Have you ever wanted a MS Paint in your command line? Ever wanted to play around with pixel art?
Here's a screenshot of Mario that I drew with this program, you can print this same Mario by running cat examples/mario.
On the top-left you will see the state the program is in, these are:
draw (default, not printed), insert (for insert text), and erase (for erasing cells).
Going to the draw state from any other state is done by pressing esc.
Going in the insert state requires pressing i in the draw state.
Similarly the erase state can be entered by pressing e in the draw state.
Pressing b will show you a palette where you can choose the background color of the cell.
Pressing f will similarly show you a palette to choose the foreground (text) color.
In#both modes, pressing b again toggles between normal and bright/bold colors.
Quitting these states is done with esc.
Pressing u will toggle the underline flag.
Quitting the program is done with q. You will have to confirm with y or Y.
Clearing the canvas is done with c, you will also have to confirm that action.
At all times you will see at the top-left formatted text "sample" which displays the applied style.
You can also save the canvas to a file by pressing s, followed by the filename (which will be printed in the top-right), then pressing enter to actually save the file.
You can review the saved canvas by simply cat-ing the file.
When you move the mouse over the canvas the mouse coordinates are visible in the top-right.
If you move your mouse beyond the 223rd column/row then the program will very likely crash, that's unavoidable :(
Execute the command reset and your terminal should be back to its default state.
The whole program is one C program with no dependencies.
This is intentional so the building process can be as simple as gcc termpaint.c -o termpaint,
and the installation process can be as simple as cp termpaint /usr/local/bin (or any other directory in your $PATH.
