DSL has no methods

Which version of prism are you using? I get:

irb(main):007> (Prism::DSL.methods - Module.methods).length
=> 167

I can reproduce the error on 0.30.0:

irb(main):001> require "prism"
=> true
irb(main):002> puts Prism::VERSION
0.30.0
irb(main):003>  (Prism::DSL.methods - Module.methods).length
=> 0

# ...

irb(main):029> Builder.new.build
(irb):10:in `initialize': undefined method `source' for an instance of Builder (NoMethodError)

    @default_source = source("[1]")
                      ^^^^^^

Thanks for the quick response.

Which version of prism are you using?

0.30.0

Looking at the lib/prism/dsl.rb file of my prism gem on version 0.30.0 it shows that it has the old version of the DSL code with the PascalCased methods. Maybe the 0.30.0 version of the gem was published without compiling the dsl.rb.erb file again?

Here's a snippet:

# ~/.anyenv/envs/rbenv/versions/3.3.4/lib/ruby/gems/3.3.0/gems/prism-0.30.0/lib/prism/dsl.rb

module Prism
  # ...

  module DSL
    private

    # Create a new Location object
    def Location(source = nil, start_offset = 0, length = 0)
      Location.new(source, start_offset, length) # steep:ignore
    end

    # Create a new AliasGlobalVariableNode node
    def AliasGlobalVariableNode(new_name, old_name, keyword_loc, source = nil, location = Location())
      AliasGlobalVariableNode.new(source, new_name, old_name, keyword_loc, location)
    end
  
  # ...
end

Ahh shoot sorry that documentation reflects main, which hasn't been released yet. That'll be out soon.

[kddnewton]

In the meantime you're welcome to point to main (to use the new APIs) or you can use the old APIs (the documentation that ships with the gem).

Gotcha, thanks so much!
