Instance Method Summary

• #s(*args) ⇒ Object

  Builds and s-expression by creating AstNode objects with the type provided by the first argument.

Instance Method Details

#s(*nodes, opts = {}) ⇒ AstNode #s(type, *children, opts = {}) ⇒ AstNode

Builds and s-expression by creating AstNode objects with the type provided by the first argument.

Examples:

An implicit list of keywords

ast = s(s(:kw, "if"), s(:kw, "else"))
ast.type # => :list

A method call

s(:command, s(:var_ref, "mymethod"))

Overloads:

• #s(*nodes, opts = {}) ⇒ AstNode

  Returns an implicit node where node.type == :list.

  Parameters:

  • nodes (Array<AstNode>) —

    a list of nodes.

  • opts (Hash) (defaults to: {}) —

    any extra options (docstring, file, source) to set on the object

  Returns:

  • (AstNode) —

    an implicit node where node.type == :list

• #s(type, *children, opts = {}) ⇒ AstNode

  Returns a node of type type.

  Parameters:

  • type (Symbol) —

    the node type

  • children (Array<AstNode>) —

    any child nodes inside this one

  • opts (Hash) (defaults to: {}) —

    any extra options to set on the object

  Returns:

  • (AstNode) —

    a node of type type.
