Setting the save path for files ???

artmusicstudio

hi,
here is a small one :

retrieve file path works:


model = Sketchup.active_model
@local_user_path = model.path
puts @local_user_path
end

but how can write back the path, when it was changed by save-operations from my ruby, so that
autobackup writes its files to the original file directory and not to the plugin folder ??

no "set_path" function in the model class found....

thanx stan

` @old_path = model.path
Sketchup.send_action("saveDocument:")

make changes here

model.save( @new_path )

Sketchup.open_file( @old_path )`

Note that on the Mac, there will now be 2 document windows open.

hi dan,
yes, this is for saving sketchup models from the ruby, right?

but skp seems to use the last use directory for saving ( in my case MY save function for my ruby parameters) of further files, like autobackup. they all appear now in the ruby directory.
so can i define somewhere the system variable for the save directory, whithout saving a model file myself ?

means, restoring the value of model path from 'old path' by setting a value only?

You need to learn the standard Ruby classes File and Dir.

Current Working System directory:
Dir.getwd

NEVER trust that it is pointing where you wish, because any script can change it.
BE NICE .. so SAVE and RESTORE it if you change it, when your done.

prevdir = Dir.getwd
Dir.chdir( @new_path )
#
### save files to new dir with only filespecs
#
### Restore previous working directory;
Dir.chdir( prevdir )

It is initially set to the User's HOME directory (%USERPROFILE% on Windows.)
On MAC: ENV["HOME"]
On Win: ENV["USERPROFILE"]

Under Ruby "~/" will only expand to the User's root dir, IF ENV["HOME"] is defined.
so, on Windows...
ENV["HOME"]=ENV["USERPROFILE"] unless ENV["HOME"]

Other info:

Current models full pathname:
model.path

Current models directory:
File.dirname( model.path )

Current model's filespec:
File.basename( model.path )

Current model's filename:
model.title

Current model's file extension:
File.extname( model.path )

Joining a new path with a old filespec:
File.join( @new_path, File.basename( model.path ) )

hi dan,
that's exactly, what i ment.
i want to restore the user file path after my ruby finished it's job.
perfect!

thank you very much, also for the other system variables, very useful for future development.
