\begin{frame}[fragile]
\frametitle{Introduction}
Creating beamer presentation for  right to left language  (like arabic) using \hologo{pdfLaTeX} or \hologo{XeLaTeX} still poses many problems due to bugs not currently resolved especially for colors and hyperlinks

The \hologo{LuaTeX} team set solutions for  these issues thanks to them and to \textit{Javier~Bezos} for  his works on the package \verb|babel| and \verb|bidi| writing    

This class provides patchs of some beamer templates and commands 
for right to left presentation, this package call babel with \verb|bidi=basic-r| option and require lualatex engine

\framesubtitle{The proof uses \textit{reductio ad absurdum}.}
\begin{theorem}
There is no largest prime number.
\end{theorem}
\begin{proof}
\begin{enumerate}[<+-| alert@+>]
\item Suppose $p$ were the largest prime number.
\item Let $q$ be the product of the first $p$ numbers.
\item Then $q+1$ is not divisible by any of them.
\item But $q + 1$ is greater than $1$, thus divisible by some prime
number not in the first $p$ numbers.\qedhere

\begin{itemize}

\item

All options provided by \verb:beamer:  can be added  with  \verb:beamer-rl:

Additional options can also be passed to  package 
 \verb:babel: 
 with  \verb:beamer-rl: like this

\medskip 
 
{\selectlanguage{nil}
\verb:\documentclass[babel={<babel options>}]{beamer-rl}:
}

\medskip

\item
The \verb:beamer-rl: class swap the definition of \verb:\blacktriangleright: with  \verb:\blacktriangleleft: in RTL context

\bigskip

{\renewcommand{\arraystretch}{1.3}
\centering
\begin{tabular}{ccc}
\hline
 &  \verb:\blacktriangleright: & \verb:\blacktriangleleft:   \\
\hline 
LTR context & \blacktriangleright & \blacktriangleleft \\
\hline
RTL context & \selectlanguage{nil}\blacktriangleright & \selectlanguage{nil}\blacktriangleleft \\
\hline
\end{tabular}
\par
}

\bigskip


\item

Class option \verb:arabic: call an Arabic dictionary to translate strings like \verb:theorem:, \verb:example:, \verb:definition: ....  


\medskip 
 
{\selectlanguage{nil}
\verb:\documentclass[arabic]{beamer-rl}:
}

\medskip


\item
In some cases you  need to use \verb:\babelsublr: command from \verb:bebel: 
package to insert a left to right text within your right to left text, e.g if you need to insert a \verb:pspicture: drawing in RTL context 

\medskip 
 
{\selectlanguage{nil}
\verb:\bebelsublr{LTR context ... }:
}
