gen-compile-commands

Simple utility to generate compile-commands.json based on compile-flags.txt.

Without compile-commands.json clangd can't enumerate project files. While include/symbol resolution works, find references and other features that require full project scanning do not work.

gen-compile-commands uses single compile-flags.txt file as a template for all source files discovered in --src-dir.

Installation

cargo install gen-compile-commands
