Kex Programming Language Docs

Kex is a dynamically typed, interpreted programming language designed for simplicity and ease of use. It supports basic arithmetic operations, variable assignments, and data structures like lists and dictionaries.

Basic Syntax

Data Types

Kex supports the following data types:

• Text Type
  • String (str)
• Numeric Type
  • Integer (int)
  • Float (float)
• Boolean Type (bool)
• Sequence Type
  • List (list)
  • Tuple (tuple)
• Mapping Type
  • Dictionary (dict)

Variables and Assignment

Variables in Kex are dynamically typed and can be assigned using the = operator:

x = 5
name = "Alice"

Arithmetic Operations

Kex supports basic arithmetic operations:

• Addition: +
• Subtraction: -
• Multiplication: *
• Division: /

Example:

result = 10 + 5 * 2

Lists

Lists are created using square brackets:

numbers = [1, 2, 3, 4, 5]

Dictionaries

Dictionaries are created using curly braces:

person = {"name": "Bob", "age": 30}

Comments

Kex supports both single-line and multi-line comments:

// This is a single-line comment

/*
This is a
multi-line comment
*/

Language Features

• Expression Evaluation: Kex evaluates expressions and can handle nested arithmetic operations.
• Variable Scope: The language uses a simple symbol table for variable management, suggesting it has a global scope for variables.
• Error Handling: Basic error handling is implemented, including syntax errors and undefined variable errors.
• Interactive Mode: The language can be used in an interactive REPL (Read-Eval-Print Loop) mode.

Limitations

Based on the current implementation, Kex has several limitations:

• No control structures (if/else, loops) are implemented.
• Functions are not supported.
• There's no module or import system.

Usage

To use Kex, run the interpreter and input expressions or statements at the prompt:

kex> x = 10
kex> y = 20
kex> x + y
30

Future Plans

• Immediate (I):

  • Feature Addition: Conditional Operators

• Short Period (S):

  • Feature Addition: Control Flow Statements
  • Feature Addition: Add Documentation Capability (docstring)

• Long Run (L):

  • Feature Addition: File Handling
  • Feature Addition: Exception Handling
