Have you considered invoking dub instead of dmd if there's a
dub.json/.sdl file? I imagine when people use
"preBuildCommands" to generate code, for example, the linter
might report false positives. Same goes for custom D versions
(e.g. `version(Have_foo) { ... }`).
No I haven't considered using dub. Does dub allow the
processing of a single file from the project without
generating code? Note that you don't want to build the whole
project upon every activation of the linter, because of speed
but also because of errors that do not apply to the file in
the current view.
Not sure about that, would need some investigating. From what I
can tell, dub docs have improved quite a bit in the past year.
I had a look, and I don't think it does support this.
There's also the --single feature of dub:
https://code.dlang.org/advanced_usage Such files may not work
correctly with this linter at this time I presume.
I don't see why not?
Sorry, let me rephrase. What I meant is that, with dub, you can
add dependencies (e.g. some http library) and define D
versions. So even tho it's only a single file, the invocation
of dmd alone is not sufficient to understand the code
completely.
Then I guess "dub describe" would report that dependency. We
could add support for that, when a file starts with a dub
shebang. The plugin does not detect versions from dub yet, but I
am not sure it needs to. IIANM then the code inside version()
blocks is required to be syntactically correct, and it could well
be that dmd will bark at syntax errors inside version blocks even
when they are not selected. Possibly some errors relating to
symbol resolution and mixins may still go undetected though.
If there are multiple versions, you would ultimately want to lint
all available ones? This can become a bit hairy.
I guess it would be most useful if I created some test cases
and documented them.
Yes.
All in all they way this plugin works is a great idea! The
more it knows about the full commandline of the resulting dmd
invocation, the more accurate it is.
If you have a case where it isn't sufficient, I am interested
to see how it can be improved. You can experiment with it as
explained here:

Haven't experimented with it yet so it's all just speculation
so far. I'm quite interested in a dub linter. As far as I can
tell from a first glance at your plugin code, it doesn't seem
too complicated.
You are right, and starting a new linter is easy as well, and
well documented:

I think I will investigate whether dub is suitable for this
endeavor and implement that aspect of the plugin myself. If I
have enough time in the coming days, of course. Will keep you
posted!
Have fun,
Bastiaan.
