I have the following problem: I need some \boxdiag and \boxbslash symbols, but I'm still too much of a TeX n00b, so I have no idea what to do when packages clash. In this case, any package I tried that had a \boxdiag symbol in the end clashed with amsmath (?), \vec being found red-handed. Since I am a very sneaky n00b, I found a way to at least have a neat \boxbslash emulator: \mathrlap{\smallsetminus}\square. Note that \smallsetminus perfectly fits into \square. Which \diagup doesn't. So, I'm looking for \foobar with \foobar:\smallsetminus=\diagup:\diagdown. (Even tried \mathrlap{\angle}\square :-) Changing the font size of \diagup doesn't seem to work either inside \mathrlap (its a math environment). Or do you have another idea that doesn't involve mutually crosschecking 20 packages?

  • I would rather guess that font packages might have clashed with amssymb rather than amsmath. Is your question basically "how to get \boxdiag in a standard CM setup"? – campa Jun 18 at 13:40
  • a) you're probably right with the first, b) what's a CM? (me n00b, n00b ;-) - you're probably right with that too in any way) – Hauke Reddmann Jun 19 at 9:28
  • Sorry: CM stands for Computer Modern, the standard font used by (La)TeX. If you are using some other font packages you should provide a minimal working example with what you have tried so far. – campa Jun 19 at 9:40

Fits within the existing size of \square. Let the bowling commence!

If your math font changes, the only tweak necessary are on those \stretchrel* optional arguments. For example, with txfonts loaded, the option should be [72] for all 4 math styles.

  • Neat, although I even don't want to know what horror happens if I add those packages :-) (I "solved" the incorrect size when using as subscript by "tiny" before the symbol.) – Hauke Reddmann Jul 18 at 17:05
  • @HaukeReddmann Well, amssymb is so widely used as to be proofed against all evil. As to the other two packages, I wrote them, so if horrors happen, come blame me, and I'll see what can be done. – Steven B. Segletes Jul 18 at 20:30

By chance, I noticed that I already have the package graphicx loaded (without clashes), which means I can rotate a symbol. Thus the gruesome \rotatebox[origin=c]{90}{$\mathrlap{\smallsetminus}\square$} (which of course I meanwhile macro-ed with \newcommand) does the trick without any side effects, and looks nearly as perfect as the native box-with-diagonal symbols from the mentioned packages. Case closed :-)
EDIT: Or at least nearly. This hack can't be used inside a caption environment (throwing an incomplete \iffalse error, as it seems - still experimenting), and when used as index in math mode, utmost care must be taken of brackets and dollars in the right order.

  • The problem with \caption should vanish if you use \DeclareRobustCommand instead of \newcommand. – campa Jul 16 at 14:56
