Functional Kats August - lets katas

Hi there

In the build up to Kats Conf (http://functionalkats.com/), (btw we are sold out!! :) ) . Lets meet up and write some code in the form of katas (http://codekata.com/). Bob will warm us up to functional goodness by showing us how to deploy Haskell to AWS.

A quick walkthrough of deploying a Haskell webapp to AWS

Bob Long will give a quick walkthrough of building and deploying a small Yesod webapp to AWS using Packer and Nix. In the space of about 20 minutes we will go from 0 to a running Haskell webservice on EC2, discussing immutable deployments and dependency management along the way

Option 1

String search with patterns (ie cri* would find crisis, crisantemo , criteria ...etc and crisi? will find crisis crisix, crisi ... so * for 0 or more chars and ? for 0 or 1 char in a string )

Given a collection of strings and a pattern return a collection of the original string
pattern can be a combination of literal and wildcard characters, but doesn't support regular expressions. The following wildcard specifiers are permitted in searchPattern.Wildcard specifier

• (asterisk) Zero or more characters in that position.? (question mark) Zero or one character in that position.
  Characters other than the wildcard are literal characters. For example, the string "t" searches for all names in ending with the letter "t". ". The searchPattern string "s" searches for all names in path beginning with the letter "s".
