Just like https://violentmonkey.github.io/api/gm/</a" rel="noopener" target="_blank">Violentmonkey, but with more unsafe API.

Purplemonkey API

only the additional api from violent monkey are listed. other api are same to the violent monkey in the same version.

GM_messageExtension(id, payload)

send message to other extension's browser.runtime.onMessageExternal handler.

• id: the id of the destination extension.
• payload: the data to send. must be structure clonable.
• return: a promise resolve to the response or reject to error.

to use this api, you have to add @connect web-extension://id in the userscript's meta field. where id is the extension that you want to send message with. the special web-extension://* allow to connect to all the other extensions.

GM_webextEval(code, args)

eval string or function in violent monkey background script.

• String(code): the code is call as (function (...args) {return eval(code)})(...args), so the last statement is return.

• Function(code): code is stringify and reconstructed as function in background. stringify so any closure will not work.

  if this is a method, you should make sure that it could be stringify and reconstruct correctly.

  async could work.

• args: an argument array that structure clonable.

• return: a promise resolve to result or reject to error.
