 Hi,

 I would like to know how to specify dmd or ldc compiler and

 Thanks in advance.

 You can't [1]. You can specify the compiler to use only on the 
 dub command line via `--compiler=`.

 [1] https://code.dlang.org/package-format?lang=json

Any reason you couldn't, say, specify the compiler version in the 
dub.sdl, and dub would build it (and use it) using the regular 
.dub/packages mechanism?

Same should work for dub itself. Treat the current dub/dmd as a 
bootstrap compiler instead of the main compiler.

You can use Toolchain requirements 
(https://dub.pm/package-format-sdl.html#toolchain-requirements) to 
specify the compiler. But building the specific compiler version 
(bootstrapping) is not implemented I think.

Also the default compiler can be set in settings.json which can 
be located e.g. in the project folder(next version of dub).

Kind regards

You could build a Makefile (or similar) around dub which ensures 
the exact compiler version gets downloaded.
Here's a template I use for this purpose:
