How to get in Ruby the list of templates


#21

I did notice that, I guess that the original developers did drove them selfs in a kind of deadlock; continue with blisters and bandage or rewrite a massive piece of code. Happens often, also with Lotus Notes and Formula, they also did have to rewrite that. Maybe SU has to rewrite the events for the model engine.

Anyway, I did try this to get your idea working, but it crashes.

I did put some messageboxes in there to look at the call order. I notice that when I wait to dismiss the messagebox with “build_menu_item - menu not loaded yet exit” it crashes directly after, but if I am quick I get also the to see the " build_menu_item - exit" message. But then it crashed direclty after that. My guess is that it happens because of removing the observer. If I remove that line, then it so far works, but if that is the purpose…
( BTW, is there a kind of keyword like LINE or FILE but for a def or module to shoe in what for def the code is executed? )

Yes, it is __FILE__ and __LINE__.

And from the Kernel module, the global method __method__.
You should also understand caller, and caller_locations and the Thread::Backtrace::Location class.

Do not use modal messageboxes to debug code. Open the Console and use puts calls.

Try a timer then …

UI.start_timer(1.0,false) { Sketchup.remove_observer(self) }

… this would allow the observer callback to return before the observer itself is removed from the application’s observer queue.


#23

About puts, I knew, but then the only way I (know) can use the console is to disable MyPlugin open the console and then enable MyPlugin, but then the load order with other plugin’s are different. So the ui.message is easy when directly from the start with the plugiin always enabled.

Also because of the pause, by not quickly dismissing the dialog, I notice the time needed by the observer.

Hmm, maybe there is SU.command to open the console. Bu that is for tomorrow.

The timer works, perfect thank you.

Good night

@eneroth3 has a auto console opener plugin somewhere.


#25

Aha, this becomes bed reading :wink:


#26

I found this from @DanRathbun (and others):

https://groups.google.com/forum/#!topic/sketchupruby/kplzdNOyclM


#27

Yes, that is 8 years old, but it still works for all SketchUp versions …

Sketchup.send_action("showRubyPanel:")

… whereas …

SKETCHUP_CONSOLE.show

… will only work for SketchUp 2014 and later.

So you could use …

SKETCHUP_CONSOLE.show rescue Sketchup.send_action("showRubyPanel:")

… to cover all possibilities.

:wink:

Great tip, merci beaucoup. Gives extra info.

Is there a serious book about the in’s and out’s of Skechtup and Layout ( with development in mind )? Not about ruby but specific SU. I did see happily that Layout can accept plugins, but very less information or samples?


#29

Not “live” plugins yet. LayOut does not have a Ruby subprocess (yet.)

We can only read and write to .layout files from within SketchUp’s Ruby, … or from 3rd party C applications.

See the Books list and it’s “SketchUp Specific” section of my WikiLists thread …

… also see the official SketchUp book list …

I want to do the same for Layout. So far as I can see I can load the template names bij using a hardcoded path.

Anyway, when I do have a path to a LO template, it doesn’t load.
If I save a template.layout I can’t, read it won’t, load in Layout.

This is the simplest code and copied from the docs.

doc2 = Layout::Document.new("/Users/dev/Library/Application Support/SketchUp 2018/LayOut/Templates/A1 Landscape.layout")
# doesn't work, I do get a ref pointer in the console	    

tfile = "/Users/anubis/Desktop/Untitled.layout"

puts("#{__method__} - Layout start loading")
doc = Layout::Document.open(tfile) 
# nothing get opened. I do get a ref pointer in the console
     
definitions = doc.auto_text_definitions
definitions.each { |auto_text|
puts("tag : #{auto_text.name}")
puts("name : #{auto_text.tag}")

#definitions.remove(auto_text) unless auto_text.mandatory?
}
puts("#{__method__} - Layout loading done??")

What do I wrong? I can’t find a doc.show command.

BTW In the mean time I use

system( "open '/Users/anubis/Desktop/Untitled.layout'")

Since I don’t have your files, I can’t say why your attempts to open it in the API don’t work. They work for me with my files. Maybe the problem is with what you expect from the methods #new and #open? These create a Layout::Document object instance within the current SketchUp Ruby session and provide access to it for manipulation. It is somewhat like the external SketchUp C SDK except embedded in the SketchUp Ruby API. They do not launch LayOut or open the file in LayOut itself. There is not (yet) any API method to launch LayOut and tell it to open a Document.


#32

Just as an aside.

The following method call works on Windows to get a working path to the user’s LayOut templates folder.
Does it also work on Mac ?

Sketchup.find_support_file "../LayOut/Templates"
#=> C:/Users/Dan/AppData/Roaming/SketchUp/SketchUp 2016/SketchUp/../LayOut/Templates

This alos gives a working path to a Program Data distro templates folder …

Sketchup.find_support_file "../LayOut/templates/Paper"

Does it also work on Mac ?


doc2 = Layout::Document.new(
"/Users/dev/Library/Application Support/SketchUp 2018/LayOut/Templates/A1 Landscape.layout"
)

I don’t have a template named "A1 Landscape.layout", … is this a custom template of yours ?


(Please use ```ruby tagline to start your code blocks.)
