# howdoi — Instant Coding Answers from the Command Line

## Quick Use
```bash
pip install howdoi
howdoi format date python
howdoi create mass git branches
howdoi -a convert csv to json python
```

## Introduction
howdoi fetches concise answers to programming questions directly from your terminal. It scrapes top-voted Stack Overflow responses and returns code snippets, saving developers from context-switching to a browser.

## What howdoi Does
- Answers free-form programming questions with code snippets from Stack Overflow
- Returns the top-voted answer by default or all answers with the `-a` flag
- Supports colorized output with syntax highlighting
- Provides a REPL mode for interactive question sessions
- Caches responses locally to speed up repeated queries

## Architecture Overview
howdoi is a Python CLI that uses search engines to find relevant Stack Overflow threads, then parses the HTML to extract the highest-scored code blocks. It employs a local cache (file-based or optional Redis) to avoid repeated network calls. The tool can use Google, Bing, or DuckDuckGo as the search backend.

## Self-Hosting & Configuration
- Install via `pip install howdoi` or `pipx install howdoi`
- Set `HOWDOI_SEARCH_ENGINE` to choose between google, bing, or duckduckgo
- Configure cache directory with `HOWDOI_CACHE` environment variable
- Use `HOWDOI_COLORIZE=1` to enable syntax-highlighted output
- Integrate into editors via the included Emacs and Vim plugins

## Key Features
- Answers returned as ready-to-paste code snippets
- Multiple search engine backends for reliability
- Local caching reduces latency for repeated lookups
- Colorized terminal output with language detection
- Importable as a Python library for programmatic use
