A Ruby interface / front-end to the reggae meta-build system.
gem install reggae
The reason for a global install is that the
reggae gem installs an executable script
reggae_json_build.rb that is needed by the
reggae D binary.
This gem makes available a few classes and functions that allow the user to write build descriptions in Ruby. It is essentially the same API as the D version but in Ruby syntax. A simple C build could be written like this:
require 'reggae' main_obj = Target.new('main.o', 'gcc -I$project/src -c $in -o $out', Target.new('src/main.c')) maths_obj = Target.new('maths.o', 'gcc -c $in -o $out', Target.new('src/maths.c')) app = Target.new('myapp', 'gcc -o $out $in', [main_obj, maths_obj]) bld = Build.new(app)
This should be contained in a file named
reggaefile.rb in the project's root directory.
reggae D binary on that directory will produce a build with the requested backend
(ninja, make, etc.)
Most builds will probably not resort to low-level primitives as above. A better way to describe that C build would be:
require 'reggae' objs = object_files(flags: '-I$project/src', src_dirs: ['src']) app = link(exe_name='app', dependencies=objs) bld = Build.new(app)
Please consult the reggae documentation for more details.
