The option to add classes to compile using patterns was introduced in Symfony 3.2.

The classes to compile can also be added using file path patterns::

// ...

179+
{
180+
// ...

188+
'**Bundle\\Controller\\',
189+
// ...
190+
));
191+
}
192+
193+
Patterns are transformed into the actual class namespaces using the classmap
194+
generated by Composer. Therefore, before using these patterns, you must generate
195+
the full classmap executing the ``dump-autoload`` command of Composer.

Dumping and Manipulating the AST of Expressions
6+
===============================================
7+
8+
Manipulating or inspecting the expressions created with the ExpressionLanguage
9+
component is difficult because they are plain strings. A better approach is to
10+
turn those expressions into an AST. In computer science, `AST`_ (*Abstract
11+
Syntax Tree*) is *"a tree representation of the structure of source code written
12+
in a programming language"*. In Symfony, a ExpressionLanguage AST is a set of
13+
nodes that contain PHP classes representing the given expression.
14+
15+
Dumping the AST
16+
---------------
17+
18+
Call the :method:`Symfony\\Component\\ExpressionLanguage\\ExpressionLanguage::getNodes`
19+
method after parsing any expression to get its AST::
20+
21+
use Symfony\Component\ExpressionLanguage\ExpressionLanguage;
22+
23+
$ast = (new ExpressionLanguage())
24+
->parse('1 + 2')
25+
->getNodes()
26+
;
27+
28+
// dump the AST nodes for inspection
29+
var_dump($ast);
30+
31+
// dump the AST nodes as a string representation
32+
$astAsString = $ast->dump();
33+
34+
Manipulating the AST
35+
--------------------
36+
37+
The nodes of the AST can also be dumped into a PHP array of nodes to allow
38+
manipulating them. Call the :method:`Symfony\\Component\\ExpressionLanguage\\ExpressionLanguage::toArray`
39+
method to turn the AST into an array::
40+
41+
// ...
42+
43+
$astAsArray = (new ExpressionLanguage())
44+
->parse('1 + 2')
45+
->getNodes()
