Dynamic Method Handling

This class handles dynamic methods through the method_missing method in the class Hanami::Utils::String

Instance Method Details

#join(*strings) ⇒ Hanami::Utils::PathPrefix

Joins self with the given token. It cleans up all the separator repetitions.

Examples:

Single string

require 'hanami/utils/path_prefix'

path_prefix = Hanami::Utils::PathPrefix.new('/posts')
path_prefix.join('new').to_s  # => "/posts/new"
path_prefix.join('/new').to_s # => "/posts/new"

path_prefix = Hanami::Utils::PathPrefix.new('posts')
path_prefix.join('new').to_s  # => "/posts/new"
path_prefix.join('/new').to_s # => "/posts/new"

Multiple strings

require 'hanami/utils/path_prefix'

path_prefix = Hanami::Utils::PathPrefix.new('myapp')
path_prefix.join('/assets', 'application.js').to_s
  # => "/myapp/assets/application.js"

Parameters:

  • strings (::String) —

    the token(s) we want to join

Returns:

  relative_join(strings).absolute!
end

#relative_join(strings, separator = @separator) ⇒ Hanami::Utils::PathPrefix

Joins self with the given token, without prefixing it with separator. It cleans up all the separator repetitions.

Examples:

require 'hanami/utils/path_prefix'

path_prefix = Hanami::Utils::PathPrefix.new 'posts'
path_prefix.relative_join('new').to_s      # => 'posts/new'
path_prefix.relative_join('new', '_').to_s # => 'posts_new'

Parameters:

  • strings (::String) —

    the tokens we want to join

  • separator (::String) (defaults to: @separator) —

    the separator used between tokens

Returns:

Raises:

  • (TypeError) —

    if one of the argument can’t be treated as a string

Since:

  • 0.1.0
