This method is called when a parse error is found.
ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str.
ERROR_VALUE is a value of error token.
value_stack is a stack of symbol values. DO NOT MODIFY this object.
This method raises ParseError by default.
If this method returns, parsers enter “error recovering mode”.
Returns the total bytes of the input data to the stream. FIXME
Returns the total bytes of the output data from the stream. FIXME
Same as IO.
Returns original filename recorded in the gzip file header, or nil if original filename is not present.
Specify the original name (str) in the gzip header.
Returns the major part of File_Stat#dev or nil.
File.stat("/dev/fd1").dev_major #=> 2 File.stat("/dev/tty").dev_major #=> 5
Returns the minor part of File_Stat#dev or nil.
File.stat("/dev/fd1").dev_minor #=> 1 File.stat("/dev/tty").dev_minor #=> 0
Returns the major part of File_Stat#rdev or nil.
File.stat("/dev/fd1").rdev_major #=> 2 File.stat("/dev/tty").rdev_major #=> 5
Returns the minor part of File_Stat#rdev or nil.
File.stat("/dev/fd1").rdev_minor #=> 1 File.stat("/dev/tty").rdev_minor #=> 0
Returns true if stat is writable by the real user id of this process.
File.stat("testfile").writable_real? #=> true
If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/tmp").world_writable? #=> 511 sprintf("%o", m) #=> "777"
Same as executable?, but tests using the real owner of the process.
Returns serialized iseq binary format data as a String object. A corresponding iseq object is created by RubyVM::InstructionSequence.load_from_binary() method.
String extra_data will be saved with binary data. You can access this data with RubyVM::InstructionSequence.load_from_binary_extra_data(binary).
Note that the translated binary data is not portable. You can not move this binary data to another machine. You can not use the binary data which is created by another version/another architecture of Ruby.
Returns the number of the first source line where the instruction sequence was loaded from.
For example, using irb:
iseq = RubyVM::InstructionSequence.compile('num = 1 + 2') #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> iseq.first_lineno #=> 1
Returns a Gem::StubSpecification for default gems
Return the latest specs, optionally including prerelease specs if prerelease is true.
Sanitize a single string.
Creates a duplicate spec without large blobs that aren’t used at runtime.
Returns an object you can use to sort specifications in sort_by.
Returns a Ruby code representation of this specification, such that it can be eval’ed and reconstruct the same specification later. Attributes that still have their default values are omitted.
Returns self
