Adds a fully functional "Fork" button to your own Gist.

Fork your own Gist

This is a script that adds a fully functional Fork button to your own Gist.

If a Fork button is already present in the page, this bookmarklet will set focus to it instead of adding another one.

The change is temporary and the button will disappear as soon as you navigate away from that Gist (clicking the Fork button does this for you as well). Meaning you will have to run the script every new page load.

Firefox

Copy the contents from bookmarklet.js, open Scracthpad (Ctrl+F4), paste it there. Back in browser, swwitch to tab with your Gist you want to fork. Back in Scratchpad, "Run" it. Save and/or bookmark the Scratchpad file for future use.

An addon to do this automatically is available. It is called ghForkable and is found at AMO here.

In browsers that support bookmarlets (IE, Google Chrome, Opera)

To run this bookmarklet, switch to tab with your Gist you want to Fork. Then copy paste the Closure Compiler optimized version provided below into you URL bar and hit enter.

Note for Firefox Firefox does not allow bookmarklets, meaning you cannot paste this in your URL bar, and thus you cannot bookmark it. You have to open the scratchpad (Shift + F4) and then paste it there and run it. Can copy and paste either version, bookmarklet.js or closure-compiled.js to scratchpad. You can save the scratchpad file and reuse it, just like a bookmark.

bookmarklet.js

javascript: (function () {
	var fork, present, star, button, form, forks, count;
	$('.pagehead-actions li').each(function () {
		var action = $(this).find('form').attr('action');
		if (action) {
			switch (action.split('/').pop()) {
			case 'fork':
				fork = $(this);
				present = true;
				break;
			case 'star':
				star = this;
				break;
			case 'unstar':
				star = this;
				break;
			}
		}
	});
	if (!fork) {
		if (!star) {
			alert('No "Star" or "Unstar" button on this page. Leading me to believe this is not a page that can be forked.');
			return;
		}
		fork = $(star).clone();
	}
	button = fork.find('.minibutton');
	if (present) {
		button.focus();
		return;
	}
	form = fork.find('form');
	form.attr('action', form.attr('action').split('/').map(function (a) {
		return a == 'star' || a == 'unstar' ? 'fork' : a;
	}).join('/'));
	button.html('<span class="octicon octicon-git-branch"></span>Fork');
	forks = $('.counter').filter(function () {
		var href = $(this).parent().attr('href');
		return href ? href.split('/').some(function (a) {
			return a === 'forks';
		}) : false;
	});
	count = fork.find('.social-count');
	count.html(forks.text() || 0);
	count.attr('href', forks.parent().attr('href'));
	if (count[0].tagName == 'SPAN') {
		count.addClass('js-social-count'); //if its a span it doesnt have this class
		count.replaceWith(function () {
			var attrs = {};
			$.each(this.attributes, function (index, attr) {
				attrs[attr.name] = attr.value;
			});
			return $('<a>', attrs).append(count.contents().clone(true, true));
		});
	}
	$('.pagehead-actions li:last').parent().append(fork);
}());

closure-compiled.js

javascript:(function(){var e,g,d,a,c,f,b;$(".pagehead-actions li").each(function(){var h=$(this).find("form").attr("action");if(h){switch(h.split("/").pop()){case"fork":e=$(this);g=true;break;case"star":d=this;break;case"unstar":d=this;break}}});if(!e){if(!d){alert('No "Star" or "Unstar" button on this page.

the original had some issues:

1. did not work when if you the page you are trying to run it on was already starred by you
2. if there were 0 stars but were fork count > 0, the fork count would not be a clickable link (note: if there are 0 forks, the link created will still not be clickable)

Help - I'm trying to follow your instructions in Chrome, but it's not working? My gist has not been starred or forked previously.

Not working for me on Firefox 36. :( I had a user style installed for GitHub, but after I disabled it and restarted, it still didn't work. I have NoScript installed; would that be a problem? It doesn't show as blocking anything. I tried both installing the addon and pasting into the URL.

Okay, got it to work by pasting it into the Scratchpad. Thanks!

A typo in Firefox section: 'swwitch' -> 'switch'

Thanks!

This doesn't work anymore, does it? 😕

Did not work as intended for me. Instead saw a second Star button added.

Nope. Doesn't work for me as well. (using Google Chrome v55.0)

You can’t perform that action at this time.

Don't know about you but jQuery is not present in my github gists page.

Yeah, it seems to not be possible at all any more anyway.
