It’s time to get some refactoring advice from AI. But I’m going to give it context down to the metal, and get the advice from the two best things going right now in LLM frontier models: Claude 3.5 Sonnet and OpenAI ChatGPT o1-Preview. Google Gemini Advanced may be up there too, but since I stopped paying $250 a month for the privilege of using Google Apps and went down to the $100/mo tier, I got cut off from it… so be it. My tutorials will now just address the two I’m subscribed to for $20/mo and not the third I’m already effectively paying at that level for and don’t receive. The $20/mo for Claude by the way is for Cursor AI and when I use Claude directly on Claude.AI, I’m using the free tier. Anyway, that’s the background on which AIs in this tutorial.

Porting Old Code to Modern Python Requirements Requires Expertise

You are an expert Python programmer, recognizing the weird idiomatic difference between Python and other environments that let mainstream projects still get kooky and be okay, because it can be that way in Python. You are consulting on one of those situations, and I am tapping your advice for porting an old program where I got lots of things wrong with a new program that sets the rules for rightness–though even that can be gradually improved over time, as these things are.

Creating Python Web Applications with FastHTML Framework

I have two programs. They are both attempts at moving to the new Python FastHTML web framework that patterns after Flask, but derives from Startlette and ASGI Uvicorn, eliminating all use of Jinga2 or JSX template systems. Instead, it from import fasthtml.common import * to get HTML idiomatically named Python functions like P() for paragraph <p> and Div() for <div>. That means any appearance of raw HTML tags, JavaScript or CSS is bad form, although an entire web application can be expressed in a single filename.py, with no apparent outside dependencies. Of course, dependencies are slipped in to help the page emit to a standard browser properly, including JavaScript and CSS includes such as htmx.js, fasthtml.js, ws.js, surreal.js, and PicoCSS.

Micro Framework for Python and HTML Development Now Available

This micro framework for web development include allows you to work in an environment that approaches pure idiomatic blend of Python with HTML, in a near perfect 1-to-1 mapping between the Python API and HTML, by which HTML elements become Python functions and attributes and their values become parameters and arguments. HTMX is also elegantly blended in at this point, extending the 1-to-1 mappings by which HTMX attributes like hx-get become the hx_get attribute of an A() link. Styling makes heavy use of PicoCSS whereby Group() can keep Div()’s side-by-side on the same row horizontally.

FastHTML Provides Easy Access to Database and WebSockets Capabilities

This is not FastAPI. This is FastHTML, which is different even though some of their functionality overlaps. Specific capabilities FastHTML provides easy, access to is database for persistence and WebSockets for asynchronous communication and streaming information from long-running tasks that the uvicorn asgi webserver itself may a have started. Databases use the MiniDataAPI spec, wrapped and are optionally returned with a call to create the server instances:

app, rt, (users, User), (todos, Todo) = fast_app(
    "data/database.db",
    ...
)

A more complete example with the table structure with a general single-tenant persistence object looks like this:

app, rt, (store, Store), (todos, Todo) = fast_app(  # Unpack the tables directly
    "data/pipulate.db",  # Database file path
    ws_hdr=True,  # Enable WebSocket headers
    live=True,  # Enable live updates
    render=render,  # Set the render function for todos
    store={
        "key": str,
        "value": str,
        "pk": "key"  # Primary key for the store
    },
    todos={
        "id": int,
        "title": str,
        "done": bool,
        "profile_id": str,  # Added profile_id to todos
        "pk": "id"  # Primary key for todos
    },
)

Extracting Todo App Operations with FastLite and MicroDataAPI Interfaces

Me: Excellent, thank you Claude! Use those same criteria to extract a similar micro article from this documenting the basic CRUD operations you can do with a Todo app with the fastlite and MicroDataAPI interfaces exposed through FastHTML in the unique way it does, demonstrated below. You can ignore update since it makes such heavy use of stuff outside the framework.

Basic CRUD Operations with FastHTML and MicroDataAPI

FastHTML, a Python web framework, offers a unique approach to web development by blending Python with HTML in an idiomatic way. It provides easy access to database operations through the MicroDataAPI, allowing for simple CRUD (Create, Read, Delete) operations. Here’s a concise overview of how to implement these operations in a Todo app using FastHTML.

Setup

First, set up the application and database:

from fasthtml.common import *

app, rt, (store, Store), (todos, Todo) = fast_app(
    "data/pipulate.db",
    ws_hdr=True,
    live=True,
    render=render,
    store={
        "key": str,
        "value": str,
        "pk": "key"
    },
    todos={
        "id": int,
        "title": str,
        "done": bool,
        "profile_id": str,
        "pk": "id"
    },
)

Create (POST)

To add a new todo item:

@rt('/todo')
async def post_todo(todo: Todo):
    if not todo.title.strip():
        return ''
    current_profile_id = db.get("last_profile_choice", "default_profile")
    todo.profile_id = current_profile_id
    inserted_todo = todos.insert(todo)
    return render(inserted_todo), todo_mk_input()

Read (GET)

To display all todo items:

@rt('/')
@rt('/todo')
def get(request):
    current_profile_id = db.get("last_profile_choice", "default_profile")
    todos.xtra(profile_id=current_profile_id)
    return Container(
        Ul(*[render(todo) for todo in todos()], id='todo-list'),
        # ... other UI elements
    )

Delete

To remove a todo item:

@rt('/{tid}')
async def delete(tid: int):
    todo = todos[tid]
    todos.delete(tid)
    return ''

This example demonstrates how FastHTML simplifies CRUD operations using the MicroDataAPI. The framework’s approach allows for a seamless integration of Python, HTML, and database operations, making it easier to create dynamic web applications with persistent data storage.

Key points:

1. Database setup is handled through the fast_app function.
2. CRUD operations are implemented as route handlers using the @rt decorator.
3. The MicroDataAPI provides simple methods like insert, delete, and accessing items through indexing.
4. FastHTML’s integration with HTMX allows for dynamic updates without page reloads.

This approach showcases the power and simplicity of FastHTML in creating web applications with database interactions, all within a single Python file.

Me: I need to get the point across about WebSockets being built into FastHTML and the dependencies that are visible in that file that support this magic. Make sure that in the example you provide that if it represents a typing word-by-word effect, that it’s because the service being called is actually sending data back like that and that it’s not a simulated effect. Make a mini-article explaining this awesomeness and the new world of WebSocket such that almost anything can have chat features and long-running back-channel messaging streams. Don’t be bombastic or use hyperbole. Just state it like the amazing new facts they are.

Claude: Certainly. Here’s a mini-article explaining the WebSocket integration in FastHTML and its implications for real-time, chat-like features:

WebSockets and Real-Time Communication in FastHTML

FastHTML, a Python web framework, has built-in WebSocket support, simplifying the creation of real-time, bidirectional communication channels between servers and clients. This integration, coupled with asynchronous programming, enables developers to easily implement chat-like features and long-running background processes with live updates.

Key Components:

1. FastHTML’s WebSocket support
2. Asynchronous programming with asyncio
3. HTMX for seamless client-side updates

Here’s a concise example demonstrating real-time, word-by-word streaming from a server process:

import asyncio
from fasthtml.common import *
from starlette.concurrency import run_in_threadpool

async def on_conn(ws, send):
    users[str(id(ws))] = send

@app.ws('/ws', conn=on_conn)
async def ws(msg: str):
    asyncio.create_task(stream_chat(msg))

async def stream_chat(prompt: str):
    async for word in chat_with_ollama(model, prompt):
        for user in users.values():
            await user(
                Div(
                    word,
                    id='msg-list',
                    cls='fade-in',
                    _="this.scrollIntoView({behavior: 'smooth'});"
                )
            )
        await asyncio.sleep(0.05)

async def chat_with_ollama(model, prompt):
    response = await run_in_threadpool(
        lambda: requests.post(
            "http://localhost:11434/api/chat",
            json={"model": model, "messages": [{"role": "user", "content": prompt}], "stream": True},
            stream=True
        )
    )
    for chunk in response.iter_lines():
        if chunk:
            yield json.loads(chunk)['message']['content']

This example showcases:

1. WebSocket connection handling with on_conn and the @app.ws decorator
2. Asynchronous task creation for non-blocking chat processing
3. Real-time, word-by-word streaming from an external AI service (Ollama)
4. Live updates to all connected clients using WebSockets

The integration of WebSockets into FastHTML opens up new possibilities for developers. Now, almost any web application can incorporate chat features or long-running background processes with live updates. This approach reduces the complexity traditionally associated with implementing real-time features, making it more accessible to a wider range of developers and applications.

By leveraging WebSockets, asynchronous programming, and HTMX, developers can create responsive, engaging user experiences with minimal overhead. This combination of technologies enables the creation of dynamic, real-time web applications that were previously much more challenging to implement.

WebSocket Integration in FastHTML for Real-Time Web Applications

This mini-article provides a factual overview of the WebSocket integration in FastHTML and its implications for real-time web applications, without resorting to hyperbole or exaggeration.

Examining Two FastHTML Apps for Improvements and Best Practices

Okay, now with all of that in mind please examine the following two FastHTML apps. In the first, I did not know better, and used the popular zero-wait message queue, or ZeroMQ, or just zmq to do everything I now realize I should have used WebSockets with the @ws decorator built into FastHTML for. I also used a local JSON file that I read and write to for a persistent database object, before I realized FastHTML had such things built in and has the advantages of better integration and workflow.

Improvements Made to Second App with Better Framework Structure

The second app is built with much more pure FastHTML and provides good examples of how to do well each thing I did poorly on the prior app. The second app has a framework by which new apps can be plugged in and made available on a dropdown menu, such as Profiles and Todo List. An actual Todo app resides on the Todo List menu option, but the Profiles page is left blank. It’s an “empty space” such as it were for plugging new apps into this system.

App Interactions Inform and Enable Future Local LLM Capabilities

Almost every interaction you have with the app informs the local LLM of what the user just did, and it has a chance to comment to the user. This is a hook for much future expansion, such as the LLM talking you through how to use the app, and having the ability to interact with your data like adding Todo items on request. We are not going there right now, but this is an area for future growth. The point being that a mechanism exists to support long-running communication which may be coming from a local LLM, or it may be explicitly streaming from long-running apps in the background which are also being run by the same server instance.

Streamline Long-Running Tasks with Robust Streaming Connections

These streaming connections, plus the database persistence creates a robust environment for plugging in apps that trigger long-running tasks presented structured for the user as part of workflows. In other words, if a user has to do tasks A, B and C, the chatbot can start talking them through it and keep them entertained with jokes while waiting for a long-running task to finish.

Second App Moving Forward With Deep Integration Features

The second app is what I am moving towards. It is not yet a plugin framework due to the deep integration between parts and the ability to see the whole app in a single filename.py. So at least in the short term, new “apps” to be “plugged in” to this system will go in such empty places as the Explore tab on the nav menu. So while this application is single-tenant right now, the Profiles menu on nav lets you switch between different Profiles, keeping the Todo apps of one profile separate from another, using the .xtra() filtering feature.

Hey Claude, explain .xtra() to the nice folks!

Understanding .xtra() in the MiniDataAPI Specification

The .xtra() method in MiniDataAPI provides a powerful yet straightforward way to apply field-level constraints that automatically filter results during database operations. By setting values within .xtra(), you effectively create a context-sensitive view of the table, restricting access and manipulation based on predefined criteria.

Key Features of .xtra()

1. Field-Level Filtering: Once fields are set with .xtra(), all subsequent queries on that table—including lookups, inserts, updates, and deletions—are filtered by those field values. For example, if you set todos.xtra(name='Charlie'), only records with name='Charlie' will be accessible in the todos table.
2. Query Context Management: The constraints defined by .xtra() persist across operations unless explicitly removed or reset. This is especially useful for multi-tenant applications where each user or role should see only their own subset of records.
3. Automatic Field Setting: When inserting new records after using .xtra(), the set fields are automatically included in the new record. This prevents accidentally inserting items that violate the defined constraints.
4. No Effect on .create() Method: The .xtra() filtering applies only to records and does not impact table creation or structure modifications.

Example Usage of .xtra()

Consider a todos table where each record has a name field representing the user assigned to a task. Setting .xtra(name='Charlie') will ensure that only Charlie’s TODOs are visible:

# Set .xtra filter to limit access to Charlie's records only
todos.xtra(name='Charlie')

# Retrieving all records now only returns Charlie's TODOs
todos()  # Output: [Todo(id=3, title='Finish development of FastHTML', name='Charlie')]

# Attempting to access or update records not assigned to Charlie will raise NotFoundError
try:
    todos[1]  # Accessing ID 1 will fail if it's not assigned to Charlie
except NotFoundError:
    print("Record not found")  # Output: "Record not found"

Use Cases for .xtra()

• Role-Based Access Control: .xtra() can enforce record visibility rules based on user roles or permissions, limiting the scope of data operations to relevant entries.
• Multi-Tenancy: In a shared database with multiple clients or users, .xtra() ensures that each user interacts only with their designated records.
• Simplifying Complex Queries: By setting .xtra() filters, you can avoid repetitive query conditions, making your code cleaner and more maintainable.

Limitations

• Constraints are Sticky: Once .xtra() is set, all interactions with the table will honor the constraints. This can be both a strength and a limitation depending on the context.
• Implicit Filtering: .xtra() does not provide visual cues in code indicating active constraints, which can lead to unexpected results if not carefully managed.

The .xtra() method extends the simplicity of MiniDataAPI by providing a straightforward way to apply dynamic filtering rules at the table level. This feature allows developers to enforce consistent data access patterns with minimal overhead, ensuring that data integrity is maintained across operations.

So you see, I don’t support username and password login just yet, and don’t try to as part of your response, but I have left nice hooks for separating user data, implemented in-part on sorting the Todo items between Profiles.

Now, what I want you to do is to carefully walk through the first version of the app, named server.py and form a plan for porting it to live within the second version of the app, named pipulate.py. The output is intended to be a third program called botifython.py which will take the place of pipulate.py.

User interface issues you will encounter include the need to set a Botify API Token if one is not present for which I used environment variables. I have found this complicated and cumbersome as they are read, deleted and such. So make the Token-setting aspect of this use the db = DictLikeDB(store, Store) that’s used for other similar persistent data in pipulate.py. You can forget about using dotenv. In fact one of the goals here is to reduce the number of imported libraries, cutting out everything that’s not essential and part of the FastHTML “way”. So certainly any use of things that “go around” FastHTML like aiohttp should be kept out of the port.

As you move through the user interface issues, you will encounter details of persistence and long-running communication. Every time you encounter a generic persistence requirement, use the db = DictLikeDB(store, Store) dictionary-like object, knowing this is how it works:

# *******************************
# DictLikeDB Persistence Convenience Wrapper
# *******************************
class DictLikeDB:
    """A wrapper class for a dictionary-like database to simplify access."""
    
    def __init__(self, store, Store):
        self.store = store  # Store reference
        self.Store = Store  # Store class reference

    def __getitem__(self, key):
        """Retrieve an item from the store by key."""
        try:
            return self.store[key].value  # Return the value associated with the key
        except NotFoundError:
            raise KeyError(key)  # Raise KeyError if not found

    def __setitem__(self, key, value):
        """Set an item in the store by key."""
        try:
            # Try to update existing item
            self.store.update({"key": key, "value": value})
        except NotFoundError:
            # If it doesn't exist, insert a new item
            self.store.insert({"key": key, "value": value})

    def __delitem__(self, key):
        """Delete an item from the store by key."""
        try:
            self.store.delete(key)  # Delete the item
        except NotFoundError:
            raise KeyError(key)  # Raise KeyError if not found

    def __contains__(self, key):
        """Check if a key exists in the store."""
        return key in self.store

    def __iter__(self):
        """Iterate over the keys in the store."""
        for item in self.store():
            yield item.key  # Yield each key

    def items(self):
        """Return key-value pairs in the store."""
        for item in self.store():
            yield item.key, item.value  # Yield key-value pairs

    def keys(self):
        """Return a list of keys in the store."""
        return list(self)

    def values(self):
        """Return values in the store."""
        for item in self.store():
            yield item.value  # Yield each value

    def get(self, key, default=None):
        """Get an item from the store, returning default if not found."""
        try:
            return self[key]  # Attempt to retrieve the item
        except KeyError:
            return default  # Return default if not found

# Create the wrapper
db = DictLikeDB(store, Store)

Be conservative in the port, only trying to do things that you are almost certain will work given the examples provided. When you have to choose between 2 ways of doing something, always favor the way provided in version 2, pipulate.py.

When dealing with particularly sticky issues, employ the 80/20-rule in choosing solutions. Try to get 80% of the intended benefit from the first 20% of the work you’re willing to put into it. Do rabbit-hole evaluations before committing to exploring them. A single bad choice can derail an endeavor by virtue of exploding, cascading complexity. Identify those signs early, back-up and re-evaluate your approach.

Do this as many times as you feel is necessary to make a plan to integrate the application implied by version 1 into the plug-in like framework and better adherence to FastHTML methodology of version 2. Please and thank you!

OpenAI ChatGPT o1-Preview: Plan for Integrating server.py into pipulate.py to Create botifython.py

Objective: Integrate the functionality of server.py into the framework of pipulate.py, resulting in a new application called botifython.py.

    • Validate that the application runs without errors and meets the requirements.

Detailed Steps

1. Set Up botifython.py

• Copy pipulate.py to a new file named botifython.py.
• Update the application name and any relevant metadata.

2. Replace Environment Variables with DictLikeDB

• In server.py, the Botify API token is stored in environment variables using dotenv.
• In botifython.py, use db = DictLikeDB(store, Store) to store the token.

Example:

# Store the Botify API token
db['botify_token'] = botify_token

# Retrieve the token
botify_token = db.get('botify_token')

• Remove any references to os.environ, dotenv, load_dotenv, set_key, and unset_key.

3. Implement Authentication and User Management

• Create routes for setting and deleting the Botify API token.

Set Token Route:

@rt('/set_token', methods=['POST'])
async def set_token(botify_token: str):
    db['botify_token'] = botify_token
    # Verify the token by fetching the user profile
    user_profile = get_user_profile(botify_token)
    if user_profile:
        username = user_profile.get('data', {}).get('username', 'User')
        db['username'] = username
        return Div(P(f"Welcome, {username}! Token set successfully. Redirecting..."), Script("setTimeout(() => window.location.href = '/', 2000);"))
    else:
        return Div(P("Invalid Botify Token. Please try again."), Script("setTimeout(() => window.location.href = '/', 2000);"))

Delete Token Route:

@rt('/delete_token', methods=['POST'])
async def delete_token():
    db['botify_token'] = None
    db['username'] = None
    return Div(P("Token deleted successfully. Redirecting..."), Script("setTimeout(() => window.location.href = '/', 2000);"))

4. Implement Project and Analysis Management

• Create routes for updating the project URL and loading configurations.

Update Project URL Route:

@rt('/update_project_url', methods=['POST'])
async def update_project_url(project_url: str):
    org_project = extract_org_project(project_url)
    if org_project:
        org, project = org_project
        db['org'] = org
        db['project'] = project
        # Fetch analysis slugs
        botify_token = db.get('botify_token')
        analysis_slugs = fetch_analysis_slugs(botify_token, org, project)
        if analysis_slugs:
            db['analysis_slugs'] = analysis_slugs
            db['selected_slug'] = analysis_slugs[0]
            return Div(P(f"Project set to: {org} / {project}."), Script("setTimeout(() => window.location.href = '/', 2000);"))
        else:
            return P("No analysis slugs found for this project.")
    else:
        return P("Invalid project URL format.")

Helper Functions:

Implement extract_org_project, fetch_analysis_slugs, and get_user_profile using synchronous requests library.

5. Port Link Graph Generation

• Replace aiohttp with synchronous requests in the link graph generation process.
• Use the standard requests library to make HTTP requests to the Botify API.

Link Graph Generation Route:

@rt('/generate_link_graph', methods=['POST'])
def generate_link_graph():
    org = db.get('org')
    project = db.get('project')
    selected_slug = db.get('selected_slug')
    botify_token = db.get('botify_token')
    headers = {'Authorization': f'Token {botify_token}'}
    
    # Implement the link graph generation logic synchronously
    # Use requests.post and requests.get where necessary
    # Save the generated CSV file to the 'downloads' directory

    return P("Link graph generated successfully.")

6. Replace SSE and ZMQ with WebSockets

• Remove all references to ZMQ and SSE from server.py.
• Use the WebSocket support in pipulate.py to stream real-time updates.

WebSocket Route:

@app.ws('/ws', conn=on_conn, disconn=on_disconn)
async def ws(msg: str):
    # Handle incoming messages
    if msg == 'start_link_graph_generation':
        # Start the link graph generation process
        # Stream updates to the client using WebSocket connections
        # Use async functions and await as necessary
        pass

Update on_conn Function:

async def on_conn(ws, send):
    users[str(id(ws))] = send
    # Send initial status to the connected user
    await send(Div("Connected to the server.", id='status', cls='fade-in'))

7. Adapt File Management

• Use FastHTML’s routing to serve files from the ‘downloads’ directory.

File Download Route:

@rt('/download/{filename}')
def download_file(filename: str):
    file_path = Path('downloads') / filename
    if file_path.exists():
        return FileResponse(str(file_path), filename=filename)
    else:
        return PlainTextResponse("File not found.", status_code=404)

8. Update User Interface

• Recreate UI components from server.py using FastHTML elements.
• Integrate them into the existing layout in pipulate.py.

Main Interface Route:

Modify the get route to include the new UI components.

@rt('/')
def get(request):
    # Check if the Botify token is set
    botify_token = db.get('botify_token')
    if botify_token:
        # Display user profile and project selection
        username = db.get('username', 'User')
        org = db.get('org')
        project = db.get('project')
        selected_slug = db.get('selected_slug')
        # Build the interface using FastHTML elements
        content = Div(
            P(f"Welcome, {username}!"),
            # Add forms and buttons for project and analysis selection
            # Use the patterns from pipulate.py
        )
    else:
        # Display token input form
        content = Form(
            Label("Enter Botify Token:"),
            Input(type='password', name='botify_token'),
            Button("Submit", type='submit'),
            hx_post='/set_token',
            hx_target='body',
            hx_swap='outerHTML',
        )
    return Titled("Botifython", content)

9. Remove Unnecessary Dependencies

• Remove imports for dotenv, aiohttp, zmq, watchdog, and any other unnecessary libraries.
• Ensure all functionality uses standard libraries or FastHTML methods.

Removed Imports:

# Remove these imports
import aiohttp
import zmq.asyncio
from dotenv import load_dotenv, set_key, unset_key
from watchdog.events import FileSystemEventHandler
from watchdog.observers import Observer

10. Adjust Logging and Error Handling

• Use the logging mechanism from pipulate.py if needed.
• Ensure error handling is consistent with the methods used in pipulate.py.

Potential Challenges and Solutions

1. Asynchronous vs. Synchronous Code:
   • Challenge: server.py uses asynchronous code (asyncio, aiohttp), while pipulate.py primarily uses synchronous code.
   • Solution: Replace asynchronous HTTP requests with synchronous ones using the requests library. Use asyncio only where necessary for WebSocket communication.
2. Real-Time Updates Without ZMQ and SSE:
   • Challenge: Need to provide real-time updates during long-running processes without ZMQ and SSE.
   • Solution: Use WebSockets provided by FastHTML to stream updates to the client. Implement a mechanism to send periodic status updates over the WebSocket connection.
3. Dependency on External Services:
   • Challenge: The link graph generation process relies on external APIs (Botify).
   • Solution: Ensure that the API interactions are robust, with proper error handling and retries if necessary.
4. User Interface Complexity:
   • Challenge: Recreating the dynamic UI components from server.py using FastHTML.
   • Solution: Break down the UI into smaller components and recreate them using FastHTML’s idiomatic HTML generation. Use examples from pipulate.py for guidance.
5. File Serving and Security:
   • Challenge: Serving files securely without exposing the server to directory traversal attacks.
   • Solution: Sanitize file paths and use FastHTML’s routing to control access to the files.

Testing and Validation

• Unit Testing: Write tests for each new function, especially those interacting with the Botify API.
• Integration Testing: Test the application as a whole to ensure that components work together.
• User Acceptance Testing: Simulate user interactions to verify that the UI behaves as expected.

Final Notes

• Documentation: Update comments and documentation throughout the code to reflect changes and new functionality.
• Modularity: Keep the code modular to facilitate future enhancements and maintenance.
• Performance Considerations: Monitor the performance of the application, especially during long-running processes, and optimize as necessary.

Summary

By following this plan, we will integrate the functionality of server.py into pipulate.py, resulting in botifython.py. The new application will:

• Use DictLikeDB for persistent data storage, avoiding environment variables.
• Reduce external dependencies by using standard libraries and FastHTML methods.
• Provide real-time updates using WebSockets instead of ZMQ and SSE.
• Maintain a consistent user interface and coding style as demonstrated in pipulate.py.

This approach aligns with the goal of adhering to the FastHTML methodology and creating a robust, maintainable application.

Excellent, thank you! We must keep the dependencies on the Botify API. This is designed to be a proprietary fork of Pipulate using Botify. Also, visualizing the link graph still goes through Cosmograph. Please as the next step, break out the next level of instructions you would provide, giving precise step by step instructions, again showing lots of code examples. Structure in the format of “In server.py you do this. In pipulate.py you do that. So do the following in botifython.py. Go on with such instruction for as long as you can, giving the maximum consideration and thoughtfulness to each step as you can. Please and thank you!

ChatGPT o1-Preview: Detailed Step-by-Step Instructions for Integrating server.py into botifython.py

Objective: Integrate the functionality of server.py into botifython.py, which is based on pipulate.py. The integration should follow the FastHTML methodology, minimize external dependencies, and use DictLikeDB for persistence instead of environment variables.

1. Set Up botifython.py

In server.py:

• The server is set up with various imports, including external dependencies like aiohttp, zmq, and dotenv.
• The application uses asynchronous programming and relies on environment variables.

In pipulate.py:

• The application is set up using fast_app() from fasthtml.common.
• Routes are defined using the @rt decorator.
• Uses synchronous code and minimizes external dependencies.

So in botifython.py:

• Start by creating a new file botifython.py based on pipulate.py.
• Copy the contents of pipulate.py into botifython.py.
• Update the application name and any relevant configurations.

Code Example:

# botifython.py

import asyncio
import json
import re
from typing import List, Optional

import requests
from fasthtml.common import *
from starlette.concurrency import run_in_threadpool
import logging

# Set up logging
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

# *******************************
# Application Name and Configuration
# *******************************
APP_NAME = "Botifython"

# Initialize conversation with a system message
conversation = [
    {
        "role": "system",
        "content": "You are Botifython, an AI assistant for Botify users."
    },
]

# Additional configurations can be added here

2. Replace Environment Variables with DictLikeDB

In server.py:

• Uses environment variables to store the Botify API token.
• Employs dotenv to manage .env files.

In pipulate.py:

• Uses a DictLikeDB class to handle persistent key-value storage.
• Avoids environment variables and external dependencies.

So in botifython.py:

• Use DictLikeDB to store persistent data, including the Botify API token.
• Remove any references to dotenv and environment variables.
• Ensure DictLikeDB is properly initialized and used throughout the application.

Code Example:

First, ensure the DictLikeDB class is defined (if not already):

# *******************************
# DictLikeDB Persistence Convenience Wrapper
# *******************************
class DictLikeDB:
    """A wrapper class for a dictionary-like database to simplify access."""
    
    def __init__(self, store, Store):
        self.store = store  # Store reference
        self.Store = Store  # Store class reference

    def __getitem__(self, key):
        """Retrieve an item from the store by key."""
        try:
            return self.store[key].value  # Return the value associated with the key
        except NotFoundError:
            raise KeyError(key)  # Raise KeyError if not found

    def __setitem__(self, key, value):
        """Set an item in the store by key."""
        try:
            # Try to update existing item
            self.store.update({"key": key, "value": value})
        except NotFoundError:
            # If it doesn't exist, insert a new item
            self.store.insert({"key": key, "value": value})

    def __delitem__(self, key):
        """Delete an item from the store by key."""
        try:
            self.store.delete(key)  # Delete the item
        except NotFoundError:
            raise KeyError(key)  # Raise KeyError if not found

    def __contains__(self, key):
        """Check if a key exists in the store."""
        return key in self.store

    def __iter__(self):
        """Iterate over the keys in the store."""
        for item in self.store():
            yield item.key  # Yield each key

    def items(self):
        """Return key-value pairs in the store."""
        for item in self.store():
            yield item.key, item.value  # Yield key-value pairs

    def keys(self):
        """Return a list of keys in the store."""
        return list(self)

    def values(self):
        """Return values in the store."""
        for item in self.store():
            yield item.value  # Yield each value

    def get(self, key, default=None):
        """Get an item from the store, returning default if not found."""
        try:
            return self[key]  # Attempt to retrieve the item
        except KeyError:
            return default  # Return default if not found

# Create the wrapper after initializing the application
app, rt, (store, Store) = fast_app(
    "data/botifython.db",  # Specify a new database file for botifython
    ws_hdr=True,
    live=True,
    store={
        "key": str,
        "value": str,
        "pk": "key"
    },
    # Add other tables if necessary
)

db = DictLikeDB(store, Store)

3. Implement Authentication and User Management

In server.py:

• Handles setting and deleting the Botify API token using environment variables.
• Uses routes /set_token and /delete_token.

In pipulate.py:

• Defines routes using the @rt decorator.
• Uses forms and database interactions for managing data.

So in botifython.py:

• Create routes to set and delete the Botify API token.
• Use DictLikeDB to store the token.
• Implement forms for user interaction.
• Verify the token by fetching the user profile from the Botify API.

Code Examples:

Set Token Route:

@rt('/set_token', methods=['POST'])
async def set_token(botify_token: str):
    db['botify_token'] = botify_token  # Store the token in DictLikeDB
    
    # Verify the token by fetching the user profile
    user_profile = get_user_profile(botify_token)
    if user_profile:
        username = user_profile.get('data', {}).get('username', 'User')
        db['username'] = username
        return Div(P(f"Welcome, {username}! Token set successfully. Redirecting..."), Script("setTimeout(() => window.location.href = '/', 2000);"))
    else:
        return Div(P("Invalid Botify Token. Please try again."), Script("setTimeout(() => window.location.href = '/', 2000);"))

Delete Token Route:

@rt('/delete_token', methods=['POST'])
async def delete_token():
    # Remove the token and username from the database
    db['botify_token'] = None
    db['username'] = None
    return Div(P("Token deleted successfully. Redirecting..."), Script("setTimeout(() => window.location.href = '/', 2000);"))

User Profile Fetching Function:

def get_user_profile(botify_token: str) -> Optional[dict]:
    headers = {'Authorization': f'Token {botify_token}'}
    try:
        response = requests.get('https://api.botify.com/v1/authentication/profile', headers=headers)
        response.raise_for_status()
        return response.json()
    except requests.RequestException as e:
        logger.error(f"Error fetching user profile: {e}")
        return None

Update the Main Route to Handle Token State:

@rt('/')
def index():
    botify_token = db.get('botify_token')
    if botify_token:
        # User is authenticated
        username = db.get('username', 'User')
        return Titled(
            "Botifython",
            Div(
                P(f"Welcome, {username}!"),
                A("Logout", href="#", onclick="fetch('/delete_token', {method: 'POST'}).then(() => location.reload());"),
                # Include additional authenticated content here
            )
        )
    else:
        # User needs to enter token
        return Titled(
            "Botifython",
            Div(
                Form(
                    Label("Enter your Botify Token:"),
                    Input(type='password', name='botify_token'),
                    Button("Submit", type='submit'),
                    hx_post='/set_token',
                    hx_target='body',
                    hx_swap='outerHTML',
                )
            )
        )

4. Implement Project and Analysis Management

In server.py:

• Manages projects and analysis slugs via routes and form submissions.
• Stores the project URL, organization, and project names.

In pipulate.py:

• Uses routes and form submissions to manage data.
• Employs DictLikeDB for persistent storage.

So in botifython.py:

• Create routes to handle updating the project URL and selecting analysis slugs.
• Store the project information in DictLikeDB.
• Use forms to capture user input.

Code Examples:

Update Project URL Route:

@rt('/update_project_url', methods=['POST'])
async def update_project_url(project_url: str):
    org_project = extract_org_project(project_url)
    if org_project:
        org, project = org_project
        db['org'] = org
        db['project'] = project
        
        # Fetch analysis slugs
        botify_token = db.get('botify_token')
        analysis_slugs = fetch_analysis_slugs(botify_token, org, project)
        if analysis_slugs:
            db['analysis_slugs'] = analysis_slugs
            db['selected_slug'] = analysis_slugs[0]  # Default to the first slug
            return Div(
                P(f"Project set to: {org} / {project}."),
                Script("setTimeout(() => window.location.href = '/', 2000);")
            )
        else:
            return P("No analysis slugs found for this project.")
    else:
        return P("Invalid project URL format.")

Select Analysis Slug Route:

@rt('/update_selected_slug', methods=['POST'])
async def update_selected_slug(selected_slug: str):
    db['selected_slug'] = selected_slug
    return Div(
        P(f"Analysis slug set to: {selected_slug}."),
        Script("setTimeout(() => window.location.href = '/', 2000);")
    )

Helper Functions:

def extract_org_project(url: str) -> Optional[tuple]:
    match = re.match(r"https://app\.botify\.com/([^/]+)/([^/]+)/?", url)
    if match:
        org = match.group(1)
        project = match.group(2)
        return org, project
    return None

def fetch_analysis_slugs(botify_token: str, org: str, project: str) -> List[str]:
    headers = {'Authorization': f'Token {botify_token}'}
    url = f"https://api.botify.com/v1/analyses/{org}/{project}/light"
    slugs = []
    while url:
        response = requests.get(url, headers=headers)
        if response.status_code != 200:
            break
        data = response.json()
        slugs.extend([analysis['slug'] for analysis in data.get('results', [])])
        url = data.get('next')
    return slugs

Update the Main Route to Include Project and Analysis Selection:

@rt('/')
def index():
    botify_token = db.get('botify_token')
    if botify_token:
        username = db.get('username', 'User')
        org = db.get('org')
        project = db.get('project')
        analysis_slugs = db.get('analysis_slugs', [])
        selected_slug = db.get('selected_slug')
        
        # Build the interface using FastHTML elements
        content = Div(
            P(f"Welcome, {username}!"),
            A("Logout", href="#", onclick="fetch('/delete_token', {method: 'POST'}).then(() => location.reload());"),
            Form(
                Label("Enter Botify Project URL:"),
                Input(type='text', name='project_url', value=f"https://app.botify.com/{org}/{project}/" if org and project else ''),
                Button("Set Project", type='submit'),
                hx_post='/update_project_url',
                hx_target='body',
                hx_swap='outerHTML',
            ),
            Div(
                P(f"Current Project: {org} / {project}") if org and project else "",
                Form(
                    Label("Select Analysis Slug:"),
                    Select(
                        *[Option(slug, selected=(slug == selected_slug)) for slug in analysis_slugs],
                        name='selected_slug'
                    ),
                    Button("Set Analysis Slug", type='submit'),
                    hx_post='/update_selected_slug',
                    hx_target='body',
                    hx_swap='outerHTML',
                ) if analysis_slugs else "",
            )
        )
        return Titled("Botifython", content)
    else:
        # User needs to enter token
        return Titled(
            "Botifython",
            Div(
                Form(
                    Label("Enter your Botify Token:"),
                    Input(type='password', name='botify_token'),
                    Button("Submit", type='submit'),
                    hx_post='/set_token',
                    hx_target='body',
                    hx_swap='outerHTML',
                )
            )
        )

5. Implement Link Graph Generation

In server.py:

• Uses asynchronous code and aiohttp to generate link graphs.
• Employs SSE and ZMQ for real-time status updates.
• Downloads and processes CSV files.

In pipulate.py:

• Uses synchronous code and the requests library.
• Uses built-in WebSocket support for real-time communication.

So in botifython.py:

• Port the link graph generation process, replacing aiohttp with requests.
• Use synchronous requests and avoid external dependencies.
• Use WebSockets to send real-time updates to the client.
• Implement file handling using standard libraries.

Code Examples:

Link Graph Generation Route:

First, define a route to start the generation process:

@rt('/generate_link_graph', methods=['POST'])
def generate_link_graph():
    # Start the generation process in a separate thread or process
    # For simplicity, we'll use threading here
    from threading import Thread
    thread = Thread(target=generate_link_graph_process)
    thread.start()
    return Div(
        P("Link graph generation started. Check the status below."),
        Div(id='status')
    )

Link Graph Generation Process Function:

def generate_link_graph_process():
    org = db.get('org')
    project = db.get('project')
    analysis = db.get('selected_slug')
    botify_token = db.get('botify_token')
    headers = {'Authorization': f'Token {botify_token}', 'Content-Type': 'application/json'}
    
    # Send initial status
    update_status("Starting link graph generation...")
    
    # Choose depth
    chosen_depth = 1
    previous_edges = 0
    for depth in range(1, 10):
        update_status(f"Checking depth {depth}...")
        data_payload = {
            "collections": [f"crawl.{analysis}"],
            "query": {
                "dimensions": [],
                "metrics": [{"function": "sum", "args": [f"crawl.{analysis}.outlinks_internal.nb.total"]}],
                "filters": {"field": f"crawl.{analysis}.depth", "predicate": "lte", "value": depth},
            },
        }
        response = requests.post(f"https://api.botify.com/v1/projects/{org}/{project}/query", headers=headers, json=data_payload)
        data = response.json()
        edges = data['results'][0]['metrics'][0]
        if edges > 1000000 or edges == previous_edges:
            chosen_depth = depth - 1
            break
        previous_edges = edges

    update_status(f"Chosen depth: {chosen_depth}")

    # Prepare the export job
    data_payload = {
        "job_type": "export",
        "payload": {
            "username": org,
            "project": project,
            "connector": "direct_download",
            "formatter": "csv",
            "export_size": 1000000,
            "query": {
                "collections": [f"crawl.{analysis}"],
                "query": {
                    "dimensions": [
                        "url",
                        f"crawl.{analysis}.outlinks_internal.graph.url",
                    ],
                    "metrics": [],
                    "filters": {"field": f"crawl.{analysis}.depth", "predicate": "lte", "value": chosen_depth},
                },
            },
        },
    }
    response = requests.post("https://api.botify.com/v1/jobs", headers=headers, json=data_payload)
    export_job_details = response.json()
    job_url = f"https://api.botify.com{export_job_details.get('job_url')}"

    # Polling for job completion
    for _ in range(300):
        response = requests.get(job_url, headers=headers)
        job_status_details = response.json()
        if job_status_details['job_status'] == 'DONE':
            download_url = job_status_details['results']['download_url']
            # Download the file
            save_as_filename = f"downloads/{org}_{project}_{analysis}_linkgraph_depth-{chosen_depth}.csv"
            download_file(download_url, save_as_filename)
            update_status("Link graph generated successfully.")
            break
        elif job_status_details['job_status'] == 'FAILED':
            update_status("Export job failed.")
            break
        time.sleep(3)
    else:
        update_status("Unable to complete download attempts successfully.")

Status Update Function Using WebSockets:

def update_status(message: str):
    # Send the status message to connected WebSocket clients
    for user in users.values():
        asyncio.run_coroutine_threadsafe(
            user(Div(message, id='status')),
            asyncio.get_event_loop()
        )

WebSocket Setup:

# WebSocket users
users = {}

async def on_conn(ws, send):
    users[str(id(ws))] = send

def on_disconn(ws):
    users.pop(str(id(ws)), None)

@app.ws('/ws', conn=on_conn, disconn=on_disconn)
async def ws(msg: str):
    pass  # Handle incoming messages if necessary

Update the Client-Side Code to Handle WebSocket Messages:

Include a script in the main page to establish a WebSocket connection:

Script("""
    var ws = new WebSocket('ws://' + window.location.host + '/ws');
    ws.onmessage = function(event) {
        document.getElementById('status').innerHTML = event.data;
    };
""")

Note: In this setup, the update_status function sends messages to all connected WebSocket clients. Ensure proper synchronization and thread safety when interacting with the event loop.

6. Adapt File Management

In server.py:

• Serves generated CSV files via routes like /download/{filename}.
• Handles file downloads securely.

In pipulate.py:

• Uses @rt decorator to define routes.
• Handles file serving using FileResponse.

So in botifython.py:

• Define routes to serve generated files.
• Ensure files are served securely and safely.

Code Example:

File Download Route:

from starlette.responses import FileResponse, PlainTextResponse

@rt('/download/{filename}')
def download_file(filename: str):
    import os
    from pathlib import Path
    file_path = Path('downloads') / os.path.basename(filename)
    if file_path.exists():
        return FileResponse(str(file_path), filename=file_path.name)
    else:
        return PlainTextResponse("File not found.", status_code=404)

Ensure Filename Safety:

• Use os.path.basename to prevent directory traversal attacks.
• Only allow files from the downloads directory to be served.

7. Integrate Ollama AI Responses

In server.py:

• Uses the ollama_prompt function to get AI-generated responses.
• Interacts with the Ollama AI server.

In pipulate.py:

• Implements chat_with_ollama function to interact with the Ollama AI server.
• Uses this for chat functionality.

So in botifython.py:

• Ensure the ollama_prompt or equivalent function is included.
• Use the existing methods in pipulate.py for AI interaction.
• Integrate AI responses where appropriate.

Code Example:

Define the AI Interaction Function:

def chat_with_ollama(model: str, messages: list) -> str:
    url = "http://localhost:11434/api/chat"
    payload = {
        "model": model,
        "messages": messages,
        "stream": False,
    }
    headers = {"Content-Type": "application/json"}

    try:
        response = requests.post(url, data=json.dumps(payload), headers=headers)
        response.raise_for_status()
        return response.json()['message']['content']
    except requests.exceptions.RequestException as e:
        logger.error(f"Error communicating with Ollama: {e}")
        return "I'm having trouble processing that request right now."

Use the AI Function in Responses:

For example, when the user logs in or sets a project, you can generate an AI response:

@rt('/set_token', methods=['POST'])
async def set_token(botify_token: str):
    db['botify_token'] = botify_token
    user_profile = get_user_profile(botify_token)
    if user_profile:
        username = user_profile.get('data', {}).get('username', 'User')
        db['username'] = username
        
        # Generate an AI welcome message
        ai_response = chat_with_ollama('llama3.2', [
            {"role": "user", "content": f"Welcome {username} to Botifython!"}
        ])
        
        return Div(
            P(f"Welcome, {username}!"),
            P(ai_response),
            Script("setTimeout(() => window.location.href = '/', 2000);")
        )
    else:
        return Div(P("Invalid Botify Token. Please try again."), Script("setTimeout(() => window.location.href = '/', 2000);"))

8. Update the User Interface

In server.py:

• Uses HTML templates and HTMX for dynamic content.
• Provides forms and buttons for user interactions.

In pipulate.py:

• Uses FastHTML elements to build the UI.
• Defines navigation menus and content areas.

So in botifython.py:

• Recreate UI components using FastHTML’s idiomatic HTML generation.
• Integrate the Botify-specific functionality into the existing layout.
• Use the menu and navigation patterns from pipulate.py.

Code Example:

Update the Main Route with Enhanced UI:

@rt('/')
def index():
    botify_token = db.get('botify_token')
    if botify_token:
        username = db.get('username', 'User')
        org = db.get('org')
        project = db.get('project')
        analysis_slugs = db.get('analysis_slugs', [])
        selected_slug = db.get('selected_slug')
        
        nav = create_nav_menu()
        
        content = Div(
            nav,
            Container(
                P(f"Welcome, {username}!"),
                A("Logout", href="#", onclick="fetch('/delete_token', {method: 'POST'}).then(() => location.reload());"),
                Form(
                    Label("Enter Botify Project URL:"),
                    Input(type='text', name='project_url', value=f"https://app.botify.com/{org}/{project}/" if org and project else ''),
                    Button("Set Project", type='submit'),
                    hx_post='/update_project_url',
                    hx_target='body',
                    hx_swap='outerHTML',
                ),
                Div(
                    P(f"Current Project: {org} / {project}") if org and project else "",
                    Form(
                        Label("Select Analysis Slug:"),
                        Select(
                            *[Option(slug, selected=(slug == selected_slug)) for slug in analysis_slugs],
                            name='selected_slug'
                        ),
                        Button("Set Analysis Slug", type='submit'),
                        hx_post='/update_selected_slug',
                        hx_target='body',
                        hx_swap='outerHTML',
                    ) if analysis_slugs else "",
                ),
                Button("Generate Link Graph", onclick="startLinkGraphGeneration()") if selected_slug else "",
                Div(id='status'),
            )
        )
        
        # Include JavaScript for WebSocket and starting the link graph generation
        scripts = Script("""
            function startLinkGraphGeneration() {
                fetch('/generate_link_graph', {method: 'POST'})
                .then(response => response.text())
                .then(html => {
                    document.getElementById('status').innerHTML = html;
                });
            }
            
            var ws = new WebSocket('ws://' + window.location.host + '/ws');
            ws.onmessage = function(event) {
                document.getElementById('status').innerHTML = event.data;
            };
        """)
        
        return Titled("Botifython", content, scripts)
    else:
        # User needs to enter token
        return Titled(
            "Botifython",
            Div(
                Form(
                    Label("Enter your Botify Token:"),
                    Input(type='password', name='botify_token'),
                    Button("Submit", type='submit'),
                    hx_post='/set_token',
                    hx_target='body',
                    hx_swap='outerHTML',
                )
            )
        )

Create Navigation Menu Function:

def create_nav_menu():
    # Create navigation menu similar to pipulate.py
    nav_items = []
    nav_items.append(A("Home", href="/"))
    if db.get('botify_token'):
        nav_items.append(A("Projects", href="#", onclick="fetch('/projects').then(response => response.text()).then(html => { document.getElementById('content').innerHTML = html; });"))
        nav_items.append(A("Analysis", href="#", onclick="fetch('/analysis').then(response => response.text()).then(html => { document.getElementById('content').innerHTML = html; });"))
    nav = Nav(*nav_items)
    return nav

Ensure Consistency with FastHTML Patterns:

• Use Div, Form, Input, Button, P, and other FastHTML elements to build the UI.
• Handle user interactions with appropriate hx_post, hx_get, and JavaScript functions.

9. Reduce External Dependencies

In server.py:

• Uses external libraries like dotenv, aiohttp, zmq, watchdog.

In pipulate.py:

• Minimizes dependencies, relying on standard libraries and FastHTML.

So in botifython.py:

• Remove imports and usages of unnecessary external libraries.
• Ensure that all functionality can be achieved with standard libraries and FastHTML.

Code Changes:

• Remove imports:

# Remove these imports
# import aiohttp
# import zmq.asyncio
# from dotenv import load_dotenv, set_key, unset_key
# from watchdog.events import FileSystemEventHandler
# from watchdog.observers import Observer

• Replace aiohttp with requests.
• Use threading or asyncio as appropriate for concurrency.
• Ensure that all features are supported without external dependencies.

10. Testing and Validation

• Test each component after implementation.
• Ensure that the Botify API interactions work correctly.
• Verify that the token is stored and retrieved properly.
• Test the link graph generation process.
• Check that WebSocket communications are functioning and updates are received by the client.
• Ensure file downloads work and files are served securely.
• Validate that the AI responses are generated and displayed as expected.
• Perform user acceptance testing to ensure the UI is intuitive and responsive.

Final Notes:

• Throughout the integration, make sure to handle exceptions and errors gracefully.
• Keep the code modular to facilitate maintenance and future enhancements.
• Document the code with comments to explain the purpose and functionality of each section.
• Use logging to track the application’s behavior and to aid in debugging.
• Ensure that any sensitive information (like API tokens) is handled securely and not exposed.

By following these detailed steps and code examples, you can successfully integrate the functionality from server.py into botifython.py, adhering to the FastHTML methodology and minimizing external dependencies. The new application will maintain the essential features of server.py while benefiting from the streamlined structure and patterns established in pipulate.py.

[pasted in article up to this pont]

…to which it responds:

Sure! Let’s dive even deeper into the architectural aspects and nuances of botifython.py. I want to keep exploring every corner of how this refactoring effort can pan out, and possibly even go further than what you originally described. I’m going to structure this response with a mix of conceptual overviews and granular instructions, while peppering it with design ideas and future-proofing suggestions. Here’s an evolving thought process around this integration:

Architectural Considerations

1. Unification of Logic and Interface Layers

One key improvement I foresee is ensuring that the logic layer (e.g., handling Botify API interactions, generating CSV files) and the interface layer (UI updates, WebSocket communications) are well-separated yet communicate seamlessly. This is crucial when moving from server.py’s initial architecture to the more structured and organized pipulate.py setup.

This separation can be accomplished by creating separate modules for handling API interactions (botify_api.py), managing WebSocket communication (ws_handlers.py), and processing data (data_processor.py). Each of these modules should provide well-defined functions that botifython.py can call. This modular approach will help keep botifython.py lean and focused on routing, rendering, and integrating these modules.

Action Steps:

• Create a botify_api.py file: This module should include all functions for interacting with Botify’s API, such as fetching user profiles, projects, and analysis slugs.

• Create a ws_handlers.py file: This module should define functions that handle WebSocket connections, broadcasting messages to connected clients, and managing state changes over WebSockets.

• Create a data_processor.py file: This module should handle the core logic for data processing tasks, such as generating link graphs, exporting CSV files, and managing background processing.

By using these separate modules, you allow botifython.py to focus solely on the orchestration of these components, keeping it cleaner and more maintainable.

2. Persistence and State Management

When we look at the way server.py manages state—such as the Botify token or the selected analysis slug—it tends to mix concerns between local file storage, in-memory data, and environmental configurations. In pipulate.py, DictLikeDB provides a consistent way to manage state. The next step is to extend this to handle more complex, structured state data, perhaps with a small StateManager class that can abstract over DictLikeDB.

Action Steps:

• Create a StateManager class:

    class StateManager:
        def __init__(self, db: DictLikeDB):
            self.db = db
  
        def get_user_profile(self):
            return self.db.get('user_profile', {})
  
        def set_user_profile(self, profile: dict):
            self.db['user_profile'] = profile
  
        def get_project_details(self):
            return {
                'org': self.db.get('org', ''),
                'project': self.db.get('project', ''),
                'selected_slug': self.db.get('selected_slug', '')
            }
  
        def set_project_details(self, org: str, project: str, selected_slug: str = ''):
            self.db['org'] = org
            self.db['project'] = project
            self.db['selected_slug'] = selected_slug
  

  With a StateManager, botifython.py can use this abstraction to access and modify state without directly interacting with DictLikeDB.

3. Error Handling and Messaging

One thing to improve further is error messaging. In server.py, errors related to API interactions, token validation, and file processing can be communicated to the user in a more meaningful way through botifython.py. Introducing a MessageBroker class to manage error, warning, and information messages would be a great addition.

Action Steps:

• Create a MessageBroker class:

    class MessageBroker:
        def __init__(self, ws_clients: dict):
            self.ws_clients = ws_clients
  
        async def broadcast(self, message: str):
            for client_id, send_func in self.ws_clients.items():
                await send_func(
                    Div(
                        P(message),
                        cls='info-message'
                    )
                )
  
        async def error(self, message: str):
            for client_id, send_func in self.ws_clients.items():
                await send_func(
                    Div(
                        P(f"Error: {message}"),
                        cls='error-message'
                    )
                )
  

• By using MessageBroker, you can centralize how you send feedback to the user, whether through WebSocket, HTML updates, or logs.

4. WebSocket and Long-Running Tasks

One of the key advantages of WebSockets over ZMQ or SSE is that WebSocket connections are bidirectional, allowing the server to push updates to the client in real-time. In botifython.py, we can exploit this to provide a richer experience.

This can be taken a step further by using background tasks with asyncio.create_task() in combination with await to let the server continue processing requests while sending periodic updates over WebSocket.

Action Steps:

• Enhance WebSocket Communication:

  • Use a background worker queue to manage long-running tasks. Each task can post updates to a shared StatusQueue.

  • Create a WebSocketUpdater that listens to the StatusQueue and sends updates over WebSocket connections.

    class WebSocketUpdater:
        def __init__(self, status_queue: asyncio.Queue, ws_clients: dict):
            self.status_queue = status_queue
            self.ws_clients = ws_clients
    
        async def start(self):
            while True:
                status_message = await self.status_queue.get()
                for client_id, send_func in self.ws_clients.items():
                    await send_func(
                        Div(
                            P(status_message),
                            cls='status-update'
                        )
                    )
    

    By creating a queue-based updater, you can decouple the status reporting from the main application logic, making it easier to test and extend.

5. Granular Logging and Debugging

For a project like botifython.py, having granular logs can make debugging a lot easier. Consider using structlog or a similar library that allows for structured logging, where each log entry can be enhanced with context like request ID, user ID, and the module generating the log.

Action Steps:

• Set Up Structured Logging:

    import structlog
  
    logger = structlog.get_logger()
  
    logger.info("Botify API Token set", token=db.get('botify_token'))
    logger.warning("Token missing in request", user=db.get('username'))
  

With structured logging, you’ll get a clearer picture of what’s happening in your application, which is especially helpful when debugging asynchronous code or tracking down performance bottlenecks.

6. Expanding on AI Integration

The existing chat_with_ollama() function can be further expanded to support interactive Q&A with the user based on their current state. For example, when a user sets a project, the AI can suggest additional steps they can take, or provide insights based on the project’s data.

Action Steps:

• Extend AI Capabilities:

  • Modify the AI interaction function to take context parameters:

      def chat_with_ollama(model: str, messages: list, context: dict = None) -> str:
          if context:
              messages.append({"role": "system", "content": f"Context: {json.dumps(context)}"})
          # Existing code for calling the API...
    

  • Enhance AI responses by adding state-related context, such as the selected project, user’s current actions, and available analysis slugs.

7. Future-Proofing with Plugins

While the current version of botifython.py is designed to be a single-file solution, consider evolving it to a plugin-based architecture where new functionality (e.g., additional data visualizations, integration with other APIs) can be added as separate modules. This can be achieved using a simple PluginManager class that dynamically loads and registers plugins based on configuration or user input.

These are just a few of the ways to think about the structure, implementation, and enhancement of botifython.py. There’s a lot more that can be explored, such as caching strategies, internationalization support, and integration with third-party analytics. This project has the potential to grow into a versatile tool for SEO professionals, and each step taken to refine its architecture and implementation will pay off in terms of maintainability, scalability, and user satisfaction.

Let’s keep going as long as needed and delve even further into each of these areas or explore other topics you’d like to discuss! 😊

Me: This is all really wonderful feedback, and I will try to internalize it all while carrying out the port. I want you to also know since you have all this context on the project that would be a shame to waste, I figure why not loop you into some wacky stuff. Because an LLM can respond with code or data, that data can be parsed out and unstringified or serialized by Python and data populated or functions executed. That means if you ask an LLM for instructions to insert a Todo item, it would respond with the JSON, MicroDataAPI instructions, or whatever we instruct it to express it as, and it can be parsed out and executed. The LLM could also receive the next prompt automatically, carrying the data that was received back from when that code is executed. In this way, we can give that LLM the ability to write code for execution and interaction with the apps, adding items to the Todo list and such upon request. The functions it can execute might be limited to what the endpoints in the program are capable of receiving, but such a system can be expanded.

4o: That sounds like an exciting direction! Integrating an LLM as an active participant in executing and interacting with the app opens up many possibilities. It could truly blur the line between a static assistant and a dynamic collaborator.

Initial Thoughts on the System Design:

1. Instruction Parsing and Execution:
   • You can define a set of permissible instructions or commands that the LLM can generate. These could be things like:
     • {"action": "add_todo", "title": "New Task", "done": false}
     • {"action": "update_project", "project_url": "https://app.botify.com/new_project"}
   • Upon receiving these commands, the app can parse the JSON, validate the content, and then execute the corresponding function.
2. Creating a Secure Execution Layer:
   • Set up a secure execution layer that controls which instructions are executable.
   • Maintain a whitelist or registry of commands that map to specific application functions.
   • This registry could ensure that only safe and known actions are performed, preventing potential misuse or harmful operations.
3. Response Feedback Loop:
   • Once a command is executed, the response (e.g., success message, error, or even new data) can be returned to the LLM.
   • The LLM could then analyze the response and decide what to do next. For example, it could update its internal state or decide to perform a new action based on the result.
4. Creating a Meta-Language or DSL (Domain-Specific Language):
   • You could define a small, expressive DSL for interacting with the app. This would be the “language” the LLM uses to communicate with the app.
   • Example DSL commands:
     • AddTodo {title: "Complete project", done: false}
     • SelectProject {url: "https://app.botify.com/my_project"}
     • GenerateLinkGraph {depth: 3}
   • The application could translate these DSL commands into function calls or API requests internally.
5. Expanding the Interaction Scope:
   • You could build out this system incrementally. Start with simple Todo list interactions and then expand it to more complex tasks like managing projects, analyzing data, or even modifying application settings.
   • The LLM could evolve into a form of application agent that learns new commands as they are added to the system.
6. Self-Refinement and Learning:
   • As the LLM interacts with the application, it could build up a “memory” or context around how best to interact, respond to common errors, or streamline workflows.
   • This could be facilitated by a feedback mechanism that tracks success, errors, and changes in state.
7. Examples and Potential Use Cases:
   • A simple example would be adding a new Todo item:
     • User Query: “Can you add a task to complete the refactoring work by tomorrow?”
     • LLM Command Generation:

       {
           "action": "add_todo",
           "title": "Complete refactoring work by tomorrow",
           "done": false
       }
       

     • Application Execution and Response:
       • The app executes add_todo and returns:

         {
           "status": "success",
           "message": "Todo item added successfully.",
           "todo_id": 1234
         }
         

     • LLM Analysis and Next Step: The LLM could acknowledge the success or proceed to ask if the user wants to add a due date or other details.
8. User Control and Oversight:
   • Implement user control mechanisms where a user can review, approve, or reject commands before execution. This could help prevent undesired actions.
   • You could also have a debugging mode where the LLM shows its generated command before executing, allowing the user to confirm or modify it.
9. Potential Challenges:
   • Balancing the flexibility of the LLM’s command generation with the need to maintain control and predictability.
   • Defining a robust error-handling strategy to manage unexpected commands, malformed data, or conflicts in app state.
   • Maintaining performance and responsiveness, especially if the LLM’s decisions lead to a chain of interactions or long-running tasks.

Technical Implementation Ideas

To give you a concrete starting point, here’s how you could start building the instruction parsing and execution module:

# Command Registry: Maps action names to functions
command_registry = {
    "add_todo": lambda data: todos.insert({"title": data["title"], "done": data.get("done", False)}),
    "update_project": lambda data: db.__setitem__('project_url', data["project_url"]),
}

def execute_command(command_json):
    """Parses and executes a command from JSON input."""
    try:
        command = json.loads(command_json)
        action = command.get("action")
        if action in command_registry:
            result = command_registry[action](command)
            return {"status": "success", "result": result}
        else:
            return {"status": "error", "message": f"Unknown action: {action}"}
    except Exception as e:
        return {"status": "error", "message": str(e)}

# Example usage
response = execute_command('{"action": "add_todo", "title": "Complete project", "done": false}')
print(response)  # Outputs: {"status": "success", "result": <inserted_todo_object>}

Next Steps

If you’d like, we can start implementing some core aspects of this system, such as:

1. Defining the Command Registry:
   • Implement a command registry that maps action strings to functions.
   • Establish error handling and validation rules for each command.
2. Creating a Feedback Loop:
   • Develop a feedback loop where the LLM receives execution results and can decide what to do next.
   • Implement a message broker or intermediary to handle the communication between the app and LLM.
3. Integrating with the UI:
   • Develop UI hooks that allow the LLM to modify the app’s state or add/remove items based on user queries.
4. Expanding Commands and Functionality:
   • Gradually expand the list of supported commands, starting with the Todo list and moving into more complex operations.

If this sounds like a plan you’d like to pursue, we can break it down further or start coding specific pieces. The potential is immense, and this could turn into a highly interactive, intelligent agent that extends well beyond typical application interactions!

Me: I’m taking notes. It makes a lot of sense. I think as my next step is incorporating RAG features. I think I can get FAISS running right here local on this machine. I’m using Nix Flakes, so I can reproduce infrastructure in its entirety with a simple text file. So, I could probably make the existence of a vector database as presumed available to this system as I do an external ollama server. That way as the app gets used more, we can upload and digest documents that the local LLM can query. It’s not going to be a big built-out system, but a readily installed, easily instantiated, multiple-instance friendly system. Anything the user does in chat and the user interface can go into the vector database. Any document produced by the system, like downloads from other systems or uploads by the user can be digested. It will probably be common to save files onto the local storage and produce embeddings and keep file paths, so the system can tell you about all the documents of which its aware and refer to long past chats. The LLM will be encouraged to search and add contents from the vector database when answering queries. Give me instructions on moving forward.

4o: Implementing Retrieval-Augmented Generation (RAG) with Local FAISS Database

Overview

To move forward with integrating RAG features, the plan involves setting up a local FAISS-based vector database that can ingest various types of data, such as chat interactions, user-uploaded documents, and system-generated files. This will enable the LLM to access a rich context of historical interactions and document content, ultimately enhancing its responses by pulling relevant information as needed.

Key Objectives

1. Set Up Local FAISS with Nix Flakes:
   • Create a reproducible environment for FAISS installation using Nix Flakes.
   • Configure the FAISS vector database for efficient indexing and querying.
2. Create a Data Ingestion Pipeline:
   • Implement mechanisms to ingest chat interactions, documents, and other data into the vector database.
   • Generate embeddings for text content using a suitable model (e.g., sentence-transformers or openai-embedding).
3. Implement a Document Query Interface:
   • Design a query interface for the LLM to access and retrieve relevant data from the FAISS database.
   • Provide the LLM with endpoints to request embeddings and retrieve documents or chat histories.
4. Integrate with the Local LLM:
   • Extend the LLM’s capabilities to include retrieval of information from the FAISS database.
   • Implement a mechanism for the LLM to leverage the retrieved context during response generation.
5. Ensure System Robustness and Scalability:
   • Build a monitoring and logging system to track data ingestion and retrieval operations.
   • Establish a schema for organizing and retrieving vectors, ensuring the system scales efficiently as more data is added.

Step-by-Step Implementation Instructions

1. Set Up Local FAISS with Nix Flakes

1. Create a Nix Flake Configuration: Create or modify the Nix Flake configuration file (flake.nix) to include FAISS and other necessary dependencies.

   {
     description = "FAISS Setup for Local Vector Database";
        
     inputs = {
       nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
     };
        
     outputs = { self, nixpkgs }:
       let
         system = "x86_64-linux";
         pkgs = import nixpkgs { inherit system; };
       in
       {
         packages.${system}.faissEnv = pkgs.mkShell {
           buildInputs = [
             pkgs.python3
             pkgs.faiss
             pkgs.pip
           ];
           shellHook = ''
             pip install faiss-cpu
             echo "FAISS environment setup complete."
           '';
         };
       };
   }
   

2. Activate the FAISS Environment: Activate the environment using nix develop:

   nix develop .#faissEnv
   

3. Install Additional Python Libraries: Install any additional libraries needed for FAISS integration, such as numpy and sentence-transformers:

   pip install numpy sentence-transformers
   

2. Create a Data Ingestion Pipeline

1. Define a Function to Generate Embeddings: Create a Python function to generate embeddings for text content using a transformer model like sentence-transformers.

   from sentence_transformers import SentenceTransformer
   import faiss
   import numpy as np
   
   # Load a pre-trained sentence transformer model
   model = SentenceTransformer('paraphrase-MiniLM-L6-v2')
   
   def generate_embeddings(texts):
       """Generate embeddings for a list of texts."""
       return model.encode(texts, convert_to_numpy=True)
   

2. Implement the FAISS Indexing Logic: Create a FAISS index to store and query embeddings.

   def create_faiss_index(dimension):
       """Create a FAISS index with the specified dimensionality."""
       index = faiss.IndexFlatL2(dimension)  # L2 distance index
       return index
   
   # Create a new FAISS index based on the embedding dimension
   embedding_dimension = 384  # Dimension of the 'paraphrase-MiniLM-L6-v2' model
   faiss_index = create_faiss_index(embedding_dimension)
   

3. Ingest Data into the FAISS Database: Create a function to add new vectors (e.g., chat logs or document embeddings) to the FAISS index.

   def add_to_faiss_index(index, texts):
       """Add text embeddings to the FAISS index."""
       embeddings = generate_embeddings(texts)
       index.add(embeddings)
   
   # Example usage: Adding chat logs to the FAISS index
   chat_logs = ["This is a sample chat log.", "Another interaction."]
   add_to_faiss_index(faiss_index, chat_logs)
   

4. Save and Load the FAISS Index: Implement a mechanism to persist and load the FAISS index for future use.

   def save_faiss_index(index, path):
       """Save the FAISS index to a file."""
       faiss.write_index(index, path)
   
   def load_faiss_index(path):
       """Load a FAISS index from a file."""
       return faiss.read_index(path)
   
   # Save the current index
   save_faiss_index(faiss_index, 'faiss_index.bin')
   
   # Load the index later
   loaded_index = load_faiss_index('faiss_index.bin')
   

3. Implement a Document Query Interface

1. Create a Function to Perform Vector Search: Implement a search function that finds the closest vectors in the FAISS index.

   def search_faiss_index(index, query, top_k=5):
       """Search the FAISS index for the top_k closest embeddings."""
       query_embedding = generate_embeddings([query])
       distances, indices = index.search(query_embedding, top_k)
       return distances, indices
   
   # Example search
   query = "Find interactions related to embeddings."
   distances, results = search_faiss_index(loaded_index, query)
   print(f"Top results: {results}")
   

2. Integrate with the LLM: Extend the LLM’s capabilities to include retrieval from the FAISS database. Create an endpoint that accepts LLM requests and provides responses based on vector searches.

   @rt('/query_faiss')
   def query_faiss_endpoint(request):
       query_text = request.query_params.get('q')
       distances, results = search_faiss_index(faiss_index, query_text)
       return {'distances': distances.tolist(), 'results': results.tolist()}
   

3. Enable the LLM to Retrieve and Use Context: Modify the LLM’s response generation to include relevant context from the FAISS database when responding to queries.

   def augment_with_context(prompt, context):
       """Combine prompt with context information for enhanced response generation."""
       augmented_prompt = f"{context}\n\n{prompt}"
       return augmented_prompt
   
   # Use the augmented prompt for response generation
   context = " ".join([chat_logs[i] for i in results[0]])
   augmented_response = augment_with_context("Explain embeddings.", context)
   print(augmented_response)
   

4. Integrate FAISS with Local LLM

1. Create a Background Process for Ingestion and Query: Set up background processes or endpoints in botifython.py that handle data ingestion and query operations.

2. Configure the LLM to Use Retrieved Context: Ensure the LLM fetches relevant context from FAISS and uses it when generating responses, providing more informed and coherent answers.

3. Log and Track LLM Interactions: Record each LLM interaction and the context it used, which can later be indexed into FAISS for future queries.

5. Enhance System Robustness

1. Implement Logging and Monitoring: Add logging for FAISS indexing, retrieval operations, and LLM interactions to track the system’s state and performance.

2. Establish a Schema for Organizing Data: Design a schema that categorizes embeddings based on their source (e.g., chat log, document, system file) and context for efficient retrieval.

3. Test Scalability and Efficiency: Run benchmarks to ensure the system performs efficiently as more data is added. Optimize the FAISS index if necessary.

Final Thoughts

By incorporating FAISS and building a local vector database, you are setting the foundation for a highly responsive and contextually aware system. The integration will allow your LLM to access a wealth of information stored locally, improving its ability to answer queries, refer to past interactions, and interact with documents uploaded by the user.

Let me know if you want further guidance or help with any specific part of this integration!

Me: Work it into my flake.nix…

4o: Here’s how to integrate FAISS and RAG features into your flake.nix file and ensure everything is set up correctly:

Step 1: Update the flake.nix File

We need to modify flake.nix to include FAISS, the sentence-transformers library for generating embeddings, and other necessary dependencies. I’ll also update the development shell to include a few custom scripts for FAISS setup and interactions.

{
  description = "A flake that reports the OS using separate scripts with optional CUDA support and unfree packages allowed.";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

        # Choose the appropriate development shell based on the OS
        devShell = if isLinux then linuxDevShell else darwinDevShell;
      });
}

Step 2: Update requirements.txt

Make sure your requirements.txt includes the necessary packages for FAISS and embedding generation:

numpy
pandas
requests
jupyterlab
python-fasthtml
faiss-cpu
sentence-transformers
scipy
sentencepiece

Step 3: Testing the Setup

1. Activate the Development Shell: From the root directory of your project, activate the Nix shell:

   nix develop .#devShell
   

2. Run the Setup Script: This will set up your environment, create the virtual environment, and prepare the FAISS index:

   setup-faiss
   

3. Interact with the FAISS Index: Run the interaction script to test adding texts to the FAISS index:

   faiss-interact
   

   This script will load the index, add a sample text, and save the updated index.

Step 4: Integration with botifython.py

1. Implement Ingestion and Query Functions in botifython.py: Create Python functions that will leverage the FAISS index for both ingestion and querying. Use the existing scripts as a base and extend their functionality within botifython.py.

   import faiss
   import numpy as np
   from sentence_transformers import SentenceTransformer
   
   # Load the FAISS index and the transformer model
   model = SentenceTransformer('paraphrase-MiniLM-L6-v2')
   index_path = 'faiss_index.bin'
   if os.path.exists(index_path):
       faiss_index = faiss.read_index(index_path)
   else:
       faiss_index = faiss.IndexFlatL2(384)  # Assuming 384-dimensional embeddings
   
   def add_text_to_index(text):
       """Generate an embedding for the text and add it to the FAISS index."""
       embedding = model.encode([text])
       faiss_index.add(np.array(embedding, dtype=np.float32))
       faiss.write_index(faiss_index, index_path)
       return f"Text '{text}' added to FAISS index."
   
   def query_faiss_index(query_text, top_k=5):
       """Query the FAISS index and return the closest matches."""
       query_embedding = model.encode([query_text])
       distances, indices = faiss_index.search(np.array(query_embedding, dtype=np.float32), top_k)
       return distances, indices
   

2. Create Endpoints in botifython.py: Define endpoints for ingestion and querying, so the LLM can interact with the FAISS index through HTTP requests.

   @rt('/add_to_index')
   async def add_to_index_endpoint(request):
       text = request.query_params.get('text', '')
       if not text:
           return PlainTextResponse("No text provided.", status_code=400)
       result = add_text_to_index(text)
       return PlainTextResponse(result)
   
   
   
   @rt('/query_index')
   async def query_index_endpoint(request):
       query_text = request.query_params.get('query', '')
       if not query_text:
           return PlainTextResponse("No query provided.", status_code=400)
       distances, indices = query_faiss_index(query_text)
       return JSONResponse({"distances": distances.tolist(), "indices": indices.tolist()})
   

3. Test the New Endpoints: Use a tool like curl or a REST client to test the new endpoints:

   curl -X POST "http://localhost:8000/add_to_index?text=This is a sample text."
   curl -X GET "http://localhost:8000/query_index?query=sample"
   

4. Integrate FAISS Queries into LLM Response Generation: Modify the LLM’s response generation logic to include relevant context retrieved from the FAISS index.

This setup should give you a solid foundation for integrating FAISS and RAG features into your application using Nix Flakes. Let me know if you need further guidance or help with any specific part of the setup!

Me: This is excellent, and exactly what I was looking for, except for the fact that any Python components except for Python itself, pip and virtualenv should actually be added to the requirements.txt, because all Python is managed from the .venv this flake establishes for Python. Take another look…

4o: Got it! Since you want to keep all Python dependencies in the requirements.txt and ensure that only Python itself, pip, and virtualenv are managed by the flake, we will remove direct references to Python packages like faiss and sentence-transformers from flake.nix.

The flake will then focus on setting up the virtual environment and ensuring the system-level dependencies are installed correctly. Here’s an updated version of your flake.nix:

Key Changes:

1. Removed Direct Python Dependencies in flake.nix: All Python-related libraries like faiss, sentence-transformers, numpy, etc., have been moved to the requirements.txt file, leaving only python311, pip, and virtualenv in flake.nix.

2. Simplified flake.nix Structure: The flake now sets up a virtual environment and installs packages using pip from the requirements.txt file as part of its initialization.

3. Instructions in requirements.txt: Make sure your requirements.txt includes all necessary Python packages, including FAISS and any other dependencies:

numpy
pandas
requests
jupyterlab
python-fasthtml
faiss-cpu
sentence-transformers
scipy
sentencepiece

Final Steps:

1. Activate the Development Shell: From the root of your project directory, activate the Nix development shell:

   nix develop .#devShell
   

2. Check and Install Python Packages: Ensure the requirements.txt is in place and correctly formatted. This flake will automatically set up the Python virtual environment and install all packages listed in requirements.txt inside the .venv.

3. Run the Setup and Scripts: Once in the shell, you can use the scripts like setup-faiss or any others you’ve created to initialize or interact with your local FAISS setup.

This flake configuration now adheres to your specified setup, where all Python dependencies are managed through requirements.txt, giving you flexibility in managing and updating the environment with standard Python tools

like pip. Let me know if there’s anything else to refine or adjust!

Deep Breath Before the Port

Okay, so we are blending 2 apps together.

Ugh, this switch to Cursor AI… it’s not like I’m giving up vim. Nobody ever really gives up vim. We learn to make due between those times when vim is our main text editor by filling it up with a fad. Today’s fad, ladies and gentlemen, is Cursor AI, and I’m getting the most of it.

I’m moving both the Pipulate flake.nix an pipulate.py file into the Botifython folder. Then I should be able to nix develop after a few precautions, such as deleting the old flake.lock and doing a nix collect-gabage command. It’s to “clear the cache” such as it were. And now I have tested that I can successfully run either app from out of that folder, with:

• python server.py
• python pipulate.py

Both confirmed. So, I make the 3rd version botifython.py based on pipulate.py and run that. Bingo! I’ve got a place to start working.
