Using the cleveref package for reference ranges, I'd like to change the standard \crefrangeconjunction from _to~ to _-_, where the underscores represent spaces. Issuing


I find the spaces are much too large. Defining instead


is more compact and looks much better in my eyes but has the disadvantage of breaking at line ends.

Is there an unbreakable space smaller than ~?

    btw: most typographical guidelines would use n-dashes, not hyphens, for this purpose and would not have spaces (let alone full spaces like ~) around the dash. – Florian May 31 '17 at 12:33

  • @Florian I'm aware of that. In fact, the cleveref documentation itself says "it is perfectly reasonable to define it [\crefrangeconjunction] to be an endash “--”". Call me crazy, but I really can't stand the look of it, though, so I'll stick with a hyphen for now. :) – Casimir May 31 '17 at 13:00

It's - that's causing the break, not \,.




  a\unbreakablethinspace-\unbreakablethinspace b

  a\unbreakablethinspace\mbox{-}\unbreakablethinspace b


Hiding - in a box disallows the possibility of breaking at it.

I defined \unbreakablethinspace because \, might give surprises if used at the beginning of a paragraph. You can simply use \, if you're sure it will always go after a word.
