Question

Does OCaml have a way to get the current file/module/script name? Something like:

• C/C++’s argv[0]
• Python’s sys.argv[0]
• Perl/Ruby’s $0
• Erlang’s ?FILE
• C#’s ProgramName.Environment.CommandLine
• Factor’s scriptname/script
• Go’s os.Args[0]
• Haskell’s System/getProgName
• Java’s System.getProperty("sun.java.command").split(" ")[0]
• Node.js’s __filename
• etc.

Answer 1

let _ =
    let program = Sys.argv.(0) in
        print_endline ("Program: " ^ program)
