RawFormatter 0.5.2

RawFormatter

A library that combines raw string literals and string interpolation introduced in C# 11, compatible with .NET Standard 2.0, to implement fast-acting template features.

Minimum Requirements

• Requires a platform with .NET Standard 2.0 or later, and Windows Vista+, Windows Server 2008+
  • Supported .NET Version: .NET Core 2.0+, .NET 5+, .NET Framework 4.6.1+, Mono 5.4+, UWP 10.0.16299+, Unity 2018.1+

Breaking Change

From 0.5.1 to 0.5.2

• Considering that the type name Switch may exist among namespaces linked by implicit reference in the BCL, change the type name to Select.

How to use

Use with conditional block

Initialize and pass instances of the If, For, Select and ForEach classes in the string interpolation interval. At this point, you can use collection initializers to implement a simplified syntax.

using RawFormatter;

...

var @namespace = "Hello";
var isEnumType = DateTime.Now.Second % 2 == 0;
var typeName = "Candidates";
var memberType = "int";
var cases = DateTime.Now.Second % 3;
var members = Enumerable.Range(0, 5).Select(x => new KeyValuePair<string, int>($"Member{x}", x)).ToArray();

var fragment =
	$$"""
	namespace {{@namespace}}
	{
		using System;

		{{new For(5) { (int i) => $"/* forloop / {i} time(s) */" } }}

		/*
		{{new Select(cases)
		{
			{ 3, (int num) => $"select case / {num} with 3" },
			{ Select.Else, (int num) => $"select default / {num}" }
		}
		}}
		*/
			
		{{new If(isEnumType)
		{
			$$"""
			public enum {{typeName}} : {{memberType}}
			{
				{{new ForEach(members) {
					(KeyValuePair<string, int> item) => $$"""
					{{item.Key}} = {{item.Value}}, /*if - true*/ /* foreach */
					"""
				}}}
			}
			""",

			$$"""
			public static class {{typeName}}
			{
				{{new ForEach(members) {
					(KeyValuePair<string, int> item) => $$"""
					// if - false && foreach
					public static readonly {{item.Value.GetType()}} {{item.Key}} = {{item.Value}};
					"""
				}}}
			}
			""",
		}}}
	}
	""";

Console.Out.WriteLine(fragment);
