Pass variable from content to layout in Nanoc using Slim

229 Views Asked by Daniel Salazar At 11 December 2018 at 22:11

I basically want to know the easiest way to pass a ruby variable from a content page to its layout using Nanoc and Slim. I am thinking of something like this:

content/content.slim:

---
title: Writeups
layout: /layout.slim
---
- age = get_age

layout/layout.slim:

doctype html
  html
    head
      == yield
      p I am #{@item[:title]} and am #{@item[:age]} years old

I know how to access values via frontmatter, but frontmatter values are fixed and what I want is a ruby function to find that value for me.

Nanoc provides a capturing helper, which makes it possible to “capture” content in one place and use it somewhere else.

content/content.slim:

---
title: Mister Tree
---

p Hello there!

- content_for :age
  | hundreds of years

layout/layout.slim:

doctype html
html
  body
    == yield
    p I am #{@item[:title]} and am #{content_for(@item, :age)} years old

lib/default.rb (or any file in lib/ of your choosing):

use_helper Nanoc::Helpers::Capturing

This generates the following output:

<!DOCTYPE html>
<html>
  <body>
    <p>Hello there!</p>
    <p>I am Mister Tree and am hundreds of years years old</p>
  </body>
</html>
