I tried loading this on Ubuntu 20.04 and get the following result in my terminal. I tried with gnome-terminal and kitty terminal and both had similar results. Not sure if there's something I can do to debug.

The flashes and partial menu showing is from when I push enter on my keyboard.

Not sure you'll want to merge it since it's a huge PR, but here's what I did:

• Put the code in a separate folder in preparation to create setup.py later and turn it into a PyPI package.
• I put getch, clear, hide_cursor and show_cursor in a separate file called cmdpxl_terminal_io to clear up main.py.
• Made the file cmdpxl_datatypes with the classes Color and Pos. In main.py, every list of 3 ints you were using to refer to rgb values is now a Color object, making the code easier to understand and document. Every reference to an index like color[0] are now color.r, color.g or color.b, also improving readability. Same thing was done to positions with Pos.
• Added type hints to most functions.
• Code was reformatted using black to improve readability.
• Added cli support using click, which is simpler and easier to understand than argv.

added --clean flag to have the screen refresh on every input: it makes it a bit flashy, but (at least on my linux terminal), it's the only way not to have a partially drawn image on the right of the screen.

also now it uses the getch module because yes

PyPI package is pretty much ready :)

• Added Github's default Python gitignores to avoid including files generated by setup and other cache files in VCS
• Renamed datatypes and terminal_io to remove package name from file names(both are now imported in __init__.py and can be referenced as cmdpxl.module in code).
• Project package setup almost ready(missing your email)
• Described new installation and usage process in Readme(referencing my branch for now)

Still to do before publication:

• Add your email to author_email in setup.py.
• Change install command in the Readme to reference the PyPI package name instead of my git branch.
• Check if anything else is missing, merge to main branch and publish package.

• Refactor of code and uses class and some methods are isolated in different files.
• CLI more modular, not inside the code itself, only need to be adapted from the Application class.
• Renamed to pixely, this can be changed as original

Hi there, saw your project on Reddit. This is a pretty nice! I've been looking for a nice open-source pixel art editor, so I'm happy I came across something like this.

This PR contains three changes:

• A requirements.txt for more standardized setup. What is typical in projects (if they are not pip-installable) is that the dependencies for a project are listed in a requirements.txt file, which is then used by running pip3 install -r requirements.txt.
• The README has been updated for the above point.
• A .gitignore has been added for users who use Python virtual environments. I typically use this so that I can have more reproducible environments when I collaborate on projects. You can see what GitHub officially posts as a Python gitignore, but this is overkill IMO.

Let me know if you want to make any changes, or if some of these changes are unnecessary. I'll drop the corresponding commits and force-push to this branch.

By the way, I'm running this on Ubuntu 20.04.

I've created a package for cmdpxl in the Arch User Repository. https://aur.archlinux.org/packages/cmdpxl-git/

This pull request adds the necessary command to the readme for installing cmdpxl-git from the AUR as an alternative to using pip.
