I would like to define commands with semantics similar to e.g. + in math mode. For instance,

$(x+y)$

produces an equation with some spacing around +, whereas

$(+)$

produces an equation with less (or no) spacing around +.

The reason is that I would like to write something like

$\token{repeat} \token{skip} \token{until} b$
$\token{skip}$

Where tokens are follwed by a space in the first case, but are not in the second. In a way, I'd like something similar to xspace, in math mode.

Any suggestions?

  • + gets it space from being a \mathbin but \mathbin{\hbox{#1}} doesn't do what you want.... – David Carlisle Sep 7 '13 at 11:21

Perhaps mathop spacing is what you are looking for.

enter image description here

\def\token#1{\mathop{\hbox{#1}}}

.$\token{repeat} \token{skip} \token{until} b$.


.$\token{skip}$.
