How to change arabic text alignment with polyglossia and memoir?

Question

I am trying to typeset a book which is completely in arabic. I am using memoir with polyglossia?

The result is fine, but the text is Fully Justified ?

How can i change the text alignment either through polyglossia, memoir or plain latex ?

Answer 1

I reach for the ragged2e package when adjusting text alignment. While not all of its advantages are applicable to Arabic, it gets the job done.

In your preamble:

\usepackage{ragged2e}
\RaggedLeft

You can change the indentation of the ragged left paragraphs with:

\setlength\RaggedLeftParindent{1.25em}
