This doesn't work at all in Windows 7. Special:Example is not found, and no error are printed out. I'll spend some more time trying to figure out why this doesn't work. I copied all the files from examples\Example\ on the SVN trunk, but none of them work so far.
I was updating the wrong directory. I apologize for the confusion.
The tutorial is outdated
Point number 2 in this section reads "Modify the 'execute' method in Example.body.php to print out 'hello world!':". However, there is no such file in the cloned repository.
I found the file instead at the svn repository.
- There were several remaining references to Example.body.php which I replaced with SpecialHelloWorld.php as well as updating the i18n sections to be appropriate for the new JSON format. Psoplayer (talk) 16:37, 12 June 2014 (UTC)
