Call this tool 'func sharp' | 'fun C#' | 'fancy sharp' as you like!

Generates boilerplate code into C# .cs files for functional programming friendly readonly structs/classes

Usage from command line:

funcsharp.exe <input file name> <output file name>

Where output file name may be the same as input file name.

Usage in the code

#region func# <you class name> <options>
  <your fields / properties>
#endregion

Possible options:

C - public constructor generation for every fields
c - private constructor generation for every fields
w - With(...) generation for every fields at once
W - WithXXX(.) generation for every fields separately
P - property getter generation for every fields"#)

Example Input:

    public struct Position2d
    {
#region func# Position2d CWwP
        public readonly double x;
        public readonly double y;
#endregion
        
        public static readonly Position2d Origo = new Position2d(0, 0);
    }

Example Output:

    public struct Position2d
    {
#region func# Position2d CWwP
        public readonly double x;
        public readonly double y;
#region #generated 56338F7B 0.1.0
        public double X { get { return this.x; } }
        public double Y { get { return this.y; } }

        public Position2d(double x, double y)
        {
            this.x = x;
            this.y = y;
        }
