Rename Multiple Files in a Folder

This was inspired by, and is based on a gist by Scriptex, index.js. I have modified it to suit my purpose. I have been downloading books from Zlibrary and the downloaded files have a naming format:

[Author(s)]File_name(z-lib.org).extension

Eg. [WessCoby]_Rename_Multiple_Files_in_a_Folder(z-lib.org).pdf

The Key things i want from this file name string are just the file name and authors(s) And i want to rename each file to:

Filename - Author(s).extension

Eg. Rename Multiple Files in a Folder - WessCoby.pdf

Renaming Process

• Use filePattern to filter for files that need to be renamed
• Use authorPattern to extract Author name(s), and assign to the variable author and remove underscores
• Use bookNamePattern to extract book name and assign to the variable book and remove underscores
• Combine book and author and assign to newName.
• Format: book - @author.extension

Usage

• Create a new folder named Files in the root directory and place the files to be renamed in it.
• In the index file, create your pattern (with a rename method)
• There are two ways to use the pattern:
  • First call RenameFiles.usePattern(patternClass). Then RenameFiles.exec()
  • Second, RenameFiles.exec({ usePattern: patternClass })
    NB: RenameFiles.exec() returns a Promise:
    RenameFiles.exec({ usePattern: patternClass }).then( console.log ).catch( console.error );
• Then use either npm start, node index or node . to run.
