I hope someone can help me with this problem.
I'm writing a technical paper and make frequent reference to leidenfrost
temperature. I have abbreviated this with:
\newcommand{\tleid}{$ T_{Leid}$}
Now I can just put \tleid in normal text. The first problem is that this
will ignore a normal space after \tleid. If I put a hard space in the
definition, it wouldn't work if followed by a punctuation mark. The second
problem is that I would like to be able to use the same command if I'm
already in the math mode ( although I could live with \tleidm or something
similar).
Is the answer obvious to anyone?

Balint <lba@kolvi.hut.fi>, and allbery@NCoast.ORG (Brandon S. Allbery KB8JRR). TeX will not treat a command as an ordinary word, I can stick {} after each use, or a \ if I really want a space after. I can write it to detect math mode like this: \newcommand{\tleid}{\ifmmode T_{Leid}\else$ T_{Leid}$\fi} Thanks. -- Peter Halvorson -- Nuclear Engineering Program Georgia Institute of Technology, Atlanta Georgia, 30332 uucp: ...!{allegra,amd,hplabs,ut-ngp}!gatech!prism!ne201ph Internet: ne201ph@prism.gatech.edu -- peter@fission.gatech.edu

Sure, I have several macros that I use this way. But it is always annoying that I sometimes forget to put in the extra \ in the all places where I need a space. Has somebody got a macro that will put in a space unless the next character is a punctuation mark? -- Ron Greenberg rig@umiacs.umd.edu

I wrote a macro \AfterMacro, a couple of years ago, that I sometimes
use this in macro packages intended for people with NO TeX
experience at all. Myself, I think it's better to use the \Tleid\
notation. You can use \AfterMacro in macro definitions, that expands to
abbreviations or names or formulas.
-------------cut-------------------
\def\AfterMacro#1{\if#1,,\else % Feel free to add more punctuation
\if#1..\else % marks, as you need them.
\if#1!!\else
\if#1??\else
\if#1::\else
\if#1;;\else
\if#1''\else
\if#1))\else
\if#1-\-\else % NOTE: '-' epands to '\-'
\ #1\fi\fi\fi\fi\fi\fi\fi\fi\fi}
\def\tEx{\TeX\expandafter\AfterMacro}
\def\jon{Jonathan\expandafter\AfterMacro}
\def\Tleid{\ifmmode T_{\rm Leid}\else$T_{\rm Leid}$\expandafter\AfterMacro\fi}
This is how to use \tEx in a sentence, which could also end with \tEx.
This is how to use \jon in a sentence, which could also end with \jon.
\jon's car (owned by \jon) is green. You can use \Tleid (Yes,
\Tleid!!) in the text or in a formula $\Tleid < 2\Tleid$.
