LanguageExt.Sys
LanguageExt.Sys
is the a wrapper around the System
namespace IO functions and is part of the language-ext functional programming framework.
The framework uses and abuses the features of C# to provide a pure functional-programming 'Base Class Library' that, if you squint, can look like extensions to the language itself. The desire here is to make programming in C# much more robust by helping the engineer's inertia flow in the direction of declarative and pure functional code rather than imperative.
Using these techniques for large code-bases can bring tangible benefits to long-term maintenance by removing hidden complexity and by easing the engineer's cognitive load.

Patch<EqA, A> |
Uses patch-theory to efficiently calculate the difference (Patch.diff(list1, list2) ) between two collections of A and build a patch which can be applied (Patch.apply(patch, list) ) to one to make the other (think git diff). |
Traits
The traits are major feature of v5
+ language-ext that makes generic programming with higher-kinds a reality. Check out Paul's series on Higher Kinds to get a deeper insight.
Value traits
These work a little like NewType
but they impart semantic meaning and some common operators for the underlying value.
Location | Feature | Description |
---|---|---|
Core |
DomainType<SELF, REPR> |
Provides a mapping from SELF to an underlying representation: REPR |
Core |
Identifier <SELF> |
Identifiers (like IDs in databases: PersonId for example), they are equivalent to DomaintType with equality. |
Core |
VectorSpace<SELF, SCALAR> |
Scalable values; can add and subtract self, but can only multiply and divide by a scalar. Can also negate. |
Core |
Amount <SELF, SCALAR> |
Quantities, such as the amount of money in USD on a bank account or a file size in bytes. Derives VectorSpace , IdentifierLike , DomainType , and is orderable (comparable). |
Core |
LocusLike <SELF, SCALAR, DISTANCE> |
Works with space-like structures. Spaces have absolute and relative distances. Has an origin/zero point and derives DomainType , IdentifierLike , AmountLike and VectorSpace . DISTANCE must also be an AmountLike<SELF, REPR, SCALAR> . |

Echo.Process
echo-process Actor library component that works with LanguageExt.Core: An 'Erlang like' process system (actors) that can optionally persist messages and state to Redis (note you can use it without Redis for in-app messaging). The process system additionally supports Rx streams of messages and state allowing for a complete system of reactive events and message dispatch. |
