Irwi

Irwi is a Ruby on Rails 4 plugin which adds wiki functionality to your application.

Status

Build Status

Installation

Add to your Gemfile:

gem 'irwi', :git => 'git://github.com/alno/irwi.git'

Then in your application directory call:

rails g irwi_wiki

It will generate:

  • WikiPageController to serve wiki pages
  • WikiPage model to represent page
  • Migration to prepare database

Also it will add to your routes.rb something like:

wiki_root '/wiki'

Wiki syntax (links to other pages)

You can link pages by using

[[Some page title]]

construction in text. If linked page exists, when it will be replaced with link to this page, in other case it will be replaced with link to new page with such path/title.

Template definition

You may create your own templates for controller actions (show, edit and history), in other case default built-in templates will be used.

Helper definition

Following helpers are defined by default and you may replace them with you own:

  • wiki_user - Renders user name or link by given user object. By default renders <Unknown> for nil and "User#{user.id}" for others.

Configuration

Configuration options are acessed via Irwi.config object. Currently supported options:

  • user_class_name - Name of user model class. By default - 'User'

    Define a method named 'current_user' method on WikiPagesController that returns the object for the current user

  • formatter - Formatter instance, which process wiki content before output (see section below).

  • paginator - Paginator instance, which display pagination controls (see section below).

  • comparator - Comparator instance, which builds and renders a set of changes between to texts. By default instance of Irwi::Comparators::DiffLcs is used (requires diff-lcs gem).

Formatters

Irwi supports custom formatters which can be configured by setting Irwi.config.formatter to corresponding instance. Each formatter should have method format, which gets a string and returns it formatted.

There are several supported formatters based on different gems (which tou should add to Gemfile of your application):

  • Irwi::Formatters::RedCloth - markdown formatter based on RedCloth gem.
  • Irwi::Formatters::RedCarpet - markdown formatter based on `redcarpet gem.
  • Irwi::Formatters::BlueCloth - textile formatter based on BlueCloth gem.
  • Irwi::Formatters::WikiCloth - formatter based on wiki_cloth gem.
  • Irwi::Formatters::SimpleHtml which does nothing.

By default, Irwi will select first available (having corresponding gem in application Gemfile) formatter. Also, you may select formatter explicitly by specifying Irwi.config.formatter value like:

Irwi.config.formatter = Irwi::Formatters::BlueCloth.new

Paginators

Irwi supports custom paginators which can be configured by setting Irwi.config.paginator to corresponding instance.

There are following supported paginators (which tou should add to Gemfile of your application):

  • Irwi::Paginators::WillPaginate - based on will_paginate gem.
  • Irwi::Paginators::Kaminari - based on kaminari gem.
  • Irwi::Paginators::None which does nothing.

By default, Irwi will select first available (having corresponding gem in application Gemfile) paginator. Also, you may select paginator explicitly by specifying Irwi.config.paginator value like:

Irwi.config.paginator = Irwi::Paginators::WillPaginate.new

Access control

If you want (and it's good idea) to specify which users can see or edit certain pages you should simply override following methods in your controller:

  • show_allowed? - should return true when it's allowed for current user to see current page (@page).
  • history_allowed? - should return true when it's allowed for user to see history of current page (@page) and compare it's versions.
  • edit_allowed? - should return true when it's allowed for current user to modify current page (@page).

Attachments

Irwi allows easy attachment integration in your wiki. There area several simple steps to add attachments to wiki pages:

  • Call irwi_wiki_attachments generator. It will create WikiPageAttachment class.
  • Include config.gem "paperclip" in your environment.rb or, if you prefer another library modify generated code for it.
  • Append to initializer (or create a new one) something like Irwi.config.page_attachment_class_name = 'WikiPageAttachment'.
  • Run rake db:migrate and start using attachments in your wiki!
