Tress Playground
Statically typed, interpreted scripting language running in a custom AST interpreter client-side. Select an example to test its type checking and execution.
1. Static Variable Declarations
init <type>: <name> = <value>
Supported types: int, str, float, bool, int? (Optional)
init int: x = 42 init str: greeting = "Hello, Tress!" init float: pi = 3.14159
2. Variable Assignment & Mutation
<name> = <expression>
Value type must match the declared static type.
x = x + 10 greeting = "Updated string"
3. Control Flow & Loops
while (cond) { ... } | if (cond) { ... }
Supports comparisons (==, !=, <, >, <=, >=).
init int: i = 1
while (i <= 5) {
disp("Loop:", i)
i = i + 1
}
4. Built-in Functions & Math
disp(...) | sqrt(n) | abs(n) | floor(n)
Print output or run math functions.
disp("Square root:", sqrt(100))
disp("Absolute:", abs(-42))
