目录扫描

ScanDir

说明：扫描指定目录，可扫描文件或目录，支持递归扫描。
格式:

func ScanDir(path string, pattern string, recursive ...bool) ([]string, error)

示例：

func ExampleScanDir() {
	// init
	var (
		fileName = "gflie_example.txt"
		tempDir  = gfile.TempDir("gfile_example_scan_dir")
		tempFile = gfile.Join(tempDir, fileName)
		tempSubDir  = gfile.Join(tempDir, "sub_dir")
		tempSubFile = gfile.Join(tempSubDir, fileName)
	)
	// write contents
	gfile.PutContents(tempFile, "goframe example content")
	gfile.PutContents(tempSubFile, "goframe example content")
	// scans directory recursively
	list, _ := gfile.ScanDir(tempDir, "*", true)
	for _, v := range list {
		fmt.Println(gfile.Basename(v))
	}
	// Output:
	// gflie_example.txt
	// sub_dir
	// gflie_example.txt
}

ScanDirFile

说明：扫描指定目录的文件，支持递归扫描
格式:

func ScanDirFile(path string, pattern string, recursive ...bool) ([]string, error)

示例：

func ExampleScanDirFile() {
	// init
	var (
		fileName = "gflie_example.txt"
		tempDir  = gfile.TempDir("gfile_example_scan_dir_file")
		tempFile = gfile.Join(tempDir, fileName)
		tempSubDir  = gfile.Join(tempDir, "sub_dir")
		tempSubFile = gfile.Join(tempSubDir, fileName)
	)
	// write contents
	gfile.PutContents(tempFile, "goframe example content")
	gfile.PutContents(tempSubFile, "goframe example content")
	// scans directory recursively exclusive of directories
	list, _ := gfile.ScanDirFile(tempDir, "*.txt", true)
	for _, v := range list {
		fmt.Println(gfile.Basename(v))
	}
	// Output:
	// gflie_example.txt
	// gflie_example.txt
}

ScanDirFunc

说明：扫描指定目录（自定义过滤方法），可扫描文件或目录，支持递归扫描
格式:

func ScanDirFunc(path string, pattern string, recursive bool, handler func(path string) string) ([]string, error)

示例：

func ExampleScanDirFunc() {
	// init
	var (
		fileName = "gflie_example.txt"
		tempDir  = gfile.TempDir("gfile_example_scan_dir_func")
		tempFile = gfile.Join(tempDir, fileName)
		tempSubDir  = gfile.Join(tempDir, "sub_dir")
		tempSubFile = gfile.Join(tempSubDir, fileName)
	)
	// write contents
	gfile.PutContents(tempFile, "goframe example content")
	gfile.PutContents(tempSubFile, "goframe example content")
	// scans directory recursively
	list, _ := gfile.ScanDirFunc(tempDir, "*", true, func(path string) string {
		// ignores some files
		if gfile.Basename(path) == "gflie_example.txt" {
			return ""
		}
		return path
	})
	for _, v := range list {
		fmt.Println(gfile.Basename(v))
	}
	// Output:
	// sub_dir
}

ScanDirFileFunc

说明：扫描指定目录的文件（自定义过滤方法），支持递归扫描。
格式:

func ScanDirFileFunc(path string, pattern string, recursive bool, handler func(path string) string) ([]string, error)

示例：

func ExampleScanDirFileFunc() {
	// init
	var (
		fileName = "gflie_example.txt"
		tempDir  = gfile.TempDir("gfile_example_scan_dir_file_func")
		tempFile = gfile.Join(tempDir, fileName)
		fileName1 = "gflie_example_ignores.txt"
		tempFile1 = gfile.Join(tempDir, fileName1)
		tempSubDir  = gfile.Join(tempDir, "sub_dir")
		tempSubFile = gfile.Join(tempSubDir, fileName)
	)
	// write contents
	gfile.PutContents(tempFile, "goframe example content")
	gfile.PutContents(tempFile1, "goframe example content")
	gfile.PutContents(tempSubFile, "goframe example content")
	// scans directory recursively exclusive of directories
	list, _ := gfile.ScanDirFileFunc(tempDir, "*.txt", true, func(path string) string {
		// ignores some files
		if gfile.Basename(path) == "gflie_example_ignores.txt" {
			return ""
		}
		return path
	})
	for _, v := range list {
		fmt.Println(gfile.Basename(v))
	}
	// Output:
	// gflie_example.txt
	// gflie_example.txt
}
