Dear Gurus,
Here is my first attempt to share my code for auto documentation. It all started with old code maintenance, which my company opted to go for. In order to full-fill the understand the requirement I had to write 'Code-Description' or 'Design' (I know... it is a Bad habit to create Design document after the code is written) documents for all the Perl scripts, which I/somebody else had written. I have developed a script to scan Perl script and create a 'Design report' out of it. This could be modified manually later (It does not give complete description). I have created the Design document the way as per my requirement, however anybody can modify the words. The command line argument would be the 'Name of the script you would like to scan'
Few efforts are required from programmer's side
1) You should write subroutine's description between the word 'sub' and '{'.
2) You should write purpose of the Code, Module in the beginning as (e.g.)
#Purpose:- This code is used to count the number of 'A's
3) Create 3 gifs as per your choice and put those in the same folder.
4) This code will create 3 outputs a) Design report b) Pictorial view of code c) Tree of modules.
I know I am too young to put my code in this section, but your comments would improve my knowledge.
The code goes as follows
The fileoprn.pm is as follows
