Pomsky, the "Next Level Regular Expressions" tool.

Here's a summary of its utility and key features:

• Simplified Syntax: Pomsky is designed to be easy to write and understand, making regular expressions more accessible. It offers a "saner syntax" compared to traditional regex.

• Instant Feedback: The application provides syntax highlighting, autocompletion, and diagnostics in VSCode, aiding in the development process.

• Built-in Tests: Pomsky includes automated tests to catch mistakes, which also serve as documentation.

• Feature-Rich: It incorporates powerful features not found in other regular expression tools.

• Great Compatibility: Pomsky expressions are transpiled to standard RegExp's, allowing their use anywhere regular expressions are supported.

• Optimized Output: Users can be confident that the generated expressions will perform well.

• Examples: The source provides a variety of examples demonstrating the syntax and capabilities of Pomsky, such as string matching, character sets, and named groups, among others. These examples include:

  • Basic string matching: 'Hello' [space]+ ('world' | 'pomsky')

  • Anchors and quantifiers: ^ % 'foo' % $ 'hello'{1,5}

  • Character classes and ranges: ['acd[]' 'p'-'s' digit]

  • Negation: !['^'] # negated

  • Unicode categories: [s U+15 U+FEFF Greek]

  • Named groups: :named(.)

  • Lookarounds: (<< 'foo' | 'bar') (!>> 'foo' | 'bar')

  • Ranges: range '0'-'255'

  • Variables: let number = '-'? [digit]+; let op = ['+-/']; number (op number)

In essence, Pomsky aims to improve the experience of creating regular expressions by providing a more user-friendly and feature-rich alternative to standard regular expression syntax.
