Incremental rename bunch of components

[dedmin]

Is there a plugin to incremental rename bunch of components:

name#N

If it doesnt exist itd be pretty easy to make.

Just to clarify, is the "name" in "name#N" constant?

And DefinitionList.unique_name does most of the job:

@unknownuser said:

The unique_name is used to generate a unique name for a definition based on a base_name string. For example, a base_name of "Joe" might return "Joe #2"

Iterate the selected instances, collect the definitions.
Iterate the definitions naming them by what DefinitionList.unique_name.
Bob's your uncle.

Yes. Something like this - cab#1, cab#2 ...

Copy/paste this code into a file called componentrenamer.rb in the Plugins folder.
To run it you type componentrenamer "NewName#1" in the Ruby Console to change the name of selected component-instances' definitions to NewName#1, NewName#2, NewName#3 etc...
Note: starting with ' NewName' increments the second one to ' NewName#1'

def componentrenamer(newname)
  model=Sketchup.active_model
  ss=model.selection
  defs=[]
  ss.each{|e|defs << e.definition if e.class==Sketchup;;ComponentInstance}
  defs.uniq.each{|d|d.name=model.definitions.unique_name(newname)}
end#def

Just perfect!!!!

Here it is. Thanks TIG!!!

componentrenamer.rb

Nice!

I'm guessing the # sign is part of the internal SketchUp API? #s cause some problems with how I use models externally. I looked at the (dang simple) code and didn't see any immediate way to suppress the #.

This is for keeping all instances the same component, but using a different name, correct? It's not taking all instances and making them unique when renaming? (Similar to what happens when two components of the same name come in but are different -- the second one is named: name#1.)

To strip the # try adding an extra argument

def componentrenamer(newname,nnn=nil)
  model=Sketchup.active_model
  ss=model.selection
  defs=[]
  ss.each{|e|defs << e.definition if e.class==Sketchup;;ComponentInstance}
  defs.uniq.each{|d|
    unn=model.definitions.unique_name(newname)
    unn=unn.tr("#",nnn)if nnn
    d.name=unn
  }
end#def

The second string in the translation tr nnn can be anything you want - e.g. "-" or "_" ?
The usage now has an optional second argument to replace the # with something else
e.g. componentrenamer("NewName","_")
If you don't add it then the # remains unchanged...

Thanks TIG! I'll try it out (and learn a little more about SU Ruby)
