Halstead Metrics

This project provides a tool to analyze source code and calculate Halstead metrics. Halstead metrics are a set of software metrics introduced by Maurice Halstead to measure the complexity of a program.

Features

• Supports multiple programming languages including C#, Java, JavaScript, Python, and Ruby.
• Calculates various Halstead metrics such as:
  • Number of distinct operators (N1)
  • Number of distinct operands (N2)
  • Total number of operators (n1)
  • Total number of operands (n2)
  • Program vocabulary (N)
  • Program length (n)
  • Calculated program length (Np)
  • Calculated program volume (V)
  • Calculated program difficulty (D)
  • Calculated program effort (E)
  • Calculated program time (T)
  • Calculated program bugs (B)

Usage

To use the tool, run the main.go file with the -filepath flag pointing to the source code file you want to analyze. For example:

go run main.go -filepath path/to/sourcecode.ext

Example

Here is an example of how to use the tool to analyze a Python file:

go run main.go -filepath Dataset/PalindromeChecker.py

Requirements

• Go 1.23.2 or higher

Installation

1. Clone the repository:

2. Navigate to the project directory:

   cd halstead-metrics

3. Run the tool:

   go run main.go -filepath path/to/sourcecode.ext
