AbbyScript Examples

This directory contains example programs demonstrating various features of AbbyScript.

Console Logging Examples (NEW!)

console_logging.abs

Comprehensive demonstration of the new console.log functionality:

• Single variable logging: console.log(variable)
• String literals: console.log("text")
• Mixed arguments: console.log("text:", variable)
• Multiple console.log calls in one program

variables_demo.abs

Simple demonstration of variable assignment and console output:

• Variable declarations with single-digit numbers (0-9)
• Mixed string and variable console logging
• Multiple console.log statements

number_literals.abs

Tests different ways to output numbers:

• Direct number literals (compile-time conversion)
• Variable numbers (runtime conversion)
• Comparison between literal and variable output

Memory and Storage Examples

memory_operations.abs

Demonstrates memory and storage operations:

• Array-like syntax for storage operations
• Memory operations with array syntax
• Implicit memory assignment

Language Features

arithmetic.abs

Basic arithmetic operations

conditional.abs

If/else conditional statements

functions.abs

Function declarations and calls

storage.abs

Storage operations

simple_js_syntax.abs

JavaScript-like syntax examples

simple_js_no_loops.abs

JavaScript syntax without loops

Usage

Compile and run any example:

# Compile only
./target/debug/abby_evm compile --file examples/abbyscript/console_logging.abs

# Compile and execute
./target/debug/abby_evm execute --bytecode $(./target/debug/abby_evm compile --file examples/abbyscript/variables_demo.abs 2>/dev/null | grep 'Bytecode:' | cut -d' ' -f2)

Recent Updates

✅ Console.log with Variables: Console logging now supports both string literals and variables
✅ Multi-argument Support: console.log("text:", variable) with automatic spacing
✅ Single-digit Numbers: Full support for displaying numbers 0-9
✅ Mixed Output: Can combine strings and variables in the same program

Current Limitations

• Number display currently supports single digits (0-9)
• Multi-digit numbers will need extended conversion algorithms
• Complex expressions in console.log arguments have limited support
