Objection

Objection is a (currently unimplemented) interpreted programming language with one tenet: anything and everything is an object.

Objective C's syntax highlighting will be used for examples here, as it fits pretty well.

Types

Primitives

• char, uchar, short, ushort, int, uint, long, ulong
  Stores an integer with varying precision.
  Example: 13uc, -16s, 717, 8305ul
• float, double
  Stores a floating point number with varying precision.
  Example: 13.5f, 1e20d
• string
  Stores a string of text.
  Example: "Hello there!"
  All strings have .format(any... value) to allow string formatting.
  Also, newlines can be inserted into strings with no difficulty.
• bool
  Stores a 1-bit value.
  Example: true, false
• vec
  Stores an ordered, immutable group of values.
  Example: (1, 2, 3)
• list
  Stores an ordered, mutable group of values.
  Example: [1, 2, 3]
• group
  Stores an unordered, immutable group of values.
  Example: |(1, 2, 3)|
• set
  Stores an unordered, mutable group of values.
  Example: |[1, 2, 3]|
• any
  Abstract, can represent any type of value.
  Variables of this type aren't type-checked.

Functional

• annotation
  The annotation for a type or function.
  Example: <int>, <float, <int, bool>>
• argument
  An argument specifier in a function signature.
  Example: x: int, y: function<int>
• type
  A class. Will touch on later.
  Examples: { public x: int = 6; }, int, bool
• signature
  The concatenation of a vec<annotation> and an argument.
  Example: (x: int)<float>
• function The concatenation of an argument and a type.
  Example: <int>{return 5;}
• callable The concatenation of either a vec<annotation> and a function, or a signature and a type.
  Example: (x: int)<int>{return x * 2;}
• partial The concatenation of a callable and a vec<any>. Not ran yet.
  Example: (x: int)<int>{return x * 2;}(5)
• runner Only the built-in value ! can have this type. Runs a partial when concatenated with one.
  Example: !((x: int)<int>{return x * 2;}(5)) == 10

Syntax

Notice how this is still in the Types section.

• keyword A keyword. New ones can't be made (how would that work?)
  Examples: if, for
• operator A two-argument operator.
  All operators implement concat = (other: std::ops::assign)<operator> to allow in-place mutation.
  Example:

  (5 (operator)->{ // subclass of operator, will be touched on later
    public operate: callable<int> = (a: int, b: int)<int>{return a+b;};
  } 8) == 13

Built-ins

• null
any - Represents the abscence of a value.
• !
runner - Runs a partial when concatenated with one.
• public
keyword - Allows a value of a type to be accessed externally.
• +, -, *, /, %, **
operator - Arithmetic operators.
• ==, ~=, <, >, <=, >=
operator - Comparison operators.
• &&, ||, ^, ~
operator - Bitwise operators. ~ represents not.
• import
keyword - Allows importing a file as a type.
  Example: import (utils: "./utils.ob");
• print
callable - Outputs to stdout.
  Example: !print("Hello, world!\n");
• input
callable - Gets a line of input from stdin.
  Example: !input("Input your name: ");
