Compile a MatchLastLineNode
node
Dispatch enter and leave events for MatchLastLineNode
nodes and continue walking the tree.
Returns a relative path from the given base_directory
to the receiver.
If self
is absolute, then base_directory
must be absolute too.
If self
is relative, then base_directory
must be relative too.
This method doesn’t access the filesystem. It assumes no symlinks.
ArgumentError
is raised when it cannot find a relative path.
Note that this method does not handle situations where the case sensitivity of the filesystem in use differs from the operating system default.
Yields each frame of the current execution stack as a backtrace location object.
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.
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.
Main name of the switch.
Attach the list of comments to their respective locations in the tree.
