SketchUp RUBY API Wishlist [way of coding wishes, please]
-
Scott,
I 've got one, almost a Christmas wish : - can Ruby tell me if I should use UVHelper instead of uv_at when I want to get proper UVs for a face, PLEASE!I other words - can Ruby tell me if the face's texture is photo-matched or not?
Please check this thread. Could it be an additional .materialType result .. say 3?Tomasz

Thanks for starting this topic, Scott!
Ok, I split this topic off from the earlier posts and made it sticky. Let the wishing continue...
-
Fix onMButtonDown() api.
-
Here is one (of 1000):
The text and dimension tool are not accessible from Ruby. You can't read or set the text for example.
-
The Sections are hardly accessible from Ruby, only through Selection! You can't read or set it active.
-
This is music to my ears, Scott. Here's another vote for ruby control of dimension objects. CB.

Two requests:
Simple methods for retrieving points,angles and distances without using a tool class.(Something as simple as 'getpoint' and getangle in AutoCAD's api. Maybe something like pt=Sketchup.utility.getpoint(prompt) for example)
'Getangle' should offer the use of the protractor tool for input.Then a request for the Sketchup COM api: Include a 'runRubyScript' method that can be called from the api and returns the return value from the script.

Hi all !
One great improvment would be to have some control on inferences via ruby... Isolate, stop, start, etc.... -
Move (and rotate) axes from ruby !!! Actually, to be able to access any tool from ruby.
regards!

Hi all !
One ruby improvment :- A command autolisp like function !! To have access to all native tools (like said NewOne), and to have possibility to control this tool !
Command autolisp function work like that :
To make a line :
(command "_LINE" "0,0,0" "10,0,0" "") (command " 'International Name of the tool' " " 'first point' " " 'any point you want' " "")"" stops the command.
One very intersting thing is you can insert pause that let user doing what he wants !(command "_LINE" "0,0,0" PAUSE" "")PAUSE stops process and let user giving a point, in this example.
Another cool thing is an Autocad variable that show if a command (or tool) is active. And you can use it in the code !(command "_LINE")(while (not (eq (getvar "cmdactive") 0)))(command PAUSE))(getvar "cmdactive") returns 0 (no active tool) or 1 (one active tool)

Selection display bug to be fixed, please.

Something I have been wanting to do is write a suite of general-purpose Observers based on the built-in ones. Most of the Observers are designed to be attached to a specific entity in a model (or to THE model) - the SelectionObserver, for example is attached to a model's selection collection. It just seems inefficient and error-prone for each plugin author who needs one to implement their own SelectionObserver when a single instance can handle all requests.
So, I guess I'm really proposing a simplified API for using Observers.
The way I see this API working is that a plugin would 'require' the observer file, which would create a single Observer instance. Then the plugin would 'register' methods in the form of blocks (or procs?). In my experiments, I used the Ruby Singleton class to ensure there is ever only one instance created.
Here is how I see the API being used (without getting into the details of the implementation):
# My Plugin require 'app_observer' # Global AppObserver instance created def hello(args) puts "Hello #{args}" end # Register hello() to be called for an onNewModel event id = AppObserver.instance.register("onNewModel") {|args| hello(args) } # AppObserver attaches itself when its registry goes from 0 to >0 elements ... AppObserver.instance.unregister(id) # stop calling hello for onNewModel event # AppObserver detaches itself when its registry falls to 0 elements.It really simplifies using Observers, which in turn could allow authors to create better plugins, with more advanced features, in a shorter time. It may also save on resources by having one and only one instance of most of the Observers (confirm?)

Jim,
Nice idea. Also, I'm curious if you mixed in the Singleton module to implement your singletons? I've found that I can't require a library module like Singleton unless I point directly to my Ruby installation directories. I realize that this isn't required to implement singletons, but it seems the most simple and consistent.

Welcome to SCF Scott, it's great to see your involvement here!

This is a fantastic idea. Attaching observers reliably to every component instance, for example, is challenging. So a helper script is one approach... another would be to create some uber-observers at the Sketchup level. Obviously, there are potential performance concerns with any of these.

A standard for displaying script documentation, besides their description, in the menus:
The ruby filename, creator, version level; basically an "about" display for each script. Optional info could be copyright info, contact (email) link, website link, and display of a help file on a local drive.
=============================================
An easier way to organize scripts in a user defined menu (there are scripts that do this now, but I wouldn't call them user friendly)

New method for a texture, very useful for exporters.
texture.alpha_channel? -> (true or false) -

texture.alpha_channel? -> (true or false)Ooohhh..that reminds me:
How about a method that samples the texture color on a face?
face.color_at(u,v)->returns a SketchUp::Color object.
Could be used for displacement mapping inside SketchUp for example.

Hi David,
Yes, I used the singleton class from Ruby. I copied singleton.rb from the Ruby language installation to a 'ruby' folder in my Sketchup/Plugins folder. The Ruby singleton is very easy to use, and was simply the best and fastest solution. I think there are a few other files from the installed Ruby files that I needed also.

Hello
Inside SketchUp it works fine but when creating an AVI file with Export -> Animation
the - Sketchup::Pages.add_frame_change_observer - is not firing between frames.Is there anything i should change or another observer i can use between frames in Export Animation ?
Thanks
