Map from option/keyword string to object with completion.

Simple option list providing mapping from short and/or long option string to OptionParser::Switch and mapping from acceptable argument to matching pattern and converter pair. Also provides summary feature.

Hash with completion search feature. See OptionParser::Completion.

Raises when ambiguously completable string is encountered.

Raises when switch is undefined.

A compiler is a visitor that returns the value of each node as it visits. This is as opposed to a visitor which will only walk the tree. This can be useful when you are trying to compile a tree into a different format.

For example, to build a representation of the tree as s-expressions, you could write:

class SExpressions < Prism::Compiler
  def visit_arguments_node(node) = [:arguments, super]
  def visit_call_node(node) = [:call, super]
  def visit_integer_node(node) = [:integer]
  def visit_program_node(node) = [:program, super]
end

Prism.parse("1 + 2").value.accept(SExpressions.new)
# => [:program, [[[:call, [[:integer], [:arguments, [[:integer]]]]]]]]

DesugarCompiler is a compiler that desugars Ruby code into a more primitive form. This is useful for consumers that want to deal with fewer node types.

Represents an alternation pattern in pattern matching.

foo => bar | baz
       ^^^^^^^^^

Represents a regular expression literal that contains interpolation that is being used in the predicate of a conditional to implicitly match against the last line read by an IO object.

if /foo #{bar} baz/ then end
   ^^^^^^^^^^^^^^^^

Represents a string literal that contains interpolation.

"foo #{bar} baz"
^^^^^^^^^^^^^^^^

Represents an xstring literal that contains interpolation.

`foo #{bar} baz`
^^^^^^^^^^^^^^^^

Represents a regular expression literal used in the predicate of a conditional to implicitly match against the last line read by an IO object.

if /foo/i then end
   ^^^^^^

Represents an optional keyword parameter to a method, block, or lambda definition.

def a(b: 1)
      ^^^^
end

Represents an optional parameter to a method, block, or lambda definition.

def a(b = 1)
      ^^^^^
end

Represents a rational number literal.

1.0r
^^^^

Represents a singleton class declaration involving the ‘class` keyword.

class << self end
^^^^^^^^^^^^^^^^^

Represents the use of the ‘__ENCODING__` keyword.

__ENCODING__
^^^^^^^^^^^^

Represents a string literal, a string contained within a ‘%w` list, or plain string content within an interpolated string.

"foo"
^^^^^

%w[foo]
   ^^^

"foo #{bar} baz"
 ^^^^      ^^^^

Represents an xstring literal with no interpolation.

`foo`
^^^^^
