DotStuff 0.0.0-pre.0

About

DotStuff is a source-only NuGet package that adds few helpful extensions for method chaining in C#.

Source-only here means that DotStuff adds a single, hidden C# file to your project. There is no extra DLL to ship. For libraries, there is no extra dependency that referencing projects see. This is ideal for a micro-package like DotStuff that consists of a single file. The file itself is written carefully to avoid conflicts with existing code.

Installation

Install this NuGet Package in your project.

Usage

// Right assign
foo.AssignTo(out bar)       // => bar = foo;

// Right coalesce
foo.CoalesceWith(ref bar)   // => bar ??= foo;

// Tap
foo.Tap(action);            // { action(foo);       return foo; }
foo.Tap(action, x)          // { action(foo, x);    return foo; }
foo.Tap(action, x, y)       // { action(foo, x, y); return foo; }
// ... up to 3 extra arguments

// Apply
foo.Apply(function);        // => function(foo);
foo.Apply(function, x)      // => function(foo, x);
foo.Apply(function, x, y)   // => function(foo, x, y);
// ... up to 3 extra arguments

Options

DotStuff responds to the following preprocessor symbols.

• DOTSTUFF_DISABLE

  Define this symbol to disable DotStuff completely.

• DOTSTUFF_ENABLE_CODE_COVERAGE

  Define this symbol to include the DotStuff extension methods in code coverage. By default, the extension methods are excluded.

• DOTSTUFF_HAS_CSHARP_8_OR_GREATER

  If this symbol is defined, DotStuff uses C# 8.0 features, such as the ??= operator required for CoalesceTo.

  This symbol is defined by default for target frameworks that use C# 8.0 or later by default: .NET 5.0, .NET Core 3.0, .NET Standard 2.1, and later.

  Define this symbol to use C# 8.0 features on older target frameworks. Make sure to configure the language version of the project to C# 8.0 or later.

• DOTSTUFF_HAS_NULLABLE

  If this symbol is defined, DotStuff uses nullability attributes.

  This symbol is defined by default for target frameworks that provide these attributes: .NET 5.0, .NET Core 3.0, .NET Standard 2.1, and later.

  Define this symbol to use nullability attributes on older target frameworks. Some source of those attributes will be required. One easy option is to use Manuel Römer's Nullable package.
