Haskell Language Extension Taxonomy

Caveat: It's just personal opinion, and was written to be a bit provocative and encourage discussion . It is also something that is constantly evolving. Some of the main criteria I used in constructing this taxonomy are age, how widely used it us, and how well understood it is by the average Haskell programmer. These things will change over time.

Aso, this is focused on appropriateness for use in commercial production code bases. If you are not thinking about commercial use with a team of multiple

How we're using dry-monad

Imagine that we have an application where user's have a location. We want to find the weather for their current location using an external service call. We want to provide this functionality in a json api. A basic implementation might look like this.

def create
 user = User.find(params[:id])

What's this?

Instructions to obtain ZSH on a windows environment, without the input funny business presented by some other attempted solutions.

The final result is ZSH running on a mintty terminal, emulated by cygwin, and being handled by the popular cmder.

Why is this here?

For the benefit of myself and others. I've already followed these instructions twice. It took me hours to figure all this out, maybe someone else can save a few.

What exactly is covered?

• Installing and setting up cmder
