shot-scraper 1.8. I've added a new feature to shot-scraper that makes it easier to share scripts for other people to use with the shot-scraper javascript command.

shot-scraper javascript lets you load up a web page in an invisible Chrome browser (via Playwright), execute some JavaScript against that page and output the results to your terminal. It's a fun way of running complex screen-scraping routines as part of a terminal session, or even chained together with other commands using pipes.

The -i/--input option lets you load that JavaScript from a file on disk - but now you can also use a gh: prefix to specify loading code from GitHub instead.

To quote the release notes:

shot-scraper javascript can now optionally load scripts hosted on GitHub via the new gh: prefix to the shot-scraper javascript -i/--input option. #173

Scripts can be referenced as gh:username/repo/path/to/script.js or, if the GitHub user has created a dedicated shot-scraper-scripts repository and placed scripts in the root of it, using gh:username/name-of-script.

For example, to run this readability.js script against any web page you can use the following:

shot-scraper javascript --input gh:simonw/readability \
  https://simonwillison.net/2025/Mar/24/qwen25-vl-32b/

The output from that example starts like this:

{
    "title": "Qwen2.5-VL-32B: Smarter and Lighter",
    "byline": "Simon Willison",
    "dir": null,
    "lang": "en-gb",
    "content": "<div id=\"readability-page-1\"...

My simonw/shot-scraper-scripts repo only has that one file in it so far, but I'm looking forward to growing that collection and hopefully seeing other people create and share their own shot-scraper-scripts repos as well.

This feature is an imitation of a similar feature that's coming in the next release of LLM.
