<div dir="ltr">Hi Jonathan<br><br>Do you have any plan of integrating omega bidirectional primitives into XeTeX or perhaps adding more primitives for RTL typesetting. I personally like TeX--XeT bidirectional primitives over omega because I believe it is more stable than omega's bidirectional primitives but if we could fix issues with color and hyperref, then the issue of color and hyperref would be fixed. I looked at TeX-e-Parsi's source code and I can send you the web source code if you want. What they have done is they implemnted two new primitives \beginspecial and \endspecial and they put special materials between these two primitives and color works nice in TeX-e-Parsi without any issue.<br>
<br>Also if you could add a new primitive \semihalign which I talked to you later, would be really great. This primitive also exists in TeX-e-Parsi source code and I guess it would not be too difficult for you to take the codeĀ from TeX-e-parsi and apply that code to XeTeX or perhaps you could use omega bidirectional primitives instead this.<br>
<br>What do you think?<br><br>I tried several times to add these two primitives from TeX-e-Parsi source code into XeTeX but when I compiled, it just simply failed.<br></div>
