This is a program to generate a Lojban/English dictionary for the macOS Dictionary.app based on the lojban.org official word lists.
To build the dictionary, you need to get the Dictionary Development Kit.
You can find it at https://developer.apple.com/download/more/, under the name "Auxiliary Tools for Xcode 7."
Then you should set the DICT_BUILD_TOOL_DIR
variable in the makefile to the location where you installed it.
In order to build the content of the dictionary, use
make all
To copy the dictionary into the proper location, use
make install
The dictionary will not reload if Dictionary.app is still open, so close it before running make install. My preferred workflow is to run
make all && make install && open /Applications/Dictionary.app
and then close Dictionary.app while the dictionary compile is running.
