FlightSimulator-Interpreter

Course in C++ programming language - Project 3, first milestone

This project implements an interpreter for a simple domain-specific language geared toward flight simulation.
The interpreter reads commands, expressions, and variable bindings (from input scripts or interactive mode) and executes them in the simulation context.

---

🚀 Features

• Parse and execute commands such as openDataServer, connect, var, print, while, if, equal, etc.
• Expression evaluation (arithmetic, variables, bindings).
• Binding of simulation data variables to local variables (data-binds).
• Reading from a simulated server (data reader) and writing to a simulated client (data writer).
• Control flow support: conditional execution and loops.
• Clean modular architecture: Command classes, Expression classes, DataBind, Reader/Writer, etc.

Getting Started

🧩 Prerequisites

• C++ compiler with C++11 or later support (e.g., g++, clang++)
• CMake (version 3.x)
• A terminal / command-line environment
• A flight simulation data server or simulation input for testing data bindings

🛠️ Installation

git clone https://github.com/NarkisShallev/FlightSimulator-Interpreter.git  
cd FlightSimulator-Interpreter  
mkdir build && cd build  
cmake ..  
make

Once built, you can run the interpreter executable (for example ./interpreter if named so), passing a script file or using interactive mode.

./interpreter script.txt  
# or  
./interpreter  
> var x = 5  
> print x

If your script uses data server bindings, make sure the simulated server is running or data input is being provided.

🗂️ Usage

Here is a small snippet of what a script might look like:

🏗️ Architecture & Design

• Command Pattern: Each command in the language is implemented as a class deriving from a base Command interface (e.g., PrintCommand, WhileCommand, OpenDataServerCommand).
• Expression Handling: Expressions are parsed into expression trees and evaluated at runtime.
• Data Binding: The interpreter supports binding simulation variables (for example, flight instrumentation values) to local names; updates propagate accordingly.
• Server/Client Simulation: The project includes modules to simulate a data server (sending flight simulation values) and a client writer (receiving/writing values).
• Parser & Text Analyzer: Text input (script files or interactive lines) is analyzed, tokenized, parsed into commands and expressions, then executed sequentially.
• Modular Layout: Files and components are organized into intuitive modules: Commands, Expression, DataBinds, DataReaderServer, DataWriterClient, etc.
