.NET Code generator update from @" to """ for pattern
franckleveque: It seems that since C# 11 (.net 7) a new way is using """ at the beginning and the end of a string to allow brut string without any escaping sequence interpretation but it is not preceded by @. However I never used it. https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/strings/
Incidental find while discussing another aspect of .NET behavior.
This regex does not produce working code:
using System;
using System.Text.RegularExpressions;
public class Example
{
public static void Main()
{
string pattern = @"""
""\w+""
""";
string input = @"this is a
""test""
";
RegexOptions options = RegexOptions.Multiline;
foreach (Match m in Regex.Matches(input, pattern, options))
{
Console.WriteLine("'{0}' found at index {1}.", m.Value, m.Index);
}
}
}
We should utilize """ raw string literals instead, which would make the code above output as expected:
string pattern = """
"\w+"
""";
NOTE: the code generator will likely have to count the number of consecutive " characters inside the user's regex pattern, and simply enclose the whole shabang in +1 " characters, i.e.
string input = """""I like apples, """", and oranges.""""";
A very good suggestion, preferably with indentation as well:
string pattern = """
"\w+"
""";
