Zlib::GzipReader is the class for reading a gzipped file. GzipReader should be used as an IO, or -IO-like, object.
Zlib::GzipReader.open('hoge.gz') {|gz| print gz.read } File.open('hoge.gz') do |f| gz = Zlib::GzipReader.new(f) print gz.read gz.close end
Method Catalogue The following methods in Zlib::GzipReader are just like their counterparts in IO, but they raise Zlib::Error or Zlib::GzipFile::Error exception if an error was found in the gzip file.
Be careful of the footer of the gzip file. A gzip file has the checksum of pre-compressed data in its footer. GzipReader checks all uncompressed data against that checksum at the following cases, and if it fails, raises Zlib::GzipFile::NoFooter, Zlib::GzipFile::CRCError, or Zlib::GzipFile::LengthError exception.
When an reading request is received beyond the end of file (the end of compressed data). That is, when Zlib::GzipReader#read, Zlib::GzipReader#gets, or some other methods for reading returns nil.
When Zlib::GzipFile#close method is called after the object reaches the end of file.
When Zlib::GzipReader#unused method is called after the object reaches the end of file.
The rest of the methods are adequately described in their own documentation.

exception to wait for reading by EWOULDBLOCK. see IO.select.
exception to wait for writing by EINPROGRESS. see IO.select.
The DidYouMean::Formatter is the basic, default formatter for the gem. The formatter responds to the message_for method and it returns a human readable string.

Raised when the provided IP address is an invalid address.
Raised when the address family is invalid such as an address with an unsupported family, an address with an inconsistent family, or an address who’s family cannot be determined.
Raised when the address is an invalid length.
Response class for Created responses (status code 201).
The Created response indicates that the server has received and has fulfilled a request to create a new resource.
References:
Response class for Not Modified responses (status code 304).
Indicates that the resource has not been modified since the version specified by the request headers.
References:
Response class for Not Implemented responses (status code 501).
The server either does not recognize the request method, or it lacks the ability to fulfil the request.
References:
ReadTimeout, a subclass of Timeout::Error, is raised if a chunk of the response cannot be read within the read_timeout.
This represents the result of a call to ::parse or ::parse_file. It contains the requested structure, any comments that were encounters, and any errors that were encountered.
This is a result specific to the parse and parse_file methods.
This is a result specific to the lex and lex_file methods.
This is a result specific to the parse_lex and parse_lex_file methods.
Indicates a timeout resolving a name or address.
An error that indicates we weren’t able to fetch some data from a source
