Text Formatting ⇒ Output of a counter BEFORE counting

[nikolapoljak]

Hi,

perhaps this is simple, but I just can't get my head around it... is there a way to output a final counter value before the counter actually starts? For example, an output like:

Item count:2

1. first item
2. second item

I am using MacTex with the XeLaTex processor on TexWorks.

Please help, it is sort of urgent. Thanks

[nikolapoljak]

Solved, thanks.

Hi,

welcome to the board!

If fellow readers would solve your problem, they would post the solution. Generally it would be good if you would post your solution also if you found it yourself. Imagine, google users would come here searching for their problems and find it discussed, but only a "Solved" without any solution... would be frustrating.

So if you would find the time later, it would be nice if you would add a solution. I guess it could be done by storing the final counter value in the .aux file.

So, I didn't solve it after all... I thought the package totcount would help me, but not really. Here is the problem:

If I write something like:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
\vskip 5mm
\newtotcounter{Nature}
\begin{enumerate}
\usecounter{Nature}
\item{Blablabla}
\end{enumerate}

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Run LaTeX here

then I can use \total{Nature} anywhere in the text and it turns out fine. BUT, all the items in the list start with a zero.

On the other hand, if I use

Code: Select all

Code, edit and compile here:

1
2
3
4
5
\vskip 5mm
\begin{enumerate}
\newtotcounter{Nature}
\item{Blablabla}
\end{enumerate}

than the items are enumerated correctly (1,2,3...), but I can't seem to use \total{Nature} anywhere.

Any suggestions?

Btw. I am not using \usepackage{enumerate}, it is just the usual enumerate environment.

[nikolapoljak]

OK, so here is the simple workaround:

use package totcount and do:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
\newtotcounter{Nature}
\begin{enumerate}
\addtocounter{Nature}{1}
\item{Blablabla}
\addtocounter{Nature}{1}
\item{Second item}
\end{enumerate}

and then you can use \total{Nature} anywhere in the text and still your enumeration will look fine. Hopefully it helps someone.

Hi,

\stepcounter{Nature} (or \refstepcounter{Nature}) would be a bit easier to write.
Thanks for sharing your solution!

Wouldn't it be even nicer to instead of manually adding \addtocounter every item declare a macro, for example:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
\documentclass{amsart}
\usepackage{totcount}
\newcommand{\Item}[1]{\stepcounter{#1}
\item}
\begin{document}
\total{Nature}
\newtotcounter{Nature}
\begin{enumerate}
\Item{Nature}Blablabla
\Item{Nature}Second item
\end{enumerate}
\end{document}

Makes it a lot easier. If you use only one counter you could include the counter name in the macro of course, but then I'd rename the new command a bit to distinguish it better from the default \item.

[Stefan Kottwitz]

You could set the total counter to be the most recent value of the enumerate counter enumi:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
10
11
12
13
\documentclass{article}
\usepackage{totcount}
\newtotcounter{Nature}
\begin{document}
The total number will be \total{Nature}.
\begin{enumerate}
  \item{First item}
  \item{Second item}
  \item{Third item}
  \item{Fourth item}
\end{enumerate}
\setcounter{Nature}{\value{enumi}}
\end{document}

Good idea, which is flexible.

If each item of an environment would be counted, it would be good to define a new enumerate environment (with a different name) which works like enumerate but updates the total counter in the environment's end definition, as in my previous post.

When defining a new environment you should probably use \addtocounter and not \setcounter in case you want to use two lists which total to the same counter. When you have only one list this makes no difference as the initial value is zero anyway, am I wrong?
