Mechanize is a mature Ruby library for automating web interactions. It acts as a programmable web browser, enabling users to fetch pages, follow links, submit forms, manage cookies, handle authentication (Basic, Digest, NTLM), and support content compression (gzip, deflate, brotli, zstd). The library wraps `net-http-persistent` for connection management and `nokogiri` for HTML/XML parsing. Key architectural patterns include a pluggable parser system that maps MIME types to response handlers (e.g., `Mechanize::Page` for HTML, `Mechanize::Image`, `Mechanize::Download`), an element matching mixin for filtering links and forms, a robust cookie jar, and an authentication store. Its test suite (over 150 test files) uses a WEBrick-based mock server and servlets to simulate realistic scenarios without network calls. The library is widely used for scraping, testing, and automation in Ruby ecosystems.
This is a Craft CMS plugin that provides contact form functionality for websites. It allows users to create and submit contact forms with fields for name, email, subject, and message, with support for file attachments. The plugin processes form submissions, validates input, constructs email messages (both plain text and HTML), and sends them via Craft's mailer system. It follows a standard MVC architecture where controllers handle HTTP requests, models represent data (submission and settings), and services (Mailer) handle the core email processing logic. The plugin is extensible through events (beforeSend, afterSend) that allow other plugins to modify behavior. Key features include AJAX form submission support, configurable email templates, attachment handling with file type validation, and multi-language support.
