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.

There are words you need in letters or long sentences, but copying, pasting, editing, selecting the parts you want... have you often found it difficult? The 'Smart Parsing' app solves the problem. 'Smart Parsing' is a powerful app that allows you to easily extract/replace/copy desired items in strings. 1. Smart Parsing * Displays text copied to the clipboard as a list of results matching the patterns registered in the app. * Splits the text copied to the clipboard using the specified delimiters and displays it as a list. * When you select the parsed result, it is automatically copied to the clipboard. * When there are multiple texts you want to copy, you can copy the desired text by continuously selecting it in multi-selection mode. * When copying after multiple selections, you can set it as a separator to be inserted between texts. 2. Individual Parsing * Up to 5 pattern values are displayed, and patterns can be applied one by one. * You can check in advance how the pattern will be applied. (Different colors for each pattern). * You can convert text searched with a pattern to another value. * It provides 'Direct Mode', which reduces the process of pasting, pressing a pattern, and copying to one touch. 3. Pattern Settings and Regular Expression Recommendations * Both pattern settings and detailed settings can be set by the user. * Since setting up patterns (regular expressions) may seem difficult, we provide a 'recommendation' function. 4. Copy history management * Provides the ability to re-copy copied content through parsing. 'Smart Parsing' uses regular expressions (an expression of a string pattern used to find or match a specific pattern within a string), and provides a regular expression recommendation service for convenient registration. Q: There is no desired pattern in the regular expression recommendation service? A: If you contact us within the app (regular expression recommendation - top right - email icon) or send us your pattern information to the email below, we will help you create a regular expression.
