Romasm IDE

Integrated Development Environment for writing and debugging Romasm code

Overview

The Romasm IDE (ide.html) is a web-based development environment for writing, assembling, and executing Romasm assembly code. It provides a complete coding experience in your browser.

Features

Code Editor

A text area for writing Romasm assembly code with syntax highlighting support.

  • Write your Romasm programs
  • Save and load code examples
  • Pre-defined examples in dropdown

Assemble & Run

One-click assembly and execution:

  • Assemble: Converts your code to instructions
  • Run: Executes the program in the VM
  • Step: Execute one instruction at a time (debugging)

Output Console

View program output and errors:

  • PRINT instruction output
  • Assembly errors
  • Runtime errors
  • Final register states

Memory Visualization

View the contents of VM memory:

  • See all memory addresses and values
  • Track memory changes during execution
  • Debug memory-related issues

Example Programs

Pre-loaded examples covering:

  • Basic arithmetic
  • Loops and conditionals
  • Mathematical functions (factorial, power, sqrt)
  • Trigonometric functions (sine, cosine)
  • Calculus operations (derivatives, integrals)

Using the IDE

Step 1: Write Your Code

Type or paste your Romasm assembly code into the editor:

LOAD R0, 10
LOAD R1, 20
ADD R0, R1
PRINT R0

Step 2: Assemble

Click the "Assemble" button to convert your code to instructions. Check for any assembly errors.

Step 3: Run

Click "Run" to execute your program. View the output in the console below.

Step 4: Debug

Use "Step" to execute one instruction at a time, or check the memory visualization to see what's stored.

Example Programs

The IDE includes several example programs you can load from the dropdown:

  • Basic Arithmetic - Simple addition and multiplication
  • Factorial - Calculate n! using a loop
    • Power Function - Calculate base^exponent
  • Square Root - Newton's method for √n
  • Sine Function - Taylor series sine calculation
  • Derivative - Numerical differentiation
  • Integral - Numerical integration (trapezoidal rule, Simpson's rule)

Tips & Tricks

Using Standard Library

To use stdlib functions in the IDE, you may need to:

  • Include stdlib code directly in your program, or
  • Use the linker system (if enabled)

For easier stdlib usage, try the Romasm Calculator which has automatic linking.

Debugging

  • Use PRINT statements to output intermediate values
  • Check the memory visualization to see stored values
  • Use "Step" mode to execute one instruction at a time
  • Check final register states after execution
