feat: paste window open hook about kitty-scrollback.nvim

[ofseed]

I know this option, and I fixed a bug about this : ), see: #182

There's a more complicated situation in my use case. I'm using 'statuscolumn' to arrange my sign columns, there's no way to disable 'statuscolumn' except a hook to do this.

Hey @ofseed I added the callback after_paste_window_ready that has a first parameter containing the window and buffer ids of the scrollback buffer, paste window, and paste window footer. The paste window data will be in form similar to:

local paste_window_data = {
  scrollback_buffer = { bufid = p.bufid, winid = p.winid },
  paste_window = { bufid = p.paste_bufid, winid = p.paste_winid },
  paste_window_footer = { bufid = p.footer_bufid, winid = p.footer_winid },
}

I played around a bit and created this example:

require('kitty-scrollback').setup({
  {
    callbacks = {
      after_paste_window_ready = function(pastewin_data, kitty_data, opts)
        local stc = '%#ErrorMsg#%{(v:lnum%2)?" ".v:lnum:""}' .. '%#WarningMsg#%{!(v:lnum%2)?" ".v:lnum:""} '
        vim.api.nvim_set_option_value('statuscolumn', stc, {
          win = pastewin_data.paste_window.winid,
        })

        vim.keymap.set({ '' }, '<Tab>', '<Plug>(KsbToggleFooter)', {
          buffer = pastewin_data.paste_window.bufid,
        })

        if pastewin_data.paste_window_footer.winid then
          vim.api.nvim_set_option_value('statuscolumn', 'help:', {
            win = pastewin_data.paste_window_footer.winid,
          })
        end
      end,
    },
  },
})

Please let me know if you run into any issues

Hey @ofseed thanks for reporting.

Regarding adjusting window options, there are overrides exposed via:

Options	Type	Description
paste_window.winopts_overrides	fun(paste_winopts: KsbWinOpts): table<string,any>?	Paste float window overrides, see nvim_open_win() for configuration
paste_window.footer_winopts_overrides	fun(footer_winopts: KsbWinOpts, paste_winopts: KsbWinOpts): table<string,any>?	Paste footer window overrides, see nvim_open_win() for configuration

There is an example of this in Advanced Configuration Examples named ksb_example_paste_win_winopts.

But, I agree, there is no general hook if you want to do something based on the bufnr or winid. What are you trying to trigger when the paste window opens?

😅 oops, didn't realize.

Ah, I see yeah you are right.
