# coding-exercise-photo-site
Generates a static web site about your photos, camera makes and models
## Running it
Drive a sample site here: [http://pokle.github.io/coding-exercise-photo-site/](http://pokle.github.io/coding-exercise-photo-site/)
Or generate it yourself:
bundle install --path vendor/bundle
./generate.rb works.xml output-dir
## Design choices
I hadn't written any Ruby for a couple of years, and it has moved out of my L1 cache. I've been working a lot in Clojure recently, and you'll have to forgive me for trying to achive a functional style in what I would now consider a classical Object Oriented language with mutability running rife.
So here are some of the choices I made:
- Write pure functions where possible
- Don't hold on to state in Objects
- Take all your inputs as a parameter
- Don't modify anything you're sent - it isn't yours
- Return your outputs
- This is a classic data transformation excercise with multiple stages feeding intermediate results to the next
- Don't let downstream concerns flow upstream
- Where possibly, use maps and lists - universal data types that can be consumed and transformed using universal functions that work on data (collect, find_all, group, uniq, ...)
# How does it work?

## Spec
works.xml has information about images:
http://small-image.jpg
http://large-image.jpg
Camera Make
Camera Model
…
generate.rb generates several HTML pages:
- index.html
- Thumbnails of the first 10 photos, and...
- links to all camera makes
- One html file per camera make, each with:
- Thumbnails of the first 10 photos of that make, and...
- links to all that make's models
- link back to the index page
- One html file per camera make-model combo, each with:
- Thumbnails of all the photos of that make-model combination
- link back to the make page
- link back to the index page
