OMNotebook is not able to plot $cpu_time

[Lennart Ochel]

If I simulate with simflags=”-cpu”, it is not possible to plot $cpu_time from OMNotebook.

[Lennart Ochel]

I try to do something like this in OMNotebook:

loadString("
model test
  Real x;
equation
  x = sin(x) + time;
end test;
");
simulate(test, simflags="-cpu");
plot($cpu_time)

But I get only that error-message:

Error occured building AST
Syntax Error
[<interactive>:9:6-9:6:writable] Error: Lexer failed to recognize '$cpu_time)'

In OMPlot and OMEdit everything is working quite fine.

I guess we can fix this in two ways:

1. rename $cpu_time to a modelica-valid variable name. But then we can get into trouble if that specific variable-name is used in any model.
2. maintain $cpu_time and fix the lexer instead

3. you can use quoted identifiers '$cpu_time'

Option 3: r15140

It is still not working! Maybe that is related to my corrupt OMNotebook installation. Can someone check that out?

loadString("
model test
  Real x;
equation
  x = sin(x) + time;
end test;
");
simulate(test, simflags="-cpu");
plot('$cpu_time')

[Lennart Ochel]

Option 3 was probably not a good idea - because that is the same as option 1. '$cpu_time' is already a valid modelica identifier, so we will get into trouble if someone will call a variable '$cpu_time'.

Ok. I'll see if I can add $cpuTime to the lexer. I don't like $cpu_time :)

[Lennart Ochel]

Ok - Now it is called $cpuTime. (r15143)

Added $cpuTime to the identifiers known by OpenModelica in r15144.
The example works now and $cpuTime is plotted fine.
