Samurai Search vs Regex Go

Search your iOS device or iCloud for text, source code, plain text files, and PDFs. Find matches inside files and preview results instantly, or open any matched file in your favourite editing or viewing app. Flexible search options: whole word, case sensitive (all file types), and regular expressions (for text files). Choose which files to include by selecting standard or custom text file types, or by searching filenames that match a pattern. Select where to search from On My iPad, iCloud Drive, or external file providers such as SMB and USB folders. When possible, the app retains saved search selections so you can quickly repeat the same searches later. If you search selected folders in iCloud Drive, matching iCloud files are synced to your device before searching, ensuring fast local results. Searching plain text files is extremely fast and memory efficient. PDF search speed depends on the document content and can be slow. Note also that PDF search may consume large amounts of memory which can cause Samurai Search to crash.

Regex Go utilized two powerful frameworks, Swift Regex and RegexBuilder, which were both introduced at WWDC22. Regular Expressions (regex) have been a popular text processing tool since the 1960s-1970s, enabling us to quickly search and match strings in text. However, using regex can be challenging due to its complex syntax and difficulty in reading and debugging. At WWDC22, RegexBuilder was introduced as a DSL (domain-specific language) to construct regex in a more readable and maintainable manner. Regex Go's aim is to make it easier for individuals who are unfamiliar with Regex to use it. Users can easily drag and drop to promptly construct their own regex without having to learn the intricate syntax and rules. This will allow more individuals to appreciate the joy of coding and increase their work efficiency.
