OSL ‐ Variables

Variable Assignment:

• variablename = "assign-data":
  • This command sets a variable with the specified name (variablename) to the inputted data ("assign-data").
  • Example: count = 10 sets the variable count to the value 10.
  • Setting a variable to an array: array = ["hello","world"] sets the variable array to the value ["hello","world"]

List Item Assignment:

• list.[itemnumber] = "assign-data":
  • This command sets the selected item of a list (specified by [itemnumber]) to the inputted data ("assign-data").
  • Example: mylist.[2] = "new_value" sets the third item in the list mylist to the value "new_value".

JSON Object Key Assignment:

• object.key("key") = "assign-data":
  • This command sets the selected key of a JSON object (specified by "key") to the inputted data ("assign-data").
  • Example: myobject.key("name") = "John" sets the value associated with the key "name" in the JSON object myobject to "John".

Arithmetic Modifiers:

• variable += 10:

  • This code appends ten to the end of a string or adds ten to a number data type.
  • Example: count += 5 would increment the value of the variable count by 5.

• variable *= 5:

  • Sets the variable to itself multiplied by 5. This operation works only on number data types.
  • Example: total *= 2 would double the value of the variable total.

• variable /= 5:

  • Sets the variable to itself divided by 5. This operation works only on number data types.
  • Example: price /= 2 would halve the value of the variable price.

• variable -= 5:

  • Sets the variable to itself minus 5. This operation works only on number data types.
  • Example: balance -= 10 would subtract 10 from the value of the variable balance.

These commands and modifiers allow you to manipulate variables, lists, and JSON objects, performing assignments and arithmetic operations as needed in your script.
