@lpil I presume you're referring to [dogma](https://github.com/lpil/dogma). Then perhaps the solution is to add a checker for `dogma`, and leave the `elixir` checker as it is?

Great. Now, in order for this to actually happen, one of you guys can either post a PR, or explain for the non-initiated (i.e. for yours truly): * how syntastic...

Well, I suppose this leaves the other option. Working PRs are welcome.

Please refer to #699. New feature will be added health permitting, if / when I can get myself together to re-start working at syntastic. In the mean time you can:...

No errors to display --> no `loclist` --> no error window. :) Coming up with an older list just to keep the window there doesn't make much sense as far...

Ah, I see. I don't think there is any easy way to achieve that. The way we handle opening and closing the error window is already pretty fragile.

That breaks in two ways: it opens the error window even if it was previous empty, and it populates the loclist with the wrong set of locations if there _are_...

One more thing: if all errors are fixed and the previous list of locations was generated by Syntastic, you don't want to resurrect the errors as zombies. I don't see...

The second patch addresses only the first problem I noted above, opening the error window even if it's empty. It doesn't seem to address the other ones.

I agree, Syntastic should be able to coexist peacefully with pre-existing loclists. There might be a way to achieve that (we already do it for signs), but as far as...
