[NTG-context] Question about defining a math macro
Hi,
Can I define a math macro, say \EXP that does the following:
1) \EXP{something} gives me, say E(something)
2) \EXP_a^b{something} gives my E_a^b(something)
That is, I want to write a macro that will only be used in the math
mode, that does something with its argument. But, I also want it to
handle _ and ^ if they are present.
The only method that I can think of is to check _ or ^ with
\ifnextcharacter and go through all 5 cases (nothing, only _, only ^,
_ followed by ^, ^ followed by _) but this seems very inefficient. Is
there a better way?

Actually, there is, by using a bit of black magic in the
macro definition:
\def\EXP#1#{\bgroup\def\EXParg{#1}\doEXP}
\def\doEXP#1{\mfunction{E}\EXParg({\rm #1})\egroup}
That extra hash mark has the effect of putting everything
upto the next explicit left brace into #1.

[NTG-context] simplecolumns
\simplecolumns have served me well. However, it seems a bit shy to respond to \setupcolumns (although in file page-mul.tex the definition of \setupcolumns preceeds that of \startsimplecolumns). For example, the following typesets 2 columns instead of 4; to set 4 columns \startsimplecolumns[4] is required. \starttext \setupcolumns[n=4] \startsimplecolumns \input tufte \stopsimplecolumns \stoptext Can someone tell me if \setupcolumns has any effect on the typesetting of simplecolumns?

Re: [NTG-context] Math Sets (ConTeXt port of braket.sty)
Hi,
I find myself writing a lot of probability expressions where I want
the delimiters to scale automatically, and | (conditional sign) to
scale automatically, and the spacing around | to be correct. In LaTeX,
I used to use braket package to do this. Since moving to ConTeXt, I
was doing this by hand, but wring a lot of
\EXP\left\{ ... \,\middle\, ...\right\} and \Pr( ... \mid ...)
soon became a pain to read and write. So (thanks to Taco's first hand
knowledge of why TeX is Turing complete), I have written the following
macros:
\unprotect
\definesystemvariable {ms} % Math Set
\def\mathsetmiddle{\,\middle\mathsetparameter\c!middle\,}
\let\currentmathset\empty
\def\mathsetparameter#1%
{\executeifdefined{\??ms\currentmathset#1}{\executeifdefined{\??ms#1}\empty}}
\def\definemathset
{\dodoubleargument\dodefinemathset}
\def\dodefinemathset[#1][#2]%
{\getparameters[\??ms#1]
[\c!text=,\c!left={\{},\c!right={\}},\c!middle=\vert,#2]
\setvalue{#1}{\dododefinemathset[#1]}}
\def\dododefinemathset[#1]#2#%
{\begingroup
\def\currentmathset{#1}
\mathcode`\|32768
\let|\mathsetmiddle
\def\mathsetarguments{#2}
\dodododefinemathset}
\def\dodododefinemathset#1%
{\doifsomething{\mathsetparameter\c!text}
{\mathop{\mathsetparameter\c!text\mathsetarguments}}
\left\mathsetparameter\c!left#1\right\mathsetparameter\c!right
\endgroup}
\protect
which allows me to do
\definemathset[EXP][text={\mfunction{E}}]
\definemathset[PR][text={\mfunction{Pr}},left=(,right=)]
\starttext
Correct spacing around the vertical bar.
\startformula
\EXP{f(X) | Y} = \sum_{x} f(x) \PR{x|Y}
\stopformula
Correct scaling of delimiters (as correct as left and right give you)
\startformula
\EXP{\sum_z f(X,z) | Y} = \sum_{x,z} f(x,z) \PR{x,z|Y}
\stopformula
Correct handling of sub|/|super scripts
\startformula
\EXP_X{f(X) | Y} = \sum_{x} f(x) \PR{x|Y}
\stopformula
Is there anyone else interested in this kind of stuff? I have not
ported all the features of braket.sty, but only those that I needed.
Other should not be too difficult to port.
Hans and Taco: Does it make sense to add these to the core? If so, I
can polish the macros a bit (add a \setupmathsets command).
Aditya
I think I will need it near in the future. Thanks for nice the nice works.
