Basic operation on char...

njeremy2

Hello everyone !
I have a stupid question but I can't find the solution...
I would like to retrieve a string until " " (space) from description of component.

%(#008000)[MY example :
Definition : Cube
Description : 755480RED That's my cube]

755480RED is a reference of the cube and "That's my cube" the real description.
I just need to retrieve the reference include in the description.

description = Sketchup.active_model.description
Sketchup.active_model.entities.each do |entities|
@tab << entities
	@tab.each do |element|
		UI.messagebox "#{element.description}".to_i
	end #end TAB.EACH
end #model.each

Here,
when I put : UI.messagebox "#{element.description}" I have the complete description.
when I put : UI.messagebox "#{element.description}".to_i I have only the first number (it works only if the reference are numbers only)

What I need is to put a condition which is:
Retrive the description until you found " " but I don't know how to do that.

Someone can help me ?

element.description.split(' ')[0]

Reference: String#split

Btw, did you create the component? Is it intended for the user to read that reference code?
If not, then you might want to store it in an attribute:

Entity#get_attribute: https://developers.google.com/sketchup/docs/ourdoc/entity#get_attribute
Entity#set_attribute: https://developers.google.com/sketchup/docs/ourdoc/entity#set_attribute
class AttributeDictionary: https://developers.google.com/sketchup/docs/ourdoc/attributedictionary
class AttributeDictionaries: https://developers.google.com/sketchup/docs/ourdoc/attributedictionaries

Yeahhh !! thanks thomthom !!

I searched in french tutorials, that's why I didn't found anything !! lol

no no ! it's ok !

Components are already create when I put components in design I launch my plug test.
My plugin search all components and then I ask it to display each references include in their description

Sorry I don't understand the first time I read your post...
I can use attributes but I see in AUTOMATIC Sketchup.pdf that's attributes cannot be stored when you save a component (I understand that)

And put the reference into the description was for me the easiest solution (I hope, if someone has a better solution, tell me).

In that way, I'm sure the reference is shared when I sent a component to my database

If you store attributes with the definition then you can export the component with the attributes.

Example:

componentinstance.definition.set_attribute('MyTest', 'Foo', 'Bar')

Export component

New model

Import exported model

componentinstance.definition.get_attribute('MyTest', 'Foo')
( returns 'Bar' )

njeremy2

hmmmm, well...

With that, you can add an attribute called "reference" for all components and set attribute then ?

So if I do like that : componentinstance.definition.set_attribute('Reference', '755480RED', 'Valuedefaultif 755480RED doesnt exist')

That would work ?

And to list all references, how should I do ?
componentinstance.definition.set_attribute('Reference') ?

Read the API docs again.

set_attribute takes three arguments. The third one is the value.

entity.set_attribute( 'DictionaryName', 'Key', 'Value' )
entity.get_attribute( 'DictionaryName', 'Key' )

So, if you do something like to to add a reference ID:
entity.set_attribute( 'nJeremy2', 'Reference', referenceID )

You can list all definitions with a reference set like so:

<span class="syntaxdefault"><br />for definition in Sketchup</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">active_model</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">definitions<br />  next if definition</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">image</span><span class="syntaxkeyword">?<br /></span><span class="syntaxdefault">  next if definition</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">group</span><span class="syntaxkeyword">?<br /></span><span class="syntaxdefault">  referenceID </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> entity</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">get_attribute</span><span class="syntaxkeyword">(</span><span class="syntaxdefault"> </span><span class="syntaxstring">'nJeremy2'</span><span class="syntaxkeyword">,</span><span class="syntaxdefault"> </span><span class="syntaxstring">'Reference'</span><span class="syntaxdefault"> </span><span class="syntaxkeyword">)<br /></span><span class="syntaxdefault">  next if referenceID</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">nil</span><span class="syntaxkeyword">?<br /></span><span class="syntaxdefault">  </span><span class="syntaxcomment"># Do something to the definition here...<br /></span><span class="syntaxdefault">end<br /></span>

yeah ok !
I will try but the result is not guarantee

njeremy2

my solution by putting the reference in description work, it isn't good programming but it works lol

thank you thom !

What if your user accidentally modify the description? Or some other plugin the user has install modifies it?

right...

But I try to use attributes, but I cannot do it right

thomthom

What is not working right?
Do you have a sample code?

When assigning an attribute to the definition the attribute is stored whenever you export - it works fine. But if it doesn't work for you then it's probably something in your code that isn't quite right.

I have nothing at home, tomorrow I'll show you what I need to do with that (with screenshots)

For this example I put a tree and a Blue cube.
The tree has no description and the Cube has code reference then the real description after "b755480 BLABLABLA".
Then I create a groupe with the 2 objects called "Tree+cube"

Now I export all information with my plugin :

then I export all information in CSV File :
