#!/bin/bash
# Opt in to building PolyPilot against a local copilot-sdk checkout via ProjectReference.
#
# Usage:
#   ./use-local-sdk.sh [path-to-sdk]    # Create/update Directory.Build.props.local
#   ./use-local-sdk.sh --revert         # Remove the local override
#   ./use-local-sdk.sh --help           # Show help
#
# The SDK path defaults to ../copilot-sdk (a sibling directory). Override with:
#   ./use-local-sdk.sh /path/to/copilot-sdk
#   COPILOT_SDK_PATH=/path/to/copilot-sdk ./use-local-sdk.sh
#
# This is compile-time only: it changes which GitHub.Copilot.SDK project PolyPilot builds
# against. Runtime CLI selection still comes from PolyPilot settings (Global vs Built-in).

Build PolyPilot against a local copilot-sdk checkout from source.

Usage:
  ./use-local-sdk.sh [path-to-sdk]
  ./use-local-sdk.sh --revert

Examples:
  ./use-local-sdk.sh
  ./use-local-sdk.sh /Users/you/Projects/copilot-sdk
  COPILOT_SDK_PATH=/Users/you/src/copilot-sdk ./use-local-sdk.sh

What this does:
  - writes a gitignored Directory.Build.props.local file
  - sets CopilotSdkProjectPath to the local GitHub.Copilot.SDK.csproj
  - runs dotnet restore so PolyPilot starts building the SDK from source

What it does NOT do:
  - it does not modify tracked csproj files or nuget.config
  - it does not change PolyPilot's runtime CLI source (Global vs Built-in)
