Trying to use ntheorem's \theoremindent seems to indent the left side rather than the right side when used with polyglossia and right-to-left languages:



\setdefaultlanguage[calendar=hebrew, numerals=arabic]{hebrew}
\newfontfamily\hebrewfont{David CLM}

א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א א
ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב ב

enter image description here

Is this fixable?

Also it seems the numbering and separators are displayed wrong.

Note that the positioning of the colon (:) is also wrong: To the right, rather than the left, of the number. I guess ntheorem is very RTL-oriented in general... –  einpoklum Dec 12 '11 at 8:42
Have split-off the separator question to here. –  einpoklum Dec 12 '11 at 10:57

The offending lines in ntheorem-hyper.sty (or ntheorem.sty, depending on your distribution) seem to be:

\advance\@totalleftmargin \theorem@indent
\parshape \@ne \@totalleftmargin \linewidth

So, unsurprisingly, ntheorem assumes margins are on the left. Here's a suggested micro-patch, partially due to @egreg:


This should be adaptable into a patch for ntheorem-hyper.sty itself.

I could not post this as a comment so I had to post it as an answer. A modified version of Eyal/Egreg's patch is added to version 11.152 of bidi package which should be on CTAN soon. –  Simurgh12 Apr 16 '12 at 6:01
user13617 Have a look at the faq to know why you cannot comment yet. That's not a reason to use features with a different purpose instead. –  Stefan Kottwitz Apr 16 '12 at 7:19
