I often use short macros in mathematical formulas for frequently used symbols, e.g. d x for a differential dx or, say, v if I need a vector v very often in my text to make things more readable.
However, I get a clash with predefined macros because d stands for a dot under the next character and v for the hacek accent, which I don't want to override (maybe I need them in the bibliography...).

So, I came up with the following to override those macros only in math mode:

documentclass{article}



usepackage{everyhook}

newcommand{mathdef}[2]{%

  PushPostHook{math}{expandafterdefcsname #1endcsname{#2}}%

  PushPostHook{display}{expandafterdefcsname #1endcsname{#2}}}

mathdef{d}{mathrm{d}}%



begin{document}

  d x  is an x with a dot below and $int f(x) d x$ is an integral over $x$.

end{document}

However, I would like the command to be defined like normal macros too, i.e. mathdef{d}{mathrm{d}}, and also be able to take arguments, but all my experiments with expandafter, unexpanded, etc. didn't work out and led only to the usual strange error messages. Any hint how I can do that?

Furthermore, do you think there is a big performance penalty using everymath like that in a large document?
