[***SPAM***] Two-language environment and page breaking

[***SPAM***] Two-language environment and page breaking

["H. Özoguz"]

Hi,

one more question to my arabic-german table environment. See this code:

\definefont[amiri][file:UthmanTN1Ver10.ttf*arabic at 11 pt] % or 
amiri-regular.ttf
\define[1]\Arab{\setupalign[r2l]\amiri#1}
%\showgrid
\startsetups[arde]
\setupTABLE[c][1][rightframe=on]
\stopsetups
\def\startarde
{\bTABLE[frame=off,width=.5\textwidth,setups=arde,split=yes]}
\def\stoparde
{\eTABLE}
\define[2]\arde
{\bTR
\bTD [align={tolerant, stretch}, 
roffset=1ex,style={\setupinterlinespace[line=3ex]}] #1\eTD
\bTD[align={r2l,tolerant,stretch}, 
loffset=1ex,style={\amiri\setupinterlinespace[line=5.4ex]}] #2 \eTD
\eTR}
\starttext
\startarde
\arde{%
Dies ist nur ein vollkommen sinnfreier Text und hat rein gar nichts mit 
dem Arabischen auf der rechten Seiten zutun. Wirklich gar nichts. 
Glauben Sie es mir? Also versuchen Sie nicht den Sinn des Arabischen 
hierdurch zu erfassen.
}
{%
اللهُمَّ ارْزُقْنِي حَجَّ بَيْتِك الحَرامِ فِي عامِي هذا وَفِي كُلِّ عامٍ ما أَبْقَيْتَنِي فِي يُسْرٍ مِنْكَ 
وَعافِيَةٍ وَسَعَةِ رِزْقِ، وَلا تُخْلِنِي

}
\stoparde
\blank
{\bf Should be the same like:}\blank
\startarde
\arde{%

الدُّنْيا وَالآخرةِ فَكُنْ }
\stoparde
\stoptext

In the code you see two \startarde\stoparde blocks. The first block is 
the example, the correct setting. But the first block can not be broken 
over pages. This is fixed by the second block, where I seperated the 
text into two "\arde", so now it can be broken over pages, because they 
are now two different tables. But if they are NOT broken over pages, 
they sould be set as if they were only one table, so as in the first 
"\startarde\stoparde" block. But the are not. You see the small distance 
between them.

Is there a way to produce the behavior I descibed? It would be a 
workaround to get natural tables, which can be broken over pages (my 
manually sperating them). (Only natural tables are possible for this 
environment, and not normales tables, because of the needed different 
interlinespace of the two columns).

Thanks.
Huseyin

Hi,

I don't know a real solution, just 2 workarounds:

1.) A \vskip-3pt between the 2 paragraphs.

2.) My cld-hack, as shown in the 2 attached files.
