OMEdit quoted identifiers breaking highlighting

OK with the new nightly the lexer issue is fixed. The syntax highlighting issue is still there. BTW, I ran the model and I also go ``` Process crashed Simulation...

Fix the WeeklySchedule C parser to handle \r character properly

Adding @AndreaBartolini, @deepak19015 to the loop.

Fix the WeeklySchedule C parser to handle \r character properly

@mwetter I guess you will also port the fix to 10.0.x and 9.1.x, right?

Division by a wrong value in an algorithm?

I think @phannebohm's analysis is correct. In fact, the problem arises after the fault has cleared, when unfortunately the nonlinear solver latches on a bogus solution with extremely low voltage...

Modelica-Buildings Library (master): Iteration variable is NaN at initialization due to poor causalization of if-equations with many equations per branch

I checked further the `SpaceCooling` model and I think I have a good trail. The model has three Boolean variables` mulStaDX.watVapEva.off`, `sinSpeDX.watVapEva.off`, and `varSpeDx.watVapEva.off`, which are switching a large number...

Modelica-Buildings Library (master): Iteration variable is NaN at initialization due to poor causalization of if-equations with many equations per branch

Hmm, I added `max = 0.05` to the declaration of `XEvaWetBulOut` but I still get divisions by zero. I turned on -lv=LOG_NLS_V, it turns out the first divisions by zero...

Modelica-Buildings Library (master): Iteration variable is NaN at initialization due to poor causalization of if-equations with many equations per branch

> `xloc` is the local name for the array of iteration variables in an algebraic loop inside our generated C code. We do a NaN check at runtime, currently for...

Modelica-Buildings Library (master): Iteration variable is NaN at initialization due to poor causalization of if-equations with many equations per branch

@bilderbuchi see #12193.

Modelica-Buildings Library (master): Iteration variable is NaN at initialization due to poor causalization of if-equations with many equations per branch

I guess some simple heuristics could already do wonders. If you have this pattern ```modelica if then v1 = ; v2 = ; v3 = ; else v3 = ;...

Implement code refactoring in OMC/OMEdit

See #3915 and #5346
