which dictionary datasource do you suggest? The OED costs money, and i'm not sure i've heard anything either way about the quality of 'free' versions, though there is the 1913 Websters...
I appreciate you taking the time to look at the source. I used this, like I do most of my side projects, as an opportunity to learn a few things.
I wanted a generic abstraction so that multiple sources could be used. Originally I didn't want or think of the need to support multiple sources, but it quickly became apparent how necessary that was when looking at the quality of free vs paid vs personal-key-required sources.
Sorry, not trying to be a put down. Just a lot of code smells that I see reviewing other people's go at work. Things like the abundance of interfaces, defining your own IO and error handling, use of reflection, and using third party libraries for simple tasks. I'll definitely say the code is at least clean and well documented, so kudos there.
It won't be replacing Dictionary.app, but it does look like a a good subject for learning Go.
