The Function.h include was simply unused, I was partly dropping the bits
that would've depended on it. Protocol.h is used, but it should really
be included from handle.h.
I'm trying to make the LSP look more like the rest of the toolchain. I'm
trying to separate the handlers from the transport layer, and remove the
multiple inheritance aspect. Also fixing some style issues, switching to
`Map`, and removing an unnecessary copt.
I'm using `Context` for the central object for consistency with other
portions of the toolchain. In order to get the `handle_*` files working,
I'm using LLVM's registry class. It has a quirk that I can't register
two registries in the same cpp file, so there are two one-line cpp
files.
In order to help show the delta (or lack thereof) for actual
implementation, I've copied server.cpp over handle_* and undone that in
two commits. See the third and fourth commits on the PR history for
that.
This is in anticipation of making the integer value store be customized
heavily. I'd like to extract it from the common code when doing that, so
first disentangling them here without any intended change in
functionality or behavior to enable that.
I've tried to update `#include`s to be as minimal as I can and added a
few missing includes spotted in the process.
I've split the test for value store to include what was easy focused on
just the value store templates rather than the unified shared value
stores.
This might surface some opportunities for adding more tests, but for
this PR, just doing the minimal restructuring.
Removes the separate language server binary; I'm not sure we need to
provide it. Instead, `carbon language-server` is added as a subcommand.
Moves //language_server to //toolchain/language_server. Splits into a
trivial language_server.h, and a substantive server.h. I wasn't sure
about a better name, but wanted the split similar to check/check.h,
lex/lex.h, etc. At the same time, the class is probably going to be a
little big so not a good fit to through into just a cpp file.
This fixes some style issues with the language server class, but
generally I'm trying to not address things here in order to keep it
simpler.
