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
