[Code Assist] Code assist in included files ? [message #45883]

Hello. This is my first post in this group.

If I have the following class :

-[Module.php]--------------------------------
class Module {
function execute() {
include('action.php');
}
function foo() {
// Do something
}
}
---------------------------------------------

And the following file :

-[action.php]-----------------------------------
$this->foo();
---------------------------------------------

This is valid PHP code but code assist can not work
in the "action.php" file as the editor doesn't know
what "$this" can be.

Is there a way to make code assist work with a workaround ?

The simpliest trick I've found is the following :

-[Module.php]--------------------------------
/**
* @return Module
*/
function thisModule($module) {
return $module;
}

class Module {
function execute() {
include('action.php');
}
function foo() {
// Do something
}
}
---------------------------------------------

-[action.php]--------------------------------
$This=thisModule($this);
$This->foo();
---------------------------------------------

That works almost good (it gives code assist for all public method,
which is a good start)

Has anyone something lighter ? I look especially for a method that does
not imply the declaration of a specific function (like "thisModule()")
for each class.

Something like this should work.

-[action.php]--------------------------------
/*
* @var $this Module
*/

Thanks but it doesn't work here.

As far as I know, there are two obstacles to find a light workaround :
- you can't PHPDoc an isolated variable (like above)
- you can't cast an object to a given class in PHP
(so I can't write "$This = (Module) $this" )

Why don't you follow a more clear OOP way?

I'm not an advanced programmer but it seems that having one file per
view* and action is a very flexible and extendable way of programming.
It permits to add actions or views without editing and existing file
(so you can add custom functionnalities without modifying the core code).
Exponent CMS (exponentcms.org) is made that way and I was very happy to
release some new modules or even evolutions of existing modules with
only some files to *add*. If a user updates Exponent (the core code) he
doesn't need to re-install my features.
Considering that was a good idea (I am far for pretending it is
Exponent's idea - I am just telling my story) I reproduced it in my own
project.

The best OOP way would surely(?) to use nested classes in a partial class :

-[Module1/Module1.php]--
partial class Module1 {
}
------------------------

-[Module1/Action1.php]--
partial class Module1 {
class Action1 {
}
}
------------------------
But there is no partial class in php.
(nested classes could be replaced by simple methods if they are not
available)

Another way (that I think is not as good as the way above) would be to
use namespaces, but it doesn't exist in PHP either.

Without these solutions I would have to use classes like :
-[Module1/Action1.php]--
class Module1Action1 {
}
------------------------

But I will have dozens (hundreds ?) of classes with long and complicated
names which is not a good thing for extendability.

Moreover, all these solutions add almost useless "decoration" (I will
almost never use these classes as true OOP classes - so why would I
bother myself with declarations such as "class xxx{}" ?).

So I used "include" to execute actions and launch views :

-[Module1/Module1.php]----
class Module1 {
function execute() {
// This function dynamicaly chooses the "right" action.
// The following line is just a simple static example.
include('action1.php');
}
}
--------------------------

-[Module1/action1.php]----
// some actions to do...
--------------------------

This apparently works great.

I am not sure that I want to modify my architecture just to have
completion with "$this"...

note: I have tens of "modules" and each one has tens of actions and views.

* Whan I talk about "view", I talk about the part of the view which
assign variables to an HTML template and call its rendering. Maybe the
right name is "view controller" (?)

First of all this is not a PHPDoc at all, it's rather a type hinting
used to instruct a PDT of the type of variable.

I don't know if it works with $this (which is a special case), but I use
a single line version of it sometimes at the beginning of my templates
and it works.

/* @var $contracts contractsList */

I agree.
I just thought PDT could understand only valid PHPDoc statements.

Thanks.
The single line version works indeed.

It doesn't work with $this, but I can write $This=$this and instruct PDT
of the type of $This. It tried and it worked.
