The /var command can be used to replace the value of existing variables or create a new variables and assign them values. By default /var creates local variable, this can be changed via the -g switch (/set command can be used to set global variables by default).

The var command can perform one math operation via one of the arithmetic operators: addition (+), subtraction (-), multiplication (*), division (/), and modulo (%). They must be space delimited with both operands being a number. If any of the operands are not a number or if a space is missing, it will be treated as plain text.


Note: Unlike the /set command, var can assign a value to multiple variables at once.

Set Evaluation Routine: Internally, the var command simply breaks down the line (by commas) and passes the arguments to /set. The set command has its own evaluation routine which lets you dynamically concatenate additional values onto the variable name before the assignment takes place.

//var -ls % $+ $ctime ABC

Will create a variable like %1209425041 with the value of 'ABC'; Similarly this can be used with $nick and $chan in on events.

Synopsis

/var [-sg] <%var> [[= ]value]
/var [-sg] <%var> <number> <+ | - | * | / | %> <number>
/var [-sg] <%var> [= ]<number> <+ | - | * | / | %> <number>
/var [-sg] <%var> [[= ]value][, <%var> [[= ]value]][, ...]
/var [-sg] <%var> [= ]<number> <+ | - | * | / | %> <number>[, ...]

Switches

  • -s - Display variable assignment value
  • -g - Creates a global variable instead
  • -n - Treats value as plain text

Parameters

  • <%var> - The name of the variable
  • [value] - The value to assign to the variable
  • <number> - Any arbitrary numerical value, can be a floating point number
  • <+ | - | * | / | %> - One of the five possible arithmetic operations
  • <number> - Any arbitrary numerical value, can be a floating point number

Example

; Factorial
; 10! = $factorial(10) = 3628800
alias factorial {
  var %result = 1, %x = $1
  while (%x) {
    var %result = %result * $v1
    dec %x
  }
  return %result
}
