Introduction
An application frequently needs data from a file that is logically part of the application; DataCompile allows such data to be bound into the program, and yet read as a PFS file.
Commands
DataCompileC outname { destination-directory | pattern }*
% DataCompileC myfiles.c /myfiles/ *.datafile /myfiles/more/ other/*.tip
% mako myfiles.c
% Run myfiles.o
% PMA /myfiles -compiled:/myfiles
This creates a c program that contains the contents of all the files named by the patterns, along with their new pathnames and their create dates. When the c program is compiled and run, it will register the files with CompiledViewImpl.
DataCompileMesa outname { destination-directory | pattern }*
% DataCompileMesa myfiles.mesa /myfiles/ *.datafile /myfiles/more/ other/*.tip
This creates a mesa program instead of a c program; you may want to do this because, for instance, it's simpler to bind it into a config. You may encounter a limit on the size of the file you can treat this way.
