// @inject-into script

// @inject-into script injects userscript in page global scope like html <script> tag

unsafeWindow and GM* functions and objects are not available so // @grant is ignored

edit: // @require is also ignored

example:

// ==UserScript==
// @name        aaa
// @namespace   bbb
// @description ccc
// @author      ddd
// @include     /^https\:\/\/example\.com\/([?#]|$)/
// @version     0.1
// @grant       none
// @run-at      document-start
// @inject-into script
// ==/UserScript==

// logs `true, m`
let variableInPage="m";
console.log(`${window===this}, ${window.eval("variableInPage")}`);

AFAICT you can already do it by using GM_addElement.

Also, assuming the idea is to inject the entire script, how's this different to @inject-into page + @grant none ?

@inject-into page + @grant none injected script not into global scope but inside (define,module,exports)=>{...} (that is not page global scope)

window.VMin2jvmu3nh61221ua7=function(VMin2jvmu3nh61221ua7){try{with(this)((define,module,exports)=>{// ==UserScript==
// @name        aaa
// @namespace   bbb
// @description ccc
// @author      ddd
// @include     /^https\:\/\/example\.com\/([?#]|$)/
// @version     0.1
// @grant       none
// @run-at      document-start
// @inject-into page
// ==/UserScript==

// this logs `true, m`
let variableInPage="m";
console.log(`${window===this}, ${window.eval("variableInPage")}`);
})()}catch(e){VMin2jvmu3nh61221ua7(e)}};0

I see the difference. So it seems like the only reason is to access let/const in the global scope, in which case GM_addElement should be sufficient?

[tophf]

Actually, there is already a key for this feature: @unwrap so we can as well implement it for I see no reason not to.

May I confirm that this tag is only used for intentionally exposing all top level variables to the global scope? Is there any real-world use case?

[tophf]

I guess this may be also useful for people who augmented sites via extensions like user-javascript-and-css that run the code as is, not as a userscript. There are several other extensions like this. This tag will allow them to migrate to VM painlessly.
