Script language engine for .NET programs

ReoScript is a powerful JavaScript-like script language engine for .NET Applications. It was designed for inclusion in applications that require a built-in, easy to use, scalable script language with no dependencies other language like C/C++.

• Fully JavaScript statements and operators implement
• JSON and Array literals
• Fully prototype chain mechanism
• Lambda Expression
• Enhanced Array Enumerator and Collection Operations
• Console Runner
• Data exchange with .Net CLR
• Property Extension and Function Extension
• Directly access .Net object with DirectAccess
• Import and using .Net Types in script
• Auto CLR Event Binding

ReoScript is not completely compliant to JavaScript/ECMAScript standard, it has stricter syntax check and own additional syntax, functions and objects in order to enhance usability of data exchange.

ReoScript provides a simple script Editor it can be used to write and execute script directly. The Editor can also be included in application and provided to end-user.

1. Download or build the following DLLs, add references to target project

    Antlr3.Runtime.dll
    unvell.ReoScript.dll
   

2. Import the following namespace

    using unvell.ReoScript;
   

3. Create ScriptRunningMachine and run script

    ScriptRunningMachine srm = new ScriptRunningMachine();
    srm.Run("alert('hello world!');");
   

   (semicolons at end of line in ReoScript are required)

This feature is planned to implement in next release.

function A() {
  this.a = 10;
}

function B() : A() {
  this.b = 20;
}

var b = new B;
console.log(b.a + b.a);

The output is:

30

Lambda based where, sum, min, max and etc. are available in Array operations.

var arr = [1, 5, 7, 8, 10, 13, 20, 24, 26];
var result = arr.where(n => n < 10).sum();

The result is:

21

function check_alive(user) {
    if (...) {
        return 'ok';
    } else {
        setTimeout(check_alive, 1000, user);
    }
}

var user = getCurrentUser();
setTimeout(check_alive, 1000, user);

common.rs:

function check_login(usr, pwd) {
    return (usr.password == hashed(pwd));
}

login.rs:

import "common.rs";

var usr = getCurrentUser();
check_login(usr, getInputtedPwd());

Supported to access .NET objects directly (DirectAccess mode).

Initializer used to simplify the code by merging construction and property setting:

var newApple = new Apple() {
    color : 'red',
};

It is same as:

var newApple = new Apple();
newApple.color = 'red';

var num = 0b1010;
console.log(num);

The output is:
