No empty line before an item list

[Cecil Westerhof]

In a LaTex document I defined:
\newenvironment{myitemize} {
\begin{itemize}
\setlength{\itemsep}{0pt}
\setlength{\parskip}{0pt}
\setlength{\parsep}{0pt}
} {\end{itemize}}

In my document part I have something like:
To do this you need:
\begin{myitemize}
\item A plan
\item Steps to implement the plan
\item The will to take the steps
\end{myitemize}

But I then get an empty line between
To do this you need:
and:
A plan

How can I remove this empty line?

Use the enumitem package (it handles itemized as well as enumerated
lists), and say

\begin{itemize}[nosep]
...
\end{itemize}

That works. It also removes the empty line after, but that I can
easily restore with:
\vspace{\baselineskip}

That's an interesting use case: your short lists always come at the end
of a paragraph, so you need no space above but normal space below?

This sounds like a good idea for a [noaftersep] option :-)

Well I am not sure always, I just started with using LaTeX. But at the
moment I use them for something like:
The things you learn are:
- First
- Second
- …

And I do not want:
The things you learn are:

- First
- Second
- …

I look into it.
No sleep for the wicked. ;-P

That's a very common requirement. But if a compact list occurs WITHIN a
paragraph (as your example), then if the text of the same paragraph
continues after the list, there should be no spacing after the list, eg

However, if it comes at the END of a paragraph, anything following it
must by definition be a new paragraph, so you may want to decide if
there should be space or not, depending on your rules for indentation
and your normal inter-paragraph space.

I use paralist so I'm not sure whether the following is transferable. In
my personal addons package, that is always loaded for anything, I have:

\newcommand\parafterlist{\@noparlisttrue}
\newcommand\noparafterlist{\@noparlistfalse}

The shortcut for a list in my editor yields e.g.

\begin{compactitem}

% \parafterlist % nur mit Skip
\end{compactitem}

If the use case occurs, and I agree it's common, I just uncomment the
penultimate line. It only works with skip, not with indented paragraphs.
\noparafterlist is in there for completeness' sake, I never ever used or
needed it.
