SketchUp RUBY API Wishlist [way of coding wishes, please]

UI.openpanel - bugs and improvement requests

I would like UI.openpanel to be much more powerful.

I have at three problems with it.

Patterns for file extensions

This first code snippet should display all files with either a .zip or .rb extension.
When I use it in SU 7 Windows, the openfile panel displays only the .zip files, (no .rb files), and showed this '*.zip;_.rb' in the File name box: (with an underscore instead of a *)

fn = UI.openpanel "Select a zip file.", "",  "*.zip;*.rb"

When I pass it just one extension, it works:

UI.openpanel "Select a zip file.", "",  "*.zip"

But if I pass it a starting folder it fails:

UI.openpanel "Select a zip file.", "c;/tmp",  "*.zip"

showing '_.zip' in the File Name box

Passing patterns and a starting file separately

I should be able pass a file name (e.g. the last file the user opened), as well as a set of patterns.

Passing filters.

The Windows openfile dialog allows you to pass a set of filters which display at the bottom. UI.openfile should have a similar set of patterns.

#2 and #3 could be implemented with new, optional parameters.

Required file

Windows Openfile has a setting that required that the user enter a valid, existing file. This would be a nice feature for UI.openpanel.

Bug/new feature request for Sketchup.load

Sketchup.load does not set the filename or binding properly. errors during loading are not reported, and executaion errors are not reported properly.

Here is a test file with an error which only occurs during execution.

rps_test1.rb


printf "rps_test1.rb\n"
def test1
        printf xxx
end

When you load it with ruby's load and execute 'test1' you get this error:


Error; #<NameError; c;/tmp/rps_test1.rb;6;in `test1'; undefined local variable or method `xxx' for main;Object>
c;/devc_2005/rptools/rpt_debug/ruby/rps_test1.rb;6

When you load it in Sketchup.load (either the .rb or the compressed .rbs), you get this error message:



Error; #<NameError; (eval);11;in `test1'; undefined local variable or method `xxx' for main;Object>
(eval);11

Having the file name and line number for a ruby is very important both when creating a ruby application and when debugging client problems. I have to go to a lot of trouble to work around this bug.

Assuming that 'eval()' is eventually used by Skethcup.load to load, binding and a file name could be passed to cause errors to be reported properly.

e.g.: eval(string, TOPLEVEL_BINDING, filename, start_line)

I haven't read through this post, so some of these might be duplicates. If they are, consider mine a +1.

Expose the Surface class.
Change the data model for Text so its not a global thing, but an entity thing. That way, each text-related entity can have it own font and other attributes.
Expose Dimensions.
Fix all the bugs I've reported. Really.
Thanks, Todd

Sorry if off-topic.
But... did you guys heard something about Sketchup 7 ruby documentation? What's really new here? Will it appear? When?

Thank you.

We summarized the new SU7 features in a blog post:

http://sketchupapi.blogspot.com/2008/11/whats-new-in-sketchup-7.html

I can't give an exact date for the detailed documentation. We're working on it.

Thanks,

My suggestion of way of coding: Being able to hook up a debugger. Sorely needed some times.

NewOne

To be able to add new menus in SketchUp menu bar.

Extend the UI class to support the selection of a directory. Currently you can select files, but there doesn't seem to be a way to select a directory or folder.

The New Ruby API documentation is up and running.

Take a look at:

enjoy.

How about a method to refresh the SketchUp display when executing long scripts? Today the interface looks like it is frozen when you change focus to another window and then back to SketchUp. The display gets refreshed only when the script completes or a dialog box that requires user input is displayed.

Hi all!
To have possiblity to call a tool by its ID, with function Sketchup.send_action.
For example :

Sketchup.send_action 21022

It works great on PC. On Mac, it returns this bug below in the console :

Let me add my two cents. I've only been using the API for a couple of days now, and I can see that dimensions aren't accessible from it. This would be very important to me. I can see it's been requested a couple of times already...

Thanks for such a great tool.

Just thought of another one. Last night I tried to create a script to let me control the camera like you would in a video game: WASD and mouselook. Turns out that key press events are consumed by shortcuts before they can get to a script. Also, you can't copy the shortcut keys, change them temporarily while your tool is running, and then restore them when it's deactivated. A way around this would be nice. I know the walk tool lets you use the arrow keys, but it would be nice to a) be able to change those keys and b) use mouse look at the same time

You can work-around this dimensions_not_being_API_accessible issue...
Make a component-dimension one_unit long and save it
In the script insert it at the first picked point, then transfoem it...
Rotate it to the angle given by the second picked point and scale it in its X to match the distance_between_the_two_points : one_unit
The dimension numbers should change to match, which the ticks and leaders remain fixed.
You could have a third picked point to locate the text and scale it in the Y to suit ?
You could then explode that instance if appropriate...

If its not going to be part of the core program, then a way to export as a Flash Animations.

A means to use object tweening within a scene or between scenes [ie., apply a name to a group ie., Object1<TweenBegin> in Scene1, and on Scene2 place a copy of that object with a name of Object1<TweenEnd> ]. Any transformations to Ojbect1<TweenEnd> such a scale, position, and rotation would be tweened between Scene1 and Scene2 at whatever frame rate the user designate to the properties of objectname<TeenEnd>.

Maybe I am thinking about this wrong but I think a good idea is to develop a rubygem that exposes the SketchUp Ruby API to a standard ruby install. You can continue to develop the embedded Ruby capability but a lot of existing Ruby capability/code/gems can be put to immediate use. The relieves the pressure to urgently add capability that exists someplace else. For example I may want to couple SketchUp to a RubyOnRails environment. I don't expect you to embed ROR into SketchUp. I would have the capability of doing it on my own if I could access the Ruby API from a standard Ruby install.

Also, as I understand the Sketchup Ruby API is based on 1.8.0. Exposing the Ruby API to an external Ruby environment would allow users to use a more current release.

Does this make any sense?

This is music to my ears, Scott. Here's another vote for ruby control of dimension objects. CB.

nice post!
ok, how about this my officemate send me a cad file to be SU, problem is when i import them to SU the lines in 2d are not they seem to be.. they are in different axis can SU place it in one axis,

(is this an existing ruby script?
if so kindly send to me)

I'm experiencing the same problem with a routine that generates thousands of faces. The calculation is sometimes very long, but with the screen locked is impossible to understand the percentage of completion and when the calculation will end.
You have found a solution in the meantime?

I have a SketchUp RUBY API Wishlist:

A ruby script that coverts multiple lines to 1 whole line.
A ruby script that speeds up shadow rendering.
A ruby script that ables a follow-me tool to cross multiple lines "For example: a cross using any shape"
A ruby script that Measures a volume of a model in Gallons, Liters etc..

Have a look at weld.rb http://www.smustard.com/script/Weld

@unknownuser said:

That would need to happen in the core SU code i.e. google needs to do that.

@unknownuser said:

Hard to know what you mean without more details. Could you post a pic in a new thread?

@unknownuser said:

There are a couple of volume scripts out there at the moment. Id guess it would be a fairly simple task to convert their output to litres/gallons. This would be a good place to start: http://forums.sketchucation.com/viewtopic.php?f=180&t=3188

p.s. I think this thread is meant more for wishes regarding the ruby API itself, rather than individual scripts.

My Volume scripts already let you select the results in gallons [US and UK] and litres as well as most other volume units...
