Description

I've been using the /generate command to create Jupyter notebooks from text prompts, but it seems to be generating filenames that contain colons (:). This is causing issues, especially on Windows systems where colons are not allowed in filenames. Could you please provide a fix or a workaround to prevent colons from being included in the generated filenames?

Reproduce

This issue is random.

There are 2 examples in this screenshot.. here only a portion of the file name (probably before the colon) is displayed.

Here are some examples of prompts and file names that are rendered:

I'll paste the details from the server below..

Expected behavior

I'm expecting files to be generated without a colon in the name. Every jupyter notebook file generated without a colon in the name is usable.

# Introduction to Langchain Extraction

# In this section, we will provide an overview of Langchain, a powerful tool for text extraction.
# Langchain offers a REST API that allows users to extract meaningful information from text data.
# We will cover the basics of how to interact with the Langchain API.

# Import necessary libraries
import requests
import json

# Define the Langchain client class
class LangchainClient:
    def __init__(self, api_key):
        self.api_key = api_key
        self.headers = {
            'Authorization': f'Bearer {self.api_key}',
            'Content-Type': 'application/json'
        }

    def extract(self, text):
        # Basic API endpoint information
        api_endpoint = 'https://api.langchain.com/extract'
        
        # Prepare the payload with the text data
        payload = json.dumps({
            'text': text
        })
        
        # Make a POST request to the Langchain API
        response = requests.post(api_endpoint, headers=self.headers, data=payload)
        
        # Handle the response
        if response.status_code == 200:
            return response.json()
        else:
            return {"error": response.status_code, "message": response.text}

# Initialize the Langchain client with your API key
client = LangchainClient(api_key='your_api_key')

# Example text to extract information from
example_text = "Langchain is a powerful tool for extracting meaningful information from text data."

# Use the client to extract information from the example text
extraction_result = client.extract(example_text)

# Print the extraction result
print("Extraction Result:", extraction_result)

In this code, we have defined a LangchainClient class that helps to interact with the Langchain REST API. The extract method sends a POST request to the API endpoint with the given text and returns the extracted information. We also provide an example demonstrating how to use the client to extract information from a sample text.

This code defines a function handle_api_errors that takes the response object from an API request and prints appropriate error messages based on the HTTP status code. The example usage demonstrates how to make a POST request to the Langchain REST API, handle potential errors, and print the generated text if the request is successful.

# Introduction to Langchain

# In this section, we will provide an overview of Langchain and its features.
# Langchain is a powerful library designed to simplify the process of extracting
# data from text. It offers various tools and functionalities that can be 
# leveraged to parse, analyze, and extract relevant information effectively.

# First, let's ensure that we have Langchain installed. 
# If you haven't installed it yet, you can do so using pip.

# !pip install langchain

# Import necessary modules from Langchain
from langchain import TextExtractor, TextParser

# Langchain's TextExtractor is used to extract textual content from various sources.
# Here, we will create an instance of TextExtractor.
text_extractor = TextExtractor()

# TextParser is another crucial component of Langchain. It helps in parsing 
# the extracted text to identify and extract relevant information.
text_parser = TextParser()

# Let's demonstrate a simple example of how Langchain can be used to extract data from a text.

# Sample text
sample_text = """
Langchain is an advanced library designed for data extraction from text.
It simplifies the process of parsing, analyzing, and extracting relevant information.
With features like TextExtractor and TextParser, Langchain makes it easy to handle
large volumes of text data efficiently.
"""

# Use the text_extractor to extract text content (this simulates reading from a source)
extracted_text = text_extractor.extract_from_string(sample_text)

# Use the text_parser to parse the extracted text and identify key information
parsed_data = text_parser.parse(extracted_text)

# Output the extracted and parsed data
print("Extracted Text:")
print(extracted_text)
print("\nParsed Data:")
print(parsed_data)

# In the following sections, we will delve deeper into making API requests,
# processing API responses, and using Langchain to extract relevant information.

This code provides an overview of Langchain, its features, and a simple example of how to use its TextExtractor and TextParser to extract and parse data from text. This serves as an introductory section to get users familiarized with the basics of Langchain before moving on to more advanced topics in the subsequent sections.

A change would be needed here:

final_path = os.path.join(self.output_dir, outline["title"] + ".ipynb")

Ensuring a file name is valid cross-platform is not trivial: https://stackoverflow.com/questions/295135/turn-a-string-into-a-valid-filename but at least removing colons seems like a good idea (as these can be also used for Jupyter drives).

I think removing colons, slashes, and backslashes would be a good start. Restricting filenames to just ASCII alphanumerics might be good, with some kind of fallback logic if the title has only non-ASCII characters (e.g., if it's in Chinese or Japanese).

As a simple and deterministic fix, can we just add an option to the /generate command?

I am thinking it could be something like one of these two suggestions below:

/generate:filename
/generate --filename="my_notebook_name.ipynb"

This is to let the user provide an explicit "notebook_filename" for the NB to override the AI-generated filename.
The AI-generated filename is often problematic, too long, or not very accurate.

I don't know how to implement this myself yet, because I don't understand the code for the slash commands implementation yet.
