Specify dmd or ldc compiler and version in a json dub file?
Hi, I would like to know how to specify dmd or ldc compiler and version in a json dub file. Thanks in advance.

dependencies? I guess I could write it in the readme.
If your code depends on capabilities of a specific D compiler, I
wouldn't depend on build tools for that, I'd make it clear in the
source code via conditional compilation [1]:
---
version (DigitalMars)
{
}
else version (LDC)
{
}
else
{
static assert (0, "Unsupported D compiler");
}
---
There's no equivalent for the frontend version, though AFAIK.
If it's not your code that needs something compiler specific, but
you just want to control which is used, don't use dub as a build
tool, use another (cmake, meson, write your own compilation
"script" in D), and set it's invocation as a prebuildcommand in
the dub package file (make sure dub's source file list is empty).

I'll note that you can specify that dub use a particular D
compiler for building all your own D packages, by creating a file
called .dub/settings.json in your home directory, and putting the
full path to the compiler you want in there, like so:
{
"defaultCompiler": "/home/datapulverizer/ldc-1.3/bin/ldc2"
}
Ldc uses a file like that to make sure the dub binary it comes
with uses ldc, not dmd, so you can look at that file for an
example.
However, it sounds like you want to ensure that all users of a
package are forced to use a particular D compiler, while this
will just make sure that your dub binary will always use the D
compiler you want.

Update: you can at least specify these in the toolchain requirements section: https://dub.pm/package-format-json.html#toolchain-requirements I myself am looking for ways to satisfy these automatically, using a tool like dvm (https://code.dlang.org/packages/dvm) in preBuildCommands.

Bastiaan. In the meantime, the dub settings json could also be placed in the project folder and has precedence. Although I would not recommend to distribute the file as it is meant for your local working computer. Kind regards Andre
