Takes source, which can be a string of Ruby code, or an open File object. that contains Ruby source code.

Optionally takes file, path, and line which describe the file path, real path and first line number of the ruby code in source which are metadata attached to the returned iseq.

file is used for ‘__FILE__` and exception backtrace. path is used for require_relative base. It is recommended these should be the same full path.

options, which can be true, false or a Hash, is used to modify the default behavior of the Ruby iseq compiler.

For details regarding valid compile options see ::compile_option=.

RubyVM::InstructionSequence.compile("a = 1 + 2")
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>

path = "test.rb"
RubyVM::InstructionSequence.compile(File.read(path), path, File.expand_path(path))
#=> <RubyVM::InstructionSequence:<compiled>@test.rb:1>

file = File.open("test.rb")
RubyVM::InstructionSequence.compile(file)
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>:1>

path = File.expand_path("test.rb")
RubyVM::InstructionSequence.compile(File.read(path), path, path)
#=> <RubyVM::InstructionSequence:<compiled>@/absolute/path/to/test.rb:1>

Takes body, a Method or Proc object, and returns a String with the human readable instructions for body.

For a Method object:

# /tmp/method.rb
def hello
  puts "hello, world"
end

puts RubyVM::InstructionSequence.disasm(method(:hello))

Produces:

== disasm: <RubyVM::InstructionSequence:hello@/tmp/method.rb>============

For a Proc object:

# /tmp/proc.rb
p = proc { num = 1 + 2 }
puts RubyVM::InstructionSequence.disasm(p)

Produces:

Sends a DELETE request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Delete object created from string path and initial headers hash initheader.

http = Net::HTTP.new(hostname)
http.delete('/todos/1')

Sends a MOVE request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Move object created from string path and initial headers hash initheader.

http = Net::HTTP.new(hostname)
http.move('/todos/1')

Sends a DELETE request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Delete object created from string path and initial headers hash initheader.

http = Net::HTTP.new(hostname)
http.delete('/todos/1')

Sends a MOVE request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Move object created from string path and initial headers hash initheader.

http = Net::HTTP.new(hostname)
http.move('/todos/1')

Sets the body for the request:

req = Net::HTTP::Post.new(uri)
req.body # => nil
req.body = '{"title": "foo","body": "bar","userId": 1}'
req.body # => "{\"title\": \"foo\",\"body\": \"bar\",\"userId\": 1}"

Returns the string response body; note that repeated calls for the unmodified body return a cached string:

path = '/todos/1'
Net::HTTP.start(hostname) do |http|
  res = http.get(path)
  p res.body
  p http.head(path).body # No body.
end

Output:

"{\n  \"userId\": 1,\n  \"id\": 1,\n  \"title\": \"delectus aut autem\",\n  \"completed\": false\n}"
nil

Sets the body of the response to the given value.

Args

v

String

Description

Public setter for the typecode v (with validation).

See also URI::FTP.check_typecode.

Usage

require 'uri'

uri = URI.parse("ftp://john@ftp.example.com/my_file.img")
#=> #<URI::FTP ftp://john@ftp.example.com/my_file.img>
uri.typecode = "i"
uri
#=> #<URI::FTP ftp://john@ftp.example.com/my_file.img;type=i>

Appends sep to the text to be output. By default sep is ‘ ’

width argument is here for compatibility. It is a noop argument.

Compile the query into a callable object that can be used to match against nodes.

True if the command handles the given argument list.

Does this dependency require a prerelease?

A null NameTuple, ie name=nil, version=0

Indicate if this NameTuple is for a prerelease version.

A requirement is a prerelease if any of the versions inside of it are prereleases

A version is considered a prerelease if it contains a letter.

The release for this version (e.g. 1.2.0.a -> 1.2.0). Non-prerelease versions return themselves.

Removes all sources from the SourceList.

Deletes source from the source list which may be a Gem::Source or a URI.
