Find

The +Find+ module supports the top-down traversal of a set of file paths.

Installation

Add this line to your application's Gemfile:

gem'find'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install find

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'find'total_size=0Find.find(ENV["HOME"])do |path|
ifFileTest.directory?(path)ifFile.basename(path).start_with?('.')Find.prune# Don't look any further into this directory.elsenextendelsetotal_size += FileTest.size(path)endend

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
