REPL Interface
==============

The REPL (Read-Eval-Print Loop) provides a feature-rich command-line interface for interacting with Pantheon agents and teams.

Quick Start
-----------

Start the REPL with default settings:

.. code-block:: bash

   pantheon cli

You'll see a welcome message and prompt. Type your message and press Enter to chat with the agent.

.. code-block:: text

   ╭─ Pantheon REPL ─╮
   │ Type /help for commands │
   ╰──────────────────────────╯

   > Hello! What can you help me with?

Starting Options
----------------

.. code-block:: bash

   # Use a specific team template
   pantheon cli --template data_research_team

   # Set memory directory
   pantheon cli --memory-dir ./my_chats

   # Resume a previous chat
   pantheon cli --chat-id abc123

   # Quiet mode (less output)
   pantheon cli --quiet

Key Features
------------

Syntax Highlighting
~~~~~~~~~~~~~~~~~~~

Code in responses is automatically highlighted:

.. code-block:: text

   > Write a Python hello world

   Here's the code:

   ```python
   print("Hello, World!")
   ```

File Viewer
~~~~~~~~~~~

View files with syntax highlighting using ``/view``:

.. code-block:: text

   > /view src/main.py

This opens a full-screen viewer with:

- Line numbers

- Page navigation (Space, Ctrl-F/B)

See :doc:`file-viewer` for details.
