Invoke haxe in cwd

[kevinresol]

Fixes lix-pm/lix.client#72

[Gama11]

But why? We already specify --cwd, which seems to work fine for local Haxelib repos.

(and that is also how what the language server does for display requests)

[kevinresol]

When lix is installed, the haxe command does not point to the haxe compiler binary but haxeshim which is a script that checks for the configured haxe version in .haxerc in cwd and invoke the actual haxe compiler. So it has to be invoked in the correct directory (instead of passing the cwd as an arg).

Anyway I think this is more correct as it mimic the behaviour of running the haxe command in cli manually.

In that case this patch should also be applied there. And perhaps that would solve some lix-related problems.

[Gama11]

Well, what confused me is that it seems to work ok for the language server, but not eval-debugger?

@nadako Is there a particular reason we don't just set the cwd / would tha even work for us?

[kevinresol]

I guess it "works" because it invoked haxe in lix's global scope instead of the project-specified one? Perhaps that's why there are problems sometimes, which might be due to incompatible haxe version with some libraries.

Is there a particular reason we don't just set the cwd

It seems to me that it simply because cwd doesn't matter for the haxe compiler (it is the case if the haxe compiler never access the process's cwd). The --cwd flag is completely irrelevant in this context.

I don't remember ^^ But in general, if we ever want to share haxe server across e.g. workspace folders, we'd still need to do --cmd.

FWIW, Lix users want to use the project's specified haxe version for each workspace. So unless the haxe version are exactly the same they shouldn't be shared.

Anyway, if this helps, I'll just merge it for now. I don't have a Lix setup, so I trust that it works. :)
