Dynamically resize search-results and preview panes

[Sebastian-Nielsen]

Is it possible to set up a mapping so that I dynamically can resize the proportion between the search-results pane and preview pane?

winoptscan be function, which means you can give per-picker different size.

require('fzf-lua').setup {
  winopts = function() return {...} end,
}

Or you are talking about resize the preview window while using one picker?

While using one picker, how do I dynamically resize the proportion between the search-results pane and the preview pane. In the same way I have the ability to dynamically resize the proportion between two split panes in nvim (you know: :vs, :vertical resize 40).

Not feasible now. (since fzf cannot resize preview? )

But I found there's a toggle-fullscreen maybe also useful, I think.

keymap = {
    builtin = {
      ["<F2>"]        = "toggle-fullscreen",

You can do so with a custom binding, first try out the rotates, F5/F6 it can rotate the preview in a circle changing the alignment of the preview pane, this should give you more space to see the results if that’s what you’re after, you can also toggle the preview with F4 or go fullscreen with F2 as @nenahp mentioned.

As for your specific request you can do it but you’d need to implement your own bind, I didn’t test this yet but this is how I’d do it:

• use the winopts.on_create event to create your local win fzf win keymap using vim.keymap.set
• get the window object from FzfLua.util.fzf_winobj()
• Change the inner winopts values to whatever new ratios you want
• Call redraw()

You can see how it’s done in the preview rotation function so you can reuse some of this code:
