Is there an alternative way to enter multiple arguments to LaTex newcommand constructions? I have defined
\newcommand{\nuc}[2]{\ensuremath{^{\text{#1}}\text{#2}}}
and I would like to call the command through
\nuc{12,C}
and not
\nuc{12}{C}.
I have created other commands with even more arguments and my poor pinky can't handle all the brackets.
Thanks!
Maybe you will like it.
\def\nuc #1,#2.{\ensuremath{^{\text{#1}}\text{#2}}}
Sample of using:
\nuc 12,C.
Note. Use the dot at the end.
I like to praise perltex for defining complicated functions. This isn't complicated, but you can extend it quite impressively.
%myfile.tex
\documentclass{article}
\usepackage{perltex}
\perlnewcommand{\commafrac}[1]{
$input = shift;
@inputs = split(/,/, $input);
return "\\ensuremath{\\frac{$inputs[0]}{$inputs[1]}}";
}
\begin{document}
One half is $\commafrac{1,2}$.
\end{document}
Compile with perltex --latex=pdflatex myfile.tex
. I know that \\frac wasn't your example, but I find it a visually appealing one.
Use plain TeX \\def
:
\makeatletter
\newcommand*{\nuc}[1]{\nuc@#1\@nil}
\newcommand*{\nuc@}{}
\protected\def\nuc@#1,#2\@nil{\ensuremath{^{\text{#1}}\text{#2}}}
\makeatother
As fas as I know \\nuc{12}{c}
is the only way. If you don't want to put all the "}{"s, let the editor do it. Write \\nuc{12,c}
first, then replace all commas with "}{"s.
