compile_file (p1, *args, p3 = {})
public
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, of
the Ruby iseq compiler.
For details regarding valid compile options
see ::compile_option= .
