Using the Gist below you can easily import other Gists to your Unity project just copying the URL from browser:

Code

	using System;
	using System.IO;
	using System.Linq;
	using System.Net;
	using System.Text.RegularExpressions;
	using UnityEditor;
	using UnityEngine;

	/// <summary>
	/// Gist importer.

	[InitializeOnLoad]
	public static class GistImporter
	{
	const string GistsFolder = "Gists";
	static readonly Regex _getGistUrlInfoRegex = new Regex("https://gist.github.com/(?<owner>.+)/(?<gistId>[a-z0-9]+)", RegexOptions.IgnoreCase \| RegexOptions.Compiled);
	static readonly Regex _getDescriptionRegex = new Regex(@"\<title\>(?<description>.+)\</title\>", RegexOptions.IgnoreCase \| RegexOptions.Compiled);
	static readonly Regex _getFileUrlRegex = new Regex("href=\"(?<url>.+/raw/[a-z0-9\\./\\-]+)\"", RegexOptions.IgnoreCase \| RegexOptions.Compiled);

	[MenuItem("Tools/Import Gist")]
	static void ImportGist()
	{
	var gistUrl = EditorGUIUtility.systemCopyBuffer;

	try
	{
	using (var client = new WebClient())
	{
	var gistPageContent = client.DownloadString(gistUrl);

	// Extract the files raw urls.
	var filesMatches = _getFileUrlRegex.Matches(gistPageContent);

	if (filesMatches.Count > 0)
	{
	var infoMatch = _getGistUrlInfoRegex.Match(gistUrl).Groups;
	var gistOwner = infoMatch["owner"].Value;
	var gistId = infoMatch["gistId"].Value;
	var rawUrls = filesMatches
	.OfType<Match>()
	.Select(m => $"https://gist.github.com{m.Groups["url"].Value}")
	.OrderByDescending(u => u.EndsWith(".cs", StringComparison.OrdinalIgnoreCase))
	.ToArray();

	var destinationFolder = Path.Combine(Application.dataPath, GistsFolder, gistOwner, $"{Path.GetFileNameWithoutExtension(rawUrls.First())} ({gistId})");

	// Downloads and write the Gist files.
	for (var i = 0; i < rawUrls.Length; i++)
	{
	var rawUrl = rawUrls[i];
	var filename = Path.GetFileName(rawUrl);

	EditorUtility.DisplayProgressBar("Importing Gist...", filename, i / (float)filesMatches.Count);
	DownloadFile(client, rawUrl, destinationFolder, filename);
	}

	EditorUtility.ClearProgressBar();
	WriteReadme(gistUrl, gistPageContent, destinationFolder);
	}
	else
	Debug.LogWarning($"No files found for Gist '{gistUrl}'.");
	}
	}
	finally
	{
	EditorUtility.ClearProgressBar();
	}
	}

	[MenuItem("Tools/Import Gist", true)]
	static bool ValidateImportGist()
	{
	return _getGistUrlInfoRegex.IsMatch(EditorGUIUtility.systemCopyBuffer);
	}

	static void DownloadFile(WebClient client, string url, string destinationFolder, string filename)
	{
	var fileContent = client.DownloadString(url);

	// Is an editor script?
	if (fileContent.IndexOf("using UnityEditor;", StringComparison.OrdinalIgnoreCase) > -1)
	destinationFolder = Path.Combine(destinationFolder, "Editor");

	Directory.CreateDirectory(destinationFolder);
	File.WriteAllText(Path.Combine(destinationFolder, filename), fileContent);
	}

	static void WriteReadme(string gistUrl, string gistPageContent, string folder)
	{
	var description = _getDescriptionRegex.Match(gistPageContent).Groups["description"].Value;
	var readmePath = Path.Combine(folder, "readme.txt");
	File.WriteAllText(readmePath, $"{description}\n\nUrl: {gistUrl}\nDate: {DateTime.Now:dd/MM/yyyy HH:mm}\n\nImported using Gist Importer (http://diegogiacomelli.com.br/unitytips-gist-importer).");

	// Selects the readme file on project window.
	AssetDatabase.Refresh();
	var readmeAsset = AssetDatabase.LoadAssetAtPath<UnityEngine.Object>($"Assets{readmePath.Replace(Application.dataPath, string.Empty)}");
	Selection.activeObject = readmeAsset;
	EditorGUIUtility.PingObject(readmeAsset);
	}
	}
