I’ve been working with modules and classes for a while now but I don’t know that I truly understand all of the finer points on how to do specific things. For instance I’m nesting classes inside of modules and those modules inside of other modules to carefully control the namespace for example: mod…

Now I want to create a global module that the instance variables can be accessed from my other two modules: module Medeek_Engineering_Inc_Extensions module MedeekFoundationPlugin class MedeekMethods class << self def global_settings @globalvar1 = "something" @globalvar2 = "something" end …

[image] medeek: and then those variables created within the global_settings method be accessible from inside of the other two modules. I’m not entirely sure I understand exactly what you are looking to do there. You want to be able to use @globalvar1 directly from another module? As for acce…

Essentially yes, and again I may be going about this completely wrong. I would like to keep my various parts of the Foundation plugin separate (for namespace and other reasons). So I’ve organized them into different modules as shown above. However, I would like to maintain only one global setting…

In this regard I’m also trying to better understand if using a Mix-in module might be the way to handle this sort of thing, and I’m a little unsure on how the syntax for the global settings module should be constructed.

[image] medeek: module Medeek_Engineering_Inc_Extensions module MedeekFoundationPlugin module Stemwalls class MedeekMethods class << self def some_method_for_stemwalls end end end end end end You don’t really need such a deep nesting…

Which also brings up another question I’ve often had. Should the global settings be loaded up when the plugin is loaded (ie. SketchUp startup) or should I only load them up when the user initiates some command with the plugin. I guess I’m not wanting to load a bunch of stuff into the memory if it…

Sketchup.read_default is very fast. I used to have my own settings class that stored everything in a single registry key to avoid clutter. It had to parse it, handle parsing errors, cache it and write back before SketchUp was closed. All too complicated for little benefit. With some tricks (by thom…

Okay, so you are saying its not bad to load up your global settings at startup. I’ve never noticed a slowdown so it is fast but I’m just worried about all of those variable/constant definitions floating around doing nothing, for my Wall plugin the number has really grown. The last thing I want to …

I meant it is fast enough to be called multiple times on demand (instead of building a huge caching mechanism around).

I’ve tried several times to get you to do it the easy way … you don’t need a class, that just confuses things. [Template] Multi-File, Multi-Class with SharedConstants Mixin Otherwise just read the “ol’ Pick Axe” book’s chapter on Mixin modules.
