⚄︎ 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.

[Tip] A cute way to remember text inputs (without the remember-plugin) (self.perchance)

This likely won't be relevant to a lot of devs here, because the remember plugin does the job fine in most cases, but:

Here's a normal text input (id is not needed for this example, but is almost always needed so adding it here):

<input id="thingyInput">

And here's one which remembers what you type into it even after page refresh:

<input id="thingyInput" oninput="localStorage.thingy=this.value" value="[localStorage.thingy || '']">

Of course, the remember-plugin can do this for you, but I often find myself reaching for the above pattern for its simplicity.

localStorage is what the remember-plugin uses behind the scenes - whatever you store in it will be persisted even after page refresh. It's a built-in browser/JavaScript feature - not something that's specific to Perchance.

The || '' in [localStorage.thingy || ''] means or ''. In other words, it means or output nothing. If you want a default value for when the user loads the page for the first time, you could write [localStorage.thingy || 'blah'] which means "use whatever is in localStorage.thingy if it exists, otherwise use 'blah'"

Fair point! I think I can fix this (using MutationObserver), but it'll need to be opt-in (e.g. via an extra keyword like @includeProgrammaticInputs or something [but ideally shorter...]), since it's a "breaking change". But before I do: Another flaw is that you can't choose to only remember specific inputs, right? My memory is a little fuzzy and I can't see anything about that on the page or in the code. If so, I'll try fixing both issues at once.
