def self.parse_file pathname, keep_script_lines: RubyVM.keep_script_lines, error_tolerant: false, keep_tokens: false
Primitive.ast_s_parse_file pathname, keep_script_lines, error_tolerant, keep_tokens
end
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>
See ::parse for explanation of keyword argument meaning and usage.
