Some kobo touch devices have X Y coordinates in touch events swapped.
This patch provides a GUI to probe if the device needs to swap the XY.
The Kobo Touch users will be directed to tap on the upper right corner
of the screen and the probe will check if the X value is smaller than
the Y value in the tap event.
Currently only tested on Ubuntu-touch emulator with framework
ubuntu-sdk-14.10 for armhf.
The ubuntu-touch port is binary compatible with the Kobo port
major changes in this PR are:
1. rename the emulator device to sdl device since both the emulator
and the ubuntu-touch target use libsdl to handle input/output.
2. ubuntu-touch app has no write access to the installation dir so
all write-outs should be in a seperate dir definded in `datastorage`.
The new container-based format doesn't do sudo anymore, so there are some extensive changes.
It does, however, allow cache.
I also took the opportunity to switch to a newer busted. The root element for that now needs to be a table.
On kindle, kobo and pocketbook the data directory is the current
running directory but on Android the app is installed in system
defined location and users may have no access to that location.
The same circumstances should be true for the upcoming Koreader for
Ubuntu touch, so the data directory (in which tessdata, dictionaries,
global settings, persistant defaults and probably history data are
stored) could be stored in another place.
since users may have mantained their own extensions.cfg file
The extensions.cfg file is still in the release package and users
could manually copy the `system` directory to the USB root if they
want Koreader to handle all their documents.
so that we can easily find which module needs unit test
In order to run 'make coverage' `luacov` need to be installed
with 'sudo luarocks install luacov'.
aternatively the resource file(pot file) in Transifex is updated
with `make pot` and the translated files(po files) is updated with
`make po`. `make pot po` will be handled automatically on the nightly
build machine.
