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 thehandle_*
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.
