YOLOL
Summary
YOLOL is the programming language used to control and manage electric devices.
The code is written on lines in chips which are then inserted to chip sockets, that read and relay their messages.
With YOLOL, it's possible to program and control almost any device within the known universe.
Basic information
How it works?
YOLOL code is written to and executed from YOLOL chips, and can be used to monitor and control electrical devices connected to the data network the chip is connected to.
Lines of code are executed in sequence from top to bottom, repeating the cycle of the chip after the last line has been executed, unless the script includes instructions for specific line changes, or stopping code completely.
To put it simply:
- Code execution starts from line 1
- After reading line 1, it proceeds to the next line based on the chip time interval
- The process is repeated
- If there are no special cases, the chip will begin executing line 1 again after the last line has been executed

Case insensitive
YOLOL is fully case insensitive.
This means that the following two example scripts function identically to each other:
if ButtonState == 1 then DoorState = 1 end
IF buttonstate == 1 THEN doorstate = 1 END
The characters can however be written in either lowercase or uppercase letters.
This way it's possible to have your YOLOL code look a bit more organized.
Variables
The variables in YOLOL are weakly typed (don't enforce type validity), and support two data types: fixed-point decimals(up to 0.001 precision) and strings.
To put it simply, the variables can either be introduced as strings or numbers at any point, ignoring the earlier variable type.
Each variable is always of a single type, though it will be implicitly converted when required.
The default value of an uninitialized variable is 0, and nil values are not supported.
True/False are numerical values of non-0 and 0.
Assigning a value to a variable always converts the variable to the value's type.
Example:
ultimateAutopilot= 128.6432
This results in the variable ultimateAutopilot containing a numeric value of 128.6432
ultimateAutopilot= "Error prone"
This results in the variable ultimateAutopilot to be a string variable "Error prone", and numeric value of 128.6432 is removed.
Decimals
Numeric values in YOLOL are 64-bit integers.
The variables hold decimal numbers up to four decimal accuracy
pieVariable= 3.1415
The above script assigns a numeric value of 3.1415 to the variable pieVariable.
Supplying more precise values than the variables can store works, but doesn't affect the end result.
notPieVariable= 0.5772156649
The above script assigns a numeric value of 0.5772 to the variable notPieVariable.
Strings
To specify a string literal in YOLOL, the desired string value must be surrounded with double quotation marks.
stringStorage= "saltberia"
This script assigns the string value of "saltberia" to the variable stringStorage.
Device fields / External variables
External variables and device fields can be used within the YOLOL programming with the following syntax:
- :variableName
- variableName being the configured device field id.
A programmable chip that is connected to a device has access to all the devices in the same network.
It can then modify and listen to any device fields it has access to.
The prefix ':' is used to tell the script that we are trying to access an external variable, instead of using one that may or may not be declared/used in the script.
if :ButtonState == 1 then :DoorState = 1 end
The script above will send the value of 1 to any devices listening to the device field 'DoorState' if the value of ButtonState is 1 in the data network.
Operators and commands
Note that the available operators may be limited by the type of YOLOL chip.
Basic chips have a limited selection of functions while more advanced ones can perform more complex operations natively.
Basic arithmetic and assignment operators
| Operation | Numeric operation | String operation |
|---|---|---|
| A + B | Addition | String A is appended by String B. |
| A - B | Subtraction | The last appearance of String B in String A is removed from String A. |
| A * B | Multiplication | Runtime error. The rest of the line is skipped. |
| A / B | Division | Runtime error. The rest of the line is skipped. |
| A ++ | PostIncrement (A=A+1) | Appends a space to String A. Evaluates to the original value. |
| A -- | PostDecrement (A=A-1) | Removes the last character of the string. Results in runtime error when trying to remove "". Evaluates to the original value. |
| ++ A | PreIncrement (A=A+1) | Appends a space to String A. Evaluates to the modified value. |
| -- A | PreDecrement (A=A-1) | Removes the last character of the string. Results in runtime error when trying to remove "". Evaluates to the modified value. |
| A = B | Assignment (Variable A is set to the value of variable B) | Assignment |
| A += B | Addition-assignment (A=A+B) | A is assigned the value of string-operation A+B |
| A -= B | Subtraction-assignment (A=A-B) | A is assigned the value of string-operation A-B |
| A *= B | Multiplication-assignment (A=A*B) | Runtime error for string variables. The rest of the line is skipped. |
| A /= B | Division-assignment (A=A/B) | Runtime error for string variables. The rest of the line is skipped. |
| A %= B | Modulo-assignment (A=A%B) | Runtime error for string variables. The rest of the line is skipped. |
| A ^ B | Exponentiation | Runtime error for string variables. The rest of the line is skipped. |
| A % B | Modulo | Runtime error for string variables. The rest of the line is skipped. |
| ABS A | Modulus (absol value) (A=A if A>=0, else A=-A) | Runtime error for string variables. The rest of the line is skipped. |
| A! | Factorial | Runtime error for string variables. The rest of the line is skipped. |
| SQRT A | Square root of A | Runtime error for string variables. The rest of the line is skipped. |
| SIN A | Sine of A (degrees) | Runtime error for string variables. The rest of the line is skipped. |
| COS A | Cosine of A (degrees) | Runtime error for string variables. The rest of the line is skipped. |
| TAN A | Tangent of A (degrees) | Runtime error for string variables. The rest of the line is skipped. |
| ARCSIN A | Inverse sine of A (degrees) | Runtime error for string variables. The rest of the line is skipped. |
| ARCCOS A | Inverse cosine of A (degrees) | Runtime error for string variables. The rest of the line is skipped. |
| ARCTAN A | Inverse tangent of A (degrees) | Runtime error for string variables. The rest of the line is skipped. |
Logical operators
Logical operators are checks, whether or not statement is true or false. All logical operations return either 0 (for False) or 1 (for True)
| Operation | Numeric operation | String operation |
|---|---|---|
| A < B | Less than | returns 1 if String A is first in alphabetical order, returns 0 if not. |
| A > B | Greater than | returns 0 if String A is first in alphabetical order, returns 1 if not. |
| A <= B | Less than or equal to | returns 1 if String A is first in alphabetical order or identical to String B, returns 0 if not. |
| A >= B | Greater than or equal to | returns 0 if String A is first in alphabetical order or identical to String B, returns 1 if not. |
| A ~= B | Not equal to | returns 1 if String A is not equal to String B, 0 if it is. |
| A == B | Equal to | returns 1 if String A is equal to String B, 0 if not. |
You can also use the not, and and or keywords to set up more complicated conditions than simple variable value checks.
Mixing variable types in operations
Mixing variable types in an operation handles the operation using all parameters as strings.
previouslyNumber= "10" + 15
The above script results in previouslyNumber containing the string value "1015".
Note that the involved parameters themselves don't change types, their values are just cast as strings for the purpose of the operation:
purelyNumber = 15 purelyString = "10" + purelyNumber
When this script has executed, purelyString contains the string value of "1015", while purelyNumber still contains the numeric value of 15.
