Regex folder match not working with script

Script Method panel not working. I'm just trying to get it to return the year part using a simple regex pattern. But it returns a string concantenated with original string separated by two ".." dots. Can't figure out what i'm doing wrong?

==================
Original folder name (other folders follow same format):
==================
2015.11.20 - Orlando - Downtown - E Colonial Dr

==================
Using only one Script Method:
==================
var patt = /\d{4}[.]/;
var yearPart = patt.exec(item.newBasename);

return yearPart;

================
Output:
================
2015..20 - Orlando - Downtown - E Colonial Dr

This output looks wrong to me. I was expecting to see only 2015 and not what appeared. What am I missing?

Also, I don't know if this is related but weirdly whenever I try to add a new script block it remembers the last script that had been used. Is there some way to turn this off?

Well, for the sake of correcting your script, here it is:

var patt = /(\d{4}).+/;
var yearPart = patt.exec(item.newBasename);
return yearPart[1];

You needed to capture a group in your expression with () and use it with an array position on the result array yearPart[1]. Also, [.] means matching one character, of any kind. .+ means matching any characters, so it would fit better with what you are trying to achieve.

But quite honestly, this wasn't needed to be done with a script, could've very well be done with "remove" method, from position 5 onward, or "replace" with the same kind of regex..

hope that helps,
cheers

Thanks for the Regex clarification. It really helped. What I needed was to return the Year and the period.

===============
Regex Fixed
===============
/(\d{4})\./

===============
Expected Return
===============
2015.

===============
Actual Return
===============
2015..20 - Orlando - Downtown - E Colonial Dr

As you can see from this screen capture. All my returns are messed up.

As a test to see if this is a program bug, I changed the script to just return "hello" and the same error appears. Is there some sort of setting I need change or clear the internal program cache?

I must admit, its an interesting bug...

Only affect folders... works fine on files.

To go around it, put your script method to "name and extension"

cheers
