Regex Hero
What it is
Regex Hero is a regular expression tester for .NET patterns. Its web tester lets users write and check expressions in real time, with matches highlighted as they type. Patterns behave the same way as they do in .NET applications. The editor includes syntax highlighting and code completion, and users can generate C# and VB.NET code from their expressions. A .NET regular expression reference is available on the site. The community .NET Regex Library lists 179 expressions in categories such as email, validation, CSV, and password. Regex Hero is available on the web and Windows, and its tester page links to a Microsoft Store download. The home page says a Mac version is not yet available. Support comes from creator Steve Wortham by email and through a forum for ideas and bug reports. The privacy policy says information such as name, email address, and browser information may be collected for analytics. It also says user ratings, reviews, and feedback may be displayed, reused, and distributed.
