Is there any way to url decode variable on Freemarker?

Question

I'm looking for a way to url decode a string variable on Freemarker.

For example, consider the following string: attr=hello+world%3F . Expected result: hello world?

Any simple way to get this result? somewhat like ${attr?urlDecode}? I could not find anything online.

Thanks.

As mentioned above, FreeMarker only has built in support for URL encoding, not decoding. You can however solve this by creating your own directive for URI-decoding.

Something like this: https://gist.github.com/lazee/285d206470fb6076d262

Here is a small test class that shows you how you can add the directive as a shared variable, and how to use it in a template: https://gist.github.com/lazee/f5c524b3c7bebf68955e

Use this tester instead : https://gist.github.com/lazee/1307b7b05ea52f793db7 . Had a leftover of some other test code in the previous Tester.java – Jakob Vad Nielsen Aug 18 '15 at 19:31
I haven't tested it yet. But it looks promising. Thanks! – Amir Aug 19 '15 at 14:01

There's no such function built in (2.3.23).

In what scenario is it needed?
