* [clangd] Remove 'using namespace llvm' from .cpp files. NFCIlya Biryukov2019-01-071-56/+62
| | | | | | | | The new guideline is to qualify with 'llvm::' explicitly both in '.h' and '.cpp' files. This simplifies moving the code between header and source files and is easier to keep consistent. llvm-svn: 350531
* [clangd] Namespace style cleanup in cpp files. NFC.Sam McCall2018-10-201-32/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Standardize on the most common namespace setup in our *.cpp files: using namespace llvm; namespace clang { namespace clangd { void foo(StringRef) { ... } And remove redundant llvm:: qualifiers. (Except for cases like make_unique where this causes problems with std:: and ADL). This choice is pretty arbitrary, but some broad consistency is nice. This is going to conflict with everything. Sorry :-/ Squash the other configurations: A) using namespace llvm; using namespace clang; using namespace clangd; void clangd::foo(StringRef); This is in some of the older files. (It prevents accidentally defining a new function instead of one in the header file, for what that's worth). B) namespace clang { namespace clangd { void foo(llvm::StringRef) { ... } This is fine, but in practice the using directive often gets added over time. C) namespace clang { namespace clangd { using namespace llvm; // inside the namespace This was pretty common, but is a bit misleading: name lookup preferrs clang::clangd::foo > clang::foo > llvm:: foo (no matter where the using directive is). llvm-svn: 344850
* [clangd] Refactor JSON-over-stdin/stdout code into Transport abstraction. ↵Sam McCall2018-10-171-0/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | (re-land r344620) Summary: This paves the way for alternative transports (mac XPC, maybe messagepack?), and also generally improves layering: testing ClangdLSPServer becomes less of a pipe dream, we split up the JSONOutput monolith, etc. This isn't a final state, much of what remains in JSONRPCDispatcher can go away, handlers can call reply() on the transport directly, JSONOutput can be renamed to StreamLogger and removed, etc. But this patch is sprawling already. The main observable change (see tests) is that hitting EOF on input is now an error: the client should send the 'exit' notification. This is defensible: the protocol doesn't spell this case out. Reproducing the current behavior for all combinations of shutdown/exit/EOF clutters interfaces. We can iterate on this if desired.
