# TODO
## Evil mode
- [ ] it takes 2 keystrokes to go in NORMAL mode
- [ ] keychords in normal mode
- [x] cursor color change based on mode (and stay a block)
## General
- [ ] Ctrl-backspace delete all to the left
- [ ] Dont depend on pywal, simply grab the first 16 colors somehow
- [ ] Kill existing rsh process when spawning a new one from rsh or probably we should kill any other shell idk the standard
- [ ] `cd rsh && ls` DONT work for some reason
- [ ] `2+2` should print automatically without even pressing RET (like node)
- [ ] Better prompt show git info and cool icons (like starship)
- [ ] Syntax highlighting for ruby & Commands red for non existing and green for existing
- [ ] make loops possible by writing a new line instead of immediate execution (like xonsh)
- [ ] Cool stuff like `p = pwd`
- [ ] aliases and functions should be in `~/.config/rsh/config.rb`
- [x] Ctrl-z should not kill the shell
## Functions
- [ ] while this file doesnt exist do
- [ ] while this file exist do
- [ ] for 10 do
- [ ] for 3 seconds do?
- [ ] for a do
- [ ] function to add permanent functions
- [ ] function to add permanent aliases
## Done
- [x] Aliases
- [x] Functions
- [x] Keybinds like ctrl+l up arrow down arrow
- [x] Prompt color based on success or fail
