Retrieve size sketchup file using ruby

glro

The idea is to prevent sketchup from crashing when a plugin is called on a model the size of which is too big for the computer capacity

by showing an error message before the plugin is effectively launched

i didn't find anything in "model info" SU ruby API concerning the file size

is there a way using ruby?

The File.size( filePath ) returns the specified file's size in bytes.
So if your code gets the SKP model.path and it's not empty, then you can get the size of that SKP...
Then do what you want with it...

model = Sketchup.active_model
path = model.path
unless path.empty?
  size = File.size( path )
  UI.messagebox("This SKP is #{size} bytes !")
  ### or whatever...
end

glro

OK

i didn't find this information in
http://www.sketchup.com/intl/en/developer/docs/methods.php
nor
http://www.sketchup.com/intl/en/developer/docs/classes.php

Thank you, your code works

As long as the path doesn't contains "é" or "è", or characters like that

Using french and meters while programming sketchup, makes it more difficult...

Impossible to detect problematic characters in a path, since ruby answers "Run aborted (error has occurred)" and stops...

The problems with accents in File paths and SketchUp's current Ruby on PCs are well know.
It is a 'PITA'

Until a better version of Ruby is used by SketchUp [ ] for now you could try encoding the path - but it is an unreliable pain...

### get 'path'
if $KCODE=="UTF8" ### what is yours ?
    begin
      upath = path.unpack("U*").map{|c| c.chr }.join
    rescue
      upath = path
    end
  end#if
end
### Then do 'File' operation on the encoded string...
exist = File.exist?( upath )
size = File.size( upath )
### etc

glro

Yes, it is UTF8

For now, i shall use the code like this

begin
unless path.empty?
  size = File.size( path )
  UI.messagebox("This SKP is #{size} bytes !")
  ### or whatever...
end
rescue
UI.messagebox "problematic characters in the file path"
return
end

thank you

Those docs only cover the SketchUp API, refer to the Ruby docs for core Ruby features: http://www.ruby-doc.org/core-1.8.6/index.html

I am not a professional programmer, and sometimes, i even surprise myself when i get a result from the code i just wrote

there is intelligence in the code itself

Maybe that's why i enjoy so much writing code

Next time i don't find something in SU API, i'll look for it in Ruby doc

Thank you
