First, use RegexBuddy to define a regex or retrieve a regexp saved in a RegexBuddy library. Rely on RegexBuddy’s clear regex analysis, which is constantly updated as you build the pattern, rather than dealing with the cryptic regex syntax on your own. Detailed help on that syntax is always only a click away.
If you copied a regex written for another programming language, simply paste it into RegexBuddy, select the original language, and then convert the regex to Powershell.
If you created a new regular expression, test and debug it in RegexBuddy before using it in your PowerShell scripts. Test each regex in RegexBuddy’s safe sandbox without risking precious data. Quickly apply the regex to a wide variety of input and sample data, without having to produce that input through your application.
Finally, let RegexBuddy generate a source code snippet that you can copy and paste directly into the PowerShell command line, or your favorite PowerShell editor. Just choose what you want to use the regex for, and a fully functional code snippet is ready. You can change the names of variables and parameters to suit your naming style or the current situation, which RegexBuddy automatically remembers.
Don’t bother trying to remember which operators and parameters to use, or how to instantiate .NET classes in PowerShell. And don’t worry about properly escaping quotes and backticks. Just tell RegexBuddy what you want to do, and you will get the proper PowerShell code straight away. Anything can be done: testing a string for a match, extracting search matches, validating input, search-and-replace, splitting a string, etc.
