#  HuggingClaw — Environment Configuration
#  Deploy OpenClaw on HuggingFace Spaces
# ═══════════════════════════════════════════════════════════════════════════
#
#  Usage:
#    Local Docker  →  cp .env.example .env  →  fill in values  →  docker run --env-file .env
#    HF Spaces     →  Set each variable as a "Repository Secret" in Space Settings
#
#  Legend:
#    [REQUIRED]      Must be set, or data persistence will not work
#    [RECOMMENDED]   Strongly recommended for production use
#    [OPTIONAL]      Fine-tune behavior; safe to leave empty
#
# ═══════════════════════════════════════════════════════════════════════════


# ─── SECURITY ─────────────────────────────────────────────────────────────
#
# Password for the Control UI dashboard.
# Visitors can see the UI, but only users with this password can connect
# and control the OpenClaw instance (manage agents, plugins, settings).
#
# [RECOMMENDED]  Default: huggingclaw
#
OPENCLAW_PASSWORD=huggingclaw


# ─── DATA PERSISTENCE ────────────────────────────────────────────────────
#
# HuggingClaw auto-syncs the ~/.openclaw directory to a private HF Dataset
# repo, so your conversations, settings, and credentials survive restarts.
# Without these two variables, all data is lost when the Space restarts.
#
# HuggingFace Access Token with WRITE permission.
# Create one at: https://huggingface.co/settings/tokens
# Scopes needed: read + write access to your repos.
#
# [REQUIRED]
#
HF_TOKEN=hf_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# Target Dataset repository for data backup.
# Format: your-username/repo-name
# Example: your-name/YourSpace-data
#
#   Manual mode (default): create the repo yourself, then set this variable.
#   Auto mode (AUTO_CREATE_DATASET=true): if not set, HuggingClaw derives
#     it from your HF_TOKEN username → "your-username/HuggingClaw-data".
#
# [REQUIRED in manual mode, OPTIONAL in auto mode]
#
OPENCLAW_DATASET_REPO=your-username/HuggingClaw-data

# Whether to auto-create the Dataset repo if it doesn't exist.
# When true: HuggingClaw creates a PRIVATE dataset repo on first startup.
#   If OPENCLAW_DATASET_REPO is not set, the repo name is auto-derived
#   from your HF_TOKEN username (e.g. "your-username/HuggingClaw-data").
# When false (default): you must create the repo manually on HuggingFace
#   and set OPENCLAW_DATASET_REPO yourself.
#
# [OPTIONAL]  Default: false
#
# AUTO_CREATE_DATASET=false

# How often (in seconds) to back up data to the Dataset repo.
# Lower values = safer but more API calls to HuggingFace.
#
# [OPTIONAL]  Default: 60
#
# SYNC_INTERVAL=60


# ─── LLM PROVIDERS ────────────────────────────────────────────────────────
#
# HuggingClaw passes ALL environment variables directly to OpenClaw.
# Any provider that OpenClaw supports works out of the box — just set the
# API key as a Secret in your HF Space settings.
#
# See OpenClaw docs: https://openclawdoc.com/docs/reference/environment-variables
#
# [RECOMMENDED] At least one of the following for AI conversations
#
OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# OPENAI_BASE_URL=https://api.openai.com/v1
# OPENROUTER_API_KEY=sk-or-v1-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# NVIDIA_API_KEY=nvapi-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# ANTHROPIC_API_KEY=sk-ant-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# GOOGLE_API_KEY=AIza...
# MISTRAL_API_KEY=mis-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# COHERE_API_KEY=co-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# Default model for new conversations (must exist in your configured provider).
#
# [OPTIONAL]  Examples: openai/gpt-5-nano, openrouter/deepseek/deepseek-chat:free
#
# OPENCLAW_DEFAULT_MODEL=openai/gpt-5-nano


# ─── PERFORMANCE ──────────────────────────────────────────────────────────
#
# Node.js heap memory limit in MB.
# HF free tier provides 16 GB RAM. Default 512 MB is enough for most cases.
# Increase if you run complex agent workflows or handle large conversations.
#
# [OPTIONAL]  Default: 512
#
# NODE_MEMORY_LIMIT=512


# ─── LOCALE ───────────────────────────────────────────────────────────────
#
# Timezone for log timestamps and scheduled tasks.
#
# [OPTIONAL]  Default: UTC
#
# TZ=Asia/Shanghai


# ─── OPENCLAW (from official docs) ─────────────────────────────────────────
#
# Optional overrides. See https://openclawdoc.com/docs/reference/environment-variables

#  OpenClaw 官方环境变量
# ═══════════════════════════════════════════════════════════════════════════
