the bookmarklet build system
bookmarkl.ink can be used to share simple javascript gists, executable in the browser and saved as bookmarklets, like a QR code creator, a reader view, or the entirety of DOOM.
to generate your own bookmarklet, write some javascript, save it as a github gist, copy the url, paste it below, and hit create.
you can assign a title and description to your bookmarklet by including //bookmarklet_title: <your title> and //bookmarklet_about: <your details> in your code, respectively.
to learn more, see the project repo.
or, open a playground.
