Brief Intro

This is a little ruby shell program that records tracks and artists and the play frequency.

Getting Started

After chmod u+x ims, you can run the program just type ./ims
There are two files ims and ims.rb work as main entrance of the program.
Their content is same.
You can run ims either by ruby ims or ruby ims.rb. I've tried PStore and YAML:Store. PStore is quick but not readable while YAML:Store is readable but not so quick.

Data

{ tracks => an array includes artist and played times, ... }

My Solution:

class IMS_Loop :do the loop job
class Commmand :respond to user's commands
class Track_artist :display and add track,artist pair to YAML:Store
JSON data :store the data to and from YAML:Store
Hash data0 :transform data into hash to do the job easily, then restore to data

use case to switch from different commands,
identify by to seperate track and artist,
use a class Track_artist to add new tracks and display,
command Help to see all commands.

Unit Test

test_ims.rb used for testing some commands's performance.

Thank you for reading.
