    internal DSL:

       Write your own  API libraries

       LISP, higher level abstraction for your program, bottom-up programming, " When youwork bottom-up, you usually end up with a different program.Instead of a single, monolithic program,you will get a larger language with more abstract operators, and a smaller program written in it. Instead of a lintel,you'll get an arch."

       GCI library?  webapp framework?




    external DSL:

    Used for:

       code generation

       Interpretation?  read and run

       configuration language




    Examples:

      makefile

      YACC, LEX

       RE

       graphviz .dot file

       SWIG  config file

         doubango bindings, some other programs' bindings generation

         

    ragel state machine compiler: 

         HTTP parser for mongrel

        doubango tinyDEMO config


    vlc stream configuration, VLM config

  • 神奇的LISP语言

    2014-11-23 11:52:32

    原文:http://www.paulgraham.com/diff.html


    1. 条件逻辑结构

    所谓条件逻辑结构即 if-then-else,这是McCarthy在开发LISP的时候发明的;今天几乎所有我们能看到的编和语言都包含这个结构,我们会觉得理所当然,而在那个年代Fortran只有GOTO。

    2. 函数数据类型

    函数作为一种数据类型像int,string一样,并可作为参数传递。

    3. 递归

    LISP是第一种支持递归的语言

    4. 变量是一种数据类型

    变量可以指向不同的数据类型,但作为变量他们都是同一种数据类型,你可以理解为指针概念的第一次出现。

    5. 垃圾清理

    C++,好吧

    6.
