    Hi,
    Having an issue with questions where the pattern is looking for multiple matches in the same sentence, e.g. 'as x increases, y decreases' where I'm trying to match both the 'x increases' and 'y decreases' parts. The same answer works just fine if I put a full stop in between clauses, but doesn't detect a match for a single sentence. I'm quite wiling to accept I'm doing something silly, but any help would be highly appreciated.

    Would match_p0 (x_inc* y_dec*) give you what you want? i.e. x must be immediately followed by inc(reases) (proximity of 0 words between x and inc*) and y immediately followed by dec(reases))?

    Should of course have added the o and w matching options too so that any order of 'y decreases x increases' will work as well as allowing extra words. So complete it's match_owp0 (x_inc* y_dec*). Will that do what you want?

    Hi Phil,
    Thanks, the minimal working example always elucidates things! My syntax was off in the match. Should have read the documentation more thoroughly!

    Hi Tim/jamie/jil,

    Thanks for your hardwork providing us pattern match question type

    I have tried to create the pattern match question type when i entered the text "match_mow(Talk about what happened to the rooms in the house and why they couldn’t stay in a hotel Use two sentences)" in the "Answer" field then click "Submit".

    It shows error message "Missing closing bracket in code fragment "match_mow(Talk about what happened to the rooms in the house and why they couldn".

    Please let us know how to allow single quotes like "couldn’t".


    Thanks for your help in advance.

    I think you escape single quotes with a \. So couldn\’t

    Note that the question type works better if you just try to match the keywords, not every word in the sentence.

    Hi TIm,

    Thank you for your quick reply.

    "match_mow(Talk about what happened to the rooms in the house and why they couldn’t stay in a hotel Use two sentences)"

    Sorry in the above content it is not "single quote" it is given as a "left single curly quote"

    ‘ ‘ ‘ left single curly quote

    Thanks for your help.

    Sorry, I am not sure without some in-depth debugging that I don't have time to try now.

    Can you just avoid using that character?

    I have just pushed a major set of changes which adds helpful tools for teachers creating questions, and verifying that they work as expected. That is all thanks to the hard work of John Bedell and Colin Chambers.

    Guys, great plugin, thank you for the effort put in here.

    Is there a max number of answers that can be used? Does performance get affected?

    I'll find out shortly I guess, am about to try 100+ answers. Will feedback.

    Afternoon Guys

    Let me start by saying I love this question type, however, we have one issue with it, because it is not Moodle Mobile App compatible, we are not able to make use of it. Our school just recently implemented the Drag & Drop type questions into our quizzes, and thanks to a bug, they are not usable in Chrome on android devices(don't know who to contact about this), so while I'm chomping at the bit to teach my English teachers how to use your Patter Match question, IT does not work and is not supported by the Moodle Mobile App.

    Please could you guys look into this for us and give me some feedback as to whether you will be making it App friendly, I really hope you do because I think that our English teachers could make good use of it.

    Regards
    Gavin

    This is something we want to investigate when we have time. I can't guess when that might be. But, thank you for your enthusiasm for this question type.

    @Sakshi.

    Yes it works fine in 3.3, it's only issue is with the Moodle Mobile App, but I'm sure these guys will get that sorted out when they have the chance.
