No extensions in Atom/VS Code provides linting

[Hossain Adnan]

I'm making this thread to share my frustration in setting up 
Dlang development tools using VS Code in Ubuntu 19.04.

I have a small ongoing project using GTK and Rust but Rust's BC 
had been giving me trouble in borrowing mutable references across 
the different widgets (for example button click handlers). So I 
had created a branch and wanted to start rewriting it in D/GtkD 
before the project gets too complex. What I didn't know:

1. The builtin package for dub is broken:
`#apt install dub`, it installs just fine but as soon as I tried 
initiating a project dub throws a runtime error and throws some 
demangled symbol name. It looks like a problem in Debian unstable 
and the known issue hasn't been fixed in a while.

This prompted me to install dlang tools from the "install.sh" 
script. It does a fine job except that it could automate setting 
up PATH by itself, but no worries it's not a big issue.

2. VS Code extensions don't work:
Once I installed dmd and dub from the script file I opened up VS 
Code, there are (as far as I understand) two mainstream 
extensions for Dlang: Dlang using DLS and Code-D. Great.

When I installed DLS plugin, it said something about "installing 
DLS"... and that's about it. Formatting works but there's no 
linting whatsoever.

Code-D -- same outcome, no linting.

So I opened up issues on both the repos. Why does it have to be 
so difficult to set up and get started with coding? Not to start 
a flame-war or something but Rust sets a gold-standard of how 
tooling should be -- they should just work! All I had to do with 
Rust, is install the RLS plugin and that's it -- Linting, 
formatting, highlights -- all just work.
