taoensso/encore is a foundational Clojure/ClojureScript utility library rather than an end-user application. It provides a broad collection of general-purpose cross-platform primitives: macros for control flow and aliasing, predicates and coercions, collection/string/time helpers, concurrency constructs, caching and memoization, rate limiting, async runners, environment configuration, Ring helpers, and ClojureScript AJAX support. The core functionality lives in a single large namespace, with additional experimental namespaces for byte manipulation, statistics, signal handling, and timers. It is designed to be embedded in other libraries and applications, not run standalone. The architecture is modular at the namespace level: `taoensso.encore` is the core grab-bag, while `taoensso.encore.bytes`, `taoensso.encore.stats`, `taoensso.encore.signals`, and `taoensso.encore.timers` provide focused, self-contained subsystems. A small Java class supplies high-performance NanoId/HexId generation. The code is heavily optimized for cross-platform behavior and performance, using reader conditionals, custom deftypes, CAS loops, and transient collections. It has a robust test suite and CI coverage for Clojure, ClojureScript, GraalVM, and Babashka. Although it contains statistical and byte-level utilities that could support data work, the repository is not a data pipeline or research project. There are no datasets, notebooks, or ETL flows. The stats module is a reusable library component, not an analytical schema. This is a dependency-first library with high reuse value for Clojure developers needing battle-tested utilities.
JSPrintManager is a client-side printing and scanning solution enabling web applications to bypass browser print dialogs by communicating with a native client application via WebSocket. The system consists of a core JavaScript library (JSPrintManager.js) that provides APIs for creating print/scan jobs, managing printer connections, and handling device-specific communication protocols (serial, USB, Bluetooth, TCP/IP, HID, IPP). A React-based demo application showcases features including printing various file formats (PDF, images, Office documents), raw printer command languages (ZPL, ESC/POS), bidirectional device communication, printer monitoring, and scanning functionality. The solution requires installation of a lightweight native client on user machines to establish the WebSocket bridge between browser and hardware devices.
