Remove letter at specific position in Ring !

[MOHANNAD ALDULAIMI]

Hello Ring Family.

I  have this code and I want to modify a specific letter or char. by reference ,

Yes I can remove it using substr function but I wanted to know if it is posable to do this without using deep copy...

BTW : Another solution is to create new variable and add the string to it then make a deep copy of it to the first one.

take a look :

 

Best wishes...

Hello Mohannad,

number and string as basic types are always copied in Ring. However, because you are allowed to pass lists by reference, keeping strings you want to modify inside the list, gives you possibility to modify strings without copy. Sadly, basic type rule applies for list items too, so entire list must be referenced.

Greetings,

Ilir

aList = ["Hello-World"]

fastSubStr(aList,1,"-"," ")

? aList[1]

aList = ["Hello- -World"]

fastSubStr(aList,1,"-","")

? aList[1]

func fastSubStr(aList,index,char,replace)
/* No copy case */
if replace
for ch in aList[index]
if ch = char
ch = replace
ok
next
/* Deep copy case */
else
aList[index] = substr(aList[index],char,replace);
ok

Hello Muhannad,

Here is the Softanza approach in enabling you de modify strings (or any other type) by reference or by copy :

1. You create the object, say a stzString("R I N G")
2. You use Replace(" ", "-") on that object, and its value is modified by reference
3. You take a copy() from it and modify the copy, while the original string stays unmodified

Here is a snapshot of you case solved this way in SoftanzaLib:

PS: SoftanzaLib is still under testing.

All the best,

Mansour

Hello Mansour, Ilir 

I had this code, it was perfect for this situation ..

But is it acceptable for different applications (console ,web ,GUI)?

Best wishes...

Hello Mohannad,

Ring runs trough VM, so it is acceptable. There is no Ring to some other language translation yet (to say something cant' work: eval for example).

Mansour, very nice example in Softanaza. May I kindly ask you to stop posting all of these cool samples until the library becomes available? Just kidding of course, but the anticipation is killing me over here! :D

Cheers, 

ON

Out of curiosity, when will Softanza become available? 🤓

[Mansour Ayouni]

Hello ON and Gary,

Be assures, it's a matter of few months not years :D

Hopefully your patience will be rewarded by all the beauty you will enjoy in using the library.

Seriously, the main cause of delay was that I decided to challenge Softanza and use it (partially) in some of my real-world projects. The feedback I got helped me strengthen many aspects and validate many assumptions.

Thank you very much!

Mansour
