Have you ever wanted to use D in a project where not everyone had D installed or maybe you wanted to fix the compiler to a specific version?

I typically use a simple Makefile in such cases and download my preferred DMD and LDC version. As others who I have shown this have found this useful, I thought it might be helpful to other people (even so it's pretty straight-forward).

The cool part about this is that you don't have to worry about anything. People can just type `make` and everything works magically.

It's essentially a poor man's version of virtualenv for use cases where people are too lazy to use the install script or auto-env/dir-env can't be used either.

I added a few other common "boilerplate" things (CI integration, CodeCov, Documentation build, linting, ...) to this template:

Happy bootstrapping!

Why not Docker?
---------------

Docker is typically used to allow a consistent work environment, but in my use cases Docker isn't available.
If you want to use Docker, check out the [D docker images](https://hub.docker.com/r/dlanguage/dmd/).

Additional bonus
----------------

Want to use D in a Web IDE?
Use [Cloud9](https://aws.amazon.com/cloud9), clone this repo and run `make` - it will work out of the box.

You're truly becoming the bearer of good news...

clojure's lein support starter templates. it'd be great if dub did such a thing too.

thanks for the effort.

Yep it would be nice and it's planned to support `-t` for dub init:

See https://github.com/dlang/dub/pull/1326#issuecomment-357233196

As always it happens faster if someone makes a PR for it ;-)

What does "|" do in a makefile?

The target depends on `bin` but don't rebuild the target if `bin` is newer than the target.

Thanks! Couldn't seem to get a search to work.

I was hoping the "|"  would explain the behavior that I don't understand, but I don't think it does.

The instructions say to just type "make". My understanding is that without a specified target, the topmost target in the Makefile is used. In this case it is "bin", which has no dependencies, and one action - mkdir. I would think that the Makefile would stop after making that directory as no other actions are given and no dependencies were specified. But it doesn't.

`DEFAULT_GOAL` allows to set an explicit target and keep a everything nicely ordered.

Is something not working when you just type `make`?
Or are you just trying to understand how things work?
In the latter case: you don't need to use make, to build your files, I just use it for small projects because it's super easy.
Anyhow there are other ways you could use this without needing to dive into make:
- as a wrapper - call your actions from a new Makefile target and simply depend on the compiler (that's how I use dub in such projects)
- execute `make` as part of your build script. It will fetch the compiler if non-existent and be a no-op otherwise.

What are you planning to do?

Thanks! (didn't even notice that line)

No

Yes, sorry for the confusion.

I was only trying to understand the Makefile.
