digitalmars.D - On Dub

Dub has a "run" capability, but apparently no "install" one. Also it

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
and cargo have different solutions to this, both are better than what
dub currently appears to do. Unless I am missing something=E2=80=A6

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.

S=C3=B6nke was doing things right, and the user who moaned were and are

Dub should behave either like Go or Cargo, or something equally good at
separating downloaded source from compilation products. The current
state is a blocker to Dub usage.

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.

If Dub was changed to use environment variables to specify where
compilation products went rather than just putting it in ~/.dub, and
there was a way of installing executables to a place specified by an
install variable, then things would be nicer.

 somewhere temporary).

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.

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.

I think the reason for the missing "install" command is that most 
packagers will claim that software should only be installed through the

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.

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
