Assistant: Hello! How can I assist you today?
User: may u generate a prompt for managing obsidian
Assistant: Certainly! Here’s a prompt to help you manage your notes and organization in Obsidian:

---

**Obsidian Management Prompt:**

**Title:** Organizing Your Knowledge Base in Obsidian

**Objective:** Create a structured and efficient system for managing your notes in Obsidian.

1. **Define Your Purpose:**
   - What is the primary purpose of your Obsidian vault? (e.g., personal knowledge management, project tracking, research, journaling)
   - List the main topics or areas of interest you want to cover.

2. **Create a Folder Structure:**
   - Design a folder hierarchy that reflects your main topics. For example:
     - 📁 Projects
     - 📁 Research
     - 📁 Personal Development
     - 📁 Journals
   - Consider using subfolders for more specific categories.

3. **Develop a Tagging System:**
   - Identify key tags that will help you categorize and find notes easily. For example:
     - #project
     - #idea
     - #reference
     - #journal
   - Decide on a consistent format for tags.

4. **Linking Notes:**
   - Think about how you can interlink your notes. Identify key concepts that can be connected.
   - Create a few example notes and practice linking them using Obsidian’s markdown syntax.

5. **Daily/Weekly Review:**
   - Set a schedule for reviewing your notes. How often will you revisit and reorganize your notes?
   - What criteria will you use to determine if a note needs updating or if it can be archived?

6. **Utilize Plugins:**
   - Explore Obsidian plugins that can enhance your workflow. Consider plugins for:
     - Daily notes
     - Calendar integration
     - Graph view
     - Task management
   - Choose a few plugins to experiment with and see how they fit into your system.

7. **Reflect and Adjust:**
   - After a month of using your system, reflect on what’s working and what isn’t.
   - Make adjustments to your folder structure, tagging system, or linking strategy as needed.

Feel free to modify this prompt to better suit your needs! Happy note-taking!
User: what is the meanig of rescinded in chinese
Assistant: The word "rescinded" can be translated into Chinese as "撤销" (pinyin: chèxiāo). It means to revoke, cancel, or annul something, such as a decision, agreement, or contract. If you need further context or examples, feel free to ask!
User: i am using nextjs page router, how to make all of my page become dynamic?
Assistant:  ToTo make all your pages dynamic in a Next.js project using the **Pages Router**, you generally create dynamic route segments using square brackets (`[param]`). However, if you want to catch *all* routes dynamically (like a catch-all route), Next.js provides **catch-all routes**.

Here's how you can do it:

### Step 1: Create a catch-all route file

In your `pages` directory, create a file named:

```
pages/[...slug].js
```

`[...slug].js` will catch **all** routes that don't match any other page files.

### Step 2: Access the dynamic segments

Inside `pages/[...slug].js`:

```jsx
import { useRouter } from 'next/router';

export default function DynamicPage() {
  const router = useRouter();
  const { slug } = router.query;

  // `slug` is an array of all path segments (or undefined during pre-render)
  if (!slug) return <p>Loading...</p>;

  return (
    <div>
      <h1>Dynamic Page</h1>
      <p>Slug segments: {slug.join(' / ')}</p>
    </div>
  );
}
```

---

### How this works:

- If you visit `/about`, `slug` will be `['about']`.
- If you visit `/blog/post-1`, `slug` will be `['blog', 'post-1']`.
- If you visit `/some/long/path/here`, `slug` will be `['some', 'long', 'path', 'here']`.

---

### Notes

- This setup overrides specific routes except those that are explicitly defined by files like `pages/index.js` or any other static routes you have.
- If you want **all pages** to be dynamic, avoid creating static pages in `pages/` except perhaps `index.js`.

---

If your goal is to handle virtually all page requests dynamically, this is the recommended pattern with the Next.js Pages Router. If you want to go deeper — e.g., fetch data based on the path or render different components dynamically — just extend this component logic.

Let me know if you want an example including server-side data fetching!
User: next js page router dont prerender as static html
Assistant: In Next.js **Pages Router**, whether a page is pre-rendered as static HTML (Static Generation) or rendered on the server on each request (Server-Side Rendering) depends on how you implement data fetching in that page:

### 1. **Static Generation (pre-render as static HTML)**  
Occurs if:
- You export a `getStaticProps` function from your page, optionally combined with `getStaticPaths` for dynamic routes.
- Or no data fetching method is used, and the page is static by default.

This means the HTML is generated at build time and served as a static file.

---

### 2. **Server-Side Rendering (no static HTML at build time)**  
Occurs if:
- You export a `getServerSideProps` function in your page.
- Next.js will render the page on each request on the server.
- In this case, there is no static HTML generation at build time.

---

### Why might your pages **not** be pre-rendered as static HTML?

- If your dynamic page uses `getServerSideProps`, Next.js disables static generation and renders pages at request time.
- If your dynamic route uses fallback behavior in `getStaticPaths` such as `fallback: 'blocking'` or `fallback: true`, some pages might be generated at runtime on the first request.
- If you don't use any data fetching (`getStaticProps`, `getServerSideProps`) but your page relies on client-only features like `useEffect` to fetch data, the HTML will be static but the page content comes from client JS.

---

### How to make pages **pre-render as static HTML**:

- Use `getStaticProps` (and `getStaticPaths` if dynamic).
- Avoid `getServerSideProps`.
- For fully dynamic pages, use `getStaticPaths` with `fallback: false` or an array of known paths.
- If you want dynamic behavior but still want static generation for known paths, combine these with **Incremental Static Regeneration (ISR)** by adding a `revalidate` field in `getStaticProps`.

---

### Summary Example for Dynamic Static Page:

```js
// pages/[...slug].js

export async function getStaticPaths() {
  return {
    paths: [
      { params: { slug: ['about'] } },
      { params: { slug: ['blog', 'post-1'] } },
    ],
    fallback: false,  // only build the specified paths at build time
  };
}

export async function getStaticProps({ params }) {
  // fetch data based on params.slug here
  return {
    props: {
      slug: params.slug,
      // other props here
    },
    revalidate: 60,  // optional ISR: regenerate page every 60 seconds
  };
}

export default function DynamicPage({ slug }) {
  return <div>Slug: {slug.join(' / ')}</div>;
}
```

---

If you don't use `getStaticProps` or `getServerSideProps`, Next.js will try Static Generation without any data.

If you want me to help you convert a specific page into a statically generated dynamic page, please share your code!
User: in js, how to only get the base path
Assistant: To get only the **base path** (i.e., the first segment of a path) from a URL or path string in JavaScript, you can do the following:

### Example 1: Using a URL string

```js
const url = '/blog/post-1/first-article';

// Remove leading and trailing slashes, then split by '/'
const segments = url.replace(/^\/|\/$/g, '').split('/');

// Get the base path (first segment)
const basePath = segments[0] || '';

console.log(basePath);  // Output: "blog"
```

### Explanation:
- `replace(/^\/|\/$/g, '')` removes leading and trailing slashes.
- `split('/')` splits the path into segments.
- `segments[0]` is the base path (first segment).

---

### Example 2: Using `window.location` (browser environment)

If you want to get the base path from the current page URL:

```js
const pathname = window.location.pathname;  // e.g. "/blog/post-1/first-article"

const basePath = pathname.replace(/^\/|\/$/g, '').split('/')[0] || '';

console.log(basePath);
```

---

### Edge cases:

- If the path is just `/` or empty, this will return an empty string.
- You can add a fallback if needed:

```js
const basePath = segments[0] || '/'; // fallback to '/' if empty
```

---

Let me know if you want a function that extracts the base path from any URL string or pathname!
