Loop/iteration in LaTeX

[ogheo...@gmail.com]

Hi,

I MetaUML's manual, I'd like to replace sequences like:

\metaumltest{picture_stack}{1}
\metaumltest{picture_stack}{2}
\metaumltest{picture_stack}{3}

or

\metaumltest{state}{1}
\metaumltest{state}{2}
\metaumltest{state}{3}
\metaumltest{state}{4}

with a for or loop. What is the best way of doing this in LaTeX?

Thanks in advance,
Ovidiu

Hi,

I think the simplest way is using the commands provided by the package
ifthen. But, if you prefer the hard way, and doing it in TeX, you can
use the \loop ... \repeat.
For instance:
\newcount\qq
\qq=1
\loop
\metaumltest{state}{\qq}
\ifnum\qq < 4 \repeat

package multido

\multido{\iA=1+1}{4}{\metaumltest{state}{\iA}}

Documentation for the package ifthen can be found here:

There is a \whiledo that may be what you're looking for.

(though it sounds like the multido suggestion is nicer)

No, no, it was programmed in Forth. See Genesis 1:12:

Thanks for the answer, but I'm having trouble with the code:

\newcount\qq
\qq=1
\loop
\metaumltest{font}{\qq}
\ifnum\qq < 3 \repeat

pdfLaTeX sais:

! Missing number, treated as zero.
<to be read again>
\protect
l.32 \ifnum\qq < 3 \repeat

Any ideas why?

[Herbert Voss]

\newcount\qq
\qq=1
\loop
metaumltest{state}{\the\qq}
\advance\qq by 1
\ifnum\qq < 5
\repeat

This works just fine, here's my final code --- in case someone else
needs something similar:

\usepackage{multido}

\newcommand{\metaumltest}[2]{Test #2 --- \\
\includegraphics{fig/test_#1.#2} \\ }
\newcommand{\metaumltests}[2]{\multido{\iA=1+1}{#2}{\metaumltest{#1}{\iA}}}

\subsubsection{Class tests}
\metaumltests{class}{14}

Thanks,
Ovidiu

aaaaaaaaaargh! Yes, of course.
