Official filter and tag add-ons for pongo2. Since this package uses 3rd-party-libraries, it's in its own package.

Install via go get -u github.com/flosch/pongo2-addons. All dependencies will be automatically fetched and installed.

Simply add the following import line after importing pongo2:

_ "github.com/flosch/pongo2-addons"

All additional filters/tags will be registered automatically.
