In a saved search formula, the possible values of mainline are designed to be useful in an HTML context. When mainline is true, the value of {mainline} is the 1-character string * (asterisk). When mainline is false, the value of {mainline} is the 6-character string   (non-breaking space, HT...
JavaScript allows us to define getters and setters in the object literal syntax. Here's an example:
var date = {
year: '2017',
month: '02',
day: '27',
get date() {
// Get the date in YYYY-MM-DD format
return `${this.year}-${this.month}-${this.day}`
},
...
The expected structure of this template can be a bit convoluted but it all boils down to this:
There are 3 sections worth noting for this guide:
.north
.center
.south
It must be wrapped entirely within an element that has the data-pjax-fragment="Content" attribute. This is...

If we have a c++ project that uses a config.h configuration file with some custom paths or variables, we can generate it using CMake and a generic file config.h.in.
The config.h.in can be part of a git repository, while the generated file config.h will never be added, as it is generated from the cu...
Comparator cmp = [ compare:{ a, b -> a <=> b } ] as Comparator
def col = [ 'aa', 'aa', 'nn', '00' ]
SortedSet sorted = new TreeSet( cmp )
sorted.addAll col
assert '[00, aa, nn]' == sorted.toString()
Here is a very simple example of a function that "promises to proceed when a given time elapses". It does that by creating a new Deferred object, that is resolved later and returning the Deferred's promise:
function waitPromise(milliseconds){
// Create a new Deferred object using th...
Correlated (also known as Synchronized or Coordinated) Subqueries are nested queries that make references to the current row of their outer query:
SELECT EmployeeId
FROM Employee AS eOuter
WHERE Salary > (
SELECT AVG(Salary)
FROM Employee eInner
WHERE eInner.Dep...
my @letters = ( 'a' .. 'z' ); # English ascii-bet
print $letters[ rand @letters ] for 1 .. 5; # prints 5 letters at random
How it works
rand EXPR expects a scalar value, so @letters is evaluated in scalar context
An array in scalar context returns the number of elements it ...
The example reads the first line from a file. It uses an instance of BufferedReader to read data from the file. BufferedReader is a resource that must be closed after the program is finished with it:
static String readFirstLineFromFile(String path) throws IOException {
try (BufferedReader br = n...
You can use
Map<String, List<String>> myMap = new HashMap<>();
instead of
Map<String, List<String>> myMap = new HashMap<String, List<String>>();
However, you can't use
List<String> list = new ArrayList<>();
list.add("A");

If shift is called outside of a delimiting reset block, it can be used to create functions that themselves create continuations inside a reset block. It is important to note that shift's type is not just (((A => B) => C) => A), it is actually (((A => B) => C) => (A @cpsParam[B, C])...
In order to create a workspace, one should run the following in the terminal:
$ mkdir -p ~/workspace_name/src
$ cd ~/workspace_name/src
$ catkin_init_workspace
$ cd ~/workspace_name/
$ catkin_make
The previous commands creates a workspace named workspace_name. Once a workspace has been creat...
