Moodle plugins directory: Regular expression short answer

Hello Joseph,
great work, thank you very much!

Perfect in Quiz/Tests.

Imho you should add the 'missing links' for plugins related to question behaviour.
I didn't perform any tests if this plugin works without all redundancies to '... behaviour...' inside the version.php.

Hi Joseph

We are using the latest 2.5 version of this with the two question behaviours but there is an issue with saving the answers if the user goes back to revisit any questions. All of the sudden the answers have disappeared.. I found this post from a few years ago where someone was having the same issue. - https://moodle.org/mod/forum/discuss.php?d=68418
We're using the latest versions... any ideas?

Many Thanks

Andrea

This is what one of my computer science professors is saying about the newest version of regexp:

1. Its not matching as correct, things it should.
2. Wherever I had [ ] to match a whitespace it replaces that with ()
3. If I try to do [ ]+ to match one or more whitespace or some other potential character class [abc]+ I get the message that I cannot have an unescaped metacharcter + * ? $ in a question with a value of more than 0! This is crazy and kind of defeats the purpose of having regular expressions!

It worked in the previous version, 2.3.

Further to private exchange with Bob, the problem is dismissed.

Hello Joseph,

will there be a Moodle 2.7 version?

Best regards
Sebastian

@Sebastian,
Yes there will be a 2.7 version... when I have time.

What I can tell from my – albeit very basic – testing in Moodle 2.7, this question type seems to work flawlessly.

Would it be possible to extend the plug-in to multiple (short) answers (input fields) each compared to multiple regular expressions?
I.e.:
Question:
The critical section access control algorithm must meet these three conditions:
1. [ input-field ], 2. [ input-field ], 3. [ input-field ].

Answers (regular expressions):
1. for 50%: (mutual )?exclusion
2, for 25%: progress( in allocation)?
3. for 25%: bounded waiting
(Or each worth 1/3 of points.)

The answer from each input field would be checked to each RE and if a match is found that RE would be removed from checking remaining input fields.

The purpose is to allow multiple answers in any order.

Creating only one input field and requiring all the possibilities (separated by comma) would require complex RE mixing all possible orders and dealing with wrong parts. Multiple input field is much simpler.

Thanks for implementing or pointing me to the solution if it already exists.

Thanks for the permutation feature - I have found it very useful. I've also found that it seems to be limited to five options per set - I cannot get six to work. Perhaps this limitation could be documented?

I've read through all of the documentation several times and I am having a hard time understanding why meta characters are not allowed for accepted answers. I must be missing something, can someone please explain? Thank you.

Does the CLOZE integration of Regex still work with Moodle 3.3 ?

Hi, I can confirm the regex integration to the multianswer (cloze) type is broken for Moodle 3.3, do you have with up-to-date renderer.php and questiontype.php files ? Or when will have them ? Thanks

To be more precise, the existing renderer.php and questiontype.php files still work fine with the standard cloze question types but they block the new type, MULTIRESPONSE that was introduced in 3.2 (at least).

The description of MULTIRESPONSE can be found at https://tracker.moodle.org/browse/MDL-3782

will there be a 3.4 Version of this plugin?

Best regards
Sebastian
