I originally tried to send this question on December 23, but the size of
the email was too large and the email bounced. So I have not included
the font. It bounced again several times because I was trying to include
the image inline. Attaching the image, the email was still too large. So
I will follow up with an email that contains the image. Sorry if this
question ends up appearing more than once.
_Problem:_
When using r2l alignment, layout of paragraphs appears to be flipped
(from r2l to l2r) after correctly placing the first paragraph inside of
a frame.
_Questions:_
1. What is going on? (I'm not sure how to describe what's happening.) Is
the paragraph not being formatted correctly or the frame?
2. What document can I look at to understand what's happening to format
the text? typo-duc.lmt seems to be referencing some other work that has
sections and tagged rules. What document is that?
3. What are typo-dir, typo-dha, and typo-duc each doing? I'm curious to
know so I can better navigate the codebase going forward.
I can reproduce the problem with the following minimal example
\defineparagraphs [Columns] [n=2,rule=on]
\starttext
\startframed[width=max,align=r2l]
\startColumns 1 \nextColumns 2 \stopColumns
\startColumns 1 \nextColumns 2 \stopColumns
\stopframed
\stoptext
The reason why the first environment is r2l is because it start in
horizontal mode while the second start in vertical mode, when you add
\dontleavehmode before the second one it will also switch to r2l.
One way to fix this problem is to add a direction key with will by
default place the column "left to right" with the option to reverse it
to "right to left".
