$ show taoensso/encore
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.
The LLM identified 6 files worth highlighting for reuse:
A composable signal-handling API with levels, filters, sampling, transforms, and handler context. It is reusable as a foundation for logging, metrics, or observability subsystems and includes a `def-api` macro that generates a complete signal API with minimal boilerplate.
Provides `SummaryStats`, `SummaryStatsBuffered`, sorted numeric containers, and mergeable percentile calculations. Ideal for embedded performance monitoring or lightweight streaming analytics; it is data-source agnostic and can be extracted into any JVM/JS Clojure project.
Offers unsigned integer helpers, dynamic-length encoding, and BitSet freeze/thaw utilities. These are clean, isolated building blocks for binary protocols, serialization layers, and low-level I/O code.
A lightweight single-threaded timer service supporting scheduling, lazy/eager cancellation, and garbage collection of expired timers. It is reusable anywhere low-footprint in-process scheduling is needed without adopting a full task framework.
A fast, dependency-free Java implementation of NanoId and HexId generators. It is directly reusable from any JVM project for high-quality unique identifier generation and avoids the overhead of Clojure interop wrappers.
The core namespace: a broad, carefully engineered set of cross-platform utilities including macros, predicates, coercions, collection helpers, `LightAtom`, cache/memoization, rate limiters, async runners, environment config, Ring helpers, and ClojureScript AJAX. It is intentionally reusable as a dependency, though its scope is that of a utility grab-bag rather than a single focused pattern.
