dlangui will be fetched if you make it a dependency of your project.

When you run dub init on your project, it will ask for dependencies, 
just type dlangui in there.

Thanks, I tried that but when I add the import dlangui in the 
beginning it doesn't work. I wanted to just type import dlangui 
in the beginning of the file so I can call the dlangui functions.

D uses dub and code.dlang.org to fetch dependencies (similar to python 
or other ecosystems).

If you are using dub to build your project, just add dlangui as a 
dependency, and you can then import and use it. This goes in your 
dub.json or dub.sdl file. See documentation here: 
http://code.dlang.org/getting_started

If you want to build the dlangui library directly and install it on your 
own without dub, you would need to download the source (probably from 
github) and build it using dub.

When I said without using dub, I meant without using dub to build your 
project. You still need to use dub to build the library.

It finally worked, but I can't just compile it normally, I have 
to use dub run, I wish it were something simple that I just 
download into the folder and then use an import statement and 
then compile it like any other program. I wish it were as simple 
as using std.stdio for example.

Unfortunately your stuck with Dub if you want to use D. It's an 
awful experience compared to Python and other scripting 
languages, so I understand what you're saying, but most people 
around here think Dub is the way to go.

It's not true that you're stuck with dub.  And I'm not among the people
who think dub is the way to go (though it's true that that's a minority
opinion around here).  Where I have a choice, my own D projects do not
use dub.

I have one project that uses dub because it's based on vibe.d, but I
mostly avoid needing to use dub by creating an empty dub project in a
subdirectory whose sole purpose is to declare a dependency on vibe.d.
Then I build that once with dub, and outside in my real project I just
link directly to the produced artifacts. (The exact path(s) to the dub
products can be extracted from the output of `dub -v`. This can probably
be automated and translated into your build system of choice, though I
haven't quite gone that far yet.)  Then I don't need to use dub except
when upgrading the dub-dependent library.

I find dub almost completely unusable for normal development, because:

(1) it requires network access,

(2) it's dog-slow compared to how fast the actual D compiler runs (it
tries to do dependency updating every single time it runs, even when all
you've done is to change 1 line in your code),

(3) it either does not support incremental builds, or else is so bad at
doing it that it takes about just as long as a full build from scratch;

(4) it's not configurable enough to meet my build needs -- e.g., it's
completely unable to handle my current Android project that involves
compiling Java code, D code, GLSL code, and cross-compiling / linking /
building an APK, plus compile and link an X11 test driver on the host
PC, which involves invoking a different (non-cross) compiler with
different libraries and a different set of source files -- dub's build
spec simply isn't capable of expressing the level of configurability
required to do all of this;

(5) it imposes a source tree hierarchy that conflicts with what I need
(Android SDK's APK tools expect a particular directory structure that
does not fit into dub's model).


While I appreciate the amount of effort it took to develop and deploy
dub, I am sorry to say that it falls far short of my expectations and I
can't see myself using it in any meaningful sense in the foreseeable
future.  Using it as a dependency puller for vibe.d is about as far as I
will go, unfortunately.

Many of dub's limitations, AFAICT, are inherent to its design and
architecture, so I don't see any easy way to fix these problems either,
short of rewriting it from scratch (and I have no inclination to take on
something that big at this time).

Atila Neves has also created his own D-based build system that
reportedly is much superior to dub.  You might want to look into that as
well.

This is still a build system though. It might have advantages 
over Dub, but I think the OP wants to avoid build systems 
altogether. Someone coming from a scripting language wants to add

import foo;

to their program and not think about package foo further. There's 
no obvious reason it can't be done that way in D, but the C/C++ 
foundation of this community leads to a mindset that it's wrong, 
because you need to be able to set all kinds of configuration 
options, guarantee reproducible builds, etc. All of which are of 
no importance to someone using D as a scripting language.

It is trivial, really. Just download the files to your import 
path and `dmd -i`. Only hard part is the modules need to be 
arranged such that dmd -i will find it... and the dub package 
layout isn't compatible with it... lol.

But my libs are :P


We could probably write a downloader that reads module 
declarations and arranges them in an installed libs folder. Very 
simplified "install library" thing whose initial setup could set 
the dmd conf stuff so it just works (or wraps dmd slightly to add 
-I and -i to build it)...

Do it!  That would be a welcome convenience for importing 3rd party code
where the full machinery of dub isn't necessary.

Me neither, I think it's a lot of work for little benefit and 
doesn't seem all that easy to use either. I rather use rdmd using 
-I flags.

Stop bashing dub. Its completely fine for me. I don't get what OP 
mean by "simple" but:

dub init
add package name
dub run

... doesn't look "not simple" to me.

It will pay some of us if you explain more on how to us dub. To 
me dub is too difficult to us and is not user friendly. It is not 
every body who is interested in Dlang is in a country with strong 
internet connection. A tutorial on how to use dub will really 
help. I don't need a link as i have gone through them but did not 
help me. How i wish dlang tools will be as simple and user 
friendly as the language itself.

It's actually not a bad idea to be able to "install" libraries like you 
have your compiler installed. It could be done with the infrastructure 
that's there already. Would be cool for playing around with toy projects 
without having to initialize a dub project. There is the ability to 
include the dub file in the source file itself, but that may be too 
complex for your taste.

For most people who want to have their projects depend on others, there 
is the need to specify the projects, how they should be built, and what 
versions, etc. Which is why dub is used to build most things.

Whenever you import a module from a folder somewhere else than 
your project, you need to pass the location to the compiler with 
the -I flag. The reason std.stdio works from everywhere is 
because if you go to <D-installation-folder>/windows/bin/sc.ini 
(assuming you use Windows and dmd), you will find:

[Environment]
DFLAGS="-I% P%\..\..\src\phobos" 
"-I% P%\..\..\src\druntime\import"

This will add the -I flag with the phobos location by default.
If you run:
dub --verbose --force
You will see how dub invokes the compiler. If you look at the 
compiler flags, you will likely find something like this:

-I..\..\..\AppData\Roaming\dub\packages\<package name>\source

What you could do is locate the package, move it to a folder of 
your choice, and add an import to that location to your sc.ini. 
The Gtkd UI-framework actually prescribes such a global install:
https://github.com/gtkd-developers/GtkD/wiki/Installing-on-Windows

I don't know how comfortable you are doing this, it may be easier 
to just use dub like it's intended.

This could actually be a neat feature of dub: a global install of 
a dependency.
