Where command line arguments are supported they can be read in via the get_command_argument intrinsic (introduced in the Fortran 2003 standard). The command_argument_count intrinsic provides a way to know the number of arguments provided at the command line.
All command-line arguments are read in ...
Slightly counterintuitively (but also the only sane way to make it work), this:
val dyn: Dynamic = ???
dyn.x(y) = z
is equivalent to:
dyn.selectDynamic("x").update(y, z)
while
dyn.x(y)
is still
dyn.applyDynamic("x")(y)
It is important to be aware of this, or else...
Result<T, E> is an enum type which has two variants: Ok(T) indicating successful execution with meaningful result of type T, and Err(E) indicating occurrence of an unexpected error during execution, described by a value of type E.
enum DateError {
InvalidDay,
InvalidMonth,

Using a CASE statement, conditionally display an expression in the column based on values found in another column, a.k.a. “my kingdom for an OR”. In the example, the result is obtained when the status of the transaction is Pending Fulfillment or Partially Fulfilled:

In a string formula field, consider that some values might contain substrings which look to the browser like HTML. Unless this is intentional, it is important to protect the values from corruption. This is useful to avoid injection attacks: it prevents someone from entering HTML into a comment field...
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 &nbsp; (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}`
},

If you haven't already lets simply start this file of with:

The first thing you should do, is define the $url_segment that will be used to access the interface, and the title ($menu_title) that will appear in the side navigation m...
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...

You may want to do this if the remote repository is migrated. The command for changing the remote url is:
git remote set-url
It takes 2 arguments: an existing remote name (origin, upstream) and the url.
Check your current remote url:
git remote -v

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()
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 ...
Inheritance among models can be done in two ways:
a common abstract class (see the "Model mixins" example)
a common model with multiple tables
The multi tables inheritance will create one table for the common fields and one per child model example:
from django.db import models

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");

Not everything in a bindings library will have the same name in C# as it does in Java.
In C#, interface names start with "I", but Java has no such convention. When you import a Java library, an interface named SomeInterface will become ISomeInterface.
Similarly, Java doesn't have propert...
