Re: FVWM: Arithmetics?

I found a simple solution that makes arithmetics more readable, at least:

  DestroyFunc Let
  AddToFunc Let
  + I PipeRead `bash -c 'let "FVWM_LET_TMP=$1"; printf "SetEnv $0
  $$$$FVWM_LET_TMP"'`

That way I can easily write complicated arithmetic expressions, eg.

  Let FVWM_TMP "($[desk.n] >= $[FVWM_HDESKS]) ? -$[FVWM_HDESKS] : 0"

It also is independent of the shell "sh" since "bash" is specified
explicitly.

What do you think of it? If you think it could be added to the FAQ, I'm
willing to write the entry.
