dir_walker

The Dir::Walker module supports the top-down traversal of a set of directories. It is similar to the standard method Dir.glob("**/*"), but has additional features like skip specific subdirectories, change the sort-oder of directory-listing (default: by name) or optionally ignore errors (IO::Error).

The sourcecode is a port of the Ruby standard lib Find.

The feature generally is also available in many other languages. Examples are:

* Find.find(...)       # Ruby
* os.walk(...)         # Python
* File::Find.find(...) # Perl
* filepath.Walk(...)   # Go

Installation

1. Add the dependency to your shard.yml:

dependencies:
  dir_walker:
    github: 4ndyfix/dir_walker

2. Run shards install

Usage

For example, to total the size of all files under your home directory, ignoring anything in a "dot" directory (e.g. $HOME/.ssh):

require "dir_walker"
  
total_size : Int64 = 0
  
Dir::Walker.walk(ENV["HOME"]) do |path|
  if File.directory? path
    if File.basename(path).starts_with?(".")
      Dir::Walker.prune_path # Don't look any further into this directory.
    end
  else
    total_size += File.size(path)
  end
end
  
puts total_size.humanize
