Instructor content

bentleykfrog

seems like the response is relative to the help directory on pc

writing the following brings up the eraser tool

def getInstructorContentDirectory
  return "\\21019\\"
end

so looks like relative paths it is

bentleykfrog

hmmmm the following works well on pc too

def getInstructorContentDirectory
  return "../../../../Tools/etc/instructor/"
end

Woohoo! That totally does it. that works in 7.1 also, I did not test anything earlier than that. Here is my code that uses it and points to a directory inside the plugins folder:

` class Clf_instructor

def getInstructorContentDirectory
return "..\..\..\..\Plugins\doc\"
end
end

Sketchup.active_model.select_tool Clf_instructor.new`

(that is just a snippet I was running from the webconsole, not actually part of a full file).

Thanks for coming back and posting that,

Chris

The instructor works???
Nice find!

This'll be useful for Bezier Surface.

Another example of how the API docs (and a poorly written example,) have thrown us all off course for months!

It does smell like a bug though. It doesn't sound right that they intended people to add custom Instructor content to the SU Instructor content folder.

Its unusual that they document absolute paths but only go with relative paths, not that relative paths are bad by any means.

It's awkward though. I run my plugins I develop from custom locations because I use Mercurial for revision control. So providing a path to a custom location from the hard coded instructor folder isn't ideal. (does it even work across drive letters?)
And because some OSX users put their plugins in the user folder instead of the default, one can never rely to plugins to be at a fixed relative path.

Does anyone know how to find out how many slashes and dots are needed at certain end user comp ("..\..\..\..\"). I mean if someone has installed sketchup in a custom subdirectory it is necessary to add/remove one of "..\" I guess.

It should work cross platform?

TIG

My method 2 posts before this uses the absolute path of the calling script to construct a relative path to the important folders ?
How do we allow for MAC users with their plugins 'in the wrong place' OR even my uni students who have to install their PC 3rd party scripts in their persona H:/Sketchup_Plugins/ folder, with a script added by their IT guys in the main Plugins to add that path to their $LOAD_PATH array... Would these still work with my idea ??

thomthom

Can we get the path of the resource folder?
If so, then we could add ../ back references until we're back at the root, then apply the absolute path.
Though, how does one deal with different drive letters under Windows?

Ah - didn't see bentleykfrog's reply.

plugin_folder = Sketchup.find_support_file test_file.html, "Tools/My Plugin/"
This is not reliable way to find the location of where your plugin is installed. This is what breaks under OSX when users place them in incorrect locations - and it will also throw errors is people install plugins to custom locations, like TIG and I do.

To get the path of your plugin:
plugin_path = File.dirname( __FILE__ )

To get SU Plugins path:
su_plugin_folder = Sketchup.find_support_file( 'Plugins' )

We can get the Resource folder by using:
plugin_folder = Sketchup.find_support_file( 'Resources' )

But then there's a folder named after the current locale...

I think that because its relative to [sketchup folder]/Resources/[language]/helpcontent/tool/ that it shouldn't matter where sketchup is installed, as this will be constant. The parent directory "..\" folder just goes back through tool -> helpcontent -> [language] -> resources to get you to the base [sketchup folder].

You're right this is a huge issue. I'm guessing that on OSX this path will be relative to the main library folder (ie. [primary hard drive]/Library/Application Support/[sketchup folder]/Sketchup/Resources/[language]/helpcontent/tool/). So maybe you can do some comparison between Sketchup.find_support_file "[some_file].html", "Tools/[your_plugin]/" and the main library location, like this:

def getInstructorContentDirectory
  plugin_folder = Sketchup.find_support_file test_file.html, "Tools/My Plugin/"
  plugin_folder = plugin_folder.split("test_file.html")
  plugin_folder_array = plugin_folder[0].split("/")
  if(plugin_folder_array[1] == "Library")
    #so the plugin/tool is stored in the main library
    return "../../../../Tools/My Plugin/Instructor/"
  elsif (plugin_folder_array[1] == "Program Files" || plugin_folder_array[1] == "Program Files (x86)")
    #the operating system is PC, so only 1 location for tools/plugins
    #there's probably a better way to do this
    return "../../../../Tools/My Plugin/Instructor/"
  else
    #not sure about this, especially since it could be traversing drives
    return "../../../../../../../../../"+plugin_folder+"Instructor/"
  end
end

I'm not sure about the OSX support, but I'll check after I'm finished with my work on the PC.

What do you guys think?

So you have to know the drive letter of the file you are testing and then cludge that into the tested path...
It will then work across drives on a network - unsure of a MAC though ???

thomthom

But, does that work for the instructor?
