Thanks, this works for figures.

I couldn't get the same to work for chapters, sections, etc.

\setuphead[chapter,section][conversion=lefttorightnumber]

This does not have any effect.

The solution I had in the first email of this thread (see below) has another issue, which I discovered later.

\setuphead[chapter,title,section,subject][numbercommand=\righttoleft]

The 12th section in the first chapter is written as 1.12 instead of 12.1; I want the latter because of r2l align.

Another question: how do I change the separator to something else, say --?  I have played with separator and separatorset, but neither seems to work.

Hi,

Again this has been partly discussed on the list and solutions were already there but I didn't see anyone mention the issue with figures.

In the following MWE we have 20 pages of a simple text with a section, a footnote and a figure on each page.  The page numbers and footnote numbers are fine.  Section numbers need some care to appear correctly.  I couldn't figure out a similar mechanism for figure numbers, though.  The example does not use Indic numbers, which does not have any effect on the problem.

\setupdirections[bidi=global,method=two]
\setupalign[r2l]

%% If we don't provide the numbercommand, we'll see reverse numbering starting from 10.
\setuphead[chapter,title,section,subject][numbercommand=\righttoleft]
%% The following does not accept any numbercommand but it has numberconversion.
%% As a result figure numbers are shown in reverse.
\setupcaptions[numberstopper={:}]
%% Footnotes are fine and accept conversion.
%% Page numbers are also okay.

\starttext

\dorecurse{20}{

\section{Test}
This is a very simple text.
And we have a footnote\footnote{Footnote text}.

\placefigure
[][]
{Test figure.}
{\centerline{FIGURE BODY}}

\page
}

\stoptext

You can use processors.

\setupalign[righttoleft]

\defineprocessor [lefttoright][style=\lefttoright]
\defineconversionset[lefttorightnumber][][lefttoright->n]

\setupcaption[figure][numberconversionset=lefttorightnumber]

\starttext

\chapter{Chapter}

\dorecurse{20}{\placefigure{Dummy figure}{\blackrule[width=8cm,height=2cm]}}

\stoptext
