I have a master style file of macros, which I use for all of my documents. Is there something I can add to the preamble of a particular file so that it ignores some specific macro from my style file?

For example. My style file includes my custom shortcut \foo. Now I am writing a specific document, and I want to use some unusual symbol that is part of some random package I never use. So I add this package to the preamble of this document, to get the command for the unusual symbol. But this package happens to use the command \foo for some other thing I don't care about, and so now I get the \foo already defined error when I try to compile. I would like to add something to the preamble of this document so that it ignores \foo in my style file. Is this possible?

  • \renewcommand{\foo}{} or for a symbol savesymbol package

  • @ChristianHupfer It's a symbol, which I assume is why \renewcommand{\foo}{} doesn't work. I am not familiar with the savesymbol package, and I couldn't figure out how to implement it. However, when searching for info on savesymbol, I found this question, which provides an answer. In particular, I add \let\foo\relax to the preamble between \usepackage{mymacros} and \usepackage{randompacakge}. Should I delete the question? May 14, 2016 at 14:30

    \let\foo\relax can work but you won't be able to access the original definition then

    I made an error as well: The name is savesym, not savesymbol, but the command is called that way, sorry about!

Here is the savesym way of getting rid of this problem:

\savesymbol{foo} should work, after that say \origfoo to access the old version.

The classical conflict appears for example with bbding and marvosym packages:






Original version: \origCross

Redefined version: \Cross

    Thanks for spelling out how to use the savesym package. May 14, 2016 at 14:49
