Basic Renaming

Function Renaming

Rename a function across your entire codebase:

# Generate a plan and review
renamify plan getUserName fetchUserProfile

# Apply the changes
renamify apply

Or use the fast-path:

# Plan, preview, confirm, and apply in one command
renamify rename getUserName fetchUserProfile

What Gets Changed

JavaScript/TypeScript files:

// Before
function getUserName(id) { ... }
const name = getUserName(userId);
export { getUserName };

// After
function fetchUserProfile(id) { ... }
const name = fetchUserProfile(userId);
export { fetchUserProfile };

Python files:

# Before
def get_user_name(user_id): ...
name = get_user_name(id)

# After
def fetch_user_profile(user_id): ...
name = fetch_user_profile(id)

Files and directories:

• utils/getUserName.js → utils/fetchUserProfile.js
• tests/get_user_name.test.py → tests/fetch_user_profile.test.py

Variable Renaming

Rename variables and constants:

renamify rename apiKey secretKey

What Gets Changed

Various naming conventions:

// Before
const apiKey = "...";
const API_KEY = process.env.API_KEY;
const api_key = config.api_key;

// After
const secretKey = "...";
const SECRET_KEY = process.env.SECRET_KEY;
const secret_key = config.secret_key;

Component Renaming

Rename React/Vue components:

renamify rename UserCard ProfileCard

What Gets Changed

Component files:

• components/UserCard.tsx → components/ProfileCard.tsx
• components/user-card.vue → components/profile-card.vue

Component usage:

// Before
import UserCard from './UserCard';
<UserCard user={currentUser} />

// After
import ProfileCard from './ProfileCard';
<ProfileCard user={currentUser} />

Class Renaming

Rename classes across multiple files:

renamify rename DatabaseManager DataManager

What Gets Changed

# Before
class DatabaseManager:
    def __init__(self): ...

db_manager = DatabaseManager()

# After
class DataManager:
    def __init__(self): ...

data_manager = DataManager()

Safe Undo

If you make a mistake, easily undo:

# See recent operations
renamify history

# Undo the last operation
renamify undo abc123-20241201-143022

# Or redo if you change your mind
renamify redo abc123-20241201-143022
