Trouble loading scripts outside Plugins directory

mgianzero

I'm trying to learn Ruby and stay a bit organized. So I wanted to place my personal ruby scripts under "Documents/Sketchup/Marc_Scripts" on my Mac. I tried following the Google Ruby API website and so I created a script called "myrubyscripts.rb" under the Sketchup Plugins directory. In it I put:

home = File.expand_path "-"
myrubyscripts = File.join home, "MyRubyScripts"
require_all("Documents/Sketchup/Marc_Scripts")

But it doesn't work. What am I doing wrong?

Hi Marc,

I think you need to use the full path to your plugins:


require 'sketchup'
require_all('/Users/YourUserName/Documents/SketchUp/Marc_Scripts')

You are not using your variable myrubyscripts for anything. Looks like you are passing only part of the path.
Use some puts to investigate the data you pass around when you experience unexpected problems. That way you can verify that the data you think you pass is what you actually pass.

The example assumes your script dir is a subdir of 'Plugins'.
It does not explain the "tricks" of having a dir elsewhere.

home = File.expand_path "-"
(1) the HOME shortcut is a tilde char "~" not a dash.
(2) You dont need a "home" var because it's already defined in the Environment Variable Hash on the Mac. To access it from Ruby use: ENV['HOME']
So... the following:

myrubyscripts = File.join home, "MyRubyScripts" require_all('Documents/Sketchup/Marc_Scripts')
..becomes:
require 'sketchup' myscripts = File.join(ENV['HOME'],'Documents/Sketchup/My_Scripts')
require_all( myscripts )

This is the equivalent of what Jim showed with a literal argument.

The drawback is you wind up with all the script entries in the $" array being long absolute paths. You could save memory space by stealing and modifying the code block within sketchup.rb::require_all, like so:


begin
  # require('sketchup') ## not needed
  myscripts = ENV['HOME']+'/Documents/Sketchup/My_Scripts'
  $;.push( myscripts ) # add to $LOAD_PATH array
  old_wd = Dir.getwd   # save old working dir
  wd = Dir.chdir( myscripts )
  rbfiles = Dir["*.{rb,rbs}"]
  rbfiles.each {|f|
    if f.split('.').last=='rbs'
      Sketchup.require( f )
    else
      require( f )
    end
  }
  Dir.chdir(old_wd) # restore old working dir
end

Thanks Dan. I think I'll stick with your simplified solution. Works perfectly!

Now I can keep my plugins separate from the ones I downloaded from other folks.
