To change the URL of the repository you want your remote to point to, you can use the set-url option, like so:
git remote set-url <remote_name> <remote_repository_url>
Example:
git remote set-url heroku https://git.heroku.com/fictional-remote-repository.git
Express is based on Connect, which is what provides the middleware functionality of Express. To understand what connect is, you can see that it provides the basic app structure that you use when you use express
const connect = require('connect')
const app = connect()
app.listen(3000)
This wi...
If we would like to limit the access to our app, we could write a middleware for that too! This example only grants you access on thrusdays, but a real world example could, for example, be user authentication. A good place to put this would be after the logging middleware but before any content is s...
Use quasiquotes to create a Tree in a macro.
object macro {
def addCreationDate(): java.util.Date = macro impl.addCreationDate
}
object impl {
def addCreationDate(c: Context)(): c.Expr[java.util.Date] = {
import c.universe._
val date = q"new java.util.Date()" // this...
std::optional<float> divide(float a, float b) {
if (b!=0.f) return a/b;
return {};
}
Here we return either the fraction a/b, but if it is not defined (would be infinity) we instead return the empty optional.
A more complex case:
template<class Range, class Pred>
auto find_if...
void print_name( std::ostream& os, std::optional<std::string> const& name ) {
std::cout "Name is: " << name.value_or("<name missing>") << '\n';
}
value_or either returns the value stored in the optional, or the argument if there is nothing s...
If you have loaded a file into GHCi (e.g. using :l filename.hs) and you have changed the file in an editor outside of GHCi you must reload the file with :r or :reload in order to make use of the changes, hence you don't need to type again the filename.
ghci> :r
OK, modules loaded: Main.

Launch mode defines the behaviour of new or existing activity in the task.
There are possible launch modes:
standard
singleTop
singleTask
singleInstance
It should be defined in android manifest in <activity/> element as android:launchMode attribute.

A string can be written to a file with an instance of the File class.
file = File.new('tmp.txt', 'w')
file.write("NaNaNaNa\n")
file.write('Batman!\n')
file.close
The File class also offers a shorthand for the new and close operations with the open method.
File.open('tmp.txt', 'w') ...
You can call an instance method using the . special form:
(.trim " hello ")
;;=> "hello"
You can call instance methods with arguments like this:
(.substring "hello" 0 2)
;;=> "he"
You can create instance of objects in one of two ways:
(java.awt.Point. 0 1)
;;=> => #object[java.awt.Point 0x3776d535 "java.awt.Point[x=0,y=1]"]
Or
(new java.awt.Point 0 1)
;;=> => #object[java.awt.Point 0x3776d535 "java.awt.Point[x=0,y=1]"]
You can call static methods like this:
(System/currentTimeMillis)
;;=> 1469493415265
Or pass in arguments, like this:
(System/setProperty "foo" "42")
;;=> nil
(System/getProperty "foo")
;;=> "42"
You can call a Clojure function from Java code by looking up the function and invoking it:
IFn times = Clojure.var("clojure.core", "*");
times.invoke(2, 2);
This looks up the * function from the clojure.core namespace and invokes it with the arguments 2 & 2.
The macro() function allows you to add new functionality to Illuminate\Support\Collection objects
Usage:
Collection::macro("macro_name", function ($parameters) {
// Your macro
});
For example:
Collection::macro('uppercase', function () {
return $this->map(function ($i...
Also known as triple equals.
This operator does not test equality, but rather tests if the right operand has an IS A relationship with the left operand. As such, the popular name case equality operator is misleading.
This SO answer describes it thus: the best way to describe a === b is "if I ...

There are several ways to compile your app. You can use the simulator/emulator, deploy it to your device or create store apk's/ipa's. There is also a live test tool (TiShadow) which saves you a lot of time waiting for the compiler.
