Str

Str is an F# extension and module library for System.String It compiles to Javascript and Typescript with Fable.

It Includes:

• A Str module that has all methods from the String type as functions, and more. Adapted and extended from FSharpX

• A Computational Expressions str that can be used build up strings ( using a StringBuilder internally).

• Extension members on Str like .Get .First .Last .SecondLast and more. With nicer IndexOutOfRangeExceptions that include the bad index and the actual size.

• Extensive Tests running on both .NET and JS

Usage

Just open the module

open Str

this module contains: - a static class also called Str - a Computational Expressions called str - this will also auto open the extension members on System.String

then you can do:

let hello = // "Hello, World !!!"
    str {
        "Hello"
        ','
        " World "
        for i in 1..3 do
            "!"
    }
