Environment variable not work with local repo

[aleksandr-shevchenko]

Composer ver.2.5.5, Win10

Environment variables work in Windows when I use local package with "type": "path", but not work with local repo with "type": "vcs".

My composer.json:

    "repositories": [
    {
            "type": "vcs",
            "url": "d:/Rabota/PHP/_packages_/alex"
        }
    ],
    "require": {
        "alex/alex": "dev-master"
    }

work fine.

But (when MY_PHP_PATH=d:\Rabota\PHP)

    "repositories": [
    {
            "type": "vcs",
            "url": "$MY_PHP_PATH/_packages_/alex"
        }
    ],
    "require": {
        "alex/alex": "dev-master"
    }

not work.

Output of composer diagnose:

In VcsRepository.php line 191:

  No driver found to handle VCS repository $MY_PHP_PATH/_packages_/alex

I would say that they work in path only by luck (and they might not work cross-platform)

[aleksandr-shevchenko]

from documentation about path

Leading tildes are expanded to the current user's home folder, and environment variables are parsed in both Windows and Linux/Mac notations.

OK, then it is not by luck.

However, for VCS repositories, I would say that this not expanding them is done on purpose as the main use case for VCS repositories is to use remove URLs, not local paths.

[Seldaek]

Right, but I think it would be pretty harmless to support them as well in VCS repo. Given we only support them at the beginning of the URL it would anyway not be supported for all https:// etc URLs, which makes it unlikely to backfire.
