• Tool
• Util

• ccls (another C/C++ LSP)

Provides IDE-like features for text editors through Language Server Protocol. Needs compile_commands.json for all the files to enable indexing and stuff. There are several ways to generate it. You can use -MJ flag with clang and concatenate the results into one file. Or use Bear. Or this Python thingie.

• Configuration - clangd
