内置基础函数库 都是lua接口
- v = vela.args(0)
- 获取命令行参数
- vela.copy.run(dst , src)
- vela.copy.spawn(dst , src) 异步
- chl = vela.channel(10)
- vela.catch(a , b , c , d)
- 捕获错误是否为空
锁服务，提供rwmutex 和 mutx
local mu = sync.mutex
mu.lock()
mu.unlock()
local rw = sync.rwmutex
rw.lock()
rw.unlock()
rw.read()
rw.unread()wait group接口
local wg = sync.wait_group(100)
wg.add(100)
wg.done(1)
wg.wait()原子操作
local a = atomic(10)
a.add(1)
a.sub(10)
print(a.value)
-- time.now 处理接口
print(time.now("mil") ) -- "2006-01-02 15:04:05.00"
print(time.now("sec") ) -- "2006-01-02 15:04:05"
print(time.now("min") ) -- "2006-01-02 15:04"
print(time.now("hour")) -- "2006-01-02.15"
print(time.now("day") ) -- "2006-01-02"
print(time.now("mon") ) -- "2006-01"
print(time.now("year")) -- "2006"
print(time.now("2006-01-02.15.05.05.00")) -- "2022-02-22.18.13.11.33"
local now = time.now()
print(now.sec) --59
print(now.min) --59
print(now.hour) --23
print(now.day) --30
print(now.week) --sunday
print(now.month) -- 12
print(now.year) -- 2022
print(now.tt_sec) --秒级别时间戳
print(now.tt_milli) --毫秒级别时间戳
print(now.tt_nano) --纳秒级别时间戳
print(now.today) -- 2022-02-22
print(now.format("2006-01-02")) -- 2022-02-22- 控制台输出 支持lua.writer
local out = std.out
out.println(1111)
out.print("helo")
local err = std.err
err.println("sss")
err.print("helo error")- 条件控制
- cond = vela.regex(v1 , v2 , v2 , ...)
- cond = vela.equal(v1 , v2 , v2 , ...)

local cond = vela.suffix("abcc-aa" ,"abc" , "abaa") -- true
local cond = vela.grep("abcccc" , "ab*" , "acc*") -- true
--todo
cond.Y(function(a) print(a) end, "y") --y
cond.Y(function() print("x") end) --x
cond.Y().N()
格式化字符串
print(F("%s %d %v" , "helo" , 10 , userdata))
-- 系统底层会默认调用String() 格式化对象
