Not quite the same functionality but on that page you can click the drop-down on the search bar and "Add GitHub". Then the github command line is one of the options for search providers alongside Google, Wikipedia etc. If you select it as the default, you can Ctrl-K up to the search bar and type a command without leaving the keyboard.
Also (and I'm not sure how useful this is) you can select some text, right-click it and execute it as a GitHub command.
Adding a keyword for that field uses the following URL: https://github.com/search?q=&type=Everything&repo=... which ends up as a regular search.
So typing "g @mojombo" doesn't bring me to his profile but rather triggers a regular search.
However github would be better served if the github.com put the tab focus right inside the command bar. That way their would be no need for /launch at all...
I wish they simply fixed their regular code search. It has never worked and is one of the features I miss. Russ Cox's Google Code Search was an excellent example of how this should look like, to bad it's gone as well.
I hate how it shows all freaking forks. Say I wanted to look for a theme for a particular piece of software. I'd have to wade trough the countless forks of the software in question, occasionally actually seeing a theme listed. It's terribru.
It's not quite the command bar, but GitHub's search box uses OpenSearch and Chrome picks it up. You should be able to type `github.com`, hit tab, and then search GitHub.
I really like the new command bar. And my initial thought was how awesome a browser integration would be. So, I just started coding a small Chrome extension and here it is:
It's far from complete and only supports a subset of GitHub's command bar and not the same ranking logic. But it already does a decent job for repositories and users. As soon as I have more time I will add more features.
Btw I'm sure it could be done for Firefox and Safari too.
Looks like they're really going "all-in" on the CLI for web app concept. I'd expect to start seeing this type of interface really taking off for a lot of developer facing services. What's old is new again...
Could GitHub just make gitgub.com/foo work in exactly the sane way as putting "foo" in the command bar? It wouldnt have the same autocomplete, but it would be much faster.
Does anyone know how to initiate a web compare between to branches using this thing? If I could have that + Alfred (or whatever launch bar / cli one uses) that would be amazing.
I was looking into this briefly, it seems it would all be pretty straightforward apart from the fact that you need to be authenticated to access the JSON endpoints, I'm not sure how that would work as an Alfred extension.
Then I can use the GitHub launcher without having to touch the mouse:
