It as you can see it has 
quite some felixiblity as to how the texts
is entered and ConTeXt does some rearranging during typesetting.

One type of critical edition we have not discussed is when the author whats to 
work on a word basis. But, that is even a bigger can
of worms for collating the data/texts.

Most of what I have describe it probably obvious to you, yet


well, keep collecting demands and examples ... best that we know what is 
needed (and by how many people, for how many years to come, as it makes 
no sense to develop code that is used once and then discarded because 
one moves to newer technologies) ...


we also need to keep in mind that this kind of things are author driven 
as publishers are not paying for this kind of things nor willing to 
invest / support development of tools (if they are interested in 
anything else than 25-50% profits at all).

[NTG-context] how to reduce \lineskiplimit in ConTeXt grid layout

[Lars Huttar]

As you know, in plain TeX, \lineskiplimit tunes the vertical glue
algorithm by specifying the minimum amount of space between the bottom
edge of one line and the top edge of the following line.

But in ConTeXt, it appears that \lineskiplimit is set to zero, at least
in grid mode.
We're using grid mode, and we have some occasional high ascenders, e.g.
capital letters with diacritics on top.
We have bodyfont size 8.1pt, and interlinespace = 9.3pt. We realize this
is less than the recommended ratio of 1.2.

Understandably, when those tall characters occur, we sometimes get a
blank line above them. It looks like the \lineskiplimit would be
violated if the 9.3pt interlinespace were enforced, so ConTeXt adds some
space (analogous to \lineskip in TeX?). But since we're on a grid, more
space has to be added in order to conform to the grid.

All that makes sense, but we would like to be able typeset the lines
closer together, and judge for ourselves whether it looks too bad. (When
we used to typeset the same text at 8.1pt/9.3pt using mkii, blank lines
did not occur.) Is there something similar to \lineskiplimit that we can
tweak? I've been reading section 5.5 Line Spacing in the context ref
manual, but I don't see anything there about changing a threshold
analogous to \lineskiplimit.

I tried setting \lineskiplimit=-2pt, but that caused a worse problem: a
blank line across both columns, instead of just one.

Thanks,
Lars

you can try to choose a more strict grid snapping method (see 
spac-ver.mkiv line 1375 etc ... some methods have tolerance, some snap 
always ..)

For certain values of pressing :-) Two pessimistic remarks about that: 
(1) I experimented with a mechanism that Hans build for mkii a while 
ago, and I found it difficult to decide how to define what was expected 
of parallel typesetting. In the end, I wasn't convinced that an entirely 
automated version was possible at all. (2) I'm afraid that's not part of 
the present project and is related neither to critical editions nor to

Looking forward to status reports! Will the improvements be
directly merged into Context or do you prefer releasing it as a
self-contained module?


During development, we need to keep the code separate since we need to 
document what we do for our funding agency, but it will be part of ConTeXt.

 When you say out of the box, I think you're referring to the
 gentium-tug package box, not the ConTeXt box... in other words, I should
 not expect Gentium to work just because I installed ConTeXt; I have to
 also install gentium-tug, right?
 The font is installed by default when installing the ConTeXt
 distribution. I thought it was also installed by default with the
 ConTeXt scheme in TeX Live, but apparently I was wrong. I can fix
 this. The scheme already contains a bunch of nice fonts and Gentium
 could/probably should be among them.


Just to confirm the above: After installing TeX Live context scheme on
Linux, Gentium was not in my names.tma. And when I tried to use
\setmainfont[Gentium], I got errors, 'simplefonts  font ''gentium'' not
found'. After installing the gentium-tug package (sudo
/usr/local/bin/tlmgr install gentium-tug), and compiling a .tex file
using \setmainfont[Gentium], the errors went away, and my names.tma now
includes several variants of Gentium. At no point did I run mtxrun
(knowingly).

On the other hand, on Windows, I had installed TeX Live context scheme
as well, and have not installed gentium-tug. But I did install Gentium
as an OS font (using TTF files). I then ran mtxrun --generate (as
suggested by Hans), and after that, gentium* showed up in names.tma, and
I was then able to successfully compile a .tex file using
\setmainfont[Gentium] with mkiv context. (But that didn't work before I
ran mtxrun --generate.)

Just a couple of data points in case they're relevant.

 Hi all,
 I'm following the instructions at
 http://wiki.contextgarden.net/Installing_a_TrueType_font,_step_by_step
 because I want to install a TTF (Gentium in fact) for ConTeXt to use.

Please note that:
- the top of the page says NOTE: The contents of this page are OLD /.../
- nobody in the ConTeXt community bothers about MKII (pdfTeX) any longer
- texfont.pl has always been a bit problematic and is definitely not
really maintained any longer
- you can find Gentium at http://www.ctan.org/pkg/gentium-tug (also in
TeX Live and in the ConTeXt distribution)
- Gentium works out-of-the-box in ConTeXt (see the documentation of gentium-tug)

 This is under TeX Live 2013, the context scheme, and I've been using
 ConTeXt mkiv.

So why bother about pdfTeX? The conversion is/was only ever needed
for MKII. In MKIV all fonts work out of the box. Other than what the
package provides, Wolfgang Schuster's new additions (is there any link
to point the users to?) make that even easier for users. It's probably
easiest to use the package now, but even if the package wasn't
provided, setting up the font in MKIV is relatively straightforward
without the need for any conversions of any kind.

 I can't find ttf2afm anywhere. Is it part of pdfTex? Do I have to have
 the pdftex scheme installed in order to install True-type fonts?

It's part of ttfutils, collection-fontutils. You cannot install an
additional scheme in TeX Live (or at least I think so, I'm not 100%
sure), but you can install an additional package or collection. But
really ... you don't need that program just for the sake of using
Gentium.

Hello,
I was looking into simplefonts
(http://wiki.contextgarden.net/simplefonts) and noticed the clause


if you’re running ConTeXt Standalone
http://wiki.contextgarden.net/ConTeXt_Standalone (which is a better
option)


Well I'm using TeXLive, but am happy to take good advice, so I looked at
http://wiki.contextgarden.net/ConTeXt_Standalone to see why it would be
a better option.
The basic reason I can see is that Standalone is updated more frequently.


Three or four years ago, when ConTeXt was moving from MkII to MkIV, 
you had to run through hoops to get context working with TL. Since the 
last two years, ConTeXt works out of the box in TL.



So if you're using bleeding-edge features of ConTeXt (including recent
fixes to simplefonts?), I can see wanting to use Standalone and have
access to the latest features and fixes.

On the other hand, if you're working on a large production project that
has to be careful of stability, is there any advantage to Standalone
over TeXLive? Sure, you can keep a standalone version frozen in place,
but then that seems equivalent to staying with an existing version of
TeXLive.


No. In some sense, it is better to use the frozen version that is part of 
TL rather than an arbitrary beta version from standalone. Every once in a 
while, the beta version has bugs (those are usually fixed in a matter of 
hours). But it can be tricky to decide which version to freeze for a long 
term production environment.


On the other hand, the version of ConTeXt that ships with TL is tested 
more thoroughly. So, there is some guarantee that it will not include any 
serious bugs.

Re: [NTG-context] Bug: Reloading Font

[Khaled Hosny]

 them.

 there's always xetex as alternative -)

Except I can’t use it :) even with MkII as there is zero support for
XeTeX’s (rudimentary) RTL model.

 (unless you're referring to wanting to use the microsoft word math
 renderer trickery -)

I never set math actually :) unless I’m testing a math font, but I can use
plain for that.

 One important aspect is that when using tex, one also wants
 flexibility and control and so a font system will have hooks and
 such. Using a mixed library / lua / tex approach would become pretty
 complex. Sure, the current lua code is not trivial either but can
 probably be simplified over time once settled down. One reason for
 me not to use xetex (plus its libs) is inflexibility. If we hadn't
 started luatex I might as well have opt out of tex altogether,
 especially because only with luatex i can do some of our projects
 within acceotable bounds (dev time, speed of machinery,
 flexibility).
 
 I don’t think much of LuaTeX’s flexibility (or XeTeX’s inflexibility) is
 related to the OpenType layout engine used.

I absolutely agree. All I wanted to know is whether ConTeXt can consider
integrating an optional different font machinery, so to not waste time
on something that will be of little use to me.

Re: [NTG-context] Bug: Reloading Font

[Hans Hagen]

 was a big system, but nowadays the tds tree is relatively small;
unless something magic happens, i think that at some point the
complexity of all these big things will explode (one can according
to the evangelists get a ruby on rails app up and running in minutes
... but try to update one a few years later) ... with respect to
tex: the source tree/build is not trivial (how many folks know all
ins-and-outs?) and it makes me already feel quite dependent .. it's
the instability of the whole eco system that bothers me

well, the formats don't evolve that much, at least not with respect
to what we need in tex ... most features are rather generic, but tex
user demands evolve and those will always influence matters; also,
in the (context) machinery at some point i want to play with other
approaches and then the only thing that matters is having data
available (we already have some par optimizing code in place for
instance)

(i'm more worried about inconsistencies and a mess in fonts than in
the opentype standard ... many characters / scripts / languages have
well properties, so in fact designers could do with predefined sets
of features and rules ... sort of the reverse of making shapes and
then the features: instead of for each font reinventing the wheel,
choose a set of logic, make shapes etc ... positioning is probably
most of the issue then; but that's another disucssion)


There are already few parts of OpenType that I’m not able to use in my
fonts for years because they break the fonts with LuaTeX horribly. I
understand the priorities of the team, that is why I think that
offloading font support is beneficial to everyone.


break in what sense? what features (just curious) ... anyway,


The mark filtering sets we discussed few years ago, for instance; I had
to redo the whole font in a much more complex way with few more
thousands of glyphs to avoid using them so the font remains usable with
ConTeXt, and I still get crashes every now and then that I stopped
bothering with reporting them.


Well, I can't fix something if I don't know about it ... one thing I 
learned the last years, is that one needs examples of usage (and I'm 
pretty sure that some of the implementation of an opentype engine is not 
a direct consequence if the standards but of usage).


Teaser: if another app doesn't crash, it doesn't mean that it does it 
right. But its behaviour could become the standard expected. I'm not 
saying that this is true in your case, but we need to keep this option 
open. Also, when something is non trivial (and I've had enough 
discussions to know that the spec is not always that clear) one might 
wonder about the spec in the first place ... trial and error (due to 
lack of fonts and examples) is part of opentype implementation 
development (ok, for much other dev too).


Which reminds me: on the agenda is to have a few more fields in glyph 
nodes so that we can simplify some of the code, but that's a something 
we will look into end-of-year when some other backend cleanup has 
happened.


I still remember a talk at bachotex where someone went through all 
version of indesign pointing out in which ones ligatures did / didn't 
work, workes differently. And look at opentype math ... some reverse 
engineering is needed. To me opentype is not a real standard but m ore 
reversed application specification where we have to look at what the 
inventors do and try to adapt to that.



there's always xetex as alternative -)


Except I can’t use it :) even with MkII as there is zero support for
XeTeX’s (rudimentary) RTL model.


(unless you're referring to wanting to use the microsoft word math
renderer trickery -)


I never set math actually :) unless I’m testing a math font, but I can use
plain for that.


One important aspect is that when using tex, one also wants
flexibility and control and so a font system will have hooks and
such. Using a mixed library / lua / tex approach would become pretty
complex. Sure, the current lua code is not trivial either but can
probably be simplified over time once settled down. One reason for
me not to use xetex (plus its libs) is inflexibility. If we hadn't
started luatex I might as well have opt out of tex altogether,
especially because only with luatex i can do some of our projects
within acceotable bounds (dev time, speed of machinery,
flexibility).


I don’t think much of LuaTeX’s flexibility (or XeTeX’s inflexibility) is
related to the OpenType layout engine used.

be taken into account when shaping, and also that shaping signals
things to be done later ... once we start thinking out of the box

Hi everyone,
I am trying to reproduce a novel I wrote with context years ago. This
time is spanish.
I use context only for books, not daily, so now I can't figure out how
to use fonts.
I have been going around and around for days avoiding to look for help
here for such a simple thing, but I surrendered. My last attempt was
using the simplefonts module.
Here is what I get (linux-64 ubuntu):

* texexec --pdf novel.tex*


you mix up old an new (mkii an dmkiv)

run this:

It works here with 2013.10.09 10:36 using MkIV and MkII. At least I

What's the error message you get for that minimal example? Are you
running MkII or MkIV?

 Without \coordinate it works. What fails?

If you remove \coordinate it should fail actually, since the
coordinate for (F) is unknown. Or did you mean you replaced (F) with
a coordinate like (0,2)?
