خطای ! Undefined control sequence.

پس از نصب livetex 2015 متوجه شدم خیلی از sample ها اجرا نمیشن و خطای

! Undefined control sequence.

رو میدن

اینم راه حل:

\usepackage[localise=on]{xepersian}

XePersian stopped working after texlive-bin updated

Today an update for the package "texlive-bin" was issued by Arch Repository, and I think it was after I installed that update that my XePersian package broke. Now, I get a weird error when I try to compile the following simple document:

\documentclass{article}

\usepackage{xepersian}
\settextfont{XB Niloofar}

\شروع{نوشتار}
سلام این یک آزمون است.
\پایان{نوشتار}

which is basically the same as the following, but with XePersian aliases:

\documentclass{article}

\usepackage{xepersian}
\settextfont{XB Niloofar}

\begin{document}
hello this is a test.
\end{document}

The error says:

! Undefined control sequence.
l.6 \شروع
             {نوشتار}

And here is the log file generated by xelatex. The second example compiles just fine; but the first one, to which the enclosed log file belongs, is giving me troubles.

I suspect the problem is caused by some version inconsistency due to the update. But I can't find a way to get around that. I even tried downgrading "texlive-bin", which I suspected to be guilty for the inconsistency, but the problem persisted. No, I did not forget to run texhash afterwards.

Any ideas?

I added an option [localise=on] to my usepackage, like:

\usepackage[localise=on]{xepersian}

and it works now. I guess the new version requires it.
