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.

Need help with syntax: unique select from a string (lemmy.world)

Hello. I'm using something like this ["{red, blue, green, orange, lime}".selectMany(3).joinItems(", ")]. It works well enough, but when I try to implement uniqueSelect or consumableList it fails. These function seem to only work for lists but is there any way to select items from a string like that without repetition. Thanks!

Do you mean {red|blue|green|orange|lime} with 'shorthand lists'?

Well, it is because "{red|blue|green|orange|lime}" is only one and is a string. You can use .selectMany() because, it would essentially select the same string multiple times, and when it is evaluated by the engine it would then select from those items in the string.

You can't use .selectUnique() since it is a single item, a single string. Same with .consumableList since it isn't a list, it is a string.

Best way is to have those into a list themselves:

// Regular
colors
  red
  blue
  green
  orange
  lime

colorsV2 = {red|blue|green|orange|lime} // Shorthand list

And then, you can use those .selectUnique and .consumableList methods like so [colors.selectUnique(3).joinItems(", ")] or [x = colorsV2.consumableList, ''] [x.selectOne], [x.selectOne], [x.selectOne].

Thanks, VioneT, it's not the first time you help me. I understand the mistake now. I need a list, not a choice of one. But is there a way to create the following example: "one,two,three,four".consumableList.select(3)? It should have many items even though it's a string? This example example doesn't work, of course. I just don't wanna create infinite lists for one time use.

Sadly, lists created from a string doesn't work like that. If you want to create a list inline, you can do this instead.

[createPerchanceTree("list = {one|two|three|four}").list.selectUnique(3).joinItems(", ")]
// Create a list with `createPerchanceTree` with the name 'list' and the syntax `list = {one|two|three|four}`
// Access the new list with `.list` where `list` is the name of the list that is created.
// Select unique items from that list with `.selectUnique`
// join them with `.joinItems`

// Here's with consumableList
[x = createPerchanceTree("list = {one|two|three|four}").list.consumableList, x.selectOne] [x.selectOne]

I would still recommend it to be on the list forms that I've previously shown for readability and refactorability since if you have many of those one lines, it makes it hard to debug/see problems.
