Great start! Let's begin by clarifying the core functionality.

**Question 1:**

Should the exported URL be permanent (i.e., saved on a server) or purely
client-side (i.e., encoded in the URL without any backend storage)?

This will determine whether we need a backend service or if we can rely
entirely on frontend logic.

Got it! That simplifies deployment and eliminates the need for a backend.

**Question 2:**

How long should the encoded markdown be allowed to get? Base64 encoding
increases the size of the content, and long URLs might hit browser limits.
Should we set a practical character limit, or allow arbitrarily long
snippets?

That makes sense for usability and compatibility. Since base64 encoding
increases size by about **33%**, we need to account for that.

For example:

*   If we allow **1500 characters of raw markdown**, base64 will expand it to ~2000 characters.
*   If we allow **1600 characters**, it will be ~2133 characters, exceeding our limit.

We’ll need to test the exact cutoff, but we can approximate it by allowing
**around 1500 characters** of raw markdown.

**Question 3:**
When the user exceeds this limit, should we:

1.  **Prevent further typing** (hard limit).
2.  **Show a warning but allow exceeding the limit until export** (soft limit).
3.  **Truncate automatically at export** (cutoff silently).

Great, so we’ll implement a **soft limit** with a warning when the user
exceeds the 1500-character mark, but they can keep typing.

**Question 4:**
How should the warning be displayed?

*   **Inline message** below the editor (e.g., “Warning: Your snippet may be
    too long to share via URL.”)
*   **Character counter** that changes color when exceeding the limit
*   **Modal popup** that appears when trying to export an oversized snippet
*   Something else?

Perfect! We'll have a **character counter** visible at all times, and when
the user exceeds 1500 characters, an **inline warning message** will appear
below the editor.

**Question 5:**
Should the counter show:

1.  **Characters used (e.g., "1540/1500")**, making it clear they’ve exceeded the limit.
2.  **Characters remaining (e.g., "Remaining: -40")**, which becomes negative when over the limit.
3.  **Only the total count** with color change (e.g., black when under, red when over).

Got it! The counter will display **characters remaining**, turning negative
when over the limit.

**Question 6:**
Should the inline warning message always be visible when over the limit, or
only appear when the user tries to export?

Great! The warning will **always be visible** when the character count goes
negative.

**Question 7:**
Should the warning text be fixed (e.g., “Warning: Your snippet may be too
long to share via URL.”) or dynamic (e.g., “Warning: Your snippet is 40
characters over the limit.”)?

Understood! The warning will always say:
**“Warning: Your snippet may be too long to share via URL.”**

**Question 8:**
Should we allow users to manually shorten their text, or provide an automatic
“Trim to Fit” button that removes excess characters?

Got it! Users will need to manually shorten their text if it exceeds the limit.

**Question 9:**
Should we provide any formatting tools (e.g., bold, italic, equation
insertion buttons), or just a plain markdown editor with a preview?

> Great! It will be a straightforward **plain markdown editor** with a live
> preview.
>
> **Question 10:**
> How should the preview update? Should it update:
>
> 1.  **In real-time** as the user types.
> 2.  **On a specific action** (like clicking a button or losing focus on the editor).

> Excellent choice! The preview will update in **real-time**, but with a
> **2-second delay** after the user stops typing to optimize performance.
>
> **Question 11:**
> For the "Export" button, how should it be labeled? Should it simply say
> "Export," or would you prefer something more descriptive, like "Generate URL"
> or "Share Snippet"?

> Got it! The button will be labeled **"Generate URL."**
>
> **Question 12:**
> After the URL is generated, should the tool:
>
> 1.  **Automatically copy the URL to the clipboard** and display a confirmation message.
> 2.  **Display the URL in a text box** for the user to copy manually.
> 3.  **Open the generated URL in a new tab** for the user.
> 4.  **Provide both options**?

> Perfect! After generating the URL, it will be displayed in a text box with a
> **"Copy to Clipboard"** button next to it.
>
> **Question 13:**
> Should the tool include any functionality to handle potential errors (e.g.,
> if the URL fails to generate)? If so, what kind of error messages or feedback
> would you like to provide to the user?

> Understood! We’ll keep the tool lean and avoid error handling for URL generation.
>
> **Question 14:**
> How should the overall layout be structured? For example:
>
> 1.  **Editor on the left, preview on the right**
> 2.  **Editor on top, preview below**
> 3.  **Split view with tabs** for switching between editor and preview
> 4.  Something else?

> Got it! The layout will have the **editor on the left** and the **preview on
> the right.**
>
> **Question 15:**
> Would you like to include any footer or header elements, such as a title for
> the page, a logo, or links to other resources? If so, what should they
> include?

> That sounds good! Just a couple of suggestions for clarity:
>
> 1.  **Year**: Make sure the year is dynamic so it always reflects the current year.
> 2.  **Copyright Notice**: Typically includes something like "© Year DLD. All rights reserved."
>
> With those in mind, here's a quick overview of the header and footer:
>
> *   **Header**: "TEST SITE", "About this site" link, "Source" link.
> *   **Footer**: "© Current Year DLD. All rights reserved", "Report Issue" link to GitHub.
>
> **Question 16:**
> Is there any specific styling or color scheme you'd like to use for the
> editor, preview, header, and footer, or should we keep it simple and default?

> Got it! We'll keep the design **simple and default** for the editor, preview,
> header, and footer.
>
> **Question 17:**
> Finally, do you have any specific requirements for browser compatibility, or
> should we aim for the latest versions of major browsers (Chrome, Firefox,
> Safari, Edge)?

> Understood! We'll aim for compatibility with the **latest versions of major
> browsers** (Chrome, Firefox, Safari, Edge).
>

Prompts for Code Generation LLM
——————————-

### Prompt 1: Project Initialization

``Create a new directory structure for a math snippet sharing tool. Inside the
directory, create three files: `index.html`, `styles.css`, and `script.js`. Set
up a basic HTML document structure in `index.html`.``

### Prompt 2: HTML Layout Creation

``In the `index.html` file, add the following structure: - A header section
that contains the site name "TEST SITE", an "About this site" link, and a
"Source" link. - A main section with two divs: one for the editor (markdown
input) and one for the preview. - A footer section that contains "© [Current
Year] DLD. All rights reserved" and a "Report Issue" link to GitHub.``

### Prompt 3: Implement Markdown Editor

``In the `index.html`, add a `<textarea>` for the markdown input inside the
editor section. Below the `<textarea>`, add a `<div>` to display the character
counter. In `script.js`, write JavaScript code to calculate the remaining
characters based on the input and display this in the counter div.``

### Prompt 4: Preview Functionality

``Integrate MathJax in the `index.html` file by adding its script tag in the
header. In `script.js`, write logic that updates the preview section based on
the content of the `<textarea>`. Implement a 2-second delay for the preview
update after the user stops typing.``

### Prompt 5: URL Handling

``In the `index.html`, add a button labeled "Generate URL" below the character
counter. Write JavaScript code in `script.js` to handle URL generation by
encoding the markdown content in base64 format. Display the generated URL in a
text box below the button and add a "Copy to Clipboard" button next to it.``

### Prompt 6: Styling and Responsiveness

``Open the `styles.css` file and apply basic styles for the header, footer,
editor, and preview sections. Ensure the layout is responsive for different
screen sizes using CSS media queries.``

### Prompt 7: Testing and Debugging

`Test the functionality of the math snippet sharing tool in the latest versions
of major browsers (Chrome, Firefox, Safari, Edge). Debug any issues related to
markdown rendering, character counting, or URL generation that arise during
testing.`

### Prompt 8: Deployment Preparation

``Prepare the project for deployment by ensuring that all links in `index.html`
are relative. Choose a static hosting service (e.g., GitHub Pages, Netlify) and
upload the project files to the service.``


This approach ensures that each prompt builds incrementally on the previous
work, maintaining best practices and a clear path forward without large jumps
in complexity. Each step is small enough to implement safely while moving the
project forward effectively. Let me know if there's anything you would like
to modify or add!

Here's how to set up the directory structure and the basic HTML document in `index.html`.

### Step 1: Create the Directory Structure

1.  **Create a New Directory**:

    *   Name it `math-snippet-tool`.
2.  **Inside the Directory, Create the Following Files**:

    *   `index.html`
    *   `styles.css`
    *   `script.js`

### Step 2: Basic HTML Document Structure in `index.html`

Open `index.html` and add the following basic HTML structure:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>TEST SITE</title>
    <link rel="stylesheet" href="styles.css">
    
    
</head>
<body>
    <header>
        <h1>TEST SITE</h1>
        <nav>
            <a href="#">About this site</a>
            <a href="#">Source</a>
        </nav>
    </header>
    <main>
        <div class="editor-container">
            <textarea id="markdownInput" placeholder="Type your markdown here..."></textarea>
            <div id="characterCount">2000 characters remaining.</div>
        </div>
        <div class="preview-container">
            <h2>Preview</h2>
            <div id="preview"></div>
        </div>
    </main>
    <footer>
        <p>Written by DLD &copy; <span id="currentYear"></span>. All rights reserved.</p>
        <a href="#">Report Issue</a>
    </footer>
    
</body>
</html>

You now have the basic directory structure and HTML document in place. Let me
know if you would like to proceed with the next steps!

Here’s how to update the `index.html` file to include the `<textarea>` for
markdown input and a `<div>` for the character counter. I'll also provide the
necessary JavaScript code in `script.js` to calculate the remaining characters.

### Step 1: Update `index.html`

Make sure your `index.html` includes the following code for the editor section:

<main>
    <div class="editor-container">
        <textarea id="markdownInput" placeholder="Type your markdown here..."></textarea>
        <div id="characterCount">2000 characters remaining.</div>
    </div>
    <div class="preview-container">
        <h2>Preview</h2>
        <div id="preview"></div>
    </div>
</main>

This code creates a `<textarea>` for users to input their markdown and a
`<div>` that displays the character count below it.

### Step 2: Write JavaScript in `script.js`

Now, open `script.js` and add the following JavaScript code to calculate and
display the remaining characters:

document.addEventListener('DOMContentLoaded', () => {
    const markdownInput = document.getElementById('markdownInput');
    const characterCount = document.getElementById('characterCount');
    const maxChars = 2000;

    // Update character count based on input
    markdownInput.addEventListener('input', () => {
        const inputLength = markdownInput.value.length;
        const remainingChars = maxChars - inputLength;

        characterCount.textContent = `${remainingChars} characters remaining.`;

        // Change the color of the character count if it exceeds the limit
        if (remainingChars < 0) {
            characterCount.style.color = 'red';
        } else {
            characterCount.style.color = 'gray';
        }
    });
});
