Mousetrap

[PierreMartinon]

Current status:

• OCP definition
  • [x] (re)load a .jl file: assume problem name is "ocp"
  • [x] open a .jl file in external editor
• solve the problem
  • [x] solve with default options: solver output in julia REPL
  • [x] save/load solution: julia JLD2 format
  • [x] export solution in JSON format
  • [x] warm start
  • [ ] set options for solve: BUG IN ENTRY WIDGET :(
• plot the solution
  • [ ] display of CTBase plot: in standalone window BROKEN :(
  • [x] save the graphs

Nice @PierreMartinon! Making progress with the GUI 🙂

[PierreMartinon]

Added load/save solution using julia JLD2 format, since OCP solution contains complex objects such as interpolated functions, not easy to handle with JSON

[PierreMartinon]

[maybe] try Logging package to display ipopt output in GUI frame via a text file ?

[jbcaillau]

@PierreMartinon @ocots looks a bit like it is a graphical alternative to the REPL approach

[PierreMartinon]

We'll discuss this with Olivier yes. The usage is a bit less clear than for a c++ code such as bocop2, since we do have the julia REPL. Having interactive graphs and a julia REPL inside the GUI would be neat though :D

I'll try to see the limits of this package, then have a look at QML, which may be more powerful, but probably more complicated too. Although a QML interface could be hooked to bocop3 as well, which would be a significant benefit. I'll need to check the practical feasibility though.

It is unfortunate that the old QT gui for bocop2 is written in QTcreator's specific format (.ui) that is not exportable to the more portable .qml format. I'll try to update it for bocop3, and see if we can call julia from c++.

@PierreMartinon worth a try

[PierreMartinon]

Mousetrap is nice yes, but is a bit similar to PySimpleQT I used for bocop3: it is a simplified wrapper for a lower-level UI library. As such, it is very good for the quick development of basic GUIs using high-level languages, but typically suffers from limitations.

[PierreMartinon]

Added plot save. Solve options also added as Dict and passed to the solve call sucessfully. Unfortunately on the UI side the Entry widget seems bugged and does not retrieve the input text. Maybe linked to the following error message:

No IM module matching GTK_IM_MODULE=ibus found

As of now, this concludes the first experiments with Mousetrap. Moving on to QML.

[jbcaillau]

@PierreMartinon please plan a little demo for our next meeting!

[PierreMartinon]

Sure. Additionaly, I'd be interested to know if the same bug occurs on mac. The test.jl script in mousetrap/ does just the faulty Entry button.

I do not manage to execute the code:

Added warm start

Also encountered another problem with FileChooser unable to create new file (for save as... function)
