Unit testing computed fields

Quick one today. I was writing some code for Sitecore Computed Index fields recently, and it took me more Google Effort than I felt it should have to work out how to write unit tests with FakeDB to verify the code worked. If you want to do that without spending a while searching, the answer is pleasingly simple:

A thought experiment in text parsing

Every so often, every developer finds themselves having to parse data out of text. There are loads of ways of approaching this task, but a lot of pretty unsatisfactory solutions start from "I'll just split up the text by whitespace" or "Hey, let's use regular expressions!". You all remember what regular expressions lead to, right?

As someone who's always on the lookout for something interesting and new to experiment with, I came across an alternative approach to parsing text recently. A blog post I read (I forget what it was, or I'd give credit) linked to the Sprache project on GitHub. This is a text parsing library which lets you construct the descriptions of the text to parse using Linq-style expressions.

So I thought I'd invent an idea for an experimental project to test this out...
