How to truncate a string in groovy?

Question

How to truncate string in groovy?

I used:

def c = truncate("abscd adfa dasfds ghisgirs fsdfgf", 10) 

but getting error.

The Groovy community has added a take() method which can be used for easy and safe string truncation.

Examples:

"abscd adfa dasfds ghisgirs fsdfgf".take(10)  //"abscd adfa" "It's groovy, man".take(4)      //"It's" "It's groovy, man".take(10000)  //"It's groovy, man" (no exception thrown) 

There's also a corresponding drop() method:

"It's groovy, man".drop(15)         //"n" "It's groovy, man".drop(5).take(6)  //"groovy" 

Both take() and drop() are relative to the start of the string, as in "take from the front" and "drop from the front".

Online Groovy console to run the examples:
