Fix Missing hutDirectory on OSX

Extension

In the OSX version of SC up to release 3.7.0, the directory containing semantic information on HID devices is missing. This glitch makes HID harder to use; semantic HIDFunc and HIDdef methods will not work properly:HIDdef.usage(\x, { }, \X); // X-axis of mouse

So it is worth repairing until newer SC releases fix this.// * check if hutDirectory is missing: ~hutDirMissing = HIDUsage.hutDirectory.pathMatch.postcs.isEmpty; // if ~hutDirMissing is true, goto the sensestage/hidapi project page "https://github.com/sensestage/hidapi".openOS; // * download hidapi master from there // * then open the directory where the missing dir should go: HIDUsage.hutDirectory.dirname.dirname.openOS; // * make a new folder there called "HID_Support", // * and copy the folder /hidapi-master/hut/ there. // * now check that hutDirectory is in place and you see it here: HIDUsage.hutDirectory.pathMatch.cs; // you should see -> [ "/Applications/SuperCollider3.7/SuperCollider3.7.app/Contents/Resources/SCClassLibrary/Common/Control/HID_support/hut/" ] // you should get other lookup values than 'undefined' now: HIDUsage.getUsageDescription(9, 6).cs; // -> [ 'Button', 'b6' ]
