As almost all text editors do, being able to read the file while editing is a must feature.
For this issue to close, the following need to be complete:

• Scroll on text (pager)
• Insertion
  • Screen
  • File
• Files can be saved and edited (without bugs)
• There are no issues with line wrapping
• Features from previous releases get ported
  • Makefile
  • Reading
  • Line numbers
• Special keys work
  • Arrow keys
  • Enter
  • Control *
  • Backspace + Delete
• Unicode (wchar_t)
• Make code modular and separate it in functions and files

Expected behavior

When typing _ , as stated in the instructions, the program must replace _ with a space character.

Current behavior

The program does not replace _ (underscores) with spaces.

Specs

OS: Ubuntu 20.04
Program ran from: pre-compiled binary

It seems like the pre-compiled binary in the Binaries directory is outdated because when the program is built from source and then ran, its behavior is as expected. Please fix.

Currently, (v0.5) there write more than a single line, isn't supported

Steps to reproduce

Select either 2 or 3. Then on Enter text: type: word1 word2. You will notice that it will skip entering file name. Also, it will have created a file called word2 and its content will be: word1

Expected behavior

Create file with contents: word1 word2

Actual behavior

Described in "Steps to reproduce".

Although the main feature of this program is that it is not what the issue says, there should be a non-interactive way to use it.

Display line number before line content, e.g:

1| Hello world, this is the first line,
2| this is the second line..
3| of a boring text

Currently, there is no feature to move the cursor. If any arrow key is pressed, the cursor won't move. It could be added with ncurses.h. Some documentation can be found here:

• https://tldp.org/HOWTO/NCURSES-Programming-HOWTO/
• http://invisible-island.net/ncurses/ncurses-intro.html
• https://c-for-dummies.com/ncurses/

I don't know how to use this library. I know the basics of the library
Current state:

• Learn basics of ncurses
• Get cursor position
• Move cursor
• Integrate it on the main program

Steps to reproduce

Create a file with the following content:
THE START
Line 2
Line 3

Line 5
Line 6
THE END

Then try to read it.

Expected behavior

to read it properly

Actual behavior

It detects lines correctly (7) but because line 4 is empty it gets ignored. Output below:

THE START
Line 2
Line 3
Line 5
Line 6
THE END
THE END
THE END

If tried to read a file located in a different than your local directory, the program crashes. e.g., the file is located on: /home/user/dir1/dir2 and the program is run on: /home/user/dir1/.

Create a makefile for simplicity. Not needed but it would be fun doing.
