I am trying to typeset a two-column text in a right-to-left language
using ConTeXt. Because I want footnotes in this text to be set
ragged-bottom, I am using pagecolumns instead of standard columns. I
also want to track the first and last textual division markers on each
page using markings. Combining all of these ingredients seems to create
a problem in ConTeXt: when the pagecolumns are set in right-to-left
order, the top and bottom marks fetched are always the top and bottom
marks in the left column, while the true top mark should be the top mark
of the right column. I've observed this behavior using text in an actual
right-to-left language, but the following minimal (non-)working example
with an English sample text demonstrates the same behavior:
```
%Create a new markset to use:
\definemarking[TestMark]
%Setup header to reflect top and bottom marks:
\setupheadertexts[top: {\fetchmark[TestMark][top]}][bottom:
{\fetchmark[TestMark][bottom]}][top:
{\fetchmark[TestMark][top]}][bottom: {\fetchmark[TestMark][bottom]}]
%even left, even right, odd left, odd right
%Setup the columns layout:
\definepagecolumns [example] [
n=2, %number of columns
direction=reverse, %does not work if ending comma is removed!
]
\starttext
\startpagecolumns[example]
\marking[TestMark]{1}(1) \input knuth\par
\marking[TestMark]{2}(2) \input knuth\par
\marking[TestMark]{3}(3) \input knuth\par
\marking[TestMark]{4}(4) \input knuth\par
\marking[TestMark]{5}(5) \input knuth\par
\marking[TestMark]{6}(6) \input knuth\par
\marking[TestMark]{7}(7) \input knuth\par
\marking[TestMark]{8}(8) \input knuth\par
\stoppagecolumns
\stoptext
```
I typeset this using ConTeXt version 2020.03.10, as released with
TeXLive 2020. As my comment in the MWE points out, there also seems to
be a bug in the key-value parsing of \definepagecolumns that causes it
not to parse the direction=reverse input unless it is followed by a comma.
Is there some way I can improve my syntax to avoid this issue, or is it
just a bug that needs to be fixed? I've tried fetching other marks
(e.g., first and last), but the only marks that ConTeXt seems to find
are the ones for the left column.
what if you prefix with column:, like column:top and so
