gemspec_deps_gen

gem for generating project dependencies inside gemspec file

Installation

Add this line to to your Gemfile:

gem "gemspec_deps_gen"

And then execute:

$ bundle

Usage

Create .gemspec.erb file:

Gem::Specification.new do |spec|
  spec.name = "sample"
  spec.summary = %q{Summary.}
  spec.description = %q{Description.}
  spec.email = "[email protected]"
  spec.authors = ["Alexander Shvets"]
  spec.homepage = "http://github.com/shvets/sample"

  spec.files = `git ls-files`.split($\)
  spec.test_files = spec.files.grep(%r{^(test|spec|features)/})

  spec.version = "1.0.0"

  <%= project_dependencies %>
end

You can see ERB fragment (project_dependencies) included inside the body of the specification.

Now, run this command:

$ gemspec_deps_gen <project_name>

It will generate .gemspec and replace ERB fragment with dependencies from Gemfile:

Gem::Specification.new do |spec|
  ...

  spec.add_runtime_dependency "bundler", [">= 0"]
  spec.add_runtime_dependency "file_utils", [">= 0"]
  spec.add_development_dependency "gemcutter", [">= 0"]

end

As alternative, you can call it as rake command:

require "gemspec_deps_gen"

project_name = <your project name>

task :gen do
  generator = GemspecDepsGen.new project_name

  generator.generate_dependencies "spec", "#{project_name}.gemspec.erb", "#{project_name}.gemspec"
end

$ rake gen
