Problem when entering variables for functions and problems with print command interpretation

[XDK-Support]

Mita in general seems to struggle with interpreting variables and brackets in certain functions, here are a few examples i stumbled upon using the XDK 3.5 workbench

• Entering variables

  every (1*100) milliseconds {}
  var test : uint32 = 100;
  every (test) milliseconds {
      //every accepts nothing but a blank number, no variable or anything but a blank number
      //bringing up the error " no viable alternative at input '(' "
  }

  same with setups, this also is the correct type for standby_time

  let test : uint32 = 1000;
  // -- optional setup of the BME 280 environment sensor
  setup environment {
      power_mode = Normal;
      standby_time = test; // ms
      // Couldn't resolve reference to EObject 'test'.
      temperature_oversampling = OVERSAMPLE_1X;
  }

• println will cause the workbench to freeze up, but be accepted in mita code

  var tempCorrection = 6.5975;
  println(`${(tempCorrection/tempCorrection)}`);

  but will result with generated code in application.c

  printf("%.6g\n", tempCorrection / tempCorrection;);

  if we leave out the round bracket

  var tempCorrection = 6.5975;
  println(`${tempCorrection/tempCorrection}`);

  resulting in

  printf("%.6g\n", tempCorrection / tempCorrection;);

  other Mita println issues:

  println(`rotations in mdeg/s`); // -- nope, in will be picked up an operator
  println(`rotations as mdeg/s`); // -- nope, as will be picked up an operator

Hi,

indeed, referencing variables is not supported everywhere intentionally. We might extend this in the future but for now in some places static values must be used.

We will look into your println-bugs, thanks for the report!

I can reproduce the UI freeze

[tkutz]

The UI freeze looks like an Xtext bug for me. Still trying to break it down to something small and reproducible. It is related to syntax highlighting: if the string-like highlighting is removed (ProgramDslSemanticHighlightingCalculator) the UI does not freeze anymore.

The UI freeze is fixed with PR https://github.com/eclipse/mita/pull/294

The last issue with in and as within println statements will be fixed with PR https://github.com/eclipse/mita/pull/322

Closing due to fixes in #294 and #322
