In this tutorial, you’ll learn how to create a nice “hello world” Typo textfilter plugin. It will just make a Javascript pop up appear at load time saying “Hello world”.
First, create a plugin using Rails default plugin generator
$ ./script/generate plugin typo_textfilter_helloworld
Load your plugin in your favourite text editor, and start with init.rb. You’ll need to load the Typo Textfilter Plugin API and your Helloworld class
require 'text_filter_plugin' require 'typo_textfilter_helloworld'
Now, edit your lib/typo_textfilter_helloworld.rb, this is where the big thing start
First, declare your Helloworld class :
class Typo class Textfilter class Helloworld < TextFilterPlugin::MacroPost plugin_display_name "Hello world" plugin_description "Adds a hello world pop up"
Now, add the method with the help text for your macro
def self.help_text %{ You can use `<typo:helloworld>` to have a stupid javascript pop up saying "hello world" } end
Now, create your macro filter which does all the work:
def self.macrofilter(blog,content,attrib,params,text="") %{<script type="text/javascript">alert('hello world');</script>} end
Close the unclosed classes and methods
end end end
In your code, you can call your hello world macro filter :
<typo:helloworld />
