Python client to Neovim

Build Status Scrutinizer Code Quality Code Coverage

Library for scripting Nvim processes through its msgpack-rpc API.

Installation

pip install neovim

Usage through the python REPL

A number of different transports are supported, but the simplest way to get started is with the python REPL. First, start Nvim with a known address (or use the $NVIM_LISTEN_ADDRESS of a running instance):

$ NVIM_LISTEN_ADDRESS=/tmp/nvim nvim

In another terminal, connect a python REPL to Nvim (note that the API is similar to the one exposed by the python-vim bridge):

>>> from neovim import attach
# Create a python API session attached to unix domain socket created above:
>>> nvim = attach('socket', path='/tmp/nvim')
# Now do some work. 
>>> buffer = nvim.buffers[0] # Get the first buffer
>>> buffer[0] = 'replace first line'
>>> buffer[:] = ['replace whole buffer']
>>> nvim.command('vsplit')
>>> nvim.windows[1].width = 10
>>> nvim.vars['global_var'] = [1, 2, 3]
>>> nvim.eval('g:global_var')
[1, 2, 3]
