haTerm - v0.1
|
|
(c) Sophia Schmidhofer
|
|
|
|
haTerm is a Terminal Based hafas client, using the ivb endpoint.
|
|
Prompt_toolkit (https://github.com/prompt-toolkit/python-prompt-toolkit) will be used to render a terminal user interface (TUI).
|
|
The application will provide routing information and station departures/arrivals.
|
|
|
|
Route planning UI.
|
|
|
|
Wrapped in a function so it can be launched from `main.py` with a shared
|
|
`HafasClient` instance from `backend.py`.
|
|
|
|
Note: This module is a minimal TUI stub. Many features are not implemented
|
|
yet (station lookup, route rendering). Add TODOs where appropriate.
