ljg-x-download

Download images or videos from X (Twitter) links to ~/Downloads.

Dependencies

```
yt-dlp
```
(already installed)

Execution Steps

1. Parse Input

Extract the X/Twitter URL from user input. Supported formats:

```
https://x.com/user/status/123456
```
```
https://twitter.com/user/status/123456
```

https://mobile.twitter.com/user/status/123456

URLs with query parameters (yt-dlp automatically handles tracking parameters like
```
?s=20
```
)

Resolve shortened links (t.co) first:

curl -Ls -o /dev/null -w '%{url_effective}' "SHORT_URL"

If the user does not provide a URL, use AskUserQuestion to request it.

2. Attempt Direct Download (Video Priority)

Download directly with yt-dlp without prior detection:

bash

yt-dlp -o "~/Downloads/%(uploader)s_%(id)s.%(ext)s" "URL"

If successful (video tweet), the process is complete. Proceed to step 4 to report the result.

3. Extract Images When Video Download Fails

yt-dlp may throw errors for image-only tweets. In this case, use

--dump-json

to extract image URLs:

bash

yt-dlp --dump-json "URL" 2>&1

Result Judgment:

If the JSON contains a
```
thumbnails
```
array → Extract image URLs
If the JSON is empty or throws a
```
no video
```
error → The tweet has no media, inform the user: "This tweet does not contain downloadable images or videos"
If the error contains
```
login
```
/
```
authentication
```
→ Login is required (see Troubleshooting)
Other errors → Report the specific error message

Image Download:

Extract all image URLs from the

thumbnails

array in the JSON, replace

name=small

or

name=medium

with

name=orig

to get the original image, then download them one by one:

bash

curl -L -o ~/Downloads/tweet_ID_1.jpg "https://pbs.twimg.com/media/xxx?format=jpg&name=orig"
curl -L -o ~/Downloads/tweet_ID_2.jpg "https://pbs.twimg.com/media/yyy?format=jpg&name=orig"

The file extension follows the

format

parameter in the URL (jpg/png/webp).

4. Report Results

After downloading is complete, use

ls -lh

to list the downloaded files: file name, size, and path.
