Clojure Recipes

An everyday Clojure reference, from immutable collections to protocols and higher-order functions. Most examples have explanatory comments. • 22 sections, including basic types, collections, records and protocols, named and anonymous functions, exception handling, regular expressions, concurrency, files, serialization, databases, algorithms, design patterns. • Language changes by version: 7 sections from Clojure 1.5 to 1.12, with before-and-after code. • Keyword and function reference: over 140 articles. Browse, search, or tap a word in the code to open its article. • SQL included: over 200 queries (JOIN, GROUP BY, subqueries, data types); more than half run on a live practice database. • Run in the app: the output appears directly below the code, no IDE or compiler needed. Most examples are runnable. Requires an internet connection. • Search covers the code itself, not just titles: type a fragment you remember and find the example. • Edit examples or add your own; your edits and examples are saved in the app. • Everything except running works offline. No account needed. Examples are curated from professional sources and checked before release: the code works and is easy to follow. FREE VERSION • 12 runs (examples and SQL combined) and 12 edits a day • Full keyword and function reference, no limits • Up to 5 examples of your own The full version unlocks every example and query, removes the limits on edits and on your own examples, and raises the daily run limits to 30 for examples and 80 for SQL. One-time purchase, no subscription. Built by a developer for developers. The CodePro project has been in active development since 2015.
