.default_parser ⇒ Parser::Base

source://parser//lib/parser/base.rb#87

Returns:

# File 'sorbet/rbi/parser@3.3.8.0.rbi', line 807

def default_parser; end

.parse(string, file = T.unsafe(nil), line = T.unsafe(nil)) ⇒ Parser::AST::Node

Parses a string of Ruby code and returns the AST. If the source cannot be parsed, SyntaxError is raised and a diagnostic is printed to stderr.

source://parser//lib/parser/base.rb#33

Examples:

Parser::Base.parse('puts "hello"')

Parameters:

  • string (String) —

    The block of code to parse.

  • file (String) (defaults to: T.unsafe(nil)) —

    The name of the file the code originated from.

  • line (Numeric) (defaults to: T.unsafe(nil)) —

    The initial line number.

Returns:



822
 
# File 'sorbet/rbi/parser@3.3.8.0.rbi', line 822

def parse(string, file = T.unsafe(nil), line = T.unsafe(nil)); end

.parse_file(filename) ⇒ Parser::AST::Node

Parses Ruby source code by reading it from a file. If the source cannot be parsed, SyntaxError is raised and a diagnostic is printed to stderr.

source://parser//lib/parser/base.rb#67

Parameters:

  • filename (String) —

    Path to the file to parse.

Returns:

def parse_file(filename); end

.parse_file_with_comments(filename) ⇒ Array

Parses Ruby source code by reading it from a file and returns the AST and comments. If the source cannot be parsed, SyntaxError is raised and a diagnostic is printed to stderr.

source://parser//lib/parser/base.rb#80

Parameters:

  • filename (String) —

    Path to the file to parse.

Returns:

.parse_with_comments(string, file = T.unsafe(nil), line = T.unsafe(nil)) ⇒ Array

Parses a string of Ruby code and returns the AST and comments. If the source cannot be parsed, SyntaxError is raised and a diagnostic is printed to stderr.

source://parser//lib/parser/base.rb#52

Examples:

Parser::Base.parse_with_comments('puts "hello"')

Parameters:

  • string (String) —

    The block of code to parse.

  • file (String) (defaults to: T.unsafe(nil)) —

    The name of the file the code originated from.

  • line (Numeric) (defaults to: T.unsafe(nil)) —

    The initial line number.

def static_env; end

#tokenize(source_buffer, recover = T.unsafe(nil)) ⇒ Array

Parses a source buffer and returns the AST, the source code comments, and the tokens emitted by the lexer. In case of a fatal error, a SyntaxError is raised, unless recover is true. In case of an error (non-fatal or recovered), nil is returned instead of the AST, and comments as well as tokens are only returned up to the location of the error.

Currently, token stream format returned by #tokenize is not documented, but is considered part of a public API and only changed according to Semantic Versioning.

However, note that the exact token composition of various constructs might vary. For example, a string "foo" is represented equally well by :tSTRING_BEG " :tSTRING_CONTENT foo :tSTRING_END " and :tSTRING "foo"; such details must not be relied upon.

source://parser//lib/parser/base.rb#236

Parameters:

  • source_buffer (Parser::Source::Buffer)
  • recover (Boolean) (defaults to: T.unsafe(nil)) —

    If true, recover from syntax errors. False by default.

Returns:
