Particular environment LaTeX help

  1. Sep 8, 2006 #1
    Hey all!

    I'm trying to learn [tex]\LaTeX[/tex], and so far I'm doing fine. However, I would like to know if it is possible to be able to find out if a particular environment is in use at a certain point. Basically, I was wondering if something like:

    \isInUse{math}

    exists in LaTeX. Does anyone know?

    Thank you all!

    why not:

    [tex]sin (math)[/tex]

    ?

    Hmmm... I don't think I understand how this command can help me finding out if the math environment is in use or not...

    I've never heard of such a thing. I don't really see a need for it. Why would you need something like that?

    I don't think any of us know what you're asking for, its not clear in the least. Are you talking about so you can tell if an environment is in use in a certain area while you're editing? Or are you talking about during compilation?

    You're right, perhaps that was not very clear. I want to be able to tell if an environment is in use in a certain area during compilation. Something that may return a boolean, to be used with some other package (I believe there is a if-then package or something like that... right?).

    As far as I know, the answer would be no, but there are a lot of custom home-made packages I'm not aware of. What are you trying to do that you would use this for?

    Call me lazy, but I'd like to make a new command to quickly display a norm, something like \newnorm{x+y} (to display [tex]\|x+y\|[/tex]), whether I'm in the math environment or not.

    You can run latex "interactively" which will give you the verbose on what classes you're using - possibly also style files???

    However, style files are loaded from the preamble (\usepackage{}) - so you should be able to see from your tex file...

    use \ensuremath{}

    Thats what I use to set up macros to use in text. Something like

    \newcommand{\Msun}{\ensuremath{M_\odot}}

    Then I can use \Msun anywhere, in text or math environment and its automatically typeset as math.

    :!!) Exactly what I needed! Thank you!
