Re: Cannot reference driven constraint

Thanks for the explanation. - Is there a list of special names not to be used in expressions? Not in the documentation, but you can find all of them in src/App/ExpressionParser.l. - Is there a possibility to notify the user when he enters such a name? That should be possible, so please register a f...

Re: Cannot reference driven constraint

Eivind Care to weigh in? Hi, Both h and rad are reserved, as they are also units (h = hour, rad = radians). Even if they are unambiguous when used as a name (like Contraints.h), the parser does not understand that, as it parses word by word, and h and rad are immediately identified as units. Eivind

Re: Expressions... again...

If you quote them with << and >>, then it works in both cases. You can't use "normal" quote characters like " or ', because that is interpreted as units. Hi Eivind. I noticed one issue when helping an user to get a value out of dictionary into a spreadsheet cell: https://forum.freecadweb.org/viewto...

mh - I can readily reproduce the issue on all systems I have access to. Could you describe the steps you take trying to reproduce? Maybe I can spot the difference.
I've managed to recreate the problem now.

It's not supposed to fix it, it fixes issue #3197, the expression completer.

Eivind

Note that this fix does not resolve the initial issue, it just fixes the crash. The expression not updating properly is still present in the current branch (Git d95a65b260b2a8c).

Re: Update issue with expressions

However, could you please see whether this prevents your crash? Yes, this fixes the crash. Btw, shouldn't the line ssize_t i = static_cast<std::size_t>(tokens.size()) - 1; be changed to ssize_t i = static_cast<ssize_t>(tokens.size()) - 1; because a static_cast of size() to std::size_t is pointless?...

Re: Update issue with expressions

Some remarks: there is a new bug introduced with the last PR inside ExpressionCompleter::slotUpdate. The iteration variable i can become equal to tokens.size() and thus tokens causes a crash. With above attached project and the expression of "Step Down" this line ssize_t i = static_cast<std::size_t...
