Moodle Plugins Directory: Pattern match with JME editor

This question gives an error in the language pack. it occurs when we want to personalize the language settings.

Error is:
Duplicate entry 'en-361-smiles_C' for key 2 INSERT INTO mdl_tool_customlang (lang,componentid,stringid,original,master,timemodified,outdated,local,timecustomized) VALUES(?,?,?,?,?,?,?,?,?) [array ( 0 => 'en', 1 => '361', 2 => 'smiles_C', 3 => 'aliphatic carbon atoms', 4 => 'aliphatic carbon atoms', 5 => 1330189912, 6 => 0, 7 => NULL, 8 => NULL, )]

thanks nice info..video pool

Error in language pack in version 2.3 (2012081600) occurs too. Very sad for us.

We're about to start looking at 2.3. I'll get this issue fixed as part of that.

Just to explain what is going on here. There are actually two different strings here: smiles_c and smiles_C. You can see those are different. I can see those are different. MySQL thinks they are identical.

However, it is probably not a great idea to have two language strings that differ only be upper/lower case, so I will fix this.

Ah. Well of course in SMILES 'c' and 'C' have clear, and different, meanings. 'c' is aromatic (as in benzene rings); 'C' is aliphatic (straight chains). Which tells you what to call them to distinguish them for the SQL.

Hi,

Thanks for fixing this Tim. I was using get_string to fetch the human name for the SMILES character suffixing the character with 'smiles' and then passing it to get_string. I guess one way to fix this might be to prepend big_ onto an upper case character and convert it to a lower case character appending that to smiles and looking up the translation with get_string

That is roughly what I am doing. I will ask you to peer review the patch when it is done.

OK, Jamie liked my patch, so the code is now available from github. Download links like https://github.com/moodleou/moodle-qtype_pmatchjme/zipball/MOODLE_22_STABLE or https://github.com/moodleou/moodle-qtype_pmatchjme/zipball/master

Now is OK, new install was without problem, upgrades problem was in history track.

I had a client reported the following JME problem. Please help to identify the issue.

The JME editor now seems to work perfectly; however, the question engine does not recognize either of the correct answers when they are given. I assume this is a problem with the pattern match mechanism, since there is a function in the JME Editor to acquire the SMILES string and it is identical to the SMILES string entered in the question (although the question version requires escape characters, as per the manual: http://labspace.open.ac.uk/mod/oucontent/view.php?id=470268&section=5.5.2).

George can you find out exactly what the molecule or the correct answers are so that I can try them.

Hi all,

please read the following FAQ created recently, it hopefully explains how to clarify this plugin better.
