Template Notes

Fastfood uses the Jinja2 templating engine with 2 modifications.

qstring()

There is a helper method added to jinja2 for fastfood called qstring, it takes in an argument and if that argument does not match a Chef node attributes (node['mysomething'] | node.chef_environment) it will wrap that argument in a string otherwise it just returns the argument.

qstring("node['mysomething']")

renders as

node['mysomething']

and

qstring("mynonchefstr")

renders as

"mynonchefstr"

jinja variable

Because the traditional jinja2 variable start and end strings can conflict with Ruby code fastfood uses '|{' and '}|' to represent a jinja2 variable.

|{ options['name'] }|
