I have the following code which I put inside the preamble of my LaTeX documents:


In this case, that means that when I'm writing my lecture notes I can just use \modulecode to refer to the module code. I'm trying to create a style file to use for my lecture notes, and want to have some way that I can define what the module code is (that is, some way of setting the variable) in each document, so that I can then refer to it as above using \modulecode.

I can't seem to find how to do this through Google, but I'm sure it must be a fairly simple request. Any ideas?

  • Basically it sounds like passing a parameter to the package. Did you have a look at some package guide? Jan 4, 2011 at 14:42
  • I've had a look at that, but I'm not sure exactly what I need to look for. I could do this by passing a parameter to a package, but I can't see how to do that with passing strings rather than just options. What I was actually thinking of was creating a command (using \newcommand possibly) in the style file that would allow me to do something like \setmodulecode{COMP6023} in my document. That would seem to me to be the easiest way - and I'd guess it is fairly simple. Is that so?

  • I thought of packages like hyperref and fixme, which support options of the form key=value. Jan 4, 2011 at 15:09
  • That sounds good, as an alternative to the other answers presented. Is it fairly easy to do that?

  • I don't know. But it's a good question! Jan 4, 2011 at 15:25

1 Answer 1


do you mean something like this?


if you have it inside a style file then do something like


to prevent overwriting by a user. Alternatively use \setmodulecode{} for the first definition.

  • You were quicker. Just one thing: you wrote \setmodulcode instead of \setmodulecode. Jan 4, 2011 at 15:07
  • Thanks - that works well :-) The only problem I have is that I then want to use \modulecode in a bit of fancyhdr code as below. This code is inside my style file, but is failing - presumably because it can't see \modulecode at the time that it is run (as it is defined in the preamble of the document). Is there a way around this: \fancyhead{} \lhead{\modulecode} \rhead{\lecturetitle}

  • @robintw: make your definitions before you load fancyhdr. If it doesn't work create a minimal example.

  • As usual, in the process of making the minimal example I found the problem. Apologies - I really must do that before asking! Thanks for your help.
