gesture glossary ✌️

-

This is the home page for the gesture glossary. It has every word in the glossary to the right. Click a word to visit its page. This is the introduction.

+

This is the the gesture glossary. Click a word to the right to see the gestures related to it.

+

The aim is to see if a gesture glossary works and how it will work best. Also to see what kind of different interpretations there will be on gestures of our memory. To test the gesture glossary idea, and see what different meanings appear or already exist in the current vocabulary. Putting next to each other different agreements on linguistic and body units, testing what makes sense. Investigating and playing with communicational channel in between us, how a body language is documented, how it expands, how it is capable of creating or enhancing identities. To be an xpub means to speak/perform the xpub language?

The + primary way of interacting with a promise is through its `then` method, which + registers callbacks to receive either a promise's eventual value or the reason + why the promise cannot be fulfilled. + + Terminology + ----------- + + - `promise` is an object or function with a `then` method whose behavior conforms to this specification. + - `thenable` is an object or function that defines a `then` method. + - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). + - `exception` is a value that is thrown using the throw statement. + - `reason` is a value that indicates why a promise was rejected. + - `settled` the final resting state of a promise, fulfilled or rejected. + + A promise can be in one of three states: pending, fulfilled, or rejected. + + Promises that are fulfilled have a fulfillment value and are in the fulfilled + state. Promises that are rejected have a rejection reason and are in the + rejected state. A fulfillment value is never a thenable. + + Promises can also be said to *resolve* a value. If this value is also a + promise, then the original promise's settled state will match the value's + settled state. So a promise that *resolves* a promise that rejects will + itself reject, and a promise that *resolves* a promise that fulfills will + itself fulfill. + + + Basic Usage: + ------------ + + ```js + let promise = new Promise(function(resolve, reject) { + // on success + resolve(value); + + // on failure + reject(reason); + }); + + promise.then(function(value) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Advanced Usage: + --------------- + + Promises shine when abstracting away asynchronous interactions such as + `XMLHttpRequest`s. + + ```js + function getJSON(url) { + return new Promise(function(resolve, reject){ + let xhr = new XMLHttpRequest(); + + xhr.open('GET', url); + xhr.onreadystatechange = handler; + xhr.responseType = 'json'; + xhr.setRequestHeader('Accept', 'application/json'); + xhr.send(); + + function handler() { + if (this.readyState === this.DONE) { + if (this.status === 200) { + resolve(this.response); + } else { + reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); + } + } + }; + }); + } + + getJSON('/posts.json').then(function(json) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Unlike callbacks, promises are great composable primitives. + + ```js + Promise.all([ + getJSON('/posts'), + getJSON('/comments') + ]).then(function(values){ + values[0] // => postsJSON + values[1] // => commentsJSON + + return values; + }); + ``` + + @class Promise + @param {Function} resolver + Useful for tooling. + @constructor +*/ + + var Promise$1 = (function() { + function Promise(resolver) { + this[PROMISE_ID] = nextId(); + this._result = this._state = undefined; + this._subscribers = []; + + if (noop !== resolver) { + typeof resolver !== 'function' && needsResolver(); + this instanceof Promise + ? initializePromise(this, resolver) + : needsNew(); + } + } + + /** + The primary way of interacting with a promise is through its `then` method, + which registers callbacks to receive either a promise's eventual value or the + reason why the promise cannot be fulfilled. + ```js + findUser().then(function(user){ + // user is available + }, function(reason){ + // user is unavailable, and you are given the reason why + }); + ``` + Chaining + -------- + The return value of `then` is itself a promise. This second, 'downstream' + promise is resolved with the return value of the first promise's fulfillment + or rejection handler, or rejected if the handler throws an exception. + ```js + findUser().then(function (user) { + return user.name; + }, function (reason) { + return 'default name'; + }).then(function (userName) { + // If `findUser` fulfilled, `userName` will be the user's name, otherwise it + // will be `'default name'` + }); + findUser().then(function (user) { + throw new Error('Found user, but still unhappy'); + }, function (reason) { + throw new Error('`findUser` rejected and we're unhappy'); + }).then(function (value) { + // never reached + }, function (reason) { + // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. + // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. + }); + ``` + If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. + ```js + findUser().then(function (user) { + throw new PedagogicalException('Upstream error'); + }).then(function (value) { + // never reached + }).then(function (value) { + // never reached + }, function (reason) { + // The `PedgagocialException` is propagated all the way down to here + }); + ``` + Assimilation + ------------ + Sometimes the value you want to propagate to a downstream promise can only be + retrieved asynchronously. This can be achieved by returning a promise in the + fulfillment or rejection handler. The downstream promise will then be pending + until the returned promise is settled. This is called *assimilation*. + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // The user's comments are now available + }); + ``` + If the assimliated promise rejects, then the downstream promise will also reject. + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // If `findCommentsByAuthor` fulfills, we'll have the value here + }, function (reason) { + // If `findCommentsByAuthor` rejects, we'll have the reason here + }); + ``` + Simple Example + -------------- + Synchronous Example + ```javascript + let result; + try { + result = findResult(); + // success + } catch(reason) { + // failure + } + ``` + Errback Example + ```js + findResult(function(result, err){ + if (err) { + // failure + } else { + // success + } + }); + ``` + Promise Example; + ```javascript + findResult().then(function(result){ + // success + }, function(reason){ + // failure + }); + ``` + Advanced Example + -------------- + Synchronous Example + ```javascript + let author, books; + try { + author = findAuthor(); + books = findBooksByAuthor(author); + // success + } catch(reason) { + // failure + } + ``` + Errback Example + ```js + function foundBooks(books) { + } + function failure(reason) { + } + findAuthor(function(author, err){ + if (err) { + failure(err); + // failure + } else { + try { + findBoooksByAuthor(author, function(books, err) { + if (err) { + failure(err); + } else { + try { + foundBooks(books); + } catch(reason) { + failure(reason); + } + } + }); + } catch(error) { + failure(err); + } + // success + } + }); + ``` + Promise Example; + ```javascript + findAuthor(). + then(findBooksByAuthor). + then(function(books){ + // found books + }).catch(function(reason){ + // something went wrong + }); + ``` + @method then + @param {Function} onFulfilled + @param {Function} onRejected + Useful for tooling. + @return {Promise} + */ + + /** + `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same + as the catch block of a try/catch statement. + ```js + function findAuthor(){ + throw new Error('couldn't find that author'); + } + // synchronous + try { + findAuthor(); + } catch(reason) { + // something went wrong + } + // async with promises + findAuthor().catch(function(reason){ + // something went wrong + }); + ``` + @method catch + @param {Function} onRejection + Useful for tooling. + @return {Promise} + */ + + Promise.prototype.catch = function _catch(onRejection) { + return this.then(null, onRejection); + }; + + /** + `finally` will be invoked regardless of the promise's fate just as native + try/catch/finally behaves + + Synchronous example: + + ```js + findAuthor() { + if (Math.random() > 0.5) { + throw new Error(); + } + return new Author(); + } + + try { + return findAuthor(); // succeed or fail + } catch(error) { + return findOtherAuther(); + } finally { + // always runs + // doesn't affect the return value + } + ``` + + Asynchronous example: + + ```js + findAuthor().catch(function(reason){ + return findOtherAuther(); + }).finally(function(){ + // author was either found, or not + }); + ``` + + @method finally + @param {Function} callback + @return {Promise} + */ + + Promise.prototype.finally = function _finally(callback) { + var promise = this; + var constructor = promise.constructor; + + if (isFunction(callback)) { + return promise.then( + function(value) { + return constructor.resolve(callback()).then(function() { + return value; + }); + }, + function(reason) { + return constructor.resolve(callback()).then(function() { + throw reason; + }); + } + ); + } + + return promise.then(callback, callback); + }; + + return Promise; + })(); + + Promise$1.prototype.then = then; + Promise$1.all = all; + Promise$1.race = race; + Promise$1.resolve = resolve$1; + Promise$1.reject = reject$1; + Promise$1._setScheduler = setScheduler; + Promise$1._setAsap = setAsap; + Promise$1._asap = asap; + + /*global self*/ + function polyfill() { + var local = void 0; + + if (typeof global !== 'undefined') { + local = global; + } else if (typeof self !== 'undefined') { + local = self; + } else { + try { + local = Function('return this')(); + } catch (e) { + throw new Error( + 'polyfill failed because global object is unavailable in this environment' + ); + } + } + + var P = local.Promise; + + if (P) { + var promiseToString = null; + try { + promiseToString = Object.prototype.toString.call(P.resolve()); + } catch (e) { + // silently ignored + } + + if (promiseToString === '[object Promise]' && !P.cast) { + return; + } + } + + local.Promise = Promise$1; + } + + // Strange compat.. + Promise$1.polyfill = polyfill; + Promise$1.Promise = Promise$1; + + return Promise$1; + }); + }.call( + this, + _dereq_('_process'), + typeof global !== 'undefined' + ?

All data is + // referenced by a code, which represents one or more values from the + // original input stream. All input bytes can be referenced as the same + // value as an output code. So if you didn't want any compression, you + // could more or less just output the original bytes as codes (there are + // some details to this, but it is the idea). In order to achieve + // compression, values greater then the input range (codes can be up to + // 12-bit while input only 8-bit) represent a sequence of previously seen + // inputs. The decompressor is able to build the same mapping while + // decoding, so there is always a shared common knowledge between the + // encoding and decoder, which is also important for "timing" aspects like + // how to handle variable bit width code encoding. + // + // One obvious but very important consequence of the table system is there + // is always a unique id (at most 12-bits) to map the runs. 'A' might be + // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship + // can be used for an effecient lookup strategy for the code mapping. We + // need to know if a run has been seen before, and be able to map that run + // to the output code. Since we start with known unique ids (input bytes), + // and then from those build more unique ids (table entries), we can + // continue this chain (almost like a linked list) to always have small + // integer values that represent the current byte chains in the encoder. + // This means instead of tracking the input bytes (AAAABCD) to know our + // current state, we can track the table entry for AAAABC (it is guaranteed + // to exist by the nature of the algorithm) and the next character D. + // Therefor the tuple of (table_entry, byte) is guaranteed to also be + // unique. This allows us to create a simple lookup key for mapping input + // sequences to codes (table indices) without having to store or search + // any of the code sequences. So if 'AAAA' has a table entry of 12, the + // tuple of ('AAAA', K) for any input byte K will be unique, and can be our + // key.

In instance mode, all p5 functions + * are bound up in a single variable instead of polluting your global namespace. + * + * Optionally, you can specify a default container for the canvas and any other elements + * to append to with a second argument. You can give the ID of an element in your html, + * or an html node itself. + * + * Note that creating instances like this also allows you to have more than one p5 sketch on + * a single web page, as they will each be wrapped up with their own set up variables. Of + * course, you could also use iframes to have multiple sketches in global mode. + * + * @method p5 + * @param {Object} sketch a function containing a p5.js sketch + * @param {String|Object} node ID or pointer to HTML DOM node to contain sketch in + * @example + *
+ * const s = p => { + * let x = 100; + * let y = 100; + * + * p.setup = function() { + * p.createCanvas(700, 410); + * }; + * + * p.draw = function() { + * p.background(0); + * p.fill(255); + * p.rect(x, y, 50, 50); + * }; + * }; + * + * new p5(s); // invoke p5 + *

The main difference to the + * random() function is that Perlin noise is defined in an infinite + * n-dimensional space where each pair of coordinates corresponds to a + * fixed semi-random value (fixed only for the lifespan of the program; see + * the noiseSeed() function). p5.js can compute 1D, 2D and 3D noise, + * depending on the number of coordinates given. The resulting value will + * always be between 0.0 and 1.0. The noise value can be animated by moving + * through the noise space as demonstrated in the example above. The 2nd + * and 3rd dimension can also be interpreted as time.

The actual + * noise is structured similar to an audio signal, in respect to the + * function's use of frequencies. Similar to the concept of harmonics in + * physics, perlin noise is computed over several octaves which are added + * together for the final result.

Another way to adjust the + * character of the resulting sequence is the scale of the input + * coordinates. As the function works within an infinite space the value of + * the coordinates doesn't matter as such, only the distance between + * successive coordinates does (eg. when using noise() within a + * loop).
