Command-line options

The Sidef interpreter has the following command-line options:

Usage: sidef [switches] [--] [programfile] [arguments]

  -c            compile the code into a Perl program
  -C            check syntax only
  -D            dump the syntax tree of a program
  -E program    one line of program
  -H            interactive help
  -i            interactive mode
  -k            keep track of potentially incorrect parser interpretations
  -M mode       set the rounding mode of floating-point numbers
                valid modes: [near], zero, inf, +inf, -inf, faith
  -N options    modify class-variables inside the Number class
                valid format: 'VERBOSE=1; USE_YAFU=1; USE_PRIMECOUNT=1'
  -o file       file where to dump the output
  -O level      perform code optimizations before execution
                valid levels: [0], 1, 2

  -r            parse and deparse a Sidef program

                valid values: sidef, perl
  -s            save compiled code in a database to reduce boot-time
  -t            treat all command-line arguments as scripts
