[LostNeophyte]

Description

lvim.builtin.telescope.pickers will now be autocompleted

partially fixes #3406

How Has This Been Tested?

• normal mode is just adding more steps so we should remove it
• the global theme should be more easily configurable, here's an example of how to do that: https://github.com/kylo252/lvim/blob/d381278cf22fdf6f7a7cc59da10aeced315f082f/lua/user/telescope.lua#L60-L31

I'm okay with splitting the theme refactor to another PR if you don't feel like dealing with it tho :)

theme = "ivy" here doesn't have any effect though, right? a search for telescope.defaults.theme in telescope.txt doesn't return anything.

the suggested changes would change the theme to horizontal in the affected pickers and enable the preview in some, is that change intentional?

I'd be happy to do it, not sure what to do though

correct, it's more of a way for me to keep track of which theme is being used 😅

that code block is basically my way of inlining this functions: https://github.com/nvim-telescope/telescope.nvim/blob/cea9c75c19d172d2c6f089f21656019734a615cf/lua/telescope/themes.lua#L98-L135

he suggested changes would change the theme to horizontal in the affected pickers and enable the preview in some, is that change intentional?

The theme should be controlled globally to make it more consistent. As for the preview, we should definitely drop them from this table since we don't want those changes to be global.

We can preserve the current behavior, where desired, in the mapping itself

        f = { "<cmd>Telescope find_files previewer=false theme=dropdown<cr>", "Find File" },

I'd be happy to do it, not sure what to do though

let's figure it out together :)

I've added lvim.builtin.telescope.defaults.theme and moved previewer=false to whichkey, what do you think?

and how about doing Various themes for the main UIs as a separate plugin that you require in your config and it applies some settings?

introducing a new theme should be done as a plugin, which is the idea in #2286 (comment) since it requires extra fiddling with highlight groups, see https://github.com/abzcoding/lvim/blob/575310300e72a5ff14c424e21aabe7e43baefa9e/lua/user/theme.lua#L437-L497, but I don't think we need a plugin just for selecting the theme.
