#483 Indentation inside string

[Soren Pingel Dalsgaard]

AStyle 3.1 will change the contents of strings during indentation.
public static string EnvSetup => $"{Unsetr} set PATH={string.Join(";", EnvironmentPaths)};%PATH%";
becomes
public static string EnvSetup => $"{Unsetr} set PATH={string.Join("; ", EnvironmentPaths)};%PATH%";
where there is an extra space added after the ";" in the middle of the string.

Hi, I know it is an old issue and maybe no longer relevant but which syntax supports this kind of strings? For astyle these are just two strings split by a single semicolon.

This is string interpolation in C#.
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated

It was introduced in version 6.
https://www.w3schools.com/cs/cs_strings_interpol.php

Seemingly, interpolation can also be nested, see following examples:

public class Test
{
    public static void Main()
    {
        const string name = "World";
        // Simple C# String interpolation:
        Console.WriteLine($"Hello {name}!");
        // C# String interpolation with string literals embedded:
        Console.WriteLine($"Hello {"*"+name+"*"}!");
        // Recursive C# String interpolation:
        Console.WriteLine($"Hello {"*"+name+ $"{ name+name}" }!");
    }
}

You can test a fix in the latest 3.2 beta 3 release.
