| Summary | 0000250: misplaced math (TLT) displays in TRT mode | ||||
| Description | From Vafa: The follwing tex file and its pdf output shows a bug which has not been fixed. It simply in RTL mode shifts display formula to the left instead placing it at the center. This has been tested with the luatex n TeXLive 2009. | ||||

This will take a while, this is a fairly tricky (because the outer text direction is hidden on the save stack when then shifts for the display box are calculated) |
|
|
Should be fixed by #2931 |
|
|
#2938 has a better fix (based on \pardir, not \textdir) |

This bug (or something close to it) resurfaced in 0.62.0. Vafa's test: \input bidi \pagedir TRT\pardir TRT\bodydir TRT\textdir TRT $$1+2=3\eqno(1)$$ \end |

I am pretty sure that this is a side effect of fixing \predisplaydirection primitive. Because as soon as you announced that \predisplaydirection is working, this bug again appeared. |
|
|
Taco, if it really related to \predisplaydirection fix, then I'd rather revert that fix; \predisplaydirection is a pretty obscure feature and having it broken for another release is better than breaking all TLT displays in TRT text (which is the most common RTL setup). |
|

Hi, I took a more serious approach and tried to fix the proplem properly without touching the \predisplaydirection stuff. The result is committed as #4170 in branches/0.70.x, and it appears to do the right thing in all cases now |
