A figure id like in 1.2 can have kerning between the 1 and dot,
and the dot and 2. But when it is coded as 1{.}2, it won't.
still messed up: math display formulas, strange number reversion and
swapping l/r [since omega has bugs with math i'm not sure what is the
reason]
maybe duncan/idris/taco have an idea
It looks like the displays in aleph are a bit broken if you mix RL text
with LR math. I'll have a closer look.

Hi,
When I use palatino and euler, I do not get calligraphic font. How
can I define a typescript to use the calligraphic font from lm.
This is my setup
\definetypeface [pal] [rm] [serif] [palatino]
[default] [encoding=texnansi]
\definetypeface [pal] [tt] [mono] [modern]

\setupbodyfont[pal,10pt]
\starttext
${\cal A}A {\cal B}B$

I still do not know what is why calligraphic letters do not come out
correctly with euler, but the following definition works
\usetypescript[palatino] [ec]
\definetypeface [palatino] [mm] [math] [euler] [euler] [rscale=1.03]
\setupbodyfont[palatino,11pt]
\def\mathcal#1{\text{\definedfont[cmsy10]#1\/}}
and then I can use \mathcal{A} etc.
The caligraphic letters for Euler are defined in eusm (Euler Script).
For some reason this is not loaded in context. The following works
\definefontsynonym [EulerScript] [eusm10]
\def\mathcal#1{\text{\definedfont[EulerScript]#1\/}}
Why is eusm not used with \cal? Context uses zeusm10 as the sy font
and zeusm should contain eusm (atleast this is what I understand from
ftp://tug.ctan.org/pub/tex-archive/fonts/eulervm/source/latex/eulervm/fontinst/fontevm.tex)
What is missing from math-eul.tex?

and the page number aligned with the *outer* edge of the margin and a
1-pt rule below the entire header (from below the chapter number to
below the page number). How would one do this elegantly (or even
inelegantly)?
First forget about the wrong pagenumber positioning. Here's the most

But I don't know if there's a simple extention to it to draw the
missing line inbetween.
Here's another solution, which is the wrong way of doing things (it's
way too slow and meant for more complex things than a simple rule, but
could be optimezed if useMPgraphic was replaced with reusable or
unique). Also try \showlayout and see meta-pag.tex in the ConTeXt

\startuseMPgraphic{PageFrame}
StartPage ;

if OnRightPage :
x2 = BackSpace+TextWidth = x1 + LeftMarginDistance +
LeftMarginWidth + TextWidth;
else:
x2 = BackSpace = x1 - (RightMarginDistance + RightMarginWidth + TextWidth);

StopPage;
\stopuseMPgraphic
\defineoverlay
[PageFrame][\useMPgraphic{PageFrame}]
\setupbackgrounds
[page]
[background=PageFrame]
The trird solutions is probably the way to go, but it influences only
a single page and \getmarking[chapter] has no influence. I guess that
a minor modification is needed to handle both left right page

one:
\definelayer

[NTG-context] continuous numbering of subsection
Dear ConTeXt Experts I am still sometimes confused about how to set up simple things... I want to have a subsection level head type (topic) with a numbering that runs undependently from the section numbering, like so: 1. First Topic ... I. Section One ... 2. Second Topic ... 3. Third Topic ... 4. Fourth Topic ... II. Section Two 5. Fifth Topic ... 6. Sixth Topic ... III. Section Three ... And so on. ConTeXtgarden, the manual, etc. show in great detail how to set up the /appearence/ of head parts (incl. numbercommand), but I cannot find an explanation of the handling of the LaTeX equivalent to counters (their definition, incrementing, resetting, etc.). The explanation of \setupheadnumber in the manual (p. 172) is quite obscure to me -- how do I specify that I do not want higher levels of head to reset my numbering? Thank you!

If we get rid of those exceptions the separator problem will go away. But then math will be messed up. The problem is that the + - . are ambiguous; sometimes they have a mathematical significance; sometimes a separator significance. We need the exception for math (generally done the usual l-r way) but don't need it for separators (done in the r-l way). isn't it simplier then to disable otp's in math mode What I could do is define two filter sequences: UTFArabic and UTFArabicMath.

Taco, Hans, let me know what you think before I work on this. It is really inefficient to have to define an entire ot stack just to change one otp.

On the other hand, I am a very visual thinker, and I don't remember commands well, so even ConTexT (which seems a lot simpler than LaTeX) is a big stretch for me. We will see... it's a stepwise process - first set up a basic page style (next time in a big bookshop i'll take a look at the series) and set up a font; that way you get an idea how well things will fit - then develop the structure + associated style mapping while writing (or converting) ask yourself: - do i need to render this differently - do i get the feeling that i enter too much code if so, then add structure This is how context itself evolved (after all, it was written in an educational context where structure, reuse etc is important). Just don't try to make up the style at the beginning, polishing it every now and then is a nice distraction. Also, using metapost for the graphics is fun in itself (and may save you lots of time).

Hi Hans Hagen schrieb: \setuphead [chapter][resetnumber=no] \setupsection[section][previousnumber=no] Ok, I undestand. I apologise that my example was too short. I'd like to have things more flexible: If an arbitrary and irregular number of levels is introduced (sections, subsections, etc., numbered hierarchically as usual), the topic numbering should remain continuous and unaffected (that's why I thought, a separate definition, as in \definehead[topic][...], would be appropriate). Conceptually, though, topic is a section-like subdivision, so, for example, should appear in the TOC. This is typical e.g. in (German) law texts (here with § as a topic marker but this is not the point), Example: I. ... Chapter § 1 ... 1 ... Section § 2 ... Topic in section 1.1 ... Subsection § 3 ... Topic in subsection § 4 ... 1.2 ... § 5 ... 2 ... § 6 ... § 7 ... 2.1 ... § 8 ... II. ... § 9 ... Topic in chapter 1 ... § 10 ... § 11 ... 1.1 ... § 12 ... Of course, referencing, entry in TOC, index etc. should be correct. It would be even more preferable if one could attach the topic numbering to a specified level, say, chapters. The above example then would become: I. ... Chapter § 1 ... Topic in chapter 1 ... Section § 2 ... Topic in section 1.1 ... Subsection § 3 ... Topic in subsection § 4 ... 1.2 ... § 5 ... 2 ... § 6 ... § 7 ... 2.1 ... § 8 ... II. ... § 1 ... First topic in second chapter 1 ... § 2 § 3 1.1 ... § 4 ...

[NTG-context] Clipping again
Hi, I confess I got some earlier advice on this issue, but I've never been able to apply it to find a resolution. In the buffer that follows, I define a clipping box: % clipping path path cpath; cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle; cpath:=cpath scaled 1u; A function is created and scaled: % scale and draw graph P:=P scaled u; draw P withcolor blue; The picture is clipped and saved: % clip and save current picture picture pic; clip currentpicture to cpath; pic:=currentpicture; Then it is redrawn later. % redraw line draw pic; Unfortunately, even though this works, mathematicians really want arrows at each end of the graph. Easy enough to do with drawdblarrow P withcolor blue, but the arrows then get clipped. What I really need is to adapt the code below so that my function is clipped to the boundary box, but then redrawn with arrows at each end of it. If anyone can adjust my code to do that, it would be much appreciated, and it would break down a barrier I've faced for years with metapost coding. Note that I've tried some stuff with cutbefore and cutafter with some success.

Re: [NTG-context] arab (omega)
Dear gang,
I have redone this. Now there are two filter sequences, one for main text
and one for using the arabic-font digits in math mode.
http://wiki.contextgarden.net/Aleph_Guide#Installing
has been updated, get the new uni2cuni.zip. I'll update m-gamma soon so
this will be part of the distro if Hans accepts-)
Here is a test file that works here. Note (see the sqrt example) that
omarb apparently does not have U+066B, the Arabic decimal point. And the
Arabic comma maps to the lm comma in math mode (since omarb maps the
arabic comma to U+002C in the omarb virtual
font-sigh). So there is further work needed to get this all just right,
including recompiling the fonts etc...

It is my understanding that the contents of $$ is unaffected by
OTPs (and if it is not, it should be made so. Math is a language
on its own).
ok, it's done. The new ocp is here:
http://wiki.contextgarden.net/images/2/27/Uni2cuni.zip
and the instructions are here:
http://wiki.contextgarden.net/Aleph_Guide#Installing
Now, in normal text, +, -, and . are treated as separators, not plus
sign,
minus, and decimal point. If you want math use $$ etc. but then you will
get the math font not omarb (which is standard practice in the
Arabic-script world).
I have no idea if this affects Hans' solution (have not upgraded yet);
this is all experimental so things may change.
An aside: Classical Arabic is more sensical. Consider the number 3721. In
classical Arabic one says, one and twenty and and seven hundred and
three
thousand, which makes much more sense for a r-l language. So one would
write the numeral from r to l and it would look the same. How decimals
would be handled in the classical case needs a bit of research

Re: [NTG-context] Clipping again
Mojca, Good question of course. However, I am using this for intermediate algebra students so the graphs will be lines, absolute value, quadratics, polynomials, rational functions, radical functions, exponential and logarithmic functions. In each case, I would adjust the window to see all important behavior of the function, extrema, etc. So, for example, if I needed to draw y=12-x^2, I would not clip this to the boundary (-10,-10)--(10,-10)-- (10,10)--(-10,10)--cycle, because that would chop off the top of the parabola, and if I added arrows, it would look like I had two branches. Rather, I might clip y=12-x^2 to the boundary (-10,-20)-- (10,-20)--(10,20)--(-10,20)--cycle in order to see the turning point of the parabola. That is, I would choose a boundary that would present arrow heads at each end of the curve. In the case of rational functions, I would clip each branch separately. I hope this answers the question.

Just a guess: since you used the --alone switch, is there a path to the current directory from which you invoked texexec --make --alone Without the --alone switch the fmt file should go into \texmf-linux\web2c or \texmf-linux\web2c\pdfetex, depending on your texexec.ini setup. IIRC, the new (ruby) texexec does not read texexec.ini. One possibility is that $TEXMFLOCAL is not set (as you did not run setuptex) so texexec did not know where to place the format files. This also happens with Miktex and texexec creates a directory pdfetex in the current directory and dumps the format files there. You can try moving the fmt files to /usr/loca/cont/tex/texmf-local/web2c/pdfetex Aditya ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
