Crabfleet is a cross-platform remote desktop application that enables users to access and control computers from anywhere. The system comprises a native macOS viewer app (Swift), a web viewer (TypeScript/Preact), a Linux connector (Go, X11/Wayland capture), a Windows connector (Go, GDI), and a backend infrastructure on Cloudflare Workers (D1 database, Durable Objects for relay). It uses the VNC/RFB protocol with custom extensions for H.264/HEVC video encoding, audio streaming, clipboard synchronization, and file sharing. Authentication supports GitHub OAuth and native device-code authorization. Transport options include direct VNC, WebSocket relay via Cloudflare, QUIC, and WebRTC. The codebase is architecturally sound with clean separation of concerns, extensive test suites, and careful security patterns (bounded buffers, token fencing, safe prime validation). However, the multi-language stack (Go, Swift, Rust, TypeScript) and multiple protocol implementations increase maintenance complexity.
This repository is the open-source 'Rainbow Brackets Lite' IntelliJ IDEA plugin, a free and feature-limited version of the popular Rainbow Brackets plugin. The plugin colorizes nested brackets (round, square, squiggly, angle) with distinct colors to improve code readability, and provides additional features like rainbow indent guide lines and scope highlighting via mouse shortcuts. It is implemented as a JetBrains plugin using the IntelliJ Platform SDK, with core logic split between an Annotator (for simple leaf-elements) and a HighlightVisitor (for more accurate per-language matching via BracePairProvider extension points). The architecture follows standard IntelliJ plugin patterns: extension points for brace providers, custom text attributes, and a thorough settings UI integrated into the IDE's color scheme page. The codebase is well-structured with proper separation of concerns, utility functions (memoization, color blending), and comprehensive tests for multiple languages. While tightly coupled to the IntelliJ API, several components (BracePairProvider interface, memoization utility, color blending) demonstrate non-obvious skill and could be extracted for reuse in other JetBrains plugins or JVM projects.
