not solve my problem, since I wish to also use fractions with
script-size or scriptscript-size (\xfrac, \xxfrac). The specific
formula I have is
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +

With \fraction the minus sign is on the top of the fraction.

[NTG-context] Finding documentation for ConTeXt
Hi Everybody,
I am becoming more and more interested in ConTeXt.
I am gradually grasping the potential of ConTeXt and its
advantages over Lua(La)TeX.
My problem is finding decent documentation for ConTeXt.
Yes, there is ConTeXt Garden. But, let us be honest it is a big mess.
It mixes the old, the bad and the good.
I will admit the information there has improved greatly, and
YET finding the good and recent is not that easy.
Furthermore, since I am interested in what one can and can not
do in ConTeXt, I do not know ahead of time exactly what I am looking
for. Basically, I literally just stumble over what is good and interesting.
That would not be that bad if following the different links would not get
one lost and one can not your way back.
What would be needed are some decent top level entry points!
On Pragma there, also, are some very good documents, but if you
do not know where to look or what to look for, good searching!!
I know all you guys and gals working on ConTeXt are working hard,
but I hate to bother you with questions I want to do this or that, how do I
or where can I find a guide on manual for this and that. You have more
important things to do.
Wolfgang help me with finding a ConTeXt-Lua Programming guide by Hans.
sure its new, BUT could we put such guides into the Standalone distribution!
Even if they are incomplete!
What I could use is, now, is a ConTeXt programming guide!
Sorry, if I seem to harsh. I do understand how much work
documentation is.
regards
Keith.

Re: [NTG-context] Finding documentation for ConTeXt
I think that one of the problems is that ConTeXt can do almost anything, if you know how to ask it to do that. What I do is different what most people use it for, but it works (http://context.aanhet.net/svn/contextman/context-reference/en/co-pagedesign.pdf and http://www.lucet.fi/2013/01/metaposting/ and http://www.lucet.fi/2012/12/twpatterns/). There used to be a project to create a test suite with various types of files, but the links on the wiki refer to something from 2009 and that is, as you say, probably a be obsolete. I remember somebody talking about the test suite at one of the more recent ConTeXt meetings (2011/2012) - anyone with more info on that project? I think it'd help Keith (and many others, me included) to see what can be done. If you do not want to splurge in the books, the revised chapters on typography, fonts and pagedesign are recommended reading and pretty well up-to-date. They are linked to the main page of the garden, but these take you directly to the pdfs: http://context.aanhet.net/svn/contextman/context-reference/en/co-typography.pdf http://context.aanhet.net/svn/contextman/context-reference/en/co-fonts.pdf http://context.aanhet.net/svn/contextman/context-reference/en/co-pagedesign.pdf Other than that, it'd be helpful to know what you are looking for: are interested in typography, doing layouts for you and others? Is automated workflow what you are looking for? Dealing with maths? XML? What about dealing with colour? Interactivity? I guess I've resigned to the fact that ConTeXt is so huge that I'll never know more than a fraction of it - so I operate on a need-to-know basis. I learn something either because I'm certain it can be done or because I've seen it at a ConTeXt meeting or heard about it (a remark by Hans is to be blamed for my recent MetaPosting excursions). A slightly off-topic thought: there are hundreds of manuals on Microsoft Word. However, once you start going deeper into the program, it is not *that* easy to find a single good manual on the subject. With ConTeXt it is the other way round, finding 'for Dummies' information is hard, but once you want to dive deep, the developers are on this list to answer questions.

The \frac command uses \vcenter for the content while \dfrac and \tfrac only

Re: [NTG-context] Finding documentation for ConTeXt
Hi Mari, I thank you for you post. Basically, what I want to do is not in ConTeXt. So will have to develop it myself. One such need I have is the use of Nassi-Schneidermann Diagrams. I also, what to develop something along the line of literate programming. For that I will create Data structures on the Lua side and then visualize with ConTeXt in the form of UML, flowcharts, program specifications and documentation and the output of the actual programming code. Also, there are the things that ConTeXt and Lua(La)TeX do not offer or are not the way I like it. From your Link to the co-font.links.pdf I was able to look at the directory it was in. Interesting, is that its coresponding tex file is a half an year younger! What I do not understand why these documents are not in the standalone distribution. Sure I can search the web, but that has been cumbersome and very time consuming. The last point you mentioned that for the deep down things there is this list. You are right. But, comprehensive manuals are for me. And I want them on my computer. Furthermore I need to understand the ConTeXt (mkiv) programming language so I understand the *mkiv files. Programming is not new to me. regards Keith.

Re: [NTG-context] Math typesetting problems
Hi Janne,
Personnally I prefer to use the Plain TeX alternative \over (which works fine
in ConTeXt), that is
${a \over b}$
instead of
$\frac{a}{b}$
Compare the following two outputs in the example you want to typeset: I think
the second is more or less what you want
\starttext
Using \type{\frac} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +
U(t-s)) + \frac{(S(u-t) +
U(t-s))^2}{(u-s)}}{2(t-s)(u-t)}}}{\sqrt{2\pi\frac{(t-s)(u-t)}{u-s}}}
\stopformula
\blank
Using \type{\over} gives:
\startformula

Indeed it seems like the alignment is good with \dfrac, but this does
not solve my problem, since I wish to also use fractions with
script-size or scriptscript-size (\xfrac, \xxfrac). The specific
formula I have is
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +

With \dfrac it looks good.
With \fraction the minus sign is on the top of the fraction.

All the fraction macros of ConTeXt were based on \genfrac macro from AMSTeX so, in principle, they should behave in the same manner.

Then something has been lost in the MkII - MkIV transition. I am pretty sure (cannot check right now), that the code in MkII used \genfrac (which is a fancy wrapper around \over \ovewithdelim etc) Yes, MkII uses \genfrac but in MkIV the command is no longer available and all fraction commands have been rewritten.

Hi Janne,
Personnally I prefer to use the Plain TeX alternative \over (which works fine
in ConTeXt), that is
${a \over b}$
instead of
$\frac{a}{b}$
Compare the following two outputs in the example you want to typeset: I think
the second is more or less what you want
\starttext
Using \type{\frac} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +
U(t-s)) + \frac{(S(u-t) +
U(t-s))^2}{(u-s)}}{2(t-s)(u-t)}}}{\sqrt{2\pi\frac{(t-s)(u-t)}{u-s}}}
\stopformula
Formatting and temporary macros (I usually use \1 \2 etc) make a huge difference
in readability:
\startformula
\def\1
{\frac{
(u-s)x^2
- 2x(S(u-t)
+ U(t-s))
+ \frac{(S(u-t) + U(t-s))^2}
{(u-s)}
}{
2(t-s)(u-t)}
}
%
f_{B_t | B_s = S, B_u = U}(x) =
\frac { e^{\1} }
{ \sqrt{2\pi\frac{(t-s)(u-t)}{u-s}} }
\stopformula
\blank
Using \type{\over} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = {
e^{-{(u-s)x^2 - 2x(S(u-t) + U(t-s)) +
{(S(u-t) + U(t-s))^2 \over (u-s)} \over 2(t-s)(u-t)}} \over
\sqrt{2\pi {(t-s)(u-t) \over u-s}}}
\stopformula
\stoptext
At some stage, we also need to look at nath's automatic conversion of display
fractions to inline fractions (e.g., in the numberator \frac{ (S(u-t) +
U(t-s))^2 } { (u-s) } should be typeset as (S(u-t) + U(t-s))^2/(u-s) because it
is being typeset in \scriptstyle.

The use of \vcenter seems odd here as it means the fraction rule will no
longer guranteed to be centered around the math axis:
\starttext
\math{-\frac{a^{2^{2^2}}}{a} {a^{2^{2^2}}\over a}}
\stoptext
Also, why \frac is forcing text style fractions even in display mode?
\starttext
\startformula
-\frac{a^{2^{2^2}}}{a} {a^{2^{2^2}}\over a}
\stopformula
\stoptext
Both behaviours are different from MkII.

The wiki has a trick, but I think it stopped working at some stage -
maybe somebody can fix it (if it is broken):
http://wiki.contextgarden.net/Imposition#Getting_the_last_page_of_a_Booklet
(Obviously we aren't the only ones with this problem...)
I use the following code (luatex only).
\startusercode
function fillsignature(pages)

pages = pages - 2
local originalpages = pages

local neededpages = 0
local modulo = pages % 4
if modulo ~= 0 then
neededpages = 4 - modulo
end
if neededpages ~= 0 then
global.texio.write_nl('term and log', Here I added .. neededpages ..
pages)
tex.print(\\dorecurse{ .. neededpages .. }{\\page[empty]})
else
global.texio.write_nl('No page needed!')
