Hi Sönke,

Sorry for the repost, I incorrectly replied to myself in the last post...

There's a little problem when I tried ddb:

I want to try it with a simple project, so I 

dub init hello

and then modified package.json to add "ddb" : "~master".

Then when I ran dub

it automatilly finds dependency vibe-d~master and then echos the error:

Compiling...
source/app.d(3): Error: only one main allowed

So using ddb changes the project to a vibe.d project, but I only want to do a simple void main() experiment.

I checked the source code of ddb in https://github.com/etcimon/ddb/blob/master/package.json 

{
        "name": "ddb",
        "description": "Asynchronous Postgresql Binding",
        "license": "Boost License 1.0",
        "copyright": "Copyright © 2013 Piotr Szturmaj",
        "homepage": "https://github.com/pszturmaj/",
        "authors": ["Piotr Szturmaj"],
        "targetType": "sourceLibrary",
        "dependencies": {
                "vibe-d": {"version":"~master"}
        },
        "versions": ["Have_vibe_d"]
}

It seems that one should be able to NOT use vibe.d (because to use vibe.d one should use version Have_vibe_d, right?).

Is there a config value in package.json to disable the dependency for vibe.d in dub, and then tells the ddb lib that we are not using version Have_vibe_d?

Hi,

Is there currently a postgre binding/lib that works with vibe.d? From the docs it seems that an external I/O libaray needs to support an async connection in order to be workable with vibe.d.
In the case of a sql client, we need to change its socket to an async socket right? For the case of mysql, people got an native implementation in D and modified its source code to make this happen.
But what about postgre? What do we need to do to make it happen? For the case of a biding, do we need to modify its C code?

Just in time :)

I think it was written from scratch based on the public protocol
specification.
