This is more like a POC. While the base features work, the user experience might be a little ruff. I might come back to reimplement this using Textual

Retro on the commandline

Retro-CLI uses ngrok to setup a local server and generate an invitation code for others to join. Only the host needs an ngrok.com account.

Features

• Host or join retro
  • Add item in HAPPY, NEUTRAL, or BAD column
  • Remove item
  • Move item
  • Mark item as done (strike through not visualized in Jetbrains IDEA terminals)
• Connection via ngrox.com
• End-to-End encryption

Installation

Requires Python 3.8+

brew install python
# or even better, use pyenv
brew install pyenv
pyenv install 3.9.0

Install cli

pipx install git+https://github.com/eruvanos/retro-cli.git#egg=retro 

# or with pure pip

pip install git+https://github.com/eruvanos/retro-cli.git#egg=retro

This will also install ngrok on your path

Usage

Start as host

Configure your NGrok auth token. (Register at https://ngrok.com to get it) Starts the storage backend and generates an invitation code, which is shown in the console.

ngrok authtoken <auth token>

retro -s

# to only start the server, without the retro UI
retro -so

Join a host

Starts the app and asks for the invitation code of the host.

retro

Shortcuts

• CTRL + q - Exit
• CTRL + r - Request data from server (Refresh)
• CTRL + p - Ping server and print latency

Commands

Add a new item

You cann add items to the retro board by typing in your text, tusing a prefix to assign the item to a column.

Prefix:

• + Happy
• . Neutral
• - Sad

Move an item

mv <item id> <column prefix>

Toggle item done-state

! <item id>

Remove an item

rm <item id>

Missing

• persist retro items on host, so a restart doesn't kill them
• use Textualize
  • bring mouse support
• show help within the app
• add tests!
