Int-Maxer Extension for VS Code

Author: Palamarchuk Arseniy, ITMO, M3105

Int-Maxer is a Visual Studio Code extension that automatically upgrades all integer variable types in your C++ files to their largest counterparts. For example, it transforms int8_t into int64_t and uint16_t into uint64_t. This tool is perfect for developers who need to ensure maximum data capacity for integer types.

Features

• Automatically replace all occurrences of smaller integer types with their largest equivalents:
  • int8_t → int64_t
  • uint8_t → uint64_t
  • int16_t → int64_t
  • uint16_t → uint64_t
  • int32_t → int64_t
  • uint32_t → uint64_t
• Works seamlessly with C++ files.
• Adds a button in the status bar to activate the transformation with a single click.

Requirements

• Visual Studio Code version 1.95.0 or higher.
• Node.js installed for development or debugging purposes.

Installation

1. Clone the repository:

   git clone https://github.com/your-repo/int-maxer.git
   cd int-maxer

2. Install dependencies:

   npm install

3. Compile the extension:

   npm run compile

4. Open the project folder in Visual Studio Code.
5. Press F5 to launch the extension in a new Extension Development Host window.

Usage

1. Open a C++ file in Visual Studio Code.
2. Trigger the extension using one of the following methods:
   • Open the Command Palette (Ctrl+Shift+P), type Maximize Variable Types (C++), and press Enter.
   • Click the Maximize Types button in the status bar (bottom-right corner of the editor).
3. All eligible types in the file will be replaced with their larger equivalents.

Development

Folder Structure

• src/: Contains the TypeScript source code for the extension.
• out/: The compiled JavaScript code generated by TypeScript.
• package.json: Configuration and metadata for the extension.

Scripts

• Compile TypeScript:

  npm run compile

• Watch for TypeScript changes:

  npm run watch

Debugging

1. Open the project in Visual Studio Code.
2. Go to the Run and Debug panel.
3. Start debugging with the Launch Extension configuration.

Limitations

• Works only with standard fixed-width integer types (int8_t, uint8_t, etc.).
• Does not handle custom integer typedefs or unusual naming conventions.
