ccls

ccls is a fork of cquery (originally written by Jacob Dufault), a C/C++/Objective-C language server.

code completion (with both signature help and snippets)
definition/references, and other cross references
call (caller/callee) hierarchy, inheritance (base/derived) hierarchy, member hierarchy
symbol rename
document symbols and approximate search of workspace symbol
hover information
diagnostics
code actions (clang FixIts)
preprocessor skipped regions
semantic highlighting, including support for rainbow semantic highlighting

It makes use of C++17 features, has less third-party dependencies and slimmed-down code base. Cross reference features are strenghened, (see [wiki/FAQ]). It currently uses libclang to index C++ code but will switch to Clang C++ API. Refactoring and formatting are non-goals as they can be provided by clang-format, clang-include-fixer and other Clang based tools.
