js2bookmark

Did you know you can run custom scripts on websites to make them do what you want without installing an extension?

This script turns your JavaScript code into single link that you can save as a bookmark in Chrome/Safari/Firefox

Then, just click on it to run your code on the current page.

oh and it even works on your phone

i used it for my export-tweeters script

let usage=`
	USAGE:

		js2bookmark.js <a.js> <b.js> ...

			INPUT : path to the JavaScript file(s) you want to inject into the browser when clicking the bookmark.

			OUTPUT : raw text of bookmark link. code from each file will be encapsulated in its own wrapper function.
