This is mainly for convenience, it can be avoided but it would be easier with it.

I think there should be a \sign text macro so that you could do...
var x=1,y=-2
src<<"\sign[x]"
src<<"\sign[y]"

And it would output "+1" and then "-2"

Just a thought I had randomly. Something small that could be added easily.

It'd be quasi-useful, but at this point the prospect of adding new text macros is pretty bleak. You're better off soft-coding it.

proc/NumPlus(n)
  if(n<0) return "[n]"
  return "+[n]"


That also returns +0, but then when I've used this it's been for a Roguelike, where +0 makes sense. If you don't want that behavior, just change the if() to if(n<=0) instead.

Or for a slightly fancier version:

proc/NumPlus(n) return "[n<0?"":"+"][n]"


I think I'll stick that into a snippet, although I don't think it's unusual enough to mandate an actual post in my database...
