A simple class to handle conditional logic of looking for a file in multiple paths.
Add this line to your application's Gemfile:
gem 'path_to'And then execute:
$ bundle
Or install it yourself as:
$ gem install path_to
Not unlike a $PATH environment variables, a PathTo instance contains one
or more locations to look for a file, and will return the first file it finds.
Example:
Suppose you have some files in the following directory structure:
├── default_files
│ └── alpha
│ └── bravo
├── specific_files
│ └── alpha
Then you can use path_to to add specific_files and default_files to the
locations to look for your files.
require 'path_to'
p = PathTo.new('specific_files', 'default_files')
p.path_to 'alpha'
# => 'specific_files/alpha'
p.path_to 'bravo'
# => 'default_files/bravo'And there is a shortcut for returning File objects.
p.file('alpha')
# => #<File:specific_files/alpha> After checking out the repo, run bin/setup to install dependencies. Then, 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 to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
