Ruby Naming Rules (@,@@,$)

[SerraAvenger]

How good are you with the ruby naming rules?
I tend forgetting them, hence all my globals are constant and stuff like that : )

I have to look them up every time I start my IDE xD I should really write them down somewhere.

What are your experiences with these naming rules?

 

[Hakeem]

It's not that overwhelming is it?

@instance
@@class
$global
Constant
normal

 

[Shados]

*

@instance_variable
@@class_variable
CONSTANT_VARIABLE
Class/ModuleName
local_variable

Classes and Modules, despite being constants, are named differently so as to make them easily differentiable.

You also forgot the rules on word separators, Hakeem. And yeah, they're not particularly hard to remember and adhere to.

 

[Hakeem]

Naming conventions are more like guidelines anyway.

 

[Shados]

They're exactly what they claim to be; conventions. However, conforming to programming naming conventions serves a useful purpose in that it generally increases code readability and decreases comprehension time.

 

[SerraAvenger]

In ruby, these are not just conventions. Your interpreter will complain if you try to do

A = 1
A = 2

^^

And while these are not that many, I still have to look them up every now and then.

Edit: Btw, if they are so easy to remember, why did our dear fellow Hakeem then forget about 40% of the rules when posting them ; )

 

[Hakeem]

What I posted are the strict rules that the parser adheres to. Shados provided the conventions.

thanks a lot for the clearification : )
As you see, I'm just overwhelmed by the beauty of the language while I'm still learning quite a lot ^^
