ps Fred, if you are saving 3D points as attributes - what happens when a user moves the spline?

Very interesting question, that I did not ask myself (actually, I just inherited the method from the previous bezier.rbscript by @Last). But magically, it seems to work fine, whether you move, scale or rotate the curve.

There must be a trick!

But this macro is full of surprise, for instance with an undocumented method "curve.move_vertices", which allows moving the vertices of a curve without having to recreate one.

I had the same problem with binary strings, because Sketchup stops the decoding at first \0 character.

But if you just wish to store an array of fixnum, why don't you store it 'naturally'. Sketchup entity attributes does it well, back and forth. I used this for my bezierspline.rb macro, where I do store arrays of 3D-points in this way.

Thanks very much Todd.

There are strange things on the Mac, like the fact that several keys (alphas and numpad) do nt seem to be trapped on the KeyDown, but only on the KeyUp event. This is also the case for Tab, Del and Backspace. This may be due to the VCB interference.

I'll see what I can do.

Thanks again

Fredo

Thanks.
For the time being, I will follow your advice (and also use File.join instead of building the string with /

@unknownuser said:

how about using Sketchup.find_support_file "Plugins" and then File.join(Plugins_dir, filename) ?

This works on Windows as well.
My problem is know whether this works on Mac, since I have no Mac and I have not even seen Sketchup running on a Mac!!

Are you Mac User? If so,could you just cnfirm this works fine? Thanks in advance.

Todd,

Thanks for the offer.
Here is the script KeysForMac.rb. It adds a menu item "Prompt for Mac keys" in the Plugins menu. When you invoke it, you will be notified on which key to type in the Status bar. The test takes less than 3 minutes.

It normally generates a small text file KeysForMac.txt, which normally should end up in your folder equivalent on MAc to C:\Program Files\Google\Google SketchUp 6. Actually I just open the file with no directory reference, because this is another potentialproblem on Mac.

	fname = "KeysforMac.txt"
	f = File.new fname, "w"

Talking about Directory and file paths on Mac, I have another problem with my method to find script files in the Plugins Directory. On Windows, I use the following statements:

BZ___DirSU = Sketchup.find_support_file ".", "."
BZ___SearchDir = Dir["#{BZ___DirSU}/Plugins/BZ__*.rb"]

But it does not seem to work. Maybe you can find out what I should use instead on Mac.

Again many thanks for your proposal.

Thanks very much in advance Todd.

On my Windows XP laptop, I have this:

On the platform
PLATFORM = i386-mswin32
RELEASE_DATE = 2003-08-04
RUBY_PLATFORM = i386-mswin32
RUBY_RELEASE_DATE = 2003-08-04
RUBY_VERSION = 1.8.0
VERSION = 1.8.0

On the Keyboard
ALT_MODIFIER_KEY = 18
ALT_MODIFIER_MASK = 32
CONSTRAIN_MODIFIER_KEY = 16
CONSTRAIN_MODIFIER_MASK = 4
COPY_MODIFIER_KEY = 17
COPY_MODIFIER_MASK = 8

VK_ALT = 18
VK_COMMAND = 18
VK_CONTROL = 17
VK_DELETE = 46
VK_DOWN = 40
VK_END = 35
VK_HOME = 36
VK_INSERT = 45
VK_LEFT = 37
VK_MENU = 18
VK_NEXT = 34
VK_PRIOR = 33
VK_RIGHT = 39
VK_SHIFT = 16
VK_SPACE = 32
VK_UP = 38

On the Mouse control
MK_ALT = 32
MK_COMMAND = 0
MK_CONTROL = 8
MK_LBUTTON = 1
MK_MBUTTON = 16
MK_RBUTTON = 2
MK_SHIFT = 4

Still no idea about the other keys on Mac, and the difference between the concept of CONSTRAIN_MODIFIER_MASK and CONSTRAIN_MODIFIER_KEY.

It seems that there is at least a big difference between the two platforms in this area. So I would be grateful to a Mac user to advise on the principle to find out keys codes returned by the onKeyDown method on Mac.

Pixero indicated to me the following codes on Mac
Command/"Apple" = 1048576
Alt/Option = 524288
Control = 262144
Arrow Left Key = 63234
Arrow Right Key = 63235
Arrow Up Key = 63232
Arrow Down Key = 63233
Shift Key = 131072

But what about the regular alphabetic characters, the function keys, and the punctuation signs?

Ideally, someone having both platforms should be able to establish the correspondance, and possibility write a small utility routine to 'unify' the keys between the two systems (unless this already exists!). I can do it, if someone gives me the list.

Also, I'd like to know the rules for the value on Mac of the constant RUBY_PLATFORM, which apparently allows to detect which platform you run on. For Mac, I know at least the value 'powerpc-darwin'. However, what happens on more recent Macs, running on Intel and Leopard (I understand from an earlier post from Todd Burch, that there should anyway be the string 'darwin' in the constant).

I am sure this will be helpful to the Sketchup Community, to make sure that scripts released can fonction both on Mac and PC.

@fletch said:

So one tiny request (hopefully tiny) is there a way you could, after selecting the first point for the polyline tool, one could right-click and choose 'lock Z axis' and in this way it would draw all other points forcing them to match the exact elevation of the initial point? (This would be very handy for 'tracing' in plan view over the top of difficult geometry that one cannot seem to close/create a face from no matter what one does.)

The option exists actually. When you draw a curve the default behavior is to force all points on the plane defined by the first 3 points (cursor is a black square). However, if you press the Up Arrow (i.e. blue axis), the points of the curve will be forced on the horizontal plane defined by the first point (cursor is a blue square). This works as well for the 2 other axis planes.

It's easy anyway to replicate LangHandler with your own version you control (and anyway a GetString method that takes a default in case the string is not found).

My observations were that it's seems that the community of Ruby 'scripters' prefer to avoid proliferation of files and deliver extensions with one or very few files.

Several remarks:

1. you are definitely right. It is more elegant with a separate file, so that you can proceed with the translation without touching anything in the code itself

2. the Sketchup Ruby documentation is really poor . I did not know LangHandler, and furthermore, that it was provided in the standard tool librairies of Sketchup. The script itself is not commented. I am sure many of us would appreciate if the Sketchup team could improve the doc.

3. I will indeed adapt LibTraductor to manage strings in external files, in order to keep the additional functions I wrote on dialog boxes.

Thanks a lot for signaling this to me.

By the way, I never found a Sketchup macro that had a separate 'string' file, but instead I found many that were published as several versions of the same macro translated within the code (like bezier.rband fr_bezier.rb, also written by the same @Last Software). Is this because Sketchup Ruby programmers don't really bother, or because nobody knows really about LangHandler?

When I designed the script bezierspline.rbI indeed bumped into the problem of language translation, both as a script programmer and as a script user. I made some research on what existed in terms of practices and tools and found very little. In general, scripts are written in a single language (English usually), and then the script is converted by someone into other languages, by modifying strings in the code and renaming the script file. For instance you have bezier.rband fr_bezier.rbon the Crai Ruby Depot.

There are a few issues with this approach:

• Having several versions of the file makes it more difficult to keep potential upgrades and bug fixing in sync.
• Some errors can be made when translating strings embedded in the source code. You can forget to translate some, or accidentally translate strings that you should not.

So I came up with this small library LibTraductor.rband a set of practices to rationalize a little bit the coding and the language translation management of Sketchup scripts.

The principle is to provide a way to define and use strings that carry their own translated version.

Mystring = "Hi |EN| Welcome  |DE| Wilkommen |FR| Bienvenue"

The macro provides utility functions to support:

• The definition and usage of multi-language strings, including substitution patterns with %1, …, %9
• Mass assignment of string constants to variables
• The designing of dialog boxes, with language translation and built-in validation
• A few utilities on hash arrays (marshaling, un-marshaling, pretty print)

Usage: just drop the macro file LibTraductor.rbin the Plugins folder of Sketchup, and in your script just insert a statement:
require "LibTraductor.rb".

Test utility: I published a test macro LibTraductor_test.rbto show some examples. It adds 4 menu items in the Plugins menu of Sketchup.

Compatibility: the macro should work with Sketchup v5 and v6 (Pro and free versions, English and French). I tested it on Windows XP and Vista. I don't know however if it works on Mac

Strange things actually.
On a PC with Windows XP in French, Sketchup v6.0.277, I get the following:
Sketchup.get_locale --> "FR"
Skectup.os_language --> "EN" (so two characters only).

On another laptop, with Windows XP US International version and Sketchup v6.0.515, I get:
Sketchup.get_locale --> "EN"
Skectup.os_language --> "EN" (so two characters only).

So this new behavior you report seems pretty recent.

This is normal. For German characters, you do not need Unicode. So you should swith it off.
For MSVC, I don't know if there is an efficient way to enter the extra characters. I am personally using Notepad++.

This happens with French accents as well (I am using Notepad++ as my Ruby editor).
The method is to prefix the special character with a backslash within the string.
For instance "Gr\ö\βe"

PLEASE DO NOT START A DISCUSSION in THIS THREAD - the thread should remain small for performance reasons.

Edit 19 Oct 08: I released a comprehensive version of BezierSpline,version 1.2, which includes this extension. It is advised to refere to the following post:
http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=13563#p100509

The latest version of Bezierspline is now published on Crai Ruby Depot
http://www.crai.archi.fr/RubyLibraryDepot/Ruby/Newest_scripts.html

It includes:

• Classic Bezier curve, Cubic Bezier, Uniform B-Spline and Polylines
• Creation, Edition, insertion and deeletion of control points, curve closing, etc....
• A tool bar is available
• Better Mac compatibility (I still need a Mac User to confirm)
• Language translation available in English, French, German and Hungarian
• Some documentation, mostly in english

On language translation, I am still missing some languages. So if anyone speaking Italian, Spanish, Portuguese, Dutch, etc... wishes to help, here attached is the file containing the strings to be translated. Just do the translation, I will take care of the integration. Even better, if anyone is willing to translate the quickcard (1,5 pages), also attached as MS Word file. Thanks in advance.

Hi to all,

I was wondering if there was a way to give back control to the Tool message loop when performing a long calculations.

To be clearer let's assume you have a piece of code that may take a long while to process. Assuming it is executed in the context of a Tool, it seems that you cannot catch any event while it is processed (such as getting a key or click down). This may be because Sketchup is monothreaded.

I tried to call iteratively each piece of processing in a Start_timer call, but this does not work (in addition the usage of Ruby continuation, callcc, does crash the program).
If you start a seaparet thread, it does not work either (it seems that Skecthup API cannot eb executed ina separated thread).

If anyone has an idea, that would be helpful. It is a pity that Sketchup does not have a method for that!

Thanks

Fredo

On peut garder l'ancienne version. Il y a compatibilite dans les deux sens (on peut editer une courbe de Bezier creee par une macro avec l'autre macro), mais je me suis arrange pour qu'il n'y ait pas de clash entre les deux macros.

Je viens de decouvrir qu'il y avait un Forum francais sur le site. Interessant :esurp:

Je viens de publier une evolution de la venerable macro bezier.rb, avec plus de possibilites pour editer les courbes de Bezier et de nouvelles courbes (Cubic Bezier et B-Spline uniforme).

C'est dans la partie Ruby, mais comme cela concerne les utilisateurs de Sketchup, je vous fais passer le lien.

La macro s'appelle bezierspline.rb, et j'ai fait un peu de doc pour l'utiliser (bon ! la doc est en anglais, sauf un petit resume en franncais). Les fichiers sont attaches dans ce forum Ruby dans differents posts (du aux limitation du site pour les attachments).
