Method: RubyVM::InstructionSequence.new

Defined in:

iseq.c

.compile(source[, file[, path[, line[, options]]]]) ⇒ Object .new(source[, file[, path[, line[, options]]]]) ⇒ Object

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>
