clangd-db-picker.nvim

A tiny helper for C/C++ projects: pick a compile_commands.json, generate a repo-local .clangd that points to it, and restart clangd with the right --target, --sysroot, and -isystem include dirs derived from your compiler.

Features

• Telescope picker to choose among multiple compile_commands.json in a repo
• Infers compiler, language, target, sysroot, and system include paths
• Writes a minimal .clangd with CompilationDatabase + flags
• Restarts clangd for the repository automatically

Requirements

• Neovim 0.10+
• telescope.nvim
• A working toolchain (clang/gcc) in $PATH
