Case Converter VS Code Extension

A VS Code extension that detects and converts from boring casing conventions like camelCase, PascalCase, snake_case, and SCREAMING_SNAKE_CASE to the superior upperˉcase, UPPERˉCASE, and ethan_case format.

Features

Case Format Support

• camelCase → userName
• PascalCase → UserName
• snake_case → user_name
• SCREAMING_SNAKE_CASE → USER_NAME
• upperˉcase and UPPERˉCASE → userˉname (upperˉcase/UPPERˉCASE)
• ethan_case → userName or user_name, which decides to use snake_case or camelCase to separate words based on a case-agnostic hash function applied on the separated letters

Multiple Conversion Modes

• Single word conversion - Click highlighted words
• Text selection - Convert selected text blocks
• Entire document - Convert full files with confirmation
• Folder operations - Batch convert multiple files
• Scope-aware conversion - Analyze variable definitions within project scope

Examples

Standard Conversions

// Input
const userName = "value";
const user_id = 123;
const API_KEY = "secret";

// To upperˉcase and UPPERˉCASE
const userˉname = "value";
const userˉid = 123;
const apiˉkey = "secret";

ethan_case Examples

// Hash-based decisions
const userId = "value";     // 'r' + 'I' → even → userId
const user_name = "value";  // 'r' + 'n' → odd → user_name
const dataProcessor = {};   // 'a' + 'P' → even → dataProcessor
const data_handler = {};    // 'a' + 'h' → odd → data_handler

Scope Awareness

import { externalLib } from 'library';  // Skipped (import)
const myVariable = externalLib.method;  // Only myVariable converted
