TkDiff

Class project made in Python3 with Tkinter.

We were asked to create any kind of software with at least:

• 3 logical instructions,
• 3 graphical elements,
• Communication with anything in any manner (network, COM port, ...).

We thought it would be fun to create a graphical interface for difflib.unified_diff(f1, f2, lineterm=nl) (returns diff line-by-line between two files in an array).

How does it work

• getIP() called only on start to print IP on bottomBar, returns the main IP of the computer,
• DiffWindow contains most functions of the software, __init__() has the window,
• DiffWindow.fileSelctMaster() shows a file selector for the master file,
• DiffWindow.fileSlctSlave() shows a file selector for the slave file,
• DiffWindow.whereAmI() is called everytime user clicks on diffBox (big text box), returns where the user just clicked on the screen,
• DiffWindow.connect() is called whenever user clicks on connectBtn, tells socket to connect on whatever is entered in ipEntry on port 42000,
• DiffWindow.changeDiffBox(text), as I disable diffBox, we cannot tell a function to just write into it, we have to enable it, write text and disable it again,
• DiffWindow.diffServer(), starts a server on port 42000 so another window can connect to it and send content,
• DiffWindow.calcDiff(), puts a multi line string of the diff between f1 and f2 in diffBox,
• DiffWindow.errorHandler(func), is called to handle errors, and does it in a very simple way: just prints in a messagebox.

Whenever DiffWindow is called, a Tkinter window is created, and another thread for DiffWindow.diffServer() is started by it, opening port 42000.

Windows: Communication works only when you start TkDiff as admin
