Graaf

Ruby FFI for Built a Shared Library by GraalVM Native Image

Using a Shared Library built with GraalVM Native Image requires built-in control over IsolateThread.

This gem manages the control of IsolateThread.

Install the gem and add to the application's Gemfile by executing:

$ bundle add graaf

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install graaf

module Example
  extend Graaf::Library

  graaf_lib('libexample.so')

  # @note
  #   The first argument `graal_isolatethread_t*` does not need to be specified.
  graaf_attach_function :add, [:int, :int], :int
end

Example.add(1, 2)
# => 3
