This doesn't seem like the right solution to the problem - the correct
solution, in my opinion, is to have a build tool/package manager handle
this, not the compiler.
Problems I see:
* Remote server gets hacked, everyone using the library now
executes malicious code
This liability is not different from a traditional setup.
* Remote source changes how it is built, your code suddenly breaks and
has to be updated, rather than being handled automatically
This is a deployment issue affecting this approach and any other relying
on downloading stuff.
* Adds a lot of unnecessary bloat and/or dependency on external modules
+ Want to compress source code? dmd now depends on decompression libs
Indeed, I think compression will indeed be commonly requested. The same
has happened about Java - initially it relied on downloading .class
files, but then jar files were soon to follow.
It's been a feature asked in this forum, independently of downloads. A
poster implemented a complete rdmd-like program that deals with .zip files.
+ Want to use git? dmd now depends on git
Not if the server can serve files, or if you use a different tool.
+ Remote code uses new compression method that an older dmd doesn't
support
If compression handling is needed, dmd can standardize on it just like
jar files do.
* Remote server is down - build takes forever while waiting
So does downloading or building with another tool.
+ Make dmd time out after a couple of seconds - build fails
So would build directed with any other tool.
* Makes the assumption that the build machine is has internet
connectivity, if it doesn't building suddenly gets a lot more
complicated
Fair point.
* Source code changes location, build breaks unless a redirect is
possible - if it changes protocol it's useless
See my answer with a central repo.
My understanding is that you find automated download during the first
build untenable, but manual download prior to the first build
acceptable. I don't see such a large fracture between the two cases as
you do.
