Road to basic Linux compatibility

[felix91gr]

I want to try and make a PR that lets you compile Sourcery and get basic, on-demand, templating working.

This idea has two goals:
a) Make Sourcery-based projects available for Linux
b) Make generation of the LinuxMain.swift file possible on Linux.

How should I start? @mxcl gave some hints at #306 but I don't really know how to make that more concrete.

[mxcl]

I just pushed what work I did to my fork.

[felix91gr]

Thank you!

What's left to do in order to get a working "baseline Sourcery"?

I got this output:

error: could not find target(s): Sourcery; use the 'path' property in the Swift 4 manifest to set a custom target path

---

Edit: fixed it, but now I get a different error. I added path: "Sourcery" to the target called mainTarget.

This is what I get now. It might not be fixable, sounds like it depends on ObjC:

@felix91gr it looks like you just need to change base to NSObject, and tweak couple of declarations to happen inside the definition and not extension, the error messages here are looking normal, those changes are just required with newer toolchain

it looks like you just need to change base to NSObject

I understood this on principle, but I looked up those classes and all of them directly or transitively inherit from NSObject. I must be missing something 🤔

Which toolchain should I use? I was using Swift 4.0 to compile these.

This is implemented with #1188
