setup.sh

#!/usr/bin/env bash
# setup.sh — one-shot setup for Anya — GitHub Copilot for your browser.
#
# Bash equivalent of setup.ps1. Installs deps + builds both projects, runs
# the bridge ping smoke test, and registers the Native Messaging host for
# every detected Chromium browser (Edge, Chrome, Chromium, Brave, Vivaldi,
# plus Arc on Windows + macOS).
#
# Supports macOS, Linux, and Windows (Git Bash, MSYS2, Cygwin).
#
# WSL note: inside WSL2, `uname -s` returns "Linux" so this script will
# operate on the WSL Linux side. To install for Windows-host browsers
# from WSL, run setup.ps1 via cmd.exe interop or pwsh.exe instead.
#
# Usage:
#   ./setup.sh [--browsers edge,chrome,...] [--quiet] [--skip-test] [--uninstall]
