Latte supports

• Operator Binding
• DSL
• Data Class
• Pre-Processing define/undef
• Inner Method
• Lambda
• JSON Literal
• Read Eval Print Loop
• many other features

Latte is based on java 8. It's compiled to JVM byte code, and can collaborate with any java library.

#How to build

JRE 8 is the only thing required.

The project is managed by Maven, you can use Maven 3 to build automatically

clone the repository, and run

mvn clean package

You will get a runnable jar (repl.jar) and two shell scripts (latte and latte.bat). The shell scripts can help you run the repl.

run:

./latte

then the REPL starts

#Compile lt Files There are two ways of compiling lt files

• use program command

    latte -c <source-directory>
  

  the detailed commands and options can be found in

    latte -help
  

or:

• start the REPL interpreter, and construct a Compiler

    compiler = Compiler()
  

  use >> operator to specify output directory

    compiler >> '...'
    // or
    compiler >> File('...')
  

  use + operator to add class-path

    compiler + '...'
  

  use compile MAP to specify source codes to be compiled and start compiling

    compiler compile {'fileName':FileObject}
  

  usually filesInDirectory('...') is used, e.g.

    compiler compile filesInDirectory('...')
  

  these method invocations can be chained up

    Compiler() + '...cp...' >> '...output...' compile filesInDirectory('...source...')
  

  You can write a script to configure the settings. Check build.lts for more info.

#Scripts

• you can run a script directly

    latte -s script-location script-arguments...
  

or:

• start the REPL interpreter
  type :script <script file> and Enter

  then use script run or script run ['string array'] to run the script

Atom上的扩展插件:

atom-latte-lang-highlighting
atom-latte-lang-ide

Latte 支持如下功能

• 运算符绑定
• DSL
• Data Class
• 预处理 define/undef
• 内部方法
• Lambda
• JSON 字面量
• Read Eval Print Loop
• 许多其它特性

Latte基于java8。它被编译到JVM字节码，可以与任何Java类库完美互通。

#如何构建工程

环境仅仅需要 JRE 8

本工程使用 Maven 进行管理，所以您也可以使用 Maven 3 进行自动Build

clone这个仓库,然后执行

mvn clean package

你将会获取一个可执行jar (repl.jar) 以及两个shell脚本 (latte 和 latte.bat), shell脚本可以快捷地开启repl.

执行:

./latte

接着, REPL 将开始运行

#编译 lt 文件

• 使用程序命令

    latte -c <source-directory>
  

  详细的命令与选项可以这样找到

    latte -help
  

或者:

• 开启REPL, 然后构造一个Compiler

    compiler = Compiler()
  

  使用 >> 运算符来指定编译输出目录

    compiler >> '...'
    // or
    compiler >> File('...')
  

  使用 + 运算符来添加 class-path

    compiler + '...'
  

  使用 compile MAP 来确定源代码并立即开始编译

    compiler compile {'fileName':FileObject}
  

  通常来说会使用 filesInDirectory('...'), e.g.

    compiler compile filesInDirectory('/Users/me/src')
  

  这些方法调用可以被串联起来

    Compiler() + '...cp...' >> '...output...' compile filesInDirectory('...source...')
  

  您可以编写一个脚本 script 来配置这些属性。查看 build.lts 以获取更多信息。

#Scripts

• 你可以直接运行脚本

    latte -s script-file-path script-arguments...
  

或者：

• 开启 REPL 解释器
  输入 :script <script file> 并回车

  然后使用 script run 或者 script run ['string array'] 来运行这个脚本

#语法 您可以从这两个地方获取语法规则
