rename_identifier

Refactor JavaScript/TypeScript code by renaming identifiers intelligently across files. Ensures accuracy by excluding strings and comments. Preview changes before applying.

Instructions

Intelligently rename all occurrences of an identifier throughout the code. Avoids renaming in strings/comments.

Examples: • Refactor function names: rename_identifier('fetchData', 'fetchUserData') • Improve variable names: rename_identifier('data', 'userData') • Update class names: rename_identifier('Manager', 'UserManager') • API consistency: rename_identifier('getUserInfo', 'fetchUserInfo') • Preview first: rename_identifier('oldName', 'newName', {preview: true}) • Legacy code update: rename_identifier('XMLHttpRequest', 'fetch')

Input Schema

Name	Required	Description
`newName`	Yes	New identifier name (should be valid JavaScript identifier)
`oldName`	Yes	Current identifier name to find and replace
