MoreLINQ

LINQ to Objects is missing a few desirable features.

This project enhances LINQ to Objects with extra methods, in a manner which keeps to the spirit of LINQ.

MoreLINQ is available for download and installation as NuGet packages.

Documentation for the stable and beta releases can be found at morelinq.github.io.

Usage

MoreLINQ can be used in one of two ways. The simplest is to just import the MoreLinq namespace and all extension methods become instantly available for you to use on the types they extend (typically some instantiation of IEnumerable<T>). In some very rare instances, however, doing so can cause conflicts with other libraries you may be using that incidentally also extend the same type with an identically named method and signature. This happened with MoreLINQ, for example, when Microsoft .NET Framework 4.0 introduced Zip and MoreLINQ already had one. Starting with version 3.0 of MoreLINQ, you can reduce the potential for present (or even future) conflicts by individually importing just the extension methods you need using the static imports feature introduced in C# 6:

using static MoreLinq.Extensions.LagExtension;
using static MoreLinq.Extensions.LeadExtension;

In the example above, only the Lag and Lead extension methods will be available in scope.

Apart from extension methods, MoreLINQ also offers regular static method that generate (instead of operating on) sequences, like Unfold, Random, Sequence and others. If you want to use these while statically importing other individual extension methods, you can do so via aliasing:

using static MoreLinq.Extensions.LagExtension;
using static MoreLinq.Extensions.LeadExtension;
using MoreEnumerable = MoreLinq.MoreEnumerable;

In the example above, Lag and Lead will be available as extension methods as well as all the regular static methods on MoreEnumerable but without any of the extension methods offered by MoreEnumerable.

Building

Run either build.cmd if building on Windows or build.sh if building on macOS or a Linux distribution supported by .NET.

Some code in the project is generated using T4 templates. To regenerate the code from modified templates, run MoreLinq\tt.cmd (Windows) or MoreLinq/tt.sh depending on your platform.

Building the documentation is supported on Windows only and requires Sandcastle Help File Builder (SHFB). Executing builddocs.cmd generates the documentation in the docs/api directory. It can be browsed locally using any HTTP server of static files, like dotnet-serve.
