The muNode class is a hierarchical structure implemented in C++, designed to work with the muParser library. This class is particularly useful for reading and processing text files that contain conditions, expressions, variables, commands, while loops and more.
The muParser library is a lightweight and fast C++ mathematical expression parser. It is designed to perform mathematical computations and evaluations of complex mathematical expressions efficiently. Here's a detailed
The muNode class integrates the muParser library to achieve a comprehensive and robust interpreter for the text files. It combines hierarchical structure management with powerful mathematical expression and condition evaluation capabilities provided by muParser. This integration allows the muNode class to function as a program interpreter capable of executing complicated tasks specified in the input text files.
- C++ Standard Library

- Hierarchical Structure: Nodes can have parent and child nodes.
- Expression Evaluation: Evaluate mathematical expressions using the
muParserlibrary. - Condition Evaluation: Evaluate conditions to control the flow of execution.
- Variable Handling: Add and manage variables in the
muParserinstance associated with the node. - Command Retrieval: Retrieve the command associated with the node.
- Debugging: Print nodes.
- Node Navigation: Navigate through nodes using functions like
getNextNode(),getPreviousNode(), and more.
