Better Replace-On-Save

Replace-on-save with better VSCode integration.

This extension adds the ability to run regex replacements as a code action (it does not strictly have to be "on save")

eg.

{
  // ...
  "editor.codeActionsOnSave": {
    "source.applyReplacements": true
  },
}

Features

General Features

• source.applyReplacements CodeActions provider which can be used in the editor.codeActionsOnSave setting
• Command better-replace-on-save.applyReplacements ("Apply Replacements") that can be executed from the command palette
• Language-specific replacements that only apply to files of specified languages
• Comprehensive settings documentation with VS Code IntelliSense support

ID-Based Replacements (New in 0.2.0)

• Configure replacements with unique IDs to apply them individually
• Each ID-based replacement gets its own code action that can be used in editor.codeActionsOnSave
• Command better-replace-on-save.applySpecificReplacement ("Apply Specific Replacement") to run a single replacement by ID
• Context-aware language filtering:
  • ID-based replacements respect language filters when run as code actions (on save)
  • ID-based replacements ignore language filters when run as direct commands (giving you flexibility to override language constraints when needed)

Extension Settings

Configure your replacements using the following settings:

// settings.json
{
  // ...
  "betterReplaceOnSave.replacements": [
    {
      "search": "hello",
      "replace": "world"
    },
    {
      "search": "let",
      "replace": "const",
      "languages": [ "typescript", "javascript" ] // Optional
    },
    {
      "id": "convertPrint", // Optional: enables specific replacement functionality
      "search": "print\\(",
      "replace": "logger.info(",
      "languages": [ "python" ] // Optional
    }
  ]
  // ...
}

Applying Specific Replacements on Save

You can configure VS Code to run only specific replacements on save:

{
  "editor.codeActionsOnSave": {
    // Apply a specific replacement with ID "convertPrint"
    "source.applyReplacements.convertPrint": true
  }
}

Applying Specific Replacements Manually

To apply a specific replacement manually:

1. Open the command palette (Ctrl+Shift+P or Cmd+Shift+P on Mac)
2. Search for "Apply Specific Replacement"
3. Select the replacement by ID from the dropdown

This is particularly useful when you want to apply a replacement regardless of language restrictions.
