https://gitlab.com/christosangel/tui-sudoku

Starting the game, and through the main menu, the player can :

  • Start a new game
  • Load previously saved game
  • Configure some parameters (colors, preferred editor, puzzle symmetry,preffered png)
  • exit the program

PLAYING THE GAME

After choosing the n New Game option, the player can select the level of difficulty.

The user will be presented with the known 9x9 sudoku matrix.

Using the shortcuts in the shown cheatsheet table, the player can

MReturn to Main Menu
QShow Solution & Quit
  • Typing H while the cursor is on a number, e.g. 2, will highlight all the 2s in the matrix.Typing H again will undo the highlighting:

-Typing E and entering up to 3 digits, will earmark the cell:

  • Entering an illegal number (a number that already exists in the row, the line or the 3x3 block) will mark the number with a different color, and give a warning message:

While the Moption returns to the Main Menu, and the S option saves the game, the Q option prints the solution and exits:

  • The user can also Undo or Redo their entries with the z or Z option respectively.

Back in the Main Menu, the player can also

  • Load a previously saved game with the l option
  • Configure preferred colors, preferred text editor and puzzle symmetry with the c option
  • or Browse the Top Ten Scores (s option)

The configuration is kept in the $HOME/.config/tui-sudoku/tui-sudoku.config file.

If there is no file kept there, default values will be loaded.

  • You can select the colors you like and the respective codes as they demonstrated here:https://talyian.github.io/ansicolors/Default colors

  • SYMMETRY variable configures the symmetry of the given cells in the 9x9 matrix. Valid options are: none, rotate90, rotate180, mirror, flip, or random
  • PREFFERED_PNG variable defines the png that shows in the notifications. These images are located in the $HOME/.cache/tui-sudoku/png/ directory.

Any feedback is appreciated!

  • ah… that brought back memories to when I wrote my own sudoku-generator

    wanted to know how that one does it's things

    Q="$(qqwing --generate 1 --difficulty $LEVEL --symmetry $SYMMETRY --csv --solution|tail -1|sed 's//0/g')"

    huh

    QQwing is software for generating and solving Sudoku puzzles.

    so it doesn't do the fun parts? sad.

    • Oh, the FUN parts.

      I initially tried to incorporate past attempts to generate a sudoku 9x9 matrix, even added a backtracking routine that would detect and exclude duplicate solutions. Unfortunately, the whole process of generating a new puzzle was taking about 30". What is more, the outcome, although symmetrical and all, was not what I wanted. The routines were in c. You can have a look if you like:

      • Yeah, I'm totally seeing why using qqwing was easier, better and more robust.

        It's the all-around-better way to do that and the developers of that thing probably already spend more time thinking about those problems than we'll ever do.

        But… fun? :-D

    • @DAT @christos divide & conquer 😏

  • hey, this looks really nice. do you have any plans to implement a killer sudoku mode?

    don't know how that could work in terminal with all the small hints and boxes though.

  • Sudoku is basically a game based on concept of latin squares. There's a fun volunteer computing project, actually several of them, that are making a global database of all the possible latin squares. Latin squares have lots of interesting applications, small latin squares are used in scientific studies all the time to control for bias/environment. Who knows what new applications will be found when a big enough database of them exists and can be perused for research.

    All the projects I know of are on !boinc@sopuli.xyz , here's the main one https://boinc.multi-pool.info/latinsquares/

  • Is it possible to get a tag on the repo, so it's easy to package for package maintainers?

    • I have no experience on this procedure, I have not done this before, I need to read some documentation to understand what it is you are asking, and if I can, I surely will. If you send me any helpful link, I would appreciate it.

      • It's pretty simple. :)

        In the gitlab projects page there is a "Tags" section. Click the button to create a new tag, like 0.1.0 or whatever versioning you want, and that's about it.

        That way packagers can target versions, instead of just main branch.
