Hi everyone,

My name is Ionuț and I am interested in one of the SAOC projects, 
the one about DUB: D's package manager. What I would like to know 
are the parts about git support and C/C++ support. Can you tell 
me which one is more important for the community and what are the 
next steps for SAOC and maybe more details about what exactly is 
already implemented if there is something, in order for me to 
know where to start exactly.

Thank you.

Hi Ionuț,

While I really prefer git support I vote for C/C++ support. I 
heard a lot developers complaining that they can't use dub at all 
due to bad or missing support of building multi language 
applications with Dub.
So far I wasn't in the need of building such applications 
therefore I can't say what exactly is missing and what's the best 
solution would be.

In any case dub should be able to also serve this scenario.

Kind regards
Andre

Also please note, Funkwerk also plan writing a pull request for 
the git support:

Just to clarify, we're going to be doing this if we're going with 
dub as the version resolution tool. This is not totally settled 
yet, and there's internal debate about it due to the amount of 
effort involved. If we're going with it, we'll do git as a 
package supplier, but I'll note that we're on it as a separate 
post when that happens.

I didn't realize git package supplier was a GSOC topic. I didn't 
mean to collide with that effort, and naturally, as any company 
does we'd prefer if somebody else did the work. ;)

FWIW just adding a git package supplier wouldn't be an adequate 
SAoC topic as it definitely doesn't take three months to get 
done. However, it's one of the many areas where dub could be 
improved and students are free to pick up such ideas and combine 
them into their project proposal.

Hi Ionuț,

thanks a lot for your interest!

As you probably saw on 
https://github.com/dlang/projects/issues/3, there are quite a few 
potential projects.

As Andre already answered on the git steps, let me give try to 
give an answer for C/C++ support:

- start with https://github.com/dlang/dub/wiki/DEP5
- look at how other package managers deal with this (e.g. cargo)
- study dub's existing code
   - you probably have to change the Compiler interface to 
"DCompiler" 
(https://github.com/dlang/dub/blob/master/source/dub/compilers/compiler.d) and
introduce a C/C++ compiler abstraction.

- start with a simple example (e.g. linenoise). Instead of L14 in 
the dub.sdl 
(https://github.com/MartinNowak/linenoise/blob/master/dub.sdl#L14), dub should
be able to handle this more elegantly
- provide more advanced examples and settings (cflags, cppflags)

I hope this helps to get you started. Please feel free to ask 
more questions here, on the DUB repository or on Slack/IRC.

Good luck!

IMHO, dub should receive some love before another thing is added 
on top.

The issue list alone is long enough to give you sleepless nights.
 From what I have seen so far, much of dub is very tightly coupled 
together.
IMO, splitting it up into more distinct parts (sub packages) 
would be a more valuable step (aka. dub as a library).
For example:
I recently was trying to add dip25 and dip1000 to all packages on 
code.dlang.org.
And found myself writing a dub.json and dub.sdl parser.

What I wanted to do was.
```
auto c = loadConfig("pathToDubProject");
c.addDflag("dip1000");
c.addDflag("dip25");
saveConfig("pathToDubProject, c);
```
But I couldn't.

I hope I just overlook this something, but that in itself is not 
a good sign with
regards to the documentation, or my skills. Hopefully, the first 
though.

That being said, I think working on dub is extremely valuable for 
D.


As talk is cheap. I'm by no means a dub expert, but having used 
it quite
extensively even before joining Symmetry, I'm willing/able to at 
least co-memtor
a dub project. Giving it is selected as a project for SAOC.
