Covariant Script 编程语言解释器

欢迎使用Covariant Script编程语言!
Covariant Script是一种开源的跨平台编程语言
此项目为官方维护的Covariant Script解释器

切换语言

特点

  • 全平台可用,支持大多数主流操作系统
    • 使用 C++ 14 标准编写,支持版本较老的编译器
    • Apple macOS: Universal binary with x86_64 and arm64
    • Linux and Unix: x86, ARM, MIPS, LoongArch
    • Microsoft Windows: x86
  • 强大易用的扩展系统
    • C/C++ Native Interface(CNI) 系统:能够翻译 C/C++ 和 Covariant Script 之间的双向调用
    • Interpreter Bootstrap:在 C++ 项目中集成 Covariant Script 运行时环境的帮手
    • CNI 组成宏:将扩展系统与CNI系统有机结合,现已纳入语言标准
    • CFFI 支持: 直接调用使用 C 语言编写的动态库中的函数
  • 自研高效编译系统
    • 针对中文优化的 Unicode 支持
    • 无依赖、高效的编译器前端
    • 支持编译期优化
    • 可导出编译结果
  • 高性能运行时环境
    • 堆栈式非对称协程
    • 热点分析优化算法
    • 高效的内存管理系统
    • 引用计数垃圾回收器

安装

运行

解释器

cs [选项...] <文件|STDIN> [参数...]
cs [选项...]

当将 文件 换成 STDIN 时,解释器会直接从标准输入流读取

选项

解释器
选项 助记符 功能
--compile-only -c 仅编译
--dump-ast -d 导出高级语法树
--dependency -r 导出模块依赖
--csym <文件> -g <文件> 从文件中读取 cSYM 信息
交互式解释器(Repl)
选项 助记符 功能
--silent -s 关闭命令提示符
--args <...> -a <...> 设置程序参数

注意,在选项 --args 或其助记符 -a 之后设置的每一项都将被视为参数

通用选项
选项 助记符 功能
--no-optimize -o 禁用优化器
--help -h 显示帮助信息
--version -v 显示版本信息
--wait-before-exit -w 等待进程退出
--stack-resize <大小> -S <大小> 重设运行时栈大小
--log-path <路径> -l <路径> 设置日志输出路径
--import-path <路径> -i <路径> 设置引入查找路径

默认栈大小为1000,当设置的栈大小大于默认值时,协程的栈大小会动态调整为设置大小的十分之一;当堆栈大小设置小于默认值时,协程的堆栈大小将保持在100

注意,若不设置日志输出路径,将直接输出至标准输出流

调试器

cs_dbg [选项...] <文件>

选项

选项 助记符 功能
--help -h 显示帮助信息
--version -v 显示版本信息
--silent -s 关闭命令提示符
--wait-before-exit -w 等待进程退出
--csym <文件> -g <文件> 从文件中读取 cSYM 信息
--stack-resize <大小> -S <大小> 重设运行时栈大小
--log-path <路径> -l <路径> 设置日志路径
--import-path <路径> -i <路径> 设置引入查找路径

栈大小策略与解释器相同

若不设置日志路径,将直接输出至标准输出流
