• Sample Code: Load example code for any supported language

Understanding Syntax Highlighting

Syntax highlighting (also called code highlighting) is a feature that displays source code in different colors and fonts according to the category of terms. This makes code easier to read and understand by visually distinguishing:

• Keywords: Reserved words in the language (e.g., if, function, class)
• Strings: Text literals enclosed in quotes
• Comments: Explanatory text that doesn't execute
• Variables: Identifiers for data storage
• Functions: Named blocks of code
• Numbers: Numeric literals
• Operators: Symbols for operations (+, -, *, /, etc.)

Example

Here's how JavaScript code looks in the source code viewer:

function greet(name) {
    return `Hello, ${name}!`;
}

console.log(greet('World'));

With syntax highlighting, keywords like function and return are colored differently from strings, making the code structure immediately clear.

Best Practices

• Select the Correct Language: Choose the appropriate programming language for accurate syntax highlighting
• Use File Upload: For large code files, use the file upload feature instead of pasting
• Adjust Font Size: Use the font size slider to find the most comfortable viewing size
• Review Formatting: The viewer maintains your code structure while adding visual formatting
• Copy When Needed: Use the copy button to quickly copy formatted code for use elsewhere

Use Cases

Code Review

Use the source code viewer to review code files with proper syntax highlighting, making it easier to spot errors, understand structure, and analyze code quality.

Documentation

View code snippets in a formatted, readable way when preparing documentation, tutorials, or blog posts. The syntax highlighting makes code examples more professional and easier to understand.

Learning

Students and beginners can use the viewer to see how different programming languages structure code, with visual cues helping to understand syntax and language features.

Code Analysis

Analyze code structure and formatting by viewing code in a clean, organized format. The syntax highlighting helps identify different code elements and their relationships.

Technical Details

The Source Code Viewer uses the Ace Editor library for syntax highlighting and code display. It provides:

• Real-time syntax highlighting based on language selection
• Multiple color themes (GitHub theme for input, Monokai for viewer)
• Line numbers and gutter display
• Active line highlighting
• Read-only viewer mode to preserve formatting
