Easy way to auto-label [closed]

Question

I defined a new paragraph with one counter in this way: \def\newparagraph{\paragraph{\counter}} Is there a way to release this kind of label?

\label{\value{chapter}.\value{\counter}}

Answer 1

You surely can do

\newcounter{leo}
\newcommand{\newparagraph}{%
  \refstepcounter{leo}%
  \paragraph{\theleo}%
  \label{\thechapter.\theleo}%
}

but the label will serve no purpose whatsoever.

Suppose that, at one point when writing the document, your \newparagraph gets the number 4.1 (second numbered paragraph in chapter 4). You'll happily refer to it by \ref{4.1}. The next day, you decide that, after all, there should be another numbered paragraph before the already written one. You'll need to chase down all \ref{4.1} (and the ones of the form 4.x) in order to change them for reflecting the current situation.

The next day you (or your thesis advisor) decide that, after all, the two numbered paragraphs should be merged into one. And so on and so forth.

Do, instead,

\newcounter{leo}
\newcommand{\newparagraph}{%
  \refstepcounter{leo}%
  \paragraph{\theleo}%
}

and use

\newparagraph\label{wonderful} This is my wonderful paragraph

so you can refer to it by \ref{wonderful}.
