Functions ¶
func CopyDir ¶
CopyDir copy files recursively from source to target directory.
The filter accepts a function that process the path info. and should return true for need to filter.
It returns error when error occurs in underlying functions.
func CopyDir1 ¶
*
- 拷贝文件夹,同时拷贝文件夹中的文件
- @param srcPath 需要拷贝的文件夹路径: D:/test
- @param destPath 拷贝到的位置: D:/backup/
func GetAllSubDirs ¶
GetAllSubDirs returns all subdirectories of given root path. Slice does not include given path itself.
func GetFileExist ¶
func GetFileListBySuffix ¶
GetFileListBySuffix returns an ordered list of file paths. It recognize if given path is a file, and don't do recursive find.
func GetMP4Duration ¶
GetMP4Duration 获取视频时长，以秒计
func GetSrcPath ¶
GetSrcPath returns app. source code path. It only works when you have src. folder in GOPATH, it returns error not able to locate source folder path.
func HomeDir ¶
HomeDir returns path of '~'(in Linux) on Windows, it returns error when the variable does not exist.
func HumaneFileSize ¶
HumaneFileSize calculates the file size and generate user-friendly string.
func IsDirOrCreate ¶
func IsExist ¶
IsExist checks whether a file or directory exists. It returns false when the file or directory does not exist.
func IsFile ¶
IsFile returns true if given path is a file, or returns false when it's a directory or does not exist.
func LgetAllSubDirs ¶
LgetAllSubDirs returns all subdirectories of given root path, including following symbolic links, if any. Slice does not include given path itself.
func LstatDir ¶
LstatDir gathers information of given directory by depth-first. It returns slice of file list, follows symbolic links and includes subdirectories if enabled; it returns error and nil slice when error occurs in underlying functions, or given path is not a directory or does not exist.
Slice does not include given path itself. If subdirectories is enabled, they will have suffix '/'.
func StatDir ¶
StatDir gathers information of given directory by depth-first. It returns slice of file list and includes subdirectories if enabled; it returns error and nil slice when error occurs in underlying functions, or given path is not a directory or does not exist.
Slice does not include given path itself. If subdirectories is enabled, they will have suffix '/'.
