Returns a default parser

Compresses the given string. Valid values of level are Zlib::NO_COMPRESSION, Zlib::BEST_SPEED, Zlib::BEST_COMPRESSION, Zlib::DEFAULT_COMPRESSION, or an integer from 0 to 9.

This method is almost equivalent to the following code:

def deflate(string, level)
  z = Zlib::Deflate.new(level)
  dst = z.deflate(string, Zlib::FINISH)
  z.close
  dst
end

See also Zlib.inflate

Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.

This method is almost equivalent to the following code:

def inflate(string)
  zstream = Zlib::Inflate.new
  buf = zstream.inflate(string)
  zstream.finish
  zstream.close
  buf
end

Enables garbage collection, returning true if garbage collection was previously disabled.

GC.disable   #=> false
GC.enable    #=> true
GC.enable    #=> false

Returns a Hash containing information about the GC.

The contents of the hash are implementation-specific and may change in the future without notice.

The hash includes internal statistics about GC such as:

count

The total number of garbage collections run since application start (count includes both minor and major garbage collections)

time

The total time spent in garbage collections (in milliseconds)

heap_allocated_pages

The total number of :heap_eden_pages + :heap_tomb_pages

heap_sorted_length

The number of pages that can fit into the buffer that holds references to all pages

heap_allocatable_pages

The total number of pages the application could allocate without additional GC

heap_available_slots

The total number of slots in all :heap_allocated_pages

heap_live_slots

The total number of slots which contain live objects

heap_free_slots

The total number of slots which do not contain live objects

heap_final_slots

The total number of slots with pending finalizers to be run

heap_marked_slots

The total number of objects marked in the last GC

heap_eden_pages

The total number of pages which contain at least one live slot

heap_tomb_pages

The total number of pages which do not contain any live slots

total_allocated_pages

The cumulative number of pages allocated since application start

total_freed_pages

The cumulative number of pages freed since application start

total_allocated_objects

The cumulative number of objects allocated since application start

total_freed_objects

The cumulative number of objects freed since application start

malloc_increase_bytes

Amount of memory allocated on the heap for objects. Decreased by any GC

malloc_increase_bytes_limit

When :malloc_increase_bytes crosses this limit, GC is triggered

minor_gc_count

The total number of minor garbage collections run since process start

major_gc_count

The total number of major garbage collections run since process start

compact_count

The total number of compactions run since process start

read_barrier_faults

The total number of times the read barrier was triggered during compaction

total_moved_objects

The total number of objects compaction has moved

remembered_wb_unprotected_objects

The total number of objects without write barriers

remembered_wb_unprotected_objects_limit

When :remembered_wb_unprotected_objects crosses this limit, major GC is triggered

old_objects

Number of live, old objects which have survived at least 3 garbage collections

old_objects_limit

When :old_objects crosses this limit, major GC is triggered

oldmalloc_increase_bytes

Amount of memory allocated on the heap for objects. Decreased by major GC

oldmalloc_increase_bytes_limit

When :oldmalloc_increase_bytes crosses this limit, major GC is triggered

If the optional argument, hash, is given, it is overwritten and returned. This is intended to avoid the probe effect.

This method is only expected to work on CRuby.

The standard configuration object for gems.

Use the given configuration object (which implements the ConfigFile protocol) as the standard configuration object.

A Zlib::Deflate.deflate wrapper

Set array of platforms this RubyGems supports (primarily for testing).

Array of platforms this RubyGems supports.

Prints the amount of time the supplied block takes to run using the debug UI output.

Returns the currently set formatter. By default, it is set to DidYouMean::Formatter.

Updates the primary formatter used to format the suggestions.

Returns true if the file at path new is newer than all the files at paths in array old_list; false otherwise.

Argument new and the elements of old_list should be interpretable as paths:

FileUtils.uptodate?('Rakefile', ['Gemfile', 'README.md']) # => true
FileUtils.uptodate?('Gemfile', ['Rakefile', 'README.md']) # => false

A non-existent file is considered to be infinitely old.

Returns true if the file at path new is newer than all the files at paths in array old_list; false otherwise.

Argument new and the elements of old_list should be interpretable as paths:

FileUtils.uptodate?('Rakefile', ['Gemfile', 'README.md']) # => true

A non-existent file is considered to be infinitely old.

Set the default parser instance.

Returns a new URI object constructed from the given string uri:

URI.parse('https://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top')
# => #<URI::HTTPS https://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top>
URI.parse('http://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top')
# => #<URI::HTTP http://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top>

It’s recommended to first ::escape string uri if it may contain invalid URI characters.

Mirror the Prism.parse API by using the serialization API.

Compatibility methods for Ruby 3.2, we can remove this after dropping to support Ruby 3.2

Perform an operation in a block, raising an error if it takes longer than sec seconds to complete.

sec

Number of seconds to wait for the block to terminate. Any non-negative number or nil may be used, including Floats to specify fractional seconds. A value of 0 or nil will execute the block without any timeout. Any negative number will raise an ArgumentError.

klass

Exception Class to raise if the block fails to terminate in sec seconds. Omitting will use the default, Timeout::Error

message

Error message to raise with Exception Class. Omitting will use the default, “execution expired”

Returns the result of the block if the block completed before sec seconds, otherwise throws an exception, based on the value of klass.

The exception thrown to terminate the given block cannot be rescued inside the block unless klass is given explicitly. However, the block can use ensure to prevent the handling of the exception. For that reason, this method cannot be relied on to enforce timeouts for untrusted blocks.

If a scheduler is defined, it will be used to handle the timeout by invoking Scheduler#timeout_after.

Note that this is both a method of module Timeout, so you can include Timeout into your classes so they have a timeout method, as well as a module method, so you can call it directly as Timeout.timeout().
