Parse ‘str’ of command ‘cmd’ as an integer between min and max. If either min or max is nil, that value has no bound.
# File lib/ruby-debug/helper.rb, line 9 def get_int(str, cmd, min=nil, max=nil, default=1) return default unless str begin int = Integer(str) if min and int < min print Debugger.printer.print("parse.errors.int.too_low", cmd: cmd, str: str, min: min) return nil elsif max and int > max print Debugger.printer.print("parse.errors.int.too_high", cmd: cmd, str: str, max: max) return nil end return int rescue print Debugger.printer.print("parse.errors.int.not_number", cmd: cmd, str: str) return nil end end
Return true if arg is ‘on’ or 1 and false arg is ‘off’ or 0. Any other value raises RuntimeError.
# File lib/ruby-debug/helper.rb, line 29 def get_onoff(arg, default=nil, print_error=true) if arg.nil? or arg == '' if default.nil? if print_error print Debugger.printer.print("parse.errors.onoff.syntax", arg: "nothing") raise RuntimeError end return default end end case arg.downcase when '1', 'on' return true when '0', 'off' return false else if print_error print Debugger.printer.print("parse.errors.onoff.syntax", arg: arg) raise RuntimeError end end end
