Language Detection

Automatic Detection

Osmynt automatically detects the language based on:

File extension - Primary detection method
File content - Shebang lines and language signatures
VS Code language mode - Current editor language
Project configuration - .gitattributes and language settings

Manual Override

You can manually specify the language:

Select your code in the editor
Right-click and choose "Share Selected Code"
In the sharing dialog, select the correct language
Share with the specified language

Performance Optimization

Large Files

Chunking - Large files are automatically chunked
Streaming - Real-time streaming for large code blocks
Compression - Automatic compression for network efficiency
Caching - Local caching for frequently accessed code

Network Optimization

Delta updates - Only changed portions are transmitted
Compression - Gzip compression for network efficiency
Batching - Multiple operations are batched together
Connection pooling - Efficient connection management

Troubleshooting Language Support

Common Issues

Incorrect Syntax Highlighting

Problem: Code doesn't highlight correctly Solution:

Check file extension matches the language
Verify VS Code language mode is correct
Manually specify language when sharing

Encoding Issues

Problem: Special characters don't display correctly Solution:

Ensure file is saved with UTF-8 encoding
Check VS Code encoding settings
Verify language supports the character set

Performance Issues

Problem: Slow highlighting for large files Solution:

Break large files into smaller chunks
Use appropriate language settings
Check VS Code performance settings

Language-Specific Issues

JavaScript/TypeScript

JSX not highlighting - Ensure file has .jsx or .tsx extension
Type annotations not working - Check TypeScript version
ES6+ features not recognized - Update VS Code JavaScript settings

Python

Indentation errors - Check tab vs space consistency
Type hints not working - Ensure Python 3.5+ syntax
F-strings not highlighting - Update to Python 3.6+ syntax

C/C++

Modern C++ not working - Check C++ standard setting
Templates not highlighting - Verify C++ extension is installed
Headers not found - Check include path settings

Best Practices

Code Sharing

Use appropriate file extensions - Helps with automatic detection
Include language context - Mention the language in your share title
Share complete functions - Avoid cutting off in the middle of syntax
Use consistent formatting - Follow language-specific style guides

Language Selection

Choose the right language - Manual selection when automatic detection fails
Consider the audience - Team members familiar with the language
Include context - Explain language-specific features being used
Document language requirements - Mention version requirements

Next Steps

Now that you understand language support:

Learn about code sharing - Share code with proper syntax highlighting
Set up team collaboration - Work with teams using different languages
Configure your environment - Customize language settings
Apply code changes - Use diff application with any language
