This uses the Dropbox Python SDK to create a shared link for a folder: import dropbox dbx = dropbox.Dropbox("<ACCESS_TOKEN>") shared_link_metadata = dbx.sharing_create_shared_link_with_settings("/Testing") print shared_link_metadata.url <ACCESS_TOKEN> should be...

Dropbox.authorizedClient!.sharing.createSharedLink(path: "/test.txt").response({ response, error in if let link = response { print(link.url) } else { print(error!) } })

Git provides multiple commands for listing branches. All commands use the function of git branch, which will provide a list of a certain branches, depending on which options are put on the command line. Git will if possible, indicate the currently selected branch with a star next to it. GoalCommand...

JavaScript has two primary ways to represent binary data in the browser. ArrayBuffers/TypedArrays contain mutable (though still fixed-length) binary data which you can directly manipulate. Blobs contain immutable binary data which can only be accessed through the asynchronous File interface. Conver...

DataViews provide methods to read and write individual values from an ArrayBuffer, instead of viewing the entire thing as an array of a single type. Here we set two bytes individually then interpret them together as a 16-bit unsigned integer, first big-endian then little-endian. var buffer = new Ar...

var data = 'iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACN' + 'byblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHx' + 'gljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='; var characters = atob(data); var array = new Uint8Array(characters.length); for (var i = 0; i < characters.length; i++) { array[i] ...

5.1 When you take a reference to a method (a property which is a function) in JavaScript, it usually doesn't remember the object it was originally attached to. If the method needs to refer to that object as this it won't be able to, and calling it will probably cause a crash. You can use the .bind...

Template literals are a special type of string literal that can be used instead of the standard '...' or "...". They are declared by quoting the string with backticks instead of the standard single or double quotes: `...`. Template literals can contain line breaks and arbitrary expression...

Inheritance in Python is based on similar ideas used in other object oriented languages like Java, C++ etc. A new class can be derived from an existing class as follows. class BaseClass(object): pass class DerivedClass(BaseClass): pass The BaseClass is the already existing (parent)...

Instance variables are unique for each instance, while class variables are shared by all instances. class C: x = 2 # class variable def __init__(self, y): self.y = y # instance variable C.x # 2 C.y # AttributeError: type object 'C' has no attribute 'y' c1 = C(3) c1....

The idea of bound and unbound methods was removed in Python 3. In Python 3 when you declare a method within a class, you are using a def keyword, thus creating a function object. This is a regular function, and the surrounding class works as its namespace. In the following example we declare method ...

#! /bin/bash for i in {1..10}; do # {1..10} expands to "1 2 3 4 5 6 7 8 9 10" echo $i done This outputs the following: 1 2 3 4 5 6 7 8 8 10

In the same module Inside a module named "MyModule", Xcode generates a header named MyModule-Swift.h which exposes public Swift classes to Objective-C. Import this header in order to use the Swift classes: // MySwiftClass.swift in MyApp import Foundation // The class must be `public`...

If MyFramework contains Objective-C classes in its public headers (and the umbrella header), then import MyFramework is all that's necessary to use them from Swift. Bridging headers A bridging header makes additional Objective-C and C declarations visible to Swift code. When adding project files, ...

The -import-objc-header flag specifies a header for swiftc to import: // defs.h struct Color { int red, green, blue; }; #define MAX_VALUE 255 // demo.swift extension Color: CustomStringConvertible { // extension on a C struct public var description: String { return &q...

A rebase switches the meaning of "ours" and "theirs": git checkout topic git rebase master # rebase topic branch on top of master branch Whatever HEAD's pointing to is "ours" The first thing a rebase does is resetting the HEAD to master; before cherry-picking...

import java.awt.FlowLayout; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.SwingUtilities; public class CustomFrame extends JFrame { private static CustomFrame statFrame; public CustomFrame(String labelText) { setSize(500, 500); ...

git rev-list --oneline master ^origin/master Git rev-list will list commits in one branch that are not in another branch. It is a great tool when you're trying to figure out if code has been merged into a branch or not. Using the --oneline option will display the title of each commit. The ^ ...

Functions can be declared without parameters or a return value. The only required information is a name (hello in this case). func hello() { print("Hello World") } Call a function with no parameters by writing its name followed by an empty pair of parenthesis. hello() //output...
