tempio's Issues

non-file output

I think it would be a nice addition, if tempio could output the resulting template (instead of writing to a file), in case no -output flag was specified.

This could be helpful in cases to render content that is not stored on disk (but, for example, send to a webservice of some kind).

It is more of an suggestion, not a real issue. Maybe I get to it myself one day. No rush at all.

Use 2 dimensional lists

Hi is it possible to use 2 dimensional lists with tempio?

For example:

"logins": 
    [
      { "username": "user1", "password": "1234" },
      { "username": "user2", "password": "5678" }
    ]

And then insert all usernames to a template:
valid users = /{{ .logins.username | join "," }}/
