Generate list index

1.js

// separator is what to put between each link. Examples:
// - New line: '\n'
// - Comma: ', '
// - Pipe: ' | '
const separator = '\n';

// The link for the URL. It must contain a slash at the end.
// You cannot use the [List123] links.
const listURL = 'https://rateyourmusic.com/list/echance/a-state-of-trance-1/';

// format controls the text of the link itself. Examples:
// - Title or artist name: $title
// - Release name: $subtitle
// - Page number: $page
// - Smallest/largest item numbers on page: $min or $max
// - Item contents: $body
// - Total number of pages: $pages
const format = '$title - $subtitle ($page)';

// You will need to set this to the page size of the list so the offsets are
// correct.
const pageSize = 50;

// Set to true if the list is reversed. This affects $min and $max but also puts
// the final result in reverse order to match the list.
const reversed = true;
