Hello,
Following the RFC process, I'm sending this to propose a PHP change. More
precisely a new zend language token.
This is somehow linked to the recently accepted RFC called "new
MyClass()->method() without parentheses", the goal is to introduce a
shorthand for the "new" keyword.
*Motivations :*
The new keyword sometime has a bad DX, for example when chaining Class
instantiation like this :
$foobar = new Foo( new Bar(), new Etc());
We can quickly have very long class object construction in some case.
In lot of Framework, to improve DX, static function construct are often
used to avoid the new keyword, some create additional object builders, etc.
As a first try, I start updated code to completely make the new keyword
optional, like in Dart language for example, but it require very big
change, with lot of impact (collision with function).
So here is *my proposal : *
Add a "new" shorthand, using the tilde character : "~"
I made a POC, and it works well, declaring a new language token T_SHORT_NEW
that simply reuse ZEND_AST_NEW under the hood.
Here are some example of what it may look like for userland, through some
tests I wrote :
--TEST--
New keyword shorthand
--FILE--
<?php
class A {
public function b() {
echo "I'm B";
}
}
~A()->b();
?>
--EXPECT--
I'm B
Other with nested :
--TEST--
New keyword shorthand encapsulation
--FILE--
<?php
class Foo {
public function __construct(
public string $name
) {}
}
class Bar {
public function __construct(
public Foo $foo
) {}
}
$bar = ~Bar(~Foo("I'm foo in bar"));
echo $bar->foo->name;
?>
--EXPECT--
I'm foo in bar
As a last word, just wanted to add it will work on nested Attribute too, so
for example this nested Attribute used in Doctrine :
#[AttributeOverrides([
new AttributeOverride(
name: "id",
column: new Column(name: "guest_id", type: "integer", length: 140)
),
new AttributeOverride(
name: "name",
column: new Column(name: "guest_name", nullable: false, unique:
true, length: 240)
)]
)]
Will also work like this :
#[AttributeOverrides([
~AttributeOverride(
name: "id",
column: new Column(name: "guest_id", type: "integer", length: 140)
),
~AttributeOverride(
name: "name",
column: new Column(name: "guest_name", nullable: false, unique:
true, length: 240)
)]
)]
About implementation, it should'n have any impact on SAPI or extension, the
new keyword will still exist, it's just a new shorthand.
I think you get the point, is it something that some of you would be
interested in? I would be happy to make a proper RFC proposal.
