Summary of the new feature / enhancement

As a user I want to be able to convert a user provided PowerShell wildcard pattern into a regex pattern for use in programs that accept regex.

Proposed technical implementation details (optional)

It looks like there is already a converter for this but just needs to be made public.

PowerShell/src/System.Management.Automation/engine/regex.cs

Lines 79 to 86 in 60dc724

internal string PatternConvertedToRegex
{
get
{
var patternRegex = WildcardPatternToRegexParser.Parse(this);
return patternRegex.ToString();
}
}

PowerShell/src/System.Management.Automation/engine/regex.cs

Lines 936 to 953 in 60dc724

/// <summary>
/// Parses a <paramref name="wildcardPattern"/> into a <see cref="Regex"/>
/// </summary>
/// <param name="wildcardPattern">Wildcard pattern to parse.</param>
/// <returns>Regular expression equivalent to <paramref name="wildcardPattern"/></returns>
public static Regex Parse(WildcardPattern wildcardPattern)
{
WildcardPatternToRegexParser parser = new WildcardPatternToRegexParser();
WildcardPatternParser.Parse(wildcardPattern, parser);
try
{
return ParserOps.NewRegex(parser._regexPattern.ToString(), parser._regexOptions);
}
catch (ArgumentException)
{
throw WildcardPatternParser.NewWildcardPatternException(wildcardPattern.Pattern);
}
}
