Using methods from hash branches

[i-h8-github]

Is one supposed to redefine methods one wishes to use in each hash branch file instead of being able to use methods already defined in the main class file? Or am I doing something wrong?

#app.rb

class App < Roda
  ...
  route do |r|
    r.hash_branches ''
    ...
    r.is 'hello' do
      say_hello
    end
  end
  def say_hello
    puts 'hello'
  end
end

#routes/test.rb

class App
  hash_branch('test') do |r|
    ...
    r.is 'hello' do
      say_hello # undefined method `say_hello`
    end
  end
end

That approach should work. hash_branches doesn't change the class, it just dispatches to a new routing block in the same class. So as long as the class has a say_hello instance method defined, you can call it from any routing branch.

Try building a minimal app with the code you are showing to see that it works. If you have problems with a minimal app with just that code, please post the minimal app and I'll take a look.

A minimal app helped me determine that it was a scope issue. I'm definitely going to keep this minimal app around for helping verify these kinds of questions before asking here in the future.

Actually, on further testing, it seems to only go in one direction, i.e. if say_hello is defined in app.rb, routes.test.rb will be able to see it, but not vice versa.

# app.rb

require 'roda'

class App < Roda
  plugin :autoload_hash_branches
  autoload_hash_branch_dir('./routes')
  route do |r|
    r.hash_branches ''
    r.is 'hello' do
      say_hello
    end
  end
end

# routes/test.rb

class App
  hash_branch('test') do |r|
    # /test branch handling
    r.is 'hello' do
      say_hello
    end
  end
  def say_hello
    'hello'
  end
end

When you are autoloading branches, if the branch file hasn't been autoloaded, the method will not yet be defined. You should not define methods in a branch file that are called from other files when autoloading branches.
