Created March 19, 2023 18:08
A couple of ChatGPT bookmarklets to summarize text from the current page, or generate text
/* jshint -W028 */
// bookmarklets to summarize the shown webpage.
// replace XXXInsertAPIKeyHereXXX with your API key to use these bookmarklets.
// this summarizes the text on the page. (We might have to cut it down to 3000 words, because the API has a limit of 3000 words.)

Created March 7, 2023 17:18
A little script to access ChatGPT from the command line
// see also https://platform.openai.com/playground?mode=complete
// command line example:
// node suggestCommand.js "Write a bash command line to do the following: log the last 3 git commits"
// Needs an API key in ~/.openaiapi , see https://beta.openai.com/docs/api-reference/authentication
// Idea for a shellscript calling that. You could also add things to the prompt there.
// #!/bin/bash
// node "$(dirname "$(readlink -f "$0")")/suggestCommand.js" "$*"

Servlet to download a resource subtree from AEM as a content-package
/**
* This is a servlet that enables to download a package of a JCR subtree without
* having to create a package in the package manager. The package is
* created on the fly, and not saved to disk / the repository, so this is
* better suited to large content trees, but valuable also for quickly downloading
* a page.
*
* CAUTION: not suitable for production, only for internal testing systems!

* Usage with curl e.g.

For testing purposes: generates various test strings with unusual characters which can be used to detect character encoding problems. Caution: this currently covers only relatively common stuff - it does not yet lead into the deeper realms of UTF like substitutes, right to left, Kanji, characters outside of 16 bit.
