The class Iri
helps you build a URI and then modify its
parts via a simple fluent interface:
require 'iri'
url = Iri.new('http://google.com/')
.append('find').append('me') # -> http://google.com/find/me
.add(q: 'books about OOP', limit: 50) # -> ?q=books+about+OOP&limit=50
.del(:q) # remove this query parameter
.del('limit') # remove this one too
.over(q: 'books about tennis', limit: 10) # replace these params
.scheme('https') # replace 'http' with 'https'
.host('localhost') # replace the host name
.port('443') # replace the port
.fragment('page-4') # replaces the fragment part of the URI, after the '#'
.query('a=1&b=2') # replaces the entire query part of the URI
.path('/new/path') # replace the path of the URI, leaving the query untouched
.cut('/q') # replace everything after the host and port
.to_s # convert it to a stringThe full list of methods is here.
Install it:
$ gem install iriOr add this to your Gemfile:
gem 'iri'Pay attention, it is not a parser. The only functionality this gem provides is building URIs.
It is very convenient to use inside HAML, for example:
- iri = Iri.new(request.url)
%a{href: iri.over(offset: offset + 10)} Next Page
%a{href: iri.over(offset: offset - 10)} Previous PageOf course, it's better to create the iri object only once per request
and re-use it where you need. It's immutable, so you won't have any
side-effects.
PS. See how I use it in this Sinatra web app: yegor256/0rsk.
