Re: Some questions about context

[Robin Kirkham]

Hi Wolfgang,

Many thanks for you help. I solved this problem by simply

\setuplayout[%
     ... ,
     leftedge=20mm,
     rightedge=20mm]
\setupheader[after=\hrule]

It seems that if you give only one argument to \setupheader, it  
applies to the whole header, including the left and right edges. So,  
I just extend the edges off the page (or anywhere I need -- I don't  
use the edges for anything else).

I'll use your \vrule idea to control the line thickness, although the  
\hrule default is about right anyway.

Thanks,

Robin

Hi Robin,

you can use \hrule height xx pt|cm|... to change the rulethickness. I
needed \vrule in my example because TeX was in horizontal mode where
you can only use \vrule, \hrule therefore can only be used in vertical
mode, you can see is depends on the current TeX if you can use \hrule
or \vrule.

Another thing is that your solution place the rule below the header
text, my method use the headerbackground and is therefore independant
from the current textstyle and size.

I played with your solution and found a few problem. I think there are
also problem that can appear with my solution but I had not tried to
find them.

\setuplayout
  [location=middle,
   leftedge=20mm,
   rightedge=20mm]

\setuppapersize[A5][A4]
%\showframe


\setupheader
  [after=\hrule]

\starttext

\input knuth

\page

\setupheader[state=empty]

\input knuth

\page

\setuppagenumbering[location=]
\setupheader[state=start]

\input knuth

\stoptext

Hi Robin,

I tried to make something working and came to the following three
methods to draw a rule under the header at the whole pagewidth.

If you use ConTeXts default layout with different margins you should
use bigger values for the rulewidth than only pagewidth.

\setuplayout[location=middle,cutspace=\backspace,width=middle]
%\setuppapersize[A5][A4]
%\showframe

\startuseMPgraphic{headerrule}
setbounds currentpicture to unitsquare xyscaled (\the\paperwidth,\the
\headerheight); draw (0,0)--(\the\paperwidth,0);
\stopuseMPgraphic

\defineoverlay
  [headerrule]
  [\useMPgraphic{headerrule}]

\defineoverlay
  [headerrule]
  [\vrule height\headerheight width0pt%
   \vrule width\paperwidth height 0.4pt\relax]

\defineoverlay
  [headerrule]
  [{\framed[width=\paperwidth,height=
\headerheight,frame=off,bottomframe=on]{}}]

\setupbackgrounds
  [header]
  [text]
  [background=headerrule]

\starttext

\input knuth

\stoptext

I didn't think of that ... however, suppressing the header on certain  
pages via e.g.

\setuphead[chapter][header=empty]

doesn't turn off the header background :-(

I have never used xypic. I looked at its page at 
http://www.tug.org/applications/Xy-pic/ and it says that it works with 
plain tex. Then it should also work with ConTeXt. Has anyone tried 
using it with ConTeXt?

A better way is to use \setupbackgrounds. You can specify the exact 
region of the page that you want, and it accepts all the parameters of 
framed, so you can change the rule thickness, background, etc. And for 
a really fancy layout, you can use a metapost background.

\defineenumeration[theorem][headstyle=normal|bold|italic|(any font 
commnad)]

No simple way right now. It is possible to do that using left and 
right keys. So, something like

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

If you do not want the dot after the number, say stopper=, above.

In ConTeXt this is much easier.

\defineenumeration[theorem][conversion=myconversion]

so, you can do something like

\def\withpagenumbercommand#1{\numbers{#1}.blah\currentpage}

\defineconversion [withpagenumber] [\withpagenumbercommand]

\defineenumeration[test][conversion=withpagenumber]

(I tested this, and this is not working. In fact conversion is not 
working with enumerations). This will be fixed soon. If you need it 
immediately, there is just a one line change as a workaround.

Hi all,

Moreover, how do you get a rule in the header that extends from the  
left of the left margin, right across to the right of the right

For your headers try this:

---

\setupheader
	[text]
	[after=\hrule]

\starttext
\input tufte
\stoptext

---

You can change the actual content of your headers via  
\setupheadertexts ...

Instead of the \hrule command above you could also resort to  
\thinrule. The global behaviour of \thinrule can then be customized  
via \setupthinrules ... However, this comes at the cost of  
introducing additional vertical space between your header text and  
the rule. On the contrary \hrule sticks to the text. Choose whatever  
suits you best.

(To the experts: is this \thinrule behaviour intended?)

Best wishes,
Oliver

Thank you very much for give me this opportunity.
Enumerations work but I need more customization:

1) How can you change the style of the text (Theorem in our example)?
2) How can you change the position of the counter: "1 Theorem" rather
than "Theorem 1"
3) Is it possible to change the counter? In LaTeX, with much effort and
help, I could write some code for displaying something like:

Theorem [number of theorem].[numberofpageitappears]. ....

If you want to see the code, I could give you

4) What about the indentation of the "body" of the theorem?. If you put:

\starttheorem
This is an important theorem skjdskad sda sdas dsad asdas das dsafs f
dsfsdfsdf dfsdf sdf dsfsd fsdfsd fds fdsf ds fsd fds fsdfsdfs fdsfsd f
\stoptheorem

the text is indented a little bit after the begginning of the line. We
could have a normal indentation (like AMS theorem do)?

5) Is there an equivalent to \newenvironment in latex? I think about the
demostration:

\newenvironment{demo}{\medskip Demostració.}{\hfill $\Box$}



I'm sure all of that is possible to do with context....


And another question (in other topic): how we can do lines at header and
footer like fancyheaders in latex?

enumerations. This is what I ususally do

\defineenumeration[theorem][style=italic,text=Theorem,location=hanging]

\starttheorem
This is an important theorem
\stoptheorem

They do almost everything on what is needed for theorems. I am working 
on providing missing features, so if you find something is missing, 
feel free to ask.

Another question: how get the equivalent of ams theorem package?
Sorry for no ask this before and another time, thanks

Xan.

Re: Some questions about context

[Xan]

Well, thank you very much to all of you: Wolfgang, Aditya and Mojca.

First of all thank you for answering to what I want (in latex groups 
people use to answer "this can't be done" or "do you really want that?")

And secondly, wow!! you provided very amount of information: examples 
and code. Good!!! More than ever I imagine

I will study all of that

Thanks,
Xan.

PS: Yes, I refer to xyfig. And my version is
texexec --version

What do you mean by "not supported any more". ConTeXt defaults to pdf, but 
texexec --dvi --nobackends will give you a dvi file.

and allows source specials for forward and backward search. Occasionally, 
that is really handy.

Also note that dvi mode is not really supported any more. How old is
your ConTeXt/TeX distribution? (texexec --version or ctxtools
--contextversion)
New versions should give you pdf output by default.

Yes, dvi is indeed faster, but ...

I do not use dvi route, but the page should be rotated in the ps file. 
AFAIU, dvi has no option for specifying the page size or page 
orientation. The viewers that honor ps code for page orientation and 
size rely on the manner that latex puts in those commands in the dvi 
file. I do not know if ConTeXt follows that route or not.

A lot of Latex packages are built into ConTeXt. See

There are also numbers, which I find easier to use. See 
http://wiki.contextgarden.net/Counters

I would suggest always use \usemodule[newmat] in your documents. For 
inline math, ConTeXt can do everything that LaTeX (and amsmath) do. 
For multi-line display, I would consider nath and amsl obsolete. 
Almost all of the functionality is available in the core. I wrote an 
article in Maps last year showing how to do the common multiline 
displays using ConTeXt. I do not think that article is available 
online to non-members of ntg right now.

The matharrows My Way is a slightly out of date. For matharrows, 
documentation is also provided in math-ext.tex.

And a to be written My Way on subformula numbering.

You do need to correct the spelling ;) \alpha. Also see
http://wiki.contextgarden.net/Math/basic

I am working on explaining the whole math thing at 
http://wiki.contextgarden.net/Math_new but progress has been slow.

Also read the documentation for \defineframedtext, and text 
backgrounds (which can also split across pages).

Also \enableregime[utf] for utf input encoding (same as 
\usepackage[utf-8]{inputenc}).

ConTeXt use PDF as default output format. A short test with the dvips
way show a rotated content but the page is not roatated, this seems to
be not suported

The ConTeXt method for headers is:

\setupheadertexts[centered on odd and even page]
\setupheadertexts[left on odd and even page][right on odd and even page]
\setupheadertexts[left on even page][right on even page]
                 [left on odd page][right on odd page]

The same methos id used for footer with \setupfootertexts instead of
\setupheadertexts.

I attached a file that provides another way to set the headers and
footers in your document. You can use it with the command 
\usemodule[wolf-txt]. A few examples can be found in the source.

\setupfootertexts[\pagenumber/\lastpage]

You can use the plain TeX command \newcount\mycount or the ConTeXt
command \newcounter\mycount to create a counter. The ConTeXt methos
provides also the two commands \increment\mycount to increase your own
counter by one and the command \decrement\mycount to reduce your own
counter by one.

ConTeXt provides now many functions from these modules by default.
Aditya wrote a few articles about the new option for maths in his My
Ways and at the wiki.

Please take a look at the following articles

http://dl.contextgarden.net/myway/mathalign.pdf

Do you mean xypic?

Take a look at Tikz/Pgf:

http://sourceforge.net/projects/pgf/

or MetaPost/MetaFun:

http://wiki.contextgarden.net/MetaPost
http://wiki.contextgarden.net/MetaFun

bot come with their own manuals.

This should work by default. AFAIK the AMS symbols are enabled by
default in ConTeXT. A short test worked without problems.

> 8) How can we do a "minipage" in context?

You can use the more powerful frame environemnt.

\starttext

\framed[width=6cm,align=right]{\readfile{knuth}\donothing\donothing}

\stoptext

You set the language for your document with the \mainlanguage[xx] and
the \language[xx] commands where "xx" stands for your language id as
"en" for english.

Some questions about context

[Xan]

Hi,

I'm new user of context. I gone from latex, which I use in the last 5 
years intensively

I read your wiki but I don't find some answers to my wishes. Basically I 
want to know what are the equivalent of latex commands/packages in 
context. Can you help me in thay?. Thanks in advance.... so let's go:

1) The first question is about landscape mode and xdvi. In latex, if we 
want landscape, we put:

\documentclass[a4paper,10ptt,landscape]{article}

but when we see .dvi in xdvi, xdvi does not detects automatically that 
it's in landscape mode.

For that, we have to put:

\usepackage[dvips,...]{geometry}

now the xdvi show .dvi in landscape mode


The question is, how we get the same in context?. If we put:

\setuppapersize[A4,landscape][A4,landscape]

the xdvi program does not detect that .dvi is in landscape mode. Is 
there an equivalent command of geometry that allow that?

2) In latex there is the fancyhdr package that allows to put lines at 
bottom and at top of the page and put right and left headings and 
footers like: \rhead{Hello} ....

What is the equivalent in context?

3) Is there an equivalent to the package lastpage in context? So can we 
put [number of page]/[total number of pages] at the bottom of the page?

4) How can we create new counters in context? Like latex 
\newcounter{mycount}

5) In mathematics, in context there are three modules: "nath", "amsl", 
"new math", according to http://wiki.contextgarden.net/Math

What are these features and limitations? What is the "best"?

6) Is there an equivalent module of xyfig?

7) Is there an equivalence of amssymbols?. How can I display for example 
$x \leadsto \int_a^b \arcsin (x+\cos \alhpa)$?

8) How can we do a "minipage" in context?

9) Can you tell me some link about babel and hipernation?


Thank you very much,
Xan.
