An example solution to MP assignments in CSCI3359

Note: This solution is only tangentially related to the assignment and has almost no reflection on the steps you need to take to solve MP0

Unlike MP0, this example uses goroutines instead of multiprocess parallelism, so it can be run relatively easily.

go run main.go -f example.json

EVEN BETTER build your go files for darwin/amd64 and include the executable in your final solution. This is the architecture of my laptop and will allow me to easily run your solution without installing the dependencies you used.

export GOOS=darwin 
export GOARCH=amd64 
go build main.go

Then to run it, use

./Example-MP-Solution -f example.json

should produce the following output:

Title: Soll ich heute etwas Brot kaufen?
To: H. Muster
From: F. Muster
Date: 2018-01-22 14:28:00 +0000 GMT
Content: H- ich gehe gerade zum Laden. Brauchen wir Brot?
         -F Muster

There is a message struct in /message/message.go which contains the following fields:

type Message struct{
	To string
	From string
	Title string
	Content string
	Date time.Time
}

It can also initialize a Message from a JSON file via MessageFromJsonFile.

Note: the Date field in the JSON file must conform to Jan 2, 2006 at 3:04pm (MST) format.

Code can be found in /processes/

To simulate MP0, I created two mock processes with their own wrappers of Message. ProcessA is responsible for sending an initialized message over a channel to ProcessB, which is responsible for receiving the message and printing it.

Since we want to simulate TCP communication, I'm using channels with goroutines.

ProcessA is created from a JSON file via ProcessAFromJsonFile and ProcessB can remain unitialized as its message field gets populated from the channel.
