Interactive REPL

deckflow repl                           # Start interactive mode

# In REPL:
deckflow> config show
deckflow> compress presentation.pptx
deckflow> task list
deckflow> exit

🔧 Advanced Usage

JSON Output for Scripting

All commands support --json flag for machine-readable output:

# Get configuration as JSON
deckflow --json config show

# List tasks as JSON
deckflow --json task list | jq '.tasks[0].id'

# Compress and get result as JSON
deckflow --json compress file.zip

Batch Processing

# Process multiple files
for file in *.pptx; do
  deckflow compress "$file"
done

# Or use REPL mode
deckflow repl

Non-blocking Operations

# Start task without waiting
deckflow compress video.mp4 --no-wait

# Check task status later
deckflow task get <task-id>

🔑 Configuration

Configuration is stored in ~/.deckflow/config.json:

{
  "token": "your-auth-token",
  "spaceId": "your-space-id",
  "apiBase": "https://api.example.com/v1"
}

Configuration options:

• token - Authentication token (required)
• spaceId - Workspace/space ID (optional, default: UMYSELF)
• apiBase - API base URL (default: https://app.deckflow.com/v1)
• signURI - Sign-in URI (optional)

🐛 Troubleshooting

"Not configured" error

Make sure you've set your authentication token:

deckflow config set-token <your-token>

# Optionally set space ID (defaults to 'UMYSELF')
deckflow config set-space <your-space-id>

Task timeout

Increase timeout for large files:

deckflow compress large-file.mp4 --timeout 600
