Motivation
I posted about Writer gutter margin in general back in February, and two follow-up requests accumulated around this new feature since then.
First, the gutter margin could be on the left or at the top for non-mirrored documents, which initially sounded like a complete solution, but later it turned out that right-to-left (RTL) documents want it on the right.
Second, there was a request from the OASIS TC to to implement the ODF filter differently for gutter margin.
Neither of these is simple to do, so this hackweek was a good opportunity to address these problems.
Results so far
Here is the layout and user interface for RTL gutter looks like:
You can see how the gutter is on the right (not the left) and you can alter this behavior with a dedicated checkbox on the UI.
How is this implemented?

sw page rtl gutter margin: add doc model introduced a new RES_RTL_GUTTER page style property
-
sw page rtl gutter margin: add UNO API added a new public RtlGutter UNO API property

sw page rtl gutter margin: add ODF import mapped this to

sw page rtl gutter margin: add DOC filter mapped this to DOC’s SFRTLGutter, amusingly that handling of that was somewhat there, but more or less broken since 2002-02-04

\rtlguttersection flag -
sw page rtl gutter margin: add UI introduced a new checkbox on the UI to set/get this, and fixed up notifications, so that the incremental layout repaints the necessary page frames when this setting changes
Finally I had a little bit of remaining time, so I addressed a request from the OASIS ODF TC:
-
sw page gutter margin: reimplement ODF filter changed the ODF markup to be more compatible with readers ignoring
<style:page-layout-properties loext:margin-gutter="...">

Collabora intends to continue supporting and contributing to LibreOffice, the code is merged so we expect all of this work will be available in TDF’s next release (7.2).
