dir-util is just a collection of simple and useful utility methods for operating on directories on the filesystem.
dir-util depends on
fileutils being available. In test, it relies on rspec and either rcov (Ruby 1.8) or simplecov (Ruby 1.9).
Install the gem:
gem install dir-util-(version).gem
Running the tests:
Building the gem:
Install gem with Rake:
I've found that I often want to do something to every file contained in a directory tree (ie, in the directory and all its subdirectories, all the way down until all the subdirectories are exhausted).
For example, I recently wrote a program that went through a directory and found all the image files, processed them, and moved them out to another location.
DirUtil.to_all_files("~/Documents") do |filename| puts filename end
The block is passed recursively to every subdirectory.
The way I think about the naming for this one is "to all files do ".
Sometimes you just want to know all the subdirectories under a directory.
DirUtil.subdirectories("~") == ["/Users/sirsean/Documents", "/Users/sirsean/Desktop", "/Users/sirsean/Documents/sub1", "/Users/sirsean/Desktop/sub2"]
The list you get back is ordered such that all the top-level subdirectories come first; basically, if you wanted to delete all the subdirectories, you'd want to reverse the list first.
