goreader

A utility library to do files/io/bytes processing/parsing in file-system or network.

  1. These features are really common to be implemented for a non-server/local-running application. Though looking fairly easy, almost all had edge cases to be taken care of minutely.
  2. To use a library package instead of custom segments saves redundant testing/debugging.

Feature list

  • generate parse tree for given paths
    • list out files/folders separately
    • Get hidden files/folders separately
    • Preserve nested order for dir and files
    • Control recursion level
    • Pass custom functions to filter out files and dirs
    • Include StdIn if valid
  • Encodings
    • json to
      • file
      • yaml
    • yaml to
      • json
      • file
    • file to
      • json
      • yaml
  • IO ops
    • copy multi files to single one
    • clone file
    • Pass a callback to be executed over each line of a file
    • bash dirname & basedir function

How to use

use lister

tree := list.Read(&[]string{"."}, 2)
//tree.SkipHiddenDirs = true
e := tree.UpdateFiles()
tree.UpdateStdinStatus()

if e != nil {
    log.Fatal(e)
}
log.Println(tree.IsNestedDir)

use reader

for _,path := range tree.FilePaths{
	if strings.HasSuffix(path,"html") || strings.HasSuffix(path,"htm"){
		err := reader.CloneFile(path, path+".bak")
		if err != nil {
			fmt.Println(err)
			return
		}
		err = reader.CopyContent(path, "envoy/css.ht", path+".bak")
		if err != nil {
			fmt.Println(err)
			return
		}
		err = os.Remove(path+".bak")
		if err != nil {
			fmt.Println(err)
			return
		}
	}
}
