Handle BasicObject instances

Set local variable named symbol as obj.

def foo
  a = 1
  bind = binding
  bind.local_variable_set(:a, 2) # set existing local variable `a'
  bind.local_variable_set(:b, 3) # create new local variable `b'
                                 # `b' exists only in binding

  p bind.local_variable_get(:a)  #=> 2
  p bind.local_variable_get(:b)  #=> 3
  p a                            #=> 2
  p b                            #=> NameError
end

This method behaves similarly to the following code:

binding.eval("#{symbol} = #{obj}")

if obj can be dumped in Ruby code.

Sets a thread local with key to value. Note that these are local to threads, and not to fibers. Please see Thread#thread_variable_get and Thread#[] for more information.

Attempts to enter exclusive section. Returns false if lock fails.

For backward compatibility

MRI specific feature

Return internal super class of cls (Class or Module).

obj can be an instance of InternalObjectWrapper.

Note that you should not use this method in your application.

The number of paths in the ‘$LOAD_PATH` from activated gems. Used to prioritize `-I` and `ENV` entries during `require`.

The default signing certificate chain path

Like Enumerable#select, but chains operation to be lazy-evaluated.

Emit a scalar with value and tag

Emit a sequence with list and tag

Called when a sequence is started.

anchor is the anchor associated with the sequence or nil. tag is the tag associated with the sequence or nil. implicit a boolean indicating whether or not the sequence was implicitly started. style is an integer indicating the list style.

See the constants in Psych::Nodes::Sequence for the possible values of style.

Example

Here is a YAML document that exercises most of the possible ways this method can be called:

---
- !!seq [
  a
]
- &pewpew
  - b

The above YAML document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:

# anchor    tag                       implicit  style
[nil,       nil,                      true,     1     ]
[nil,       "tag:yaml.org,2002:seq",  false,    2     ]
["pewpew",  nil,                      true,     1     ]

Start emitting a sequence with anchor, a tag, implicit sequence start and end, along with style.

See Psych::Handler#start_sequence

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”.
