Provides syntactic sugar for accessing settings that represent file system paths. For every tomo setting in the form :<name>_path, Paths will expose a method of that name that behaves like a Ruby Pathname object. As a special exception, the :deploy_to setting is also exposed even though it does not follow the same naming convention.

In tomo the following path settings are always available:

settings[:deploy_to]     # => "/var/www/my-app"
settings[:current_path]  # => "/var/www/my-app/current"
settings[:release_path]  # => "/var/www/my-app/releases/20190531164322"
settings[:releases_path] # => "/var/www/my-app/releases"
settings[:shared_path]   # => "/var/www/my-app/shared"

Using Paths, these same settings can be accessed like this:

paths.deploy_to # => "/var/www/my-app"
paths.current   # => "/var/www/my-app/current"
paths.release   # => "/var/www/my-app/releases/20190531164322"
paths.releases  # => "/var/www/my-app/releases"
paths.shared    # => "/var/www/my-app/shared"

More powerfully, the values returned by Paths respond to join and dirname, so you can easily compose them:

paths.current.dirname       # => "/var/www/my-app"
paths.release.join("tmp")   # => "/var/www/my-app/releases/20190531164322/tmp"
paths.shared.join("bundle") # => "/var/www/my-app/shared/bundle"

Paths can be used wherever a path string is expected, like chdir:

remote.chdir(paths.current) do"bundle", "exec", "puma", "--daemon")
# $ cd /var/www/my-app/current && bundle exec puma --daemon

If a plugin defines a setting with the suffix _path or if you create your own setting with that suffix, it automatically will be exposed via the Paths object:

# .tomo/config.rb
set my_custom_path: "/opt/custom"
paths.my_custom.join("var") # => "/opt/custom/var"
