I have been using ConTeXt for a short time now, after I switched from
LaTeX. I find it quite great, but I have two queries regarding it. I
am using teTeX in Debian (unstable).
1. Are the Lucida Bright fonts used in the documentation part of the
complete teTeX documentation or are they fonts which need to be
obtained separately? I have read a thread about this on the archive
of this list, and tried all possible combinations suggested there
in vain.
2. The tutorial tells us to refer to other sources (The TeX Book) for
more on Math typesetting. Is there any online resource which would
explain TeX (as opposed to LaTeX) math?
Thanks.
Kumar

most math (also in latex) is tex math, macro packages add additional
symbols (context has them), some matrix stuff (is available in math
modules) and font handling (depends on font system used)
the best resource is still "the tex book"

Most math in latex is *not* same as tex math. Though, most that can be
done with latex can also be done in tex, but latex does provide a nice
interface which sadly is missing in context. amsl and nath modules provide
some of this functionality but a lot still needs to be done to make
Context math handling as easy as it is in Latex.
Having said that, the most commonly used math functionality of
latex+amsmath is available in context. Unfortunately it is not well
documented. You need to read some latex amsmath tutorial to get familiar
with the syntax, then you can simply replace \begin{...} \end{...} pairs
with \start .... \stop pairs and the basic features will work.

What is the development status of amsl and nath modules?

Do you mean that everything between $ $ and \begin{math} \end{math} is
different?
a + b
\int ...
\sqrt
etc is not different is it?

No, I mean the complicated math is much harder in context. Consider
\begin{align}
a &= b \\
c &= d \notag \\
&= f \notag \\
&= g
\end{align}
which will typeset as
a = b (1)
c = d
= f
= g (2)
There is no Context way to do it, and one has to resort to plain tex
\placeformula
$$
\eqalignno{
a &= b &\formulanumber \cr
c &= d \cr
&= f \cr
&= g \formulanumber}
$$
Context gives the same result, but the input syntax is much more verbose
than the latex syntax.
Latex also has a lot of other useful enviromnemts like
\begin{equation}
\begin{split}
a &= b \\
&= c
\end{split}
\end{equation}
Again, the same effect can be achieved in plain tex, but it is more
verbose.
amsmath also has some useful environments like multalign and aligned,
gathered, faligned, alignat, etc. Some of their functionality can be
achieved using \start stop array from amsl but the amsmath environments
have a lot more features.
There are certain features that are much more difficult to achieve using
context. Consider equation subnumbering. In latex, it is as simple as
\begin{subequations}
\begin{align}
a &= b \\
c &= d
\end{align}
\end{subequations}
Compare this from how to do this in context (see the wiki). You have to
*manually* set the number of the subequation. Actually, for equation
numbering and refering, the context way is rather limited. Consider
something like an align environment
a &= b\\
c &= d\\
e &= f
Suppose, I want to refer to the second equation. In latex, I can simply
add \label{eq:2} and the end of c&= d and then \ref{eq:2}. For context,
the reference label goes at the top, with \placeformula[eqs]. But I am not
sure, how to give individual labels to each equations.
Browse through http://www-sop.inria.fr/miaou/latex/voss-math.pdf which
explains almost all math tricks in latex. For some of the more complicated
stuff, compare the latex code and the context code to achieve that result.
Context has all the features, but for complicated maths, they are low
level tricks. There is no upper layer like amsmath making life easier for
the user. It will be nice to have such a layer.

this 'loose label' is one of the ugliest concept i can think of -)
i'm willing to implement anything reasonable but since i hardly use
such math i only act on 'i want to achieve this' kind of specs (i have
no time to read tons of tex documents)
much if this 'complicated' math is not that complicated to support,see
attached file
btw, defaulting to numbers and then using \notag is messy; i prefer
readable code, even if it takes more bytes; inventing a formula takes
more time than keying it in. Also, more structure, means more hooks
for configurability

If you come up with any other way, I will be glad to use it. Frankly,
I do not think that the latex syntax is the best, but plain tex looks
too indimidating and context does not have anything yet.

Fine by me. Your method is perfectly acceptable.

Wonderful. I did not know that something like this can be done so
easily in context.

> read tons of tex documents)
Here are features that I would want context math to have. I do not
care about the input syntax (whether it is same as latex or not) as
long as the features are there.
1. Have align support with variable number of columns.
a &= b
&= c &+ d
& &+ e
should be typeset as
a = b
= c + d
+ e
2. Have a mechanism to individually number/not-number an equation.
3. Have a gather environment. Depending on the user option should
either center, left justify or right justify all equations. Useful
when you have a bunch of equation together and do not want to have
startforumla and stopformula after each of them.
4. In align you should be able to specify the separation between
columns. There should be some input syntax that allows you to typeset
an output like
a = b c = d
e = f g = h
It will be great if you can number each equation (i.e. four number in
the above example). There should be an option to only number each
line.
5. have a splitformula environment that allows
a =& b
& + c \\
& + d
to come out as
a = b
+ c
+ e (1)
with only one formula number. The formula number should be at the last
line or the center of the whole formula, configurable by an option.
6. Allow, someway of typesetting
a = b + c
Using some result
= d + e
that is, you should be able to come out of the align mode temporarily
and then go back. Latex calls this intertext. Have some means to
adjust the before and after skips of intertext. Something like
\setupintertextskip[small or medium or big]
7. Allow some way of typesetting multilined formula where
first line is left aligned
second line after some hskip
third line after some hskip
...
last line right alinged
This should have only one formula number, either on the last line or
in the center of the display.
8. Have a version of align, gather and multiline that can be used
inside a formula. So one should be able to type
\startformula
\left.\startaligned
\NC a \NC= b \NR
\NC c \NC= d \NR
\stopaligned\right\}
\implies
\startaligned
\NC b \NC= a \NR
\NC d \NC= c \NR
\stopaligned
\stopformula
to get
a = b } => b = a
c = d } d = c
where the implies is centered between the two lined.
Have an option to make these environments come at the top, middle or
bottom of the baseline.
9. Allow easy input of multiline subscripts. Suppose I want
\sum
a < b
c < d
e < f
10. Allow the big subscripts of math operators to be smashed to the
left or right. Suppse, I have
a \times \lim_{a very long equation} b_n
There should be a command, say \smashoperator such that
a \times \smashoperator\lim_{a very long equation} b_n
comes as
a lim b_n
a very long eq
where (a very long equation) in centered beneath the center of lim but
the "bounding box" is the bb of lim not the bb of the subscript
Also
a \times \smashoperator[r]\lim_{a very long equation} b_n
should come as
a lim b_n
a very lone eq
where the "bounding box" of a lim on the right is the bb of the lim,
on the left is the bb of the subscript.
Similarly of \smashoperator[l]
11. Have commands like \medop and \bigop which typeset the following
operator slightly smaller or slightly larger.
12. Have a command say \novheight (or whatever) so that while typing
\left\{\novheight \sum_{i=0}^n a_n \right\}
the braces do not take the size of the sum into account while scaling.
13. Have a command say \tag so that
\startformula
a = b \tag{*}
\stopformula
comes out as
a = b (*)
14. Allow a framed command that works with align and aligned. So that
a \implies\mframed{ \startaligned
\NC b \NC= c \NR
\NC e \NC= f \NR
\NC g \NC= h \NR
\stopaligned}
Comes as
+---------+
| b = c |
a => | e = f |
| g = h |
+---------+
15. Automatic numbering in subequations. In the attachment that you
sent, one has to number the subequations by hand. The trouble with
this is that if you rearrange the equations at a later stage, you
need to keep track of equation subnumbering.
These are all that I can think of right now. All these features are
available in latex. It will be great if context can support these
features (or a subset of thereof). I promise to document them if they
get incorporated :-)

One more request. Allow these align, gather environments to break
across a page. Allow the user some kind of customization, whether the
break can occur at a particular location or not.

Can this be enhanced to allow more than one alignment points?
For instance
f(x) = x²+b² = g(x) (1)
h(x,y) = x²-5y² = g_2(x,y) (2)
should be aligned at the each "=", currently - using \equalign(no) or
\startalign - one can only align at one.

At least this should be possible with \wall and \return (using the

#v+
a \wall = b \\

Again, this is a \wall-\return thingy, but \placeformula places the
number vertically centered...
#v+
\usemodule[nath]
\starttext
\placeformula
\startformula
a \wall = b \\
+c \\
+e \return
\stopformula
\startformula
a \wall = b \\
= c \wall + d \\
+e \return\return
\stopformula
\stoptext
#v-
cu, Adam.

Unfortunately, if I use nath, I can not use underbrace inside
\startstop align of nath. See a previous post of mine with the subject
'Nath bug?'. It will be nice if I can use both solutions.

Is there someway in which the formula numbering can be forced to be at
the bottom. Maybe by adding an option to setupformulae. Latex has a
class option ctags/tbtags which controls this.
