Tarantool kernel for Jupyter notebook

This is very simple implementation with a lot of known and hidden ~~gems~~ issues:

Known problems

autocomplete works correctly only in one-string cell. If someone knows how console.completion_handler() works please let me know
when output is long enough and not finished by ... then next code snippet can get output from this long output
print() output can be found in stdout of tarantool instance. If you need to get value of some variable or even function - just type it in new code cell and press Run

Run Tarantool instance in Docker

You can use preconfigured docker image of tarantool

docker run -e TNT_ADDRESS='0.0.0.0' -p 3312:3312 -p 3301:3301 -e TNT_CONSOLE_PORT='3301' -e TNT_SOCKET_PORT=3312 --rm zaraysky/tntrepo:tntsocketserver

Run tarantool locally

If you want to use local tarantool, you can run it using command

tarantool config.lua

The source code of config.lua is:

box.cfg{listen=os.getenv('TNT_CONSOLE_PORT') or 3301}

local IP = os.getenv('TNT_ADDRESS') or '127.0.0.1'
local PORT = os.getenv('TNT_SOCKET_PORT') or '3312'
box.schema.user.grant('guest', 'read, write, execute', 'universe', nil, {if_not_exists=true})
require('console').listen(IP .. ':' .. PORT)

Connect to working tarantool

Run this command in tarantool's console (REPL):

require('console').listen('127.0.0.1:3312')

Kernel installation

Please note if you have the previous version of the kernel installed you have to uninstall it using

jupyter kernelspec uninstall tntkernel

mkdir jupyter
cd jupyter
python3 -m venv venv
source venv/bin/activate
pip install jupyter tarantool

# clone it from GitHub to tntkernel folder
git clone git@github.com:zaraysky/tntkernel.git
jupyter kernelspec install tntkernel

Start it

Just run

jupyter notebook
