atl.chat

Unified chat infrastructure for All Things Linux: IRC, XMPP, web, and protocol bridges.

Architecture

Monorepo layout:

apps/
├── unrealircd/     # UnrealIRCd 6.x server
├── atheme/         # IRC services (NickServ, ChanServ, OperServ, MemoServ)
├── webpanel/       # UnrealIRCd web admin
├── prosody/        # XMPP server
├── web/            # Next.js web application
├── bridge/         # Discord↔IRC↔XMPP bridge (in-repo)
├── thelounge/      # Web IRC client (private mode, WebIRC)
└── gamja/          # IRC web client (planned)

Compose fragments in infra/compose/:

• irc.yaml — UnrealIRCd, Atheme, WebPanel
• xmpp.yaml — Prosody
• cert-manager.yaml — Lego (Let's Encrypt)
• bridge.yaml — Discord↔IRC↔XMPP bridge
• thelounge.yaml — The Lounge web IRC client
• networks.yaml — Shared atl-chat network

Quick Start

Prerequisites

• Docker & Docker Compose
• just — task runner
• Node.js 20+ & pnpm 9+ — for web app (optional)
• uv or Python 3.11+ — for tests (optional)

Setup

git clone https://github.com/allthingslinux/atl.chat.git
cd atl.chat

cp .env.example .env
# Edit .env with your domains, passwords, and TLS paths

# For dev (localhost domains): create overlay from .env.dev.example
cp .env.dev.example .env.dev

just init      # Creates data/ dirs, generates config, dev certs
just dev       # Starts stack with dev profile (Dozzle, localhost domains)

just init runs scripts/init.sh and scripts/prepare-config.sh to:

• Create data/irc/, data/atheme/, data/xmpp/, data/thelounge/, data/certs/
• Substitute .env into UnrealIRCd, Atheme, and Bridge config templates
• Generate dev certs for irc.localhost (if missing)

just dev requires .env.dev (copy from .env.dev.example); it overrides domains for localhost.

First Run

# Development (localhost domains, Dozzle for logs)
just dev

# Production (uses domains from .env)
just prod

just lounge add <name>   # Create user (prompts for password)
just lounge list        # List users
just lounge reset <name> # Reset user password

Task Running

just --list        # All tasks

# Orchestration
just init          # One-time setup
just dev           # Start dev stack
just staging       # Start staging stack
just prod          # Start prod stack
just down          # Stop dev stack
just down-staging  # Stop staging stack
just down-prod     # Stop prod stack
just logs [svc]    # Follow logs (optionally for a service)
just status        # Container status

# Build & test
just build         # Build images
just test          # Run root pytest
just test-all      # Root tests + bridge tests
just lint          # pre-commit run --all-files
just scan          # Security scans (Gitleaks, Trivy)
just clean         # Prune unused Docker resources

Data Layout

All persistent data lives under data/:

data/
├── irc/
│   ├── data/          # UnrealIRCd runtime
│   ├── logs/          # UnrealIRCd logs
│   └── webpanel-data/ # Web panel state
├── atheme/
│   ├── data/          # services.db
│   └── logs/          # atheme.log
├── xmpp/
│   ├── data/          # Prosody SQLite
│   ├── logs/          # Prosody logs
│   └── uploads/       # File uploads
├── thelounge/         # The Lounge user data
└── certs/             # TLS certs (Let's Encrypt layout)
    └── live/<domain>/  # fullchain.pem, privkey.pem

See docs/infra/data-structure.md.

Environment

Single .env at repo root. Copy from .env.example and customize. For dev, also create .env.dev from .env.dev.example.

cp .env.example .env

Key groups:

• IRC: IRC_DOMAIN, IRC_NETWORK_NAME, IRC_OPER_PASSWORD, cloak keys
• TLS: IRC_SSL_CERT_PATH, IRC_SSL_KEY_PATH (paths inside container)
• Atheme: ATHEME_SEND_PASSWORD, ATHEME_RECEIVE_PASSWORD, IRC_SERVICES_PASSWORD
• XMPP: PROSODY_DOMAIN, PROSODY_SSL_*

Config is generated via scripts/prepare-config.sh (run by just init). After editing .env, rerun:

./scripts/prepare-config.sh

Profiles

Profile	Use case
default	Production-style (domains from .env)
dev	Dozzle, localhost domains, extra tools
staging	Staging environment
prod	Production

docker compose --profile dev up -d
just dev    # Uses .env.dev + dev profile
