Building Claude Code from Source

Step-by-step guide for building the Claude Code CLI from the alesha-pro/claude-code repository — leaked Anthropic Claude Code source code.

Requirements

Linux (Ubuntu 22.04+) or macOS
4GB RAM, 4 CPU cores, 30GB disk
Bun >= 1.3
Git

What do Etcd, Consul, and Zookeeper do?
- Service Registration:
  - Host, port number, and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
- Service Discovery:
  - Ability for client application to query the central registry to learn of service location.
- Consistent and durable general-purpose K/V store across distributed system.
  - Some solutions support this better than others.
  - Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
Centralized locking can be based on this K/V store.

Download docker-compose.yml to dir named sentry
Change SENTRY_SECRET_KEY to random 32 char string
Run docker-compose up -d
Run docker-compose exec sentry sentry upgrade to setup database and create admin user
(Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
Run docker-compose restart sentry
Sentry is now running on public port 9000

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;
