-/**
|
|
|
- * This module adds string interpolation support to Shifty.
|
|
|
- *
|
|
|
- * The Token extension allows Shifty to tween numbers inside of strings. Among
|
|
|
- * other things, this allows you to animate CSS properties. For example, you
|
|
|
- * can do this:
|
|
|
- *
|
|
|
- * var tweenable = new Tweenable();
|
|
|
- * tweenable.tween({
|
|
|
- * from: { transform: 'translateX(45px)' },
|
|
|
- * to: { transform: 'translateX(90xp)' }
|
|
|
- * });
|
|
|
- *
|
|
|
- * `translateX(45)` will be tweened to `translateX(90)`. To demonstrate:
|
|
|
- *
|
|
|
- * var tweenable = new Tweenable();
|
|
|
- * tweenable.tween({
|
|
|
- * from: { transform: 'translateX(45px)' },
|
|
|
- * to: { transform: 'translateX(90px)' },
|
|
|
- * step: function (state) {
|
|
|
- * console.log(state.transform);
|
|
|
- * }
|
|
|
- * });
|
|
|
- *
|
|
|
- * The above snippet will log something like this in the console:
|
|
|
- *
|
|
|
- * translateX(60.3px)
|
|
|
- * ...
|
|
|
- * translateX(76.05px)
|
|
|
- * ...
|
|
|
- * translateX(90px)
|
|
|
- *
|
|
|
- * Another use for this is animating colors:
|
|
|
- *
|
|
|
- * var tweenable = new Tweenable();
|
|
|
- * tweenable.tween({
|
|
|
- * from: { color: 'rgb(0,255,0)' },
|
|
|
- * to: { color: 'rgb(255,0,255)' },
|
|
|
- * step: function (state) {
|
|
|
- * console.log(state.color);
|
|
|
- * }
|
|
|
- * });
|
|
|
- *
|
|
|
- * The above snippet will log something like this:
|
|
|
- *
|
|
|
- * rgb(84,170,84)
|
|
|
- * ...
|
|
|
- * rgb(170,84,170)
|
|
|
- * ...
|
|
|
- * rgb(255,0,255)
|
|
|
- *
|
|
|
- * This extension also supports hexadecimal colors, in both long (`#ff00ff`)
|
|
|
- * and short (`#f0f`) forms. Be aware that hexadecimal input values will be
|
|
|
- * converted into the equivalent RGB output values. This is done to optimize
|
|
|
- * for performance.
|
|
|
- *
|
|
|
- * var tweenable = new Tweenable();
|
|
|
- * tweenable.tween({
|
|
|
- * from: { color: '#0f0' },
|
|
|
- * to: { color: '#f0f' },
|
|
|
- * step: function (state) {
|
|
|
- * console.log(state.color);
|
|
|
- * }
|
|
|
- * });
|
|
|
- *
|
|
|
- * This snippet will generate the same output as the one before it because
|
|
|
- * equivalent values were supplied (just in hexadecimal form rather than RGB):
|
|
|
- *
|
|
|
- * rgb(84,170,84)
|
|
|
- * ...
|
|
|
- * rgb(170,84,170)
|
|
|
- * ...
|
|
|
- * rgb(255,0,255)
|
|
|
- *
|
|
|
- * ## Easing support
|
|
|
- *
|
|
|
- * Easing works somewhat differently in the Token extension. This is because
|
|
|
- * some CSS properties have multiple values in them, and you might need to
|
|
|
- * tween each value along its own easing curve. A basic example:
|
|
|
- *
|
|
|
- * var tweenable = new Tweenable();
|
|
|
- * tweenable.tween({
|
|
|
- * from: { transform: 'translateX(0px) translateY(0px)' },
|
|
|
- * to: { transform: 'translateX(100px) translateY(100px)' },
|
|
|
- * easing: { transform: 'easeInQuad' },
|
|
|
- * step: function (state) {
|
|
|
- * console.log(state.transform);
|
|
|
- * }
|
|
|
- * });
|
|
|
- *
|
|
|
- * The above snippet will create values like this:
|
|
|
- *
|
|
|
- * translateX(11.56px) translateY(11.56px)
|
|
|
- * ...
|
|
|
- * translateX(46.24px) translateY(46.24px)
|
|
|
- * ...
|
|
|
- * translateX(100px) translateY(100px)
|
|
|
- *
|
|
|
- * In this case, the values for `translateX` and `translateY` are always the
|
|
|
- * same for each step of the tween, because they have the same start and end
|
|
|
- * points and both use the same easing curve. We can also tween `translateX`
|
|
|
- * and `translateY` along independent curves:
|
|
|
- *
|
|
|
- * var tweenable = new Tweenable();
|
|
|
- * tweenable.tween({
|
|
|
- * from: { transform: 'translateX(0px) translateY(0px)' },
|
|
|
- * to: { transform: 'translateX(100px) translateY(100px)' },
|
|
|
- * easing: { transform: 'easeInQuad bounce' },
|
|
|
- * step: function (state) {
|
|
|
- * console.log(state.transform);
|
|
|
- * }
|
|
|
- * });
|
|
|
- *
|
|
|
- * The above snippet will create values like this:
|
|
|
- *
|
|
|
- * translateX(10.89px) translateY(82.35px)
|
|
|
- * ...
|
|
|
- * translateX(44.89px) translateY(86.73px)
|
|
|
- * ...
|
|
|
- * translateX(100px) translateY(100px)
|
|
|
- *
|
|
|
- * `translateX` and `translateY` are not in sync anymore, because `easeInQuad`
|
|
|
- * was specified for `translateX` and `bounce` for `translateY`. Mixing and
|
|
|
- * matching easing curves can make for some interesting motion in your
|
|
|
- * animations.
|
|
|
- *
|
|
|
- * The order of the space-separated easing curves correspond the token values
|
|
|
- * they apply to. If there are more token values than easing curves listed,
|
|
|
- * the last easing curve listed is used.
