Quasar MIPS IDE

Quasar is a modern, high-performance Integrated Development Environment (IDE) for MIPS32 R2000 assembly. Built with Tauri v2, React, and Rust, it provides a lightweight and intuitive experience for students, researchers, and developers to write, debug, and simulate MIPS code with real-time feedback.

Features

• Modern IDE Experience: Sleek, frameless window design with a custom draggable title bar.
• Advanced Theme Engine: Support for dynamic JSON theme plugins (similar to VS Code).
• Multi-Tab Workspace: Manage multiple assembly files simultaneously with intelligent session-based numbering.
• OS-Native Performance: Powered by a high-speed Rust backend for near-instant simulation.
• Professional Console: Real-time message parsing with timestamps, error highlighting, and persistent history.
• Customizable: Personalize your workspace with adjustable font sizes, tab widths, and automation settings.

Simulator Features

The Quasar MIPS Engine supports a comprehensive subset of the MIPS32 R2000 instruction set:

• Arithmetic & Logic: add, sub, and, or, xor, nor, addi, andi, sll, srl, etc.
• Data Transfer: lw, sw, lb, sb, lh, sh, lui.
• Control Flow: beq, bne, slt, slti, j, jal, jr, jalr.
• Special Ops: Full support for mult, div, mfhi, mflo with dedicated HI/LO register tracking.
• Step-by-Step Debugging: Execute instructions one at a time with visual register change highlighting (orange glow).
• System Calls: Integrated syscall support for console I/O.

How to Use

1. Write: Create a new file or open an existing .mips or .asm file.
2. Save: Files must be saved before execution. Enable "Auto-Save before Run" in Settings for a seamless experience.
3. Simulate:
   • Press F5 or click Run to execute the entire program.
   • Press F10 or click Step to debug line-by-line.
4. Observe: Monitor the Registers and Memory panes on the right to see real-time state changes.
5. Reset: Use Ctrl+R or the Reset button to clear state and restart the program.

Installation

Download Binaries

Download the latest installer for your platform from the GitHub Releases page.

• Windows: .msi or .exe
• Linux: .deb or .AppImage

Pre-built Binary (Recommended):

yay -S quasar-mips-ide-bin

Latest Development Version (Build from source):

yay -S quasar-mips-ide-git

Build from Source

To build Quasar from source, ensure you have the following prerequisites installed:

• Node.js (LTS version)
• Rust (Stable toolchain via rustup)
• System Dependencies (Linux only): libgtk-3-dev, webkit2gtk-4.1-dev, libappindicator3-dev, librsvg2-dev

Steps:

1. Clone the repository:

   git clone https://github.com/rmia46/quasar.git
   cd quasar

2. Install frontend dependencies:

   npm install

3. Run in development mode:

   npm run tauri dev

4. Build the production bundle:

   npm run tauri build

The bundled installer for your OS will be located in src-tauri/target/release/bundle/.
