Ergonomic Arabic Keyboard layout. See website_ for details.

Creating layouts
----------------
Although optimized for the Arabic language it should be possible to create
layouts for other (non-RTL) languages as well. Here’s how to proceed: First,
create a data file ``my-layout.yaml`` that contains all key to character
mappings the new layout should have. Look at ``lulua/data/layouts`` for
examples. Then create statistics for a lzip-compressed corpus of your
choosing:
.. code:: bash
ls corpus/*.txt.lz | lulua-write text my-layout.yaml | lulua-stats combine > stats.pickle
Now you can optimize your layout using:
.. code:: bash
lulua-optimize -n 30000 --triad-limit=30000 -r -l my-layout.yaml < stats.pickle > evolved.yaml
To get a pretty picture (SVG) of your layout render it:
.. code:: bash
lulua-render -l evolved.yaml svg evolved.svg
It is highly recommended to use pypy3_ instead of CPython.

This software is using an extended version of carpalx_ by Martin Krzywinski for
optimizing layouts.
