I was attempting to make some fun with this thread.

More seriously, \( expression \) was already an attempt to come up with
something "better". I am risking to state that $expression$ and
\math{expression} are two good solutions for ConTeXt and that
\m{expression} is, at best, just useless. Furthermore, any suggestion to
depreciate $expression$ is, in my opinion (and apparently in the
opinion of others), ludicrous.

Alan

P.S. I am a present writing a chapter on mathematics for a small
introduction on typesetting with ConTeXt, so this discussion is
highly relevant.

We should DROP \m{} (in favor of \math{}) as this is really useless. I
suppose that in the beginning (and according to Aditya's blog), this
was some attempt to be as short as $...$, well only two characters
longer. Since no one in his or her right mind would regularly use
\m{...} in favor to $...$, as Aditya himself suggests above, it is
redundant. Indeed, \math{...}, context.math(¨..."), \mathematics{...}
and context.mathematics("...") have their utility. See also below.

Hans, you forgot: ¥x^2¥, ₽x^2₽, ₱x^2₱, ₹x^2₹, ...
Besides, U+0024 comes from ASCII and all programmers know that it is a

The \math or \mathematics variant should work in all such cases.

I spy...

I would suggest that one would set (inline) math spacing and other
options (like \mathscriptsmode) globally for a document, as it would not
be very good style to mix and match.

However, I can see situations where one might want to tighten spacing
in order to fit a particular expression within a line or in a table,
for example. Here, \math[options]{expression} is a reasonable syntax,
yet I cannot foresee ever using the very cryptic \m{} for any reason:
it is just plain ugly! (No TeXie would ever find $$ as

Sorry, Wolfgang. You’re right, I forgot to tell-

I want to avoid tagging each cell to get this:

Of course, you’re right. I totally overlooked it. I misread
\installframerenderer.

I wonder whether a common \installframerenderer would make sense here.
It would simplify code writing. Or at least I think it may be useful.

\setuphead[chapter][

In the current beta, they are unnumbered. Has the syntax changed?


Besides, according to wiki, "number=yes" should force a numbered 
title, while uncommenting these lines in fact suppresses the number in 
TeXLive (and does not help in beta).


Is this a bug/work in progress or am I doing something wrong here?

You’re missing the start/stop-commands for the bodypart.

\typebuffer

Also have a look at Aditya's vim syntax highlighter module which is
great.

Hello,

\typefile allows to specific syntax highlighter, e.g.
\typefile[TEX]{file.tex};
\typebuffer does not (AFAIK).

It would be useful to have:

\startbuffer[demo]
   \startitemize
 \item Hello!

\stopbuffer

which would get the original code and its result:

Is it possible somehow?


the 'option' key does that (option=tex)

[NTG-context] Buffer with syntax highlighting

Re: [NTG-context] Deprecated $…$ for inline math?

On 2/17/2016 8:31 AM, Otared Kavian wrote:

I agree totally with Alan in saying that the inline math signals $\cdots$ 
should NEVER be left out from ConTeXt, or even become deprecated.


that was never the intention (as one can always run in asciimode) but 
what's being discussed here is more robust tagging (could be for editor 
lexing or other purposes)


also, but don't tell alan, there is this:

\m[i:tight]{}

i:default, i:tight, i:half, i:fixed


Indeed many people move mathematical texts from one file to another one, in 
order to be able to typeset or print it either with ConTeXt, or other 
macro-packages. Other situations include when one is collaborating with other 
people using TeX, where inline math between two $ signs  is now well 
established. Also in many situations people may use ConTeXt  for well presented 
documents, presentations and so forth, while the same text may be published in 
a scientific journal where one has to use their own formats, usually an ugly 
flavor of LaTeX, since, unfortuantely, up to now I don’t know of any 
mathematical journal where one can submit a TeX file written with ConTeXt 
macro-package.


and even if dollars were just dollars one could easily make then 
math-shift characters again


\catcode`\$ = 3

(or pounds on an brittish keyboard or ...)

btw, in math mode some chars are special too (primes for instance, a 
headache character)



Best regards: OK

Clearly, an equation to which one might want to have a reference
math should appear rather as displayed math.


While I agree on that one, writing \math{x^2} clearly states what it
is. TeX tradition aside, dollar signs make no sense here and you
have to manually match beginning and end. Braces are matched
automatically (probably depends on the editor as well).


\math{x²} states what it is. However \m{x²} is cryptic and, although
only two characters longer than $x²$, is infinitely less readable than
the dollar-delimited variant, even now to MS/Word users who have ever
used the equation editor.

When typing sentences containing lots of math, having many \math{}
commands becomes unwieldy, but, in the end, this becomes a
question of personal taste.

 Thanks a lot that works.

 I've a follow up question. I'd like to wrap the `\setgvariable` in a a
 paragraph like thing. I found out about annotations, which look like
 what I've after.

 Though sadly I get an error message (! Undefined control sequence) when
 I use annotations. It works when I hard-code a value within the
 annotation, but it doesn't if I use the contents of the annotation.
 I've
 also tried it the `\placeannotationcontent` way, but there I get the
 same error. Here's the full example:

 \starttext

 \definelayer [pagenumber][width=\overlaywidth,height=\overlayheight]
 \defineoverlay[pagenumber][{\directsetup{pagenumber}\tightlayer[pagenumber]}]


 \startsetups pagenumber
 \setlayerframed
 [pagenumber]
 [preset=rightbottom]
 {\getvariable{table}{p}}
 \stopsetups

 \define[2]\PageWrapper{\setgvariable{table}{p}{#2}}

 \usemodule[annotation]
 \defineannotation
 [pn]

Thanks again. It's not quite what I'm after as it would be on the same
line as the last in the paragraph (or one after), but another cell might
be higher. So it might not always end up at the absolute bottom.

Anyway, you all provided already so much help. As I'm a Context newbie
I'll just take the to play around with the stuff and see if I can come
up with something that suits my needs. I'll start a new thread in case
I've a more more specific question.

Cheers,
  Volker
