Default spec directory path to be used if an alternate value is not specified in the environment
Return the value that should be dumped for the command_line option.
The iterator version of the strongly_connected_components
method. obj.each_strongly_connected_component
is similar to obj.strongly_connected_components.each
, but modification of obj during the iteration may lead to unexpected results.
each_strongly_connected_component
returns nil
.

The iterator version of the TSort.strongly_connected_components
method.
The graph is represented by each_node and each_child. each_node should have call
method which yields for each node in the graph. each_child should have call
method which takes a node argument and yields for each child node.

Creates a State
object from opts, which ought to be Hash
to create a new State
instance configured by opts, something else to create an unconfigured instance. If opts is a State
object, it is just returned.
This integer returns the maximum level of data structure nesting in the generated JSON
, max_nesting
= 0 if no maximum is checked.
This sets the maximum level of data structure nesting in the generated JSON
to the integer depth, max_nesting
= 0 if no maximum should be checked.
Returns true, if circular data structures should be checked, otherwise returns false.
This method is deprecated and should not be used. This is a no-op.
Sets the curve parameters. generator must be an instance of EC::Point
that is on the curve. order and cofactor are integers.
See the OpenSSL
documentation for EC_GROUP_set_generator()
Because we have mutated the AST to allow for newlines in the middle of a rational, we need to manually handle the value here.
Negate the value of a numeric node. This is a special case where you have a negative sign on one line and then a number on the next line. In normal Ruby, this will always be a method call. The parser gem, however, marks this as a numeric literal. We have to massage the tree here to get it into the correct form.

Within the given block, track that we’re within a pattern.

The current session cache mode.
Sets the SSL
session cache mode. Bitwise-or together the desired SESSION_CACHE_* constants to set. See SSL_CTX_set_session_cache_mode(3) for details.
Returns the current session cache size. Zero is used to represent an unlimited cache size.
