Field List Comparator

Problem:

1. Take two files and compare the lines that exist in the files. The two files provided are: old_file.txt and new_file.txt.

The files have lines that look like this: TAG : field-list

Solution:

You should create an Python program that compares each tag and for tags that match, compares each space-separated field. The output should be a list of the tags that are in both files and a comparison of the fields that are common, only in the old or only in the new.

Suppress tags where there is an exact match.

For example, given the two lines:

   C_LINK_CMD: lnk2000 -q -c -w -x --heap=0x800 --stack=0x400 -m link.map
   
   C_LINK_CMD: cl2000 -g -z -w -x --heap=0x800 --stack=0x400 -m link.map

Your output should look like this:

Tag Name: C_LINK_CMD
   
Existing Values:  lnk2000 -q -c -w -x --heap=0x800 --stack=0x400 -m link.map
   
New Values:  cl2000 -g -z -w -x --heap=0x800 --stack=0x400 -m link.map
   
Fields Ommitted: lnk2000 -q -c 
   
Fields Added: cl2000 -g -z 

Please sort the output by tag name

How to run:

1. Clone repo
2. Ensure Python 3+ is installed
3. run main.py as follows:

• MacOS / Linux

python3 main.py inputs/Old_File.txt inputs/Old_File.txt

• Windows

python main.py inputs/Old_File.txt inputs/Old_File.txt

3a. You may also pass in different input files by modifying the first and second CLI arguments to refer to a different file.
