[NTG-context] More about that footnote problem...

[ishamid]

Dear crew,

Here is a concrete example that illustrates the footnote problem. As usual, 
just compile a ConTeXt format under eomega:

===============mix-dir-foot.tex===========
\input m-gamma.tex
\input type-omg.tex

\setupbodyfont[omlgc,12pt]

\starttext

\dorecurse{5}{\input knuth\footnote{test}\par}

\startarab

\dorecurse{3}{hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA
'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN
hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA
'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN
hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA
'iimtiHAnuN\footnote{hAdhA 'iimtiHAnuN}\par}

\blank[big]

\dorecurse{3}{hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA

'iimtiHAnuN%
\footnote{%
\startarab %
hAdhA 'iimtiHAnuN %
\stoparab}
\par}

\blank[big]

\setupfootnotes[numbercommand={\switchtobodyfont[omarb]}]

\dorecurse{3}{hAdhA 'iimtiHAnuN hAdhA 'iimtiHAnuN hAdhA

\footnote{%

\stoparab}
\par}

\stoparab

\stoptext
==========================================

Again, the document is globally left-to-right, but for right-to-left documents 
I want the footnote markers in the right margin, and the rule flush right as 
well. The relative local eomega direction commands are

\textdir TLT (LR text)
\pardir TLT (LR paragraphs)
\textdir TRT (RL text)
\pardir TRT (RL paragraphs)

though they are not really needed to create parameter options that give me 
what I want. I played around with some of the macros in core-not.tex but that 
stuff is way over my ahead and I could not make any progress:-(

NOTE: in the second set of RL footnotes, note that the footnote markers get 
pushed into the textblock. In the third set of RL fotnotes, we get Arabic 
markers using

\setupfootnotes[numbercommand={\switchtobodyfont[omarab]}]

but then we lose the default

\setupfootnotes[numbercommand=\high]

and the Arabic-script numerals are again pushed into the textblock.

I look forward to your suggestions

Best
