Completion can be used to match words used in a document. When typing a word, Ctrlp or Ctrln will match previous or next similar words in the document.
This can even be combined with Ctrl-X mode to complete entire lines. For instance type something like:
This is an example sentence.

Nested for loops may be used to iterate over a number of unique iterables.
result = []
for a = iterable_a
for b = iterable_b
push!(result, expression)
end
end
Similarly, multiple iteration specifications may be supplied to an array comprehension.
[expression for a = iterabl...
Generator comprehensions follow a similar format to array comprehensions, but use parentheses () instead of square brackets [].
(expression for element = iterable)
Such an expression returns a Generator object.

BFS can be used to find the connected components of an undirected graph. We can also find if the given graph is connected or not. Our subsequent discussion assumes we are dealing with undirected graphs.The definition of a connected graph is:
A graph is connected if there is a path between every p...
A C library header can usually be included into a C++ program, since most declarations are valid in both C and C++. For example, consider the following foo.h:
typedef struct Foo {
int bar;
} Foo;
Foo make_foo(int);
The definition of make_foo is separately compiled and distributed with the...
To use jquery in your Angular 2.x components, declare a global variable on the top
If using $ for jQuery

The rule that typedef declarations have the same syntax as ordinary variable and function declarations can be used to read and write more complex declarations.

You can use @ComponentScan in order to configure more complex package scanning. There is also @ComponentScans that act as a container annotation that aggregates several @ComponentScan annotations.

You might need a v-model on a computed property. Normally, the v-model won't update the computed property value.
The template:
