What programming languages are supported?

The code viewer supports 180+ programming languages including JavaScript, TypeScript, Python, Java, C/C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, Scala, Haskell, Perl, R, Shell/Bash, PowerShell, HTML, CSS/SCSS/LESS, SQL, JSON, XML, YAML, Markdown, and many more. Modern frameworks like React (JSX), Vue, Angular templates, and language features (ES2023, Python 3.12, Java 21) are supported with accurate syntax highlighting.

Is my source code safe and private?

Yes, absolutely. All code parsing, syntax highlighting, rendering, and searching happens entirely in your browser using Prism.js - a client-side JavaScript library. Your source code never leaves your device - there are no server uploads, database storage, or external API calls. Perfect for proprietary code, trade secrets, internal scripts, API keys, authentication logic, and confidential implementations.

Can the viewer detect the programming language automatically?

Yes! The viewer automatically detects programming languages from file extensions (.js → JavaScript, .py → Python, .java → Java, .ts → TypeScript, .cpp → C++, etc.). It handles both common and uncommon extensions (e.g., .jsx, .tsx, .mjs, .cjs for JavaScript variants) for accurate syntax highlighting without requiring manual language selection.

What's the maximum code file size supported?

The viewer supports code files up to 50MB. While most source code files are small ( 10MB) may take a few seconds to parse and highlight depending on language complexity.

Can I view minified JavaScript or compressed code?

Yes! The viewer displays minified code (single-line, no whitespace) with syntax highlighting. While minified code remains compressed (we don't auto-format/beautify to preserve exact source), syntax highlighting makes it much more readable by color-coding strings, keywords, and structures. For better readability, consider beautifying code first with a formatter before viewing.

Does the viewer work for code snippets from documentation or tutorials?

Yes, perfectly! The viewer is ideal for reviewing code snippets from documentation, tutorials, GitHub gists, StackOverflow answers, and online courses. Just copy the code into a .js, .py, or appropriate file extension and upload it. Great for studying example code, understanding library usage, or analyzing solutions with proper syntax highlighting.

Can I search for specific functions or variables in my code?

Yes! Use the search bar to find function names, variable declarations, class definitions, API calls, imports, or any text pattern in your code. Search highlights all matches with navigation buttons for next/previous results. Perfect for understanding code structure, finding where functions are defined, or locating specific logic in large files.

Can I copy code from the viewer?

Yes! Select and copy any code using your mouse or keyboard (Ctrl+A to select all, Ctrl+C to copy). Copy entire files, specific functions, or individual lines. Line numbers (if displayed) are not included when copying - only the actual code content. Paste into IDEs, text editors, documentation, or code sharing platforms.
