@ -19,15 +19,26 @@ Build from git repo:
$ git clone git://github.com/ueno/eekboard.git
$ cd eekboard
$ ./autogen.sh --prefix=/usr --enable-gtk-doc
Build from tarball:
$ ./configure
$ make
$ sudo make install
$ eekboard
How to test (dump/load the current layout):
$ ./tests/eek-example-xml -d > keyboard.xml
$ ./tests/eek-example-xml -l keyboard.xml
NOTE: eekboard is now being heavily rewritten and it may behave
wrongly. Make sure to close windows where you are doing any important
work, before running eekboard.
$ ./src/eekboard-server &
$ ./src/eekboard-system-client --xklavier --accessibility --fakekey
Where --xklavier is to monitor system keyboard layout change,
--accessibility is to track focus/key events via AT-SPI, and --fakekey
generates X key events when eekboard-server signals virtual
key-press/key-release events.
