Create file with accent in the path

Iltis

OK, I see the error in the Ruby Console (thank you for the tip) :

Error: #<Errno::ENOENT: No such file or directory - C:/Users/Tarzan/Documents/aiR-C2/MiniCut2d/Bibliothèque/test.f2xy>
...

I will try to catch it.

Iltis

OK, this code works on SU8 :

		  begin
		  File.open(filepath, "w"){ |file|
			...
		  }
		 	UI.messagebox("The file is here ;" + filepath)
		rescue
		 	UI.messagebox("Error, the file was not created. Be careful if you are using an older version of SketchUp, the full file path must not contain special or accented characters. The full file path you requested is " + filepath)
		 end

The "è" looks "Ã¨" in the messagebox, but the user know how to fix the problem.

I try to use it in SketchUp 2014, but I've got an error

Erreur de chargement du fichier faces2xy.rb
Error; #<SyntaxError; C;/Users/Tarzan/AppData/Roaming/SketchUp/SketchUp 2014/SketchUp/Plugins/faces2xy.rb;18; syntax error, unexpected ',', expecting ')'
		  filepath = UI.savepanel ("Export selected faces",nil,"*.f2xy")
C;/Users/Tarzan/AppData/Roaming/SketchUp/SketchUp 2014/SketchUp/Plugins/faces2xy.rb;18; Can't assign to nil
		  filepath = UI.savepanel ("Export selected faces",nil,"*.f2xy")
C;/Users/Tarzan/AppData/Roaming/SketchUp/SketchUp 2014/SketchUp/Plugins/faces2xy.rb;18; syntax error, unexpected ')', expecting ;; or '[' or '.'
		  filepath = UI.savepanel ("Export selected faces",nil,"*.f2xy")

Do you know how to fix this (in all SU versions...)?
Thanks,
Renaud

That's odd - if the string is UTF-8 encoded then it should look fine in SketchUp regardless.
Have you saved your RB files as UTF-8 without BOM?

I'm not sure, but I think it could be that space you have between the method name and the parentheses: filepath = UI.savepanel ("Export selected faces",nil,"*.f2xy")

But the error could be cascading some elsewhere... hard to tell without knowing the source code.

Btw, it's recommended not to catch all exceptions, but only the ones you expect.

Bingo! 2/2. It works fine now. Is "UTF-8 without BOM" the best to use? (Default value?)
Thank you for the quick answer!
I will see how to catch only the file exception.

Iltis

Mhh, the error is

Error; #<Errno;;ENOENT; No such file or directory - C;/Users/Tarzan/Documents/aiR-C2/MiniCut2d/Bibliothèque/test.f2xy>

I don't understand how to only catch this type of exception... (not in the "Ruby Exception Hierarchy"). I'll see this later.

I recommend that because without the BOM you can load the file in Ruby 1.8. With the BOM Ruby 1.8 will not load it.

You should be able to catch Errno::ENOENT - it's a class inherited form StandardError.

Errno::ENOENT.ancestors [Errno::ENOENT, SystemCallError, StandardError, Exception, Object, PP::ObjectMixin, JSON::Ext::Generator::GeneratorMethods::Object, Kernel, BasicObject]

Though, it might be system dependant... Maybe catching SystemCallError is a good one to catch for these types of errors.

Iltis

OK, thank you.

Like this:

  begin
    File.open(filepath, "w"){ |file|
      #...
    }
    UI.messagebox("The file is here ;" + filepath)
  rescue SystemCallError => e
    if e.message =~ /(No such file or directory)/
      UI.messagebox("Error, the file was not created. Be careful if you are using an older version of SketchUp, the full file path must not contain special or accented characters. The full file path you requested is " + filepath)
    else
      fail() #re-raise the last exception
    end
  end

Iltis

Nice, thank you Dan!

fail() #re-raise the last exception

Never seen that method used before. Is that different from just calling raise?

raise() is an alias for fail()
See the doc on the Kernel module:
http://www.ruby-doc.org/core-1.8.6/Kernel.html#method-i-fail

The best practices guides I have read, suggest that fail be used instead of raise, for readability, I suppose. But I really did not understand the logic in the guide. (I think it was something like "raise" has more meanings as a verb than "fail" ?)
