Paket pack: need a way to specify current nuget version as dependency

[eiriktsarpalis]

I'm interested in integrating the paket pack functionality in my projects, so I've started playing around with it in FsPickler. In FsPickler there are two projects, FsPickler and FsPickler.Json. FsPickler has no nuget dependencies and FsPickler.Json depends on 1) Json.Net and 2) FsPickler of precisely the same version number.

I can rely on the Json.Net dependency being added automatically by paket pack, however I can't find a way to specify the latter dependency correctly. Is there any way I can achieve this through the paket.template syntax or FAKE?

Mhm good question. @mavnn do you have a suggestion how we could implement such a feature?

[forki]

@eiriktsarpalis how would you like to configure this feature. I think I can add it easily, but we need to define where and how.

[eiriktsarpalis]

I could think if two possible ways: either use a macro in the template
syntax for the current version or have FAKE pass additional dependencies to
the pack configuration record.

I think it should be done in the template.

I tend to agree, it would make package definitions more self contained.

do you already started the conversion? I'd love to use it as a sample to implement this.

[eiriktsarpalis]

Yeah, I started an effort in this branch, though I never completed it.

I'm getting the following error while trying to pack that FsPickler branch with 1.9.0:

thx. I found this bug and fixed it in 1.9.1.
it now works on my machine, but only after I renamed your "Paket.template" files to "paket.template" (all lowercase)

[eiriktsarpalis]

Thanks, seems to be working now.
