#!/usr/bin/env bash
# bin/olp-connect — Lightweight client script to connect this machine to a remote
# OLP (Open LLM Proxy). Ported from OCP's `ocp-connect` per ADR 0010 § Phase 4
# D68-D70 charter; uses /health.anonymousKey when the remote operator opted in
# via `auth.advertise_anonymous_key: true` (ADR 0011).
#
# Authority:
#   - ADR 0010 (Phase 4 charter — D68 line: client-side IDE auto-config)
#   - ADR 0011 (anonymous-key deployment-context limits — trusted-LAN invariant)
#   - OCP `ocp-connect` v1.3.0 (prior-art reference)
#
# Why bash (not Node like `olp` CLI):
#   olp-connect MUST run on CLIENT machines that may not have a recent Node
#   installed (parents' laptops, work machines, Raspberry Pi). bash + curl +
#   python3 give maximum portability; this script does not import any OLP
#   Node modules.
#
# Dependencies: bash >=4, curl, python3 (for /health JSON parsing).
#
# Install:
#   curl -fsSL https://raw.githubusercontent.com/dtzp555-max/olp/main/bin/olp-connect -o olp-connect
#   chmod +x olp-connect
#
# Or via npm/npx (once `npm install -g olp` is run on a machine that has Node):
#   olp-connect <ip>
#
# Or run directly via curl-pipe:
#   curl -fsSL https://raw.githubusercontent.com/dtzp555-max/olp/main/bin/olp-connect | bash -s -- <host-ip>

olp-connect — Connect this machine to a remote OLP (Open LLM Proxy)

Configures OPENAI_BASE_URL + OPENAI_API_KEY in your shell rc file (and macOS
launchctl env / Linux systemd user env), then detects installed IDEs (Cline,
Continue.dev, Cursor, Aider, OpenClaw, Claude Code) and prints / writes the
provider-specific configuration each needs.

Usage:
  olp-connect <host-ip> [options]
  olp-connect --help
  olp-connect --version

Options:
  --port PORT       Port OLP listens on (default: 4567 — OLP v0.4.0+ default;
                    set 3456 if connecting to a pre-D60 OLP install)
  --key API_KEY     OLP API key (from `olp-keys keygen` on the server). When
                    omitted, the script reads /health.anonymousKey (if the
                    server opted in via auth.advertise_anonymous_key=true) or
                    prompts interactively.
  --no-system-env   Skip macOS launchctl setenv / Linux systemd env writes;
                    only update shell rc files.
  --dry-run         Print everything the script would do without modifying
                    any file or setting any env var.
  --version         Print version and exit
  --help, -h        Show this help

Examples:
  olp-connect 192.168.1.10
  olp-connect 192.168.1.10 --port 8080
  olp-connect 192.168.1.10 --key olp_AbcDef1234...
  olp-connect 100.64.0.5 --dry-run

Requires:
  bash, curl, python3 (for /health JSON parsing)

Exit codes:
  0   success
  1   bad arguments / unknown flag / missing required value
  2   connectivity or auth failure / smoke test failure

Authority: ADR 0010 § Phase 4 D68-D70; ADR 0011 (anonymous-key trusted-LAN
invariant — when --key is auto-resolved from /health.anonymousKey, this
deployment MUST be on a trusted LAN).
