# Environment-based post-commit hook for Git Friends
# This hook uses environment variables for configuration instead of command-line arguments
#
# To use this hook:
# 1. Copy this file to .git/hooks/post-commit
# 2. Make it executable: chmod +x .git/hooks/post-commit
# 3. Source the accompanying .profile file or set the environment variables manually
#
# Environment variables used:
# - GF_HOOK_PATH: Path to the gf-hook binary (required)
# - GF_SERVER_URL: URL of the gf-server (optional, defaults to http://localhost:8080)
# - GF_TOKEN: Authentication token (optional, only needed if server requires auth)
# - GF_CONFIG: Path to git-friends config file (optional)

# Source the git-friends profile if it exists
if [ -f "$HOME/.git-friends.profile" ]; then
    source "$HOME/.git-friends.profile"
fi

# Check if gf-hook path is set
if [ -z "$GF_HOOK_PATH" ]; then
    echo "Error: GF_HOOK_PATH environment variable is not set"
    echo "Please set it to the path of your gf-hook binary"
    exit 1
fi

# Check if gf-hook binary exists
if [ ! -x "$GF_HOOK_PATH" ]; then
    echo "Error: gf-hook binary not found or not executable at: $GF_HOOK_PATH"
    exit 1
fi

# Set default server URL if not provided
GF_SERVER_URL=${GF_SERVER_URL:-"http://localhost:8080"}

# Build the command with optional arguments
GF_HOOK_ARGS="--server-url $GF_SERVER_URL"

# Add token if provided
if [ -n "$GF_TOKEN" ]; then
