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.
this 'loose label' is one of the ugliest concept i can think of -)
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.
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
Fine by me. Your method is perfectly acceptable.
much if this 'complicated' math is not that complicated to support,see
attached file
Wonderful. I did not know that something like this can be done so easily in
context.
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)
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.
[snipped]
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.

[NTG-context] linenumbering
All, I have a document with several sections and would like to have lines numbered consecutively across all sections.

Re: [NTG-context] mode dependend character handling
Sorry for answering that late.
The correct way would be to define swiss as a language, because
then you can put a suitable redefinition inside the language
specifics, but the following hack will work as well and is a lot
faster to implement (please don't tell anyone I proposed this):
\enableregime[il1]
\let\normalssharp\ssharp
\def\ssharp{\doifmodeelse{swiss}{ss}{\normalssharp}}
Thank you, that works and is just the right solution for my problem.
Mojca's proposal:
\startmode[swiss]
\definecharacter ssharp {ss}
\stopmode
unfortunately doesn't work, at least not with utf regime and ec
encoding.

[NTG-context] columns issues
Hello wizards! The \startcolumns ... \column ... \stopcolumns block handling seems somewhat broken. Maybe these old columns are deprecated, but I guess they should work. (And I would like to document them.) Consider this: \starttext \input ward \startcolumns \input ward \column \input knuth \stopcolumns \input tufte \stoptext In this case \column works (it doesn't seem to work always), so that the left column is much shorter than the right one. But the following paragraph (tufte) is typeset just after the last line of the left column, so that some lines overprint. And with [rule=on] the rule is only as short as the left column. [option=background] also only considers the leftmost (or first in [direction=left]) column. Maybe this behaviour is sometimes useful, but I don't think it should be default. [balance=no] doesn't affect the balancing of columns, but flushes the page (i.e. the tufte paragraph moves to the next page). With [n=3] you see that it doesn't use the whole remaining page. The whole problem seems to be \column, because without that, everthing (?) works. I didn't find out what the options ntop, blank, height and align are for; I tried several values and nothing seemed to change. [The source is http://source.contextgarden.net/page-mul.tex but I don't understand too much of it.] After looking in the manual, I guess I should consider using paragraphs or columns sets for most of my use cases, but anyway...

[NTG-context] indenting in XML environment
Ok, after taking deep breath I'll try this issue again. I got
indenting to work after putting \noindenting inside its own environment.
However, the following code block stopped working recently and I
don't know why:
\defineXMLenvironment[body]
{\bgroup
\rm\setupwhitespace[none]
\setupindenting[small,yes]
\startcolumns[rule=on,n=2,tolerance=strict]
{\noindenting} }
{\stopcolumns
\egroup}
It just doesn't indent anything, even after removing the
{\noindenting} environment.

Since Taco's proposal is OK, you don't need this, but I'll reply
anyway. The problem is caused by wrong order of commands. If you
load ec encoding AFTER this command, your new definition of ssharp
will be overridden by the encoding definition again.
Compare:
\enableregime[utf] % may be whatever, no influence
\startmode[swiss]
\definecharacter ssharp {ss}
\stopmode
\usetypescript[modern][ec] % or texnansi
\setupbodyfont[modern]
\starttext
Maß Bier! % fails (prints ß)
\stoptext
with:
\usetypescript[modern][ec] % or texnansi
\setupbodyfont[modern]
\startmode[swiss]
\definecharacter ssharp {ss}
\stopmode
\starttext
Maß Bier! % prints ss
\stoptext
(Since ec encoding is the default one on my system, I had to use
texnansi in order to make the example fail.)
If you use a slightly longer variant
\startencoding[ec]
\startmode[swiss]
\definecharacter ssharp {ss}
\stopmode
\stopencoding
than the order of commands doesn't matter any more (but then the
automatic conversion will only work for the ec encoding).
But now my question for Taco: why does your example work in both
cases? Does \def have a higher priority than \definecharacter?

[NTG-context] layer question
Consider this example:
\definelayer[extras]
[width=\paperwidth,
height=\paperheight]
\setlayer [extras] [x=2cm, y=5cm] {something}
\setupbackgrounds[page][background=extras]
This is ok, the placement is relative to the upper left edge of the
paper.
But following the Details manual, I should be able to use
\placelayer[extras]
instead of the background stuff.
But then the placement is relative to the upper left edge of the text
area.
Is this intended?

mode processing is based on modes that are in effect

the typeset time. This would work:

OK, thanks Taco. Now I understand the problem. I always compiled with or without
texexec --mode=swiss
which worked fine. If mixing modes within the same document is
required (\enablemode/\disablemode[swiss]), it fails of course (I
didn't think about it).

ptext/p
ptext/p
ptext/p
