Configuring a development environment for Bun can take 10-30 minutes depending on your internet connection and computer speed. You will need ~10GB of free disk space for the repository and build artifacts.

If you are using Windows, please refer to this guide

Using Nix (Alternative)

A Nix flake is provided as an alternative to manual dependency installation:

nix develop

hi, i'm daniel. i'm a 16-year-old high school senior. in my free time, i hack billion dollar companies and build cool stuff.

about a month ago, a couple of friends and I found serious critical vulnerabilities on Mintlify, an AI documentation platform used by some of the top companies in the world.

i found a critical cross-site scripting vulnerability that, if abused, would let an attacker to inject malicious scripts into the documentation of numerous companies and steal credentials from users with a single link open.

(go read my friends' writeups (after this one))

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 easiest way to painlessly generate it is to use CMake.

For simple projects you can try to use Bear - it will capture compile commands and generate compile_commands.json. Although I could never make it work in big projects with custom or complicated build systems.

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.

// stb_c_lexer.h 0.01 -- public domain Sean Barrett 2013
// lexer for making little C-like languages with recursive-descent parsers
//
// This file provides both the interface and the implementation.
// To instantiate the implementation,
//      #define STB_C_LEXER_IMPLEMENTATION
// in *ONE* source file, before #including this file.
//
// The default configuration is fairly close to a C lexer, although
// suffixes on integer constants are not handled (you can override this).

this will deadlock the process if we run it in same process as js

There are many tutorials on the web that explain how to build a
simple hello world in C without the libc on AMD64, but most of them
stop there.

I will provide a more complete explanation that will allow you to
build yourself a little framework to write more complex programs.
