Operation request: Operate only on a section of the input

[n1474335]

Summary

A Flow Control operation to specify that the subsequent operation is only run on a subsection of the input, rather than the whole thing.

The subsection could be defined using a regular expression or offsets.

Instead of the subsection only applying to one operation, the existing 'Merge' operation could be used to define the point at which the entire input is processed again.

Example

Input

123test456

Recipe

Subsection (or some other more suitable name)
    Section (regex): .{3}([a-z]+).{3}
To Braille

Output

123⠞⠑⠎⠞456

Hi,

I'm not sure how to use this Recipe to, say, extract numbers from some lines of input and sum them up. Am I misunderstanding how this is meant to work?

https://gchq.github.io/CyberChef/#recipe=Subsection('%5ENum%20%3D%20(%5C%5Cd%2B)',true,true,false)Merge()Sum('Line%20feed')&input=TnVtID0gMTAKTnVtID0gMjAKTnVtID0gMzAK

Thanks!

Hello,

For the functionality you are looking for I have come up with the following solution:

https://gchq.github.io/CyberChef/#recipe=Regular_expression('User%20defined','%5C%5Cd%2B',true,true,false,false,false,false,'List%20matches')Sum('Line%20feed')&input=TnVtID0gMTAKTnVtID0gMjAKTnVtID0gMzAK
