String lenth limit

Rails
#1

Hi,

I’ve seen some time ago a function which, given a string like “this is a
very long string” would return , for example limitin it to 10 chars
“this
is a…” , but I can’t remember where… I’ve searched throwth the
apis
of rails and ruby itself and I can’t find it.

Thanks everybody…

Slice? or Split?

mmm… neither of both…

I’m talking of something like this:

“my very long string again”.funky_function(10) ==> “my very lo…”

I know it’s very easy to implement… I think I’ll end going that way.

Thanks

Sorry, its a view helper. So it is available in all views.

str = “This is a long string This is a long string This is a long
string This is a long string This is a long string”

truncate str, 20

That will truncate the string to 20 chars and add a ‘…’ to the end.
