Perchance - Create a Random Text Generator

⚄︎ Perchance

This is a Lemmy Community for perchance.org, a platform for sharing and creating random text generators.

Feel free to ask for help, share your generators, and start friendly discussions at your leisure :)

This community is mainly for discussions between those who are building generators. For discussions about using generators, especially the popular AI ones, the community-led Casual Perchance forum is likely a more appropriate venue.

See this post for the Complete Guide to Posting Here on the Community!

Rules

1. Please follow the Lemmy.World instance rules.

2. Be kind and friendly.

  • Please be kind to others on this community (and also in general), and remember that for many people Perchance is their first experience with coding. We have members for whom English is not their first language, so please be take that into account too :)

3. Be thankful to those who try to help you.

  • If you ask a question and someone has made a effort to help you out, please remember to be thankful! Even if they don't manage to help you solve your problem - remember that they're spending time out of their day to try to help a stranger :)

4. Only post about stuff related to perchance.

  • Please only post about perchance related stuff like generators on it, bugs, and the site.

5. Refrain from requesting Prompts for the AI Tools.

  • We would like to ask to refrain from posting here needing help specifically with prompting/achieving certain results with the AI plugins (text-to-image-plugin and ai-text-plugin) e.g. "What is the good prompt for X?", "How to achieve X with Y generator?"
  • See Perchance AI FAQ for FAQ about the AI tools.
  • You can ask for help with prompting at the 'sister' community Casual Perchance, which is for more casual discussions.
  • We will still be helping/answering questions about the plugins as long as it is related to building generators with them.

6. Search through the Community Before Posting.

  • Please Search through the Community Posts here (and on Reddit) before posting to see if what you will post has similar post/already been posted.

[text-to-image] Ideas (self.perchance)

promptOptions.context Send in a JS object or a list as a context the prompt has access to. Perhaps options to overload the window (falls through to the window if a name isn't found within the context), or completely contained (only things within the context can be accessed: avoids any name clashing issues).

image({ plain_object }) Allow a normal JS object to be used. Currently the plugin relies on list properties here and there, which means it breaks when a simple JS object is sent even if it has the same exact used properties.

As JS is used to create these images in a lot of generators, this would cut out the need for the engine to get involved and generate the promptOptions object at all. And the creator doesn't have to worry about how the lists work to be able to use the image generator.

promptOptions.select() When a button is clicked to "select" a particular generated image's settings... if there's a .select() function available, call it with everything to do with that generation: prompt object, etc. Maybe if there is no such function, don't show that button.

This could be used to set up the generator's textarea and other options in whatever way the creator sees fit. Or even to use this function for any other thing.

We can sort of half do this by giving each generation an id, and adding our own button next to it. And I think we can get some sort of info about a generation from its iframe? Maybe? Not sure.

But anyway, this would be a simple way of reaching in and out of the generation iframes.

Show prompt while loading: and just an idea to show the text prompt/negative prompt while the image is loading. It's useful as a creator/user to see what the prompt is that's actually generated--and nip it in the bud if we can see it's malformed or bugged in some way. Just an idea.

@[email protected] Started making my own image-gen page now. And got context working using this code:

var root = createPerchanceTree(code_input.value + `
prompt=${prompt_input.value.replaceAll("\n", " ")}
negativePrompt=${negativePrompt.value.replaceAll("\n", " ")}
`);

var settings = {
      prompt: root.prompt.evaluateItem,
      negativePrompt: root.negativePrompt.evaluateItem
...
};

See what I mean? This way, the prompt is evaluated against just whatever code the user has set up for it to use, and has no access to the page's root or code at all. It's safer because of that, is what I was talking about. (Apart from [window.root] or something I guess?)

Also, they just have full perchance capabilities, and can use any names they wish to.

Ah I see what you mean. Sounds like you basically want an "isolated" version of createPerchanceTree? The way I do something similar on perchance.org/ai-character-chat (where bots can have customCode which could be malicious for shared characters, and so needs to be sandboxed) is to create an iframe. Open that page and ctrl+f for evaluatePerchanceTextInSandbox in the list editor. I think you should actually be able to just copy-paste that function and it'll work - I definitely won't make backwards-incompatible changes to /ai-character-chat-sandboxed-executor, since forks of /ai-character-chat are relying on it. But you may need to make some changes depending on the specific thing(s) you're trying to achieve.

But if I understand your request correctly, the "real" solution to this will probably require waiting for the ShadowRealm proposal to become available in all major browsers, since otherwise it has to be an async call, which is annoying. ShadowRealm is finally making solid progress lately, so I'm hopeful that we'll get it in Chrome/Edge within a year or so. Firefox and Safari may take longer though. I think it may be possible to use something like this: https://github.com/endojs/endo/blob/master/packages/ses/README.md but I'm not sure - seems fragile to new browser features and stuff, so would probably need to be kept up to date to maintain the security boundary (maybe not - I'm not entirely sure how it works).

Yes, exactly. I've actually been able to do this with just createPerchanceTree. They can probably mess with the window--that's up to them. But at least they cannot access the main generator's properties and such. And this also means you can give people full perchance coding abilities, without the requirement of only all-caps property names and polluting the window namespace and such.

I've integrated it into my advanced text to image plugin :)

Oh, nice! I might steal some of these ideas eventually ^^'
