Remove suffix of layer name script

[mariap81355074]

Hi everyone,

I've tried googling but haven't found what I need; I just need a simple script that will remove the last 4 characters of the active layer name.

Because I use another script to import an image file and it retains the extention .png in the layer name and I just want to remove it, but without changing any other part of the layer name.

Thanks so much 🙂

Deletes a period and the next three characters at the end.

app.activeDocument.activeLayer.name = app.activeDocument.activeLayer.name.replace(/\....$/, "");

Works perfectly, thank you so much 🙂 I really appreciate your help 😄

If there is a chance that the filename extension may be 2, 3 or 4 (or even 1 or 5+) characters long, then a more robust/bullet-proof option would be:

.replace(/\.[^\.]+$/, '');

Still trying to wrap my head around regex. I still use this method for stripping off an extension:

.split('.')[0];
