@rotexdev You can send new pull request with change which @bakert had suggested. We would definitely want to keep compatibility for all browsers and CommonJS environments.

@rotexdev Thanks for the pull request. We also would like to maintain compatibility of jSmart with original Smarty template engine which does not has trim modifier.

If you want to have trim modifier specific to your project then you can find documentation for that here.
