{% comment %} The following is a breathtaking work of stunning beauty. It make build time O(n^2) in the number of docs pages. It uses nested loops and tons of state variables. It uses absolutely no data abstraction, not even records. It is implemented entirely using Liquid because I don't know Ruby. This is fine. {% endcomment %} {% assign previousUrl = nil %} {% assign previousTitle = nil %} {% assign currentUrl = '/' %} {% assign currentTitle = 'Volta Docs' %} {% assign nextUrl = nil %} {% assign nextTitle = nil %} {% if page.url == '/' %} {% assign foundCurrent = true %} {% else %} {% assign foundCurrent = false %} {% endif %} {% assign foundNext = false %} {% for section in site.data.sidebar %} {% for doc in section.docs %} {% assign computedPath = section.url | append: doc.id %} {% if foundCurrent %} {% assign nextUrl = computedPath %} {% assign nextTitle = doc.title %} {% assign foundNext = true %} {% break %} {% endif %} {% assign previousUrl = currentUrl %} {% assign previousTitle = currentTitle %} {% assign currentUrl = computedPath %} {% assign currentTitle = doc.title %} {% if page.id == computedPath %} {% assign foundCurrent = true %} {% endif %} {% endfor %} {% if foundNext %} {% break %} {% endif %} {% endfor %}
