引用的开源库

ANTLR

项目地址:https://github.com/antlr/antlr4

引用版本:4.7.2

开源许可证:BSD 3-clause license

备注:除了安装Antlr4运行程序,还需要安装其中的C++运行时库。

LLVM

项目地址:https://github.com/llvm/llvm-project

引用版本:9.0.1

开源许可证:Apache License Version 2.0

备注:主要使用了静态版本,Linux下可以通过包管理器直接安装LLVM-9。

语法设计说明

以易语言语法为蓝本,扩充了一些关键字和语法特性。

目标和愿景

  • 快速原型开发和算法验证;

  • 非编程专业人士也能轻松开发软件;

  • 设计即产品(Design as a Product)。

项目现状

  • 由于忙于为供职的公司做开发,可能不会在本项目上稳定输出;

  • 完成对编译系统框架的搭建;

  • 完成了基础语法文件;

  • 完成了从编译到最终可执行程序生成的主流程;

  • 实现了部分字符串和数组的运行时静态库;

  • 实现了支持断点和单步的调试信息。
