digitalmars.D - On Dub

Go puts compiled executables into $GOPATH/bin or $GOBIN and packages in
$GOPATH/pkg which separates nicely downloaded repository clones from
compilation products.

Cargo puts compilation products into the using project tree and not the
~/.cargo tree.

For me, wanting to use ~/.dub, with three different architectures,
having compilation products in that directory is a bad idea. Whilst go

dub should be using the $XDG_CACHE_HOME/dub (or $HOME/.cache/dub if it's not set) for storing build files to abide by XDG standards.

Sönke said once that DUB used to work like Cargo and not have packages installed globally, and then users asked for a change. While I would also like DUB to work like cargo, the pluses and minuses were probably carefully evaluated.

It wouldn't be a very big change to just adhere to $DUBPPATH if it exists, which seems to be your major gripe about Go vs Dub.

My gripe is that Dub is neither Cargo (doesn't have install, compiles in the project) nor Go (installs to a known place determined by environment variable, compiles to a known place =E2=80=93 or a transitory p= lace somewhere temporary). Currently I am favouring the Go way rather than the Cargo way. Obviously SCons and CMake have a far better story on all this making and installing, but they do not do dependency management.

The cargo-like behavior(I believe?) is almost implemented, there's a single issue left that would enable a flag so that dub just stores everything in a .dub/ folder in the current project directory. See this issue https://github.com/D-Programming-Language/dub/issues/319

On reflection the Cargo way of working only works if you clean
everything and rebuild everything every time. The Go way of working
allows to trivially switch the output of the compilation products by a
simple change of environment variable.

Go's way of vendoring does however suck.

Indeed, I allow no executables in /bin /usr/bin unless put there by the system package manager. This is just being sensible. However I have a ~/Built hierarchy in which I put everything I build. With SCons, CMake, Autotools, etc. it is trivially easy to specify a destination location for installation. Go makes things a bit awkward, but their solution is cross-platform and so has some backing and rationale. Cargo doesn't have an install per se, but I bet there is a plugin for that. --=20 Russel. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.winder ekiga.n= et 41 Buckmaster Road m: +44 7770 465 077 xmpp: russel winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder

Well run already runs the binary, so you can just use that `dub run myprog -- args`. Anything that installs binaries to some common `.dub/bin` path will have to deal with colliding binaries, different versions of packages, and w/ shared libraries in the package folders or somewhere else. If you figured out all of this, here is the install command https://github.com/D-Programming-Language/dub/blob/fe02126ea2ca7d58eab31797d4efe4a8b4878c9b/source/dub/commandline.d#L1131.
