RubyVM::AbstractSyntaxTree.parse_file

RubyVM::AbstractSyntaxTree.parse_file(pathname) → RubyVM::AbstractSyntaxTree::Node

Reads the file from pathname, then parses it like ::parse, returning the root node of the abstract syntax tree.

SyntaxError is raised if pathname’s contents are not valid Ruby syntax.

Example
RubyVM::AbstractSyntaxTree.parse_file("my-app/app.rb")
# => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-31:3>
