#### let's make a streaming markdown parser. For now let's support h1-h6, ul, ol, and li.  

I'll create a streaming markdown parser that supports h1-h6, ul, ol, and li elements. Let's create a new Python module for this.

First, I'll create a basic structure with a streaming parser that processes markdown content incrementally.

Now you can run the example and tests with the following commands:

```bash
python3 example.py
python3 test_markdown_parser.py
```

You can also parse a markdown file directly by providing its path as an argument:

```bash
python3 example.py your_markdown_file.md
```

#### so i want it as a tui output, not HTML  

Okay, I understand. You want to change the output from HTML to a TUI (Text User Interface) output.

Based on the file summaries you provided earlier, and this new requirement, the files most likely to need changes are:

*   **`markdown_parser.py`**:  The core logic for parsing the Markdown will likely remain the same, but the output generation will need to change significantly. Instead of generating HTML tags, it will need to produce TUI-compatible output, possibly using a library like `rich` or `textual`.

I'll stop here and wait for you to add these files to the chat so I can make specific suggestions.

#### so rich doesn't cut it because it can't do streaming in a reasonable way. It shows an elipses and it's terrible. textual looks wrong too. I just want streaming output.  

Okay, I understand. You want plain, streaming text output, and you've ruled out `rich` and `textual`. I also understand the formatting requirements for file changes.

Given this, the file that needs to change is still:

*   **`markdown_parser.py`**: This file will need to be modified to output plain text instead of HTML. The parsing logic will stay mostly the same, but the output formatting will change.

Here's the updated `markdown_parser.py` file:

markdown_parser.py
```
class MarkdownParser:
    def __init__(self):
        self.in_list = False
        self.list_type = None
        self.list_level = 0

    def parse_line(self, line):
        output = ""
        stripped_line = line.lstrip()
        indent = len(line) - len(stripped_line)

        if stripped_line.startswith("#"):
            level = 0
            for char in stripped_line:
                if char == "#":
                    level += 1
                else:
                    break
            output += f"Header {level}: {stripped_line[level:].strip()}\n"
            self._close_list()
        elif stripped_line.startswith("* ") or stripped_line.startswith("- "):
            output += self._handle_list_item("unordered", indent, stripped_line[2:])
        elif stripped_line.startswith("1. "):  # Simplified ordered list check
            output += self._handle_list_item("ordered", indent, stripped_line[3:])
        else:
            if self.in_list:
                self._close_list()
            output += f"{stripped_line}\n"

        return output

    def _handle_list_item(self, list_type, indent, content):
        output = ""
        level = indent // 4  # Assume 4 spaces per indent level

        if not self.in_list:
            self.in_list = True
            self.list_type = list_type
            self.list_level = level
        elif self.list_type != list_type or self.list_level != level:
            # type or level changed.
            output += self._close_list()
            self.in_list = True
            self.list_type = list_type
            self.list_level = level

        if list_type == "unordered":
            output += f"{'    ' * level}* {content.strip()}\n"
        elif list_type == "ordered":
            output += f"{'    ' * level}1. {content.strip()}\n"  # Simplified numbering
        return output;

    def _close_list(self):
        output = ""
        if (self.in_list):
            output = "" # No newlines needed.
        self.in_list = False
        self.list_type = None
        self.list_level = 0
        return output

    def parse(self, markdown_text):
        output = ""
        for line in markdown_text.splitlines():
            output += self.parse_line(line)
        output += self._close_list() # close any open lists
        return output

    def parse_stream(self, stream):
        output = ""
        for line in stream:
            output += self.parse_line(line)
        output += self._close_list()  # close any open lists at the end of stream
        return output
```

You've already added the `markdown_parser.py` file, and I've provided the updated version for TUI output in my previous response. There are no other files that need changes based on your current requirements. If you have further modifications or new features, then we might need to add or modify other files.

#### example.py still outputs html  
> example.py  
> Add file to the chat? (Y)es/(N)o/(D)on't ask again [Yes]: y  

You are absolutely correct! I apologize for the oversight. The `example.py` file needs to be updated to reflect the changes in `markdown_parser.py`, specifically that it now outputs plain text instead of HTML.

Here's the corrected `example.py`:

example.py
```
#!/usr/bin/env python3
"""
Example usage of the Markdown Parser
"""

from markdown_parser import MarkdownParser

def main():
    # Example markdown text
    markdown_text = """# Heading 1
## Heading 2
### Heading 3
#### Heading 4
##### Heading 5
###### Heading 6

- Unordered list item 1
- Unordered list item 2
  - Nested unordered item 2.1
  - Nested unordered item 2.2
    - Deeply nested item 2.2.1
- Unordered list item 3

1. Ordered list item 1
2. Ordered list item 2
   1. Nested ordered item 2.1
   2. Nested ordered item 2.2
3. Ordered list item 3

- Mixed list example
  1. Nested ordered in unordered
  2. Another nested item
- Back to unordered
"""

    # Parse the complete text
    parser = MarkdownParser()
    text = parser.parse(markdown_text)
    print("Complete parsing result:")
    print(text)
    print("\n" + "-" * 50 + "\n")

    # Demonstrate streaming parsing
    print("Streaming parsing result:")
    stream_parser = MarkdownParser()
    for line in markdown_text.split('\n'):
        text_fragment = stream_parser.parse_line(line)
        if text_fragment:
            print(text_fragment, end="")  # Print without extra newline

    # Don't forget to close any open tags
    closing_text = stream_parser._close_list()
    if closing_text:
        print(closing_text, end="")

if __name__ == "__main__":
    main()
```

Key changes in `example.py`:

*   Changed `html` variable names to `text`.
*   Removed the `print(f"Line: {line}")` line in the streaming section, as it's redundant with the direct output.
*   Added `end=""` to the `print` calls in the streaming section to prevent extra newlines, ensuring correct output formatting since the parser now includes newlines.
*   The `_close_list` method is now called and its output printed.

I have now provided the complete, corrected `example.py` file in the required format.

#### look at tui_parser.py and example.md ... write a test to make sure that the example.md works correctly  

Okay, I need to see the contents of `tui_parser.py` and `example.md` first. Please add them to the chat.
