# Read the log into an array.
@mylog = IO.readlines("path/to/log/file.log")


Now, if you want to get rid of the ANSI escape codes from the log (assuming you are accessing your application/database logs) you will have to use regular expressions. There are two ways of doing this. The first is to get rid of the codes after you read the log file, or do it as you display.

Here are the examples:

# Read the log into an array.
@mylog = IO.readlines("/path/to/log/file.log")

  ALSO:      This is very dirty still and has not been 
             abstracted for use. It is just solving our immediate problems.

  Use cases that must pass (and should be tested someday):
    * Clicking on links updates layout
    * Click around a bit and then use back/forward buttons

client = Riak::Client.new()
bucket = client.bucket('MyBucket')
my_json_obj = bucket.get('MyKey')

my_json_obj.content_type  #=>  "application/json"
my_json_obj.data.to_json  #=>  {"name":=>"Joe"}
my_json_obj.data.to_s     #=>  nameJoe

Should RObject.data.to_s be aliased to .to_json when we know the content_type is json?

# Config for Nginx to act as a front-end for Riak
# The main goal is to proxy all GETs directly to Riak, and disallow anything else (POST, PUT, etc)
# Also, disallow use of the map/reduce query links (i.e. /riak/bucket/key/_,_,_)

# Config is in /etc/nginx/sites-available/default or somewhere like that

# Set up load-balancing to send requests to all nodes in the Riak cluster
# Replace these IPs/ports with the locations of your Riak nodes
