Returns the number of the first source line where the instruction sequence was loaded from.

For example, using irb:

iseq = RubyVM::InstructionSequence.compile('num = 1 + 2')
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>
iseq.first_lineno
#=> 1

Takes source, which can be a string of Ruby code, or an open File object. that contains Ruby source code. It parses and compiles using parse.y.

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

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

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

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

Takes source, which can be a string of Ruby code, or an open File object. that contains Ruby source code. It parses and compiles using prism.

RubyVM::InstructionSequence.compile_prism("a = 1 + 2")

#=> <RubyVM::InstructionSequence:<compiled>@/absolute/path/to/test.rb:1>

Takes file, a String with the location of a Ruby source file, reads, parses and compiles the file, and returns iseq, the compiled InstructionSequence with source location metadata set.

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

# /tmp/hello.rb
puts "Hello, world!"

# elsewhere
RubyVM::InstructionSequence.compile_file("/tmp/hello.rb")
#=> <RubyVM::InstructionSequence:<main>@/tmp/hello.rb>

Take a location from the prism parser and set the necessary instance variables.

Posts data to a host; returns a Net::HTTPResponse object.

Argument url must be a URI; argument data must be a hash:

_uri = uri.dup
_uri.path = '/posts'
data = {title: 'foo', body: 'bar', userId: 1}
res = Net::HTTP.post_form(_uri, data) # => #<Net::HTTPCreated 201 Created readbody=true>
puts res.body

Output:

{
  "title": "foo",
  "body": "bar",
  "userId": "1",
  "id": 101
}

puts res.body

Output:

{
  "title": "foo",
  "body": "bar",
  "userId": "1",
  "id": 101
}

Sets the encoding that should be used when reading the body:

• If the given value is an Encoding object, that encoding will be used.

• Otherwise if the value is a string, the value of Encoding#find(value) will be used.

• Otherwise an encoding will be deduced from the body itself.

Examples:

http = Net::HTTP.new(hostname)
req = Net::HTTP::Get.new('/')

http.request(req) do |res|
  p res.body.encoding # => #<Encoding:ASCII-8BIT>
end

http.request(req) do |res|
  res.body_encoding = "UTF-8"
  p res.body.encoding # => #<Encoding:UTF-8>
end

Validates typecode v, returns true or false.

Private setter for the typecode v.

Return the byte offset of the start of the line corresponding to the given byte offset.

Return the column number in characters for the given byte offset.

Return the column number in characters for the given byte offset.

These are the comments that are associated with this location that exist after the end of this location.

Attach a comment to the trailing comments of this location.

The line number where this location starts.
