Used internally to indicate that a dependency conflicted with a spec that would be activated.

A set of gems for installation sourced from remote sources and local .gem files

Represents an installed gem. This is used for dependency resolution.

Class for representing WebDAV method MOVE:

require 'net/http'
uri = URI('http://example.com')
hostname = uri.hostname # => "example.com"
req = Net::HTTP::Move.new(uri) # => #<Net::HTTP::Move MOVE>
res = Net::HTTP.start(hostname) do |http|
  http.request(req)
end

Related:

• Net::HTTP#move: sends MOVE request, returns response object.

Raised when a bad requirement is encountered

A progress reporter that prints out messages about the current progress.

Description

An FFI closure wrapper, for handling callbacks.

Example

closure = Class.new(Fiddle::Closure) {
  def call
    10
  end
}.new(Fiddle::TYPE_INT, [])
   #=> #<#<Class:0x0000000150d308>:0x0000000150d240>
func = Fiddle::Function.new(closure, [], Fiddle::TYPE_INT)
   #=> #<Fiddle::Function:0x00000001516e58>
func.call
   #=> 10

This exception is raised if a parser error occurs.

This exception is raised if a generator or unparser error occurs.

This class works in conjunction with Psych::Parser to build an in-memory parse tree that represents a YAML document.

Example

parser = Psych::Parser.new Psych::TreeBuilder.new
parser.parse('--- foo')
tree = parser.handler.root

See Psych::Handler for documentation on the event methods used in this class.

Subclass of Zlib::Error

When zlib returns a Z_MEM_ERROR, usually if there was not enough memory.

Subclass of Zlib::Error. This error is raised when the zlib stream is currently in progress.

For example:

inflater = Zlib::Inflate.new
inflater.inflate(compressed) do
  inflater.inflate(compressed) # Raises Zlib::InProgressError
end

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.

• each

• each_line

• each_byte

• gets

• getc

• lineno

• lineno=

• read

• readchar

• readline

• readlines

• ungetc

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.
