VimQuestCLI

This is a vim implementation in python that tries to implement game using the vim shortcuts.

Why python ?

I love python. Maybe one day it's going to be converted in Rust (for easy webassembly and faster execution). But for now it's python 3.8.

Choice when doing executions

Executor :

• local (the python vim implementation)
• vim (calling vim to execute stuff, for compatibility tests)

Terminal handling :

• Curses wrapper : the way it's usually done in python. It allows for curses to catch the input.
• "manual" curses : Without using the full curses capabilities.

Execution loop :

• One method to start the whole loop.
• One method that have the input as argument and returns what to print.

The python version doesn't have just vim capabilities, but allows to expand for allowing for hooks and data attached to the cells.

Todo

• Separate presentation layer

• Add a vim executor (to be able to compare tests).

• Have a context that is not a copy but modify itself (for speed).

• Have a bunch of hooks, and use them to have game modes.

• Have a command to choose between game modes.

• See how neovim is made so I can use the same architecture.

• Maybe have syntax highliting for game modes too ?

• Activate the UTF-8, see how I can activate it.

• Create docker images for website and terminal.

• Add git hook for cleaning python before commit.

• Use unicode characters (not necesseraly emojii) with colors for differents things happening.

BUG CORRECTION :

• Clean codebase.
• ANSI is blinking.
• Image location is not working.
• Size of the terminal is not used.
• Unicode block behavior is inconsistent.
  • Maybe having replacement for unicode that include colors.

• Python prompt toolking has a python implementation of vi commands :

  • https://github.com/prompt-toolkit/python-prompt-toolkit/blob/master/src/prompt_toolkit/key_binding/bindings/vi.py

Now vim implementationthat I could use for corectness :

• ace js : https://github.com/ajaxorg/ace/blob/master/src/keyboard/vim_test.js
• ideavim : https://github.com/JetBrains/ideavim/tree/master/src/test/java/org/jetbrains/plugins/ideavim

ncurses implementation : https://github.com/mscdex/node-ncurses Maybe this implementation would be easier to understand than the c ncurses one.

Next steps to cover

• [number]command
• i
• aA
• dd
• wbe
• v, Shift-v
• ypP
• "ci

Next step.

Vim core. That execute the commands and return a status. From a Contains the screen size and

Vim window. That take that buffer and return a screen. (matrix of data points with metadata).

Attachable are game modes.

Then there is terminal that push characters and returns a

For inspiration :

• Nethack

Add keystroker counts for speed. Info box to see what's happening in the game.

Game ideas :

• Enemies coming at you and you have to delete the terrain that is underneath them without running out of terrain yourself. But if they touch you, you're dead and has to restart the game.
