Code style, naming conventions

I am seeing common variable naming patterns but can't find a style guide. Can someone please provide best practices?

Some examples:

oView = Assuming o stands for object?

$url = Not sure what $ means

cStr = Assuming c stands for character? Is this for all string variables?

nFields = Assuming n stands for number? Used for all ints?

aResultRow = Assuming a stands for array even though Ring calls them lists?

And some function names in the Softanza library that use an uppercase Q: and a variable name that begins with @. Are these specific to this library or universal?

StzBinaryNumberQ, StzStringQ = Not sure what Q means

@cBinaryNumber = Not sure what @ means when used in a variable name

Are there any others? For example, constants? In other languages constants may be defined as CONSTANT = "VALUE".

Thank you

My understanding of variables naming convention in Ring is close to yours:
  • o prefix for objects
  • $ prefix for global variables
  • c prefix for strings
  • n prefix for numbers (integer or double)
  • a prefix for lists
Mahmoud is the authority for Ring so let's wait for his feedback.

Hello Mounir

I agree with you :D
In practice I am using o, c, n & a in the start of the variable name like (oObject, cString, nNumber, aList)
For constants I use C_ in the start of the name and write the constant using UPPER CASE like C_BUTTONWIDTH = 200

Using $ before global variable and @ before object attribute is possible and is similar to Ruby
I don't use global variables in large projects as much as I can
Also, Ring have (load package) command which load libraries in separate global scope, This avoid conflicts in global variable names
So, Sometimes I use $ before the global variable name, but in most cases I don't do that.

Ring as a language encourage freedom (Any Style + Any Programming Paradigm + Any platform)
So, what is more important is selecting a specific style for the project. A style that is suitable for the developers who are developing this project

Hello Outnull,

Softanza embraces the same naming conventions of Ring (c for strings, n for numbers, a for lists, and o for objects), and adds some specific ones...

Hence, @ is used for object attributes, and Q is used as a prefix to any function, taking the name of a Softanza object, to return that object for further processing.

So, for example, instead of writing:

o1 = new stzString("softanza")
? o1.Content()
#--> "S O F T A N Z A"

We can just say it in one line like this:
? StzStringQ("softanza").UppercaseQ().SpacifyQ().Content() 
#--> "S O F T A N Z A"

As you can see, the Q puts the object in a "Queue" for fluently acting on the object while interrupting our train of thoughts.

Hello Mounir, Mahmoud, and Mansour 

You were just the 3 I was hoping to hear from on this question. Thank you for the explanations! :)

Mansour, the more I learn about your Softanza library the more intrigued I become. Appreciate that clear example of how Q is used.
