I want to make a plugin for neovim using the Python API (pynvim). The problem is I want to get the current buffer's text, updated real time. I have searched on the web and didnt find any useful (or understandable) documentation for this.

You can use pynvim to subscribe to an event in neovim. Do keep in mind that pynvim is async, but my example is using a simple while loop do demonstrate how to monitor for realtime change in a buffer and get its content.

from time import sleep
from pynvim import attach, api

nvim = attach('socket', path='/tmp/nvim')

buffer = nvim.current.buffer

event = api.nvim.Nvim.from_nvim(nvim) # use the loaded nvim session
listen = event.subscribe('TextChangedI') # refer to events https://neovim.io/doc/user/autocmd.html#events

while True:
    sleep(2)
    print(listen)
    # read and print contents of the whole buffer
    for line in range(len(buffer)):
        print(buffer[line])
