How to close the current buffer using cokeline?

[niamleeson]

Cokeline is nice since it focuses an available buffer when it closes. I'd like to keymap to close the current buffer. How can I get the current buffer so I can call buffer:close()?

[niamleeson]

I was able to achieve it like this. Is this recommended?

vim.keymap.set('n', '<leader>bd', function()
  local lazy = require 'cokeline.lazy'
  local state = lazy 'cokeline.state'
  local curbufnumber = tonumber(vim.fn.bufnr '%')

  local target_buffer = vim.tbl_filter(function(buffer)
    return buffer.number == curbufnumber
  end, state.visible_buffers)[1]

  if not target_buffer then
    print 'Current buffer not found'
    return
  end

  target_buffer:delete()
end, { desc = 'close buffer' })

You can use require('cokeline.buffers').get_current() to simplify things.

Thank you!

Also there's no need to use cokeline.lazy in mappings, that just exists to improve the plugin's startup time. In this case it will just be wasting memory because it creates a table and metatable with each call to lazy.

Thanks, I needed this too. Perhaps add it to the documentation?
