How to build

System requirements to build Tinkle:

• macOS 11.0+
• Xcode 13+
• Command Line Tools for Xcode
• XcodeGen
• create-dmg

Steps

1. Get source code by executing a following command in Terminal.app.

   git clone --depth 1 https://github.com/pqrs-org/Tinkle.git
   cd Tinkle
   git submodule update --init --recursive --depth 1

2. Find your codesign identity if you have one.
   (Skip this step if you don't have your codesign identity.)

   security find-identity -p codesigning -v | grep 'Developer ID Application'

   The result is as follows.

   1) 8D660191481C98F5C56630847A6C39D95C166F22 "Developer ID Application: Fumihiko Takayama (G43BCU2T37)"
   

   Your codesign identity is 8D660191481C98F5C56630847A6C39D95C166F22 in the above case.

3. Set environment variable to use your codesign identity.
   (Skip this step if you don't have your codesign identity.)

   export PQRS_ORG_CODE_SIGN_IDENTITY=8D660191481C98F5C56630847A6C39D95C166F22

4. Build a package by executing a following command in Terminal.app.

   make package

   Tinkle-*.dmg will be generated.

   Note: If you don't have codesign identity, the dmg works only on your machine.

Playgrounds

Tinkle users Metal shader to make effects.
