How do I split text strings in different places using smart values?

Callum Carlile _Automation Consultants_

Hi all, I've got a string in a text field which looks something like

A001683R001S002L004

Using Jira automation (Cloud), I'd like to use smart values to split this reference up into sections and populate some hidden custom fields with these sections, so it would look like:

A001683 (custom field A) - first 7 characters
R001 (custom field - characters 8-11
S002 (custom field C) - characters 12-15
L004 (custom field D) - characters 16-19

I assume I need to use the {{issue.field.split(... function but I'm not sure how to format this to split the string based off the number of characters, rather than by a (" ") or a (".") etc.

I can do the custom field edits and setting rule variables, it's just this splitting part which I'm stuck on. Any ideas would be much appreciated!

@Callum Carlile _Automation Consultants_ if the text string is always a fixed length and the character position remain the same, I'd use the .substring(start, end) function.

{{issue.field.substring(0,7)}}
{{issue.field.substring(7,11)}}
...

Thanks @Gareth Cantrell this is exactly what I was looking for - works like a charm!!

Hi @Gareth Cantrell sorry to bring back an old thread but I am trying to perform this task except the strings are not always fixed length. They are comma separated (for example Label1,Label2,Label3) and could be random length labels. Is there a way to do this if you don't know the exact length of each value that will be returned?

Hi @David Washburn ,

What you want for that is the .split() function.

The below code will split the string into a list using a comma as the separator:

{{issue.fieldX.split(“,”)}}

You can use the list.get(index) function to get the item at a specific index.

E.g.

{{issue.fieldX.split(“,”).get(1)}}

will retrieve the 2nd value from the list.
