Re: [Gimp-user] Scripting, toggles and accessing the application state

[Rick Strong]

Another approach is to duplicate the layer you are working on and put it 
above the original layer. Turning the dupe layer on/off will reveal the 
changes.

This is unfortunately not true for german kezboards...

Re: [Gimp-user] Scripting, toggles and accessing the application state

[Rick Strong]

I understand the technique having used Photoshop for 27 years. I have scripted 
Indesign, Pagemaker, Corel draw (made it draw pie charts with callouts from a 
simple list of data), Word, Excel. It was fun but the time I spent debugging 
was better put to use using the other side of my brain and being creative. 

That’s just me. 

Sans souci,
Rick

I answer on this thread, the other one (no subject) was another mistake of my 
part. 

So as Jan said we aren't all that fluent in typing. 

My personnal reason is that I used Photoshop for 21 years now and I consider 
that a program should yield to its users' needs and not the other way round. 

For example I need a toggle when working on an image for which I have a sketch. 
Sometimes I need to show the layer with the sketch, then hide it then show it 
then hide it to see what is on the sketch that I lost on the image I built. 
Pressing F8 repetitively in very rapid strokes generally do the trick. Don' 
forget to half close your eyes as well



Cordialement,

  Question 3) As far as I understand it, it is not possible to have toggles
  at the moment. Ctrl z twice will cancel 2 actions instead of undoing and
  redoing the last action. Am I right?

To some extent...; You can't take Excel and require it behaves like 
Photoshop. A program also has its own "philosophy", the more you stick 
to it, the happier you are. As they says the hard part is not learning 
Gimp, it's unlearning Photoshop.

For example I need a toggle when working on an image for which I have a
sketch. Sometimes I need to show the layer with the sketch, then hide it
then show it then hide it to see what is on the sketch that I lost on the

This is a two-lines script (plus 10 lines of boilerplate script 
registration code)

Yes


Question 2) Can I access the application state through scripts? I mean is
it possible to know if a layer mask is already added to the active layer


Yes


or if the layer palette is visible?


No. Scripts have no direct control on the UI.

There are parts of the UI that are toggles (for instance, Tab to 
show/hide dialogs, or Ctrl-T to show/hide the selection). It is normally 
useful to undo several steps in most applications, and I don't remember 
ever using an application where Ctrl-Z is a toggle as you describe (but 
there s no real standard for the "redo" shortcut)


You'll find there are two languages supported out of the box to write 
scripts: the historical script-fu (a LISP dialect),  and Python. Unless 
you are already well versed in LISP/Scheme, use Python.
