Error in IsAlpha() and IsAlnum() functions?

[Mansour Ayouni]

Hello Mahmoud,

The functions seem to return incorrect output:

Here is the code to copy-paste and test it:

? isAlpha("Ring")
#--> TRUE

 

? isAlnum("Ring 1.20")
#!--> FALSE
#~> Should be TRUE

 

? isAlpha("محمود")
#!--> FALSE
#~> Should be TRUE

Best,

Mansour

Hello again,

After rechecking ? isAlnum("Ring 1.20"), it's normal that it returns FALSE because " " and "." chars are neither letters nor numbers.

Hence, the problem remains only in detecting non-latin letters by the isAlpha() function (like Arabic in the example).

Best,

Mansour

Hello Mansour

>> "Hence, the problem remains only in detecting non-latin letters by the isAlpha() function (like Arabic in the example)."

This is the expected behaviour

These functions are wrappers around the standard C functions

Ring is designed to be lightweight, where Unicode or Arabic support could be achieved through extensions/library

As you already know through RingQt

Hello Mahmoud,

Thank you for your answer.

Implemented in Softanza in the form of two equivalent functions @IsAlpha() and @IsAlnum(), @ being used to avoid conflicting names with the standard Ring functions:

Best regards,

Mansour
