ctack's Issues

tokenizer

it is what it is

Variant type

Currently, we have only integer type. We need to do more type but I want to implement dynamically typed variables called variants. Variant has that types:

• int
• string (char is simply string)
• bool
• null

Also, arithmetic operators must be updated for dynamic type transformation and operations

[Propsal] Variabels

Users can declare a variable with a name and default value. Variables have a scope lifestyle. This means that the user only has access to it within the same scope. The main file is a global scope.

syntax:

// decleration
var <variable name> <?initial data, optional>

// write data into x from the top of the stack, stack doesn't pop!
store <variable name>

// push data to stack
load <variable name>

// delete variable from this scope
delete <variable name>

[Propsal] function decleration

syntax:

// decleration
// fn name(params)  /* code */  end
fn <func name>([n1, [n2, ...]] )
<function body>
end

// usage
// This func call get params from stack
<func name>

// Spesific params
<func name> 3 5

logic operators

• &&
• ||
• >
• <
• ==
• <=
• >=
• !=
• !

default type check

the if condition

If condition get top element of the stack and if its true run the if block else run the else block.
syntax:

1 if
// code
end

<val1> <val2> <operator> if <true code> else <other code> 

Operators:
==, !=, &&, ||

Condition Logics:
We can use stack manipulation operators, variales or plain data
