Is it possible to modify the bufferline?

Is it possible to modify the bufferline? I'm trying to make a bufferline plugin like Neovim's lualine.

Yes, you need to create a function that will receive the buffer and return a string. This function you in the statusformatl and statusformatr options like the status and gitStatus plugins.

Use the micro.SetStatusInfoFn('pl.fn') function to set these functions:

~/.config/micro/init.lua

local micro = import('micro')

function setBomb(buf)
  return '💥'
end

function init()
  micro.SetStatusInfoFn('initlua.setBomb')  -- <plugin-name>.<function-name>
end

So you could use this function to modify your status info:

~/.config/micro/settings.json

{
    "statusformatl": "$(filename) $(initlua.setBomb)"
}
