linecast 1.1.0

Terminal weather, solar arc, and tide visualizations

linecast

Terminal weather, solar arc, and tide visualizations. Pure Python, zero dependencies.

Three commands that turn your terminal into a living dashboard — temperature-colored braille curves, half-block pixel art, true color gradients, and Nerd Font icons. All data comes from free public APIs with no keys required.

Commands

weather — Current conditions, hourly braille temperature curve, 7-day forecast with color range bars, precipitation sparkline, natural language comparisons, and NWS/Environment Canada weather alerts.

sunshine — Solar arc inspired by the Apple Watch Solar face. Shows the sun's position on its daily arc with sky color gradients, day length with daily delta, and moon phase.

tides — NOAA tide predictions rendered as an ocean-themed half-block chart with gradient fill, current water level, and high/low extremes.

All three support --live for a full-screen auto-refreshing display. sunshine and tides also support arrow-key time scrubbing.

Install

pip install linecast

Or with a Homebrew tap:

brew tap ashuttl/linecast
brew install linecast

Usage

weather                          # current location via IP geolocation
weather --location 44.54,-68.42  # specific coordinates
weather --search québec          # find coordinates by city name
weather --celsius                # metric units (°C, km/h, mm)
weather --live                   # full-screen, auto-refresh

sunshine                         # solar arc for today
sunshine --live                  # full-screen with time scrubbing

tides                            # nearest NOAA station
tides --station 8413320          # specific station ID
tides --search "Bar Harbor"      # find stations by name
tides --live                     # full-screen

Weather alerts

Alerts are sourced automatically based on your location:

• US — National Weather Service (api.weather.gov)
• Canada — Environment and Climate Change Canada (api.weather.gc.ca)

Other regions get forecasts but no alerts yet.

Environment variables

Variable	Description
WEATHER_LOCATION	Default lat,lng for weather (e.g., 44.54,-68.42)
TIDE_STATION	Default NOAA station ID for tides (e.g., 8413320)
WEATHER_UNITS	Set to metric for Celsius, km/h, and mm (same as --celsius)
LINECAST_ICONS	Set to emoji to use standard emoji instead of Nerd Font icons

Requirements

• Python 3.10+
• A terminal with true color support (iTerm2, Ghostty, Kitty, WezTerm, etc.)
• A Nerd Font for best icon rendering (optional — use --emoji for standard emoji fallback)
• macOS or Linux (uses termios for live mode)
