How to use clangd C/C++ LSP in any project

tl;dr: If you want to just know the method, skip to How to section

Clangd is a state-of-the-art C/C++ LSP that can be used in every popular text editors like Neovim, Emacs or VS Code. Even CLion uses clangd under the hood. Unfortunately, clangd requires compile_commands.json to work, and the only way to painlessly generate it is to use CMake.

But what if I tell you you can quickly hack your way around that, and generate compile_commands.json for any project, no matter how compilcated? I have used that way at work for years, originaly because I used CLion which supported only CMake projects - but now I use that method succesfully with clangd and Neovim.

Method summary

Basically what we need to achieve is to create a CMake file that will generate a compile_commands.json file with information about:

Intro

This is a simple guide on how to automate UK lights with a Shelly 1 by installing the shelly 1 relay into the ceiling pendant which has both permanent live, neutral and a switched live back from the wall switch.

These steps are from my own experience making my lighting "smart" but also user friendly (it works via a wall switch!). This simple guide will go through replacing an a normal ceiling pendant with one with room for a Shelly 1. If you have a ceiling light with a bigger base it's even easier.

Warning Electrical regulations must be followed by law. If you are not a competent person under the regulations do not attempt electrical work. https://www.diydoctor.org.uk/projects/electrical_safety.htm
