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

Returns true if the named file is readable by the effective user and group id of this process. See eaccess(3).

Note that some OS-level security features may cause this to return true even though the file is not readable by the effective user/group.

Returns true if the named file is writable by the effective user and group id of this process. See eaccess(3).

Note that some OS-level security features may cause this to return true even though the file is not writable by the effective user/group.

Returns true if the named file is executable by the effective user and group id of this process. See eaccess(3).

Windows does not support execute permissions separately from read permissions. On Windows, a file is only considered executable if it ends in .bat, .cmd, .com, or .exe.

Note that some OS-level security features may cause this to return true even though the file is not executable by the effective user/group.

Initiates garbage collection, even if manually disabled.

This method is defined with keyword arguments that default to true:

def GC.start(full_mark: true, immediate_sweep: true); end

Use full_mark: false to perform a minor GC. Use immediate_sweep: false to defer sweeping (use lazy sweep).

Note: These keyword arguments are implementation and version dependent. They are not guaranteed to be future-compatible, and may be ignored if the underlying implementation does not support them.

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

Retrieve the PathSupport object that RubyGems uses to lookup files.

Initialize the filesystem paths to use from env. env is a hash-like object (typically ENV) that is queried for ‘GEM_HOME’, ‘GEM_PATH’, and ‘GEM_SPEC_CACHE’ Keys for the env hash should be Strings, and values of the hash should be Strings or nil.

A Zlib::Inflate#inflate wrapper

Top level install helper method. Allows you to install gems interactively:

% irb
>> Gem.install "minitest"
Fetching: minitest-3.0.1.gem (100%)
=> [#<Gem::Specification:0x1013b4528 @name="minitest", ...>]

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

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

Updates the primary formatter used to format the suggestions.

If src is not same as dest, copies it and changes the permission mode to mode. If dest is a directory, destination is dest/src. This method removes destination before copy.

FileUtils.install 'ruby', '/usr/local/bin/ruby', mode: 0755, verbose: true
FileUtils.install 'lib.rb', '/usr/local/lib/ruby/site_ruby', verbose: true
