Linebreaks after items with overlay specifications of beamer

[nils-schween]

Hi and thanks for developing latex indent,

I am currently creating a beamer presentation and I noticed that there are no line breaks after items in an itemize environment with overlay specifications.

original .tex code

  \begin{itemize}
    \item<1-> The acceleration and the transport of charged particles (Cosmic rays) is modelled with
      the \enquote{transport equation}.
    \item<2-> The transport equation is a Vlasov-Fokker-Planck (VFP) equation combined with the
      diffusion approximation, i.e. an almost isotropic distribution function.
    \item<3-> Anisotropies play an important role in, for example, the feedback of
      charged particles onto the accelerating plasma.
    \item<4-> We have two aims:
      \begin{enumerate}
        \item<6-> \textbf<8->{leaving the diffusion approximation behind} and
        \item<7-> computing the feedback of the Cosmic rays.
      \end{enumerate}
  \end{itemize}

My current yaml settings are

defaultIndent: "  "
lookForAlignDelims:
  split: 1
modifyLineBreaks:
  textWrapOptions:
    columns: 20

The ouput of latexinden is

\begin{frame}
  \frametitle{Modelling the acceleration process of Cosmic Rays}
  \begin{itemize}
    \item<1-> The acceleration and the transport of charged particles (Cosmic rays) is modelled with
      the \enquote{transport equation}.
    \item<2-> The transport equation is a Vlasov-Fokker-Planck (VFP) equation combined with the
      diffusion approximation, i.e. an almost isotropic distribution function.
    \item<3-> Anisotropies play an important role in, for example, the feedback of
      charged particles onto the accelerating plasma.
    \item<4-> We have two aims:
      \begin{enumerate}
        \item<6-> \textbf<8->{leaving the diffusion approximation behind} and
        \item<7-> computing the feedback of the Cosmic rays.
      \end{enumerate}
  \end{itemize}

If I remove the overlay specifiactions, I get

  \begin{itemize}
    \item The acceleration
          and the transport
          of charged
          particles (Cosmic
          rays) is modelled
          with the
          \enquote{transport
            equation}.
    \item The transport
          equation is a
          Vlasov-Fokker-Planck
          (VFP) equation
          combined with the
          diffusion
          approximation, i.e.
          an almost isotropic
          distribution
          function.
    \item Anisotropies play
          an important role
          in, for example,
          the feedback of
          charged particles
          onto the
          accelerating
          plasma.
    \item We have two aims:
          \begin{enumerate}
            \item \textbf{leaving the diffusion approximation behind} and
            \item computing the
                  feedback of the
                  Cosmic rays.
          \end{enumerate}
  \end{itemize}

I would expect something similar for the items with overlay specifications. My latexindent version is 3.20.3

It tried the manipulate the blockFollows: other: field, but I was not able to construct a regex which includes the overlays. Thanks for your help. Nils

Thanks for this.

Can you try

blocksFollow:
           other: \\\]|\\item(?:\h|\[|<[^>]+?)

Thanks, for your quick reply. I just tested it. It unfortunately does not work. I attach my indent.log file.

I am really sorry. It does work. I do not know what I did wrong yesterday. Thank you very much!
