🚀 Quick Start

Automatic Installation

Snippets are automatically available when you open the AudioLab workspace in VS Code.

Manual Installation

If snippets aren't loading:

  1. Copy snippet files to VS Code user snippets directory:

Windows: 

$dest = "$env:APPDATA\Code\User\snippets"
Copy-Item cpp.json $dest
Copy-Item cmake.json $dest
Copy-Item markdown.json $dest

macOS/Linux: 

cp cpp.json ~/Library/Application\ Support/Code/User/snippets/
cp cmake.json ~/Library/Application\ Support/Code/User/snippets/
cp markdown.json ~/Library/Application\ Support/Code/User/snippets/

  1. Restart VS Code

  2. Verify installation:

  3. Create a new .cpp file
  4. Type audproc and press Tab
  5. Should expand to AudioProcessor class template

Snippets are already configured in .vscode/settings.json:

{
  "vscode.snippets.suggestSnippets": "top",
  "editor.snippetSuggestions": "top"
}

📖 Usage Guide

Basic Workflow

  1. Start typing trigger prefix (e.g., audproc)
  2. Select snippet from IntelliSense dropdown
  3. Press Tab to insert
  4. Fill placeholders:
  5. Tab: Next placeholder
  6. Shift+Tab: Previous placeholder
  7. Esc: Cancel snippet mode

Example: Creating an Audio Processor

  1. Type audproc → Press Tab
  2. Type class name → Press Tab
  3. Fill in initialization code → Press Tab
  4. Fill in processing algorithm → Done!

💡 Advanced Features

Multi-Cursor Editing

Many snippets support multi-cursor for repeated patterns:

// Type: dsp-filter
// Result: Multiple filters in parallel
FilterName filter1;
FilterName filter2;
FilterName filter3;

Nested Snippets

Combine snippets for complex structures:

  1. Insert audproc (processor class)
  2. Inside process(), insert dsp-filter (add filter)
  3. Inside private:, insert param-smooth (add parameter)

Variable Transformations

Some snippets use VS Code variables:

  • ${TM_FILENAME}: Current filename
  • ${CURRENT_YEAR}: Current year
  • ${CURRENT_DATE}: Current date

Example in header snippet: 

/**
 * @file MyProcessor.hpp  // Auto-filled
 * @date 2025-01-04       // Auto-filled
 */

🔧 Customization

Adding Custom Snippets

Edit snippet files directly:

{
  "My Custom Snippet": {
    "prefix": "mysnip",
    "body": [
      "void ${1:functionName}(${2:params}) {",
      "    ${0:// Implementation}",
      "}"
    ],
    "description": "My custom function"
  }
}

Modifying Existing Snippets

  1. Open snippet file (e.g., cpp.json)
  2. Find snippet by prefix
  3. Edit body array
  4. Save (changes apply immediately)

Snippet Placeholder Syntax

Syntax Meaning Example
${1:name} Tab stop 1 with placeholder ${1:MyClass}
${2} Tab stop 2 (empty) ${2}
${0} Final cursor position ${0:// Done}
$TM_FILENAME Current filename $TM_FILENAME
${1\|a,b,c\|} Choice dropdown ${1\|VST3,AU,AAX\|}

audproc      📄 AudioProcessor Class
audio_buffer  🔧 Variable
AudioEngine   📦 Class

Configuration

Optimize snippet visibility in settings.json:

{
  // Show snippets at top of suggestions
  "editor.snippetSuggestions": "top",

  // Enable snippet completions
  "editor.suggest.snippetsPreventQuickSuggestions": false,

  // Show snippet icons
  "editor.suggest.showSnippets": true,

  // Tab completion
  "editor.tabCompletion": "on"
}

Trigger Suggest Manually

If IntelliSense doesn't show snippets:

  • Windows/Linux: Ctrl+Space
  • macOS: Cmd+Space

🏆 Best Practices

DO ✅

  1. Learn Top 10 Snippets - Focus on most-used patterns
  2. Customize for Your Workflow - Adapt snippets to your style
  3. Use Consistent Naming - Keep trigger prefixes logical
  4. Tab Through Placeholders - Don't manually click each field
  5. Combine Snippets - Build complex code from simple blocks
  6. Create Project Snippets - Add domain-specific patterns
  7. Review Generated Code - Ensure snippet output matches intent

DON'T ❌

  1. Don't Over-Snippet - Not everything needs a snippet
  2. Don't Skip Understanding - Know what the snippet does
  3. Don't Forget to Update - Keep snippets current with standards
  4. Don't Ignore Placeholders - Fill in all required values
  5. Don't Paste Raw Snippets - Use the snippet system

🛠️ Troubleshooting

Snippets Not Appearing

Problem: Typing trigger doesn't show snippet

Solutions:

  1. Check file type: Snippets are language-specific
  2. cpp.json → .cpp, .hpp, .h files
  3. cmake.json → CMakeLists.txt, .cmake files

  4. markdown.json → .md files

  5. Verify snippet is loaded:

  6. Ctrl+Shift+P → "Insert Snippet"

  7. Check if snippet appears in list

  8. Check settings: 

    {
  "editor.quickSuggestions": {
    "other": true,
    "comments": false,
    "strings": false
  }
}

  9. Restart VS Code

Snippet Expands Incorrectly

Problem: Generated code has wrong indentation or format

Solutions:

  1. Check tab settings: 

    {
  "editor.insertSpaces": true,
  "editor.tabSize": 4
}

  2. Format after insertion: Shift+Alt+F

  3. Edit snippet to match your style

Placeholders Not Working

Problem: Can't tab through placeholders

Solutions:

  1. Ensure you're in snippet mode (cursor shows multi-line)
  2. Don't click outside snippet area
  3. Press Tab (not arrow keys) to navigate
  4. Check keybinding for jumpToNextSnippetPlaceholder

Snippet Conflicts

Problem: Wrong snippet expands for trigger

Solutions:

  1. Make triggers unique: Prefix with category
  2. al- for AudioLab
  3. dsp- for DSP

  4. test- for testing

  5. Use longer triggers: audproc vs proc

  6. Scope snippets: Limit to specific file types

📈 Performance Tips

Snippet Loading

  • User snippets: Load globally (slower startup)
  • Workspace snippets: Load per-workspace (faster)
  • Extension snippets: Lazy loaded (recommended)

Large Snippet Files

If snippets are slow:

  1. Split into categories:
  2. cpp-audio.json (audio-specific)

  3. cpp-general.json (general C++)

  4. Remove unused snippets

  5. Use snippet extensions for rarely-used snippets

🔗 Integration with Other Tools

GitHub Copilot

Snippets complement Copilot:

  • Snippets: Structured boilerplate
  • Copilot: Context-aware completion

Use both: 1. Insert snippet for structure 2. Let Copilot fill implementation

Vim/Emacs Emulation

Snippets work with vim/emacs modes:

  • Vim: Insert mode → Type trigger → Tab
  • Emacs: Type trigger → M-/

Live Share

Snippets sync in Live Share sessions - all collaborators see expansions

🌟 Advanced Patterns

Snippet Chains

Create workflows by chaining snippets:

Example: New Audio Module

  1. project → CMake project structure
  2. allib → Library target
  3. audproc → Processor implementation
  4. altest → Test file
  5. readme → Documentation

Template Projects

Combine snippets into project templates:

Filter Plugin Template: 

# Create structure
mkdir my-filter && cd my-filter
# Use snippets to populate:
# - CMakeLists.txt (alplug)
# - src/Processor.hpp (audproc)
# - src/Filter.hpp (dsp-filter)
# - tests/test.cpp (test-case)
# - README.md (readme)

Snippet Macros

Create keyboard shortcuts for common snippet sequences:

keybindings.json: 

{
  "key": "ctrl+alt+a",
  "command": "editor.action.insertSnippet",
  "args": { "name": "AudioProcessor Class" }
}
