digitalmars.D.learn - Why I need DUB? Will never DMD don't just use import for import

Why can't I just use: import vibe.vibe; for import packages like 
Nim or Python? Why I still use DUB?

In python you also have pip.

It is possible to use vibe.d (any dub package) without dub but 
you have a few manual steps involved.

Python dont need pip for run script with imported module. Just 
need call python.

Same as for D. You can just use dub for downloading the packages 
and then use DMD with the correct import paths arguments/ 
switches / additional arguments.
The analogy here is the setup.py where you configure your 
dependencies in python.

But you need to install the module beforehand. The Pyhton 
interpreter doesn't fetch modules and install them for you. 
Neither does dmd.

Every dub package is different. Copying files, different script 
hooks (e.g. before generation...), and many more.
This is not in the responsibility of a compiler, but in a package 
manager.

I don't use dub. Just dmd -i after you set up the files in the 
right place.

Not all libraries support that but I only use my own libraries so 
it is fine.

I highly recommend Adam's arsd library (or collection of libraries).
Mostly just single files, with a few that have one or two dependencies,
you just copy the file(s) into your workspace and import them. That's
all.  No need for external tools to manage dependencies, no dependency
hell, just drop the file into your project and go.

arsd does have a dub thingy for those who want it, but I mostly just git
submodule it in my own projects or plain ole copy a couple o' files into
my workspace. No fuss, no muss, no hairy NP-complete dependency graphs,
the way it should be.

Here an example of using gtkd without dub :
ldc2 -I/usr/local/include/d/gtkd-3 -L-lgtkd-3 -L-ldl hello.d
When you run dub with parameters "--verbose" it informs you what 
is going on.

I have not figured out how to use tkd without dub.
It would be nice to know how.

Theoretically an rdmd-like tool can automatically infer 
dependencies from imports (autodub?). But it can also easily 
expose you to a supply chain attack.

sure, use -v flag, this will give you compiler flags and other 
info
```
    dub build -v
```
this will give you extensive build information in json
```
    dub describe
```
also if you don't like dub going internet just add this flag
```
    --skip-registry=all
```
