$ show ttytm/wthrr-the-weathercrab
wthrr-the-weathercrab is a terminal-based weather companion written in Rust. It fetches current weather, hourly/daily/weekly forecasts, and historical data from the Open-Meteo API. The application supports configurable units, localization (via Google Translate API), and multiple display styles (border styles, graph types, color themes). It uses a modular architecture with clear separation of concerns: API abstraction, CLI argument parsing, configuration management, weather data fetching, and terminal rendering. The codebase demonstrates solid Rust practices including async/await, derive macros, and comprehensive testing. Notable features include a sophisticated Unicode graph renderer for temperature trends and a flexible localization system that can auto-translate strings. The project is actively maintained with recent commits and a responsive issue tracker.
The LLM identified 2 files worth highlighting for reuse:
A self-contained module for rendering temperature graphs using Unicode block characters. It supports multiple graph styles (solid lines, slim lines, dotted, custom) and row spans (single/double). The algorithm calculates glyph indices based on temperature ranges and produces smooth-looking graphs. This component is isolated (depends only on GraphOpts) and could be extracted as a reusable library for any CLI tool needing sparkline-like visualizations.
A clean implementation of box-drawing characters for terminal borders. It defines BorderStyle enum (rounded, single, solid, double) and provides methods to generate top/bottom edges and separators. The module is self-contained and demonstrates a straightforward pattern for rendering styled borders in terminal applications. Could be reused in any Rust CLI project requiring decorative boxes.
