Installation

1. Install from VSCode Marketplace or load the extension from VSIX.
2. Open a supported language file mentioned in features
3. Ensure TypeScript checking (checkJs) is enabled for JavaScript/TypeScript for undeclared variable detection (optional).

{
  "compilerOptions": {
    "checkJs": true,
    "noEmit": true,
    "target": "ES2020"
  },
  "include": ["**/*.js", "**/*.ts"]
}

Usage

1. Typo Detection:

   • Misspelled keywords or undeclared variables are automatically highlighted with red strikethrough.
   • Hover or click CodeLens to see replacement suggestions.

2. Fixing Typos:

   • Click a CodeLens suggestion to replace the typo.
   • Strikethrough decoration and CodeLens update immediately.

3. Manual Refresh:

   • Run Refresh Keyword Suggestions from the Command Palette or press Ctrl+Alt+R to manually refresh suggestions and decorations.

Configuration

No extra configuration is needed. Optional:

• Add custom keywords to the keywords array in the extension source.

  consol.log("Hello " + name); // ❌ 'functon' and 'consol' highlighted
}

• Suggestions:

  • Replace 'functon' → 'function'.
  • Replace 'consol' → 'console'.

Tech Stack

• VSCode Extension API
• TypeScript & JavaScript
• Levenshtein distance (fast-levenshtein)
• Regex & CodeLens for inline suggestions
• Symbol caching and debounced updates for performance

Known Limitations

• Best used with plain files and modern language modules.
• Undeclared variable detection depends on TypeScript or ESLint configuration.
• Cross-file variable tracking is not yet supported.
• Scoped variable name recommendation is yet to come.
