custom-directory-installers
It's a fork of the official composer/installers but use the dynamic paths system of ideaconnect/composer-custom-directory in that way they are compatible each others.
How to use it
Declare your "composer/installers": "1.1.0"
as usually but add:
"repositories": [
{
"url": "https://github.com/WPBP/installers",
"type": "vcs"
},
]
In that way the packages that require in their composer.json don't annoying you but the dynamic paths system of ideaconnect/composer-custom-directory will works also with them.
Enjoy!
