digitalmars.D.learn - Using DUB packages with Meson

reply Dmitry Olshansky <dmitry.olsh gmail.com> writes:
I'm trying to use my new DUB package from Photon, which is 
polyglot project and is built with Meson.

Have anyone worked with DUB packages in Meson? I've found this 
bit of documentation:
https://mesonbuild.com/Dependencies.html#dub

And I did fetch & build but I do not understand how to introduce 
library dependency on a specific DUB package.

I'm going to guess that you need to use the version specifier in the 
package name. Because I'm not seeing anything there to handle it 
specifically.

https://github.com/mesonbuild/meson/blob/master/mesonbuild/dependencies/dub.py

i.e. ``dub build [<package>[ <version-spec>]] [<options...>]``

So use ``package:sub 1.0.2``.

Also I just noticed meson doesn't support shared libraries from dub, so 
something to keep in mind.

Oh, Rikki, you are so helpful. Thanks!

I'm getting closer. I'm stuck with this at the moment:

Found DUB: /home/d.olshanskiy/bin/dub (DUB version 1.31.1, built 
on Mar 12 2023)
ERROR: strand found but it wasn't compiled with ldc
Run-time dependency strand found: NO

src/meson.build:22:0: ERROR: Dependency "strand" not found

Did you compile the library with dub using ldc2?

Yup, I do not have other compilers installed.

What are possible ways to automate such download? Meson knows 
exactly which versions of packages suit to build. Is it possible, 
for example, to get somehow packages list and then download using 
dub fetch?

On dubs end yes, and yes.

$ dub build package version

```
$ dub search knocker
==== registry at https://code.dlang.org/ (fallbacks registry at 
https://codemirror.dlang.org/, registry at https://dub.byt

ecraft.nl/, registry at https://code-mirror.dlang.io/) ====
   knocker (1.0.3) Knocks on ports to open up another. Compatible with 
Knockd.
```

You can also get the entire manifest from dub-registry directly if you 
want it (you shouldn't need it).

 $ dub build package version


I guess I didn't express myself that way

How to get list of packages that can be passed to DUB by this way 
as above?
