Overview

Package pathKit

@Author Richelieu @Description 主要是对"path"、"path/filepath"的封装.

PS: filepath标准库的使用可以参考: https://www.cnblogs.com/jkko123/p/6923962.html

var GetOsTempDir func() string = os.TempDir

GetOsTempDir 获取系统的临时目录.

PS: 不建议向系统临时目录中放东西(服务器不一定会给权限).

e.g.

Windows	"C:\Users\Lenovo\AppData\Local\Temp"
Mac		"/var/folders/4_/33p_vn057msfh2nvgx6hwv_40000gn/T/"

var ReadDir func(name string) ([]os.DirEntry, error) = os.ReadDir

ReadDir 遍历目录.

PS: (1) 有子目录的话,"不会" 继续遍历; (2) "不会" 遍历到到传参name目录; (3) 例子可以参考 notes/Golang/Golang.wps.

View Source
var Walk func(root string, fn filepath.WalkFunc) error = filepath.Walk

Walk 遍历目录.

Deprecated: Use WalkDir instead.

PS: (1) 遍历包含 传参root; (2) filepath.Walk 和 filepath.WalkDir 的区别:

(a) filepath.WalkDir 是在 Go1.16 中引入的,比 filepath.Walk 更高效,filepath.WalkDir 避免了对每个访问的文件或目录调用 os.Lstat
(b) 回调函数fn的传参不同,分别为 filepath.WalkFunc 和 fs.WalkDirFunc,
	此外,WalkDirFunc 在读取目录之前调用,以允许 SkipDir 完全跳过目录读取。如果目录读取失败,则该函数会再次为该目录调用一次以报告错误.

var WalkDir func(root string, fn fs.WalkDirFunc) error = filepath.WalkDir

WalkDir 遍历目录.

PS: (1) 有子目录的话,"会" 继续遍历; (2) "会" 遍历到到传参root目录; (3) 例子可以参考 notes/Golang/Golang.wps.

Functions

func ChangeWorkingDir

func ChangeWorkingDir(dir string) error

ChangeWorkingDir 使用给定的路径,更改当前的工作路径.

func CheckSkip

func CheckSkip(parent, path string) bool

CheckSkip 检查是否发生"路径穿越"(路径穿透)

@param path 父路径 @param path1 子路径 @return true: 发生"路径穿越"

e.g. ("/a//b/", "/a//b//../c.docx") => true ("/a//b/", "//a//b///c.docx") => false

func ExpandTilde

func ExpandTilde(path string) (string, error)

ExpandTilde 拓展路径中的"~"("~"(波浪号) => 当前用户主目录).

e.g. ("") => "", nil ("~") => "/Users/richelieu", nil ("~/a/b/c") => "/Users/richelieu/a/b/c", nil

func FromSlash

func FromSlash(path string) string

FromSlash 将路径中的"/"替换为路径分隔符

func GetExclusiveTempDir

func GetExclusiveTempDir() (string, error)

GetExclusiveTempDir 获取 本依赖 的专属临时目录.

PS: 不建议向系统临时目录中放东西(服务器不一定会给权限).

e.g. macOS
() => "/var/folders/4_/33p_vn057msfh2nvgx6hwv_40000gn/T/$$chimera/cmnmk1pus0n0snnatg40 <nil>", nil

func GetHomeDir

func GetHomeDir() string

GetHomeDir 获取当前用户的home dir(当前用户主目录)

func GetTempDir

func GetTempDir() string

GetTempDir 获取 项目 的临时目录.

func GetWorkingDir

func GetWorkingDir() string

GetWorkingDir 获取 当前工作目录的绝对路径

func Join

func Join(eles ...string) string

Join 将多个字符串合并为一个路径(路径拼接).

PS: (1) 不建议用"path.Join",有问题,e.g. 传参:"d:\\nacos\\", "cyy" (2) 此方法也可用于优化路径(处理: 路径穿越、多个连续的路径分隔符...).

e.g. () => "" ("") => "" ("", "") => "" ("", "a") => "a"

(".", "yozo.eio") => "yozo.eio"

(" ") => " " (" ", "a") => " /a"

e.g.1 支持: 路径穿越(路径穿透) ("/a/b", "../c.docx") => "/a/c.docx"

func ReviseWorkingDirInTestMode

func ReviseWorkingDirInTestMode(projectName string) (string, error)

ReviseWorkingDirInTestMode 适用于: 测试模式(_test.go)

@return 修改后的WorkingDir + error

func SetTempDir

func SetTempDir(dirPath string) error

func Split

func Split(path string) (dir, file string)

Split 分割路径中的目录与文件.

e.g. Mac ("/Users/richelieu/Downloads/") => "/Users/richelieu/Downloads/", "" ("/Users/richelieu/Downloads") => "/Users/richelieu/", "Downloads"

func SplitList

func SplitList(path string) []string

SplitList 使用"路径列表分隔符"将路径分开.

os.PathListSeparator(linux下默认为':',windows下为';')

e.g. ("d:/a/b/c.docx") => [d:/a/b/c.docx] ("C:/windows;C:/windows/system") => [C:/windows C:/windows/system]

func ToSlash

func ToSlash(path string) string

ToSlash 将路径分隔符使用"/"替换
