Open Source C++ Language Servers

C/C++/ObjC language server supporting cross-references, hierarchies, completion, and semantic highlighting. It has a global view of the code base and supports a lot of cross-reference features, see wiki/FAQ. It starts indexing the whole project (including subprojects if exist) parallelly when you open the first file, while the main thread can serve requests before the indexing is complete. Saving files will incrementally update the index. Hierarchies, call (caller/callee) hierarchy, inheritance (base/derived) hierarchy, member hierarchy. Symbol rename. Document symbols and approximate search of workspace symbol. Hover information. Diagnostics and code actions (clang FixIts). Semantic highlighting and preprocessor skipped regions.

The Verible project's main mission is to parse SystemVerilog (IEEE 1800-2017) (as standardized in the SV-LRM) for a wide variety of applications, including developer tools. It was born out of a need to parse un-preprocessed source files, which is suitable for single-file applications like style-linting and formatting. In doing so, it can be adapted to parse preprocessed source files, which is what real compilers and toolchains require. The spirit of the project is that no-one should ever have to develop a SystemVerilog parser for their own application, because developing a standard-compliant parser is an enormous task due to the syntactic complexity of the language. Verible's parser is also regularly tested against an ever-growing suite of (tool-independent) language compliance tests. A lesser (but notable) objective is that the language-agnostic components of Verible be usable for rapidly developing language support tools for other languages.

This is a new generation of SQL (Structured query language) Server which is targeted to serve on a Virtual Appliance. Hybrid SQL Server is targeted to run on VirtualBox from SunMicrosystems.

C/C++ language server supporting multi-million line code base, powered by libclang. Emacs, Vim, VSCode, and others with language server protocol support. Cross-references, completion, diagnostics, semantic highlighting, and more. cquery is a highly-scalable, low-latency language server for C/C++/Objective-C. It is tested and designed for large codebases like Chromium. cquery provides accurate and fast semantic analysis without interrupting workflow. cquery implements almost the entire language server protocol and provides some extra features to boot. cquery is able to respond to queries quickly because it caches a huge amount of information. When a request comes in, cquery just looks it up in the cache without running many computations. As a result, there's a large memory overhead. For example, a full index of Chrome will take about 10gb of memory. If you exclude v8, webkit, and third_party, it goes down to about 6.5gb.

Language server implementation for GLSL. Currently, this LSP implementation can be interfaced with using either HTTP or Studio. You can run glslls to use an HTTP server to handle IO. Alternatively, run glslls --stdin to handle IO on stdin. lsp-mode has this language server integrated into the core. This assumes you have glsl-mode installed.

This is a feature-rich nix language server interoperating with C++ nix.
