Code Recipes Pro

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.

In development since 2015.
