## Examples

Here are some examples of how to use `maktabkhooneh-downloader`:

1.  **Basic Download with Default Options:**

    If you have saved cookies, it will automatically use it to download the course video. This will save the course in the current directory

    ```bash
    maktabkhooneh-downloader download -u <your_course_url>
    ```
    for example:
    ```bash
    maktabkhooneh-downloader download -u https://maktabkhooneh.org/course/آموزش-سی-شارپ-c-mk9558/
    ```


2.  **Download with custom cookies and output directories:**

    ```bash
    maktabkhooneh-downloader download -u <your_course_url> -c /path/to/my/cookies.json -o /path/to/my/output
    ```

3.  **First time login and save cookies:**

    If you run this command and cookies file does not exist in the defined path, it will ask username, password, and confirmation to save cookies.

    ```bash
    maktabkhooneh-downloader download -u <your_course_url> -c /path/to/my/cookies.json
    ```

4.  **When cookies is not valid:**

    If you run the script with invalid cookie file, it will ask you to login again

    ```bash
    maktabkhooneh-downloader download -u <your_course_url> -c /path/to/my/invalid_cookie.json
    ```

6.  **Using relative path for cookies**

    ```bash
    maktabkhooneh-downloader download -u <your_course_url> -c ./my_cookies.json -o ./videos
    ```
    This command will save the cookies in current directory and video in the videos subdirectory.

## Explanation

### First time Login

-   If you run the script with a cookies file path that does not exist, it will prompt you for your Maktabkhooneh username and password.
-   After logging in successfully, it will ask you if you would like to save the cookies to the specified path.
-   Subsequent executions can reuse the saved cookie to make the script work seamlessly.
- If cookies are present but not valid it will ask you to relogin.

### Default Paths

-   **Cookies File:** If you don't provide the path to the cookies file, it will save `cookies.json` to suitable user data directory. The exact location will depend on your operating system (Linux, macOS, or Windows). The location is handled by `appdirs` package.
-   **Output Directory:** If you don't specify the output directory, it will save the video in the current directory the command was run from.

## Error Handling

-   The script includes basic error handling to catch exceptions that might happen during the downloading process. The error is printed to console with descriptive message.
-   You will be informed if cookies file can not be found or invalid.
-   If the course does not have any video, it will log the message into console.

## Dependencies

-   `httpx`: Used for making HTTP requests.
-   `pydantic`: Used for validating response params.
-   `tqdm`: Used for display download progress bar in output.
-   `lxml`: Used for parsing HTML content.


## Important Notes

-   This script requires a Maktabkhooneh account and access to specific course to download it.
-   The script will create output directory automatically when you are saving videos there.
