Given myapp and a dependency, specified by dub.json's:

myapp: dub.json
{
  ...
  "dependencies": {
    "dependency_a": ">=0.6.0"		
  }
  ...
}

dependency_a: dub.json
{
  ...
  "configurations": [
  {
    "name": "config_a",
    "targetType": "library",
    ...
  },
  {
    "name": "config_b",
    "targetType": "executable",
    ...
  },
  ...
}

How do I specify (in myapp: dub.json) that I want the "config_a" configuration of dependency_a?

I just want to verify, you are using configurations only to determine if its being built a certain way?
And not lets say as a subpackage?

Ignoring that, there is something called subConfigurations section.

Example from: http://code.dlang.org/package-format
{
	...
	"name": "somepackage"
	"configurations": [
		{
			"name": "metro-app",
			"targetType": "executable",
			"platforms": ["windows"],
			"versions": ["MetroApp"],
			"libs": ["d3d11"]
		},
		{
			"name": "desktop-app",
			"targetType": "executable",
			"platforms": ["windows"],
			"versions": ["DesktopApp"],
			"libs": ["d3d9"]
		},
		{
			"name": "glut-app",
			"targetType": "executable",
			"versions": ["GlutApp"]
		}
	]
}

{
	...
	"dependencies": {
		"somepackage": ">=1.0.0"
	},
	"subConfigurations": {
		"somepackage": "glut-app"
	}
}

I forgot to mention dub should automatically choose the first configuration available if you do not specify it.
In this case that's the library one. Or atleast it should do that.

Some dependency (that I don't control) might define for example two configurations, a sourceLibrary type and a library type (my own app does not define it's own configurations). I'm just wondering if there is a way to tell dub i'm only interested in using that dependency as a sourceLibrary for example.

Ahh I guess this is it, thanks for that!
