Kuebiko

Kuebiko generates URLs from ruby code.

URLs generator class inherits Kuebiko::Url.

class ArticleUrl < Kuebiko::Url
  material :article
  scheme :http
  host "kaeruspoon.net"

  def show
    build "articles", article.title
  end
end

You can generate path or URL.

article.title #=> "first_day"

ArticleUrl.show_path(article) #=> "/articles/first_day"
ArticleUrl.show_url(article) #=> "http://kaeruspoon.net/articles/first_day"

url = ArticleUrl.new(article)
url.show_path #=> "/articles/first_day"
url.show_url #=> "http://kaeruspoon.net/articles/first_day"

Methods of suffix _path generate only path. Methods of suffix _url generate URL.

show instance method is called from show_path method (or show_url).

You can specify name of material. The material name will use as internal accessor name.

class ArticleUrl < Kuebiko::Url
  material :article

  def hoge
    build article.title # article is the internal accessor
  end
end

You can pass the material object to the initializer or generator class methods.

url = Article.new(article)
Article.show_path(article)

The internal accessor returns nil if you do not pass the material object.

You can specify more than one materials.

class ArticleUrl < Kuebiko::Url
  material :article, :user
end

The order in which you specify the materials will be the order of the objects to pass to the arguments.

url = ArticleUrl.new(article, user)

The name options is reserved as internal accessor.

You can specify default components.

Kuebiko.default_components(
  scheme: :https,
  host: "kaeruspoon.net", 
  port: 443
)

The default value of each components are following when you do not specify value.

• scheme :http
• host nil
• port nil

You can specify several options.

Kuebiko.default_components(
  host: "kaeruspoon.net",
  trailing_slash: true
)

Generating the URL with trailing slash if trailing_slash is true.

You can specify these components and options in Kuebiko::Url class.

class ArticleUrl < Kuebiko::Url
  scheme :http
  host "kaeruspoon.net"
  port 3000
  trailing_slash true

The value in Kuebiko::Url class overrides the value of Kuebiko.default_components.

You can specify these components and options at the build method.

class ArticleUrl < Kuebiko::Url
  def show
    build "articles", article.title, scheme: :https, host: "a.kaeruspoon.net", port: 1234, trailing_slash: true
  end
end

The value of build method overrides the value of Kuebiko::Url class.

The build method plays the central role to make up URLs. The first part of arguments would become the path of URL. The each arguments would be joined by slash.

class ArticleUrl < Kuebiko::Url
  def show
    build "articles", article.title
  end
end

"articles" and article.title would be joined by slash. The result is "articles/first_day" (article.title is "first_day"). The show_path method returns "/articles/first_day".

The second part of argument is components and options (see avobe). There are following options in addition to trailing_slash.

query is used to make up the query string.

build "articles", article.title, query: {special_code: 123}
 #=> "articles/first_day?special_code=123"

anchor is used to add the anchor to the URL.

build "articles", article.title, anchor: "top_navi"
  #=> "articles/first_day#top_navi"

There is options internal accessor.

class ArticleUrl < Kuebiko::Url
  material :article

  def show
    queries = options.select {|k,v| %i|code mode|.include?(k.to_sym) }
    build "articles", article.title, query: queries
  end
end

params = {controller: :articles, action: :index, code: "A", hoge: "B"}
url = Article.new(article, params)
url.show_path #=> "/articles/first_day?code=A"
Article.show_path(article, params) #=> "/articles/first_day?code=A"

The arguments after materials arguments become options.
