# Fluent.Extensions
Fluent.Extensions is a netstandard class library that supports programming against [fluent interfaces](https://en.wikipedia.org/wiki/Fluent_interface). Its primary purpose is to ease the transition to a more fluent programming style as part of every [AutoFluent](https://github.com/pragmatrix/AutoFluent) package.
## Installation
Fluent.Extensions can be installed separately [via NuGet](https://www.nuget.org/packages/Collections.Fluent/).
## Contents
### Generic collections extension methods
Fluent.Extensions contains all extension methods defined in the [Collections.Fluent project](https://github.com/pragmatrix/Collections.Fluent) that are used to modify generic collections inside a method chain. They are available as soon the namespace System.Collections.Generic is used.
### General purpose methods
The following general purpose extension methods are defined in the global namespace, they are available as soon Fluent.Extensions is referenced by your project.
#### Do()
The `Do()` extension method can be inserted inside a method chain to call back into lambda expression or a method. The lambda expression is expected to have exactly one parameter that receives the current object of the method chain. `Do()` always returns the current object.
For example:
var x = 10;
1.Do(v => x += v)
.Do(v => x += v*2);
Sets x to 13.
#### Pipe()
The `Pipe(f)` extension calls the function *f* with the current object of the method chain and continues with the function's result.
For example:
var x = 10.Pipe(a => a * a);
Sets x to 100.
### AutoFluent specific extension methods
These are extension methods used by [AutoFluent](https://github.com/pragmatrix/AutoFluent) generated packages.
#### DemoteSender()
The `DemoteSender()` extension method forwards a call to an `Action<>` delegate with the first parameter set to the `object` type to an `Action<>` delegate with the concrete type of a class by casting the first argument. This is used to provide an event's `sender` as a concrete instance type to client code that handles the event. Instead of code generating each forwarding lambda, AutoFluent uses `DemoteSender()` to reduce the code size of the resulting AutoFluent class library.
