beameripad
I'm considering buying one of the available LaTeX apps for my iPad. Among other things, one of the main things I'm interested in is tweaking my beamer presentations (particularly handy when on the go).
Does anyone if there's an app that can compile beamer locally, i.e. without connecting to some server as is the case for some? I'm not always guaranteed an Internet connection when traveling/commuting.
As far as I'm aware you can't install LaTeX on the iPad because of the restrictions that Apple put on it. However, tex documents can be edited and compiled using Tex Touch . The editor is installed on the iPad and the tex document is then compiled online at TeX Cloud. I haven't used Tex Touch myself so I can't comment on how well it works.
Here's a simple approach using the \@starttoc command through the newly defined \listofframes command; the new list will have extension .lbf. \addtobeamertemplate was used so that the frametitle command writes the desired information (frame number and title) to the .lbf file. The list is created issuing \listofframes:
\documentclass{beamer}
\makeatletter
\newcommand\listofframes{\@starttoc{lbf}}
\makeatother
\addtobeamertemplate{frametitle}{}{%
\addcontentsline{lbf}{section}{\protect\makebox[2em][l]{%
\protect\usebeamercolor[fg]{structure}\insertframenumber\hfill}%
\insertframetitle\par}%
}
\begin{document}
\begin{frame}
\frametitle{List of Frames}
\listofframes
\end{frame}
\begin{frame}
\frametitle{Test Frame One}
test
\end{frame}
\begin{frame}
\frametitle{Test Frame Two}
test
\end{frame}
\end{document}
Here's the resulting List of Frames:
To facilitate control over which frames to include in the new list, you can use a boolean switch; in the following example I used \ifframeinlbf initially set to true; if you want to suppress some titled frame(s) from the list of frames, use \frameinlbffalse right before those frame(s) and then use \frameinlbftrue right after the frame(s) to activate inclusion in the list:
\documentclass{beamer}
\newif\ifframeinlbf
\frameinlbftrue
\makeatletter
\newcommand\listofframes{\@starttoc{lbf}}
\makeatother
\addtobeamertemplate{frametitle}{}{%
\ifframeinlbf
\addcontentsline{lbf}{section}{\protect\makebox[2em][l]{%
\protect\usebeamercolor[fg]{structure}\insertframenumber\hfill}%
\insertframetitle\par}%
\else\fi
}
\begin{document}
\frameinlbffalse
\begin{frame}
\frametitle{List of Frames}
\listofframes
\end{frame}
\frameinlbftrue
\begin{frame}
\frametitle{Test Frame One}
test
\end{frame}
\begin{frame}
\frametitle{Test Frame Two}
test
\end{frame}
\end{document}

Texpad developers here.
We added support for Beamer and Tikz in v1.5.0 and now the majority of beamer presentations and tikz diagrams typeset with Texpad on iOS. @AndrewStacey is correct that Texpad's internal TeX will occasionally run out of memory when typesetting large presentations, but we are working on this, and we expect it to be fixed in one of the early 1.5.x updates.
