Basic VIM-like editor with basic operations such as:

• insert mode
• view mode
• goto line
• delete line
• goto character
• delete character
• replace word
• delete word
• replace word everywhere
• delete word everywhere
• save
• quit

-> Undo and redo are implemented by using two stacks. The input characters are saved as dynamic list elements and all intrusive operations work by cutting, extracting sequences and optionally, gluing other sequences in their places.

-> Every operation applies right away, after having been read from the input file. That makes the undo operation quite challenging (keep in mind many of the variables are passed as pointers, or references to pointers etc.)

-> If the editor quits before the text being saved, it obviously, returns to the state that was last saved, or empty, if never saved.

-> Input is in editor.in file and the program outputs to editor.out.

For more on how the input should be, check description.pdf or head over to input folder and take a look at the tests.
