Those of you who are avid readers of my Stack Overflow profile know that I am the creator of JGuitar.com, a popular guitar chord and scale calculator website. I'm also a longtime fan of Apple products. So you can imagine my surprise and delight when I received this message in my inbox this week from a JGuitar user:
Is there a way to select a specific instrument (like ukulele) via the URL - so that I'd have a link that would take me right to chord search for that instrument?
I am starting to mess around with iOS's new shortcut function. They have a shortcut for searching chords on your website, but it defaults to guitar; I'd like to make a ukulele version of the shortcut.
Hold on a sec... Did Apple really integrate their new iOS shortcuts feature with my website? How is it possible I didn't know this was coming? No one from Apple reached out to me. I had eagerly upgraded my iPhone X to iOS 12 earlier that day but hadn't yet discovered "shortcuts". Naturally, I immediately wanted to see this in action.
After a little googling, I learned that in order to add shortcuts, you need to download the Shortcuts App from the Apple App Store.
After installing and launching the Shortcuts app, you're greeted to an empty Library screen. In order to use a shortcut, you need to either create one from scratch or select a pre-made shortcut from the gallery. I clicked on the Gallery icon, scrolled down to the "Tools for Making Music" section and saw the "Guitar Chord Finder" shortcut.
Could this be it? The description didn't mention JGuitar.com. I clicked on it. There were instructions for how to use the shortcut but still no mention of JGuitar.com. When I clicked "show actions" it revealed the "actions" that make up the shortcut and I could finally see the JGuitar.com link in the URL section. Here are the complete actions that make up the Guitar Chord Finder Shortcut.
In a nutshell, the shortcut uses the user's input (a chord symbol) to construct a url to a chord search result page on JGuitar.com and then looks for 200x200px chord diagram images on that page and shows them to the user. The rest of the web page isn't shown.
There are a couple of things I would have done differently in these shortcut actions. Firstly, I would have used an https url instead of http and secondly, I would have made it look for images with a width & height greater than 200px rather than equal to 200px. That would give me the flexibility to boost image resolution without breaking the shortcut. And boosting image resolution is an easy change for me since all the chord diagram images are dynamically generated on the fly and cached.
Now that I had found and understood the feature it was time to take it for a test drive. I added the Guitar Chord Finder Shortcut to my Library and played with it both within the Shortcuts App and via the voice command: "Hey Siri: Guitar Chord Finder". Both worked as expected.
I was also able to easily modify the shortcut to support ukulele as requested by my user. I just added ?instrument=Ukulele to the url field and replaced the image width rule with one that matches images with width greater than 100px.
To check if users are actually using this feature, I scanned my log files. Sure enough, the following user agent string started appearing thousands of times a day in jguitar.com's web server logs on 9/17/2018:
Shortcuts/700 CFNetwork/974.2.1 Darwin/18.0.0
super cool man!
ReplyDeleteUh - so let me get this straight.... they are using your results without giving you credit - nor are they letting you get ad revenue? That doesn't seem great to me. Unless I'm misunderstanding...

DeleteI'm with Tony on this...Hot Linking is a bandwidth tapeworm, are they reimbursing you for additional bandwidth usage?

DeleteAt a minimum you should add a JGuitar.com watermark on the bottom of each image. Better would be getting a bit of coin from Apple to cover the costs. This includes your time.
ReplyDeleteThe evil side of me thinks you should randomly replace the images with cats or porn.

DeleteI'm upset, you didnt get payed.
ReplyDeleteThis is one of the most rich companies yet you got nothing.
Maybe you can sue apple for this, think you have a good chance.
Your in a much better position than Microsoft or Samsung with this.

Delete"Maybe you can sue apple for this, think you have a good chance."
ReplyDeleteThat's the spirit! Don't be happy they use your service, SUE THEM!
Tell them where they can mail your free iPhone for testing.
ReplyDeleteThis shortcut was actually already in the Workflow app, so this the only decision Apple would have made was not to remove it - pretty bad though as obviously just 'steals' your work without any info to the user where the data is coming from.
ReplyDeleteThat implies that Apple now needs to manually inspect every single Workflow as well as every update each time one is tweaked or adjusted, which would be insanely impossible.
DeleteYou can always use mod rewrite to detect the user agent, then append your web site name at the bottom of the image via image magick and the like. I used to do that when I ran an image board and people direct linked to images posted on the board (as well as reduce the resolution slightly to help with bandwidth costs and cache the result).
ReplyDeleteI couldn't get the modified shortcut to work. It would be awesome if you could share it somewhere. :)
