Variables & Types

Legacy page. This page predates the v0.2 redesign and may show syntax the v0.1.11 interpreter does not accept. It will be rewritten in P7 Docs truth.

Variable Declarations

PooLang uses the poo keyword to declare variables. By default, variables are immutable, meaning their value cannot be changed after assignment.

poo age << 5;

If you need to reassign a value, you must use the mut keyword:

poo mut score << 0;
score << 10; # This is allowed

Assignment Operator

Note that PooLang uses the << operator for assignment instead of the traditional =. This helps distinguish PooLang code at a glance.

Supported Types

1. Integer: Whole numbers (e.g., 42, -10).
2. Float: Decimal numbers (e.g., 3.14, 2.0).
3. String: Text enclosed in double quotes (e.g., "Hello").
4. Boolean: Truth values (true or false).
5. Vector: A collection of values (e.g., [1, 2, 3]).

Type Inference

PooLang automatically infers the type of a variable based on the value assigned to it. You do not need to explicitly declare types for variables.
