This diff adds a check before the main function to see if Chromium can be launched. If an exception occurs, it assumes Chromium is not installed and proceeds to install it using Playwright's command-line interface.

```
This diff removes the asynchronous code and replaces it with the synchronous version provided by Playwright's `sync_api`. The `async` and `await` keywords are removed, and the `async_playwright` context manager is replaced with `sync_playwright`. The script should now run synchronously.
# Aider chat conversation:
USER: write a playwright script to fetch the text from a url supplied on the cmd line
ASSISTANT: To create a Playwright script that fetches text from a URL supplied on the command line, I will write the necessary code in the `playw.py` file. The script will use Playwright's Python package to launch a browser, navigate to the provided URL, and print the text content of the page to the console.
Here is the diff for the new `playw.py` file:
```diff
--- /dev/null

```
This script will require the Playwright package to be installed. You can install it using `pip install playwright` and then run `playwright install` to install the necessary browser binaries. To run the script, use the command `python playw.py <URL>`, replacing `<URL>` with the actual URL you want to fetch text from.

ASSISTANT: It seems there might be a misunderstanding. You've indicated that you've added the `requirements.in` file, but you haven't specified any changes that need to be made to it or any other files. If you need any modifications or have any specific requests regarding the `requirements.in` or any other file, please let me know, and I'll be happy to assist you with the necessary changes.

```
This change adds `chromedriver-autoinstaller` to the `requirements.in` file, which is used to generate the `requirements.txt` file with `pip-compile`. After adding this line, you would run `pip-compile requirements.in` to update the `requirements.txt` file accordingly.
# Aider chat conversation:
USER: does the user need to install anything beyond the pip requirements to have selenium drive chrome?
ASSISTANT: To have Selenium drive Chrome, the user needs to have the Chrome browser installed on their system and also the ChromeDriver executable, which allows Selenium to interface with Chrome. The ChromeDriver version must be compatible with the version of Chrome installed on the system.
The `requirements.txt` file already includes `selenium`, but it does not include `chromedriver-autoinstaller`, which can automatically download and install the correct version of ChromeDriver for the user's version of Chrome. To facilitate this, we can add `chromedriver-autoinstaller` to the `requirements.txt` file.
Here is the diff to add `chromedriver-autoinstaller` to the `requirements.txt`:
```diff
--- requirements.txt
+++ requirements.txt
@@ ... @@
+selenium==4.17.2

By adding `chromedriver-autoinstaller`, the user can ensure that the correct version of ChromeDriver is installed and updated as needed, without manual intervention.

# Aider chat conversation:
USER: make sire self.live.stop() is called no matter how the object gets destroyed
ASSISTANT: To ensure that `self.live.stop()` is called no matter how the object gets destroyed, we can use Python's built-in `__del__` method. This method is called when an object is about to be destroyed. We can override this method in our `MarkdownStream` class to stop the `Live` instance.
Here are the steps to make this change:
1. Add a `__del__` method to the `MarkdownStream` class that calls `self.live.stop()`.
