goos

Usage

local goos = require("goos")

-- stat
local stat, err = goos.stat("./filename")
if err then error(err) end
print(stat.is_dir)
print(stat.size)
print(stat.mod_time)
print(stat.mode)

-- hostname
local hostname, err = goos.hostname()
if err then error(err) end
print(hostname)

-- get_pagesize
local page_size = goos.get_pagesize()
if not(page_size > 0) then error("bad pagesize") end

-- mkdir_all
goos.mkdir_all("./test/test_dir/test_dir/all")
local stat, err = goos.stat("./test/test_dir/test_dir/all")
if err then error(err) end

Functions

func Getpagesize

func Getpagesize(L *lua.LState) int

Getpagesize lua goos.pagesize() return number

Example

goos.get_pagesize()

state := lua.NewState()
Preload(state)
inspect.Preload(state)
source := `
local goos = require("goos")
local page_size = goos.get_pagesize()
print(page_size > 0)
	`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

true

func Hostname

func Hostname(L *lua.LState) int

Hostname lua goos.hostname() returns (string, error)

Example

goos.hostname()

state := lua.NewState()
Preload(state)
inspect.Preload(state)
source := `
local goos = require("goos")
local hostname, err = goos.hostname()
if err then error(err) end
print(hostname > "")
	`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

true

func Loader

func Loader(L *lua.LState) int

Loader is the module loader function.

func MkdirAll

func MkdirAll(L *lua.LState) int

MkdirAll lua goos.mkdir_all() return err

Example

goos.mkdir_all()

state := lua.NewState()
Preload(state)
inspect.Preload(state)
source := `
local goos = require("goos")
local err = goos.mkdir_all("./test/test_dir_example/test_dir")
if err then error(err) end
local _, err = goos.stat("./test/test_dir_example/test_dir")
print(err == nil)
	`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

true

func Preload

func Preload(L *lua.LState)

Preload adds goos to the given Lua state's package.preload table. After it has been preloaded, it can be loaded using require:

local goos = require("goos")

func Stat

func Stat(L *lua.LState) int

Stat lua goos.stat(filename) returns (table, err)

Example

goos.stat(filename)

state := lua.NewState()
Preload(state)
inspect.Preload(state)
source := `
local goos = require("goos")
local inspect = require("inspect")

local info, err = goos.stat("./test/test.file")
if err then error(err) end
info.mode=""
info.mod_time=0
print(inspect(info, {newline="", indent=""}))
`
if err := state.DoString(source); err != nil {
	log.Fatal(err.Error())
}

Output:

{is_dir = false,mod_time = 0,mode = "",size = 0}
