在composer中指定PSR-0命名空间的根目录

Question

I current have the following composer.json file:

{
    "require": {
        "slim/slim": "2.*"
    },
    "autoload": {
        "psr-0": { "App": "app/" }
    }
}

I'm trying to instantiate a class in the app folder, but the autoloader is looking for:

/var/www/framework/app//App/App.php

Obviously the second parameter is the folder containing the namespace rather than the root of the namespace. How can I make it load:

/var/www/framework/app/App.php

Thanks in advance!

Answer 1

The easiest solution is to rename the folder from app to App and set

"psr-0": { "App": "." }

I guess else you need a custom autoloader. However, I recommend to follow some proven use-cases:

src/App/App.php

with

"psr-0": { "App": "src" }

Looks curious, but I must say, that I would never call a namespace or class (or even both) just App ;) It doesn't say anything and with aliasing (use MyApplication as App) there is no reason anymore to write as short identifiers as possible.
