Boolean 'not' operator does not display correctly in Numbas.jme.display.texify #422

Closed graemechester closed 8 years ago

graemechester commented 8 years ago

I have been experimenting with writing custom scripts to use JME for checking Boolean expressions, it seems to be working OK but the input box won't accept '!' or 'not' operators. The error message reads:-

texOps[tok.name.toLowerCase(...)] is not a function

I traced this through and found that both ops are translated to 'not', though only '!' is define in texOps. Both the editor and runtime are affected.

Whoops, can't think how long that's been broken! Fixed it. Thanks for letting me know.

Thanks for the quick response – looks like no-one else is using Booleans!

Kind regards,
