When calling a mixin in Jade, what's the difference between "+" and mixin keyword?
keyword, mixins, node.js, pug, templating
Solution
Yes, it appears so. If you look at `lib/lexer.js` in the `Call mixin` section, you can see that terms beginning with a `+` get tokenized with type `call`. Later in `lib/parser.js` the `call` token causes `parseCall` to create a new mixin invocation node.
Furthermore the commit was made with with the comment:
Added preliminary mixin block support and the new + mixin invocation syntax.
Problem
The docmentation tells us to call a mixin by prepending the keyword `mixin` to the actual mixin. ``` .bar mixin foo(arguments) ``` But on different places I saw people calling a mixin by prepending a plus (+) sign, like: ``` .bar +foo(arguments) ``` Could someone please explain the difference since the documentation does not seem to show it. I tried both examples and both seemed to work. Is `+` just a shorthand?
