General ⇒ Infix commands

[yrogirg]

Hi! How do I define infix commands, e.g. \over?

[localghost]

Please explain what you are aiming at. The command \over already exists as a plain TeX command and produces fractions in math mode.

I think the OP means commands that work:

Code: Select all

<arg1> \macro <arg2>

to which the answer is "you can't", really. For example, \over isn't exactly infix. Try something like:

Code: Select all

{Some text {arg} \over {second} arg}

as see that it applies to everything in the outer group.

Thank you, that's what I need to know.
