General ⇒ A new env. like description items

[tufflax]

Hey!

Let's say I wanted to make a new environment that looks like a description list item, that is, the first line is not indented, but the rest of the lines are. How can I do that?

And, just out of curiosity, could I make an environment that would indent every two lines?

Search the forum for the xlist environment. This could be suitable solution for your problem. You can also try customize the standard list environments with enumitem.

Thank you for your answer!

Oh, maybe I wasn't clear enough... I dont want to make some kind of list, I want to make an env that looks kind of like a description item, but that has nothing to do with some kind of list.

Dou you mean a hanging indent? Try this:

Code: Select all

\parindent=0pt
\hangindent=24pt
\hangafter=1
Text...

Yes, with the \parshape command you can use every possible combination of indentations:

Code: Select all

\newcommand*\AltIndentParShape[2]{%
  \ifnum#1>0 %
    0pt \linewidth \dimexpr(#2) \dimexpr\linewidth-(#2) %
    \expandafter\AltIndentParShape\expandafter{\number\numexpr#1-2}{#2}%
  \fi
}
\newenvironment{AlternatingIndent}[2]{%
  \everypar{\parshape#1 \AltIndentParShape{#1}{#2}}%
}{}

The environment expects two arguments: the number of lines to which it should be applied (if you want it to apply to all lines of each paragraph, just set this to a value that is greater than the number of lines in the largest paragraph inside the environment); and the indentation for lines with even number (can be any dimexpr). For example:

Code: Select all

\begin{AlternatingIndent}{100}{6pt+12pt}
... Text ...
\end{AlternatingIndent}
