+ as plain vanilla math character

+ as plain vanilla math character

[Oliver Buerschaper]

Dear all,

I'm wondering how to typeset a sequence of pluses such that each plus  
is placed with "normal" math character spacing around it ... In this  
snippet I guess a plus (or at least the majority of pluses) is simply  
treated as a binary operator with appropriate spacing:

---

\def\ket#1{\lvert#1\rangle}

\starttext

Note the spacing in
\startformula
\startmathalignment
\NC\ket{+}\NR
\NC\ket{++}\NR
\NC\ket{+++}\NR
\NC\ket{++++}\NR
\NC\ket{000}\NR
\stopmathalignment
\stopformula

\stoptext

---

Cheerio,
Oliver

This should normally work, but it depends on the current math
encoding (see the math-xxx.tex files  in the distribution):

   \definemathcharacter [+] [ord] [mr] ["2B] % [bin] is default

Best wishes,
Taco

Just tried this but to no avail :-( It seems like the definition  
isn't found at all:

---

\def\ket#1{\lvert#1\rangle}

\startmathcollection[default]
	\definemathcharacter [myplus] [ord] [mr] ["2B]
\stopmathcollection

\starttext

Note the spacing in
\startformula
\startmathalignment
\NC\ket{+}\NR
\NC\ket{++}\NR
\NC\ket{+++}\NR
\NC\ket{++++}\NR
\NC\ket{\myplus\myplus\myplus\myplus}\NR
\NC\ket{000}\NR
\stopmathalignment
\stopformula

\stoptext

---

Is this caused by some wrong math encoding scheme? Or is there  
something else that I miss?

Puzzled,
Oliver

Probably because "+" is done already.

This will work, except that you need \definemathsymbol,
not \definemathcharacter.

   \startmathcollection[default]
   \definemathsymbol [myplus] [ord] [mr] ["2B]
   \stopmathcollection

Best wishes,
Taco

That's it, stupid me ... now it works like a charm. Many thanks!

Oliver
