Ebyte Spark Java Compiler CLI

A simple command-line tool to compile Java source files quickly using Node.js and the system's installed Java compiler (javac). Designed for educational use, automation, and integration in Java learning environments.

✨ Features

• ✅ Check if Java are installed using jcheck
• ✅ Compile .java files from the command-line using jrun fileName.java
• ✅ Clear output with helpful logs
• ✅ Works cross-platform (Windows/Linux/macOS)
• ✅ Lightweight and fast!

📦 Installation

Make sure you have Node.js installed. Then install globally using:

npm install -g ebyte-spark-j-c

You can also install locally in a project:

npm install ebyte-spark-j-c

🚀 Usage

From the command-line

To compile a Java source file from your terminal:

jrun HelloWorld.java

If javac is not found or Java is not installed, you'll see a clear error message.

Example Output

✅Compiling Java file: main.java ✅Running from directory: C:\Users\Ebed.Dev\Desktop\Open Source App Lib\test package ✅Hello World

If there is a syntax error:

!!!!! Compilation failed:
Test.java:3: error: ';' expected
    System.out.println("Hello World")
                                   ^
1 error

🧑‍💻 As a Node.js Module (API Usage)

You can import and use the compiler in your own Node.js scripts.

const { compileJava } = require('ebyte-spark-j-c');

compileJava('Test.java', (err, stdout, stderr) => {
  if (err) {
    console.error('Compilation failed:', stderr);
  } else {
    console.log('Compiled successfully!');
  }
});

🔧 CLI Check for Java Installation

The command also checks if Java and jcheck are installed and shows their version. If not, you will see:

!!!!! Java is not installed or not found in the PATH.
Error detail: spawn java ENOENT
