# Introduction

It's a script language. I made it for quick developing.

It's in developing stage.

## Features

* Weak typing, interpreted script language.
* Easy rules.
* Bridge other languages library.
* The last user have power to change the library's behavior.
* ~~No `private` keyword, field and variable are public.~~

## Editor And Doc

**Editor**

Use **Atom** as editor.

[langX-atom](https://github.com/Aincvy/langX-atom.git) plugin, it's used for syntax highlighting, and it works in progress. And it do **not** support auto-complete.

**Document**

[langX in Gitbook](https://aincvy.gitbook.io/langx/)

## Simple code example

```
// a.lx
// this is the comment.

// this is the function.
funa => {
    a = 1 ;
    funb();

    // build-in function.
    println("funa" + a);
}

funb => {
  println("funb: " + a);
  a = 101 ;
}

// call function
funa();
```

```
// b.lx

// declare class
Student {

  // class member
  name;
  age = 20 ;

  // class function
  a => { print("hello,a!\n");}

  printInfo => (a3){ print("name: " + name + "\n");  print("age: " + age + "\n" ); print("a3: " + a3 + "\n");}

}

// new a object
s2 = new Student();
s1 = s2;

// set class prop
s1.age = 10 ;
s1.name = "Mr.Ming";
b = s2.age;
c = s2.name;
/*print("b: " + b + "\n");
//print("c: " + c + "\n");  */

s1.a();
s1.printInfo("ahahahah~");
```

## Compile and install

1. Please read section `Dependent` first.
2. Install `flex`,`bison`,`log4cpp`.
   1. Mac
      1. `brew install flex`
      2. `brew install bison`
      3. `brew install log4cpp`
   2. Debian
      1. Todo.
   3. Centos
      1. `yum install flex-devel bison-devel`
      2. Download and compile log4cpp.
3. Install `cmake`.
4. ```
   mkdir build && cd build
   cmake ..
   make
   sudo make install
   ```
5. Now, the simplest program is installed, you can use `langX --version` to test it.
6. You can try to compile mods now.
