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 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.
secNumber 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.
klassException Class to raise if the block fails to terminate in sec seconds. Omitting will use the default, Timeout::Error
messageError 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().
