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
Oh yes, fun!
This looks really nice, I’ll star it so I remember to download it later
I am glad you like it!
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.
That is extremely cool!
Thank you for your feedback, I am glad you like it.
Almost expected it to be implemented in Electron but was happily wrong. Nice work!
Hahaha, it never entered my mind!
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 [email protected] , 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.
I have now added a tag (0.1.0) on the tui-sudoku repo.
Nice. I made an AUR package for it.
Great, I guess that makes this script readily available to any Arch (+Arch based distros) user who is looking for a sudoku program in the AUR, correct? Thanks very much!
That’s correct. Although the user needs to create folders and copy files into their own home folder, as that’s where the script looks for them. But as a package, we can’t touch it, so it’s a manual step for the user.
Thank you again for the effort and contribution, it is very appreciated.
It is one space off in the first row (numbers)
Do you have this problem from the start? Is this the only problem you are facing? Have you installed the dependecies?
You can see it in the image you linked.
Fixed.
Oh, I see. Phew, you gave me a scare for a moment. That I will fix right now, easy. Thanks for the feedback!
