Pongo2

The PONGO2 Templating Plugin

• Pongo2 templates may be identified by a shebang on the first line (preferred method) or changing the file extension to home.pongo2.html. By default the operation of revel assumes just a .html extension for controller responses so it would make more sense to use the shebang

• Pongo2 templates can be set to be case sensitive by setting pongo2.tempate.caseinsensitive=false, default is not case sensitive. If case sensitivity is off the templates are compiled using lower case

• Currently the only functions built in are as follows:

  • field
  • radio
  • option
  • url
  • checkbox
  • append

  Samples implementation below

Details

pongo2 is the successor of pongo, a Django-syntax like templating-language.

Install/update using go get (no dependencies required by pongo2):

go get -u github.com/flosch/pongo2

Please use the issue tracker if you're encountering any problems with pongo2 or if you need help with implementing tags or filters (create a ticket!). If possible, please use playground to create a short test case on what's wrong and include the link to the snippet in your issue.

New: Try pongo2 out in the pongo2 playground.
