Operators

Operators are used to modify data and return it, for example to do arithmetic. They are classified as nilary, unary, binary or ternary depending on the number of arguments they take, and non-lazy or lazy depending on whether they take their arguments in evaluated form or non-evaluated form. There are also some operators that use their own syntax. In verbose mode they take the form of functions, similar to commands. Operands are denoted by x, y, z and a respectively.

Non-lazy

Nilary

Operator	Verbose	Returns
`Ｓ`	`InputString`	The next input as a string.
`Ｎ`	`InputNumber`	The next input as a number.
`‽`	`Random`	0 or 1 with equal chance.
`ＫＡ`	`PeekAll`	Every cell on the canvas, from left to right and top to bottom.
`ＫＭ`	`PeekMoore`	Cells in a Moore neighborhood around the cursor
`ＫＶ`	`PeekVonNeumann`	Cells in a Von Neumann neighborhood around the cursor.
`ＫＫ`	`Peek`	The character under the cursor.

Unary

Operator	Verbose	Returns
`±`	`Negate`	`-x`.
`Ｌ`	`Length`	The length of `x`.
`¬`	`Not`	`False` if `x` is truthy, else `True` if `x` is falsy.
`Ｉ`	`Cast`	`x` as a string if it is a number, or `x` as a number if it is a string.
`‽`	`Random`	A random integer between 0 and `x`, each number having equal chance to appear, or a randomly selected character if `x` is a string or a random element if `x` is a list.
`Ｖ`	`Evaluate`/`eval`	The result after executing `x` as a string.
`⊟`	`Pop`	The last value in `x`, after removing it from `x`.
`↧`	`Lowercase`	The lowercase equivalent of `x` if it has one.
`↥`	`Uppercase`	The uppercase equivalent of `x` if it has one.
`⌊`	`Minimum`	The minimum value in `x`.
`⌈`	`Maximum`	The maximum value in `x`.
`℅`	`Character`/`Ordinal`/`chr`/`ord`	The character code of `x` if `x` is a character, or the character `x` is the character code of if `x` is an integer.
`⮌`	`Reverse`	`x` reversed.
`～`	`BitwiseNot`	The 2's complement of `x`.

Binary

Operator	Verbose	Returns
`⁺`	`Add`/`Plus`	`x+y`.
`⁻`	`Subtract`/`Minus`	`x-y`, or `x` with `y` deleted if both `x` and `y` are strings.
`×`	`Multiply`/`Times`	`x*y`.
`÷`	`IntDivide`/`IntegerDivide`	`x//y`.
`∕`	`Divide`	`x/y`.
`﹪`	`Modulo`	`x%y`. Note that this can be used to format strings.
`⁼`	`Equals`	Whether `x` is equal to `y`.
`‹`	`Less`	`<`
`›`	`Greater`	`>`
`…·`	`InclusiveRange`	`[x, y]` over the integers or characters.
`…`	`Range`	`[x, y)` over the integers or characters.
`…`	`CycleChop`	`x` repeated and chopped to length `y`.
`Ｘ`	`Exponentiate`/`Exponent`/`Power`	`x` to the power of `y`.
`§`	`AtIndex`	`x[y]`, wrapping if needed.
`⊞Ｏ`	`PushOperator`	`x` after pushing `y` to `x`.
`⪫`	`Join`	The result of joining `x` with `y`.
`⪪`	`Split`	The result of splitting `x` with `y`.
`⌕Ａ`	`FindAll`	The indices of `y` in `x`.
`⌕`	`Find`	The index of `y` in `x`.
`◧`	`PadLeft`	The result of left-padding `x` with `y`.
`◨`	`PadRight`	The result of right-padding `x` with `y`.
`№`	`Count`	The number of occurrences of `y` in `x`.

Quaternary

Operator | Verbose | Returns ✂ | Slice | Every a items of x starting at y until (but not including) z.

Lazy

Binary

Operator	Verbose	Returns
`∧`	`And`/`and`	`y` if `x` and `y` are both truthy else `False`. Short-circuits.
`∨`	`Or`/`or`	`y` if `y` is truthy, else `x` if `x` is truthy, else `False`. Short-circuits.

Ternary

Operator	Verbose	Returns
`⎇`	`Ternary`	`y` if `x` is truthy else `z`.

Other

Operator	Verbose	Arguments	Returns
`ＫＤ`	`PeekDirection`	`exp dir`	The cells in a line of length `x` in the direction `y` from the cursor, including the cell under the cursor.
`Ｅ`	`Each`/`Map`	`exp exp`	An array `arr` where `arr[i]` is `y(x[i])`.
`ＵＰ`	`PythonFunction`	`str lst`	Gets the function with a return value `x` from Python, and runs it with `y` as arguments.
