Hi Tim - I had a weird issue as I was testing some older questions just now. When using the JSME editor I drew a structure (butane) with the zig-zag tool - I overshot the length and brought it back. It was graded incorrectly (as pentane) as the editor was passing the extra carbon that I back-tracked. Hence the structure looked 100% correct, but was graded wrong. I have not seen this happen before. The JSME editor online test page does not reproduce this error. Any advice?

Hi Pawel,

It's working on v4.3 for us, and is supported, but we have a ton of plugins and I think that this is the least popular, so it's a case of when we can get around to it (though we make a concerted effort in June-September every year to release the latest version of our plugins with the latest version of Moodle we can test against).

However, our School of Chemistry have asked we look at something more modern. So we are about to look at https://moodle.org/plugins/qtype_molsimilarity and https://moodle.org/plugins/tiny_molstructure to see if that better meet our needs. So there is certainly the possibility that we will move away from this plugin in the next couple of years.

Good day
We are in the process of upgrading to Moodle 4.1 from 3.9.
Will pmatch / pmatchjme be updated to the latest versions of Moodle?

I have just released a new version which works with Moodle 4.0. Sorry that took so long.

Hi, Is there any plan to update the plugin in the near future to be compatible with moodle 4?

Yes.

We are still working to update this plugin, and that work is not complete yet.

Well after a year of teaching from home, recircling to revisit see where things can improve in the future...
Came back to this topic because of our continuing use of JSME without pattern match (and not sure about needing to convert 100s of questions from JSME to JSME with pattern match).
Anyway, I was just able to recreate our "old" problem (answer not saved) that we have in simple JSME with the JSME pattern match (triggered if a blank answer checked first, then new repeated drawing typically "lost"). We had previously revealed that this seems to be connected to the simple text match origins of this qu type (?) and I seem to recall being able to demo this on the OU site thus establishing it as not being an artifact of our set up. Having been using drawing questions for 20 yrs and 10+ with Moodle, it would be great to find a solution (we note that some browsers and devices make this worse than others). I'd love to hear from anyone else who has observed this, and especially anyone with a fix!

The code of the other question type bears no relation to this one, so I don't know. I don't have time to look into this myself, but our code is open source, and if it can help resurrect the other question type, then you are welcome to -steal- (I mean reuse under the GPL) it.

A few years ago we report the same type of problem described above (i.e. answer not being "saved" as drawn) with the simple JSME qu type (which is no longer being maintained I believe). Since the simple JSME feels like a simplified version of the pattern matching version, could the simple JSME be spawned (recreated, updated) from this qu type ? I have hundreds of JSME qu I want to be able to use...otherwise maybe I need to try to transfer JSME to pattern match...

Hi, can someone help me with these, please? Is this plugin good? Is it secure? Does it let moodle slow? Is it free? Thanks!

At the moment, there is no facility to do that sort of customisation. They would be good features to add, but I doubt we will ever do that. however, pull requests welcome.

Is it possible to activate optional parameters (rbuton, atommovebutton) in the version for moodle 3.8 ? And also to change the size of the editor ?
