Returns the class for the given object.
class A def foo ObjectSpace::trace_object_allocations do obj = Object.new p "#{ObjectSpace::allocation_class_path(obj)}" end end end A.new.foo #=> "Class"
See ::trace_object_allocations for more information and examples.
Returns the size of memory allocated by malloc().
Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.
The number of paths in the +$LOAD_PATH+ from activated gems. Used to prioritize -I and ENV['RUBYLIB'] entries during require.
Returns the value of Gem.source_date_epoch_string, as a Time object.
This is used throughout RubyGems for enabling reproducible builds.
Deduce Ruby’s –program-prefix and –program-suffix from its install name
Should be implemented by a extended class.
tsort_each_child is used to iterate for child nodes of node.
case foo; in bar; end ^^^^^^^^^^^^^^^^^^^^^
foo => bar ^^^^^^^^^^
/(?<foo>foo)/ =~ bar ^^^^^^^^^^^^^^^^^^^^
if /foo #{bar}/ then end
^^^^^^^^^^^^
Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x returned by block is decomposed if either of the following conditions is true:
x responds to both each and force, which means that x is a lazy enumerator.
x is an array or responds to to_ary.
Otherwise, x is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]
See Zlib::GzipReader documentation for a description.
Iterate all direct child instruction sequences. Iteration order is implementation/version defined so that people should not rely on the order.
Attach the list of comments to their respective locations in the tree.
Defaults to use Ruby’s program prefix and suffix.
