A question that could check student's response against several regular expressions and could give next character and next word hints.
If you do not know what regular expression is, it could also work like Moodle Shortanswer question with hints, just choose "Moodle shortanswer" as notation and you could enter answers just like in shortanswer question type.

This question requires 5 other plugins to work. If you want easy install, download full archive from our Google Code site. You could unpack it into Moodle core folder (the one with config.php) and it will place anything where it belongs.
If you want to fully use Authoring Tools, you should also have Open Source Graphviz packet installed and path to it specified into Moodle. It is necessary to draw Syntax Tree and Explaining Graph.
