Humble Bundle Renamer - jQuery

humble-bundle-renamer.js

/**
 * Humble Bundle Renamer
 *
 * Renames files downloaded from a Humble Bundle downloads page:
 *
 *   - Run the script in the developer tool's JS console
 *   - Copy the generated text, which appears in a box on the page
 *   - Paste this into a text file, within the same folder as your downloaded files
 *   - Save the file, then rename it to "renamer.bat"
 *   - Run the batch script
 *
 * Why this is useful:
 *
 * Files are saved by their server names (eg, "an_interesting_book.pdf"),
 * not their human-readable names ("An Interesting Book.pdf"). 
 * This script gives you the contents of a batch file which renames these
 * downloaded files to their human-readable equivalents.

// Create an array to store our batch file lines
var output = [];

// Build the array
$('.js-all-downloads-holder .whitebox-redux .row').each(function(){
	// Get name
	var name = $(this).find('.gameinfo .title a:first-child').text().trim();
	
	// Replace illegal characters (you can change the "" in the second parameter to whatever you like, as with the first line)
	name = name.replace(":", " -");
	name = name.replace("?", "");
	name = name.replace("*", "");
	name = name.replace("|", "");
	
	// Get filenames & add them to the output array
	$(this).find('.downloads .download .a').each(function() {
		// Get single link URL
		var url = $(this).attr('href');
		
		// Remove the query string from the URL
		var urlQueryIndex = url.indexOf('?');
		var urlSliced = url.slice(0, urlQueryIndex);
		
		// Remove the domain path
		var filename = urlSliced.replace("https://dl.humble.com/", "");
		
		// Get the file extension (".pdf", etc)
		var extensionIndex = urlSliced.lastIndexOf('.');
		var extension = url.slice(extensionIndex, urlSliced.length);
		
		// Batch file renaming convention is "rename [old filename] [new filename]"
		var oldFilename = filename;
		var newFilename = name + extension;
		var batLine = 'rename ' + oldFilename + ' "' + newFilename + '"';
		output.push(batLine);
	});
});

// Create an empty textarea, and usage instructions

// Output the array to the textarea
$.each(output, function(index, value) {

	$('.batch-file-output').append(value + "\n");
