REPL for ExprSharp

• Author: Stardust D.L.
• Version: 0.1

The REPL environment for ExprSharp.

ExprSharp: A tiny code language based on iExpr.Core.

For more information about ExprSharp, please see Wiki

Install

1. Install .Net Core Here
2. Download the repl tools Here
3. Unzip and get into the diretory, then use the command:

dotnet esi.dll

4. Enjoy it.
   • How to write codes in ExprSharp? see Wiki For ExprSharp

Examples

For example, you can write math expression:

1+2
2**20
math.pi

Or if you want to calculate 20! , you can write:

func{f=(n)=>func{if(n==0){return 1}{return n*f(n-1)}},return f(20)}

Or "paint" a triangle:

for(i=1;i<=21;i+=2){print(" "*((21-i)/2)+"*"*i+" "*((21-i)/2))}

Also you can make the Fibonacci numbers by iterator:

• In command line, it's so long in one line:

func{it=iter{this.current=0,f0:=0,f1:=1,this.next=(_)=>func{this.current=f0+f1,f0=f1,f1=this.current,return this.current<100}},print(list(it))}

• But in a file, it can be clear:
  • you just need to use command now to set the file name, and use run to run the file.

func{
    it=iter{
        this.current=0,
        f0:=0,
        f1:=1,
        this.next=(_)=>func{
            this.current=f0+f1,
            f0=f1,
            f1=this.current,
            return this.current<100
        }
    },
    print(list(it))
}
