Autoloading issue: PSR-0 vs PSR-4

[live627]

Difference between psr-0 and psr-4

PSR-4 is something like 'relative path', PSR-0, 'absolute path'.

psr-0

Looking at vendor/composer/autoload_namespaces.php file you can see the namespaces and the directories that they are mapped to.

composer.json

"autoload": {
        "psr-0": {
            "Liquid\\": "src/"
        }
}

psr-4

Looking at vendor/composer/autoload_psr4.php file you can see the namespaces and the directories that they are mapped to.

composer.json

"autoload": {
    "psr-4": {
        "Liquid\\": "src/"
    }
}   

• Looking for Liquid\Template in src/Template.php

composer.json

"autoload": {
    "psr-4": {
        "Liquid\\": "src/Liquid/"
    }
}    

• Looking for Liquid\Template in src/Liquid/Template.php

How to fix

Either

• Move both sources and tests up one level
• Change autoloader to specify psr-0

Looking for Liquid\Template in src/Liquid/Template.php

Isn't this is what we have in actuality?

So, there is no bug, really, but an issue with not following the spec exactly.
