The Tu Programming Language

tu-lang(凸）是一种编程语言，旨在创造一种非常简单的零依赖、支持动态&&静态语法的编译型语言,全静态链接，目前已自举完成: compiler纯动态语法，asmer纯静态语法，linker动静混合语法.

tu  [options] file.tu        
    build *.tu              编译成汇编后进行链接生成二进制可执行文件
    -s  *.tu|dir            编译为tulang代码为linux-amd64汇编文件
    -c  *.s |dir            编译汇编为elf&pecoff跨平台可重定向cpu指令集文件
    -o  *.o |dir            链接elf&pecofff可重定向文件生成最终执行程序
    -d                      开启trace日志打印编译详细过程
    -gcc                    支持通过gcc链接生成最终可执行程序
    -g                      编译tu文件时带上debug段信息,支持栈回溯
    -std                    编译runtime&std相关内置库代码

async(无栈协程)

use fmt
use runtime
use os

mem ReadStream: async {
    i32 bytes
    i32 readn
    i32 fd
}
ReadStream::poll(){
    if this.readn != this.bytes {
	this.readn += 1
	return runtime.PollPending
    }	
    match this.fd {
	1 : return runtime.PollReady , "hello "
	2 : return runtime.PollReady , "world"
	_ : os.die("")
    }
}
async read(){
    fut<ReadStream> = new ReadStream  { fd: 1, bytes: 5 }
    buf += fut.await

    fut2<ReadStream> = new ReadStream { fd: 2, bytes: 5 }
    buf += fut2.await
    return buf
}

fn main(){
    body = runtime.block(read())
    fmt.println(body)
