Code Recipes Pro

Look up how a task is done in a language you don't use every day, and get a working snippet. Offline, no account.

Code examples for 13 programming languages and SQL, organized by task. Look up how something is done in a language you don't use every day and get a working snippet — not a wall of theory.

About 5,000 examples in 26 sections that follow how developers think: collections, control flow, generics, concurrency, regular expressions, files, databases, serialization, algorithms, design patterns, reflection, LINQ.

LANGUAGES Swift, Kotlin, Java, Objective-C, C#, C++, Go, Rust, Python, JavaScript, TypeScript, PHP, Ruby, and SQL.

WHERE IT HELPS • Switching languages. The topic tree is identical everywhere: find the pattern you know in one language, see how it is written in another. • Interviews and exams. The tree covers the questions that come up most often. • Syntax you touch twice a year. Date formatting, regex groups, JSON serialization, thread pools, file I/O — a couple of taps instead of a search session.

WHAT'S INSIDE • Examples with the expected output shown inline, so you can check the result without running them. • A separate SQL section: 201 queries with result tables and short explanations. • Search by topic name or by a fragment of code. • Works fully offline. No account, no sign-in. • Favorites for the snippets you come back to. • Optional links to online playgrounds when you want to run something. • Light, dark or system theme; adjustable font and size; optional line numbers. • On iPad: topic list and code side by side. • Interface and content in 15 languages.
