HTML Templating Patterns

HTML Templating Patterns

I've decided to try documenting the different patterns used in HTML templates. By HTML templates, I mean taking some HTML(ish) text, and inserting dynamically-generated content. This templating can take place on the web server or in the browser; the patterns don't usually differ between the two.

Delimited HTML

MORF (generic hexagonal Ruby framework) ideas
View morf.rb
# MORF - My Own Ruby Framework #
# This is based on Uncle Bob's talk at Midwest Ruby 2011,
# [Architecture the Lost Years](,
# as well as his article on [Clean Architecture](
# Also inspired by Gary Bernhardt's [Boundaries]( talk,
# and lots of other immutability (functional core) ideas being used within OOP programming (like Piotr Solnica's work).

Prerequisites for HTTP Workshop

Please have Vagrant and VirtualBox installed ahead of the workshop, if possible. We'll be providing a virtual machine (on USB keys) with the lab exercises. Having Vagrant ready to run the VM will help us get started quickly. That said, we'll have a few minutes of slide presentation to get started. You might be able to get things working then. If you're unable to get Vagrant working, we'll have you pair up with a neighbor.

* '...' - Using for Atom.
* "..." - Using for Text.
* [...] - Using this for List (and maybe Map).
* {...} - Using this for Block.
* <...> - No good, as it's too hard to parse differently than < and >.
* (...) - Already overloaded for precedence and method call invocation. Tuple?
* [<...>] - Looks like a really good choice. Map?
* [!...!] - Might be too hard to parse ! inside a List then. (Unless we don't have a ! operator.)
* [@...@] - Probably too hard to parse $ sigil inside a List then.
* [#...#] - Probably too hard to parse comments then. Might use for nestable block comments.

  • Are there any tests cases that are missing? *
    • Unit tests - for any model changes *
    • Acceptance tests - ???infrastructure needed
    • Integration tests - for any front end behavior change *
    • Black box testing? infrastructure needed
    • Controller tests - for any controller changes *
  • Rake / release tasks - manually run them? *

Ideas for new laws

These are ideas that came up during reading articles and discussions about the recent happenings in Ferguson.

New Laws

  1. All police officers shall have their names clearly displayed at all times while in uniform. Violation shall be a felony of impersonating a police officer. The names must be in a legible font, at least 30 points in size.

  2. All police officers shall wear video recording devices. These recordings shall

Ruby ORMs


Rails is really a collection of pieces that can be put together to create a web app. You can enhance or replace many of the components - how you write views, how controllers work, and how you build models. While models are built on top of ActiveRecord in the
