sped is a lightweight, primitive text editor

if first command line argument is a file that is opened

stuff marked with [ ] is not yet implemented

features:

- syntax highlighting (C only)
- [ ] good performance even for massive files

keybindings:

notation:

- Control: C
- Shift: S
- Arrow Keys: L, R, U, D

cursor movement:

- L / R / U / D: move cursor
- begin / end: move to begin / end of line
- C-begin / C-end: move to begin / end of file
- [ ] page up / page down: move cursor up / down one page
- C-L / C-R: move to previous / next token
- [ ] C-U / C-D:
    * if parentheses (tokens) are unmatched at cursor position:
      move to previous opening / subsequent closing parenthesis
    * otherwise:
      move to previous / subsequent smaller indentation level

selection:

- S-L / S-R / S-U / S-D: start or continue selection 
- C-c / C-x / C-v: copy / cut / paste
	* operate on the given line if nothing is selected
- C-a / C-t: select all / token

editing:

- character keys: insert character
- backspace: delete
- [ ] tab:
	* if preceding characters are whitespace (incl. newline): indent
	* otherwise: autocomplete token
- [ ] S-tab: dedent
- enter: insert newline (with indentation)
- C-z / C-y: undo / redo

meta:

- C-q: quit
- C-s: save file
- [ ] C-f: find

# Launch Screen Assets

You can customize the launch screen with your own desired assets by replacing the image files in this directory.

You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

# 15

The [15](https://en.wikipedia.org/wiki/15_puzzle) puzzle.

## App

Allows creating, playing & editing puzzles. Includes a solver. Puzzles can be copied to and pasted from clipboard in hex format.
You can click on the neighboring buttons of the blank spots or use WASD or slide gestures to play.

Web (JS) build won't work since the board representation requires 64-bit ints;
might work with the experimental WASM build mode.

## CLI

A simple CLI for the solver is at `cli_solve.dart`.

Run using `dart run cli_solve.dart <hex board>`,
compile using `dart compile exe cli_solve.dart -o solve` (and then run using `./solve <hex board>`).

The output is a sequence of puzzle states, from the given problem to the winning board, as hex, with newlines inserted for better readability.

The hex format is simply a hex string of the hex digits of the 16 tiles; the blank tile is assigned 0. The winning board is stored as `123456789abcdef0` using this format. Whitespace is not allowed.
