# Codeman Universal Installer
# https://github.com/Ark0N/Codeman
#
# Usage: curl -fsSL https://raw.githubusercontent.com/Ark0N/Codeman/master/install.sh | bash
#
# Environment variables:
#   CODEMAN_NONINTERACTIVE=1  - Skip all prompts and accept their defaults
#                               (CI/automation). Required for headless runs
#                               that need system changes (sudo package
#                               installs, AI CLI download); without it those
#                               steps abort instead of running silently.
#   CODEMAN_INSTALL_DIR       - Custom install directory (default: ~/.codeman/app)
#   CODEMAN_SKIP_SYSTEMD=1    - Skip systemd/launchd service setup prompt
#   CODEMAN_NODE_VERSION      - Node.js major version to install (default: 22)
#   CODEMAN_REPO_URL          - Custom git repository URL (default: upstream Codeman)
#   CODEMAN_BRANCH            - Git branch to install (default: master)
#   CODEMAN_HOST              - Preset the network binding and skip the prompt
#                               (e.g. 0.0.0.0 for LAN access, 127.0.0.1 for
#                               local-only; interactive default is 0.0.0.0,
#                               non-interactive default is 127.0.0.1)
#   CODEMAN_PASSWORD          - Preset the dashboard password (skips the
#                               password prompt when binding to the network)
#   CODEMAN_TAILSCALE=1       - Preset the Tailscale choice: bind loopback and
#                               front it with `tailscale serve` HTTPS (skips
#                               the network prompt; never installs Tailscale
#                               in non-interactive runs)
#
# Subcommands:
#   install.sh update     - Update an existing install
#   install.sh uninstall  - Remove services, symlinks and (optionally) data
#   install.sh tailscale  - Set up (or repair) Tailscale serve HTTPS access
#                           for an existing install

# CLI Detection (generic, driven by the generated catalogue above)
# ============================================================================
#
# One implementation for every CLI, replacing nine near-identical
# check_<cli>/get_<cli>_path pairs plus their nine search-path arrays. Those had
# to be extended by hand for each new CLI, and once were not: upstream b6d0f1fa
# is "wire OMP into install.sh's CLI detection (it had none)", where a user with
# only omp installed was told no AI CLI was found and offered Claude Code.
# Adding an entry to stock.ts now wires detection, the install menu and the
# closing reminder in one step.
#
# Probe order per CLI is UNCHANGED and pinned by
# test/install-sh-detection-parity.test.ts: the process PATH first (each declared
# binary name in turn), then each known install path, dir-major.

# `dsh` is the hardest name of the lot: Debian ships an unrelated `dsh`
# (dancer's shell). The server-side resolver settles it by demanding the
# harness's own help banner; detection here only feeds the "you have no AI CLI"
# hint, so the same banner grep is enough — but unlike every sibling probe it
# EXECUTES the candidate, so it must be bounded. </dev/null is load-bearing
# twice over: a foreign binary that blocks on stdin would hang the install, and
# under `curl | bash` a child that reads stdin EATS THE REST OF THIS SCRIPT.
# The timeout (where coreutils ships one; stock macOS has none) bounds a binary
# that ignores EOF, mirroring the server resolver's own EXEC_TIMEOUT_MS.

    # about). `${runner[@]+"${runner[@]}"}` expands to nothing when the array is empty and to

# nobody should be performing on a security-adjacent check. Instead

# one-liners this replaces, and it is why nothing fetched at install time is
# ever executed. The server keeps its own, stricter rule unchanged: it never
# executes an entry's install command at all (see CliDiscovery.install.command

# The recommended remote-access setup: Codeman stays on 127.0.0.1 and
# tailscaled fronts it with a real Let's Encrypt certificate for
# https://<node>.<tailnet>.ts.net, reachable from the user's tailnet only.
# The app side needs zero configuration (.ts.net is in the server's trusted
# host suffixes). All state lives in tailscaled: no marker files, `tailscale
# serve status` is the single source of truth, and `--bg` config persists
# across reboots on its own.
#
# Safety rule for every function here: NEVER `tailscale serve reset` and never
# touch mappings other than 443 -> Codeman's port. Users may have unrelated
# serve config (other ports, other apps) that a reset would destroy.
